PC World(PCW) is a medium-sized company that sells over 50 different types of computer products. The
company has grown steadily in the last 2 years mainly due its popularity over the Internet. They are
finding it increasingly difficult to cope up with all of the paperwork associated with tracking orders due to
the increase of number of orders. The Managing Director is frustrated by the problems associated with
previous traditional 'waterfall' projects. He has decided that PCW will use a company with Agile
development experience to develop the software for a new order tracking system.
JJLP Software (JJLP) is a software development consultant. JJLP is located on the same industrial estate as
PCW. JJLP has purpose built rooms for Facilitated Workshops and Agile software development projects.
The Managing Director of PCW has decided to contract JJLP, on “time and materials” basis, for the
development of the new order tracking system using an Agile development approach.
The new order tracking system will replace the old paper based system and is likely to include some of
the following functionalities:
•
•
•
•
•
•
•
•
Receive a sales order via telephone, fax, post or email – carried out by an Order Handling Clerk;
Create an acknowledgement copy of the sales order with a delivery date after the order has been
confirmed with the warehouse – carried out by a Warehouse Operative ;
Create an acknowledgement copy of the sales order stating the item is out of stock and the date
it will be available after the order has been confirmed with the warehouse – carried out by a
Warehouse Operative;
Credit-check new customers and reject them if they are not creditworthy – carried out by an
Order Handling clerk
Create a daily report of orders that have been dispatched – carried out by the Production
Manager;
Create an invoice for business customers after the delivery – carried out by the Chief Accountant
(M)
Accept credit card payment from domestic customers after the order has been confirmed with
the warehouse - carried out by an Order Handling Clerk;
Create a final demand if a business customer has not paid an invoice after 30 days – carried out
by the Chief Accountant;
The new order tracking system should have the following levels of access:
• report only;
• update only;
• update and delete;
• complete system access;
• All acknowledgement copies of sales orders, invoices and final demands must be printed on
the relevant company headed forms;
• The new order tracking system should be able to print acknowledgement copies of sales orders,
invoices and final demands at a rate of 1 in every 5 seconds. However, an upper limit of 10
seconds would be acceptable.

The MVC pattern of application programming is the current way developers work with

It's also considered a much more easily coded application. MVC also has a stronger
foundation on object-oriented programming (OOP). Other languages use the MVC pattern, so
it's useful to learn it to ensure that your skills can span several areas of development. ........ 41

Activity 1Produce a Software Design Document by analysing a business-related
problem and deduce an appropriate solution including a set of initial
requirements
1.1 Explore a business related problem and produce a well-defined Problem definition
statement supported by a set of user and System requirements.
1.1.1 Problem statement of PCW
. PCW is in need of the order tracking system soon. The old paper work doesn’t eligible for the
increase in the popularity of the company. There too many problems arising form the old
paper work method and if it continues with the current popularity it will become a huge loss
to the company and the popularity and goodwill become useless. The efficiency of the work is
reducing due to the heavy work load to the employees.
1.1.1.1 User requirements.
• The customers should be able gain quick access to the products they order and going to
order.
• The order process should not take too long.
• The user can be able get the required documents straight from the system
1.1.1.2 System requirements.
• The system should be able to handle the traffic of the maximum uses.
• The system should be able to provide necessary source documents to the required parties
without taking too much time.
Agile Methodology and System Analysis
Figure 1 Agile methodology
Introduction: Agile Methodology
Among thousands and thousands of Software Development Methodologies in ever-changing
technology and software world, after the fall of Waterfall, Agile stands out for system analysis
projects and Software development life cycle (SDLC) analysis. "The literal meaning of Agile is
“Able to move quickly and easily", in terms of software development Agile would imply
“flexible” process to respond to changes quickly and the same is true, allowing a developer to
go back to a previous stage and carry out necessary changes there by refining the software
without much delay as compared to the convention plan driven Software development methods
However in terms of system analysis, I can’t agree more with the statement of “Agile is a
mindset defined by values, guided by principles, and manifested through many different
practices”
Figure 2 Agile values
Let’s take a look at principals of Agile Methodology which really eased some consequences of
industry frustration in the 1990s. At that time the software development models which were led
by the Waterfall model were not meeting the requirements and customers’ needs for on time
delivery or meeting the budget or making quick adjustments to the changes of the technology
and software.
Figure 3 Four values of Agile
Unlike linear Waterfall methodology, Agile methodology in system analysis focuses on
flexibility, continuous improvement,managing uncertainty and speed. The four values of Agile
methodology guaranteed to the clients on change is always welcomed, evolving requirements
can easily be adapted. Faster and high-quality delivery is highlight along with strong agile team
interaction, continuous feedback from users. Furthur more,, customers will have all the
opportunities to see the smaller chunk of work being delivered in the process, to share their
input, and to have a real impact on the end product without worrying about jargons from
developers or piles of documentation given to them as a whole in the very end of project before
system design and implementation. Besides the four values, we can’t ignore the 12 Agile
principles involved in Agile methodology as follows:
Figure 4 12 Agile Principals
Agile Scrum methodology VS Kanban method VS Scrumban
Figure 5 Scrumban Methodology
Scrum is an agile method for project management or framework used primarily for software
development projects.Its goal is to dramatically improve productivity in teams and to deliver
new software every 2-4 weeks. Agile Scrum methodology involves forming teams with
diversity, strong communicative teamwork, frequent feedbacks from clients, a lot of
participates of users etc.
Figure 6 Team Trail Head
Kanban is one of the most popular software development methodologies adopted by agile
teams today. Like Scrum, Kanban is a process designed to help teams work together more
effectively.However there are some differences that you can not ignore as an Agile lover.
Agile model for improving The Software (System) Development Life Cycle
Figure 7 Development Life cycle
When talking about system development life cycle (SDLC), we certainly mean a series of
stages or phases which provide a systematic model for the creation and management of a
software application.(Fig. 4). Additionally, as system analysts, we make a detailed plan after
problem analysis , solution requirement analysis and design analysis before the software
development processes such as implement, test, maintenance and replacement will take place.
There are several important development models in general use.In terms of what’s required of
the application, and how costs and resources are allocated, correctly applied model will enable
SDLC to keep all clients and users in a software project on the same page and to deliver work
without delay. A well-documented and performed SDLC can also ensure high levels of product
quality, application security, and management control. The most common models are listed as
follows:
1. Waterfall model : sequential, linear development model.It is the oldest SDLC model
following a straight line path from one phase of the process to another, as each completed
phase “waterfalls” into the next. A lot of delays at any stage can seriously hamper the
entire process.
2. V-shaped model: an extension of the waterfall model, featuring a testing round at each
development stage; (mainly focus on verification and validation);
3. The Big Bang Model: a higher-risk SDLC model which focuses mostly on the coding
stage, and places little emphasis on a system analysis.
4. Spiral model:the most flexible of the SDLC models, achieving software optimization
through a repetitive process where planning, design, building and test phases are run over
and over again, with little improvement or progress at each repetition.
5. Agile model (Figure 8): produces a succession of releases; allows a working phase to be
delivered very quickly. The testing of each release provides feedback for improving the
next release.Agel model has three main attributes: “ Software is developed in fact,
incremental cycles; Each version is tested to ensure product quality; It is used for
applications that must be completed in a critical time frame.
1.2 Determine any areas of risk related to the successful completion of your application.
1. Estimation and scheduling
•
The unique nature of individual software projects creates problems for developers and
managers in estimating and scheduling development time. Always monitor existing
projects so that you apply lessons learnt in the future.
2. Sudden growth in requirements
•
As a project progresses, issues that are not identified earlier can create a last-minute
hurdle to meeting deadlines. Try to think big early on in the project, and anticipate the
worst case or heaviest-use scenario.
3. Employee turnover
•
Every project has a number of developers working on it. When a developer leaves, he
or she may take critical information with him/her. This can delay, and sometimes derail
an entire project. Ensure you have resources where team members can collaborate
and share knowledge.
4. Breakdown of specification
•
During the initial phases of integration and coding, requirements might conflict.
Moreover, developers may find that even the specification is unclear or incomplete.
5. Productivity issues
•
On projects involving long timelines, developers tend to take things easy to begin with.
As a result, sometimes, they lose significant time to complete the project. Set a
realistic schedule, and stick to it.
6. Compromising on designs
In order to get stuck into the next ‘real’ tasks, developers tend to rush the design-process.
This is a waste of programming hours, as designing is the most critical part of software
development.
7. Gold plating
•
Developers sometimes like to show off their skills by adding unnecessary features. For
instance, a developer might add Flash to a basic login module to make it look ‘stylish’.
Again, this is a waste of programming hours.
8. Procedural risks
•
Day-to-day operational activities might hamper due to improper process
implementation, conflicting priorities, or a lack of clarity in responsibilities
9. Technical risks
•
Sometimes software development firms reduce the functionality of the software to
compensate for overruns pertaining to high budgets and scheduling. There is always a
conflict between achieving maximum functionality of the software and peak
performance. In order to compensate for excessive budget and schedule overruns,
companies sometimes reduce the functionality of the software.
10. Unavoidable risks
•
These include changes in government policy, the obsolescence of software or other
risks that cannot be controlled or estimated. As the field of software development
becomes more and more complex, the risks associated with it have intensified. It is
vital that development firms focus on strategic planning to mitigate such risks.
1.3 Analyse a business related problem using appropriate methods and produce a wellstructured Software Design Document that defines a proposed solution. Include relevant
details on requirements, system analysis, system design. (propose a suitable language)
1.3.1 Introduction:
The proposed PCW project will introduce a new way of tracking orders in a better mechanism
which will help not only keeping track of orders but also help in generating the reports and
maintaining the stock supply.
1.3.2 Purpose:
The purpose of this project is to deliver user friendly software which will be make the
company capable of handling thousands of orders daily and generate the reports to keep track
of company’s performance in the market.
1.3.3 Background:
When the companies keep track of daily orders on papers, it become difficult to manage the
records when the company grows. The orders increase and the employees find it difficult to
generate reports, counts etc for the orders. This project system will provide an software
solution to this problem and keep track of orders and reports online without errors.
1.3.4 Goals: The main goals of the system are listed as below:

associated with the creation of a business application
2.1 Research the use of software development tools and techniques and identify any
suitable tool or technique that you may select for the development of this application.
Bootstrap
Bootstrap is the best HTML, CSS and JavaScript framework for any web developer. It will help
you quickly produce responsive, clean looking websites. It does this simply by providing you
with a ton of pre-built CSS and JavaScript for lists, navigation bars, forms and lots of other web
elements.
With Bootstrap you can focus more on the website you wanted, and spend less time wrestling
with some of the CSS issues, media queries, and cross-browser compatibility.
Since Bootstrap is basically just a collection of CSS and JavaScript files, you can always
customize any of it as much as you want. All you have to do is just to implement it and modify it
to your website features and needs.
History of Bootstrap
Bootstrap, originally named Twitter Blueprint, was developed by Mark Otto and Jacob Thornton
at Twitter as a framework to encourage consistency across internal tools. Before Bootstrap,
various libraries were used for interface development, which led to inconsistencies and a high
maintenance burden. According to Twitter developer Mark Otto:
"A super small group of developers and I got together to design and build a new internal tool and
saw an opportunity to do something more. Through that process, we saw ourselves build
something much more substantial than another internal tool. Months later, we ended up with an
early version of Bootstrap as a way to document and share common design patterns and assets
within the company.
After a few months of development by a small group, many developers at Twitter began to
contribute to the project as a part of Hack Week, a hackathonstyle week for the Twitter
development team. It was renamed from Twitter Blueprint to Bootstrap, and released as an open
source project on August 19, 2011. It has continued to be maintained by Mark Otto, Jacob
Thornton, and a small group of core developers, as well as a large community of contributors.
On January 31, 2012, Bootstrap 2 was announced. This release added the twelvecolumn grid
layout and responsive design components, as well as changes to many of the existing
components. The Bootstrap 3 release was announced on 19 August 2013, moving to a mobile
first approach and using a flat design.
On October 29, 2014, Mark Otto announced Bootstrap 4 was in development. The first alpha
version of Bootstrap 4 was deployed on August 19, 2015.
Features of bootstrap
Easy to use
Anybody with just basic knowledge of HTML and CSS can start using Bootstrap
Responsive features
Bootstrap's responsive CSS adjusts to phones, tablets, and desktops
Mobile-Friendly
Mobile-first approach: In Bootstrap 3, mobile-first styles are part of the core framework
Simple Integration
Bootstrap can be simply integrated along with distinct other platforms and frameworks, on
existing sites and new ones too and one more things you can also utilize particular elements
of Bootstrap along with your current CSS.
Pre-styled Components
Bootstrap approaches with pre-styled components for alerts, dropdowns, nav bars, etc.
Customizable Bootstrap
The Bootstrap can be customized as per the designs of your project.
Browser compatibility
Bootstrap is compatible with all modern browsers (Chrome, Firefox, Internet Explorer, Safari,
and Opera)
Great grid system
Bootstrap is built on responsive 12-column grids, layouts and components. Whether you need
a fixed grid or a responsive, it's only a matter of a few changes.
Bundled JavaScript plugins
The components such as drop down menu are made interactive with the numerous JavaScript
plugins bundled in the bootstrap package.
Extensive list of components
Whether you need drop down menus, pagination or alert boxes, Bootstrap has got your
covered. Some of the components pre styled are; Dropdowns, Button Groups, Navigation Bar,
Breadcrumbs, Labels & Badges, Alerts, Progress Bar, And many others.
Base styling for most HTML elements
A website has many different elements such as headings, lists, tables, buttons, forms, etc. The
HTML elements for which styles are provided are; Typography Code, Tables, Forms,
Buttons, Images, Icons
Good documentation
Not only does Bootstrap offer styling for almost every element a typical website or web
application requires, it also provides a great documentation with examples and demo that only
make it more easier for even someone new. (Source: (bootstrap-features-of-bootstrap))
C# Language
C# is a Windows programmer go-to language. It's the preferred language for any desktop or
web application that runs on a Windows computer. C# is a part of the ASP.NET framework, so
you'll hear it mentioned along with VB.NET. You have these two language options when you
decide to learn Windows platform development. If you prefer C-style language syntax, C# is
the direction you should go when learning Windows development.
History of C#
C# is one of the newer languages on the market. You'll run into plenty of JavaScript libraries
popping up in certain programming circles, but these aren't languages – they are add-on libraries
to the JavaScript language. Disregarding all of those JavaScript libraries, C# is one of the newest
languages developed by Microsoft.
Originally, Microsoft developed and deployed the ASP (Active Server Pages) language. This
language is now called Classic ASP, and its support has been discontinued. ASP let programmers
create VB-like scripts to develop dynamic web pages. These web pages ran on older Internet
Information Services (IIS) servers running Windows. Some Linux providers also supported
Classic ASP, but it was usually a non-standard way to create web pages.
In the late 1990s, Microsoft decided to create a language that would compete with Java. During
this time, Java was the most common language, and its popularity was rising. Classic ASP had
its place, but the software needed to create the product was a paid application. Java was used to
create web applications, and it was preferred among developers who understood C and C++.
In 2000, Microsoft released its first version of C# as a part of the .NET framework. VB.NET was
also an option, but VB.NET followed the standard Microsoft Visual Basic syntax while C# was
similar to Java, which is also a C-style language.
Initially, C# was not as popular as VB.NET. Since many Windows desktop applications were
written in Visual Basic and web applications were written in Classic ASP, the language of choice
for developers at the time was VB.NET. VB.NET was an easier language to migrate to when
changing to the newer framework. However, the language of choice started to shift as more
people realized the similarities between Java, C and C#.
The name given to C# was originally "Cool." Microsoft knew that it was working with a
language very close to C++, so they wanted to indicate that its new language was one step above
C++. Instead of naming the new language C+++, they decided to go with the name C#
(pronounced C sharp), which references the musical notation that a note should be higher in
pitch.
Through the years, C# finally gained traction as a preferred Microsoft language. What makes C#
different than most popular coding languages on the web is that the code is closed-source. Opensource coders claim that C# and other closed source languages are too difficult to work with, but
closed source has its advantages.
First, working with any Microsoft platforms is much easier with the company's own language
and frameworks. You could run open-source languages such as PHP or even Java on Microsoft
web servers, but it's much more cumbersome and includes more overhead than just using
Microsoft's natural language used in Windows applications. C# also works well with Microsoft's
SQL Server database backend. In most companies that run C#, the database choice is Microsoft
SQL Server. Both the language and the database work seamlessly together. You can also work
with open-source database solutions with C#, but it's more common to keep the platforms related
when working with high-end enterprise solutions.
Second, closed source applications could be considered more secure. If a hacker is able to gain
access to a web server with open-source coding, the hacker now has access to the entire source
code for the application. With C#, the language is compiled and DLLs stored on the web server.
If a hacker gains access to the web server, he only has compiled binary files. This still isn't a
guarantee that the hacker can gain access to the source code. There are plenty of decompilers on
the market, but it makes it much harder for a hacker to view the source code. The C# language
even lets you encrypt the password stored in the site's web.config file, which is where many of
the sites settings are found.
Another advantage of C# is that these sites are not the main target for hackers. Hackers prefer
out-of-the-box solutions such as WordPress and Joomla. These sites become targets, and are
much more easily scanned and breached.
Interested in learning more? Why not take an online class in C# Programming?
Finally, C# works well with the Visual Studio environment. Microsoft assumes that its code is
used by small and large application design shops. With larger shops, the need for collaboration
tools requires an environment that allows coders to check in, check out, merge, and roll back
code. The Visual Studio environment along with Team Foundation server gives developers this
option.
C# and ASP.NET in general have gone through a different style of coding. The original
framework required developers to work with web forms. Web forms are a framework that lets
the developer control all aspects and events of a page including when the page loaded, the way
elements rendered on the page, and when the page stopped loading. Developers could also
change the habits of a page that was unloaded from the server. These web forms remained the
standard style of .NET programming until a few years ago.
In 2009, Microsoft released an entirely new framework from which developers could create web
applications. The MVC (model-view-controller) pattern is a way for coders to create web
applications without the cumbersome way web forms required coders to control the way pages
load. MVC was a complete overhaul to the way coders were used to creating C# applications.
With MVC, the developer does not need to worry about the way a page loads or how it unloads.
Elements are not controlled through events, and they don't need rendering from the standard web
form interface. Instead, coders created models, views, and controllers. A model represents the
way a data object is laid out. A view is the HTML page (named CSHTML in MVC) displays on
the browser. The controller contains the business logic and code workflow for the frontend
design.
The MVC pattern of application programming is the current way developers
work with applications. Web forms are still found in some older, legacy
applications, but you won't see them as much as MVC. MVC is considered
the most powerful version of the .NET framework. It's also considered a
much more easily coded application. MVC also has a stronger foundation on
object-oriented programming (OOP). Other languages use the MVC pattern,
so it's useful to learn it to ensure that your skills can span several areas of
development.
SQL Server Management Studio
Figure 11 SQL Server Management Studious
SQL Server Management Studio(SSMS) is a software introduced by Microsoft used for managing
and administrating Microsoft SQL Server. It consists of many features and attributes that helps
working with the Microsoft Server. One of the most highlighted feature of SSMS is the Object
Explorer allowing the user to work upon any of the objects residing inside the server. SSMS
provides user with both the script editing and GUI platform for working with the objects in the
server simplifying the process as a whole.
Some of the features of SSMS comes from
•
Enterprise Manager
•
Query Analyzer
•
Analysis Manager
And not to forget the features in previous version of SQL Serve r is also included.
Furthermore, SSMS comes with many components with the single, integrated
environment.
Some of them are
•
Object Explorer: manage objects in SQL Server
•
Template Explorer: manage text files
•
Solution Explorer: manage administrative items like queries and scripts
SSMS operates only on the Windows Operating System. But, it can even be remotely connected
to Linux SQL Server Instances.
Introduction to C#
C# is a general-purpose, modern and object-oriented programming language pronounced as “C
sharp”. It was developed by Microsoft led by Anders Hejlsberg and his team within the .Net
initiative and was approved by the European Computer Manufacturers Association (ECMA) and
International Standards Organization (ISO). C# is among the languages for Common Language
Infrastructure and the current version of C# is version 7.2. C# is a lot similar to Java syntactically
and is easy for the users who have knowledge of C, C++ or Java.
A bit about .Net Framework
.Net applications are multi-platform applications and framework can be used from languages like
C++, C#, Visual Basic, COBOL etc. It is designed in a manner so that other languages can use it.
know more about .Net Framework
Why C#?
C# has many other reasons for being popular and in demand. Few of the reasons are mentioned
below:
1. Easy to start: C# is a high-level language so it is closer to other popular programming
languages like C, C++, and Java and thus becomes easy to learn for anyone.
2. Widely used for developing Desktop and Web Application: C# is widely used for
developing web applications and Desktop applications. It is one of the most popular
languages that is used in professional desktop. If anyone wants to create Microsoft apps,
C# is their first choice.
3. Community:The larger the community the better it is as new tools and software will be
developing to make it better. C# has a large community so the developments are done to
make it exist in the system and not become extinct.
4. Game Development: C# is widely used in game development and will continue to
dominate. C# integrates with Microsoft and thus has a large target audience. The C#
features such as Automatic Garbage Collection, interfaces, object-oriented, etc. make C# a
popular game developing language.
Beginning with C# programming:
Finding a Compiler:
There are various online IDEs such as GeeksforGeeks ide, CodeChef ide etc. which can be used
to run C# programs without installing.
Windows: Since the C# is developed within .Net framework initiative by Microsoft, it provide
various IDEs to run C# programs: Microsoft Visual Studio, Visual Studio Express, Visual Web
Developer
Linux: Mono can be used to run C# programs on Linux.
Programming in C#:
Since the C# is a lot similar to other widely used languages syntactically, it is easier to code and
learn in C#.
Programs can be written in C# in any of the widely used text editors like Notepad++, gedit, etc.
or on any of the compilers. After writing the program save the file with the extension .cs.
Explanation:
1. Comments: Comments are used for explaining code and are used in similar manner as in Java
or C or C++. Compilers ignore the comment entries and does not execute them. Comments can
be of single line or multiple lines.
Single line Comments:
Syntax:
// Single line comment
Multi line comments:
Syntax:
/* Multi line comments*/
2. using System: using keyword is used to include the System namespace in the program.
namespace declaration: A namespace is a collection of classes. The Hello World App
namespace contains the class Helloworld.
3. class: The class contains the data and methods to be used in the program. Methods define the
behavior of the class. Class Helloworld has only one method Main similar to JAVA.
2.2 Compare the differences between various software development tools and techniques
researched. Justify your preferred selection and preferred software development
methodology.
2.2.1 The Agile Software Development Method Uses an Iterative and TeamBased Approach
One main difference between the traditional and agile methodologies is the sequence of the
phases in which the software development project is completed. The traditional method uses
a linear approach, where the stages of the software development process must be completed
in a sequential order. This means that a stage must be completed before the next one begins.
These stages usually comprise the following:
1. Requirements gathering and documentation
2. System design
3. Code and unit testing
4. System testing
5. User acceptance testing
6. Bug fixes
7. Product delivery
On the other hand, the agile methodology uses an iterative and team-based approach. Its
main objective is to quickly deliver the application with complete and functional components.
Instead of completing the software development tasks in sequence, they are completed in
sprints that run from around one to four weeks and where a list of deliverables is completed
in each sprint. The tasks that do not get completed within the sprint are then reprioritized and
included in future sprints. This also means that the different stages of the software
development life cycle can be revisited as needed.
The typical agile approach involves the following stages:
1. Project initiation
2. Sprint planning
3. Demos
With the traditional method, the details of the entire project have been visualized and defined
before the project starts. In contrast, the agile methodology allows for more flexibility in that
changes can more easily be made even after the project starts. It is best employed if the scope
of the project cannot be clearly defined in advance. This also means that making unplanned
software development changes with the traditional method is costlier than with agile.
The Agile Method Requires More Customer Involvement Customers are highly involved in the
early stages of the software development process when employing the traditional
methodology. More specifically, their input is needed during the requirements gathering
phase, as they must provide a detailed description of what their requirements are with
regards to the software application to be developed and how they envision it to function.
(dzone.com, 2020)
However, they have limited involvement after the software development process starts, aside
from attending status meetings, doing reviews, and providing approvals. The Admin usually
get to see the product in its entirety after a software development life cycle is completed.
In contrast, the customers are highly involved in every stage when employing the agile
development process. They can review the application at every phase and make suggestions
for improvement. As a result, the customers are more engaged in the entire software
development process, in turn ensuring that they are satisfied with the finished product. The
Traditional Method Has a More Formal Documentation and Review Process Each phase of the
development process is properly documented and reviewed when using the traditional
approach. On the other hand, due to the quick delivery time required with the agile method,
changes are usually made directly on the code, with the developers just adding comments and
annotations. (dzone.com, 2020)
2.3 Justify the tools and techniques chosen to realize a custom built website. Justify your
preferred selection of tools and techniques in deducing an appropriate solution to a
business related problem.
2.3.1 Browsers
Browsers are the interpreters of the web. They request information and then when they
receive it, they show us on the page in a format we can see and understand.
Google Chrome - Currently, the most popular browser brought to you by Google
Safari - Apple’s web browser
Firefox - Open-source browser supported by the Mozilla Foundation
Internet Explorer - Microsoft’s browser. You will most often hear web developers complain
about this one
Source:(Differential.com, 2020)
2.3.4 Programming Languages Programming languages are ways to communicate to
computers and tell them what to do. There are many different programming languages just
like there are many different lingual languages (English, Spanish, French, Chinese, etc). One is
not better than the other. Developers typically are just proficient at a couple so they promote
those more than others. Below are just some of the languages and links to their homepages
1. Javascript - used by all web browsers, Meteor, and lots of other frameworks
2. Coffee script - is a kind of “dialect” of Javascript. It is viewed as simpler and easier on your
eyes as a developer but it complies (converts) back into Javascript
3. Python -used by the Django framework and used in a lot of mathematical calculations
4. Ruby - used by the Ruby on Rails framework
5. PHP - used by Wordpress
6. Go - newer language, built for speed.
7. Objective-C - the programming language behind iOS (your iPhone), led by Apple
8. Swift - Apple’s newest programming language
9. Java - Used by Android (Google) and a lot of desktop applications.

3.3 Evaluate any new insights, ideas or potential improvements to your
system and justify the reasons for including/not including them as a part of
this business application.
Apart from the functions requested in the scenario there can be more features we can include
in the proposed system .
1. Online ordering by the customers. By this customer don’t have to come to the physical
place to order and buy the product.
2. Invoices can be sent to the customer by e-mail. From this, dealing with paper is fully
reduced and the customers will be able to review their invoices at home or wherever they are.
3. Thee can be a customer profile section where customers can; By implementing this
customer can be able to monitor what they have ordered and when will they be able to collect
those from the PCW.
a. View their profile.
b. Order products.
c. View newly added products
4.Admin can have access to almost entire system to go through and track the company’s
status. By thus manager can know how much the company performs in specific time periods.

Activity 4
LO4 Evaluate the performance of a business application against its Software
Design Document and initial requirements
4.1 Review the performance of your business application against the Problem Definition
Statement and initial requirements.
The performance of the application developed will diminish the problems stated in the
problem definition statement and all the initial requirements are covered. This
implementation will be a huge upgrade to the current system of order tracking.
4.2 Critically evaluate the strengths and weaknesses of your business application and
justify opportunities for improvement and further development.
Order tracking system refers to a system which provides information about the status of the
order placed by a consumer. This particular system facilitates the customer's effort in
inquiring the position of their order at any given point of time. It provides detailed
information with respect to the journey of a product from the warehouse to its customer.
With the advent of technology, the traditional paper-based system of keeping a track of the
orders has been substituted by the modern online order tracking mechanism. PC world (PCW)
wants to shift from the conventional mode of tracking order to online order tracking system.
The company has contracted with a software consultant company to develop an app for the
new order tracking system. The potential risks involved in the completion of the development
of the application is enumerated in the explanation part.
Explanation:
Order tracking system refers to a system which provides insights into the status of the order
placed by a consumer. This particular system facilitates the customer's effort in inquiring as to
where their order is at any given point of time. Till the order is delivered to the doorsteps of
the customers they can track their order With the advent of technology, the traditional paperbased system of keeping a track of the orders has been substituted by the modern online
order tracking mechanism. PC world (PCW) wants to shift from the conventional mode of
tracking order to online order tracking system. The company has contracted with a software
consultant company to develop an app for the new order tracking system.
With the sudden shift, there arises risks with respect to the successful implementation of the
application (order tracking system).
1. The new system requires visibility across the various systems and processes. The
transparency must now be manifested online. The people handling the system might not be
efficient enough to handle the same.
2. Earlier, the order tracking system was based on paper tracking. The company might not
have professionals who are adept at operating the new app developed for tracking orders.
They might not know how to operate the same on a computer.
3. The company might even face the paucity of professionals to operate the new order
tracking system. There might arise the need to hire more people who have proper training to
operate the new online tracking system in order to work efficiently.
Therefore, the company should have these risks in contemplation before rolling out the new
app for tracking orders
