1.1.1 Technical Feasibility
Technical feasibility talks about the project that whether it works with the current technology and equipment
specifying the user requirements. We are providing two platforms; one is for Admin and one is for buyer and
vendor. Peak Property can be developed by using Dart, MS visual studio and Flutter. This application is user
friendly for customer to make it easy to use Peak property provides the platform in which customer sign up
through different ways. This app provides one-to-one chat option for property dealing and provides bookmark
option for save favorite property. This app also has bidding functionality for limited time period.
1.1.2 Operational Feasibility
If the application is fulfilling the admin and user’s operational demands and requirements then the app is said
to be operational feasible.
The operational requirements of our app include:
 The Application is user friendly and easy to use?
 The Application will be available throughout the region
 The Application will be meeting all rules and regulation.
 The Application will be beneficial for the users.
Our application is meeting all above requirements. Thus, we say that our application in an operational feasible
system.
1.1.3 Economic Feasibility
Economic feasibility is a kind of cost-benefit analysis of the project, which assesses whether it is possible to
implement it. This term means the assessment and analysis of a project's potential to support the decision23

Date: 16-May-2022
making process by objectively and rationally identifying its strengths, weaknesses, opportunities and risks
associated with it, the resources that will be needed to implement the project, and an assessment of its
chances of success. This project is economically feasible as it only requires a computer having internet
connection and server.
Personal and implementation costs
 Usage of computer
 Design of database
 Front end Designing
 Error fixing
Our application is meeting these entire requirements; thus, our application is economically feasible.
1.1.4 Schedule Feasibility
Time is an important factor. The assessment and evaluation of the completion of a project with the available
staff and resources within time is very essential. We developed the Gantt chart for the current project. We will
follow the Gantt chart properly. Our project will be completed in about March 2022 approximately.
1.1.5 Specification Feasibility
Requirements of this application are to create good, definite, secures, reliable and online app for searching
property for helping the user to find out property according to their taste. Our application is meeting all these
requirements Thus we say that our application is specification feasibility.
1.1.6 Information Feasibility
Information about different features like properties detail, process of buying and selling property, sign up for
vendor, sign up for buyer, one to one chat, notification, bidding functionality and other demanded function
will be provided. Peak property app is informatively feasible.
1.1.7 Motivational Feasibility
This application is user friendly and fulfilling all requirements of users. Prior knowledge is not requiring to use
the application. Everything will be easy and simple. This application is very responsive, it responds immediately
when user need them or making any mistake. Thus, we say that this application is motivational feasibility.
1.1.8 Legal & Ethical Feasibility
We are developing Peak Property application for which we got the permission from University of Punjab
authorities. The relevant authority claims no issues to start up this project.
1.2 Project/Product Scope
Scope is a very dominant factor of the project. Scope and context both are intertwined as both involve the
boundaries of a project. Context would be referring to the properties of real estate which holds area, prices,
details, attributes, owner details and buyer details. While scope would indicate whatever is describing about
the details of real estate property and at what aspect this property is reliable and useful.
The scope of this project is defined by the real estate properties (selling and buying). Managing project scope
to fit the available properties for living, or for some else use and includes (sellers, buyers, prices and area of
properties) is key to managing successful projects. This project lies in scope of properties of any kind either for
agriculture, living, housing system etc.

1.3 Project/Product Costing
It is said to be the total cost on the Project development/Application development, that how much cost will be
utilized on front-end development and UI designing and back-end code, most of the work in the cost
estimation field has focused on algorithmic, flowchart, and code and cost modeling. In this process costs are
analyzed using mathematical formula as Cost/Fp = Labor rate/ Productivity parameter. This will be equal to
16127.04. This is the formula which is used to calculate the total estimated cost and total estimated effort of
the project development/ app development. For improving the accuracy of project coding, back-end and UI
design will be perfect. There will be no free of cost work in it that may create errors in future. Both are the
directly proportional as cost goes up, accuracy of app will be best.
1.3.1 Project Cost Estimation by Function Point Analysis
Project Cost Estimation by Function Point Analysis:
Number of User Input = 50
Number of User Output = 40
Number of User Enquires = 35
Number of User Files = 06
Number of External Interfaces = 04

1.5 Gantt chart
The Gantt chart identifies the activities and tasks to be performed on the pivot and their corresponding
duration. The tasks recognized and enrolled depend on Gantt chart. It is feasible to plan exercises by solid
beginning for task to be completed. In the solid and perfect beginning methodology, every action is started
right on time as conceivable without disregarding the priority relations. If there is poor start for the duration
then in the poor start approach, every movement is delayed however much as could reasonably be expected
as long as earliest finish time of the project is not compromised. In light of the timetable or Gantt graph
showing the time of project to the task durations or cycles ought to be created. This Gantt graph would
recognize significant achievements with their accomplishment time. It should contain duration assessment of
the necessary of essential task which have to be completed during the project development alongside the
liable for the separate assignments Activity dependencies are also required to be mentioned in it.

1.7 Tools and Technology with reasoning
The application tools, which are to be used on front and back end of the system to be developed, should be
listed. The reasons for these tools should also be described. Identify what the needs for tool support are, and
what the constraints are, by looking at the following:








The development processes. What tool support is required to effectively work? For example, if the
organization decide to employ an iterative development process, it is necessary to automate the tests,
since you will be testing several times during the project.
Host (or development) platform(s).
Target platform(s).
The programming language(s) to be used.
Existing tools. Evaluate any existing and proven tools and decide whether they can continue to be
used.
The distribution of the development organization. Is the organization physically distributed?
Development tools generally support a physically distributed organization differently.
The size of the development effort. Tools support large organizations more or less well.

achieve the goals we set. Goal is to forever change the real estate industry through superior talent,
proven systems & models, and revolutionary technology. We believe that integrity, teamwork,
passion, accountability, and a learning mindset are the key tenets of real success. Our work is much

1.9 Risk List
The greatest risks that real estate brokers and agents/vendor face are fundamentally tied to the
relationships that they form with their clients. The very nature of the real estate business leaves
brokers and agents/vendor subject to any number of potential lawsuits and claims, merely as a result
of their daily business activities. A simple mistake or some bad advice given to a client can result in a
costly lawsuit.
Physical Property Risks:
The number one issue that real estate managers and owners need to be aware of at all times is the
state and condition of their property. No matter how many properties you are running, big or small,
physical property damage is a constant risk. When you are selling and renting property, having to
maintain your real estate is one of your biggest concerns.
Administrative Risks:
If you’re serious about your real estate business, you’re obviously going to have an accountant that’s
keeping tabs on your financials and even a full administrative staff that’s going to handle everything
else that goes into managing real estate; contracts, incidents and claims, tenant information, rent
rolls, maintenance tasks, and more. Even if you’ve hired a number of professionals to handle these
administrative tasks for you, there’s still no guarantee that an administrative error won’t occur. Even
the smallest errors could result in serious losses for your clients, partners, and even tenants, who can
take you to court in order to receive reimbursement.
Cyber risk:
Real estate managers and owners keep a lot of sensitive data on their computers and are constantly
exposed to a large number and variety of cybercrimes. Cyber security statistics show that nearly
every industry is being affected by cyber-attacks, and real estate is no exception. Property managers
store sensitive client, customer, and tenant information such as Social Security numbers, credit card
numbers, and more, making them a vulnerable target for data breaches.
Real estate can be a very rewarding profession for those who are willing to accept the fact that risks
can sometimes be just as great as the rewards involved. And while many can be avoided through
diligence and best practices and some can be significantly mitigated with the help of business
insurance, not all risks can be covered and accounted for in real estate, or any other professional
service for that matter. Making sure that all of your insurable risks are covered as thoroughly as
possible is one of the main responsibilities that real estate business leaders have towards their
companies and something that needs to be a central part of your real estate risk management plan.

*********************REQUIREMENTS ENGINEERING*********************
1.9.1 Systems Specifications
The following are the clauses that must be included while describing the system specifications.
Introduction
Requirements engineering process provides the appropriate demand of the buyer that what type of property
he wants and for what purpose, either it is for agriculture or for living or for any other purpose. There must be
no ambiguity in demand of buyer when he is buying the property, what attributes he wants, what about area,
and there will be reasonable price which will be negotiable for both (seller and buyer). As the requirements of
buyer are clear then it must be easy to find property according to his demand and will meet the good quality
requirements. That seller and buyer are on same page.
Existing System
This application is used to automate the existing manual system. This app will provide sales and purchase
facility for the people. User can easily search for any type of property. This is a user-friendly app.
Organizational Chart

Summary of Requirements (Initial Requirements)
The entire requirement at early stages must be clear by the buyer that in future no miss-understanding will be
there. Each buyer can easily state his requirements to seller, this clause is important for both (seller and
buyer).
1.9.2 Identifying External Entities
The identification of the external entities of all the properties will be based on the information contained in
your domain and list which will give benefit to the buyer to see and match his demands with listed and
identified property. We will map the “Peak Property” app to make things more comprehensible and
understandable.
The Identification of External Entities is done in two phases.
a. Over Specify Entities from Abstract
Under the domain of all the properties attributes any buyer can find his desirable property for his use.
b. Perform Refinement
After over specifying the attributes of properties, buyers have to refine them on the basis of his demanding.

1 Introduction
The goal of the project is to develop an android application for purchasing and buying properties
online. We are developing an online property app “Peak Property”. It is developed by using Dart, MS visual
studio and flutter. This android application will help the people for searching properties according to their
requirement. Online Property dealing becoming very important in our life because nowadays, everything is
online. Anyone who has to sell his property is worried about it and they put up various advertisements for it; it
wastes a lot of time. On the other hand, if someone has to buy any property, he has to search for it. People
have to go different places to find the property according to their need and it also wastes a lot of time. Due to
this process, people face a lot of difficulties. It became a big problem for property dealers. As we know that
internet is a good source for information of every type. Today is the age of social media and everyone use it
very commonly.
To overcome the mentioned problems, we are creating an app which will be a solution for many
problems. Using which people will be able to sell and buy any type of property easily. Anyone who wants to sell
their property will upload their details and will be able to sell it very easily. Who has to buy any type or
property can easily search and buy any type of property according to his need? People will not need any
specific time for this, anyone will be able to check it anywhere and anytime through this app. This app is
divided into two main parts which are admin and user.
In Admin Section, there will be a signup/sign-in page. Through which admin will be authorized to
manage the app. Admin can view the users list and can also add, delete and update property.
In the User section, the user is generalized in two types of user seller and purchaser. First of all, will
user have to enroll him to create a profile or will sign in if he is already an authorized account. After this, user
will easily get the access in the app. If the user is a seller, he will upload his property details and if the user is
vendor, then he can search for any type of property according to his needs.
