Why use SDLC?
 Helps to manage the project: SDLC provides a structured approach to software development,
which helps in managing the project from start to finish. It helps in defining the scope of the
project, identifying risks and constraints, and creating a plan to execute the project within the
given timeline and budget.
 Ensures high-quality software: SDLC emphasizes testing and quality control at every stage of the
development process, which helps in identifying and resolving defects early in the development
cycle. This, in turn, leads to the delivery of high-quality software that meets the customer's
requirements.
 Reduces development time and cost: SDLC provides a systematic approach to software
development, which helps in reducing the development time and cost. It helps in identifying
potential issues early in the development cycle, which reduces the time and cost required to fix
them.
 Facilitates communication and collaboration: SDLC involves collaboration between different
stakeholders, including project managers, developers, testers, and customers. This collaboration
helps in ensuring that everyone is on the same page and working towards the same goal.
 Provides a roadmap for development: SDLC provides a roadmap for software development, which
helps in identifying what needs to be done at each stage of the development process. This
roadmap ensures that the development team is working towards a common goal and helps in
avoiding scope creep or other issues that could derail the project.
LO1: Describe different software development lifecycles
P1: Describe two sequential and two iterative software lifecycle model
Two Sequential models
Waterfall Model:
The Waterfall model is a popular software development model that follows a linear and sequential
approach to software development. It consists of a series of phases that are completed one after the
other, with each phase acting as a foundation for the next phase. The phases in the Waterfall model
include requirements gathering, design, implementation, testing, deployment, and maintenance . The
Waterfall model is characterized by its rigidity and lack of flexibility. Each phase must be completed before
moving to the next one, and changes cannot be made once a phase is completed. This makes it challenging
to accommodate changes in requirements, and any changes must be addressed in subsequent phases,
which can be time-consuming and costly.
Waterfall 1
Advantages





The Waterfall model works best when the requirements are clear, well-defined, and fixed.
The Waterfall model is easy to understand and manage, as it follows a clear and structured
approach to software development.
This model processes and completes steps one at a time. Phases don't cross over.
This model is straightforward, understandable, and practical.
The Waterfall model emphasizes testing at every stage of the software development process. This
ensures that any defects are identified and fixed early, reducing the cost and time required to fix
them.
Disadvantages





The Waterfall model is rigid and does not allow for changes to be made once a phase is completed.
This can be problematic if the requirements change, as any changes must be addressed in
subsequent phases, which can be time-consuming and costly.
The Waterfall model follows a sequential approach, with each phase building on the previous
one. This can result in a long development cycle, as each phase must be completed before
moving to the next one.
The Waterfall model can be risky, especially if the requirements are not well-defined or if the
technology is new and evolving. If any problems are identified late in the development process, it
can be difficult and costly to fix them.
The Waterfall model does not emphasize customer involvement during the development process.
This can result in a product that does not meet the customer's needs or expectations.
The Waterfall model emphasizes testing at the end of the development process. This can be
problematic if any defects are identified
V shaped model
The V-shaped model is a software development model that is an extension of the Waterfall model. It is
sometimes called the Verification and Validation model or the Validation model. The V-shaped model
emphasizes the importance of testing at each stage of the software development process, starting from
the requirements phase and ending with the deployment and maintenance phase. It is called the V-shaped
model because of its V-shaped diagram that represents the relationship between the development phases
and the corresponding testing phases.
Advantages:

The V-shaped model emphasizes testing at each stage of the development process, which helps
to identify defects early.




The V-shaped model requires a clear and well-defined set of requirements before the
development process begins. This helps to ensure that the software meets the needs and
expectations of the end-users.
The V-shaped model requires clear and detailed documentation at each stage of the development
process. This helps to ensure that everyone involved in the development process understands the
requirements, specifications, and design of the software.
The V-shaped model helps to reduce the risk of software failure by emphasizing testing at each
stage of the development process.
The V-shaped model encourages better collaboration between the development team and the
testing team.
Disadvantages:





The V-shaped model is a rigid and inflexible model that does not accommodate changes easily.
Once a phase is completed
The V-shaped model does not allow much scope for creativity because it follows a sequential and
linear approach to software development.
The V-shaped model requires a clear and well-defined set of requirements before the
development process begins.
The V-shaped model emphasizes testing at each stage of the development process, which can
lead to delays in the development process
The V-shaped model does not emphasize customer involvement or feedback until the acceptance
testing phase
Two iterative models
Agile model:
The Agile model is an iterative and incremental approach to software development that emphasizes
flexibility, collaboration, and continuous improvement. It is based on the idea of iterative development,
where requirements and solutions evolve through collaboration between self-organizing, crossfunctional teams. The diagram of the Agile model is a spiral-like loop, with each loop representing an
iteration of the development process. Each loop consists of four stages: Planning, Design, Development,
and Testing
Advantages





Agile model is flexible and allows for changes to be made easily throughout the development
process.
The Agile model encourages the delivery of working software in shorter increments, which
means that features can be released to users faster.
Agile development emphasizes collaboration and communication among team members,
stakeholders, and customers.
The Agile model emphasizes transparency and visibility into the development process. This
means that stakeholders and customers can see the progress being made and provide feedback
along the way.
The Agile model promotes continuous improvement and learning through regular feedback and
retrospectives.
Disadvantages


Agile development can be less predictable than other software development methodologies
because it is designed to be flexible and adapt to changing requirements.
Agile development emphasizes working software over documentation. While this can be an
advantage in some cases, it can be a disadvantage in situations where documentation is
important, such as when regulatory compliance is required.




Agile development relies heavily on collaboration and self-organizing teams. This means that
team
members must have the skills and experience to work together effectively, which can be
challenging for new or inexperienced teams.
Agile development requires regular communication and collaboration among team members,
stakeholders, and customers. This can be challenging when team members are distributed
across different locations or time zones.
Agile development relies on active customer involvement throughout the development process.
This can be a challenge if customers are not available or do not have the necessary expertise to
provide feedback.
Spiral model:
The spiral model is a software development process combining elements of both design and
prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. The
spiral model is intended for large, expensive, and complicated projects. It combines the idea of iterative
development with the systematic, controlled aspects of the waterfall model. The spiral model has four
phases: Planning, Risk Analysis, Engineering and Evaluation. In the planning phase, the objectives,
alternatives, constraints and requirements
Advantages:

The Spiral Model is highly adaptable and can be tailored to meet the unique needs of each
project. This makes it well-suited for complex projects with changing requirements.




The Spiral Model emphasizes risk analysis and management, which allows for potential risks to
be identified and addressed early in the development process.
The Spiral Model allows for incremental development and testing, which can help to ensure that
the software is meeting the needs of stakeholders and end-users throughout the development
process.
The Spiral Model promotes continuous feedback and communication with stakeholders and
end-users, which can help to ensure that the software meets their needs and expectations.
The Spiral Model emphasizes quality assurance and testing throughout the development
process, which can help to ensure that the software is of high quality and meets the specified
requirements.
Disadvantages:





The Spiral Model is a complex methodology that requires significant expertise and experience to
implement effectively.
The Spiral Model can be time-consuming, as it involves multiple iterations of planning, risk
analysis, development, and testing
The Spiral Model can be more expensive than other software development methodologies, as it
requires a high degree of risk analysis, continuous feedback, and quality assurance.
The Spiral Model is less structured than other methodologies, such as Waterfall, which can make
it more challenging to manage and control the development process.
The Spiral Model requires a high degree of communication and collaboration among
stakeholders, which can be challenging in projects with large or distributed teams.
P2: How risk is managed in these lifecycles models
Waterfall model:
In the Waterfall Model, risk is managed by breaking down the software development process into
smaller, more manageable pieces. This allows for the identification and mitigation of risks early in the
development process, reducing the overall risk of the project. Additionally, the Waterfall Model
encourages thorough documentation and testing of the software, which helps to reduce the risk of the
project by ensuring that the software meets the customer's requirements.
V shaped model:
In the V-shaped Model, risk is managed by breaking down the software development process into
smaller, more manageable pieces. This allows for the identification and mitigation of risks early in the
development process, reducing the overall risk of the project. Additionally, the V-shaped Model
encourages thorough planning and design, which helps to reduce the risk of the project by ensuring that
the software meets the customer's requirements. Additionally, the V-shaped Model encourages
frequent testing and debugging of the software, which helps to reduce
Agile model:

customer to provide feedback and make changes to the project as needed. This helps to reduce the risk
of the project by ensuring that the customer's needs are being met
Spiral model:
The Spiral Model is a risk-driven software development process model. It is designed to manage risk by
breaking down the software development process into smaller, more manageable pieces. The model is
based on the idea that each iteration of the software development process should address a specific
risk. This allows for the identification and mitigation of risks early in the development process, reducing
the overall risk of the project.
M1: Discuss with an example why a particular lifecycle model is
selected for a development environment
Every company chooses a software development lifecycle based on the project requirements, size of the
team, the time given to complete the project and the complexity of the project.
For example, if a company is working on a project in which the requirements have already been finalized
and has a fixed timeline then they would most likely use the waterfall model. This is because the
waterfall model is a linear approach to project development and the team does not move on to the next
process of the development lifecycle until the previous step has been completed. Waterfall model also
provides clear documentation of every phase of the development process.
However, if a company is working on a project in which the requirements change over time then they
would most likely use an agile development methodology. Agile development is also good for those
projects that are not time bound. This development model also increases the communication and
collaboration with the client. The agile model is very flexible and the company is able to make sure that
the client requirements are met until the end of the project.
An Example of a project:
If a company is developing a web based remote working tool, they would most likely use the agile
development methodology. The look and feel of the website would be something that would keep
changing throughout the process and so a flexible software development lifecycle is best for such an
application. This kind of web based tool also requires a lot of testing to make sure that requirements are
met and the agile model is perfect for that since a lot of testing is done in this software development
lifecycle. It is also an iterative model so the product would be given in multiple iterations to get feedback
from the client rather than completing the whole website once and not meeting client requirements or
being adaptable to any change.
D1: Assess the merits of applying the Waterfall lifecycle model to a
large software development project
The Waterfall model is a direct and consecutive way to deal with programming improvement
that is ordinarily utilized in huge programming advancement projects. Its methodology includes
a progression of unmistakable stages that should be finished prior to continuing on toward the
following stage, including necessities gathering, plan, execution, testing, organization, and
support.
While the Cascade model has a few advantages, it likewise has a few potential downsides when
applied to enormous programming improvement projects. Here are a portion of the benefits
and difficulties of utilizing the Cascade model for enormous programming improvement
projects:
Merits:
Lucidity and consistency: The Cascade model gives clear and characterized moves toward
follow, which can assist with lessening disarray and guarantee that each step is entirely finished
prior to continuing on to the following. This can assist with making an anticipated improvement
interaction and undertaking timetable.
Documentation: Since the Cascade model requires documentation at each stage, it can assist
with making a total record of the improvement interaction. This can be useful for future upkeep
and updates.
Control: The Cascade model gives an organized and controlled improvement process, which can
be useful for enormous groups dealing with complex ventures.
Diminished risk: Since each stage is finished prior to continuing on toward the following, the
Cascade model can assist with decreasing the gamble of blunders and bugs in the eventual
outcome.
Challenges:
Rigidity: The Cascade model doesn't take into consideration much adaptability or
transformation to changing necessities or unanticipated issues that might emerge during the
advancement cycle. This can make it hard to change the venture extension or timetable on a
case by case basis.
Restricted client inclusion: The Cascade model doesn't give numerous open doors to client
contribution until the later transformative phases. This can bring about an eventual outcome
that may not address the client's issues or assumptions.
Long criticism circles: Since each stage should be finished prior to continuing on toward the
following, the Cascade model can bring about lengthy input circles between the improvement
group and the client. This can prompt deferrals and botched open doors for development.
Inflated cost: The Cascade model can be more costly than other advancement models since it
requires broad preparation and documentation at each stage.
rmous programming improvement projects, it may not generally be the best methodology. The
model's organized and controlled improvement interaction can be advantageous, however its
absence of adaptability and client association can challenge. Gauging the benefits and
difficulties
In general, while the Cascade model can be a suitable choice for eno of this model against the
particular necessities of your venture and group prior to pursuing a choice is significant.

are many extraordinary processes to the SDLC, but a commonplace one is the Waterfall version,
which entails the subsequent ranges:
Requirements gathering:step one within the SDLC is to collect requirements from
the client or quit-consumer. This entails defining the problem the software
program will solve, as well as any capability, functions, or constraints that need to be protected.
Design:the following step is to design the software program. This includes creating a excessivestage layout that defines the architecture and components of the gadget, in addition to a
detailed layout that specifies
how every issue will paintings and interact with different additives.
Implementation:The implementation segment includes writing the code
and constructing the software. that is in which the designs are was a working device,
and consists of tasks together with coding, unit checking out, and integration testing.
Testing: as soon as the software program is constructed, it wishes to be examined to make
certain it meets the requirements and is free of insects. This consists of trying out at
the unit stage, integration stage, and machine degree.
Deployment: once the software has been examined and accepted, it can be deployed to
the production surroundings. This involves putting in the software on the purchaser's or endperson's device, configuring it, and ensuring it runs successfully.
Maintenance:: After deployment, the software will want to be maintained
and updated as wanted. This consists of fixing insects, including new functions, and making
sure the software program continues to satisfy the needs of the consumer or quit-consumer.
it's vital to be aware that the SDLC is not a linear system - it is iterative and each level can
feed again into the previous degrees. for instance, if bugs are found at some point of checking
out, the design may want to be up to date, or if necessities change, the layout and
implementation may need to be adjusted.
P5 Undertake a software investigation to meet a business need
