Criteria for Selecting Software Process Models - Computer Notes

The software process model framework is specific to the project. Thus, it is essential to select the software process model according to the software which is to be developed. The software project is considered efficient if the process model is selected according to the requirements. It is also essential to consider time and cost while choosing a process model as cost and/ or time constraints ...

Why should users be consulted when selecting the process model?

Software is developed for the users. Hence, the users should be consulted while selecting the process model. The comprehensibility of the project increases if users are involved in selecting the process model. It is possible that a user is aware of the requirements or has a rough idea of the requirements. It is also possible that the user wants the project to be developed in a sequential manner or an incremental manner (where a part is delivered to the user for use). Various other issues related to the user’s satisfaction are listed in Table.

What are the characteristics of a process model?

The basic characteristics required to select the process model are project type and associated risks, requirements of the project, and the users . One of the key features of selecting a process model is to understand the project in terms of size, complexity, funds available, and so on.

What is the possible way a user wants a project to be developed?

It is also possible that the user wants the project to be developed in a sequential manner or an incremental manner (where a part is delivered to the user for use).

Why is it important to select a process model?

No. Scarcity of resources. No. Yes. Yes. No. No. The most essential feature of any process model is to understand the requirements of the project. In case the requirements are not clearly defined by the user or poorly understood by the developer, the developed software leads to ineffective systems.

What is agile process?

The agile process model encourages continuous iterations of development and testing. Each incremental part is developed over an iteration, and each iteration is designed to be small and manageable so it can be completed within a few weeks.

Why is the RAD model important?

The RAD model accommodates changing requirements, reduces development time, and increases the reusability of components. But it can be complex to manage. Therefore, the RAD model is great for systems that need to be produced in a short time and have known requirements.

What is incremental development?

Incremental development is based on developing an initial implementation, exposing it to user feedback, and evolving it through new versions. The process’ activities are interwoven by feedback.

What is the goal of software process model?

The goal of a software process model is to provide guidance for controlling and coordinating the tasks to achieve the end product and objectives as effectively as possible.

When should waterfall models be used?

The waterfall model has a rigid structure, so it should be used in cases where the requirements are understood completely and unlikely to radically change.

Do each of the phases of a project need to be approved before the next phase begins?

Each of these phases produces one or more documents that need to be approved before the next phase begins. However, in practice, these phases are very likely to overlap and may feed information to one another.

Do complex projects have clear requirements?

Complex projects may not have clear requirements. The requirements may change often, and the cost of delay is high. Ask yourself if the project requires constant monitoring or feedback from the client.

Types of Software Development Cycle (SDLC) Models

The most common SDLC models include V Model, Waterfall, Spiral Model, Incremental Model, Scrum, Kanban, XP, and RUP.

Agile Methodologies

Many companies have adopted Agile methodologies in their software development projects. Usually, Agile methodologies focus on constant communication, iterative development, and early customer feedback. This helps promote better improvement in the delivery of software products and services.


Choosing the right SDLC model is one of the key steps in delivering high-quality IT solutions for your organization. However, it is important to understand that one solution may not work in all businesses or scenarios. Some projects run well with the flexibility of iterative and agile models, while others benefit from a waterfall approach.

What is iterative development?

The iterative development model is a life cycle where the project is broken down into a large number of iterations, where iteration is a complete development loop resulting in a release of executable products, i.e. a subset of the final product under development, which grown from iteration to iteration yo become the final product. Rapid Application Development, agile development, And Rational Unified Process are the examples of Iterative development model.

What is RAD in product development?

RAD allows rapid change and development of the product. It allows early validation of technical risks and rapid response to changing customer requirements. In the RAD model, users get the early visibility of the product and can provide feedback on its design and can decide, based on the existing functionality, whether to proceed with the development or not, what functions need to be included in the next delivery of the product. Users can also decide whether to stop the project or not if it not delivering the expected results.

What is rapid application development?

Rapid Application Development is formally a parallel development of functions and subsequent integration. RAD model allows users in the development process to review the product.

What is system testing?

System Testing: It is used to test the system as a whole. it verifies the system or product against the specified requirements. Acceptance Testing: It is used to perform validation testing with respect to user need, requirements, and business process conducted to determine whether or not to accept the system.

What is the purpose of gathering user requirements?

Gather the user requirements where the small to large, all the requirements are noted properly to understand the product requirements from the user

What is component testing?

What is a V model?

V model is a framework that is used to describe the software development lifecycle activities from requirement specifications to maintenance. In the V model, testing activities are integrated into each phase of the software development life cycle.

How long does it take to develop an Agile project?

In general, at the heart of Agile are iterative development, intensive communication, and early customer feedback. Each Agile iteration usually takes several weeks and delivers a complete working software version. The models of this group put more focus on delivering a functioning part of the application quickly.

How are SDLC models structured?

All SDLC models can be structured into several groups depending on how they approach workflow organization – linearly or iteratively – and what kind of relationships are established between the development team and the customer. The types in the lower quadrants of the chart take the sequential flow.

What is SDLC in software development?

Software development life cycle (SDLC) models show the ways to navigate through the complex and demanding process of software building. A project’s quality, timeframes, budget, and ability to meet the stakeholders’ expectations largely depend on the chosen model.

How many SDLC models are there?

Today, there are more than 50 recognized SDLC models in use. None of them is perfect, and each brings its favorable aspects and disadvantages for a specific software development project or a team. According to our 32 years of experience in software development, we’ve chosen 8 most popular models to look into their essence and compare for core features.

What is incremental development?

The development process based on the Incremental model is split into several iterations (“Lego-style” modular software design is required!). New software modules are added in each iteration with no or little change in earlier added modules. The development process can go either sequentially or in parallel. Parallel development adds to the speed of delivery, while many repeated cycles of sequential development can make the project long and costly.

Why are frequent releases important in Agile?

Accordingly, frequent releases are characteristic to the Agile models. They also allow for continuous software improvement with easy fixes and changes, quick updates, and feature addition, and help to deliver applications that satisfy users’ needs better. However, the lack of detailed planning and openness to changes make it difficult to accurately estimate budget, time and people required for the project.

How long does XP last?

With Extreme Programming (XP), a typical iteration lasts 1-2 weeks. The model allows changes to be introduced even after the iteration’s launch if the team hasn’t started to work with the relevant software piece yet. Such flexibility significantly complicates the delivery of quality software. To mitigate the problem, XP requires the use of pair programming, test-driven development and test automation, continuous integration (CI), small releases, simple software design and prescribes to follow the coding standards.

What is interactive incremental model?

The interactive and incremental model is built on repetitions. This model does not require a full set of requirements to be started. In fact, the development usually starts with specifying and implementing just part of the software which can be tested and evaluated later on.

What is waterfall model?

The waterfall model is one of the oldest software development models. Though this model was the most popular ones a few years back, its use has subsided over time as new and better software models have been introduced. However, since all other models are based on the classical waterfall model, its significance can not be ignored.

What is feature based licensing?

In feature based licensing you, the software vendor, can control which features of your software the end user can and cannot use. The feature license can also be used to limit the number of times a specific feature of an application is used. A feature license model is in effect a subset of the metered license.

What is a license model?

If you write and distribute software, it will typically come with a license model attached to it. This may be a non-commercial license that relies on the end user complying with the license terms, as is the case with most open-source or freeware licenses. If you write software for fun and profit, it is more likely that you’ll rely a licensing engine to help enforce compliance with the specific license model and terms on which you sell your software.

What happens when you track license usage in a floating pool?

It is also useful to note that when you track license usage in a floating pool, if users try to check out a license but all licenses have been consumed, it creates a great sales opportunity for you as the vendor as it demonstrates that there is more demand for licenses.

Why are traditional software development methods not very efficient?

Traditional software development methods are not very efficient because with the slightest or rapid change in the requirements, you need to have a meeting to improve.

Is Agile a good model?

In my opinion the model selection strongly depends on the particular case. 'Agile' is quite good as well as 'waterfall' would be also usable. The size of the team and the nature of the project is a key, just as Ahmad said.

Is waterfall Agile or RAD?

As pointed by many of our friends, it is Agile, RAD, Waterfall methodologies are fine.   Every thing depends on size of software, team etc.  Overall and above, we should look into the environment under which project being undertaken.   Whatever the methodology we adopt, it boils down to skill, commitment levels of the developing team.   In one of the software development project, I experienced that a person with only an average academic record contributed much more than a person with excellent academic record.   His commitment and urge to contribute helped me to come with an excellent and useful software.


What Is The Software Process Model?

  • A software process model is a kind of an abstraction of the software development process. The models specify the stages and process the order.
