Top 10 Software Development Process Models

Every software has its own functionalities, features, objectives, and goals which set them apart from one another. In addition to that, it is essential to know that every software is a combination of smaller modules that can be discovered in every stage of project development. 

To achieve basic objectives and goals regarding software projects, Custom Software development firms use different software development process models. These models help software developers to determine the exact order in which the development should commence. In this article, we have demonstrated the top 10 software development process models, so without further ado, let’s dive straight into it.

1. Waterfall Model

Everyone calls it a classic software development process model which is mainly used in government projects where programmers perform code testing only after the completion of the entire project. However, this leads to a serious concern as bugs in the codes can only be identified at the end of the project. Here are some interesting facts about Waterfall Model:

  • This model consumes more time compared to other SDPMs
  • Expensive
  • Only suited to develop small projects
  • Mother of all Models, Linear Sequential Model and Classic Life Cycle Model are other famous names for Waterfall Model

2. Agile Model

Software coders consider the Agile Model as the best alternative software development process model for Waterfall Model. It is widely preferred SPDMs. This model enables developers to reassess and change software plans and designs. “Customer satisfaction in each phase of the project” is the prime concern of this model. Hence, it breaks down the entire project into separate iterations.

Every part of the project includes employees associated with the process of analysis, planning, design, unit testing, coding, requirement gathering, and acceptance testing. This model allows developers to display a demo of the feature to the client which leads to satisfying them in every stage of development.

3. V Model

Moving on to the next model, V Model. Here, V stands for Verification and Validation. Some organization employs this model which overlay the roles of developers and software testers. Assigning roles to the respective team member( developer, tester,), this model ensures the parallel running of software development and testing.

The above-mentioned figure shows the graphical representation of the V model in which you can see superimposing of developers’ and testers’ lifecycle. The verification phase of this model provides you with information on whether you are developing the product in the right manner or not. It also tells you about the recent specification of the clients that need to be justified.

Validation includes mainly two criteria which are as follow:

  • The first one makes sure you are building the right product
  • The second one ensures your software meets clients specifications.

4. Incremental Model

Many of the elements of the Incremental model are similar to the Waterfall model. This model uses these elements in an iterative fashion. There will be multiple increment phases up until the completion of the project.

The first increment is all about the actual product. After each increment phase, the developer will be upgrading or modifying the software as per client requirements. The next increment phase is for applying changes suggested by the clients, this cycle continues until you finish developing the product that is ready to be released.

5. RAD Model

RAD model is known as the rapid application development model which is also identified as one type of incremental model. This model enables developers to break down the entire project into small tasks by the simultaneous building of functions and components.

Each task is coded and completed within the given time frame and delivered to the client. This results in getting constructive feedback from the client-side for that specific mini task.

6. Spiral Model

Labelled as an association of waterfall and iterative models, the Spiral Model starts with a little arrangement of necessities that are thought about at each phase of software development to guarantee their ideal coordination. Each period of a spiral model is started by the design objective of your customer, finishing with a customer audit. 

The word Spiral is adept for this model as the group of software developers chipping away at an undertaking add functionalities to the necessities in the example of expanding spirals till such time the whole application is prepared to continue on to the creation stage. 

Adept for huge and medium-risk projects, a spiral model can be utilized for projects which demand regular deliveries. Most appropriate to projects which have obscure or complex details, this model assists developers with making changes to the code at any point in time.

7. Iterative Model

In like manner speech, the word iterative means repetitive. The same is the situation with software design and development. In this model, the mammoth application that ought to be formed is isolated into more modest modules of the software. 

Every single module turns into the subject for additional enhancements when it goes through every one of the periods of software development, viz. prerequisite, analysis, design, execution, and code testing. This load of stages is rehashed in a sequential request till such time the end result is adequate.

8. Prototype Model

As the name suggests, the Prototype model includes the designing and development of primary codes. With this model, developers do not have to dig deep for input and output features. Labeled as a software working model with a considerable amount of functionalities, this model enables developers to create quick working programs.

Making a prototype that can be discarded, coders who follow this model can more readily understand their customer’s prerequisites. The prototype once showed to your customer permits him to get the “specific feel” of the framework. Ideal for enormous and muddled enterprises, this model discovers its place in frameworks, which don’t require manual interaction to determine project necessities.

9. Big-Bang Model

Big-Bang Model is meant to churn out tiny projects. It is a simple model and does not involve any rigid process. One would require minimum efforts to execute this model. Understanding the time, budget, and staff required to accomplish the project, the final outcome is the product of software code that may not meet clients’ specific requirements.

10. Code and Fix Model

As shown in the earlier stage of the Big-Bang Model, the Code and Fix Model rely on identifying the product that should be verified before rolling out in the market. This model is especially for developers and software testers who work simultaneously with each other.

 In this model, the team of testers finds bugs and sends them to developers. The developers will modify the codes to eliminate bugs. The process requires less planning than other SDPMs that is why this model is suited best for less complex projects.
