8 Types Of Software Development Models-How to choose the best software development model for your project?

Developing new software is not an easy task. Making sure the project meets all of its deadlines, stays on budget, and delivers high-quality work can be daunting, to say the least! But there are some models that help make this process easier than others- like SDLC (Software Development Life Cycle). 

What is SDLC Model?

The software development life cycle model is used in project management to define various stages of software development. It is a detailed plan that describes how to develop, maintain, replace, and change or improve specific software. An SDLC model can literally make or break your project. A proper model should be chosen according to time constraints, budgeting needs, quality expectations from stakeholders.  

The life cycle defines a methodology for improving software quality and the development process as a whole.

In today’s world, there are more than 50 different models for software development to choose from. No model is perfect, and each one has its pros and cons depending on the needs of a given project or team. After 20 years in this industry, we have sifted through those 8 most popular software development life cycle models with an eye towards their core features so you can be successful now as well as tomorrow.

Knowing about the basic stages of software development is very crucial. So let’s explore them one by one to understand each of the SDLC models and figure out which one to choose to make our project successful.

Basic stages of SDLC 

Stage 1: Planning and Analysis

Each software development life cycle model begins with an analysis in which the process stakeholders discuss the requirements for the final product. The goal of this stage is to define the system requirements in detail. Moreover, it is necessary to ensure that all process participants understand the tasks and how each requirement can be implemented.

Stage 2: Creating Project Architecture

Developers usually design the architecture during the second phase of the software development life cycle. All of the technical questions that may arise during this stage are discussed by all stakeholders, including the customer.

Stage 3: Development and Programming

Following approval of the requirements, the process advances to the next stage – actual development. Programmers begin writing source code here, keeping previously defined requirements in mind. System administrators configure the software environment, while front-end programmers create the program’s user interface and the logic to communicate with the server.

Stage 4: Code Testing

Debugging occurs during the testing phase. All code flaws discovered during development are identified, documented, and returned to the developers for resolved and the software workflow has been stabilized.

Stage 5: Deployment

When the program is complete and free of critical flaws, it is time to make corrections. The testing procedure is repeated until all critical issues have been available to end-users. The tech support team will join after the new program version is released. This department provides user feedback, as well as consultation and support to users during exploitation. This phase also includes updating selected components to ensure that the software is up to date and secure.

SDLC Models

1. Waterfall Model

 The waterfall process is a method of software development that moves in an orderly cascade, with each stage having concrete deliverables and being strictly documented. Each stage has its own deliverables and documentation, with the next stage requiring completion before starting on it. Therefore, the software requirements cannot be re-evaluated at a later stage of development.

There is also no way to see or test the software until the final development stage is completed, resulting in high project risks and unpredictable project outcomes. As a result, testing is frequently rushed, and errors are costly to correct.

Use Cases

  • Small or medium-sized projects with well-defined, unchanging requirements.
  • Projects that make use of a well-known technology stack and tools.

2. Validation and Verification Model

The V-model (Validation and Verification Model) is a project management model that can produce high-quality work, but it becomes very costly and time-consuming in the process. 

The development phase of this methodology has its own set of limitations. The development mistakes are costly, and it’s not easy to identify them in the beginning. As seen in the waterfall model, requirements can be gathered in the beginning, but they cannot be changed later.

Use Cases

  • Projects in which failures and downtime are not considered acceptable.

3. Incremental and Iterative Model

The development process in the incremental model is like building a Lego structure.

Each iteration of work splits into smaller pieces, with new modules being added at each step without touching any previous ones. Software development can be done in either a parallel or sequential manner. Parallel development is quick and inexpensive, whereas sequential development is time-consuming and costly.

In the iterative model, the software transforms and grows in subsequent iterations. The number of these iterations adds up to previous ones, but the basic design remains unchanged throughout this process.

The project is delivered part by part with no need for specification from the start, as changes can be made to specifications during the development stages.

This SDLC model is a great way for customers to be involved with how their project goes because it often entails some small requirements amendments during the development process.

Use Cases

  • Large, mission-critical enterprise applications made up of loosely coupled components.

4. Spiral Model

One way to use the Spiral Model is by hiring experts in risk evaluation. The four essential activities in this cycle are planning, risk analysis, prototype creation, and customer feedback during review or exploration for previous tasks completed on the project.                     

It repeats itself as an extension on how long your project will take because each cycle has feedback from customers, which allows them to input into the review process so they can explore certain aspects while still providing their experiences with what would be needed to improve upon any flaws found within prototypes or products.

Use Cases

  • Projects that are both large and complex.
  • The introduction of a new service or product, as well as research and development activity.

5. Rational Unified Process Model

The rational unified process is a software development process that focuses on requirements gathering, prototyping, and defining quality standards in order to produce high-quality software.

This process can provide benefits such as ensuring good design, creating an organized process, and increasing productivity in software development.

Use Cases

  • Large and high-risk projects, particularly use-case-based development. 

6.  Agile Group

The Agile umbrella is small but mighty. It’s a group of models that provide fast and efficient solutions for the modern business world, focusing on customer feedback, strong communication with stakeholders as well as iterative development cycles to produce quality solutions in weeks. They are more concerned with detailed documentation than testing.

As there is no documented software description, identifying problems when maintenance is required takes longer. However, agile programs are constantly updated, changed, evolved, and improved. 

Also, when it comes to software development, it is wise to outsource the work as it is more convenient and cost-effective. 

Agile software development necessitates a much higher level of contribution from all the parties involved. As a result, one or both parties must make compromises in their traditional processes in order to adapt to the task at hand. This necessitates the use of an experienced software partner with whom you can successfully collaborate to develop customized software solutions based on your needs.

What’s the best way to develop software? 

There is no easy answer. Agile can be multifunctional but has its flaws because it doesn’t work for every customer, and there are too many variations between industries that have different needs when it comes to development timeframes. With so much information out on what constitutes a good model of SDLCs, you might feel like this world is getting more complicated instead of less!

Various models have been developed through SDLC evolution which reflects a variety in development expectations and needs that are appropriate for different businesses. Ultimately it’s not about finding one perfect model but rather determining what will work best with your company culture.
