The software development life cycle (SDLC) provides an easy way to find out what stage the team is in, what resources are needed, and what the next step is.<\/p>\n\n

Traditionally, any SDLC has six phases in a life cycle which include requirement gathering, analysis, design, coding, testing, deployment, and maintenance. Several SDLC models are introduced based on how the team wants to move into every phase.<\/strong><\/p>\n\n

In this article, we will cover the most used, popular, and important SDLC models and discuss which one you should choose for your project.<\/strong><\/p>\n\n

1- Waterfall<\/strong><\/p>\n\n

Let us start with the oldest model of SDLC, the waterfall approach developed in\u00a01970 by Winston W. Royce; the<\/strong>\u00a0model uses a linear approach in which one step needs to be completed before moving to another.\u00a0<\/p>\n\n

This method is thoroughly documented and clearly defined with features for each stage of the software development life cycle. Once the software is fully developed only then it is tested against specified requirements and reworked.<\/p>\n\n

This model is easy to manage, but Software companies typically require more flexibility than the waterfall methodology offers. Once the stage is over, it is difficult to go back for revision, which makes it challenging to fix any problem. However, due to its structured approach, it remains a strong solution for some types of projects.<\/p>\n\n

2- Iterative<\/strong><\/p>\n\n

This methodology involves the waterfall model and\u00a0loops through it several times in small increments<\/strong>, each stage is divided into several mini-projects that can add value as the product progresses.\u00a0<\/p>\n\n

The Iterative approach can be implemented without the full list of requirements in the projects. A team\u00a0only requires functional part requirements.<\/strong>\u00a0The method goes through all phases of the SDLC, the process is repetitive and enables new product versions to be developed for each phase.\u00a0<\/p>\n\n

The main benefit of the Iterative model is that it creates an early working version of the project which allows making changes less expensive. The major drawback of this model is the need for repeated iterations. The method should be used carefully, otherwise, the resources for\u00a0unnecessary changes can be drained<\/strong>\u00a0easily.<\/p>\n\n

3- DevOps<\/strong><\/p>\n\n

DevOps is one of the latest SDLC methodologies and is adopted by many IT and software companies. As per the model, developers and organizational\u00a0teams operate in full collaboration<\/strong>, often as a team.\u00a0<\/p>\n\n

The benefits of this kind of approach are that it makes changes more flexible, thus reducing corporate risk and enabling the deployment of higher quality and more reliable software products. This model is quite expensive to implement as there are\u00a0limited DevOps expert developers available<\/strong>. Teams must have flexible resources to ensure an effective DevOps arrangement.<\/p>\n\n

4- V-Model<\/strong><\/p>\n\n

The V-shaped model of SDLC is a modification of the standard waterfall model. The\u00a0v-model has quite a strict approach,<\/strong>\u00a0with the next phase starting after the first phase. This model is also called Validation-Verification, as the test helps you to verify that all the requirements are fulfilled and that the team can move to another development phase for software.<\/p>\n\n

\u00a0When using a V-model you can\u2019t easily move a step back to fix or add anything. If you are not sure about the software\u2019s final functionality or if it has many features this model is not recommended as\u00a0it lacks flexibility and has higher risks<\/strong>.<\/p>\n\n

However, this approach can be a smart choice for projects where requirements are static and\u00a0specifically defined, and early testing is required<\/strong>.<\/p>\n\n

\u00a05- Spiral<\/strong><\/p>\n\n

The spiral model is a fusion of the SDLC model Iterative and Waterfall with a\u00a0significant focus on risk analysis<\/strong>. The entire software development process is divided into several small phases to be implemented by the teams.\u00a0The challenge with the spiral model is to recognize when is the right time to step into the next phase.<\/p>\n\n

The Spiral model looks appropriate for businesses that aren\u2019t sure about their requirements or projects that are\u00a0large, complicated, and expensive\u00a0<\/strong>since it helps development teams to build prototypes earlier and incorporate user feedback into the project early. This model can be quite expensive\u00a0for low and medium-risk projects.<\/strong><\/p>\n\n

\u00a0<\/div>\n\n

6- Agile<\/strong><\/p>\n\n

The Agile methodology, in particular, is one of the strongest approaches in software development. The Agile model involves\u00a0designing, developing, testing, deploying, and reviewing\u00a0<\/strong>software approaches.\u00a0<\/p>\n\n

This is a method that requires developers, management, and customer engagement for all ongoing processes. Agile is focused on ongoing cycles of production. Typically,\u00a0work is split into \u201csprints\u201d for two or four weeks<\/strong>, in which responsible teams respond to their customers\u2019 major needs and carry out their tests as they go.\u00a0<\/p>\n\n

One of its drawbacks is that it is challenging to determine resources and development costs due to a lack of defined requirements. Agile works well,\u00a0particularly for startups<\/strong>, where speed and flexibility are important.<\/p>\n\n

\u00a0<\/div>\n\n

7- Lean<\/strong><\/p>\n\n

The agile and lean strategies are interrelated as they all emphasize delivery speed and constant improvement. The Lean SDLC approach is focused on waste reduction throughout all stages,\u00a0including scheduling, expense, and scope<\/strong>. The methodology involves simply focusing on issues that can be done on time without multitasking.<\/p>\n\n

The lean\u00a0approach requires flexibility and a full revision\u00a0<\/strong>of the working processes and\u00a0its implementation cost is high<\/strong>. This approach is suitable for organizations with strict hardware requirements.<\/p>\n\n

8- Prototyping<\/strong><\/p>\n\n

In this methodology, the design team concentrates on producing an early model of the software or application. The prototype\u00a0working model won\u2019t have full functionality<\/strong>.<\/p>\n\n

They are not introduced in the market but are instead planned to be checked firsthand by prospective customers to\u00a0eliminate the problem before heading through development<\/strong>. This approach is best for emerging companies or new technologies.<\/p>\n\n

Conclusion<\/strong><\/p>\n\n

This is what SDLC methodologies are about in a nutshell. The development of a software method ideally suited for your project may rely on factors such as\u00a0timeline, cost, quality,\u00a0<\/strong>etc but keep in mind that one solution may not fit in every scenario or business.\u00a0<\/p>\n\n

Every method has its advantages and disadvantages; some projects are better carried out with a waterfall strategy, whereas others\u00a0may benefit from flexibility from agile or iterative models<\/strong>.<\/p>\n\n
