![]() ![]() The iterative model means, it is a particular implementation of a software development life cycle that focuses on an initial, simplified implementation, which then progressively gains more complexity and a broader feature is set until the final system is complete. The linear sequential model means it is a systematic sequential approach of software development that begins at the system level and progresses through analysis, design, coding, testing, and support. Here, it is not necessary to wait for the completion of all modules of the software for the release. This approach will allow us in incremental releases of the product. This spiral model is the combination of the iterative development process and the sequential linear development process. This model will help in projects where the requirements keep on changing. It is the way of building and testing the software by splitting and adding the requirement in incremental order. In the upcoming sections, we can discuss more on the Agile workflow. Agile is defined as the sprint-based software development life cycle. #2) Agile ModelĪn agile workflow is an advanced approach to the software development process, which is used in the majority of companies. We will discuss more on the waterfall model in this tutorial. When the project is very simple and there are no further requirements changes, we will follow this approach. It is the sequential way of developing software. #1) Waterfall ModelĪs discussed earlier, the waterfall model is the first introduced software development life cycle. ![]() Let us see a brief introduction to the types of SDLC used in the software development process. It makes the communication line between the client and the development team and creates the roles and responsibilities for each of them. It also helps in scheduling and estimating the tasks. It helps the team management to define and evaluate the objectives and requirements. It is somewhat like a user guide to the team members to follow all the steps to develop and deliver the quality product. It provides the scope and deadline for each phase in SDLC. It provides a certain level of control and defines the roles and responsibilities of the team members. SDLC is required to manage the project in a structured way. Why software development life cycle is required? Based on the necessity and compatibility of the business requirement, we will choose the best model to develop the software application. Other SDLC includes the spiral model, V and V model, Prototype model. Agile is derived from other software development life cycle. The agile model is the latest and advanced one. The waterfall model is one of the SDLC types and it is an old process of developing software. Based on the requirement, an appropriate life cycle is selected. For this, we select from different types of software development life cycles in different companies. It is a step by step procedure to develop the software systematically. What Is The Software Development Life Cycle? It is a method of project management that is represented by serial stages and a fixed plan of work.īefore discussing the Waterfall workflow and Agile workflow, let us have a look into the Software Development Life Cycle definition and its requirements. This same illustration applies to the concept of project management when it comes to the waterfall model. The waterfall model is a linear sequential model in which the progress flows majorly in one direction downwards through the phases of requirement gathering, analysis, design, development, testing, deployment, and maintenance. Similarly, the word waterfall denotes a vertical flow of water or the flow of water through a series of steep drops. In simple English, Agile means ‘able to move quickly and easily’ and hence that is what it means when it comes to the Agile development methodology.Īgile is a method of project management that is represented by splitting the tasks into shorter segments of work with frequent reviews and adaptation of plans.
