The Stages And Processes Involved In The Software Development Life Cycle
Introduction
The software development life cycle (SDLC) is a blueprint that defines the stages involved in the development of software. SDLC can be defined as a structure imposed on the development of software. It provides a set of steps and guidelines to be followed by each team member who is involved in the project, along with their responsibilities.
Planning
Planning is the first step in the software development life cycle. It is a process of defining the scope and objectives of a project.
In this stage, you need to identify goals and objectives, define requirements, create a high-level design, identify risks and mitigation plans for them, etc.
For example:
-
Establishing your goal - what will be achieved by completing this project? For example: "To create an application that allows users to manage their data" or "To develop an online store where customers can purchase products".
-
Identifying requirements - what steps should be taken or things should be done so that these goals are met successfully? For example, You’ll need an online store where products are available on sale; each user must have his own personal account; orders can only be made by registered customers; etc.
Analysis
Analysis
Analysis is the first step in the Software Development Life Cycle and it involves evaluating a problem or a requirement and determining what requirements you need to develop a solution. Analysis can also be used to define business processes, analyze design elements and analyze code. A common misconception about analysis is that it’s synonymous with requirements analysis. While both play an important role in defining software functionality, they differ in several ways:
-
Requirements analysis is a systematic process for gathering information about users' needs and wants, who will use the system, how they'll interact with it, what features are needed etc. (typically from end users). This data will be used by other phases within SDLC such as design & coding etc.
Design
The design phase is where you start to bring your idea to life. This process involves taking your requirements (what the user wants to achieve) and turning them into a solution that’s easy for a computer to interpret.
Modelling
Modelling is the process of creating a conceptual representation of the software. Models are created to help understand the system and its requirements and can be used to communicate the system and its requirements. Models can also be used to verify that what you have planned matches what you have started building.
Modelling is an iterative process where models are continually refined until they are considered “good enough” or stable enough to continue with software development activities (e.g., code generation).
Construction
In Construction, the main goal is to produce a unit of software that can be tested and analyzed by an independent party. This process begins with writing code (the actual programming language) and ends with testing it through various methods, such as manual and automated testing or analyzing the running performance for errors. The last step in this stage is releasing your product for use by your client or customers!
Integration
Integration is the process of combining the different components of your system. It can be as simple as integrating a few pages or it could involve integrating dozens of applications. In any case, integration is an important step in the SDLC because it ensures that all aspects of your application work together as intended and meet business requirements.
Testing
Testing is the process of making sure that the software does what it is supposed to do. Testing is an important part of the software development life cycle.
Testing, like all stages in SDLC, should be ongoing and not a one-time event. Testing can be done manually or automatically by using test case creator tools which generate test cases for each feature or function. Test cases are created by developers and testers who work together to formulate them based on requirements specifications and design documents prepared by architects/designers during earlier stages of SDLC.
Deployment
Deployment is the last phase of the software development life cycle. Deployment is the process of making the software live, or available to users. Deployment includes:
-
Testing
-
Installation on machines
-
Configuration and customization

The process includes planning, analysis, design, construction, testing and deployment. The lifecycle is iterative. It is a process that is followed by software engineers to develop software.
Conclusion
We hope that you have found the information covered here useful. As we mentioned earlier, Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality software. The SDLC aims to produce high-quality software that meets or exceeds customer expectations, and reaches completion within times and cost estimates.
