SDLC refers to a systematic process with a clear and defined process for creating high-quality software to meet customer expectations. Software Development Life Cycle is a set of various stages followed by a software developer to develop a project.
A Software product outsourcing company goes through the following stages of SDLC:
- Stage 1: Planning and Requirement analysis – All the relevant information is collected from the customer, sales department, market surveys to plan the project. Once the requirements are established, an investigation is done to check for the product's feasibility, and the SRS (Software Requirement Specification) document is prepared.
- Stage 2: Designing – The requirements based on the SRS document are used to implement software development. Building a product roadmap helps the development and the product teams to get a clear picture of the overall requirements.
- Stage 3: Developing – Software outsourcing companies follow the programming guidelines and adopt their development t process according to the project requirements. Various programming languages are used to create suitable software.
- Step 4: Testing – Testing is basically done at each and every step of the SDLC. Here the product defects are reported, tracked and fixed to prepare a top-notch product. All possible functionality errors are diagnosed and corrected before the final release of the software.
- Step 5: Deploying – The final tested product is released to be used. Normally the Software product outsourcing companies first release the software to a limited audience, and after the final feedbacks, it is released in full.
- Step 6: Maintenance – There is always a continuous requirement for innovation to help software to grow and develop as per the needs. Software outsourcing companies maintain and update the product when and where required.
Models of Software development life cycle
Following are the most popular models followed:
- Waterfall Model: Here, all the requirements are determined initially, and the development process is done in a definite sequence. There is no going back in this model, just like the movement of a waterfall.
- Iterative Model: This model enables the developer to divide the product into small chunks. Detailed programming is not required in this model, and once the iteration is completed, a product is verified and delivered.
- V-Shaped Model: The product moves from one phase to another immediately. Here development and testing go hand in hand. This model's highlight is that the testing starts at an early stage to rectify all the possible outcomes.
- Spiral Model: This model focuses more on risk analysis. Here the developers adopt elements of one or more models like a waterfall, incremental, and others.
- Agile Model:There is a high engagement level between the client and the developers under this model. This method focuses more on flexibility than on the requirements of the company.
Conclusion
A business needs to adopt an SDLC to transform the idea of software into reality. In addition to technical aspects, the process covers system development with better user experience and management policies.
