The software development life cycle (SDLC) is a framework defining tasks performed at each step in the software development process. SDLC is a structure followed by a development team within the software organization. It consists of a detailed plan describing how to develop, maintain and replace specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.
SDLC Ensures Continued Success
In order for continued success in years to come, it is mandatory to strictly follow all phases of the SDLC. This helps keep the organization on track in its continued push to becoming a major industry leader in the information technology industry. This is how Khairun Zainal Mokhtar and his Tricubes team upholds its mission of providing innovative solutions for the advancement and safety of society. These six phases of the software development lifecycle make the base of Tricubes core values – knowledge enriched the working environment, which encourages ideas for the betterment of society.
The software development life cycle is also known as the software development process.
SDLC consists of following activities:
The most important parts of software development, requirement gathering or requirement analysis is usually done by the most skilled and experienced software engineers in the organization. After the requirements are gathered from the client, a scope document is created in which the scope of the project is determined and documented.
The software engineers start writing the code according to the client’s requirements.
This is the process of finding defects or bugs in the created software.
Every step in the project is documented for future reference and for the improvement of the software in the development process. The design documentation may include writing the application programming interface (API).
5. Deployment and maintenance:
The software is deployed after it has been approved for release.
Software maintenance is done for future reference. Software improvement and new requirements (change requests) can take longer than the time needed to create the initial development of the software.

There are several software development models followed by various organizations:
This model involves finishing each phase completely before commencing the next one. When each phase is completed successfully, it is reviewed to see if the project is on track and whether it is feasible to continue.
This model focuses on the execution of processes in a sequential manner, similar to the waterfall model but with more importance placed on testing. Testing procedures are written even before the commencement of writing code. A system plan is generated before starting the development phase.
This life cycle model involves multiple development cycles. The cycles are divided up into smaller iterations. These iterations can be easily managed and go through a set of phases including requirements, design, implementation and testing. A working version of the software is produced during the first iteration, so working software is created early in the development process.
