There are various defined and designed approaches for software development that are used during the software development process. These approaches are also called "software development process models" (eg Waterfall model, incremental model, V model, iterative model, RAD model, Agile model, spiral model, prototype model, etc.). Each process model follows a particular life cycle to ensure success in the custom software development process.
Software life cycle models describe the phases of the software cycle and the order in which these phases are executed. Each phase produces deliverables required by the next phase of the life cycle. The requirements are translated into design. The code is produced according to the design called development phase. After coding and development, the tests verify the deliverability of the implementation phase against the requirements. The test team follows the Software Test Life Cycle (STLC) which is similar to the development cycle followed by the development team.
There are six phases in each software development life cycle model:
- Gather and analysis of needs
- Implementation or coding
1. Gather and Analysis of Needs and Requirements
The needs of the company are gathered in this phase. This phase is the main objective of project managers and stakeholders. Meetings with managers, stakeholders and users are held to determine requirements such as; Who will use the system? How will they use the system? What data must be entered into the system? What data should be generated by the system? These are general questions that are answered during a requirements gathering phase. After the collection of requirements, these requirements are analyzed for their validity and the possibility of incorporating the requirements into the system to be developed is also studied.
Finally, a requirements specification document is created, which serves as a guide for the next phase of the model. The test team follows the software test life cycle and begins the test planning phase after the requirements analysis.
In this phase, the system and software design is prepared from the requirements specifications that were studied in the first phase. System design helps specify hardware and system requirements and also helps define the overall architecture of the system. The system design specifications serve as input for the next phase of the model.
In this phase, the testers at mobile app development company in India & UAE develops the test strategy, where they mention what to test and how to test.
3. Implementation or Coding
Upon receiving the system design documents, the job is divided into modules / units and the actual coding is started. Since, in this phase, the code is produced, it is the main objective of the developer. This is the longest phase of the software development cycle.
Once the code is developed, it is tested against the requirements to ensure that the product actually meets the needs and requirements addressed and collected during the requirements phase. During this phase, all types of functional tests such as unit tests, integration tests, system tests, acceptance tests are performed as well as non-functional tests.
After a successful test, the product is delivered / deployed to the customer for use.
As soon as the product is given to customers, they will first do the beta test. If changes are needed or if bugs are detected, they report them to the engineering team. Once these changes have been made or the bugs fixed, the final deployment will take place.
Once customers begin to use the developed system, the real problems arise and need to be solved from time to time. This process where care has to be taken for the product developed and it is called as maintenance.
