Before the team of software technicians can cough up the general idea for any software, it is essential for the team to gather the business requirements in this very first phase. At this point, the prime focus of the stakeholders and project managers is to note the exact things needed from any software under consideration.Once these general questions are answered, a general outline is created for the software developers to focus on. This data is then analyzed to ensure its validity & any possibility for incorporation of the same. Lastly, a document for requirement specification is prepared which serves as a guideline for the next level of the software development process.
This is the next phase for the software development process. In this stage, the draft design is prepared for the software from the stage-1 requirement specifications. The system designs help in specifying the hardware as well as system requirements. It also helps with the definition of an overall system in software architecture.The design specifications for the system serve as the input for the following phase of the software development model. In this particular phase, test strategies are developed by the testers by mentioning things to test and the ways to check it.
After receiving the design documents for the software to be created, the work following the design stage is divided equally into various units and modules. This is the stage where actual coding begins. The main focus of the phase is the development of perfect codes by the developers. This particular phase is the longest in the entire protocol.
If you want to know what is software development; you can never skip understanding the testing stage. This particular stage is very crucial for the developers. If anything goes wrong in the testing stage or any error is noted in the codes, it can lead to the repetition of the coding process, and the cycle goes on till the completion of the same. In this stage, all variants of the functional testing such as integration testing, unit testing, system testing, acceptance testing, and non-functional testing are done.
After all the errors from coding are removed during the testing stage, the next step is termed as the deployment stage. The finalized code is implemented into the software and then deployed or delivered to the customers to be used. As the product is being given to potential customers, the first thing done to ensure that it works fine on a large scale is to go with beta testing. If there is any possibility for changes or there are possible bugs caught during implementation, it is immediately reported to the team that engineers its errors to work fine in real-time. Once the changes are implemented with all the bugs fixed, the final dispersal or deployment is set in motion.
