These requirements are translated into design. A code is produced as according to the design that is created which is according to the requirement. This is called the development phase of the lifecycle. After coding and development the testing verifies the deliverable of the implementation phase against requirements [3]. 2.2) what are the benefits of the Software development life cycle process? The main aim of the lifecycle process is to produce a product which would be cost efficient, effective and also up to the high standard. Once the application is created, the lifecycle determines the proper arrangement and decommissioning of the software once it becomes legacy [5]. The life cycle contains following stages:  Requirement gathering and analysis  Design  Implementation or coding  Testing  Deployment  Maintenance 2.3) Requirement gathering and analysis This phase is critical to the success of the project. In this phase the purpose of the software or system should be determined. This is the phase where you can set the requirements that the software needs to fulfil when it is completed. Hence this stage is the main focus of project managers and stakeholders. This phase involves more communication to get the detailed description from the managers and the stakeholders as to who is going to use the system? How will they use the system? What data
