The stages of 'The ______ Model' include Requirement Analysis & Definition: All possible requirements of the system to be developed are captured in this phase. Requirements are a set of functionalities and constraints that the end-user expects from the system. The requirements are gathered from the end-users by consultation, these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied. Finally, a Requirement Specification document is created which serves as a guideline for the next phase of the model. System & Software Design Before starting the actual coding, it is very important to understand what we are going to create and what it should look like? The requirement specifications from the first phase are studied in this phase and the system design is prepared. System Design helps in specifying the hardware and system requirements and also helps in defining overall system architecture. The system design specifications serve as input for the next phase of the model. Implementation & Unit Testing Page 11 of 31 Certificate in Software Product Engineering TCS Business Domain Academy On receiving system design documents, the work is divided into modules/units and actual coding is started.

Develop a Project Task List, consisting of the tasks that should be performed during the remaining phases of the project. Concurrent component engineering 1. Develop the components assigned to the cycle. Working components are typically developed concurrently by development teams working in parallel and are delivered as builds on a daily or weekly basis. The produced builds are immediately fed into an integration process. Testing and refactoring are ongoing processes during this activity. 2. Manage the project through continuous monitoring and control. Maintaining the team collaboration and keeping the cycle on the right track are the main concerns. 3. Prepare for final Q/A by developing system-level test plans and test cases. 4. Prepare for quality review by planning the review meetings to take place in the Quality Review phase. Review: 1. Conduct cycle review by holding facilitated customer focus group sessions. The result of the cycle is presented to the customers.
