Stages of Application Development Models

1. Requirements analysis

   • tasks to be carried out
     • In this phase you are gathering information about the application that the client wants, or needs. You are investigating what is currently in place and developing an idea of what your clients wants.
   • Documentation to be produced
     • At the end of this phase you will produce a requirements analysis, which is presented to the client, who needs to agree with it before you can move on to the next phase.
   • people involved
     • stakeholders
     • company manger or care holder

2. Design

   • This testing allows for errors to be corrected and the product to be refined.
   • coding team or software group

4. Testing

   • Testing takes place both throughout the product’s implementation, and once it is believed to be complete.
   • When the developer is satisfied with the application, it is given to the client or end user to compare with their original requirements
   • by the producers of the project or testing crew.

5. Deployment

   • If the product is to be accepted, he handover of the product is arranged with the client.
   • the project team
   • company manager

6. Maintenance

   • All applications require maintenance, whether it is to correct errors, improve the performance, or adapt the application for new requirements.
   • Maintenance needs planning and agreement with the client
   • Will be done by the maintenance group of the project
