  5. Testing: It is vital to test every component of the software to prevent any possible bugs. Testing helps in knowing the end capacity of the software in real business conditions that may affect its costs in long term testing.
  6. Software size: The software development costing is directly proportional to the size of the software and its user base. Its size is defined by the number of screens/pages it has and the size of the user base is defined by the number of end-users it is expected to adopt.

  5. Software testing stage: The most crucial stage where software testers check code quality and performance ensuring smooth software development & deployment.
  6. Deployment: The output of this stage is a functional, stable software meeting the defined quality & functional parameters. In simple projects, this is like deploying the code onto a web server while in larger projects , this could involve integration with different systems.
