  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.

Why should a business get their own custom software?

  2. Feasibility: Check if the software solution is solving the end user problems, meeting expected requirements & resources for executing as well as delivering the project.
  3. Design & Prototyping: Design & developer team work together to figure out the software design & prototype helping in envisioning the functionality & the first ever workable version of the product.
  4. Software Development Stages: At this stage, developers need to confirm things with product owners & testers ensuring you have a working feature to share with the customers. You start seeing something resembling the final product.
  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.
