  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.
