There are generally four stages of custom software development: feasibility and requirements gathering, design, development and testing, and deployment. The first two stages, feasibility and requirements gathering, usually happen simultaneously. They’re when we understand what the customer wants their new software system to do and how they want it to work.
The next stage is design. In this stage we put together a detailed plan for the system that’s been agreed on with the customer so far, based on our understanding of what they want their new approach to do or how they want it to work. The fourth stage is deployment, when we set up or install the system in its final location or make it available online as an internet application.
