What are the steps of system design?

Categories. The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Design, Construct and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).

What is the purpose of system development?

Systems development is the art and science of creating man-made systems to satisfy predetermined needs. It is a problem-solving process where we bring to bear appropriate elements of mankind’s knowledge base to create new knowledge specific to the problem and, as a result, define a solution to the problem.
