Decomposition is where a problem is broken down in to smaller subproblems to simplify the process of solving a bigger problem.

Key stages

• Identifying and describing problems and processes
• Breaking down problems and processes into distinct steps
• Describing problems and processes in structured steps

Identifying and describing problems and processes

In this stage the problem is identified and problems and processes are described in detail.

Breaking down problems and processes into distinct steps

In this step the problem is broken down into distinct steps.

Describing problems and processes in structured steps

In this step the problem is structured into processes and structured steps.
