The maintainability of a system can be considered to be a measure to determine how easily the repair actions can be performed. When we say repair, we need to discuss the following:
The ease of fixing issues in a deployed system (if any)
Improvements in the system to match the changing business needs
Coping with infrastructure changes in the deployment environment

This is one area that jBPM excels in; as we have already discussed in earlier chapters, jBPM provides a full-fledged modeling, simulation, and deployment tooling environment. The actors, from this perspective, business analysts and developers, can use the tooling to model, simulate, test, and deploy the process changes.
