I think another great example of process group within medical device are product complaints and change control that fall under monitoring and controlling process group. This continuous monitoring provides the project team insight into the heath of the project and identifies any areas requiring additional attention. According to PMBOK, in multiphase projects, this process group coordinates project phases in order to implement corrective and preventive actions to bring the project into compliance with project management plan. The key benefit of this process group is that project performance is measured and analyzed at regular intervals, appropriate events, or exception conditions to identify variances from the project management plan. The monitoring and controlling process group also involves: 1) controlling changes and recommending corrective or preventive action in anticipation of possible problems, 2) Monitoring the ongoing project activities against the project management plan and the project performance measurement baseline, and 3) Influencing the factors that could circumvent integrated change control or configuration management so only approved changes are implemented.
