The process measurements selected need to be
appropriate for the capability and maturity of the
processes being measured. Immature processes are not
capable of supporting sophisticated measurements,
metrics and measurement methods. There are four types
of metrics that can be used to measure the capability and
performance of processes:
■ Progress: milestones and deliverables in the capability
of the process
■ Compliance: compliance of the process to governance
requirements, regulatory requirements and compliance
of people to the use of the process.
■ Effectiveness: the accuracy and correctness of the
process and its ability to deliver the ‘right result’
■ Efficiency: the productivity of the process, its speed,
throughput and resource utilization.
