project management : What are the metrics followed in project management?

Most metric sets deal with a variation of these attributes and are chosen to help project managers gain insight into their product (size, software quality, rework), process (rework,
software quality) and project (effort, schedule).

But below is a broader classification :-
Project Management Metrics

milestone metrics

• number of milestones
• number of proved requirements per milestone
• controlling level metrics

risk metrics

• probability of resources availability
• probability of the requirements validity
• risk indicators (long schedules, inadequate cost estimating,

excessive paperwork, error-prone modules, canceled projects, excessive schedule pressure, low quality, cost overruns, creeping user requirements, excessive time to market, unused or unusable software, unanticipated acceptance criteria, hidden errors)
 

• application risk metrics
• walkthrough metrics
• traceability metrics
• variance metrics

controlling metrics

• size of control elements
• structure of control elements
• documentation level
•  tool application level                

management database metrics

• data quality metrics
• management data complexity
• data handling level (performance metrics)
• visualization level
• safety and security metrics

Quality Management Metrics

customer satisfaction metrics

• characteristics size metrics
• characteristics structure metrics
• empirical evaluation metrics
• data presentation metrics

review metrics

• number of reviews in the process
• review level metrics
• review dependence metrics
• review structure metrics
• review resources metrics

productivity metrics

• actual vs. Planned metrics
• performance metrics
• productivity vs. Quality metrics

efficiency metrics

• √ time behavior metrics
• √ resources behavior metrics
