How data is collected for metrics and measurements?

There are some ways for metrics and measurements for data

• Measurements are collected as per their definition at defined points as mentioned in Organization Metrics File
• Data is collected and compiled by using Project Summary, Help Desk, eRMS, Analysis Reports, Peer Review Analysis Reports etc
• Verification of the measurement data is done independently to check completeness, integrity, accuracy by SQA & SEG for the data that they provide to each other
• Once the data is collected will be assessed independently by QE
• Project may consider additional metrics to better manage their project
• Data should be available for use only by appropriate groups and personnel.

More about V & V.

Verification typically involves reviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklists, issues lists, walkthroughs, and inspection meetings.

Validation typically involves actual testing and takes place after verifications are completed.

• Both verification and validation use similar approaches i.e. reviews and testing

• Both validation and verification activities often run concurrently and may use portions of the same environment.
