On Time Delivery Index (%)

1.  

# Implementations delivered

2.  

    # Migrations delivered

% implementations competed on the Implementation end date (Planned)

% migrations competed on the Migration end date (Planned)

Project Monitoring and Control

Schedule Variance (%)

Planned # of days to complete implementation

Planned # of days to complete migration

% variance between the planned and actual schedule for implementation

% variance between the planned and actual schedule for migration

Project Monitoring and Control

Size Variance (%)

Estimated Size

% variance between the planned and actual size for implementation/migration

Project Monitoring and Control

Requirement Stability Index (%)

(1- (# changed requirements + # deleted + # added/# initial requirements))

Provides perceptibility to the scale and effect of requirements changes.

Design

Design Review Effectiveness (%)

(#Design Review Defects / (Design Review Defects + Code Review Defects + Unit Testing Defects + QA Testing Defects + User Acceptance Testing )) *100

Design

Code Review Effectiveness (%)

(Code Review Defects / (Code Review Defects + Unit Testing Defects + QA Testing Defects + User Acceptance Testing))*100

Project Monitoring and Control

Effort Variance (%)

Planned Effort

% variance between the planned and actual effort for implementation/migration

Project Monitoring and Control

Resource Utilization (%)

(Actual Effort / Actual Variance Effort)*100

Testing

Test Coverage (%)

# Test Cases Executed/# Test Cases Written

Gives an understand of what is being tested and how much is being tested

Testing
