Rework Effort %

Rework Effort  metric is the ratio of Total Effort for Rework to Total Effort for Project. This metric is used to monitor the percentage effort spend on rework activities is kept as minimum as possible. This metric helps to derive the actual value of rework activities performed for project. It is measured in percentage (%) figure.

Rework Effort is calculated at overall project level.

How to calculate Rework Effort %:

 Total Effort for Rework Total Effort for Project Rework Effort % 25 PD 500 PD 5

Rework Effort % = (Total Effort for Rework / Total Effort for Project) * 100
= 25 / 500 *100
= 5 %

How to calculate Schedule Variation ?

Schedule Variation or Schedule Variance metric is the ratio of difference between the Actual End Date and Planned End Date to difference between Planned End Date and Planned Start Date for the project.
OR
Schedule variation or Schedule variance is the ratio of difference between Actual No. of Days and Estimated No. of Days to Estimated No. of Days.
This metric helps to reduce the schedule variance or schedule variation by tracking it from start to end of the project. It helps to reduce the overruns. It is calculated either at project or stage level. It is calculated when particular stage in the project is completed. This metric gives the variation in the estimated schedule.
How to calculate Schedule Variation :

 Planned Start Date Planned End Date Actual Start Date Actual End Date Actual No. of Days Estimated No. of Days Schedule Variation 07/01/2015 07/31/2015 07/02/2015 08/01/2015 32 31 3.22%

Schedule Variation= (Actual End Date - Planned End Date) / (Planned End Date- Planned Start) *100
= 1 / 31 *100
=3.22 %
OR

Schedule Variation= (Actual No. of Days -Estimated No. of Days) / (Estimated No. of Days) * 100
= (32-31) / 31 * 100
=3.22 %

Note: The date format used in 07/01/2015 is MM/DD/YYYY

How to calculate Test Case Execution Productivity ?

Test Case Execution Productivity or Test Execution Productivity is the ratio of Number of Test Steps/Test Cases executed to Total Effort for Test Execution. Effort spend is always measured in hours.

How to calculate to Test Case Execution Productivity (Test Steps/Person Hour):

Test Case Execution Productivity  = (Number of Test Steps executed) / (Effort for Test Execution)

 Test Case Name Number of Test Steps Efforts required to execute Test Steps Test Case Productivity TC01 15 0.5 40 TC02 70 1.5 TC03 75 1.25 TC04 25 1.25 TC05 55 1.5 Total 240 6

Test Case Execution Productivity = 240/ 6
= 40 Test Steps / Person Hour
Test Case Execution Productivity is measured in steps per hour.

How to calculate Test Case Execution Productivity (Test Case/Person Day):

Test Case Execution Productivity  = (Number of Test Cases executed) / (Effort for Test Execution)

 Resource Number of Test Cases Executed Efforts Spend per Resource Test Case Execution Productivity Associate 1 20 8 10 Associate 2 10 Associate 3 15 Associate 4 15 Associate 5 20 Total 80

Test Execution Productivity = 80/ 8
= 10 Test Cases/ Person Day
