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
