a. Gather individual estimations: For all activities in the process, ask the process executioners for their estimation on the required times. Do this individually with and repeat this exercise with minimum of 5 persons in order to have comparable data.

b. Workshop to validate estimations and determine need for measurements:

i. Input: individual estimations
ii. Participants: process owners, process executioners
iii. Procedure:

1. Validate (variation of) individual estimations
2. Determine need and approach for measurements

c. Gather measurements: There are different ways of getting measurements. The following ways can be applied alternatively or simultaneously:

i. Utilize loggings (timestamps) registered in the supporting IT systems of the process activity.
ii. Perform a DILO (Day In Life Of) by following the process and register the time utilization.
iii. Use check sheets to register an employee’s time utilization.

d. Workshop to validate measurements:

i. Input: measurements
ii. Participants: process owners
iii. Procedure: Validate measurements

e. Document performance data in process flow diagram

Input :
• individual estimations and measurements
• Process flow diagram 

Output :
• Process flow diagram – performance times included
