Transcript of Process Improvement
loops - what are the route cause of the loops
wait for multiple approval
unnecessary steps which does not lead to the process goals and deliverable
environmental waste (network, file location... etc) Step 5: Rework Discuss the facts, assumptions and questions come up then provide suggestions of rework the process Step 6: Validate Review if the deliverable is the same as it was of the original process by involving the business Step 7: Take ownership Assign one owner to the process who will be responsible for executing the process and makes sure the "rules" are followed.
Communicate the change! Step 2: Collect Step 3: Measure Questions? Core team:
Ferenc Pajor, Ferenc Dulovics, Sandor Toth
János Szép, László Szilágyi Example customer Taks 1 Taks 2 Cycle Time: 5h
Lead Time: 1w Taks 3 Cycle Time: 1h
Lead Time: 2d Taks 4 Cycle Tiem: 3h
Lead Time: 1w need value Cycle time (CT) of the process: 1h + 5h + 1h + 3h = 10h
Quality of the process: 100% x 95% x 100%x 80% = 76%
Total Lead Time LT: 0 + 8d + 2d + 8d = 18d = 144h (1d = 8h)
Value Added CT / LT = 10h / 144h = 6.94% Summary How to measure?
Using Value Stream Mapping What is Value Stream?
A series of steps that must be performed in the proper sequence to create value for a customer Definitions:
Quality of the process / task: percentage of first run success
Cycle time: time to complete a step / task
Lead time: delay / wait between steps / tasks Cycle Time: 1h
Lead Time: 0
