Transcript of Process Improvement

Process Improvement by NIH IT Step 1: Review Review the process, determine the deliverable(s), goals of the process, participants / customers Create a flow chart of the current process Visualization Input Ask for input about issues from the individuals who are participating in the process Materials review the input / output material of the process (rules, guidelines, descriptions, standards) and look for ambiguous statements and possible confusion source Step 4: Examine Review the process, collect and write down facts, assumptions, questions and simplify by eliminating waste:
redundancy
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
unnecessary complexity
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
Quality: 95%
Lead Time: 1w Taks 3 Cycle Time: 1h
Quality: 100%
Lead Time: 2d Taks 4 Cycle Tiem: 3h
Quality: 80%
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
Quality: 100%
Lead Time: 0
