    Thanks

    In my case we measured time (in seconds & minutes). We measured the time it took one unit to complete the process. (3 minutes)
    Then we took time measures at each process step:
    Step 1 – 10 sec
    Step 2 – 1 min 30 sec
    Step 3 – 1 min
    Step 4 – 10 sec
    Step 5 – 10 sec
    When you look at steps 2 & 3 they are much larger times, we then broke down those steps into smaller steps amd measured them. This is where we found that in step 2 we are waiting 45 sec on each unit for the printer to print. We felt we had two options at this point: 1) Move printer to the next process step, so that by the time the unit reached step 3 the paper would have printed.(only two feet between steps) 2) Upgrade hardware.
    We have went with option 2 and now process step 2 time is 40 sec. 44% reduction in process time for that step.

    Jackie,
    I’m not sure if GDS used one but we require operational definitions of the measurement process as part of measure.  This ensures that everyone involved fully understands exactly what is being measured and how it is bounded.  For example, an operational definition for cycle time in this situation could be:
    Cycle time is defined as the length of time between the receipt of the request as indicated by the date/time stamp on the record of the previous process step completion and the completion the process step as indicated by the date/time stamp on the record.
    We’ve found this to be of benefit to us….
    Hope this helps…
    Best Regards,

    Bob,
    You have a good point, and Yes, we require that the projects operational definition be stated in measurable terms. As for the data collection we ensure that all involed understand the definition. We create a data collection plan, that states, WHO,What,How and When of the plan.

    GDS,
    Thanks!  Thought so but sometimes it’s worth mentioning the less flashy (nonstats) stuff that helps projects stay on track and promote clarity…  Sometimes they get lost in the shuffle….
    Have a great weekend!
    Best Regards,
