Many years ago, TSSC introduced to my factory a visual measurement device referred to as a production activity log (PAL), also known to some as an hour-by-hour chart. Posted at the last operation of a particular process, the PAL provided an up-to-the-minute accounting and hourly summary of actual production quantity versus plan. The far right column of this report contained the most important information regarding the process health. If the actual rate in any hour deviated either high or low from the plan, the cell lead was accountable to report the problem and either remediate the cause or flag for additional assistance. Causes for deviations, either high or low, were innumerable: missing parts, missing operations, defective parts, broken fixtures, incorrect drawings to name just a few. As V.P. of manufacturing, I was accountable to review the PAL documents daily to assure overall process health. My job was to confirm that the area supervisors were able to address problems as they occurred. We didn’t call it Daily Management and we didn’t use the word “accountability, but it bore strong resemblances to both of these.
Shortly after implementing the PAL, I was chastised by TSSC’s consultant: “If you looked at the PAL,” he said, “you’d see that problems are not being fixed. If you don’t care, no one will waste their time reporting.” At the consultant’s insistence I began to visit and initial PAL’s every hour, an activity that was stressful for me, but also incredibly informative. As I paid closer attention, a few previously unnoticed accountabilities quickly became apparent:
So what does this have to do with the visual controls on huddle boards; the red and green dots that enable managers to assess the process health “at a glance”? Several things:
In 1995, we referred to the huddle board as a “production board,” and it provided a valuable periodic summary of quality, cost, and delivery, often capturing trends that would not have been apparent on daily charts; for example, delays occurring at the start of a shift or the start of week, or part shortages occurring at end of month. But, for breaking news, we went to the Gemba – the real place. And this is my concern about visual accountability as I often see it practiced today: It’s all about the huddle boards. When they are the only visual devices used by management, then the workplace becomes essentially invisible. (Incidentally, a quick read of David Mann’s book, will indicate that he intends huddle boards to be one of many visual devices, all of which must be functioning properly for the huddle boards to have any meaning.)
As part of your leader standard work, do you get out to the real place frequently to “sustain new behavior” or do you simply visit the huddle board and risk sustaining the old behavior?
Please send me your thoughts.
O.L.D.
By the way: The TSSC consultant who took me to the woodshed in 1995 has just been added to the agenda and will be speaking at our October 10-11 Northeast Lean Conference in Providence, Rhode Island. Bryant Sander’s topic will be... Daily Management : ) I can't wait and I really hope to see you there.
