Measurements are necessary to “keep score” ?. how can we determine if we are making improvements unless we have well defined and meaningful measurements ? Measurements must be simple, easy to understand and an accurate measure of the process ? Measurements should not be “corruptible” ? Time and First Pass Yield are the best measurements Static and Dynamic Cycle Times ? Cycle Times have specific start and stop times. ? Cycle Time is a basic measure of process effectiveness and a good indicator of the discipline and order within a process. ? One must differentiate between Static and Dynamic cycle time: ? Static Cycle Time (sCT) is a summary of past actions (history). It is a lagging indicator and is usually applied to processes that change slowly. ? Dynamic Cycle Time (dCT) is the present “pulse rate” of a process and, thus, a leading (predictive) indicator. Static Cycle Time Measurement ? Static cycle time is the historical measure of cycle time based on analysis of individual outputs of a process. ? Static cycle time is a lagging indicator because it reports results after pletion. Collect Data, Use Collected Data to Identify Where to Look Frequency of Occurrence What is happening here? Use high/low diagnostic analysis and especially here? Static Cycle Time Population of One A fabric manufacturing process which starts on June 12 and concludes on July 19 has a static cycle time of 37 days. Start June 12 Stop July 19 Static Cycle Time = 37 Days Static Cycle Time (For populations of more than one) ? One can average the cycle times of work actions pleted. For example: 30 shirts pleted during a specific time period had the following distribution: 4 pleted in 2 days 3 pleted in 7 days 8 pleted in 3 days 2 pleted in 8 days 7 pleted in 4 days 6 pleted in 9 days sCT= Static cycle time = (4X2)+(8X3)+(7X4)+(3X7)+(2X8)+(6X9) 30 sCT = days for that specific time period Dynamic Cycle Time (normal) Dynamic cycle time is the current processing time for a relatively high volume of activities where In Process inventory exists at both the beginning and end of the period. Dynamic Cycle Time = Actions in Process (AIP) Average Processing Speed NOTE: The period of time may be one day, one week, one month the shorter the time period the more instantaneous the cycle time measurement Dynamic Cycle Time ? Is a leading indicator ? dCT = AIP’s / Process Speed ? AIP’s and process speed can vary through measurement period ? Need parameter estimates Dynamic Cycle Time Example (All data is for a one month time period) Beginning garment inventory 4600 Ending garment inventory 3600 Garments out to stock 31500 An average garment
