| description | According to the lean manufacturing philosophy, productivity can be boosted via work and time measurement
techniques by establishing suitable standard time and work methods. Standard is a level or grade that can be used as a measure
for comparative evaluation as a benchmark. It is developed and documented for many evaluations. For the case study, a standard
time was developed for the changeover process in die bond, which is a process in the semiconductor company. The standard
time was developed for the new improved work elements of changeover process in the company. The work elements in the
changeover process were first identified and established. Normal time, a value needed to calculate standard time was obtained by
two work measurements namely stopwatch time study and BasicMOST. The non-value-added activities and their respective time
in the changeover was identified via the synergy of data from both work measurements with the integration of both quantitative,
comparison of normal time and qualitative analysis. In a flow process chart 7 out of 18 work elements were classified as transport
activity, which was taken as non-value-added activity, and these took up 39 percent of the changeover time. A total of 7.56
seconds was then excluded from the standard time. The standard time was calculated to be 22.91 minutes using BasicMOST.
Since there was only a minor difference in times, less than 27.84 seconds from BasicMOST, the standard time was based on
BasicMOST, and the improved work procedures have been validated as effective. |
