Table 5.8 Strategies for increasing speed
Determine present levels * Speed
Bottleneck processes
* Downtime, frequency of stoppages
* Conditions producing defects
Check differences between What are the specifications?
specification and present situation 0 Difference between standard speed
and present speed
Difference in speeds for different products
Investigate past problems e Has the speed ever been increased?
