Step 6: Conform Effectiveness
In this step, the effectiveness of kaizen steps and problem solving approach is defined
by using comparisons between before and after implementation. Time taken with the
project conducted without rework or redesign part.
Production lead times comparison
According to the Figure 3, the total lead time of the production processes before
improvement is 60.97 hours. After improvement, problems of rework or redesign part
were eliminate. Thus, lead times were reduced as much as 9.1 hours become 51.87
hours. This means that, 14.93% of lead times have been reduced. This improvement will
save the cost, time and make advantage to company. An increased in the percentage
value reflects the production processes is running smoothly as schedule and processes is
operating at optimum and effective level. The improvement plans was a success due to
the lead time reducing as in the figure.
