Take a power saw. A power saw will allow me to cut boards in less time with less effort on my part as compared to a hand saw. But the power saw will not prevent me from cutting a board short. I have to understand what the board is for, how long it has to be, and the angle of the cut. If not I will waste a lot of time and lumber trying to make one cut.
To improve a process you can follow the DMAIC model.
- Define - define the problem. "There are too many errors or mistakes."
- Measure - How many times do we perform rework? How many widgets out of every hundred is flawed?
- Analyze - analyze the data to see what the root cause of the problem is. Don't look to address symptoms, find the driver for the problem.
- Improve - now that you have your root cause, attack it and see what can be done to eliminate it by reorganizing the steps, workflow or staff across a process or looking at automation of specific steps through technology.
- Control - once you have improved a process keep an eye on any deviations so that you can correct them quickly before they become major problems.
