    Follow the process. It works. The measure phase will be critical (especially the process map). Unless you can speed up the machines, the process steps are the only place to improve throughput. Good Luck.

    Make sure you pareto chart the root causes of the defects to focus on the major hitters. You won’t be able to get rid of ALL defects (most likely), so focus your efforts on the ones that will make a major impact on the business.

    Good luck!

    The obvious place to start is with records. If you want to improve up time, then you need to know how much down time there is. Once you know how much down time there is the next question is “what are the reasons for the down time?”. Then you want to know what the production rates for these machines are. If ther are I.E. time studies then you need to get them and compare them to the down time? What are the production rates being acquired as compared to the rates possible? How much of a factor does the down time play in this? For what reason(s)? No I.E. time studies? Them you will have to ask for them to be done… or you may have to do some time studies yourself. No records on any of the above? Then this is the first place to start. You will have to confer with manufacturing and maintenance to start keeping records on productivity and machine down time. Don’t be dishartened. If this is a trus six sigma project, then they don’t expect overnight answers. What is the scrap and rework rates? Why? How much does this play on the availability of machine time? Pick a group of common machines at atime. Don’t try to do the whole plant at one time. Common machines will give you the chance to do benchmarking…why is one machine doing so much better than the others? Match then all to the best one. Brainstorm the up time with the employees. What are all the possible hurdles to machine up time? What are the most likely? Brainstorm possible improvements. Find out were the most important bottlenecks are… or the most costly. Where can the fastest and most significant improvements be made? Start there. Confer with management to find out where the worst problems are. Confer with the employees as to why those problems exist and how they could be fixed.

    Im new to this but I understand that as I receive training I will do a project. I work for a Baldrige award winning manufacturing company. I’m a little nervous about this. Here is my first project:
    Manufacturing Leadtime Reduction: Improve the uptime availablility of critical machines (cnc lathes, mills machine centers, etc.) to ensure part delivery schedules are achieved. Any experience in this area? Any words of advice for a newbe???? Thanks Ken

    Thanks for the great feedback. I have some time (July) and yes we have history. Joe you idea of seeing both the best and worst performing is excellent. Mind if I use that??? Ken
