We often have the situation when a client is coming to a supplier 's factory for meeting, then the client is spending most of the time to explain how to do things, how to resolve a problem or how improve a situation. The important is to have discussion and have the supplier staffs involved in the work.
Use white board
The simplest way to have a good meeting is to use a whiteboard to write everything so all meeting attendees can read all progress of the meeting. Then also at the end of the meeting, take a photo of the whiteboard and send it as a meeting minute to all attendees and their supervisors.
Expose the problem
The most important is to expose the problem and rely the problem on facts like measurements, samples... Make sure your supplier really understands the problem, and everybody agrees on it.
Use a problem solving methodology
You may start the meeting in a formal meeting room or directly in production floor. You then can use all the methods like 5 why, the ishikawa diagram, the fmea... you do not need to mention what method you are using, but as the leader of the meeting orient the attendees to answer the questions. For example, you keep asking why 5 times in a gentle way so your attendees will not remark you are using the 5 why method.
Do not hesitate to go to production shop to have concrete analysis
For the analysis, it is good also to go on the shop floor to have direct analysis with the attendees. The first thing yo uneed to do is to have them explaining the problem or the situation.
Then, have all the attendees take a few step back to observe the situation to have a bigger view of the scene. Sometimes we are too close to situation to see anything, have them stand away and look for a few minute to analyse.
Having a external view is good to see things.
You are the leader of the meeting
As the leader of the meeting, you need to keep your attendees always excited, you will need to keep the fire on. You are the guy to push them at the limit, always asking questions to challenge them to have them think bigger.
Have everything written on the white, all ideas, no idea is stupid.
Then with all the ideas and analysis written, let re-discuss about the veracity of the ideas with every body and fix the actions to have proper counter measures, leadtime and action owners. For 1 action do pu only 1 owner of the action.
Appraise every attendees
Very important is to underline that evey attendee has an important contribution to the meeting, and let fix the next follow up meeting to review the progress of the actions.
