Our production team have a Tolbox meeting daily, we find this is the best avenue to discuss not only the customers, but also our own issues.
We also pass on good news and congratulations at this meeting where warranted. It seems to work well.
This week we extended an invitation to our customer (they were on site doing other things) to attend the toolbox. Good News and Not So Good News items were discussed. After the meeting, the team had a better idea of why we do what we do and what the customers expectations are.
