This comes from my days in custom fabrication. Still applies.
You had the office and shop. Job tickets were generated in the office. Pull sheets were the responsibility of the office. Job blueprints were generated there also.
Once the office did their part the full packets were put in slots on a crew board in their respective areas.
By the time the "packets" hit the floor necessary parts had been ordered or fabricated and were ready to be pulled from inventory. Other bits and pieces were loaded onto custom carts.
Pulling parts fell to the team lead. Something missing or screwed up the supervisor was notified.
Within these packets were sign off areas. If you pulled parts from stock or a WIP(work in progress) that was signed for also.
WIP Stores could be a staging point for completed graphic/wrap packages. WIP stores responsibility was to ensure that everything they were supposed to have was actually accounted for. If not the job couldn't be released.
As you completed work according to the SOE's(sequence of events) you had to initial and date.
Traceability, accountability, and owning what you did were the rule.
You may want to look at an expediter too. They were the shop guys that went to all the jobs putting out fires and bird dogging whatever. One expediter was worth twice what they paid them. It completely stops people from wandering around looking for bits and pieces instead of doing their job.
There were also employees involved in "delivering the mail". They would deliver and stage whatever needed delivering and staging to its respective area. This usually happened on second or third shifts.
Another thing you might want to look at is Six Sigma principles.(there is good and bad with Six Sigma and I don't wish to start a debate)
Following some of their guidelines will allow you to set up work cells for very specific functions. It will virtually eliminate the time wasted looking for tools. You will be able to streamline certain processes based on specialization.
This book is an interesting read: “
The Goal: A process of ongoing improvement,” by Eliyahu Goldratt
If you read this you will be looking for "Herbie's" in your shop.
