Excel template

Try a few more to see what layout you like or do not like. You will have to customise it a little to suit the way you think and how your parts are stored.

Apply the 5S principle.

Sort out your stuff. Group like stuff with like stuff, maybe even using the parts microfiche as a way of grouping your parts together. Label your boxes so you know what is where. Make sure the physical storage stays aligned with your spreadsheet.

If you need help modifying one of the spreadsheet templates, happy to help.

Good luck and keep us posted!
