Here's a great ruleset for keeping things organised and efficient in your scrapping space - originally developed in the car industry in Japan I believe! You can see at once how it applies to scrap spaces though....
5S is a reference to five Japanese words that describe standardized cleanup:
Seiri (整理): tidiness, organization. Refers to the practice of sorting through all the tools, materials, etc., in the work area and keeping only essential items. Everything else is stored or discarded. This leads to fewer hazards and less clutter to interfere with productive work.
Seiton (整頓): orderliness. Focuses on the need for an orderly workplace. Tools, equipment, and materials must be systematically arranged for the easiest and most efficient access. There must be a place for everything, and everything must be in its place.
Seiso (清掃): cleanliness. Indicates the need to keep the workplace clean as well as neat. At the end of each work session, the work area is cleaned up and everything is restored to its place. (This sort of assumes you have a good spread of time to work in and are not doing 5 minutes here and there with other things going on too - multi-tasking is probably not efficient in this context!)
Seiketsu (清潔): standards. Allows for control and consistency. Basic housekeeping standards apply even in the scrap space. You know exactly what you need to do to tidy up, what your responsibilities are. House keeping duties are part of regular work routines.
Shitsuke (躾): sustaining discipline. Refers to maintaining standards and keeping your space in safe and efficient order day after day, year after year.
