How does your company organize tools / 5s in your r&d shop space?

I'm a tradesperson turned mechanical technologist. I work in design for a late stage startup. Our shop floor and tool situation is... Chaotic. I joined up the the terminal phase of a failed 5s environment, where it’s too late to save it without chucking it all and starting over. Plundered drill indexes, wrenches disappear, etc. I'm from a shop floor background, I've been a part of and know what a successful 5S environment for production looks like. I know what works when it’s all trades and production cells, but an R&D environment is different. More fast paced, more variety, it’s much much harder to begin the 1st stage of a 5S, the “sort”. We need a wide variety of hand, power, fabrication and measuring tools available in a fairly unpredictable pattern. Our main issue is tools disappearing. My usual approach to that is to “flood” and “identify”. People steal tools when they can’t find what they need, and don’t return them when they both forget to return, and forget where the tool came from. I want to have enough tools to have them readily available, and have the tools so obviously identifiable that you can see from 10 feet away if that tool needs to go back to its home. I don’t like tools in drawers. I want to see everything fast. If I can’t find my tool, as someone new, in less than 15-30 seconds, it’s a failed system. The problem here is 5S boards aren’t usually very dense, without putting incredible amounts of work into a careful layout that inevitably becomes out of date when your tool requirements change. Maybe a “see through” drawer? Does that exist? So how do I solve the 2 main issues: 1- Storage in a visual shadowboarded way for large amounts of unique tooling, -Multiple vertical leaf through panels? Like they used for flipping through posters - I am not a fan of the traditional pegboard. The hooks fall out and the board falls apart too fast. -I actually like screws or bolts in thick plywood, but that has lots of other issues. Main advantage is easy to reconfigure. -Shadowboard tracing I have had luck with simple paint marker outlines. The main problem with shadowboarding is it is so labour intensive to setup. 2- Tool identification. -words are not obvious enough -tape doesn’t last -spray paint is ugly (but an option) -I’ve seen nail polish enamel used with success I’m just hoping for some examples and advice here… A pretty shadow board example where they have pliers, cutters, a wrench set, and a couple sockets isn’t going to cut it.
