I can see how it would be easy to debate, as it's hard to quantify even after applying it. This is apparent (to me) in how easy it is to spin a bad outcome into looking like a shining success. There's always that shotgun card in the back pocket if things go south; you know, that card that politicians always play, "Well, just imagine how bad things would be right now if we hadn't applied these principles." Almost a religious debate.Preventative maintenance is one of those things that academics like to argue about. Just like competence development and seatbelts, it's hard to argue the specifics of the cost if one does not apply it.
This is not unique to 5S/Lean, and IMO it's the hallmark of an ineffective communicator somewhere along the line, probably at the helm of the meeting. I've come out of meetings in the Navy and in various places I've worked and been amazed at how different people walked away with different understandings of the materials presented. My last employer had a pretty effective method for dealing with this; they would have online quizzes once or twice per week. Management reviewed the quizzes, which questions people were getting wrong, and got another chance at the next meeting to drive the point home.you have one guy teaching it to 30 people. 20 out of the 30 all may have a different interpretation as to what they were told. [...] to make it work correctly, EVERYONE needs to be on board with it and all need to understand it the same way.
Yeah that sounds about right. I worked in maintenance and had a small cart that I pushed around with my tool bags/tool boxes of most frequently used tools on it. It was nimble, and could fit easily through doors and between machines to get back into the nooks and crannies where I needed to work. I also had a 800lb rolling toolbox that had all my heavy mechanical tools in it, which I only used for major breakdown/rebuilds, as it was a royal pain to drag/push it all around the plant. When 5S started making its rounds through the plant, it eventually made it to Maintenance. I had seen what silly things they enforced on Production, and could only imagine what would be in store for Maintenance. They made me throw away my nifty little cart and told me that I needed to consolidate all my tools into the big rolling chest and line each drawer with 1" thick foam. I was to make a cutout in the foam for each tool. That sounds like it would look real nice, but the problem is that when I consolidated all my tools, they barely all fit into the rolling chest stacked on top of eachother. I asked whether I should forego the foam or order 3 more rolling chests to fit all my tools in this space-inefficient organization scheme. I was told to get rid of whatever tools I didn't use often. HA! Ok. I have specialty tools which are only used once in a blue moon, but when they are needed, they are needed, and they are expensive. So I got rid of a few thousand dollars in tools. After that, every time I turned around I was in a scenario where I needed a certain tool but didn't have it, and had to improvise. I used pipe wrenches on things that required a spanner. I invented all sorts of ways to get snap rings off, in the absence of a proper set of snap ring pliers. I had to get rid of my oscilloscope and make due with a multimeter, so true troubleshooting gave way to blanket replacing of probably-good expensive electronic parts. I also stopped bringing my tools to the scene of the failure each time, because I didn't want to throw out my back dragging the now >1000lb toolbox everywhere, so I would show up with whatever tools I had on my person. Once I had surveyed the problem, unless I perceived that I would need more than a handful of tools, I would leave my "portable" toolbox sitting right there on it's painted yellow square. Production had to wait sometimes for me to make an extra trip back across the plant to it if I needed something else. I can see how this type of organization scheme could have benefited someone in Production, who uses the same tools day in and day out, who's work station is really a station, and who doesnt really have to come up with solution to problems, but for Maintenance, I felt like we should have been an exception. I sure everybody in Production felt that they should have been an exception as well, so it had to be blanket enforcement I guess. Oh well, I don't work there anymore.what I found really ridiculous about it was the we had to have every single thing taped off and labeled. Square tape marks all over the floor for your chair, trashcan, around your desk, square tape marks on your desk, for your stapler, for a manual, around the telephone, and everything had to have a label showing where it went. Why in the hell do you have to have a label on a broom that says "BROOM". Everyone in that shop is smart enough to know what a broom is, so why label it? Behind our lathe and mills, on the power boxes, they had to have orange squares on the floor underneath the powerbox designating that there was a power box above the square. This is how our shop implemented 5S :nuts:
I just saw a crazy rule they have about "lock-out" I was working on a Do-All surface grinder last week and I asked the maintenance man helper to lock out the power after the foreman told me pulling the breaker was not good enough. Well yesterday I went looking for the key for the lock. I assumed there would be a cabinet for keys located where all the lock-out forms, tags, locks were in the maintenance crib. A central location for all the keys...I looked and nothing....I saw the foreman and said I wonder where the key is for the machine I'm finishing up is?
He looked at me and said "The man who puts the lock on has to keep the key on his person 24/7 until he unlocks the breaker." I was shocked and said "are you serious?" He said, "it was the rules"....so I went looking for the maintenance man who had helped me. He is around 60 and told me the stupid child like rules he has to follow makes him sick. Some liberal BS that some educated idiot dreamed up.
The MM said he was violating the rules as he had the key in his tool box and didn't take it home or wear it around his neck on a chain. He went and got it and said he was again violating the rules by letting me have it, but said "F the rules".....The stupidest thing I ever saw... I did see one other thing that was almost as bad....where you clean your safety glasses in the break room......The procedure on the wall said: Remove your safety glasses, put on safety glasses provided and squirt your glasses with cleaner, wipe, remove safety glasses provided and place in rack, put your clean safety glasses back on..... Talk about a Nanny State...My god...

LO/TO is brilliant, so I learned. I had a close brush with death after failing to adhere to the LO/TO policy. We had a machine that had a communications bus passing through a series of slip rings and were experiencing problems with it. At least once per shift, the machine would start having communications problems and we would have to shut it off, climb inside the machine in several different areas to access the sliprings and clean them. We also got in the habit of turning power off to the machine between shifts, as the problem seemed to be worse, the longer we left it sitting on but not running. Next to the low voltage slip rings were 680VDC sliprings. Due to the frequency of this operation, I became lax in my implementation of the LO/TO procedure. The operator would come get me and say "need to clean the sliprings again" and I would say "ok, I'm turning off the power, and I'll let you know when I'm done." One day on a weekend, I came in at an oddball time, as maintenance schedule did not jive with production schedule. The operator came and got me to clean the sliprings and I informed him that I was turning the machine off and getting inside. He said "ok" but failed to inform me that he was at the end of his shift, and failed to inform the the second shift operator that I was inside the machine. Second shift operator comes along not 30 seconds after I turned off the power and turns it back on. Meanwhile, I climb inside the machine and take the guard off the slipring assembly and start to clean the communications bus rings. I was in a wierd position and uncomfortable so I decided to brace myself against the slipring assembly. My left arm made ever so slight contact between the (+) and (-) of the 680VDC bus. A loud alien noise involuntarily came out of my mouth and I threw myself head-first into a big chunk of steel. I had some slight burns on my arm and goose egg on my head, but really I am one lucky SOB. He could have started that machine and turned me into hamburger. So I am a believer in the LO/TO procedure now, but not necessarily in the way they were describing - as in the guy taking the key home with him. IMO the way it should work is everybody has their own lock. Always use the multi-hole lockout clamp device that accepts multiple locks. Anybody who is working on the machine puts their lock on the clamp device while they are working, and takes it off when they are done. If there is work that spans multiple shifts, the oncoming guy puts his lock on before the offgoing guy takes his off. There should be a master lock that gets put on when the paperwork starts and gets taken off when it's cleared, and this key should be accessible by any and all persons who may present, qualified, and sufficiently informed of the job status to declare the job finished. This way the machine doesn't set idle when work is complete and nobody gets hurt.Much though I dislike petty 'rules for the sake of rules', the lockout procedure is actually a good one.There have been many instances of power being restored to machines that someone was working on, and many instances of people being maimed or killed because of it.Having one person responsible for the lockout tag, and only one, ensures that power cannot inadvertantly be restored without authorization.The maintainence personel can safely work on the machine in the knowledge that the tag won't be released until they personally request the keyholder to do so.M
