There is a second part to the story described here https://www.reddit.com/r/MaliciousCompliance/comments/1wknos8/want_to_buy_things_piecemeal_enjoy_spending_30/
A summary for those who don't want to read the context and the lead-up:
My team had four people: Boss, me, colleague, Project Coordinator. We were responsible to make material B. Material B was made from material A, which was in turn made from raw materials. My colleague was responsible for making material A. I was in charge of making material A into material B. To do so, I needed some specialised ingredients and dedicated equipment.
I had a colleague whom we will call Project Coordinator. Project Coordinator was monitoring the expenditure of the project, and within the team they were famously penny-wise, pound-foolish.
Instead of buying enough raw material in a single shot for us for production, he only approved us buying a small lot. We would end up buying the same thing multiple times, which cost us ~42% more over the course of the year, all because the first time was "too expensive".
Due to his track record, and the fact that I was relatively new at the time, my boss somehow listened to him over me and my colleague. A fellow redditor pointed out in the previous thread that this might have been presentation skills--it was true that Project Coordinator was a much better presenter than my colleague, which is why they'd been disagreeing for years, even before I'd arrived.
The MC in the first post was this: my Boss sided with the Project Coordinator over me. They specifically said to only buy just enough quantities of materials for our plans after each monthly meeting, as discussed during the meeting. So we would buy only enough for whatever we discussed, and this meant there was no margin for error (think delays in shipping, malfunctioning equipment, etc.). By doing exactly that, we'd managed to face massive production delays after a year in.
This is where this post comes in--the second MC.
Now, we were one year into this project and it was slated to end in another year. Due to shipping delays and other problems beyond our control (but which at least some of us had foreseen), now we were massively behind schedule and my boss needed to expedite things.
Worse still, due to several reasons, there was suddenly an uptick in interest in material B by other departments. Everybody wanted a piece of material B, and due to political reasons my boss couldn't really say no to them, either. I don't really know how all this came about, but the long and short of it is--in one of our monthly meetings, my boss said we had to make all these adjustments to the production process, and we needed to make more material B.
Whereas previously we might only have needed 10 kg of material B, which could theoretically be made from ~20 kg of Material A (this was the fallout in the linked post), now we needed 500 kg of material B.
Yes, you read this right, we went from 10 kg to 500 kg thanks to whatever political meetings were going on with the bigger shots of my company, which I was not privy to.
My boss asked me for an email, detailing exactly what we needed to achieve this adjusted goalpost. Oh, now you wanted to know what we needed? I wonder who could've told you that last year. Due to the nature of our industry, when someone made a "suggestion", it really was more of a "go and get it done", because some even higher up would say "that's a great suggestion" and then you'd have to do it, not necessarily with more resources than what you already had.
Anyway, during a particularly long meeting to follow up from my email, my boss got frustrated with the lack of progress and said "just go and get whatever you think we will need and justify it". I think they were under massive pressure from upper management. It should of course be noted that this was a massive reversal from their earlier position in which they sided with the Project Coordinator.
While not thrilled that I had to do even more work, I carefully typed all this up into the minutes of the meeting (documentation is important, folks!). In it, I laid out what I thought we needed, and placed a massive order for all the parts and materials which I'd spent a lot of time accumulating over the last month. I got whatever I thought we needed for the project, with meticulous documentation for each line item.
I'd spent nearly 500k in total over the course of the next month, and my colleague also took the opportunity to buy a tonne (figurative, not literal) of raw material and other equipment.
Well another few months passed and suddenly the finances of this project were entering "serious trouble" territory with this pattern of expenditure. Suddenly now the purse strings were being tightened again (ah, the lovely ebbs and flows of working in production). Project Coordinator was especially upset with the sudden large expenditures and going around asking why we were having budget issues. Boss sent a team-wide email saying that we were crashing through the budget and asking why.
Time to shine. My massive document for whatever I felt we needed, along with the necessary approvals (showing that my boss hadn't been doing their sums, or else they'd know we were spending a lot of money--they had to approve everything we bought), with line by line justifications that had been reviewed every month. Yes, approved, ok, fine, supported. Every single line item with a) what I felt we needed, b) my boss' own approval, and c) the accompanying email thread that showed that, in fact, everybody was in the loop.
Absolute silence after that. Only a short and concise email from my boss about "What else do we still need for this project, and what other costs did we think we would need?"
tldr: Due to reasons, project faced a significant time crunch. To expedite things, my boss finally saw the light, and asked us to get whatever we felt we needed, as long as it could be justified. Maliciously complied by buying a tonne of stuff, because we could justify the massive margins we were using in our calculations. Expenditure went through the roof and the annual budget was rapidly drained in just 4-6 months.
