These process-induced disasters come about because process is the ultimate slippery slope. It starts out as an innocent routine. Something needs to be checked on a regular basis, so you make it a thing you do each morning, or at month end. Then you start to see similar mistakes being made more often than you'd like, so you make up a rule that says every time you do A, you need to check B. Perfectly sensible. Then you start to notice that miscommunication is a problem, so you create a form to minimise the possible ways people can express things to help overcome language barriers and local phrasing. It just makes things easier. Then you notice that the people who used to do all this stuff don't really need to think much, because all they have to do is follow the schedule, follow the rules, fill out the forms, enter the form data, so it would be much cheaper to employ less skilled people.
At about this time the CEO is looking at the bottom line and he's* pretty pleased with it all. The company is declared "efficient", possibly even "quality assured". There are bonuses (not for the unskilled staff, of course), there are options, Capitalism is pleased.
Then one day a customer calls, and they want something that requires the schedule to be modified slightly, or the rules to be broken, or gods help us, an answer that isn't available on the form. Those low paid, unskilled staff are not too interested in working out how to accommodate this customer, so they just say "no". Customer goes away and grumbles.
As this happens more often, CEO decides they need more sales staff to improve revenues. CEO spends some real money on sales staff, Capitalism approves of paying sales staff Good Money. A sales person goes out and talks to the customer and finds out what they need. It seems pretty sensible, there's no reason why the company can't do that. They sell the product to the customer. The customer then gets sent back to the same low paid staff who were uninterested in the Problems of Process the customer presented the first time, and is told "no" again. This time, the customer doesn't go away and grumble, this time the customer gets very upset. They've paid for this product, they've been told they can have it. They are told by low paid staff that what they want is Impossible. The customer knows perfectly well it isn't really impossible, but equally, the low paid staff know that from their perspective, it may as well be.
And now we know that process is really in place. And you can pretty much guarantee that no mistakes will be made by human error, because human error requires human input.
So next time you hear someone say "It wasn't human error, we need to look at the processes we have in place" as though this is a Good Thing, throw rotten tomatoes at them, or at least say loudly and clearly that you are perfectly willing to accept human error, but that if processes are making mistakes, the Powers That Be have failed utterly in their management roles.
*God yes, he's a "he". There may be CEOs for whom the pronoun "she" is appropriate who make these kinds of decisions, but they've never crossed my path.
