The job of engineers is not to deploy some technology but to build robust, reliable and sustainable (in all meanings of that word) solutions for real world problems based on requirements directly derived from people's needs.

@tante The job of the engineer is to meet the specification. Period.
@Wyatt_H_Knott @tante Perhaps for a junior engineering role, but I'd expect anyone in a more senior role to understand the context of the specification and the constraints that led to it, and where appropriate to discuss alternatives with the relevant stakeholders. With increasing seniority there should be a widening scope of awareness.

@tante i love this thread.
only a bunch Of engineers would debate this great post.

@GerardThornley @tante Sure, yes. And for sure I was able to have discussions with contract supervisors where we could suggest modifications to the specification requirements in certain limited scope cases. But it was always a fight, and often the outcome rested on a political consideration rather than a purely technical one. The truth is there are MANY ways to do most things and what we were doing was picking one that jibed with the rest of our manufacturing ethic.

@tante Sun Tsu's "The Art of War", specifically the section on Tactics, is surprisingly relevant in Software Engineering. You have a powerful army. Don't ask it to do something it can't do

@Wyatt_H_Knott @tante Oh, for sure. I think we engineers often start out hoping that engineering decisions will flow from what makes the most sense, technically, only to discover that in large organisations (where most engineering happens) it's politics (a skill not typically taught to engineers) that rules.
I've certainly seen some dumb things done to satisfy political constraints, and with long-lasting consequences. And in a nod to the original post, I should note that some of those were made by engineers focusing on their own technical area of a product to the detriment of the product as a whole. -
@Colman Probably not. The specs came from the contract. The contract came from the Navy. The Navy thinks they know what they want, so they are very detailed about their specs. It's why we don't deviate very much. Specifications are commercial contracts. They say "do they job according to such and such standard to produce X result." Maybe there was a smart engineer involved in producing the standard, or maybe a bunch of managers sat around with their heads up their asses justifying their jobs.
@Wyatt_H_Knott @Colman And then there are Navy contracts with all the the mechanical interface specs as "figure it out with the ship SPO". Not exactly helpful when you're designing something that goes on every major ship class, and when the SPOs won't give you drawings or access. Flickr to the rescue sometimes, especially for the high res pics.

@ingram @Colman That was usually the point where I would walk down the hall, or to another department, and start digging through someone's private filing cabinet of legacy classified drawings.
Which is why we worked so hard to get production rates up - to be able to keep legacy engineers and historical build data in house and actually usable. Because all those files were worthless without the engineer who collected them and could give you the right set of notes without looking anything up.

@alatiera @tante Then I think the phrase "don't have a single clue" might be putting it a little bit strongly!
For the software managing, for example, the timing of fuel injectors and spark plugs in all modern internal combustion engines, the engineers will have a very high (and justifiably high) level of confidence in how it will behave.
That's built on a great deal of work to measure things like the behaviour of raw materials (electronic components) including failure rates and conditions, model the behaviour of the system in a range of scenarios, and test the product at multiple stages during both design and manufacture.
All the same processes that give confidence in the construction of a bridge.In neither case will these efforts always manage to catch every single unintended outcome. A _fairly_ recent example would be the London millennium bridge, a footbridge over the Thames, which happened to have a resonant frequency at around people's walking pace, and had to have dampers added after construction to prevent an unpleasant rocking motion.

@Wyatt_H_Knott Yikes, when did you take Engineering Ethics? Never?
