> It feels like software developers are scientists who study their customers' knowledge domains.
I agree so much with this. It's why I feel so stifled when an e.g. product manager tries to insulate and isolate me from the people who I'm trying to serve -- you (or a collective of yous) need to have access to both expertise in the domain you're serving, and expertise in the method of service, in order to develop an appropriate and satisfactory solution. Unnecessary games of telephone make it much harder for anyone to build an internal theory of the domain, which is absolutely essential for applying your engineering skills appropriately.
> so stifled when an e.g. product manager
Another facet of this is my annoyance at other developers when they persistently incurious about the domain. (Thankfully, this has not been too common.)
I don't just mean when there are tight deadlines, or there's a customer-from-heck who insists they always know best, but as their default mode of operation. I imagine it's like a gardener who cares only about the catalogue of tools, and just wants the bare-minimum knowledge to deal with any particular set of green thingies in the dirt.
This might be an indicator that PM isn't doing their job; PM should be able to answer you questions regarding what the business wants (= people who you're trying to serve). Developers, by the nature of interacting with domain, do become experts in the domain, but really it should be up to PM what the domain should be doing business-wise.
If that is what a PM needs then there aren't enough good PM to warrant a PM role for most products, so just make software engineers do that in most cases.
Edit: The main role of PM is to decide which features to build, not how those features should be built or how they should work. Someone has to decide what to build, that is the PM, but most PM are not very good at figuring out the best way for those features to work so its better if the programmers can talk to users directly there. Of course a PM could do that work if they are skilled at it, but most PM wont be.
> not [...] how they should work
So that we're on the same page, what I think should be PM responsibilities:
If I have a user story: "As a customer I want to purchase a product so that I can receive it at my address" - PM defines this user story as they have insight to decide if such feature is needed.
PM should then define acceptance criteria: "Given customer is logged in When they view Product page Then 'Add product to basket' button should appear", "Given 'Add product to basket' button When customers click on it Then Product information modal should appear" etc - PM should know what users actually want, ie whether modals should appears, or not; whether this feature should be available for logged users only, or not.
How this will work shouldn't matter to PM; these are AC they've defined.
Of course the process of defining AC should involve developers (and QA), because AC should be exhaustive to delivering given feature
This is why at my current place we are not supposed to do any dev without an SME on the call. We do the development and share the screen and get immediate feedback as we are working in real time! It's great.
