Any problem we have with questions specific to the tech industry(1) are also problems for questions specific to any other industry. There appears to be problem with tech industry questions because we have a lot of them and almost no questions specific to any other industry. The problems are much worse for the few non-tech industry questions posted because there are far fewer people who knowledgeable and enthusiastic to champion for those questions.
There are two general problems when a industry specific question is posed and people not familiar with the industry respond.
People not familiar with the industry makes assumptions which are incorrect.
People not familiar with the industry provide useful insights and are dismissed, (down-voted) because there point of view is at odds with conventional thinking in the industry.
We could suggest that all industry specific questions should be off topic. That is not realistic. All workplaces exist in an industry and every industry has its own practices and norms. Good answers must take into account the context of the question.
I suggest an number of approaches to deal with these issues.
The immediate thing is to try to find a good balance between thinking about the question in a general, non industry specific way, and also recognize that what is normal in one industry may be extraordinary in another. For example when a question about using git (a tool software developers use store and share versions of their computer code) is asked we should provide a answers which addresses both collaborating in general and also the specific practices withing the software development world. If non software developers offer their perspective we should not be careful not to immediately say they are wrong but instead try to understand their perspective.
This way of thinking should also be used when deciding to vote to close or reopen. A comment to explain why a close vote was cast will also help both the voter and everyone else decide when to think about the question generally and when to think about it in industry specific ways. If we don't see such a comment we should ask for one before we also vote.
The longer term thing we should do strive to make this site a welcoming place for people of every industry. This means being liberal in accepting industry specific questions. You may argue that these questions are off topic. The reality is that are slow to close very specific software development question. Being tolerate of questions about other disciplines will provide some balance. We also should also be cautious when close questions as duplicate of question which ask a similar question in different industries. It helps people feel welcome when they can see open questions about an industry they know. It is also the case that every often the answers are industry specific.
These things will not only help with how we handle non technology industry questions. When we have more people from other industries then everyone who frequents the site will become more aware to be sensitive to the industry specifics of all questions.
This advice is based on an assumption that it is very important that this is to be a place when people are welcome to come seek advice. This goal is in tension with the desire of some to build a corpus of great questions and answers. If curating an such a collection is important to you then you will probably disagree with some of the things I have written here. That’s okay because I believe there are no right answers, only helpful ones.
(1) The term “tech industry” is not well defined, I’m assuming we are all talking about the same industry, what ever it may be.
