If you know of project managers in other industries, encourage them to ask questions here. In addition, here are some things we can do to attract non-programmer project manager types:
- Write the question to reflect a project management problem.
- In your question, avoid talking about programming, software engineering, Scrum, Agile, and topics that are specific to software.
- try to formulate your question so that it could apply to any project management field.
A great example of a question that fits these guidelines is What is the Relationship Between the Kano Model and Quality Function Deployment?
This question could relate to any field, such as manufacturing, and targets product quality. This could easily apply to construction, manufacturing, engineering, software development, and many more.
So far, the community seems to agree that project management is project management, and this includes the comments from active Stack Exchange Moderators.
In addition, the question of Merging IT Management with Project Management has also resulted in some agreement that ${INSERT_FIELD_HERE} Management will fit within the bounds of on-topic questions as well.
Also, see Are Questions about Product Management On or Off Topic.
This question has already been asked in multiple forms already, and it seems that the majority view project management as encompassing multiple fields.
