One source of conflict is that many "business type" tasks/projects can be fairly easily time-scoped: "a report about opportunities for our product in Poland" can be a 5 minute comparison of populations, or a multi-year PhD dissertation.

Technical work often has a more rigid "minimum viable solution": a civil engineer can't just give up on a bridge halfway over a river, nor can he say "I just skipped the wind loading calculations and hope the school buses don't run on windy days." Some types of software (especially embedded e.g., aerospace and automotive) have similar concerns about safety and warranty.
