Broad utility
ChatGPT is most useful when the workflow changes constantly and the team does not want a separate specialist tool for every task. It can move from planning to drafting to revision without much setup.
That flexibility makes it a practical default layer for knowledge work, especially when speed matters more than rigid workflow structure.
Where it fits best
It is strongest as a general-purpose assistant rather than a deeply specialized system. Teams usually get the most value when they use it to remove repetitive thinking and drafting work before human review.
In practice, it works well for content, operations, support, and lightweight research tasks that benefit from quick iteration.
