Include it if the role adds meaningful evidence that is not already obvious elsewhere on your resume.

A short duration is not automatically a problem when the role was clearly contractual or project-based.

Label it accurately so the timeline makes sense, then focus on impact rather than explaining the short duration.

If the work was minor and crowds out stronger experience, it can be omitted. For more detail, see the consulting resume guide.

I kept one contract because it was my only strategy-related experience before applying.
