You need to identify assumptions as part of the assessment of capability gaps. Which of the following is an example of an assumption?

The project manager's belief that team members can program in COBOL is an assumption because it is accepted as true without confirmed evidence or formal verification. If this assumption is incorrect, it represents a capability gap that could impact the project's delivery. Documenting and validating such assumptions is a required step in capability gap assessment under business analysis frameworks.

Requiring vendors to hold security clearance is a constraint - a mandatory condition imposed on the project that restricts how it must be executed.

Software compatibility with the current operating system is a requirement or technical constraint, not an unverified belief held by a team member.

The directive that project risk must be quantified is a project management requirement or governance constraint, not an unverified assumption.
