Start with the duty, then find the change
Copy one duty into a private worksheet and ask what was different after you did the work. Look for time saved, errors prevented, customers served, decisions enabled, risk reduced, revenue influenced, or a process adopted. “Responsible for reports” names an assignment; “rebuilt the weekly report so managers saw delayed orders before the planning meeting” names an action and change.
Record action, scope, result, and proof
Write four short fields before drafting: your first-person action, the scope you touched, the observable result, and where the fact came from. Scope can be a team, location, time period, volume, budget, or constraint. Proof might be a dashboard, review, project record, or colleague who saw the work. Do not place confidential evidence in a public resume.
Use a baseline before a percentage
A percentage needs a trustworthy baseline and end point. If those records do not exist, use a defensible before-and-after description or an absolute count you can explain. Keep estimates in your notes with the inputs and range. Never convert a rough memory into an exact metric because the bullet sounds stronger.
Draft the bullet and run the interview test
Use action plus scope plus result, then cut filler. Ask whether you could explain the baseline, your contribution, and the outcome in a follow-up interview. If not, soften the claim or collect better evidence. A resume is a compact index to a true story, not the whole story.
Study a fictional example
Synthetic example: “Reorganized a weekly inventory review across three fictional locations, helping supervisors flag backorders one day earlier.” The useful structure is action, scope, and observable change. It is not a template for borrowing numbers or claiming work you did not do.
