Purpose: Write a timeclock pilot brief covering false rejections, correction workflows, alternatives, data handling and payroll reconciliation.

Instructions: Make a working copy. Fill the fields below with actual evidence and units. Record unavailable information as unknown, give it an owner, and resolve it before using the record for acceptance. Keep raw evidence by reference. Use the approved method, equipment limits and acceptance rules for your application. This blank record does not establish qualification.

1. Pilot purpose; sites/shifts; owner; technology and matching mode
   Response / evidence reference: ______________________________

2. Applicable jurisdiction; legal/privacy review reference and date
   Response / evidence reference: ______________________________

3. Enrollment process and approved alternative; no biometric samples in this record
   Response / evidence reference: ______________________________

4. Data-flow map; storage/access/providers/deletion evidence
   Response / evidence reference: ______________________________

5. First attempts / exceptions / retries / alternative successes; definitions
   Response / evidence reference: ______________________________

6. Controlled false-match evidence and limits; no inferred rate from usability counts
   Response / evidence reference: ______________________________

7. Offline/retry/duplicate/overnight/DST test cases and outcomes
   Response / evidence reference: ______________________________

8. Employee correction and review route; original/corrected event references
   Response / evidence reference: ______________________________

9. Payroll reconciliation sample; unresolved cases and owners
   Response / evidence reference: ______________________________

10. Approval and review triggers; vendor or policy changes
   Response / evidence reference: ______________________________

Teaching example (fictional; not acceptance criteria):
Fictional pilot denominators Of 1,000 legitimate first attempts, 40 require a retry or alternative, giving a 4% first-attempt exception rate. If 30 succeed on retry and 10 use the alternative, the first-attempt result remains 4%. These counts describe usability and recovery; they do not estimate the false-match rate, which needs separately designed evidence.
