Customer Education Plan Generator — illustrative example

INPUT
Create a 15-minute lesson for customers who understand files but confuse matching keys. Example: two different customers share the name Sam; their customer IDs are C1 and C2.

RESULT
Minutes 0–3: explain that a key identifies a record; a name may not be unique.
Minutes 3–6: show Sam/C1 and Sam/C2 as distinct customers.
Minutes 6–11: learner matches an update for C2 and explains why name-only matching is ambiguous.
Minutes 11–15: review the choice and discuss what to do when an ID is missing.
Check: learner selects C2 and flags missing-key cases instead of guessing.

REVIEW
Customer education should build toward a useful task. Sequence knowledge and practice around actual user barriers instead of listing every feature.

This is a teaching example, not a live execution record.
