ACC-12 · Do no harm retirement
Kill a feature that tests poorly; write the memo explaining why shipping would be unethical.
The question
Kill a feature that tests poorly; write the memo explaining why shipping would be unethical.
Partners / materials
Evidence from prior briefs in this bank or a teacher-supplied failed eval. Retirement memo template: harm path, who is affected, what was refused, what replaces the feature (including “nothing”).
Expected failure modes
Softening the kill into “version 2 someday” with no criteria. Blaming users for failing the feature. Shipping anyway for showcase points.
Done looks like
Kill memo; evidence appendix; communication plan for partners who tested; showcase note that retirement is a successful outcome; non-claim list about what was never proven safe.
Five C's
CT: retirement as craft. CR: evidence-tied kill. CO: peer tries to argue for shipping — and fails or forces clearer criteria. CM: kill memo. CZ: people who would have been harmed by a ship.
Mentor role
Teacher or mentor signs that the kill is graded as success when justified. School-supervised.
Rubric calibration
R1: one feature. R2: evidence cited. R3: ship vs kill compared. R4: harm path explicit. R5: memo board/partner-ready. R6: refuses showcase pressure to ship.
Two ways this goes wrong
(a) “Needs more polish” with no kill. (b) Showcase ships the harmful demo anyway.
