要点

impactは1 minimal〜4 severeをaffected people、workflow、data、scope、reversibility、business consequenceで評価。urgencyは1 planned〜4 act nowをworsening time、deadline、workaround endurance、containment、recovery windowで評価。4×4でinitial P1–P4を作りsafety、security、privacy、fraud、data loss、legal/regulatory、accessibility、contract overrideを適用。owner/reassessment timeを置きevidence変更時に再計算します。

labelは例でuniversal SLA promiseではありません。組織がrisk、service、contract、capacityに合うobjective、incident criteria、authority、escalationを定義します。

priority、severity、impact、urgencyは別物

severityはcondition/consequence、impactはscope/harm、urgencyはresponseのtime-to-change、priorityはcapacity/dependency/override後のqueue decision、SLAは存在する場合の別service commitment。

impactはuser countだけでない

workflow criticality、data integrity/confidentiality/availability、safety、accessibility、financial/contract consequence、市場/account、reversibility、workaround cost、spreadを評価。一人でもhigh urgency、多数でもcurrent defectなしならlow urgencyがあり得ます。

urgencyはtoneでなくtime-to-harm

verified deadline、deterioration、containment window、workaround endurance、recovery lead time、delayがevidence/restorationへ与える影響を使用。ALL CAPS、executive、tier、ticket age、repeat contactは調査signalで自動urgencyではない。

override/incident declarationはmatrixより上

active safety/security/fraud、privacy breach疑い、destructive data loss、regulatory reporting、accessibility exclusion、credible threat、contract triggerはcellに関係なくspecialist pathへ。ownerがscopeを検証しelevate/contain/reclassify。

実例:最も強い口調でも自動P1でない

executiveがexport失敗を“URGENT—broken”と書きautomationはtitle/capsでP1。evidenceは一user、malformed filter、source data intact、安全export workaround、meetingは2日後:I1/U2→P4。reviewでworkaroundがscreen reader非対応、statutory submissionが本日expiryと判明しI2/U4→P2+accessibility override。

なぜ時点ごとに両decisionが正しいか

priorityはcurrent evidenceに従いprestige/permanent labelではない。original fact、missing accessibility/deadline question、changed evidence、old/new score、reviewer、owner、strategy、next reassessmentを保存。new material factで変更はmodel failureでなく再評価しないことがfailure。

Decision title/emotional toneをscoring featureから除外しaccessible workaround/external deadline question、人override/reassessmentを追加。

matrixの運用

minimum factでtriage

exact task、scope、time、evidence、deadline、workaround、risk flag、contact route、uncertaintyを記録。

matrix/overrideを分離

raw impact/urgency rationaleを保存後にspecialist/contract elevation。

response roleを割当て

ticket owner、resolver、必要時IC/communications lead、customer owner、decision authorityを指定。

verified stateをcommunicate

known impact、action、workaround limit、next update、correctionを共有し未検証cause/resolution timeは不可。

evidenceでreassess/close

scope/urgency変化でpriority変更しrecovery、residual risk、user outcome、linked problem、follow-upを確認。

minimum priority decision record

ticket/correlation ID、source/exact report、requester/contact、affected people/account/region、product/version/environment、task、start/last-good、evidence/telemetry、current/potential impact、deadline/time-to-harm、workaround/endurance、reversibility、risk flags、impact/urgency/rationale、override、priority、confidence、missing fact、owner/role、objective、reassessment、status、recovery、correction、closureを保存。

fairness、drift、outcomeをaudit

new evidence repriority、false P1/P4、missed override、unowned time、duplicate incident、inaccessible workaround、objective breach、update correction、reopen、residual harm、product/market/channel差を測定しprotected traitでdeprioritizeしない。

  • authorized verification前にroot cause、resolution time、compensation、breach、safety、legal conclusionを約束しない。

よくある質問

priorityとseverityは同じ?

いいえ。severityはcondition/consequence、priorityはimpact、urgency、capacity、override後のresponse decision。

一userは常にlow?

いいえ。time-critical、inaccessible alternative、safety、data、fraud、legal、contractでurgency/override。

VIPはhigh priority?

contract commitmentはobjectiveへ影響し得るがstatusだけでimpact/urgency evidenceやfairness/safetyを置換しない。

いつpriority変更?

scope、harm、deadline、workaround、containment、recovery、override evidence変更時。customer escalationだけではない。

P1は即時resolution?

いいえ。local ruleのresponse priority。verified action/update cadenceを伝え実service commitmentはcontract次第。

OpenMax の役割?
