Readme — Problem Structuring and Decision SupportFind a direct first result and an honest stop for the question at hand.
CitationCite the framework or one pattern with its author, release date and publication address.
PrefaceUnderstand how to combine qualified results while each supplying practice remains responsible for its conclusions and the authorized chooser makes the decision.
Development-direction advisingCompose development-direction advice from qualified holder-specific results.
Construct a Bounded Development OpportunityConstruct a useful conditional opportunity before a result is settled, without requiring an adviser.
Cross-pattern applicationsFollow the contested flood, development-direction and report handoff uses with their scope and source limits.
Framework boundary, sources and refreshFind the covered problem families, external returns, source arguments and affected-refresh conditions.
Source responsibility and referencesRead the advising sources, their qualification dates and limits without a separate working file.

Part I — Engagement, Participation, Formulation and Boundary

§ID & TitleStatusKeywords & Search QueriesDependencies
1PSD.1 - Bound the Decision-Support Engagement and Authority BoundaryCandidateengagement, authority, recipient. What advice is needed, for whom, and who makes the later choice?FPF A.15.9, A.10, C.11; PSD.2–PSD.4 when participation, formulations or scope remain live.
2PSD.2 - Recover Participants, Concerns, and Affected Systems for a Decision-Support InquiryCandidateparticipants, concerns, affected Systems. Whose consequential concern or absence could change the inquiry?Uses the bounded PSD.1 question; FPF A.1.CSD for consequence-bearer discovery.
3PSD.3 - Generate Plural Problem FormulationsCandidateplural formulations, framing, disagreement. Which different accounts imply different inquiries or interventions?PSD.1 and PSD.2 when their results are needed; FPF C.17 and C.18 only for their direct objects.
4PSD.4 - Set and Reopen the Problem BoundaryCandidateboundary, exclusions, scope, revision. What is the smallest usable cut, and what would reopen it?An adequate formulation and bounded engagement; PSD.1–PSD.3 for their live questions; FPF A.2.6 for exact scope membership when required.

Part II — Models, Methods and Facilitated Inquiry

§ID & TitleStatusKeywords & Search QueriesDependencies
5PSD.5 - Construct Complementary Situation and Option ModelsCandidatecomplementary models, questions, assumptions, losses. Which model supports which claim, and where does the join fail?Qualified inquiry inputs; FPF A.1.1, C.29 and A.10; PSD.6 or PSD.7 for their live questions.
6PSD.6 - Select Problem-Structuring Methods and Combine Them When NeededCandidateproblem-structuring Methods, fit, combination. Which reusable way supplies the missing contribution under these conditions?PSD.1; PSD.5 and PSD.7 when joined; FPF A.3.1, A.3.2 and B.1.5 for their exact claims.
7PSD.7 - Facilitate Decision-Support Inquiry and Preserve Material DissentCandidatefacilitation, attribution, meaning, dissent. What can participants recognize and what remains materially contested?PSD.2–PSD.4 when live; FPF A.2.9; specialist truth and authority remain direct returns.

Part III — Alternatives, Values, Uncertainty, Consequences and Robustness

§ID & TitleStatusKeywords & Search QueriesDependencies
8PSD.8 - Generate Decision AlternativesCandidatealternatives, mechanisms, staged directions. Which live candidate differs materially from the incumbent?Bounded engagement and formulation inputs; FPF C.17, C.18 and C.38 only when their results are needed.
9PSD.9 - Represent Values and Trade-OffsCandidatevalues, objectives, trade-offs, compensation. Which distinctions matter, and what must a score not compensate away?PSD.8 and PSD.11 inputs where needed; FPF A.19 and C.16 for applicable space or measurement claims.
10PSD.10 - Represent Decision-Relevant Uncertainty and Evidence LimitsCandidateuncertainty, evidence, scenarios, information. Which unknown can change eligibility, comparison or the current return?Uses actual candidate and consequence questions; FPF A.10 for reliance and C.11 for later probe choice.
11PSD.11 - Compare Consequences of Decision AlternativesCandidateconsequences, interactions, partial comparison. What follows under the stated configuration, and what comparison is warranted?Qualified PSD.8–PSD.10 inputs; FPF C.11.CRC and A.19.CPM for their direct comparison contributions.
12PSD.12 - Test Robustness and Sensitivity of Decision Alternatives and Their ComparisonCandidaterobustness, sensitivity, reversals, information value. Under which justified conditions does the result hold or reverse?Qualified comparison inputs; PSD.10 for unresolved evidence; FPF C.11 for an actual probe choice.

Part IV — Recommendation, Follow-up and the Development of Practice

§ID & TitleStatusKeywords & Search QueriesDependencies
13PSD.13 - Prepare and Return a Decision-Support RecommendationCandidaterecommendation, retained set, request, blocker, abstention. What can responsibly be returned now without taking the choice?PSD.1 and the qualified contributing PSD.8–PSD.12 results; FPF A.15.9, A.10 and C.11.
14PSD.14 - Arrange Decision Follow-up or Reassess Advice After a ChangeCandidatefollow-up, observation, interpretation, change. Which relied-on premise changed, and which advice must be reconsidered?PSD.13 when recommendation follow-up is live; FPF A.10 for one known reliance; A.10.1 when a changed source requires discovering and revalidating several uses; G.11 for currentness; direct subject or service guidance for its own question.
15PSD.15 - Decide Whether and How to Change Problem-Structuring and Decision-Support MethodsCandidateMethod repertoire, fit, evidence, source refresh. Which offering should be retained, changed, tested or retired?PSD.6 and actual follow-up evidence; direct Method-engineering and evidence results when required.
16PSD.16 - Reconcile Simultaneous Problem-Structuring and Decision-Support WorkCandidatesimultaneous inquiry, coupling, interference, facilitation. Which arrangement preserves a threatened result at acceptable burden?PSD.5–PSD.7 where their contributions interact; FPF C.32.MWA for needed several-structure synthesis.
17PSD.17 - Deliberately Continue and Change Problem-Structuring and Decision-Support CultureCandidatecultural continuation, interpretation, retention, mediation. What changes across practitioners beyond publication or local performance?PSD.15 and PSD.16 when current; FPF C.20 and C.36 for their direct cultural claims.
