Actionable methodology

Type: types/definition.md · Tags: method-guided-action

Actionable is the term this note defines. Methodology keeps its ordinary sense — guidance that maps represented conditions to a prescription, exclusion, ranking, or evaluation criterion, close to what information-systems scholar Shirley Gregor calls a Type V theory. A theory that only describes or explains, supplying nothing that discriminates among interventions, is not a methodology in that ordinary sense, however true it is; Commonplace does not additionally stipulate this as a technical condition, since the word already carries it.

A methodology is actionable for a particular operator, on a given task, in a stated setting, when that operator can use its mapping to choose among available interventions in a target system. This is the relation Commonplace adds: a methodology nobody can apply here and now, to this task, is still a methodology; it is simply not actionable in that setting. Actionability is a relation a methodology stands in, not a kind of artifact — there is no separate thing called an "actionable theory."

The relation requires five elements

  • A methodology that applies to the target and supplies an intervention-relevant mapping.
  • A task that fixes the objective, the cases it admits, and the success criterion the selection is judged against.
  • An operator, including any interpreter it relies on, that can follow the mapping with enough fidelity for the mapping's distinctions to change its selection.
  • A set of available operations for which the operator has the necessary access, resources, and authority in the stated setting.
  • A target system that those operations can reach and affect.

The operator may be a person, an organization, a trained model, deterministic software, or a combination of them. Within such an arrangement, the interpreter is the part that realizes the mapping from conditions to a selection among operations.

The task supplies the application area; the methodology carries none of its own. It is an input to the relation, not something the relation establishes, so actionability on one task says nothing about a wider one. Extending the application area is either a new claim about the methodology or a revised task, and either needs its own check.

A task is also written for a particular operator and names only the functions that operator consumes. When the operator changes, the functions the previous operator supplied to its surroundings fall outside the task unless it is restated to include them. Norman's autopilot case is the origin of this point: handing control from a first officer to an autopilot kept the delegated function and silently dropped the anomaly reporting the human delegate had supplied (Norman 1989).

Scope

The ordinary sense of methodology used here starts from information-systems scholar Shirley Gregor's theory for design and action. Type V theory “says how to do something” by prescribing methods, techniques, or principles for constructing an artifact (Gregor 2006, printed pp. 619–620; PDF pp. 10–11); membership does not require a currently capable or authorized operator.

Actionable adds the operational relation Gregor's taxonomy does not carry. A design-and-action theory sitting unread in a paper remains prescriptive — it is still a methodology — but it is not actionable in a particular setting unless an operator can use its mapping through available operations on the target. Theory type and situated actionability therefore answer different questions; actionability is not a proposed sixth type in Gregor's taxonomy.

Prescriptiveness and actionability come apart in both directions. A software-architecture methodology can be actionable for a developer before the developer acts on it: it maps architectural conditions to component and interface choices, and the developer has the access and authority to make those changes. If the developer loses repository access, it remains a methodology but is no longer actionable for that developer in that setting — it is still prescriptive, but the operational relation fails. Conversely, repository access alone actions nothing if the theory supplies no intervention-relevant mapping for the software system — the relation's other elements hold, but there is nothing to act on.

Evaluation contributes to actionability only when its result can affect the selection, retention, or modification of an intervention. Retrospective analysis with no path into action may be informative, but it is not actionable in this sense.

Exclusions

Actionable is not a compliment: the mapping, task, operator, available operations, target, and setting must be identifiable, or the word is doing no work. Methodology is not a synonym for practical-sounding advice — a theory that only describes or explains is not a methodology, however true it is.

Actionability implies neither that the methodology is correct nor that an intervention will succeed. Gregor's “if acted upon” causal expectation remains conditional on the actor and setting (Gregor 2006, printed p. 619; PDF p. 10).

Misuse Cases

  • Calling a design paper actionable for an organization that lacks the access, resources, or authority to apply it.
  • Calling an instruction actionable without identifying the system and operations to which it applies.
  • Calling a methodology actionable without naming the task whose success criterion the selection is judged against.
  • Calling a classification actionable because a resourceful operator could invent a use for it, even though the classification supplies no intervention-relevant mapping.
  • Treating success on one task as evidence that the methodology is actionable on a wider one.
  • Carrying a task written for one operator over to another without restating the functions the first operator supplied beyond it.
  • Treating actionability as an intrinsic property of natural language, independent of an operator, task, and setting.
  • Using actionable theory as a noun, as if actionability sorted artifacts into kinds rather than relating a methodology to an operator.
