CHK.1:4 - Solution

CHK.1:4.1 - Recover the work and the consequential difference

Name the work result and the occasion at which an answer will matter. Identify the actual or prospective subjects: a physical set, a document edition, an import operation or the catalogue after it. Ask what was omitted, could plausibly be omitted, or remains difficult to notice. Include the encompassing use: why would this difference matter to the exercise, delivery or operation?

Use your own and others’ past omissions to propose questions, keeping the conditions that made each omission consequential. Look for patterns across incidents or records where a single account hides the connection. Ask what observation could challenge the favored explanation or desired answer. Prior mistakes suggest questions; they do not enumerate every possible failure. Place a revealing question early enough to avoid further work that its answer could make unnecessary.

Follow the actual production and use relations far enough to expose a consequential omission. Who or what produces this result, what enables that producer, and who uses the result? At a relevant link, distinguish the producer or user, descriptions of it, its way of working and its actual work. A missing intermediate service, tool or capable performer may deserve attention even when the final subject looks satisfactory. Stop following links when further detail cannot change the selected questions. If the prospective subject does not yet exist, ask about the available materials, descriptions or enabling results without treating a description as the existing subject.

Recover the descriptions used to judge the result and the assumptions connecting their described characteristics to that use. ME.3 helps construct criteria from the subject and situation. Use its account of criterion construction with the subject/description distinction in the Preface. When the criterion’s basis is unavailable, return that specific question to competent domain work.

CHK.1:4.2 - Propose questions and test their contribution

Write each candidate as a question with a recoverable subject and distinction. “Is the set ready?” may hide count, wording and assembly. Replace it with questions that can receive different answers where that difference changes the next move. Conversely, combine questions when splitting them creates effort without changing interpretation or action.

Choose how to obtain the questions from the uncertainty that remains. Direct practitioner selection can suffice for a familiar omission. Extract candidate questions from a usable description when the relevant properties are explicit, then ask whether those properties serve this use. Use generated proposals or comparisons between candidate results when they can expose a missing distinction. Compare the alternatives for the same needed coverage, including the effort of examining proposed criteria and removing duplicates. If the missing input is domain knowledge, another round of generation is useful only if it helps obtain that knowledge.

Comparing candidate results can reveal a missing question. Put a useful result beside a plausible but inadequate one and identify the consequential difference. Recover why it matters from the work and available domain knowledge; turn that difference into a candidate criterion. A generated contrast helps propose the question but does not establish that its preferred answer or coverage is sound.

For each candidate, establish:

• what it asks about, including an edition or time when relevant;
• which description, observation or judgement gives the answer meaning;
• why a different answer could change the work or a decision;
• who or what could supply sufficient grounds at the intended occasion.

These can be spoken answers in a small case. A maintained list benefits from nearby explanations where readers would otherwise guess. A criterion author can consult a specialist; the eventual user need not reproduce the author’s entire reasoning.

A question can support prevention, preparation for a possible failure or recovery after it. For the workshop, confirming usable backup materials can improve the response to a display failure without making that failure less likely. Ask what makes the action suitable for these actual participants and circumstances: printed copies may be ordinary access for one participant and backup for another. Keep the intended contribution explicit. Available backup materials do not establish a successful response, and preparation does not remove the possible value of improving the underlying technical Method.

A canvas can prompt inquiry as well as confirm conditions. “Who will use this result, and why?” may initiate a conversation that develops an account; “Have we identified the intended users?” asks about that account. Select the prompt that serves this occasion, and distinguish obtaining an answer from judging its adequacy. Filled sections can expose missing connections without establishing that the described proposal will work. For a seminar proposal, naming participants, activities and available support does not establish that those participants can attend or that the activities help them learn. Keep the substantive assumptions and grounds available for discussion; use the appropriate domain practice to test them.

Challenge the set with one plausible failure and one satisfactory case. Would they receive distinguishable answers? Does a missing item hide a consequential difference? Does an included item duplicate an already available adequate result? Use CHK.6 when the criterion or checking means itself remains uncertain.

CHK.1:4.3 - Select coverage and a useful stopping point

Retain questions whose expected contribution warrants their interruption and interpretation cost. Remove decorative, redundant or routinely unanswerable items, unless naming the unresolved contribution is itself useful. Keep the wider Method description or domain instruction reachable rather than copying it into a long list.

State the useful coverage in ordinary language: “These questions concern the physical set’s contents, wording and assembly.” State an uncovered question when it changes use: “They do not establish that the exercise teaches the intended distinction.” FPF B.1.5 helps distinguish the constituent result from the encompassing result; adding a whole-result question is worthwhile only when someone can supply its grounds.

Pass the selected questions and their meaning to CHK.2. Stop when further additions do not improve the intended use at worthwhile cost. Reopen selection after a missed consequential difference, a changed purpose or description, or repeated burden without benefit. Include a question about continued usefulness or feasibility when that premise can disappear during the work: an earlier decision to begin does not settle it for every later occasion. Obtain that judgement from the practice competent to supply it.

A discovered omission can suggest checking analogous subjects or implementations. Carry over the question and relevant source passage, then establish its applicability, observation route and answer for each subject. Keep assumptions about use, interfaces and dependencies visible. Agreement among several implementations can preserve the same mistaken interpretation; return to the substantive description and its grounds where that possibility matters. Neither an earlier failure nor an earlier pass transfers merely because the subjects look alike.
