Design a controlled improvement test

Write the Plan section before processing the cards: the hypothesis is that requiring a known, approved location at intake prevents missing-location confirmations. Keep all other process steps unchanged. Name the fictional process coordinator as owner and the scope as P01–P10. Predict at least 9/10 first-pass-correct confirmations, median elapsed time at most 20 minutes and total review effort at most 35 minutes. Preserve the previous optional-location form as version 1 and label the test form version 2.

Create a ten-row Do log with columns ID, submitted location, approved location, intake action, first-final-check result, correction, elapsed minutes and review minutes. Apply only this revised intake rule: accept a populated location that agrees with the approved record; if blank but the approved location is known, copy it from that record and note the correction before entry; if genuinely unknown, stop the pilot, use the clarification path and restore version 1 for further intake until a safe revision is tested. Never invent a room. These are supplied paper cards, not live submissions. Read each card as an approved workshop/time/location record plus its submitted intake location and draft confirmation at the first final check. Every draft contains the workshop and location shown in the approved record exactly once; its time is stated explicitly. Compare all three fields, mark initial pass or correction needed, and retain the supplied observations. Elapsed time runs from request arrival through correct release, including correction; review effort is the total checking work per request. Do not replace the given observations with guessed timings.

Process each supplied card below using the intake rule and record its first-check result in your Do log. Keep the observations attached to their request ID.

Card P01: approved record = Seed Workshop, 09:00, room Cedar;
submitted intake location = Cedar;
first-check draft = Seed Workshop, 09:00, room Cedar, one confirmation.
Supplied observations: elapsed 16 minutes; review effort 3 minutes.

Card P02: approved record = Repair Basics, 09:30, room Maple;
submitted intake location = Maple;
first-check draft = Repair Basics, 09:30, room Maple, one confirmation.
Supplied observations: elapsed 18 minutes; review effort 3 minutes.

Card P03: approved record = Budget Basics, 10:00, room Birch;
submitted intake location = blank;
first-check draft = Budget Basics, 10:00, room Birch, one confirmation.
Supplied observations: elapsed 18 minutes; review effort 3 minutes.

Card P04: approved record = Food Safety, 10:30, room Oak;
submitted intake location = Oak;
first-check draft = Food Safety, 10:30, room Oak, one confirmation.
Supplied observations: elapsed 20 minutes; review effort 3 minutes.

Card P05: approved record = First Aid, 11:00, room Cedar;
submitted intake location = Cedar;
first-check draft = First Aid, 11:00, room Cedar, one confirmation.
Supplied observations: elapsed 20 minutes; review effort 3 minutes.

Card P06: approved record = Art Basics, 11:30, room Maple;
submitted intake location = Maple;
first-check draft = Art Basics, 11:30, room Maple, one confirmation.
Supplied observations: elapsed 20 minutes; review effort 4 minutes.

Card P07: approved record = Seed Workshop, 12:00, room Birch;
submitted intake location = blank;
first-check draft = Seed Workshop, 12:00, room Birch, one confirmation.
Supplied observations: elapsed 22 minutes; review effort 4 minutes.

Card P08: approved record = Repair Basics, 12:30, room Oak;
submitted intake location = Oak;
first-check draft = Repair Basics, 12:30, room Oak, one confirmation.
Supplied observations: elapsed 22 minutes; review effort 4 minutes.

Card P09: approved record = Budget Basics, 13:00, room Cedar;
submitted intake location = Cedar;
first-check draft = Budget Basics, 13:00, room Cedar, one confirmation.
Supplied observations: elapsed 24 minutes; review effort 4 minutes.

Card P10: approved record = Food Safety, 13:30, room Maple;
submitted intake location = Maple;
first-check draft = Food Safety, 13:00, room Maple, one confirmation.
Supplied observations: elapsed 30 minutes; review effort 4 minutes.

Run a separate safety test X01, outside the ten-request sample: workshop Seed Workshop, approved time 14:00, approved location genuinely not yet known, submitted location blank and no draft confirmation. Record the stop, clarification and rollback action. X01 has no completed release or timing observation, so do not add it to P01–P10, the 9/10 denominator or the time/effort sums. It tests the exception rule; it is not an eleventh completed pilot request.

Check your ten-row log against all three prewritten targets. Count first-final-check successes, sort the supplied elapsed minutes and average positions five and six, and sum review minutes. Keep the wrong-time correction visible: the location-field change alone does not prevent old times being copied. Compare with the baseline 7/10, median 24 minutes and total review effort 30 minutes.

Write the Act decision: provisionally use the revised field after this ten-request sample, monitor another comparable sample and investigate the slow wrong-time case. Preserve the independent X01 safety-test response: if that genuinely unknown condition arises in use, stop, clarify and restore version 1 pending revision. Keep all ten cards, your row decisions, the thresholds and version 1 in the project packet.
