Read pilot results without overstating certainty
See this course’s project requirements
Collect and revise all six lesson outputs into a fictional process-improvement plan. Show how the process works now, starting measurements, a possible cause of the problem, a Plan-Do-Check-Act test, a review of the results, and checks to keep the improvement working. Label it as fictional practice.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Map the bounded current process with decisions and rework.
- Calculate baseline capacity, elapsed time and first-pass accuracy.
- Document a cause hypothesis and one targeted improvement.
- Plan, perform and evaluate the supplied ten-request paper PDCA test against predefined measures; preserve the row-level record and the separate unknown-location exception test.
- Assemble a control plan with ownership, triggers and a response to a failing sample.
Review and revise
Use these criteria to check your work and choose what to improve.
- Accuracy: amounts, classifications and decisions agree with the supplied evidence and stated assumptions.
- Reasoning: each important choice names the rule, observation or comparison that supports it.
- Responsible scope: the packet protects information, respects authority limits and routes unresolved concerns appropriately.
- Usability: a new reader can follow the ordered lesson outputs, identify ownership and see what is complete or still uncertain.

The idea in everyday life
A pilot result can be promising without proving that the process will behave the same way everywhere. Compare the agreed measures, check whether the sample conditions changed and record both benefits and costs. A median describes the middle of a set, not its worst case. Review the individual observations so an attractive summary does not hide important exceptions.
Judge the whole prediction and keep sample limits visible.
One step at a time.
Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.
- 1
Order each set of elapsed times and calculate the median as the average of the fifth and sixth values. Keep the raw values beside the summary so the longest case remains visible.
- 2
Calculate pilot first-pass accuracy and compare it with the baseline using percentage points. State that 90% minus 70% is a 20-percentage-point improvement in these samples.
- 3
Compare review effort with the prewritten threshold and name the five-minute increase. Evaluate all three criteria rather than declaring success from the most favorable measure alone.
- 4
Write an Act decision proportional to the evidence: provisional use with another comparable sample. Identify the slow case and possible differences in request mix as reasons for further review rather than claiming a guaranteed causal effect.
See how it works.
Fictional practice: Fern’s baseline elapsed times for ten requests are 20, 20, 22, 22, 24, 24, 26, 26, 28 and 28 minutes; the median is 24. Pilot times are 16, 18, 18, 20, 20, 20, 22, 22, 24 and 30; the median is 20. Nine of ten pilot confirmations pass initially, giving 90%, compared with 70% at baseline. Review effort rises from 30 to 35 minutes. All stated pilot targets are met, but the 30-minute case still needs review and the ten-request sample is small. The coordinator provisionally keeps the change while collecting another comparable sample.
Did you cover these?
- Baseline and pilot medians are 24 and 20 minutes.
- Accuracy changes by 20 percentage points, with review effort up five minutes.
- The slow case and small-sample limits remain visible.
What to finish
A pilot evaluation with medians, accuracy comparison, workload tradeoff and provisional decision.
Watch for this
Reporting a median improvement as proof every request became faster.
