Choose a useful next increment
Which work fits the available days and addresses observed failures?
Entering midway? Revisit Where should the team improve? for the preceding worked example, or start here and use the explanation below.
Start with a concrete question
Three whole jobs address disjoint fictional task failures. A chosen priority order accepts each job that fits remaining capacity.
Try the initial inputs, then write a prediction before changing one setting. All calculations run locally on your CPU.
What do you expect?
Before changing a setting: Which work fits the available days and addresses observed failures? Write what you expect and why.
Change one thing. Inspect what happens.
- Compare orders with five days available.
- Inspect the evidence supporting each job.
- Increase capacity to ten days.
- Write an increment plan with acceptance cases and a reason for each deferred job.

Compare the current results
Every bar starts at zero and uses the same numeric scale in this chart. The upper bound automatically adjusts to the largest current value (at least 1), so compare the numbers when changing inputs. Units and quantities come from each label; different kinds of quantity are not interchangeable. Displayed values are rounded to at most six significant digits.Follow the calculation
- keyboard form repair: 3 work-days, 12 distinct observed failures; selected.
- clearer resume label: 2 work-days, 8 distinct observed failures; selected.
- new gallery: 5 work-days, 3 distinct observed failures; deferred.
- Failure sets do not overlap. Each selected repair resolves exactly its listed fixture cases; real repair effects need retesting.
Prioritize against a goal and finite capacity. Popularity or visual novelty is not the same as observed user need.
Captures keep your inputs, prediction and observation. Results are recalculated from those inputs. Resetting inputs keeps your captures and challenge history.
Explain the mechanism
Choose a useful next increment
Three whole jobs address disjoint fictional task failures. A chosen priority order accepts each job that fits remaining capacity.
Follow the mechanism
The access and label repairs together use five days and address twenty fixture failures.
The gallery uses five days and addresses three fixture failures.
Actual benefit requires retesting; observed counts do not capture every strategic or ethical consideration.
Worked example
keyboard form repair: 3 work-days, 12 distinct observed failures; selected.
clearer resume label: 2 work-days, 8 distinct observed failures; selected.
new gallery: 5 work-days, 3 distinct observed failures; deferred.
Failure sets do not overlap. Each selected repair resolves exactly its listed fixture cases; real repair effects need retesting.
Calculation
Remaining capacity = available days − accepted job days; addressed cases sum disjoint repaired failure sets.
Try a controlled comparison
Compare orders with five days available.
Inspect the evidence supporting each job.
Increase capacity to ten days.
Write an increment plan with acceptance cases and a reason for each deferred job.
What this does not establish
- All messages, people, documents and outcomes here are original fictional teaching fixtures; results are not measurements of real organizations.
Try a fresh case
A five-day budget funds a three-day repair and a two-day repair addressing 7 and 9 distinct cases. How many cases are addressed?
This is a public practice check. Retries support learning; matching a number does not certify independent proficiency.
Take the investigation further
Choose any extension. These are project prompts for you to carry out; they are not automatically assessed.
School investigation
Create a new case with different numbers and explain your decision to a classmate.
College investigation
Implement or analyze a fresh case, document assumptions and compare at least two alternatives.
Workplace investigation
Prepare a decision artifact with evidence, operating constraints, an owner and a follow-up measurement.
Keep the evidence, choose your next step
Completion records your own decision that you have worked through this investigation. Practice checks and independent project evidence are separate.
