This page shows a merchandiser, production manager, or buyer how to record and read one improvement idea's progress on the continuous-improvement idea tracker, so a claim that an idea "is working" can be checked against its recorded stage, not against an impression. A person who has already run a small kaizen cycle (lesson 5.3) still needs to know when that cycle's result may be reported as a fact.
This matters to Mona, the merchandiser at Delta Garments, who reports Order A's line to Sara, the buyer at Northline Apparel; to Karim, the production manager who owns the ideas being trialled; and to any manager tempted to call a change an improvement before it has been measured. Sara has asked Mona for evidence that Delta Garments' claimed floor improvements are real.
Without this skill, a manager reports an idea as proven because operators say it feels faster, while the tracker's before and after columns stay blank. This lesson gives you the four-stage rule an idea moves through, the method for recording it, and the reason "Trial" is not yet a result.
You need: lesson 5.3 (Kaizen versus one-off projects), and it helps to already know the seven named waste categories (lesson 5.2), since every tracked idea names the waste type it targets.
By the end of this lesson you can:
Not covered here: value-adding activity against waste (lesson 5.1), the seven wastes (lesson 5.2), kaizen versus a one-off project (lesson 5.3), and a complete tracker covering several ideas (lesson 5.5).
| Term | Meaning |
|---|---|
| Root-cause analysis | Asking why a problem happened repeatedly until the real underlying cause is found, instead of fixing only its first visible symptom. |
| Kaizen | A small, low-cost improvement made by the people who do the work, tried and measured quickly, instead of a large one-off project planned and installed by someone else. |
| The seven wastes (muda) | The seven named categories of non-value-adding activity a lean factory looks for: transportation, inventory, motion, waiting, overproduction, overprocessing and defects. |
| Standard work | The one best-known way to do an operation, written down and followed by every operator doing that operation, so an improvement can be measured against a fixed starting point. |
| Gemba walk | Going to the actual place where the work happens — the sewing floor, not the office — to see a problem directly before deciding how to fix it. |
Tracking a single improvement idea means recording it at every stage it passes through — proposed, tried, measured, then adopted or rejected — with a stated before metric and after metric for the same thing, so the idea's effect is shown by a comparison, not claimed by opinion. An idea still marked "Proposed" or "Trial" has not yet been proven to work, no matter how promising it looks on the floor, because no comparison between a before state and an after state has yet been recorded for it.
| What can differ | The shapes you will meet | Why it matters |
|---|---|---|
| Proposed | The idea is written down with the waste type it targets (lesson 5.2) and an owner, but nothing has been tried yet. | An idea recorded only as "Proposed" carries no evidence at all; it is a plan, not yet an action. |
| Trial | The idea is tried on a limited scale — one station, one shift, one bundle run — so its effect can be observed before the whole line commits to it. | A trial shows the idea is being tested, not that it has already worked; the before and after metrics are often still blank at this stage. |
| Measured | A before metric and an after metric for the same thing — the same station, the same operation, the same shift length — are both recorded, showing whether the trial actually changed the outcome. | This is the first stage at which a comparison exists; without both metrics recorded for the same thing, there is nothing to compare. |
| Adopted or Rejected | Based on the measured result, the idea is either adopted for the whole line and becomes part of standard work, or rejected, with the tracker recording why. | Closes the loop: a proven idea becomes the new way of working; a disproven idea is kept on record so it is not tried again unremembered. |
| A domestic, Make to Stock order, such as Cedar & Co.'s own shape | The same four stages apply in the same order: an idea proposed for a domestic line still needs a trial, then a measured before/after comparison, before it is adopted or rejected. | Confirms the tracking rule does not depend on export or domestic, or on MTO, MTS or a hybrid order; it depends only on whether a comparison has been recorded. |
Sara, the buyer at Northline Apparel, asks Mona, the merchandiser at Delta Garments, for evidence that the factory's claimed floor improvements on Order A's line are real, not just described in conversation. Mona pulls up the continuous-improvement idea tracker's entry for the trim-tray idea, first raised as a kaizen cycle in lesson 5.3: moving trims closer to the neck rib attach station to reduce reaching motion. The tracker's own row currently reads status "Trial," with the before metric and after metric columns both still blank, since the trial has only just started on Karim's own station.
The worked numberThis lesson's worked output is not a specific academy figure; it is reading what a tracker entry actually shows. The trim-tray idea's row reads: waste type "Motion," owner "Karim," status "Trial," before metric and after metric both still blank.
A common mistake is telling a buyer or manager that a change "is working," based on impression alone, while the tracker's own before metric and after metric fields are still blank. This is the same error as lesson 7.3.5's verbal "sewing is done" claim made without checking the tracker's own bundle record, applied here to a continuous-improvement claim instead of a production claim; in both cases, a spoken impression is reported as fact while the factory's own record shows the comparison has not yet been made.
Tracking an improvement idea means writing down what happens to it at every step: first the idea itself and who owns it, then whether it has actually been tried yet, then whether it has been measured before and after, and finally whether it worked well enough to keep. An idea that has only been thought of, or only just tried on one station, is not yet proven, even if it looks promising. It becomes proven only once someone measures the same thing twice, once before the change and once after it, and compares the two numbers. Telling someone the change is already working, before that comparison exists, is describing a hope as if it were already a fact.
Mona, the merchandiser at Delta Garments, is preparing to update Sara, the buyer at Northline Apparel, on Order A's line.
The document Mona reads before writing to Sara:
Should Mona tell Sara the trim-tray change is already proven to be working? Decide before opening the answer.
No. The tracker's own record shows the idea is still at "Trial" with no before metric and no after metric recorded, so there is no measured comparison for Mona to point to.
First fact. The idea's status column reads "Trial," one stage short of "Measured," meaning it has only been tried on a limited scale, not yet compared before and after.
Second fact. Both the before metric and after metric fields are blank on the tracker's own row, so no number exists yet to show whether reaching motion at neck rib attach actually changed.
Mona should tell Sara that the trim-tray idea is being trialled and will be reported once both metrics are measured and compared, rather than claiming a result the tracker does not yet show. Reporting the change as already proven, based only on operators' informal comments, risks Sara relying on a claim that may not hold up once the real before/after comparison is made.
Framed qualitatively, since this lesson is about reading a tracker record rather than a costing exercise: reporting an unmeasured idea as a proven improvement risks Sara relying on a claim that later turns out not to hold up once the actual before/after comparison is made. If the measured result later shows little or no change, or even a worse outcome, Sara has already carried an incorrect claim into her own reporting at Northline Apparel. The damage is not limited to one idea: it risks the credibility of every future improvement report from Delta Garments, the same trust cost lesson 7.3.5 describes for a verbal "sewing is done" claim made without checking the tracker's own bundle record.
Open the Continuous-improvement idea tracker. For the trim-tray idea, its "Waste type targeted" and "Idea owner" columns are already recorded from when it was first proposed; fill in the "Before metric" and "After metric" columns only once the trial has actually run long enough to observe a result, using the same unit and the same station for both. Update the "Idea status" column from "Trial" to "Measured" once both metrics are recorded, then to "Adopted" or "Rejected" based on the comparison.

1. What are the four statuses an improvement idea moves through on the tracker?
2. In the worked scenario, why should Mona not tell Sara the trim-tray change is already proven to work?
3. A different line records a waiting-time idea with before metric "14 minutes per bundle" and after metric "9 minutes per bundle," both measured at the same station on the same shift, with status still showing "Trial." What should the status be updated to next?
