Many garment factories try to fix efficiency before they fix quality. That order usually fails.
Operator Work Efficiency (OWE) looks strong when rework is hidden. Pieces move, machines run, and the line appears busy. Then finishing, inspection and packing reveal the real cost.
RFT is not a quality department metric alone
Right First Time (RFT) is a production control number. It tells you whether the line is building shippable output or creating hidden work.
When RFT drops:
- Rework loops steal capacity.
- Supervisors chase defects instead of flow.
- Dispatch dates slip quietly.
- Buyer pressure increases on the wrong orders.
The efficiency illusion
A line can show acceptable output with weak RFT because:
- Extra operators are absorbed in repair.
- Inspection is catching problems late.
- Rework is happening off the main tracking path.
- Defects are passed to the next section.
This is why factories sometimes “improve efficiency” and still miss OTIF.
Build quality gates at the right points
You do not need inspection at every step. You need inspection where defects become expensive:
- After the first critical operation.
- Before section transfer.
- Before finishing entry.
- Before packing if buyer history shows repeat issues.
Each gate should answer one question: Can this bundle move forward without creating rework downstream?
Connect RFT to daily review
Add RFT trend to the morning control board, not only to the monthly quality report.
Review:
- Top three recurring defects.
- Operation responsible.
- Whether the defect is skill, machine, method or material.
- Action owner and deadline.
If RFT is red, do not celebrate OWE.
Supervisor habits that help
- Stop the line briefly for a defect cluster.
- Show the defect sample to all operators on the operation.
- Re-verify machine setting and attachment.
- Record the fix and check the next 50 pieces.
Small stoppages are cheaper than finishing rework.
Where SewTrak and transformation work fit
Live tracking makes quality and output visible together. Transformation work helps install the daily review rhythm, SOP mini-packs and supervisor coaching that keep RFT from drifting.
Navvi action: If RFT is hurting delivery and profit, start with a factory assessment. Navvi maps loss, installs control points and connects KPI visibility through dashboards and SewTrak where needed.
