Read-outRecovered by rework: 120 of 1,000 illustrative garments in a closed inspection cohort (12 percent)

Method and source

Assumed cohort: 1,000 distinct garments with recorded initial inspection outcomes. At cut-off, 820 first-pass accepted plus 120 accepted after rework plus 60 rejected or pending equals 1,000. Final accepted output is 940. Recovery counts garments, not correction events. Pending work is not assumed to be scrap.

Unit: illustrative garments in a closed inspection cohort. Status: illustrative. Illustrative figures are teaching examples, not measured factory results.

The first shift must make evidence as well as garments

A factory without an operating baseline cannot rely on hindsight, so GFT treats measurement as part of production from the outset.

  1. 01 / 05The thesis

    A greenfield garment factory should install a governed, line-level performance-management system from its first shift, because reliable operating evidence is the precondition for control, improvement and any later model.

  2. 02 / 05Part I · The measurement contract

    A greenfield garment factory has no operating history, yet its first shifts create the evidence on which every later forecast, investment case and sustainability claim will depend. This paper argues that the performance-management system must therefore start with production, not arrive after it. GFT's position is simple: capture a small set of well-defined measures at the point of work, …

  3. 03 / 05Part II · Measure the operating system

    … review them on a fixed cadence, and add digital models only when the underlying records are complete enough to support them. The paper builds a measurement architecture for a new cut, make, trim and finishing operation. It connects strategic outcomes to six families: production, quality, delivery, cost, people and sustainability.

  4. 04 / 05Part III · Turn records into decisions

    It defines the operational data behind each family, including good output, downtime, first-pass yield, standard minutes, on-time-in-full delivery, effective labour cost, skills, energy, water and waste. It then specifies source capture, data ownership, measurement-system checks, visual control, daily and weekly reviews, monthly sales and operations planning, and a corrective-action loop.

  5. 05 / 05Part IV · Scale with control

    The final chapters sequence the first eighteen months from clean manual records to active management, structured improvement and a data-driven floor. The result is not a dashboard project. It is an operating discipline that makes performance visible, protects workers from poorly designed targets, and gives later machine-learning applications a defensible database.

Interlude · findings against chapters

10 findings, each argued across the paper.

Finding 01 of 10

Ramp-up must manage learning, yield and production rate together because a new process is initially poorly understood.S11

Finding 02 of 10

A KPI is not ready for a target until its formula, unit, time basis, owner and measurement error are explicit.S01S23S40

Finding 03 of 10

The scorecard should balance financial, behavioural and core-process measures, with both in-process and end-of-process indicators.S02

Finding 04 of 10

OEE is useful only when availability, performance and quality remain visible and downtime retains its causes.S06S07S08

Finding 05 of 10

First-pass yield belongs beside flow and lead-time measures because rework consumes capacity as well as quality.S10

Finding 06 of 10

Standard minutes require a specified method and qualified work, while line balancing remains a daily supervisor task.S03S04

Finding 07 of 10

Supervisor development and fair incentives are production controls, not peripheral human-resources activities.S13S14S16S17

Finding 08 of 10

Source capture needs governed master data, explicit quality checks and shared vocabularies before it can support later models.S21S22S24S25

Finding 09 of 10

Resource intensity is meaningful only with a declared boundary, a production denominator and separate withdrawal, consumption and disposal records.S30S33S34S35S38

Finding 10 of 10

Daily, weekly and monthly routines should reach maturity before history-dependent machine learning is introduced.S27S28S42S44
