This paragraph previews 10.7 · The Analytical Method of Training decomposes sewing into four progressive weeks

Seating an untrained recruit directly onto a live garment assembly line destroys factory utilisation and floods the finishing room with rework.[S31][S35] In a cut-make-trim sewing line where 30 to 41 sequential operations are balanced to a tight cycle time such as 33 seconds per shirt, throughput is governed by the slowest station on the floor.[S31] When a greenfield Cameroonian venture recruits from a labour market where 89.5 percent of workers earn their living in the informal sector and only 5.3 percent of informal tradespeople have attended a formal vocational institution, nearly every entry-level applicant arrives without industrial sewing conditioning.[S12][S42] In Green Future Tech's Cameroon textile programme, prepared on 31 January 2024 with 2026 source refreshes, the engineering answer is strict physical separation between initial skill acquisition and commercial production through an off-line Vestibule Training Centre, or Training Dojo, paired with a live spreadsheet Skill Matrix (illustrative programme design).[S35][S36][S1003]

Operating a dedicated 30-station vestibule dojo allows a greenfield plant to induct cohorts of 30 novices across four-week cycles using the Analytical Method of Training (AMT), graduating operators only after they sustain 65 percent of Standard Allowed Minutes (SAM) with zero critical quality faults across an eight-hour stamina test (illustrative qualification gate).[S35][S37] Evaluations from the International Labour Organization (ILO) and International Finance Corporation (IFC) Better Work programme prove that operators who receive basic skills training reach their daily production targets nearly 15 minutes faster per shift than untrained peers, while structured supervisory training lifts line productivity by 22 percent.[S20][S23][S1001] Across an illustrative 900-person factory employing 720 direct operators over 250 shifts a year, recovering 15 minutes per worker per shift generates 45,000 productive operator-hours a year, equivalent to 22.5 full-time operators at zero extra payroll (derived arithmetic, illustrative estimate).[S20][S1001] Every graduate's machine efficiency and four-tier ILUO grade are recorded in the People Log of GFT's manual Performance-Management System (Deliverable 2), enforcing a 3-by-3 Polyvalence Rule while turning Week 4 of the dojo into a blind assessment centre for local supervisor candidates (illustrative operating system).[S01][S03][S36] All facility specifications, learning trajectories, and budget figures in this chapter are illustrative planning estimates rather than investment, legal, or tax advice.

Why on-line training of novices collapses a balanced garment line

Garment assembly is a serial production system in which human psychomotor consistency dictates plant capacity.[S05][S31] Unlike automated spinning frames or computer-controlled cutting tables, apparel sewing resists full automation because limp woven and knitted fabrics deform under presser-foot and needle-bar forces, requiring human operators to guide plies at every seam.[S05] In an empirical benchmark study of JP Garment Plc in Hawassa, Ethiopia, assembling a long-sleeve woven shirt required 41 workstations operating against a target cycle time of 33 seconds per unit, equivalent to 109 pieces an hour at 100 percent efficiency.[S31] Even with experienced operators, unlevelled task assignments left that baseline line at 67.6 percent efficiency before heuristic line balancing compressed the layout to 30 to 34 stations at 85.9 to 97.35 percent efficiency.[S31]

10.2 The mathematical bottleneck of mixing novices into a paced bundle line

10.2

When managers place raw recruits directly onto a live Progressive Bundle System (PBS) line to learn on the job, the serial mathematics of line balancing turn against the plant.[S31][S32] Suppose a 35-operator shirt line is balanced to a 33-second cycle time (109.1 pieces per hour theoretical capacity) and management inserts three untrained recruits into intermediate operations such as sleeve-placket binding, cuff attachment, and side-seam overlocking (illustrative line scenario).[S31] Because an unconditioned novice requires an illustrative 95 seconds per piece to align plies and control pedal speed, those three workstations process only 37.9 pieces per hour (3,600 seconds divided by 95 seconds, illustrative calculation).[S31][S1002]

S31S32S1002

Within 20 minutes of shift start, two physical failures cascade across the 35-station floor (illustrative mechanism).[S31][S32] Upstream of the first novice, cut bundles pile up at workstation tables, inflating work-in-progress (WIP) inventory.[S31][S32] Downstream of the novices, 20 to 25 experienced operators paid at or above Cameroon's statutory minimum wage (SMIG) of XAF 43,969 a month (about US$76 from 23 February 2024) sit idle for 58 to 62 seconds out of every 95-second cycle waiting for bundles.[R14][S31] Effective line utilisation plunges toward the 33.7 to 48.9 percent utilisation band recorded at Cameroon's state-backed textile incumbent, CICAM, in July 2023, where plant underutilisation cost roughly CFAF 2 billion in 2020.[R12]

Meanwhile, watching bundles stack up beside the table causes the novice to rush pedal strokes before mastering hand-eye coordination.[S35][S1003] Rushed novices generate skipped stitches, broken threads, raw edges, and oil stains that hide inside 30-piece bundles until End-of-Line (EOL) inspection hours later.[S37] Because manual inspection is only 60 to 70 percent accurate and unpicking a sewn seam consumes three to five times more labour minutes than stitching it right the first time, on-line novice placement swamps the mending table and erodes Right-First-Time (RFT) yield (illustrative rework multiple).[R29][S21][S37]

10.3 Why first-generation industrial entrants require off-line conditioning

10.3

This bottleneck is acute in Sub-Saharan African greenfield ventures because recruits are largely new to factory work.[S12][S24] In Cameroon, young people aged 16 to 35 represent 57 percent of the labour force and youth literacy reached 81.8 percent in 2011, yet nearly 70 percent of young jobseekers hold no professional qualification.[S41][S42] National household surveys compiled by the ILO show that 89.5 percent of Cameroonian employment is informal (86.0 percent of men and 93.2 percent of women), split between informal agriculture (48.6 percent) and informal non-agricultural trades (40.9 percent), while industry employs just 13.4 percent of workers.[R16][S42]

¶ 05 · 5 sources

yet nearly 70 percent of young jobseekers hold no professional qualificationS41, S42

S12S24S41S42R16

Even where a recruit has sewn in a neighbourhood workshop, artisanal tailoring habits conflict with industrial cut-make-trim execution.[S35][S42] In Cameroon's informal non-agricultural sector, 66.9 percent of workers learned their trade alone or through hands-on practice and 24.4 percent trained in small informal shops, against 5.3 percent in formal technical and vocational education and training (TVET) establishments.[S42] An informal tailor constructs a whole garment at a single domestic machine without fixed seam allowances or bundle tickets (illustrative craft baseline).[S33][S42] On an industrial line, an operator executes one sub-minute operation hundreds of times a shift at 3,500 to 5,000 revolutions per minute while holding a 1-millimetre seam tolerance (illustrative machine speed).[S31][S35]

S35S42S33S31

Industrial engineering studies warn that when recruits learn unsystematically on the floor, high early turnover follows: motivated learners quit out of frustration while slow workers remain in a cycle of reverse selection.[S24][S27][S1003] Experimental evidence from Ethiopia confirms that most new factory entrants quit within months when rigid pacing and floor friction collide with low initial pay.[S27] Achieving a steady flow of recruits able to meet output and quality standards requires a dedicated facility that follows a systematic off-line training policy.[S35][S1003]

Physical layout and equipment of a thirty-station Vestibule Training Dojo

In Section 5 (Operating Model) and Section 9 (Human Resources Plan) of GFT's Cameroon Feasibility Study, the Vestibule Training Dojo is engineered as a permanent department of the factory rather than a temporary corner of the warehouse (illustrative facility design).[S35][S1003] By isolating initial motor-skill conditioning behind an acoustic glass partition adjacent to the main sewing hall, trainees experience the visual rhythm and professional standards of the plant without obstructing a commercial bundle.[S12][S1003]

10.6 Trainer-to-trainee ratios and Performance-Management System rehearsal

10.6

Line supervisors lack the time and training to coach novices while patrolling 35 live stations.[S35][S1003] GFT staffs the 30-station dojo with one permanent Master Vestibule Instructor (mentored in Phase 0 by GFT's imported Master Quality and Vestibule Trainer) and two full-time Cameroonian Assistant Trainers, establishing a 1-to-10 trainer-to-trainee ratio across a 30-recruit cohort (illustrative ratio).[S35][S1003]

Line supervisors lack the time and training to coach novices while patrolling 35 live stationsS35, S1003

S35S1003

During Week 1 machine-control drills, the three instructors stagger bench rotations so each trainer coaches sub-groups of three to five learners at a time, respecting the industry finding that tight instructor ratios (1:3 during initial needle control and 1:10 during follow-on line support) compress training times, whereas 1:20 rooms cause losses and six-to-eight-week delays.[S1003] Operating on four-week cycles across 48 working weeks a year, a single-shift 30-station dojo inducts 10 to 12 cohorts annually (300 to 360 recruits a year), expanding to 540 trainees a year during Phase 1 and Phase 2 peaks by adding an afternoon shift (illustrative capacity).[R16][S35]

  1. Week 1 (Days 1 to 5): Ergonomics, Autonomous Care, and Unthreaded Paper Control. Trainees begin with occupational safety and health (OSH) conditioning under the ILO Code of Practice, followed by five-minute autonomous maintenance: brushing lint from feed dogs and the rotary hook race, checking the oil-sight glass, and changing needles.[S39][S40] Days 2 to 5 use unthreaded machines at controlled speeds (1,500 to 3,500 rpm) on printed paper sheets: stopping needle-down at corner marks along straight lines, 6-millimetre parallel tracks, squares, S-curves, and spirals (illustrative drill).[S35]
  2. Week 2 (Days 6 to 10): Threaded Cotton Swatch Control and Folder Attachments. Trainees thread their machines and sew cut swatches of SODECOTON-sourced cotton fabric.[R03][S1003] Because needle-running time is only 25 to 35 percent of a sewing cycle while 65 to 75 percent is fabric handling, Week 2 trains motion economy: picking up two plies simultaneously, matching notches without stopping, executing 3-stitch back-tacks, joining curved necklines without puckering, and using hemmer folders and magnetic edge guides to hold a 1-millimetre tolerance (illustrative standard).[S05][S32][S35]
  3. Week 3 (Days 11 to 15): Full Operation Breakdowns, SAM Speed Drills, and TLS Self-Inspection. Each trainee learns two primary operations from GFT's ready-to-wear and uniform styles (such as single-needle collar topstitching and four-thread overlock shoulder joining) plus one secondary machine class.[S31][S36] Trainees sew 10-piece and 30-piece bundles against stopwatch SAM targets while inspecting their own first and last pieces against the 40-defect visual lexicon under the inline Traffic Light System.[R29][S35][S37]
  4. Week 4 (Days 16 to 20): Stamina Runs, PMS Log Simulation, and Supervisor Diagnostic Trials. Week 4 builds stamina through continuous runs: 1 hour on Day 16, 2 hours on Day 17, 4 hours on Day 18, and a full simulated 8-hour shift on Day 19 (illustrative stamina protocol).[S35][S1002] To graduate on Day 20, the trainee must sustain at least 65 percent SAM efficiency across the 8-hour test with DHU below 4.0 and zero Red TLS cards, while top-quartile performers complete the two-day mini-line leadership trial.[S01][S36][S37]

The sequence in Exhibit 39 ensures that no recruit touches commercial fabric until motor control and machine care are established in Week 1, and no recruit enters a live line until 8-hour stamina and secondary-machine cross-training are verified in Week 4 (illustrative gate).[S35][S1003] While this 20-day schedule is an illustrative planning norm for first-generation recruits, RPL fast-track candidates compress Weeks 1 and 2 into five days, graduating in 15 days.

Two operational differences stand out in Exhibit 40. First, during Weeks 1 to 4, when the unstructured recruit drags a live line down to 14 to 32 percent efficiency, the Vestibule AMT trainee is inside the off-line dojo climbing from 22 to 65 percent efficiency on practice swatches without costing the main floor a single minute of balancing loss (illustrative trajectory).[S31][S35][S1002] Second, when the Vestibule AMT graduate steps onto a live line in Week 5 at 65 percent efficiency supported by a 1-to-10 transition trainer and a trained supervisor, she crosses the 75 percent target band by Week 6 and reaches 85 to 87 percent by Weeks 10 to 12, whereas the uncoached worker plateaus near 60 percent at Week 12.[S20][S35][S1003] Because this trajectory is a derived planning curve rather than a forecast for every individual, GFT tracks actual cohort curves weekly in the Capacity and Utilisation Ramp Planner (ramp-planner).

Empirical evidence on basic skills training shows fifteen minutes faster daily target attainment

The financial case for funding an off-line vestibule dojo and shop-floor trainers rests on econometrics from global garment supply chains.[S20][S1001] Since 2007, researchers at Tufts University have conducted independent impact assessments of the joint ILO and IFC Better Work programme, analysing nearly 15,000 survey responses from garment workers and 2,000 responses from factory managers across Haiti, Indonesia, Jordan, Nicaragua, and Vietnam.[S20][S1001]

10.12 Econometric proof from Better Work and ILO SCORE evaluations

10.12

The Tufts impact assessment isolated the direct effect of structured worker and supervisor training on daily output speed.[S20][S1001] Garment workers who participated in basic skills training reached their daily production targets on average nearly 15 minutes faster every shift than workers who had not participated.[S20][S1001] When basic operator training was combined with Better Work's three-day Supervisory Skills Training (SST), lines overseen by trained supervisors achieved a 22 percent increase in productivity relative to lines managed by untrained supervisors, alongside fewer unbalanced line pile-ups, lower turnover, and lower injury rates.[S20][S22][S23][S1001]

Conversely, workers concerned about verbal abuse from untrained supervisors took almost one extra hour per day to reach their production target, even after controlling for education, training, and experience.[S20][S1001] Over four years in Better Work Vietnam, improvements in training and working conditions raised the average factory's revenue-to-cost ratio by 25 percent (a cumulative effect of 0.62 on a mean ratio of 2.48).[S1001] Similarly, the ILO's Sustaining Competitive and Responsible Enterprises (SCORE) programme across Brazilian sewing workshops monitored by SENAI found that shop-floor cooperation and quality training raised average productivity by 15 percent and cut rework rates by 12 percent.[S21]

10.13 Arithmetic of the fifteen-minute daily gain across a 720-operator floor

10.13

In a greenfield Cameroonian factory governed by a standard 40-hour working week (480 minutes per shift across five days, up to a 48-hour maximum with overtime at 1.2 times base pay), saving 15 minutes per operator per shift alters unit economics through three channels.[R16][S20][S1001] First, 15 minutes out of a 480-minute shift recovers 3.125 percent of total paid shift time into good garment output (derived arithmetic).[R16][S1001] Second, finishing the daily target 15 minutes earlier eliminates chronic end-of-shift overtime at the 1.2x statutory premium.[R16][S20] Third, operators who hit their target inside standard hours qualify consistently for GFT's yield-gated efficiency bonus (Chapter 12), raising earnings above the XAF 43,969 monthly SMIG floor and curbing early quitting.[R14][S24][S27]

Method and source

Derived arithmetic applying the ILO/IFC Better Work finding of nearly 15 minutes (0.25 hours) faster daily target attainment from basic skills training (S20, S1001) across 250 eight-hour shifts per year (R16) for GFT's illustrative Phase 1 (240 operators), Phase 2 (480 operators), and Phase 3 (720 operators) workforce.

Unit: productive operator-hours recovered per year. Status: derived. Sources: R16, S20, S1001.

As Exhibit 41 shows, the 45,000 operator-hours recovered annually at full ramp exceed the 38,400-hour annual training time spent by 240 new recruits passing through 160-hour Vestibule AMT cohorts (240 * 160 = 38,400 hours, derived comparison).[S20][S1001] A trainee's stipend during vestibule training is minor compared with the overhead recovery gained by compressing the learning curve on the live floor.[S1003] While the 15-minute empirical benchmark was measured in Vietnamese Better Work factories rather than Cameroon, GFT uses it as a calibration anchor alongside local stopwatch audits in the Garment Unit-Economics Simulator (unit-economics).[S1001]

  • Level I (Learner / In-Training, 40 to 59 percent efficiency): Understands machine threading, safety rules, and basic seam geometry from Week 2 or Week 3 dojo drills, but requires oversight and cannot yet hold line pitch independently.[S35][S36]
  • Level L (Licensed Practitioner, 60 to 79 percent efficiency, DHU below 5.0): The minimum graduation standard from Week 4 of the Vestibule Dojo (>=65 percent on the primary operation). Executes the operation independently on a live line with zero Red TLS cards.[S36][S37]
  • Level U (Unassisted Mastery, 80 to 94 percent efficiency, RFT at or above 97 percent): A Grade-A operator who beats standard SAM across style changeovers while maintaining Green TLS status, eligible for bottleneck assignment and Band 2 progression.[S31][S36][S37]
  • Level O (Operational Coach / Master, 95 percent or higher efficiency, RFT at or above 98.5 percent): Certified to run the station at peak pace, demonstrate motion economy to peers, relieve the Assistant Line Leader, and enter the supervisory assessment track.[S22][S35][S36]

The three-by-three polyvalence rule insulates lines against absenteeism and style shifts

In Section 3 (Six KPI Families) of GFT's Performance-Management System Design, the People family is restricted to two actionable metrics: daily absenteeism and skill-matrix coverage. Reviewing absenteeism and skill-matrix coverage together every week prevents morning absences from stalling a sewing line.[S04][S36]

Station Depth (Three operators per operation): Every operation in a sewing line's Operation Breakdown must have at least three operators assigned to that line certified at ILUO Level L (60 percent efficiency) or higher on that operation, including at least one backup certified at Level U (>=80 percent).[S31][S36]
  2. Operator Breadth (Three operations across two machines per operator): Every direct sewing operator with six or more months of factory tenure must be certified at Level L or higher on at least three distinct operations spanning at least two different machine families.[S36][S1004]

Line-level skill-matrix coverage is calculated in the People and Sustainability sheet as the percentage of stations satisfying the three-operator depth rule and active operators satisfying the three-operation breadth rule (target >=85 percent coverage by the end of Phase 1 and >=92 percent in Phases 2 and 3, illustrative KPI gate).[S36]

10.19 How 3-by-3 polyvalence enables five-minute morning cascade rebalancing

10.19

Consider the morning attendance shock analysed by National Bureau of Economic Research (NBER) researchers in Working Paper 25865.[S04] Across developing-country garment plants, daily unscheduled absenteeism routinely runs between 4 and 9 percent.[S06][S24] On a 35-operator progressive bundle line, a 6 to 8 percent morning absence means two or three machinists are missing when the shift bell rings at 07:45 (illustrative shift scenario).[S04][S31]

…(NBER) researchers in Working Paper 25865S04

On a single-skill line, an absent collar-band or bar-tack machinist shuts down the bottleneck station for hours.[S31] On a GFT line holding >=85 percent 3-by-3 coverage, the supervisor opens the People Log lookup table at 07:45 during the 15-minute pre-shift check and executes a three-step cascade swap in under five minutes (illustrative rebalancing protocol):[S04][S36][S1004]

  • Step 1 (Cover the critical bottleneck with a Level U/O backup): If the absent worker occupied a Grade-A bottleneck station (such as Collar attach in Exhibit 42), the supervisor shifts OP-01 (Floater at 96 percent efficiency) or OP-03 (91 percent on collar) into the collar station.[S04][S36]
  • Step 2 (Backfill the intermediate station with a cross-trained Level L operator): The station vacated by the moved operator is filled by a cross-trained operator from a non-bottleneck task holding a secondary Level L/U certification (OP-08 or OP-09).[S04][S36]
  • Step 3 (Absorb the remaining gap at the lowest-SAM prep task): The final opening is pushed to the simplest Grade-C prep operation (such as pocket hemming or label tacking), where a recent vestibule graduate can hold flow or the IE technician can combine two short tasks within the 33-second pitch ceiling.[S31][S32]

Empirical econometrics confirm that supervisors who dynamically reassign workers to tasks where they perform best during shocks shield the line from sharp output drops.[S04] Equally important, when the factory switches styles between woven shirts, jersey T-shirts, and institutional uniforms (Feasibility Study Section 2), a workforce cross-trained across lockstitch and overlock/flatlock machines reconfigures in a single shift.[S31][S36]

10.20 · Introduction · paragraph 1 of 9

The Vestibule Training Dojo performs a second strategic function: it acts as GFT's blind, objective assessment centre for selecting local Cameroonian line supervisor trainees from within the operator cohort.[S01][S03][S22]

10.21 Why subjective manager nominations fail and suppress female leadership

Relying on middle managers' informal impressions to pick supervisor trainees is empirically broken on two counts.[S01][S02][S03] First, in a randomised field study across garment factories by researchers at the National University of Singapore (the STITCH evaluation), researchers asked Factory and Floor Managers (FFMs) to rank which line supervisors they recommended for structured training before randomising training across all candidates.[S02][S03] While treated supervisors raised line productivity by 7.3 percent during training and 5.8 percent six months later overall, supervisors highly recommended by middle management showed nearly zero productivity gain from training, whereas supervisors given low recommendation rankings by management achieved productivity jumps of more than 11 percent.[S02][S03]

Second, traditional factory nominations perpetuate gender exclusion on the garment floor.[S01] In the Bangladeshi garment sector evaluated by University of Warwick researchers, nearly 80 percent of production line operators were women, yet 95 percent of line supervisors were men because workers and managers held biased beliefs against female candidates prior to objective diagnostics.[S01] Yet independent evaluations of the ILO and IFC Better Work programme prove that production lines overseen by Supervisory Skills-trained female line supervisors achieved a 22 percent increase in productivity compared with lines run by untrained supervisors.[S20][S23] In Cameroon, where 93.2 percent of working women are in the informal economy and 86.9 percent face underemployment, opening an objective promotion pathway from the sewing machine to line supervision is both an operational imperative and a major socioeconomic upgrade.[S33][S42]

10.22 The Week 4 blind leadership diagnostic trial in the Vestibule Dojo

To eliminate favouritism and gender bias from Phase 0 onward, GFT embeds a mandatory two-day Simulated Mini-Line Leadership Trial inside Days 19 and 20 of every four-week Vestibule Dojo cohort (illustrative assessment protocol).[S01][S22] Every operator trainee, female or male, who achieves ILUO Level L/U (>=70 percent efficiency with zero Red TLS cards) by Day 18 and scores in the top quartile on a 20-minute written numeric and pattern-logic test is automatically entered into the leadership trial without requiring a manager's nomination.[S01][S03]

During the trial, the dojo's 30 stations are partitioned into five 6-station micro-lines assembling a standard five-operation garment component.[S31] Each candidate rotates through a two-hour shift as Acting Line Leader of a 6-station loop while two master trainers and the HR Lead score performance blind across four observable shop-floor behaviours, detailed in Exhibit 43:[S01][S03][S22][S31]

As shown in Exhibit 43, the four exercises test the exact daily habits required by GFT's Performance-Management System (Deliverable 2, Sections 4 and 5).[S22][S31] Exercise 1 tests whether the candidate notices physical bundle accumulation and applies pitch-time reasoning (30 percent weight).[S31] Exercise 2 tests constructive pedagogy under time pressure, screening out candidates prone to the verbal hostility that costs lines nearly an hour a day in Better Work studies (30 percent weight).[S20][S22][S1001] Exercise 3 verifies arithmetic accuracy for the daily Line Log and Quality Log (20 percent weight), and Exercise 4 tests structured communication at the visual board (20 percent weight).

Candidates who score 75 points or higher out of 100 are tagged with code SUP-CAND in the People Log Skill Matrix and promoted into Assistant Line Leader trial rotations and the 120-hour GFT Supervisory Skills and Engineering Curriculum (Chapter 11), with a governance floor requiring at least 60 percent of supervisory trainee slots to be filled by qualified women (illustrative target).[S01][S23] While a dojo simulation cannot replicate every pressure of a 35-person line over a full year, combining objective Week 4 diagnostics with a 90-day Assistant Line Leader floor probation ensures promotion on measured evidence.

10.23 Connecting the Vestibule Dojo to the eighteen-month factory ramp

Across all three deliverables of GFT's Cameroon textile programme, the Vestibule Training Dojo and the ILUO Skill Matrix form the physical valve that regulates factory scale (Feasibility Study Sections 9 and 12; PMS Deliverable 2 Sections 3, 4, and 7). During Phase 0 setup (Months -4 to 0), the 30-station dojo is commissioned four months before commercial sewing lines start, so Cohort 1 operators, Assistant Line Leaders, and local shadow supervisors graduate and populate the initial People Log database ahead of Gate 0-to-1 (illustrative rollout sequence).[S35][S36]

During Phase 1 (Months 1 to 6, 8 lines, 240 operators) and Phase 2 (Months 7 to 12, 14 lines, 480 operators), the dojo runs continuous four-week morning induction cycles to staff each new pair of sewing lines while dedicating afternoon sessions to 3-by-3 polyvalence cross-training and remedial coaching for any operator whose weekly efficiency dips below 65 percent.[S35][S36][S1003] By Phase 3 (Months 13 to 18, 20 lines, 720 operators, 3.0 million garments a year), when recruitment shifts to replacing normal attrition (held below an illustrative 15 percent annual target), the dojo transitions into a permanent continuous-improvement, style-changeover pre-production, and supervisory assessment laboratory.[S24][S35]
