A performance measure changes factory behaviour only when it arrives at a scheduled forum where a named role holds both the authority and the resources to act on it.[S02][S22] Chapter 10 established that a greenfield cut, make, trim and finishing plant needs one governed record linking source events, master data and quality controls. Yet even a complete operational record remains passive if managers inspect it only when a shipment is already late or an accounting period has closed. In GFT's operating design, the management cadence is the active mechanism that converts validated records into owned decisions. Daily shift huddles protect current-day flow within the sewing line's authority, weekly plant reviews remove recurring cross-functional constraints, and monthly sales and operations planning (S&OP) reconciles aggregate product-family demand against demonstrated capability rather than nameplate assumptions.[S04][S08][S42] Each forum operates on a defined horizon, reads from the same authoritative record, escalates exceptions along explicit decision rights, and tracks every agreed intervention in a persistent action log until its operating effect is verified.[S22][S43][S44]
Without a fixed review architecture, a greenfield garment factory falls into two opposite failure modes. In the first mode, supervisors spend their shifts firefighting bundle shortages, thread breaks and rework loops through informal conversations that leave no institutional trace, while senior management reviews monthly summaries that arrive too late to save affected orders.[S02][S1103] In the second mode, the plant proliferates meetings where every tier debates the same raw numbers from competing spreadsheets, turning line leaders into report compilers rather than floor coaches while still failing to resolve who owns a capacity conflict.[S22][S1102] GFT avoids both traps by treating the review calendar as an engineered control system. Just as ISO 22400 requires every key performance indicator (KPI) to specify its formula, unit and time behaviour, GFT requires every review forum to specify its input indicators, decision boundary, escalation threshold and verification rule before production begins.[S01][S44]
The architecture of this cadence is summarised in Exhibit 50, which maps the factory's review forums across two analytical dimensions: the planning horizon under review and the scope of resource-reallocation authority held by the chair. Intra-shift visual checks and daily line huddles sit in the short-horizon, local-authority quadrant, where the supervisor can rebalance stations, deploy a utility operator or request immediate mechanic attendance.[S04] Cross-line coordination and weekly plant reviews occupy the intermediate zone, where operations, quality, maintenance and human-resources leaders reallocate shared technicians, authorise root-cause investigations and adjust training schedules.[S08][S14] Monthly S&OP and quarterly governance audits sit in the upper-right zone, where executive leadership reconciles product-family order books, material procurement windows, shift structures and method or capital changes.[S42][S44]
Exhibit 50 clarifies why a single meeting cannot govern a factory. If a daily shift huddle attempts to renegotiate customer delivery dates, it paralyses the line; if a monthly executive committee attempts to diagnose why a single overlock station lost twenty illustrative minutes on a Tuesday morning, it drowns in operational noise while leaving next quarter's fabric and skill bottlenecks unaddressed.[S07][S42] The lower-right quadrant represents a structural anti-pattern: forums that review multi-week forecasts without holding the authority to adjust capacity, materials or commercial commitments generate commentary rather than control.[S44] What Exhibit 50 cannot establish on its own is whether a plant's supervisors and managers have acquired the practical coaching skills required to exercise their assigned authority; that behavioural readiness must be developed through structured workplace practice and verified through routine meeting audits.[S13][S14][S44]

11.1 · the bodyThe film above follows these sub-steps.
The daily shift huddle is the foundational operating routine on the garment floor because it connects yesterday's verified record to today's immediate station allocation. Garment-sector improvement programmes documented by the International Labour Organization (ILO), such as the Sustaining Competitive and Responsible Enterprises (SCORE) methodology in Ethiopia, begin with a baseline assessment to identify operational gaps and then measure change systematically through KPIs.[S05] A baseline assessment, however, only produces sustained factory improvement when frontline teams review those KPIs at the start of every working day and translate observed gaps into concrete shift adjustments.[S05][S1101] In a NIST Manufacturing Extension Partnership (MEP) case study of a lean daily management system, aligning employees from the shop floor to senior leadership relied on deploying policy scorecards, visual controls, regular huddle-board meetings and daily floor walks to build personal ownership of performance data.[S1101] GFT adapts this discipline to a greenfield sewing, cutting and finishing operation, where high operator density and frequent style transitions make single-shift drift expensive.
To protect production time, GFT designs the line-level huddle as a standing meeting held directly in front of the physical or digital line board at shift start, bounded to an illustrative duration of 10 to 12 minutes. A huddle that exceeds 15 illustrative minutes either is attempting engineering root-cause analysis that belongs offline, or is suffering from unprepared source records that force participants to argue over what happened on the prior shift.[S22][S1102] The line supervisor chairs the meeting with the line's quality inspector, assigned maintenance liaison, bundle handler and operator representatives. Because the authoritative record from Chapter 10 closes and validates the prior shift's logs before handover, the supervisor arrives with reconciled figures rather than unverified tally marks.[S01]
The agenda proceeds through five mandatory checks in fixed order:
In apparel manufacturing, the daily huddle is the forum that executes daily line balancing. ILO evaluation of the Factory Improvement Toolset across Asian garment factories emphasises that line balancing is performed systematically by line supervisors both before production through planning and daily during production.[S04] Pre-production balancing uses the operation breakdown and standard minute values (SMVs), which represent the time value for a task based on the average output rate that qualified workers naturally achieve without over-exertion when adhering to the specified method.[S03] On a real shift, however, two operators may be absent, a new style cohort may be in its second week of ramp-up where the process remains imperfectly understood, or a specific seam may be generating stitch-density defects that slow the station below its normative SMV.[S03][S11]
During the huddle and the opening hour of the shift, the supervisor uses the skill matrix and the prior shift's operation-level output record to rebalance work across stations.[S04] Within line authority, the supervisor can split a bottleneck operation across two qualified operators, assign a multi-skilled floater to cover an absent station, adjust bundle release pacing to prevent WIP accumulation ahead of a slower learner, or request a workstation guide attachment from the line mechanic.[S04][S14] What the supervisor must not do is alter the approved construction method without industrial-engineering sign-off, waive an inline quality inspection standard to clear a queue, or compel operators to work unrecorded hours to mask a balancing deficit.[S03][S18][S45]
A fixed huddle agenda fails if supervisors treat variance review as public blame. A randomised impact evaluation by the International Finance Corporation (IFC) in the Cambodian garment industry found that supervisory skills training improved workers' perceptions of relationships with their supervisors and led to moderate improvements in overall firm productivity.[S13] Similarly, a 2025 IFC and ILO Better Work assessment of the Gender Equality and Returns (GEAR) programme in Bangladesh documented that effective supervisor development combined classroom sessions with six to eight weeks of structured line shadowing under an experienced supervisor.[S14]
GFT therefore integrates supervisory coaching directly into the daily cadence. During the first months of a greenfield factory, the production manager or an industrial engineer shadows a rotating sample of daily line huddles each week, observing whether the supervisor invites operator input on station constraints, separates controllable method adherence from external material or machine failures, and assigns clear follow-up checks.[S14][S1101] A shop-floor production planning and lean manufacturing case study published in Gestão & Produção in 2025 illustrates why operator and team-leader dialogue is essential: to identify the true reasons behind assembly-line stoppages, engineers combined written operator records on Overall Equipment Effectiveness (OEE) sheets with daily conversations with assembly-line team leaders.[S1102] In GFT's design, the daily huddle is the structured point where written station logs and frontline operational context meet.

Between daily huddles, the garment floor is governed through visual control. ILO guidance on lean manufacturing techniques for the ready-made garments industry states that the best approach to performance measurement is to balance metrics across financial, behavioural and core-process categories while using a mix of in-process and end-of-process indicators.[S02] On a sewing line, an end-of-shift summary is an end-of-process indicator: it tells management whether the shift succeeded after the labour hours have already been spent. Hour-by-hour visual control boards provide the in-process signal that lets a supervisor detect and correct a flow interruption within the hour it occurs.[S02][S1102]
Many factories install whiteboards or screens that display only a target piece count and an actual piece count, marking the cell in red whenever actual falls below target. That design violates three measurement principles established earlier in this paper. First, a raw piece count that includes defective or reworked garments overstates saleable throughput and hides the capacity consumed by repair loops; in a NIST MEP manufacturing case, improving first-pass yield from 10 percent to 90 percent was directly associated with cutting total processing time from 11.8 hours to 3.4 hours.[S10] Second, an uncontextualised shortfall does not distinguish whether the line slowed because of a machine breakdown, a missing trim batch or a method learning curve, which is the exact diagnostic failure identified in real-time OEE research when downtime events are merged into a single category.[S07] Third, a red numeral without an assigned responder and escalation status violates the basic rule of visual management, which is to make both the abnormality and the required response visible at a glance.[S22][S1102]
GFT specifies a six-block line board architecture, illustrated in Exhibit 51 using an illustrative eight-hour shift scenario for a 40-operator sewing line producing a woven workwear trouser at an approved SMV of 24.0 standard minutes per piece. Under a ramp-adjusted target efficiency of 65 percent during cohort week four, the illustrative shift target is 520 first-pass good pieces, or 65 pieces per hour across eight productive hours.[S03][S11]

As Exhibit 51 shows, a supervisor or manager standing at the board at the end of Hour 4 sees that first-pass good output is 32 illustrative pieces behind the cumulative target of 260 pieces because 14 units required rework, that 22 station-minutes were lost to a specific twin-needle feed-dog fault (DT-M04), that WIP has reached 38 illustrative pieces ahead of Operation 09, and that a certified utility operator has been assigned while the line mechanic has an owned corrective action due at 11:30 with verification scheduled at Hour 5.[S02][S04][S07] What Exhibit 51 cannot guarantee by itself is the accuracy of the underlying defect grading or downtime timestamps; those inputs depend on the measurement-system checks and source-capture rules defined in Chapters 4, 6 and 10.[S40]

In GFT's visual control design, an abnormality on the line board or station andon is coupled to a two-stage response rule: containment within the current hour, and escalation if the threshold is breached. In the Gestão & Produção lean visual-management study, physical magnets and colour-coded squares on the shop-floor board alerted workers and team leaders immediately when a batch required action or when a scheduling or capacity conflict required a designated decision-maker to intervene.[S1102] GFT applies the same principle to sewing and cutting flow:

Read this exhibit in its chapter ↗Daily huddles and hour-by-hour boards keep the current shift moving, but they are deliberately bounded to short-term containment and intra-line rebalancing. When a sewing line experiences four needle-bar or looper failures in a single week, when shade variation in dyed pocket fabric causes repeated cutting holds, or when two lines compete for the same three multi-skilled collar-attach operators, a 10-minute shift huddle cannot solve the underlying systemic constraint. Literature reviewing OEE implementations across manufacturing industries notes a widespread lack of improvement frameworks with systematic steps specifically developed to turn OEE loss measurement into sustained improvement.[S08] Monitoring an aggregate efficiency score without a structured weekly problem-solving forum leaves recurring losses embedded in the process.[S07][S08]
GFT establishes a weekly operational review, chaired by the plant manager or operations manager and attended by line supervisors, industrial engineering, quality assurance, maintenance, cutting/stores and human resources. Held for an illustrative 60 minutes on a fixed weekday morning, the weekly review does not re-read daily shift logs line by line. Instead, it examines seven-day and four-week rolling aggregations drawn from the authoritative record across all six KPI families: production, quality, delivery, cost, people and sustainability.[S02][S08]
The weekly review performs four analytical tasks that cannot be done inside a single shift:
Not every recurring problem discovered in the weekly review has a known solution. When the weekly Pareto reveals a persistent loss whose cause is uncertain or contested, such as a high seam-puckering rate on a lightweight shirting fabric across two shifts or an unexplained rise in compressed-air energy intensity per thousand standard minutes, the weekly review does not guess a countermeasure in the meeting room. Instead, it charters a formal Plan-Do-Check-Act (PDCA) or A3 investigation, assigns an engineering or quality owner, defines the baseline population, and schedules the investigation for review at defined milestones.[S05][S41] Chapter 12 specifies the diagnostic and verification mechanics of that improvement loop in full; the weekly management cadence provides the governance forum that commissions those investigations, allocates technician hours to them, and holds their owners accountable for follow-through.[S08][S41]

11.11 · the bodyExhibit 52 above; its figures are illustrative where marked.
While daily and weekly routines govern execution against the current schedule, a factory can still fail commercially and operationally if its order book is disconnected from its true floor capability. In a NIST MEP manufacturing case study, high finished-goods inventory, longer-than-desired lead times, decreased capacity and difficulty sustaining lean initiatives resulted directly in lower on-time deliveries, higher overtime costs and an excessive number of expedited orders.[S1103] In garment manufacturing, chronic expediting usually begins weeks before cutting, when commercial teams accept delivery dates based on theoretical machine counts while operations teams struggle with ramp-up learning curves, fabric arrival delays and unmeasured rework.[S10][S11][S42]
Sales and operations planning (S&OP) is the monthly discipline that prevents that disconnect. Academic research on S&OP implementation emphasises that S&OP is performed at least once a month and is reviewed by management at an aggregate product-family level, integrating customer-focused commercial plans with operations at the tactical level of the production planning hierarchy.[S42] Reviewing individual production tickets in a monthly executive meeting overwhelms leadership with thousands of stock-keeping units (SKUs); conversely, reviewing only a single plant-wide piece total conceals the fact that a basic T-shirt taking 7.0 illustrative standard minutes and a tailored jacket taking 45.0 illustrative standard minutes impose completely different work content and skill demands on the sewing floor.[S03][S42]
GFT structures monthly S&OP around product families defined by shared sewing routing, machine types and SMV bands (for example: basic knit tops, woven school and corporate uniforms, and heavy cotton workwear trousers). Each month follows a structured four-step reconciliation sequence over a rolling three-to-twelve-month horizon:
In Cameroon, the strategic importance of disciplined monthly S&OP is reinforced by the broader industrial context recorded in the shared evidence register. Sector sources indicate that roughly 95 percent of Cameroon's cotton fibre is exported raw while about 5 percent is processed locally, against a national industrialisation target of 50 percent local processing by 2030 under the National Development Strategy (SND30).[R06][R07] At the same time, historical reporting on existing domestic capacity highlights the cost of weak operational utilisation: a July 2023 report on CICAM cited capacity utilisation of 33.7 percent at Garoua, 48.9 percent at CICAM 1 and 10.83 percent at CICAM 2, with underutilisation costing about CFAF 2 billion in 2020.[R12]
GFT treats these inherited sector figures strictly as external industrial context, never as an automatic demand forecast or guaranteed utilisation level for a greenfield plant.[R06][R12] A national policy target of 50 percent local processing does not place a single confirmed purchase order on a sewing line, and historic underutilisation at another enterprise demonstrates why a factory must align its commercial order book, fabric supply and line capability month by month.[R07][R12][S42] Monthly S&OP is the governance forum where a greenfield plant ensures that its commercial promises match its demonstrated floor capability, while companion papers in this library examine statistical demand forecasting (wp04) and raw-material and finished-goods inventory buffering (wp12) in detail.[S42]
The arithmetic from this worked example is visualised in Exhibit 52, which reconciles gross scheduled operator time to net deliverable standard minutes across the five loss deductions.
Exhibit 52 makes the commercial and operational conversation objective. Instead of Sales accusing Operations of holding back capacity or Operations accusing Sales of selling impossible lead times, both functions inspect the same four deduction bars and decide which constraint can be moved within the planning window.[S42][S44] What Exhibit 52 cannot establish is whether raw fabric and trims will arrive on time for the 47,583 illustrative garments in the net deliverable plan; material readiness must be checked in parallel against supplier confirmation timestamps and warehouse inspection logs before a cutting order is released.[S42]

A multi-tier review cadence works only when participants know which problems belong at their tier and when a problem must move upward. The United States Federal Data Strategy's Data Governance Playbook defines data governance as setting and enforcing priorities for managing and using data as a strategic asset, which requires explicit decision rights and accountable roles rather than informal consensus.[S22] At the same time, public-sector performance-management guidance from the United States Office of Personnel Management stresses that performance elements and standards must be measurable, understandable, verifiable, equitable and achievable.[S45] Holding a sewing supervisor accountable for a missed daily output target when the cutting room delivered mis-numbered bundles or the main air compressor failed violates the achievability and equity standard.[S45]
In the Gestão & Produção lean shop-floor case study, designing the visual management system required explicitly defining not only what visuals would be implemented, but also who decides what to produce when there are scheduling or capacity conflicts.[S1102] GFT formalises that principle across all four tiers of the factory management cadence in Exhibit 53. Each forum is defined by its frequency, chair, governed inputs, permitted decisions, mandatory escalation triggers and verification rule.

Exhibit 53 eliminates ambiguity about where a decision lives. A line supervisor at Tier 1 has full authority to move a certified utility operator to Operation 09 or hold a defective bundle for inline repair, but cannot promise a customer a revised shipment date or authorise cross-line overtime.[S04][S45] Conversely, the general manager at Tier 4 commits the product-family order book and staffing plan, but does not override a quality inspector's defect classification on the sewing floor.[S22][S42] Note that the numeric time thresholds in Exhibit 53 (such as 10 to 12 minutes for a huddle or 20 minutes for a stop escalation) are illustrative GFT operating design parameters rather than universal constants; a plant must calibrate them to its physical layout and product mix.
Escalation is not solely a mechanism for reporting shop-floor failures upward; it is equally a mechanism for frontline teams to challenge flawed assumptions imposed from above. A 2025 review of Balanced Scorecard implementation in Encyclopedia notes a fundamental criticism of rational, top-down strategy execution: it frequently fails to align with decentralised or adaptive organisational realities.[S46] In a greenfield garment factory, top-down distortion occurs whenever an initial SMV calculation omits a fabric-handling difficulty, whenever a marker-efficiency target forces cutting operators to include selvage flaws, or whenever an aggressive ramp target pressures operators into unsafe speed.[S03][S17][S46]
To prevent top-down distortion, GFT embeds a formal standard-challenge trigger into the escalation path. If a qualified operator following the specified method cannot achieve the provisional standard time, or if an inline inspector finds that a construction specification causes needle-hole damage on a specific fabric batch, the line supervisor logs a Method or Standard Exception at Tier 1 and escalates it to Industrial Engineering and Quality Assurance at Tier 2 and Tier 3.[S03][S45] While that exception is under engineering review, the affected variance is coded to Method/Standard Under Review rather than operator performance loss, protecting workers from inequitable evaluation and ensuring that the data dictionary reflects physical reality.[S22][S45]
The complete path from an observed variance at the station to a verified decision across the operational and commercial tiers is depicted in Exhibit 54.

As Exhibit 54 illustrates, no escalation branch terminates merely because a manager has been informed or an instruction has been issued. Whether an exception is contained at Tier 1 through a station rebalance, resolved at Tier 2 by replacing a worn feed dog and updating the preventive maintenance checklist, or reconciled at Tier 4 by re-phasing a customer delivery schedule, the decision is written into the governed action log (Node 5), waits for the defined observation window to elapse, and is tested against the authoritative KPI record (Node 6) before closure (Node 7).[S22][S43] A process flow diagram like Exhibit 54 is an architectural design contract rather than empirical proof of compliance; whether the plant actually follows these edges without bypassing the verification step must be audited through the action log itself.

The most common failure in factory performance management is meeting amnesia: a problem is discussed earnestly in Tuesday's review, an informal verbal instruction is given, and by the following Tuesday either the instruction has been forgotten under the pressure of new urgent orders, or the task was performed mechanically without checking whether the problem actually disappeared.[S08][S41] The UK Department for Transport's Benefits Management and Evaluation Framework highlights a governance principle that applies directly to operational improvement: a management framework must ensure that expected benefits are actively owned, managed and monitored beyond the point of project or task completion.[S43] Similarly, Lean Enterprise Institute guidance on testing A3 problem solving stresses that reading an A3 backwards from follow-up to countermeasure, root cause and target condition allows owners and leaders to confirm a logical, fact-based thinking process.[S41]
To serve as the factory's institutional memory between daily, weekly and monthly forums, GFT treats the Action Log as a governed entity inside the system of record defined in Chapter 10.[S22] An item cannot be entered into the action log as a vague aspiration such as "improve sewing quality on Line 2" or "reduce mechanic downtime".

ACT-2026-0142), date opened, and the forum tier (Tier 1, Tier 2, Tier 3 or Tier 4) that commissioned it.[S22]Task completion is not action closure
A persistent governance failure in manufacturing review systems is allowing action owners to mark an item closed on the day a mechanic replaces a part, an engineer issues a revised work instruction, or a supervisor holds a briefing.[S08][S43] In GFT's cadence rules, executing the task moves the action status only from Open to Implemented: Awaiting Verification. The action remains on the weekly review dashboard until the verification window closes and the governed operational record demonstrates that the target KPI moved in the expected direction while guardrail indicators remained intact.[S02][S43] If a mechanic replaces a looper on Tuesday (Implemented), but the Thursday and Friday shift logs still show 18 illustrative minutes per shift of thread-break downtime on the same machine, the action automatically reverts to Re-opened: Hypothesis Refuted at the next review. Only verified operational improvement closes an action.[S41][S43]

Read this exhibit in chapter 14 ↗Because meetings consume supervisory and engineering hours, the management cadence must evaluate its own effectiveness with the same rigour it applies to sewing lines. In their evaluation model for sales and operations planning maturity published in Production, Grimson and Pyke's five-stage evolutionary framework is analysed across five distinct categories: meetings and collaboration, organisational structure, measures of performance, information technology and integrated planning.[S44] That research underscores two critical findings for a greenfield factory. First, maturity is multi-dimensional: a company can have advanced information-technology tools while remaining in a low-maturity zone on processes, meetings and collaboration.[S44] Second, gaining maturity is not automatically achieved by how many times a process cycle has been repeated on the calendar; it depends on deliberate effort and the willingness of participants to make the cross-functional process work.[S44]
To prevent daily huddles, weekly loss reviews and monthly S&OP from decaying into hollow rituals, GFT audits the cadence itself once a month (and comprehensively at the quarterly governance review) using five operational indicators derived directly from the action log and meeting attendance records:[S22][S44]
No Action Required: Within Control Band disposition) within the scheduled meeting duration.[S44][S1102] A 10-minute huddle that runs for 28 illustrative minutes is a symptom of poor visual control preparation.Verified & Closed actions whose specific defect code or downtime cause re-emerges above threshold on the same line within an illustrative 30-day window, indicating that standardisation or preventive maintenance failed to hold.[S08][S43]By installing a fixed daily, weekly and monthly cadence from the first quarter of operation, a greenfield garment factory closes the loop between the data spine of Chapter 10 and the physical sewing line. Every measure in the six-family scorecard has a home: hourly and shift flow indicators live on the line board and in the daily huddle, multi-line loss patterns and working-time guardrails live in the weekly plant review, and aggregate demand-to-capacity trade-offs live in monthly product-family S&OP.[S02][S04][S42] Crucially, when the weekly review or the action-log audit reveals that a recurring defect or availability loss does not yield to routine supervisory containment, the cadence does not leave the floor to guess. It hands a clearly bounded, dated problem statement to the factory's formal corrective-action and standardisation loop, which is the subject of Chapter 12.[S05][S41]

The paper's rack · 14 boltsBolt length: reading time
01Part I: The measurement contract
A factory without an operating baseline cannot rely on hindsight, so GFT treats measurement as part of production from the outset.
02Part I: The measurement contract
Early targets should describe a controlled learning trajectory, with yield, rate and capability observed together rather than assumed away.
03Part I: The measurement contract
Strategic intent becomes an operating system when each line measure carries a decision, an owner, a feasible record and a guardrail.
04Part I: The measurement contract
Operational definitions, data-quality controls and measurement-system analysis must precede target comparisons and automated analytics.
05Part II: Measure the operating system
Good output is the result, while the production system must retain the component losses that explain why the result occurred.
06Part II: Measure the operating system
The quality system should connect first-pass yield, defect causes and variation so that inspection leads to prevention rather than sorting alone.
07Part II: Measure the operating system
Standard work, balanced capacity and order-level flow records must support the delivery promise before expediting becomes routine.
08Part II: Measure the operating system
A low nominal wage does not establish a low cost per good garment, so the people scorecard must include skill, supervision, attendance and working-time effects.
09Part II: Measure the operating system
Energy, water, waste and emissions become manageable only when each quantity has a declared boundary, source record and production denominator.
10Part III: Turn records into decisions
Source capture, master data and explicit stewardship turn daily logs into an operational asset without requiring a heavy platform on day one.
11Part III: Turn records into decisions
Daily correction, weekly problem solving and monthly reconciliation give each signal a forum, an authority level and a recorded response.
12Part III: Turn records into decisions
A corrective-action system should distinguish abnormal variation, test causes, verify effects and update standard work rather than count completed actions.
13Part IV: Scale with control
The factory should earn each digital step through reliable records, active management and verified improvement rather than buy a platform to compensate for their absence.
14Part IV: Scale with control
GFT recommends four gated stages: clean capture, active cadence, verified improvement and a data-driven floor, with value measured in the same system throughout.
