capacity utilization

Activity-to-capacity relationship

Record the operational definition, its adopting source or organization, and the question it is intended to answer.

1. Does utilization mean output relative to output capacity, productive time relative to available time, or occupancy relative to availability? definition
2. Which organization or methodology supplies this definition, and how does it differ from other definitions used for this system? provenance

Included resources and work

Record the resources, production stages, and work categories covered by the observation.

1. Does this value describe a machine, a work center, an entire process, a facility, or an aggregate of producers? boundary
2. Are outsourced production, shared resources, setup, and rework included consistently in both activity and capacity? boundary

Reference capacity convention

Record the benchmark definition, estimation method, and allowances that shape the denominator.

1. Is the denominator nameplate capacity, sustainable output, effective capacity, or capacity available under a specified schedule? definition
2. How was reference capacity established, and which maintenance, downtime, staffing, and shift allowances were applied? provenance

Capacity validity conditions

Record the conditions under which the denominator applies and changes that require its revision.

1. For which product mix, staffing level, input conditions, and operating restrictions is this capacity estimate valid? boundary
2. Did additions, retirements, maintenance outages, or changed shifts alter capacity during the interval, and how were those changes incorporated? measurement

Counted production or time

Record the activity evidence, counting rules, and conversions used in the numerator.

1. Does the numerator count gross output, acceptable output, productive hours, or occupied hours, and how does it treat rejects and rework? measurement
2. Which production records, meters, time logs, or survey responses support the activity value? provenance

Compatible and interpretable ratio

Record the formula, unit alignment, interval alignment, and handling of invalid or exceptional denominators.

1. Do numerator and denominator use the same output equivalents or time units and cover the same reference interval? measurement
2. If capacity is zero or unknown, or utilization exceeds 100%, should the result be withheld, qualified, or investigated for benchmark mismatch? action

Comparison basis

Record which observations are comparable and which adjustments or qualifications are required.

1. Do the compared observations use equivalent capacity definitions, product-mix assumptions, shift calendars, and output measures? boundary
2. How much of the observed change comes from activity, capacity revisions, seasonal adjustment, or a change in reporting method? measurement

Weighting and hidden variation

Record aggregation weights, population coverage, and variation concealed by a single aggregate value.

1. Is aggregate utilization calculated from compatible summed quantities or from weighted individual rates, and what justifies the weights? measurement
2. Which overloaded resources, idle facilities, or excluded producers are hidden by the aggregate? boundary

Recoverable spare capacity

Record whether the gap to reference capacity is accessible and what prevents its use.

1. Can apparent spare capacity produce the required product or service with available labor, inputs, tooling, and downstream capacity? boundary
2. What evidence distinguishes low demand from downtime, input shortages, scheduling losses, or a bottleneck elsewhere? provenance

Utilization-informed intervention

Record proposed actions, their operating assumptions, and performance measures needed to evaluate them.

1. Given demand variability, queues, maintenance needs, and service commitments, what evidence supports the proposed utilization target? action
2. Would rescheduling, maintenance, an added shift, demand management, or additional capacity address the diagnosed constraint, and how would the outcome be evaluated? action
