Key takeaways

  • The 21 industrial performance indicators are divided into 7 families: HR, productivity, quality, costs, maintenance, supply chain and finance.
  • TRS (Taux de Rendement Synthétique - Synthetic Efficiency Rate) remains the benchmark indicator in the factory: it combines availability, performance and quality in a single figure.
  • Don't try to measure everything. The golden rule: 5 to 10 KPIs maximum per hierarchical level, chosen using the SMART method.
  • An indicator is only as good as its understanding and use by field teams - visual displays, daily updates and analysis rituals make all the difference.
  • Structured skills management has a direct impact on the majority of these KPIs: absenteeism, productivity, scrap rates, cycle times.

An industrial performance indicator measures the gap between what a facility was supposed to produce and what it actually produced, in terms of volume, quality, lead time, or cost. The 21 indicators selected here are divided into seven categories, ranging from equipment to team skills.

Each one is described along with its formula, a numerical reference, and its main pitfall when interpreting the data. The references come from public sources (AFNOR, Assurance Maladie, Ipsos bva) and a study conducted using data from the Mercateam platform.

This study covers 210 industrial sites monitored from August 2025 to August 2026. It quantifies a rarely measured aspect of production dashboards: the ability of teams to perform their duties according to established procedures.

How do you interpret the study's metrics?

Each rate is calculated on a site-by-site basis and then summarized by sector. The median corresponds to the middle site, with half of the sites performing better. The first quartile (P25) and the third quartile (P75) enclose the middle half of the sites.

What is an industrial performance indicator?

An industrial performance indicator, or KPI (key performance indicator), is a numerical metric calculated at regular intervals that compares a production outcome to a target. It involves a fixed formula, a target, and a person responsible for it.

There are two types of indicators. Outcome indicators reflect a fact that has already occurred, such as the weekly OEE or the monthly scrap rate. Capacity indicators measure the factors that influence these outcomes, thereby providing time to take action before a deviation occurs.

A balanced scorecard combines both. The 21 selected indicators start with equipment and work their way up to the teams, and five additional, more financial indicators round out the list.

What metrics should be tracked for equipment?

Four indicators describe the production equipment. OEE and TRG measure its efficiency, MTBF measures its reliability, and MTTR measures the time to resume operation after a failure.

1. Total Return (TRS)

What it measures
The efficiency of a piece of equipment over the time it was supposed to be in production. Known as OEE in English, it is standardized in France by NF E60-182 (AFNOR, 2002).
Formula
TRS = availability rate × performance rate × quality rate
Landmark
85 % corresponds to the "world-class" standard set by Seiichi Nakajima, the founder of TPM. Most discrete manufacturing sites operate closer to 60 % (OEE.com).

Equipment with a capacity of 90 %, operating at 85 %, and producing 95 % of good parts has an OEE of 72.7 %. The aggregate figure does not indicate where time is lost; it is its three components that pinpoint this.

Performance depends directly on the operator: settings, micro-stops, and maintaining a steady pace. If performance drops only during certain shifts, find out who was working those shifts before opening a machine trace.

Quality & TRS

Boost your TRS with qualified operators in the right place

The majority of quality and output discrepancies are due to poorly staffed positions. Visualize the real skills of each operator and assign the right people to the right jobs.

2. Internal Rate of Return (IRR)

What it measures
Productivity relative to total operating time, including scheduled downtime: breaks, scheduled maintenance, and periods with no orders.
Formula
TRG = effective time / opening time
Landmark
It is always less than or equal to the TRS, since its denominator is broader.

The gap between TRS and TRG highlights work stoppages initiated by management. If this gap widens without a reduction in workload, the site is leaving capacity unused—for example, due to a lack of qualified operators to start an additional shift.

3. MTBF (Mean Time Between Failures)

What it measures
The average length of time a piece of equipment operates without failure (mean time between failures).
Formula
MTBF = total operating time / number of failures
Landmark
Track performance on a machine-by-machine basis and by trend, never based on the fleet average.

A declining MTBF indicates aging equipment, insufficient preventive maintenance, or changes in operating conditions. When tracked on a machine-by-machine basis, it helps prioritize investments in replacement or refurbishment.

4. MTTR (Mean Time to Repair)

What it measures
The average time required to get equipment back up and running after a failure (mean time to repair).
Formula
MTTR = total downtime for repairs / number of failures
Landmark
Analyze the distribution of durations: just a few very long procedures are enough to skew the average.

The typical causes of a high MTTR are well known: missing parts, lengthy diagnostics, and technicians who are not sufficiently trained on the equipment. Another cause is less obvious when looking at the average: the availability of the only person authorized to perform the repair.

What the data show

Of 108 sites organized by sector, 105 have at least one qualification or certification held by a single active employee. In the aerospace sector, the median is 52 such exclusive holdings per site, including a median of 7 certifications.

When a task requires one of these authorizations and the authorized person is absent, the repair must wait until that person returns. Count the number of authorized technicians for each critical task: if there is only one, the MTTR for that task depends on the vacation schedule.

When considered alongside the MTBF, it provides a complete picture of the fleet's reliability: one metric indicates how frequently failures occur, while the other shows how long they halt production.

Maintenance & reliability

Reduce your MTTR with authorized technicians and available

Keep track of your maintenance teams' authorizations in real time, anticipate renewals and assign the right profiles to the right jobs to limit line stoppages.

Productivity and Throughput Metrics

Labor productivity is the ratio of output to hours worked. Cycle time indicates whether this output is being produced at the rate required by demand, as expressed by takt time.

5. Labor Productivity

What it measures
The volume produced per hour worked or per operator.
Formula
Productivity = quantity produced / number of hours worked
Landmark
Comparison from one period to the next, assuming a constant product mix and scope.

A decline is often interpreted as a shortage of staff. First, check whether the current staff can handle the most demanding positions: a site may be fully staffed in terms of numbers but understaffed in its most demanding positions.

What the data show

Depending on the sector, the median number of positions held by fewer than three fully qualified operators ranges from 24.8 % in the pharmaceutical industry to 77.8 % in the automotive industry (see KPI 17 for details).

Next, cross-reference productivity with absenteeism and the staffing schedule to identify the root cause: bottlenecks, lack of training, or chronic understaffing.

6. Cycle time and takt time

What it measures
The actual production time for a unit, as compared to the takt time—the pace dictated by customer demand.
Formula
Cycle time = end of production – start of production; takt time = available production time / customer demand
Landmark
Cycle time less than or equal to the takt time.

With a takt time of 60 seconds, one part must come off the line every minute. A longer cycle time means that the production rate cannot be maintained without overtime or additional staff, while a much shorter cycle time risks creating excess inventory.

When cycle time deteriorates at a workstation for reasons unrelated to the machine, examine the operator’s recent practices. A skill that has been certified but not practiced remains recorded in the matrix, even though the operator may have lost the ability to perform the task.

What the data show

We compared the skills validated at the operational level with the scheduled hours over a 12-month period, excluding cross-functional skills and considering only employees who all worked during that period.

The median number of skills never assigned is 26.1 % in the pharmaceutical industry, 32.4 % in the cosmetics industry, 40.8 % in the agri-food industry, 44.9 % in the automotive industry, and 49.6 % in the aerospace industry.

Three Metrics for Quality Management

The scrap rate includes what ends up in the dumpster, the first-pass yield (RPP) includes what isn't good on the first try, and the cost of nonconformity converts both into euros.

7. Reject rate

What it measures
The portion of production that fails inspection and cannot be salvaged.
Formula
Scrap rate = (quantity scrapped / total quantity produced) × 100
Landmark
Track by position and by team, not just by line.

An increase can be attributed to three factors: setup, materials, and skill. The first two are documented in most MES systems; the third depends on whether the operator met all the job requirements at the time the batch was produced.

What the data show

Of the 4,511 positions analyzed across 98 sites, 1,538 have no operator who meets 100 % of their requirements, representing 34.1 %.

SectorPositions AnalyzedNo full-time playerPart
Automotive1 15664756,0 %
Cosmetics2558834,5 %
Food industry61119531,9 %
Aeronautics2 11253325,2 %
Pharmaceuticals3777519,9 %
Together4 5111 53834,1 %

Positions with at least one required skill or authorization configured, August 2025 through August 2026.

A position without a fully qualified incumbent has no employee who possesses all of its required skills and authorizations. Either the requirement is genuinely missing from the team, or the matrix has not been filled out: in either case, no compliant assignment is possible.

Compare this list with your rejects by station. If the quality issues are concentrated there, focus on skills first, before adjusting settings or changing materials.

8. First-Pass Yield (FPY)

What it measures
The percentage of parts that meet specifications on the first pass, without rework (first-pass yield, FPY).
Formula
RPP = (first-pass conforming parts / parts produced) × 100
Landmark
Always less than or equal to 100: % minus the scrap rate.

More stringent than the scrap rate, the RPP also includes successfully reworked parts. The difference between the two measures the amount of rework that the shop absorbs without it being counted as scrap.

9. Cost of Non-Quality

What it measures
All expenses resulting from defects, both internal (scrap, rework) and external (returns, product recalls, claims, penalties, damage to reputation).
Formula
Cost of non-quality = scrap + rework + returns + claims and penalties
Landmark
Expressed in euros and as a percentage of revenue.

Internal costs are calculated based on production data. External costs require data from customer service and accounting, which is why they are often omitted from the calculation.

In euros, this cost can be directly compared to a training or maintenance budget, which is not possible when using a percentage.

How can you track production costs and deadlines?

The unit cost indicates how much a part costs, the lead time indicates how long the customer has to wait, and the OTD indicates whether the promised delivery date was met.

10. Production cost per unit

What it measures
The total amount spent to manufacture one unit: materials, labor, energy, and depreciation.
Formula
Unit cost = total production costs / units produced
Landmark
Analyze on a constant-volume basis, cost center by cost center.

Increasing production rates lowers the unit cost without any real improvement, simply by spreading out fixed costs. Also track the labor cost per unit, which includes overtime and temporary replacement workers.

When tracked over time, it measures the actual impact of continuous improvement initiatives on material waste, downtime, poorly calibrated processes, and energy consumption.

11. Lead Time

What it measures
The total time from when an order is received until it is delivered to the customer.
Formula
Lead time = actual delivery date – order receipt date
Landmark
Broken down by stage: procurement, waiting, production, shipping.

When broken down, lead time generally shows that the waiting time between stages accounts for a larger portion than the production process itself. Reducing it without improving reliability in the upstream stages shifts the problem to quality.

12. Customer Service Rate (OTD)

What it measures
The percentage of orders delivered on time.
Formula
OTD = (orders delivered on time / total orders) × 100
Landmark
Threshold set by the client, often 95 % or higher: below this level, the client relationship becomes fragile.

As an output indicator, the OTD provides an overview of planning, production, quality control, and shipping. When it drops for no apparent reason in production, review the weeks when the assignment schedule was the most heavily edited (KPI 15).

HR Metrics That Drive Production

Absenteeism, turnover, and schedule stability measure whether the planned workforce is present and the cost of reorganizing it. These are the starting points for capacity indicators—the ones for which the study provides the most insights.

13. Absenteeism Rate

What it measures
The proportion of work time lost due to unplanned absences: illness, accident, or unexcused absence.
Formula
Absenteeism rate = (days absent / scheduled workdays) × 100
Landmark
4.98 % in 2025 across all sectors, compared with 4.84 % in 2024 (Social Performance Observatory 2026, Ipsos BVA for Oasys and Diot-Siaci).

A rate that consistently exceeds the national average should be cause for concern: it often indicates excessive workload, physically demanding conditions, or a lack of recognition. When tracked monthly, it highlights seasonal trends and the teams most affected.

An overall rate combines long absences—which are planned—with short absences discovered when an employee starts their shift. Track them separately, because it’s the short absences that require reassignment within the hour.

Two sites with 5 % in absenteeism do not pay the same price for it. The difference stems from their ability to replace employees with qualified personnel, as measured by versatility and position coverage (KPIs 16 and 17).

14. Turnover

What it measures
The rate of departures relative to the workforce.
Formula
Turnover = (departures during the period / average headcount) × 100
Landmark
Break down the data by tenure and status before drawing any conclusions.

Every departure comes at a cost in terms of recruitment, onboarding, job training, and lost expertise—not to mention the impact on the remaining teams. Exit interviews and performance reviews help us understand what motivates employees to leave.

When an employee leaves, the company loses the skills that person possessed. However, versatility builds up with seniority during the first few years and then levels off, with different trajectories depending on the contract.

Percentage of employees who hold at least two positions, by length of service and contract type

A position is considered mastered when the employee meets 100 % of the required competencies and authorizations.

Permanent ContractTemporary WorkFixed-Term Contract
Source: Mercateam study, active employees at the sites surveyed, August 2025 through August 2026. Employees on fixed-term contracts and temporary workers with more than ten years of service are rare; their percentage should be interpreted with caution.

For permanent employees, the percentage rises from 10.6 % in the first year to 23.5 % between one and three years, then to 31.8 % between three and ten years. After ten years, it increases by only one point.

An employee who has been on a permanent contract for more than three years is therefore three times more likely to hold two positions than a new hire. Turnover concentrated among this group has a greater impact on flexibility than a higher turnover rate among new hires.

The percentage of temporary workers who have been on the job for three to ten years stands at 43.4 %, higher than that of permanent employees. A likely explanation: since they are assigned to areas where there is a shortage of staff, they change jobs more often.

15. Schedule Stability

What it measures
The percentage of allocations carried out as published.
Formula
Stability = (assignments unchanged between publication and execution / total assignments) × 100
Landmark
To be updated weekly, with the date and time of the changes.

A schedule that is constantly being revised reflects unforeseen circumstances (absences, breakdowns, emergencies) or a plan that was drawn up without knowing who can fill which position.

The time period during which the changes are concentrated helps distinguish between the two. This is the first piece of data to look at when trying to improve the staff scheduling management.

Wednesday and Thursday account for 45 % of the most recent updates, with a peak on Wednesday at 8 a.m. On weekdays, 48 % of these updates occur between 6 a.m. and 12 p.m., when employees start their shifts.

The schedule therefore stabilizes during the current week rather than before it begins. Friday accounts for only 14.7 % of the volume, and the weekend accounts for less than 4 %.

Measurement limit. Successive versions of a schedule are not tracked, so the analysis does not calculate the stability rate itself. Instead, it tracks the number and timing of the most recent updates, including new creations.

For sites of comparable size, the volume varies from one-third to three or even four times as much between the first and third quartiles. This discrepancy reflects a combination of differences between sites and week-to-week variations.

What metrics should be used to manage production capabilities?

A position is considered to be properly staffed when the operator meets all its requirements: validated skills and valid certifications. Depending on the sector, a position has an average of 3.73 (pharmaceutical) to 7.20 (automotive) such requirements.

The following three indicators are based on this strict definition. An operator who meets six out of seven requirements may work at the position every day, but is not counted as qualified.

16. Versatility Rate

What it measures
The percentage of operators capable of filling at least two positions while meeting 100 % of their requirements.
Formula
Versatility rate = (operators proficient in at least 2 positions / total number of operators) × 100
Landmark

The industry classification is less important than the width of the bars. In the automotive sector, the top quartile of sites peaks at 0.8 %, while the bottom quartile reaches 67.4 %, under the same business constraints: site organization has a greater impact than the industry on the versatility.

Nor does the number of requirements explain the rate. The pharmaceutical industry (3.73 requirements per position) and the automotive industry (7.20) have nearly identical medians: 14.6 % and 14.9 %.

The rate also fluctuates from year to year—and not always for the better—because an expired authorization removes coverage from a position even when the procedure remains under control.

Source: Mercateam study. Up or down: a change of more than 2 points between the first four and the last four weekly readings for the period.

In each sector, between one in five and one in three sites saw their versatility decline over the course of a year. A survey limited to the’annual personal interview does not allow us to see these setbacks taking shape.

What level of versatility should you aim for?

Instead of using the median for your industry, use the third quartile as a benchmark: between 32.6 % and 36.6 % depending on the industry, and 67.4 % in the automotive industry. Start with positions held by fewer than three people.

17. Position Coverage Rate

What it measures
The percentage of positions held by at least three fully qualified operators.
Formula
Coverage rate = (positions with at least 3 qualified incumbents / total positions) × 100
Landmark
Median number of understaffed positions (with fewer than 3 employees) ranges from 24.8 in the pharmaceutical sector (Q1–Q3) to 77.8 in the automotive sector (Q1–Q3). Mercateam study

The three-staff member threshold is a standard rule for using cross-functional rosters: it allows for the simultaneous coverage of an absence and a time-off without assigning the task to an unqualified person.

Source: Mercateam study, 98 sector-based sites, August 2025 through August 2026. Each dot represents a sector.

The five sectors are arranged in the same way along both axes. Five points are not enough to establish a pattern, but the mechanism is arithmetic: each additional requirement reduces the number of people who meet all of them.

Be sure to measure coverage before and after any changes to the reference framework. Adding an authorization to a position may be justified, and the resulting loss of flexibility can be quantified at the same time.

There remains significant variation from one site to another: in the automotive sector, the first quartile has 33.3 % understaffed positions, while the third quartile has 100 %. Before providing training, check for validated skills that have never been assigned (KPI 6), which is the primary source for filling vacancies.

18. Rate of exclusive jurisdiction

What it measures
The number of certifications or authorizations held by a single active employee at the site.
Formula
Monopolies = exclusive authority and powers granted to a single entity; as a percentage of positions = (positions with a single incumbent / total positions under control) × 100
Landmark
97 % of the sectorized sites have at least one monopoly. Mercateam study

Food industry18100 %57,1 %

Source: Mercateam study. Positions with a single incumbent were calculated based on sites with at least one position under control, ranging from 9 to 28 sites per sector.

The two measures do not overlap. In the field of cosmetics, the median number of positions with a single incumbent is zero, whereas the sites have a median of 9 competencies or authorizations with a single holder.

A dual role may therefore conceal specific expertise possessed by only one person, and only the second person can bring that expertise to light.

The aviation figure also reflects the sophistication of the standards: the more a site details its specialized processes and individual certifications, the more rare skills it identifies. In this sector, you should primarily compare yourself to your own track record.

In the automotive sector, the average number of positions with a single incumbent (24.8 %) is three times the median (8.3 %), and the third quartile stands at 50 %. A few highly exposed sites are driving the average upward.

These critical skills are the first to be included in the training plan—before the announced departures, rather than after.

Security and Compliance Metrics

The frequency rate tracks reported accidents. The compliance rate and the up-to-date matrix rate verify in advance that individuals in each position possess the required qualifications and that this information is reliable.

19. Workplace Accident Frequency Rate

What it measures
The number of work-related accidents resulting in lost time, relative to the number of hours worked.
Formula
TF = (lost-time accidents × 1,000,000) / hours worked
Landmark
Nationally, the frequency rate stood at 26.4 lost-time accidents per 1,000 employees in 2024, compared with 26.8 in 2023 (2024 Annual Report of the Health Insurance Program: Occupational Risks).

Beyond the human aspect, every accident disrupts service, triggers an investigation, and requires teams to be reorganized.

Do not confuse these two metrics. The frequency rate relates accidents to hours worked, while the Health Insurance frequency index relates accidents to the number of employees: only the former provides a fair comparison between sites with different work schedules.

The TF remains a performance indicator that changes once an accident has occurred. Supplement it by tracking near-misses and using a leading indicator: assignment compliance.

20. Compliance Rate

What it measures
The percentage of scheduled assignments in which the employee possesses all the skills and authorizations required for the position.
Formula
Compliance Rate = (Compliant Assignments / Total Assignments) × 100
Landmark

Over a 12-month period, 523,745 of the 3,651,583 assignments analyzed involved an employee who was missing at least one requirement, or approximately 1,435 per day. Per site, the median is 14.2 %, with the first quartile at 3.6 % and the third quartile at 31.2 %.

The rate rose from 11.25 % in August 2025 to 16.4 % in July 2026. This increase could reflect a genuine deterioration, such as expanded reference sets or sites currently being configured; however, the aggregated data does not allow for a definitive conclusion.

A non-compliant assignment does not necessarily pose a security risk: the missing requirement could be a quality competency or an authorization that has expired. Break down the rate by type of requirement before presenting it to the committee.

21. Current Matrix Rates

What it measures
The percentage of workers for whom at least one skill has been assessed or updated within the last 12 months.
Formula

The frequency of updates is also measured in days. The median time between updates to an employee’s record is 49 days, and it exceeds 118 days for one-quarter of employees.

Five complementary indicators, ranging from maintenance to finance

These five indicators are not included in the main list because they are typically reviewed by the executive committee or during the annual review. However, they do complement the performance dashboard for an industrial site.

Additional Indicators at a Glance

Employee Satisfaction Index

Measured through quarterly or semiannual surveys, it assesses the well-being and engagement of teams. Satisfied employees are more engaged and take fewer days off—provided that companies address the issues raised rather than simply collecting feedback.

Fairness in work assignments is a key factor in this score. When only three operators are able to handle a demanding position, it is always the same ones who are assigned to it—a situation that can be anticipated based on position coverage and monopolies (KPIs 17 and 18).

Preventive Maintenance Ratio

The goal is to increase the proportion of preventive maintenance rather than to reduce spending, with an 80/20 split often targeted. Every euro spent on preventive maintenance prevents emergency repairs, production line downtime, and production losses.

A stagnant ratio may be hampered by the availability of technicians authorized to perform preventive maintenance: as soon as a breakdown occurs, they are dispatched to handle the corrective work, and the preventive maintenance round is skipped.

Inventory Turnover Rate

A high inventory turnover rate means that inventory is moving and being converted into revenue. A low turnover rate ties up capital and increases the risk of obsolescence. The optimal level depends on the industry and lead times.

Gross Profit Margin

As a financial barometer for the factory, the gross margin measures the profitability of production before indirect expenses. If it declines while volume remains stable, either costs are rising or selling prices are eroding.

Track it month by month and product by product: a consolidated figure at the site level masks the unprofitable items among the profitable ones.

ROI of Industrial Equipment

Calculated before the purchase, the projected ROI helps the investment committee prioritize projects. Calculated after implementation, the actual ROI confirms or refutes the initial assumptions.

The difference between the two is also due to the teams: a new production line, whose settings few operators are familiar with, takes longer to reach its rated output. Include the training plan in your calculations from the start.

How do you choose the metrics for your dashboard?

Select 5 to 10 metrics per management level, based on your 3 to 5 priority issues. A team leader doesn’t need the same KPIs as a manufacturing director, and a 21-row table simply won’t be read through.

Each selected indicator must be SMART: specific, measurable, achievable, relevant to decision-making, and tracked over a defined period. Then, associate each outcome indicator with a capacity indicator that anticipates it.

A metric is only useful if it is understood by the field teams. When displayed at workstations, updated daily, and discussed during team meetings, it becomes a management tool; when displayed in an office that no one visits, it makes no difference.

Before each review, also ask when the data used to calculate the indicator was collected. A rate calculated based on evaluations from more than a year ago reflects the site's history more than its current operations.

Environmental indicators (energy or carbon per unit produced, water consumption, waste recovery) now complement these dashboards, driven by regulations and the requirements of contracting authorities.

Benchmarks for KPIs 15 through 18, 20, and 21: Mercateam study. Other benchmarks: AFNOR, OEE.com, Ipsos BVA, Assurance Maladie. The lines marked «+» include additional indicators.

Most of these metrics are calculated using data from your ERP, MES, CMMS, or HRIS. Skills are an exception: although they are often spread across multiple files, they are used to calculate five of these metrics (KPIs 16 through 18, 20, and 21).

To see where your site fits into the study's framework based on your own data, request a Mercateam demo.

About the study. The figures labeled «Mercateam study» are derived from the anonymized and aggregated analysis of data from 210 industrial sites equipped with the platform—representing 59,298 active employees—over a 12-month rolling period (August 2025 to August 2026).

Demo accounts and internal environments are excluded. A position is considered mastered when the employee meets 100 % of its configured requirements, validated skills, and valid authorizations.

Each rate is calculated on a site-by-site basis and then summarized by sector using the median and quartiles. The sample size varies depending on the indicator: 98 to 108 sites grouped by sector for skills, 104 sites for scheduling, and 23,269 employees for skills development.

Mercateam serves more than 300 industrial sites; the study included the 210 sites whose data met its inclusion criteria.

These data describe the manufacturers that use Mercateam and are not intended to represent the industry as a whole.

How can KPIs be used to improve industrial performance?

By continuously monitoring indicators, identifying deviations, then implementing corrective actions such as training, preventive maintenance, automation or better schedule management.

What are the most important industrial performance indicators?

There is no universal list. If quality is your challenge, then OEE and scrap rate are a must. If it's productivity, focus on labor productivity and cycle time. In general, OEE is considered to be the benchmark indicator, as it summarizes availability, performance and quality in a single figure.

What's the difference between TRS and TRG?

The SRR (Synthetic Efficiency Rate) is calculated on the basis of the time required, i.e. the time when the machine is supposed to be producing. The OEE (Overall Efficiency Rate) takes into account the total time the site is open, including periods of voluntary non-production. The OEE is always less than or equal to the OER. It gives a broader view of your asset utilization.

How many indicators should be tracked in a production dashboard?

The golden rule: between 5 and 10 indicators maximum per hierarchical level. An operator doesn't need the same KPIs as an industrial manager. Multiply the indicators and you end up with a dashboard that nobody consults. Select those which directly inform your decisions and which your teams can influence.

How do you set up KPI tracking in the factory?

The process is structured in three stages. First, define the objectives: what are you trying to improve? Next, choose the appropriate indicators (SMART method) and define the monitoring frequency. Finally, make the data accessible: visual display in the field, daily updates and team rituals to analyze discrepancies. A digital tool such as a skills matrix coupled with an assignment schedule facilitates this monitoring by centralizing data.

What's the link between skills management and industrial performance?

Multi-skilling and upskilling operators have a direct impact on most of the indicators presented here: absenteeism, productivity, scrap rates, cycle times. A trained, multi-skilled operator can be reassigned quickly in the event of absence, maintain quality on several shifts and reduce downtime. At Mercateam, sites that digitize skills management find that up to one day a week is saved on scheduling, and training time is divided by 4.
