Workforce KPIs for manufacturing are the few numbers a site manager can work out each week or month from the roster and payroll. They show whether the crew has the capacity, reliability, stability and skills the line needs. This guide gives eleven measures, each with a formula and the decision it supports. It is written for site, production and operations managers.
Pick measures you can pull from the roster and payroll this week
A useful measure comes from data you already hold: the roster, timesheets, payroll, the leavers list and training records. If a number needs a new system before you can read it, leave it off for now.
Group the measures by the question they answer. Capacity asks whether you have the hours. Reliability asks whether people turn up and shifts get covered. Stability asks whether people stay. Capability asks whether the crew can run every station safely.
Hiring measures such as time to hire and cost per hire sit on a different dashboard. The post on recruitment analytics in warehousing covers them, and the post on what to expect from a talent acquisition partner lists the measures to hold a partner to. For the maintenance crew, the post on building a maintenance team has a section on department KPIs. The one-off record of a seasonal engagement is a separate job, covered in the article on seasonal staffing review numbers.
Capacity measures: hours worked against hours available, overtime share and hours per unit
Capacity measures show whether the hours you have match the hours the work takes.
- Hours worked against hours available. Hours worked from timesheets, divided by hours available from the roster, x 100. Above 100 per cent means extra hours are covering a gap, and well below it means rostered time is going unused. Decision: rebalance the roster or recruit.
- Overtime share and agency labour percentage. Overtime hours divided by total hours worked, x 100, and labour hire hours divided by total hours worked, x 100. Both show how much of the work depends on hours outside the core roster. Decision: whether a gap is steady enough to hire for.
If you count output, add hours per unit (hours worked divided by units produced) to see whether extra hours are buying extra output. How much of the crew should be core, casual or labour hire is decided in the article on a flexible workforce model. When the numbers show a steady gap, Chandler Personnel provides labour hire and permanent recruitment for manufacturing employers and warehousing and logistics employers.
Overtime is also a safety measure. WorkSafe Victoria's fatigue guidance lists reviewing hours of work records and rosters among the ways to identify fatigue risks. The same page says the risk of musculoskeletal injury in manual tasks is significantly higher during a 12-hour shift than an eight-hour shift.
Reliability measures: absence rate, late starts and flexible shift fill rate
Reliability measures show whether the shift you rostered is the shift you got.
- Absence rate and late starts. Unplanned absence hours divided by rostered hours, x 100, and late starts divided by shifts worked, x 100. Work both out by shift and by day of the week, and keep planned leave out. Decision: where standby cover or a roster change is needed.
- Flexible shift fill rate. Flexible shifts filled divided by flexible shifts requested, x 100, taken from your own request log of overtime offers, casual shifts and labour hire orders. Decision: whether to ask earlier or widen your standby pool.
Absence can follow the season. The post on planning for winter absenteeism looks at using sick leave history and standby rosters in food and pharmaceutical plants. Chandler Personnel is available 24 hours a day, because blue collar staffing changes hour to hour. You can read how Chandler's process works on this site.
Stability measures: turnover rate and vacancy days
Stability measures show whether people stay and how long seats stand empty.
- Turnover rate. Leavers in the period divided by average headcount, x 100. Decision: if one role keeps losing people, find out why before you hire again.
- Vacancy days. The average number of days each vacancy stayed open, from approval to the replacement's first productive shift, for vacancies filled in the period. Decision: whether your hiring and training lead time is too long for your cover plan.
Forecasting leavers by role and tenure band is a different job, set out in the article on staff turnover planning for production and warehouse teams.
Capability measures: skills coverage and licence currency
Capability measures show whether the crew can run every station and hold the tickets the work needs.
- Skills coverage. Shifts where every station has a signed-off operator rostered, divided by shifts worked, x 100. Decision: who to cross-train next. The article on a skills matrix for manufacturing and warehouse teams shows how to build the sign-off list.
- Licence currency. Licences current on the roster date, divided by licences the roster requires, x 100. Decision: which renewals to book, and who cannot be rostered to a licensed task until they are renewed.
According to WorkSafe Victoria's high risk work licence page, a Victorian high risk work licence, including the forklift licence (LF), is valid for five years. A renewal can be applied for within 12 months of the expiry date, and a licence that expired more than 12 months ago needs proof of exceptional circumstances to renew. Keep an expiry date for every licence holder and flag renewals well before that date.
Set targets and trigger points, then review monthly
A target comes from your own baseline. WorkSafe Victoria's fatigue guidance takes the same approach to fatigue data: analyse it to set a baseline for monitoring changes and trends, over an adequate period of time. Work each measure out for the last several months, note the normal range, and set the target near it.
A trigger point is an alert level on one measure, tied to a named action. For example: if the absence rate on a shift stays above your baseline for two weeks running, review standby cover for that shift. Give every measure an owner, a trigger level and a first action. Building scenarios around demand swings is a separate job, covered in the article on workforce scenario planning.
Run the monthly review with three questions. Which measures crossed a trigger? What did each one prompt? Do the trigger levels still match the baseline? The review rhythm for the whole workforce plan is set out in the guide to workforce planning for manufacturers and warehouses.

Frequently Asked Questions
What KPIs should a manufacturing site manager track for the workforce?
Start with eleven measures: hours worked against hours available, overtime share, agency labour percentage, absence rate, late starts, flexible shift fill rate, turnover rate, vacancy days, skills coverage, licence currency and hours per unit. Together they cover capacity, reliability, stability and capability, and all of them come from the roster and payroll.
How do I calculate hours worked against hours available?
Divide hours worked by hours available, then multiply by 100. With illustrative figures, a crew rostered for 1,400 hours that works 1,540 hours scores 110 per cent. Above 100 per cent means overtime or extra shifts are covering a gap, and a result well below 100 suggests rostered time is going unused.
What is a healthy overtime percentage?
No single figure fits every site. Set the target from your own baseline for the last several months and from the fatigue limits you set after reviewing hours of work records and rosters. Overtime share is overtime hours divided by total hours worked, x 100.
How do I calculate the absence rate for a shift?
Divide unplanned absence hours by the hours rostered for that shift, then multiply by 100. With illustrative figures, a night shift crew rostered for 480 hours over four weeks that loses 36 hours to unplanned absence has a rate of 7.5 per cent. Leave planned leave out, and work the rate out for each shift separately.
How often should workforce KPIs be reviewed?
Review the set monthly, looking at each measure against its trigger level. Check the trigger levels themselves at the same meeting, because a baseline moves as your crew and volumes change. Record the decision each crossed trigger prompted, so the next review can check that it worked.
Measure the crew like you measure the line
Workforce KPIs for manufacturing turn the roster and payroll into decisions: eleven measures, each with a formula, a baseline and a trigger point. Review them monthly and change the action when a trigger is crossed. Start this week by working out hours worked against hours available for last month's roster, then add one measure at a time.
