How a Ceramics Manufacturer Reduced Staffing-Related Production Downtime: A Workforce Planning Case Study
Manufacturing Workforce Planning
The 5 Phases of Reducing Staffing-Related Downtime
When the Kiln Is Ready but the Operator Isn’t — Cutting Staffing-Related Downtime in Ceramics
The glazing line is set up, orders are waiting, and the one employee trained for a critical step called in sick. The shift has plenty of people on paper, but nobody who can safely do that job. Production stalls anyway.
The 60-Second Version
- Staffing downtime isn’t only about headcount. It’s about having the right skills at the right time.
- Five phases: pinpoint causes, forecast demand, cross-train, plan shifts and coverage, then retain experienced staff.
- Cross-training must never mean unprepared people on unfamiliar or hazardous equipment.
- This is an illustrative case. No downtime reduction is claimed.
- Want to act now? Jump to the first steps.
Ceramics production moves through coordinated stages: raw material preparation, forming, drying, firing, glazing and quality inspection. Each needs people with the right skills. When positions go unfilled or experienced workers are unavailable, you can see delayed tasks, more overtime, uneven workloads and interruptions between stages that affect equipment use and deliveries. Equipment failures and material shortages cause downtime too, but workforce-related interruptions need a different approach. This case explores how a manufacturer could address them through forecasting, cross-training, better shift planning and employee development.
Important note: this is an illustrative case study. It demonstrates practical HR strategies without claiming that a specific company achieved a verified reduction in downtime.
The Challenge: Production Delays Caused by Staffing Gaps
Absences, vacancies and thin coverage for specialized tasks made it hard for supervisors to put people where they were needed. Some activities depended on workers with specific technical experience, and others couldn’t always take over safely without additional training. The problem went beyond the number of employees on the payroll: the plant needed to know whether it had the right skills available at the right time.

It isn’t just about enough employees on each shift. It’s about the right skills.
— The case study’s core lessonHR and production need one coordinated plan covering schedules, availability, training and priorities.
Headcount vs. Skills Coverage
A shift can look fully staffed and still be unable to run.
Headcount only
Counting people on the roster
- Every delay blamed on labor shortages
- Specialized tasks rest on one or two people
- Last-minute rearranging of workloads
- Repeated overtime for the same employees
- No view of backup coverage
Skills coverage
Planning around critical roles
- Causes separated from equipment and material issues
- Skills matrix shows who can cover what
- Scenario plans for peaks and absences
- Trained, authorized backups for essential roles
- Overtime reviewed for recurring gaps
The 5 Phases of Reducing Staffing-Related Downtime
1
Find causes
Separate staffing delays from everything else
Review shift attendance, vacancy records, overtime, production logs and supervisor reports. For each interruption, record the time, location, affected activity and immediate cause, so staffing gaps can be distinguished from equipment breakdowns, maintenance delays and material shortages.
This creates a baseline and stops every delay being blamed on labor shortages.
2
Forecast
Align workforce plans with production demand
HR and production managers review expected output, shift patterns, availability, planned leave and skills needed per stage, distinguishing general labor from specialized roles. Plan for normal production, peak demand and unexpected absences to see where recruitment, temporary cover or redeployment might help.
CIPD guidance describes workforce planning as balancing the supply of people and skills with organizational demand.
3
Cross-train
Reduce dependence on a few experts
Identify critical tasks that are hard to cover and build training plans for suitable employees, with demonstrations, supervised practice and assessment before independent work. A skills matrix records who has completed which training and their authorized level of responsibility, and reveals departments where only one or two people hold an essential skill.
Never assign unfamiliar machinery or hazardous processes without proper preparation. NIST’s Manufacturing Extension Partnership supports developing employees rather than relying only on outside hiring.
4
Shifts & coverage
Make absence cover a documented process
Set clear procedures for recording availability, requesting leave, reporting absences and arranging replacements. Review upcoming shifts for gaps in essential roles and assign trained, authorized backups. Watch overtime patterns, since asking the same people repeatedly may cover shortages briefly but adds fatigue and further absences.
If gaps recur, ask whether recruitment, revised schedules or more training is the answer.
5
Retain & engage
Keep the experience you already have
Review feedback, exit interviews, attendance trends and turnover by department for concerns about workload, shifts, supervisor communication, recognition or skill development. Respond with clearer communication, fairer scheduling, structured training, recognition and visible career paths into specialized or supervisory roles.
Persistent understaffing shouldn’t be solved by simply extending hours or adding pressure.
Measuring the Impact of Workforce Planning
Compare staffing-related downtime to a clearly defined baseline, and track frequency and duration of workforce interruptions, unfilled shifts, absence rates, overtime hours, training completion, turnover and trained backup coverage for critical roles.
Keep measurements consistent across periods. Production volume, product mix, maintenance schedules and material availability also affect downtime, so weigh them before crediting workforce planning. And check sustainability: lower downtime paired with heavy overtime or rising safety concerns means the plan needs adjusting. Any specific reduction figure should be published only if company records or a credible source verify it and explain how it was measured.
Downtime that falls while overtime and safety concerns rise isn’t a win.
Where HR Software Fits In
When availability, skills, training and shift coverage live in separate records, planning gets complicated. HR software can centralize workforce information for authorized managers. Scheduling features may support shift allocation, leave requests and absence records, while skills and training records show who is qualified to cover which roles and where more training is needed. Reporting tools help HR compare staffing levels, overtime, turnover and absenteeism across departments and review them alongside production data.
But HR software can’t independently solve staffing shortages. You still need reliable processes, accurate information and managers who act on what the data shows. The right system supports operational decisions rather than replacing them.
4 Lessons for Ceramics Manufacturers
Key takeaways
What every ceramics manufacturer can use
01Know critical skills

Downtime can’t always be eliminated, but you can prepare.
04Use both data sets
Evaluate with workforce and production data together.
How to Start: 3 Steps
1
Log every interruption’s cause for a few weeks
Record time, location, activity and whether staffing was the cause.
2
Build a simple skills matrix for critical roles
Flag tasks where only one or two people are qualified.
3
Pick one gap and plan safe, supervised cross-training
Include assessment before independent work.
Frequently Asked Questions
How can understaffing cause production downtime in ceramics?
It can delay activities when essential operators, technicians or quality-control staff are unavailable, interrupting flow between stages, delaying shift handovers or holding tasks until a qualified employee is available.
What is workforce planning in manufacturing?
It matches staffing levels and employee capabilities with current and future operational needs, including forecasting labor demand, identifying skill gaps, planning recruitment and training, and reviewing performance over time.
How does cross-training help reduce staffing-related delays?
It prepares suitable employees to perform additional tasks within their competence, so trained colleagues may cover an absence without waiting for an external replacement, provided the work can be reassigned safely and appropriately.
Final Thoughts
Staffing-related downtime is both an operational concern and a workforce planning challenge. Identify recurring gaps, forecast production needs, cross-train employees and set reliable shift coverage procedures.
Retention and wellbeing matter too, because experienced workers carry valuable technical knowledge. Treat workforce planning as an ongoing partnership between HR and production, and base any claim of improvement on verified company data.
