Manufacturing productivity is often linked to how smoothly machines run, the availability of raw materials, and production capacity. Yet production bottlenecks can just as easily stem from poor workforce planning.
Without solid planning for how many workers production activities actually require, operational stability suffers. The existing headcount may simply fall short of what production demands, and limited skills among workers operating machinery add another layer of friction to productivity.
Companies need to identify these issues before production begins, so smaller problems do not snowball into bigger ones.
Workforce planning offers a strategic way to align production needs with headcount, shift schedules, actual working hours, skills, and labor costs.
With the help of technology such as HRIS, all the data a company needs can be integrated in one platform, allowing HR and operations management to make decisions that are faster, more accurate, and based on data.
Key Takeaways
- Workforce planning in manufacturing is a systematic process for planning a plant’s labor needs, covering headcount, skills, placement, work schedules, costs, and succession readiness.
- It matters to manufacturers because it keeps production running smoothly, surfaces skill gaps, aligns labor needs with changing technology, optimizes shift schedules, supports data-driven management decisions, and helps companies stay competitive.
- To build it, companies need to project production for the next 6-12 months, calculate actual working hours, build a skill matrix that closes bottleneck risk, define strategies for closing skill gaps, and evaluate the plan regularly.
What Is Workforce Planning in the Manufacturing Industry?
Workforce planning in the manufacturing industry is a systematic process for planning a plant’s labor needs, one that determines headcount, skills, placement, work schedules, costs, and succession readiness.
This process is built around production targets, line capacity, shift schedules, skills, and labor costs. Manufacturing workforce planning needs to connect directly to data from plant operations.
That way, a company has the right people, with the right competencies, on the right production line, at the right time.
This aligns with how CIPD (2025) defines workforce planning as the process of balancing labor supply with labor demand.
Building it out requires analyzing the current labor supply, projecting future labor needs, identifying the gap between today’s workforce and tomorrow’s requirements, and deciding on solutions that help the company reach its strategic plans.
In manufacturing, labor needs are heavily shaped by production volume, skill levels, and shifting skill requirements. On top of that, the ongoing growth of the manufacturing industry itself keeps pushing labor demand higher.
According to the Deloitte and The Manufacturing Institute Talent Study (2024), which looked at conditions in the United States, manufacturing is affected not only by skill gaps but also by a shortage of applicants for open positions.
Growth in the manufacturing sector is driving up demand for labor across every level, from entry-level roles to highly skilled ones.
The same study notes that the manufacturing sector could need around 3.8 million new workers between 2024 and 2033. If companies cannot find ways to close the skill gap and applicant gap, roughly 1.9 million positions could go unfilled.
This is exactly why workforce planning is so important in manufacturing, as it directly impacts plant productivity. Companies need to align business, operational, and HR needs to build a workforce that is both skilled and productive.
Why Is Workforce Planning Important for the Manufacturing Sector?
Plant productivity is not determined by smoothly running machines alone. Production can still stall if shifts go unfilled, operators lack the right skills, or overtime climbs too high because of understaffing.
The WEF (2025) points out that workforce stability and productivity are key factors behind long-term success in manufacturing.
The same report notes that 71% of US manufacturers face workforce stability issues, while companies that invest in frontline talent saw a 52% improvement in stability metrics, 34% in financial metrics, and 28% in productivity and operational health and safety metrics.
A local example comes from a case study at PT Sunthi Sepuri. Research by Sukirman, Mashabai, and Adiasa (2021), published in the journal Performa: Media Ilmiah Teknik Industri, found a potential imbalance in operator workloads within the company’s production department.
The study found that operators running the Compressing 4 and Blistering machines were overloaded by 192% and 297%, respectively. These figures came from the Full Time Equivalent (FTE) method, which factors in total activity time, allowance time, and working time. The finding shows that staffing at certain workstations simply was not enough to carry the existing production load.
This is why workforce planning matters. It helps keep the workforce stable and ensures production needs are met in a more deliberate way. It also helps companies anticipate labor shortages, balance workloads, and head off operational problems before they take a bigger toll on plant productivity.
Here are a few reasons why workforce planning matters so much to the manufacturing sector.
1. Keeping Production and Operational Capacity Running Smoothly
A shortage of operators, technicians, or supervisors can have a major impact on production delays, workload buildup, excessive overtime, and lower output.
Workforce planning helps companies make sure every production line has enough people to match production targets, shift schedules, and operational capacity.
2. Closing the Skill Gap and Applicant Gap
Manufacturing does not just struggle with a shortage of skills. It also struggles with a shortage of candidates applying for open roles.
Workforce planning gives companies a way to map existing skills, spot missing ones, define training needs, plan recruitment strategy, and prepare succession plans for strategic roles.
To help with this, you can use LinovHR’s competency management service. It lets you identify the skills employees hold in every position, then analyze the gap between those skills and the standards your company has already set.
Once you have that analysis in hand, you can plan the right development path for employees based on what production actually needs.
3. Adjusting Labor Needs to Keep Pace with Technology
As technology keeps advancing, companies are under pressure to adopt new tools that speed up production. Systems that once needed constant human intervention can now run entirely on digital, automated processes.
Because of this, workforce planning should not be viewed only as a way to figure out headcount. It also works as an analytical tool for identifying which skills the company needs to prepare for.
Without this kind of planning, a mismatch can grow between what production technology demands and what the available workforce can actually deliver.
4. Optimizing Shifts, Overtime, and Workload
Manufacturing often runs on shift systems, daily production targets, and labor needs that shift along with market demand. Without solid workforce planning, companies risk lopsided schedules, understaffed shifts, excessive overtime, or workloads that are spread unevenly.
Workforce planning helps HR and operations management build more balanced schedules, keep overtime in check, and make sure production needs are met without sacrificing employee wellbeing.
5. Supporting Flexibility and Data-Backed Decisions
Good workforce planning helps a company know who is available, who holds specific skills, who can be shifted to another production line, and which positions are at risk of sitting empty.
With that data, HR can shape decisions on recruitment, training, promotions, shift changes, and retention strategy, all grounded in more accurate workforce data.
6. Preserving Manufacturing’s Competitive Edge
In Indonesia, the manufacturing sector plays a major role in the economy. According to data from BPS, the processing industry contributed 19.07% of national GDP in 2025, making it the largest contributor of any sector.
Given how large that role is, workforce problems in manufacturing do not just affect a single company. They ripple out to the productivity of the entire industry.
Workforce planning helps companies maintain production stability, improve efficiency, reduce the risk of labor shortages, and keep technology transformation moving in step with workforce readiness.
Challenges in the Manufacturing Industry
Manufacturing faces plenty of HR management challenges that are far from minor. Every decision HR and management make can directly affect a company’s operational stability.
Based on issues found among LinovHR clients such as Omron and Krama Yudha Ratu Motor (KRM), managing shift schedules and overtime stands out as one of the biggest challenges in manufacturing. Large headcounts, varied production lines, and constantly shifting operational needs all push companies toward a more structured way of managing work schedules.
The challenge grows because shift changes in manufacturing tend to move quickly to keep up with production needs. When shift and overtime management falls apart, companies risk payroll calculation errors, and that risk only grows larger for companies still relying on manual systems.
Even LinovHR clients with existing systems often experience friction when those systems are not integrated. As a result, shift schedules, attendance records, overtime, and payroll data remain scattered across multiple platforms, requiring HR teams to spend valuable time manually reconciling and verifying information.
Here are some of the common problems manufacturing companies run into.
1. Complex Shift Schedules Prone to Gaps
Plants that run around the clock depend on shift systems to keep production moving smoothly, and this is a challenge manufacturing companies deal with constantly.
An unfilled shift, overlapping leave requests, or a sudden absence can all disrupt production simply because there is no one available to cover the gap.
The challenge grows even bigger when HR still manages shift schedules manually, even though HR’s role in aligning production needs with headcount, working hours, leave, overtime, and attendance is genuinely important.
Manual systems carry a high risk of data errors, which eventually disrupt the plant’s production process. Without accurate attendance and time management data, it is hard for a company to spot early on whether a particular shift is understaffed.
2. Limited Skills Across Production Lines
A large headcount alone does not guarantee smooth production. In manufacturing, every production line calls for a different set of skills, and certain machines, processes, or work areas can only be handled by employees with specialized skills.
When only a handful of employees know how to run a particular machine, the company ends up relying heavily on the same few people. The moment one of them takes leave, calls in absent, resigns, or gets moved to another line, production can stall because there is no one else with equivalent skills to step in.
3. Excessive Overtime Practice
In manufacturing, overtime is a common way to handle rising production targets. In the short run, overtime is a practical fix for chasing higher output, but when it becomes constant, it usually signals understaffing or messy shift management underneath.
Excessive overtime also carries real consequences, from ballooning labor costs and worker fatigue to a higher risk of workplace accidents and declining output quality. It needs to be managed carefully, because overtime is already governed by labor regulations.
Under Indonesian Government Regulation (PP) No. 35 of 2021 about Fixed Term Employment Agreements, Outsourcing, Working Hours and Rest Periods, and Termination of Employment, Article 26 paragraph (1) sets overtime at a maximum of 4 hours per day and 18 hours per week.
Companies that require employees to work beyond normal hours must pay overtime wages at 1.5 times the hourly rate for the first hour and 2 times the hourly rate for each additional hour.
This regulation makes clear that overtime cannot be managed carelessly. Companies need clear overtime records so working hours stay within the rules and payroll calculations remain accurate.
Data Needed to Build Workforce Planning
Building workforce planning requires complete, integrated labor data. HR teams need visibility into headcount by position, shift schedules, attendance, leave and overtime data, employee skills, training needs, turnover rates, payroll data, and labor costs.
This data gives HR teams a foundation for knowing whether current headcount and skill levels actually match what the production process needs.
CIPD (2025) explains that workforce planning covers analyzing the current workforce, defining future labor needs, identifying the gap between the two, and developing solutions that help a company reach its targets.
Here is the data companies need when building workforce planning.
| Data Needed | Benefit |
| Headcount | Identifies how many workers are on each production line, department, or plant branch |
| Organizational structure | Shows role divisions, job titles, reporting lines, and key positions within operations |
| Shift schedule | Confirms that every shift has enough staff to meet production needs |
| Attendance data | Reveals attendance patterns, tardiness, absences, and potential staffing gaps |
| Leave and permission data | Prevents overlapping leave that could leave a production line understaffed |
| Overtime data | Shows whether overtime patterns stem from a production spike or genuine understaffing |
| Skill data | Identifies which employees can operate specific machines, processes, or production lines |
| Training needs data | Shows training, development, and readiness needs for employees to fill certain roles |
| Turnover data | Flags positions or divisions most prone to losing staff |
| Payroll data | Calculates how labor needs affect salary, benefits, incentives, and overtime costs |
| Labor cost | Helps companies plan workforce needs without overloading operational costs |
How to Build Manufacturing Workforce Planning
Here is a guide to building workforce planning that keeps plant productivity running smoothly.
1. Set a Production Projection
The first step in building manufacturing workforce planning is understanding production needs. Companies need to know their production targets for the next 6-12 months, based on output volume, product lines, process types, and specific time periods.
This projection helps HR and operations teams calculate how many workers each production line will need. For example, when product demand rises during a particular period, the company can estimate its need for operators, technicians, supervisors, and support staff well in advance.
CIPD (2025) explains that setting future projections shapes human resource needs and helps companies build production targets that support their future goals.
2. Calculate Actual Working Hours
Once the production projection is set, companies need to calculate workforce capacity based on actual working hours. This calculation has to account for leave, sick days, training, machine downtime, maintenance, moves between work areas, and other nonproduction activities.
Calculating actual working hours lets a company make the most of the workforce capacity it already has. This matters because having enough employees on paper does not automatically translate into enough usable working capacity.
A production line might have what looks like enough operators, but if some of them are on leave, in training, or affected by machine downtime, effective working hours drop. That is why calculating actual working hours helps a company avoid labor shortages that could throw off production targets.
According to a Journal of Integrated System (JIS) article titled Workload Analysis with Full Time Equivalent Method to Optimize Production by Santika Sari and colleagues (2022), the actual working hours calculation converts total working hours into the number of workers needed to complete a given job.
The calculation follows standard time, meaning a work duration that already factors in adjustment and allowance time.
For example, say a production line has 25 operators working 8 hours a day over 22 working days in a month. Total available working hours would be 25 operators x 8 hours x 22 days, which = 4,400 working hours per month.
From that total, the company needs to subtract hours that are not actually spent on production, such as leave, sick days, training, machine downtime, briefings, and moves between work areas.
4,400 working hours per month – 200 hours (leave, permission, sick days) – 80 hours (training) – 160 hours (downtime and maintenance) – 60 hours (nonproduction activities) = 3,900 hours.
That calculation shows the actual working hours available from employees come to 3,900 hours. This gives HR teams a foundation for workforce planning that looks beyond headcount alone to the actual working capacity on hand.
3. Build a Skill Matrix to Close Bottleneck Risk
Not every employee in manufacturing brings the same skill set. Certain machines, processes, or production lines can only be run by workers with specialized skills, which is exactly why companies need to build a skill matrix that maps out what every employee can do.
One useful framework here is the 9 box matrix, a tool that groups employees by potential and performance level. Each of those groups gives management a clearer basis for making decisions.
A skill matrix helps a company see who can operate a given machine, who could step in as a backup, and who still needs training. With this data, HR and supervisors can place employees more precisely based on what production actually requires.
To make mapping workforce skills easier, companies can use a simple skill matrix like the example below.
4. Define a Strategy to Reduce the Skill Gap
Once a skill gap becomes visible, the company needs a strategy to close it. That strategy could involve internal training, new recruitment, cross-training, mentoring, contract labor, or temporary overtime if the need is only short-term.
Choosing the right strategy depends on how long the need will last, the skill level involved, and cost. If the gap is long-term and tied to a critical position, internal training or new recruitment is usually the better route. But if the need only stems from a temporary production spike, contract labor or overtime can do the job.
A WEF (2025) report notes that, on average, 39% of workers’ current skills are expected to become obsolete between 2025 and 2030, which makes upskilling through training a real necessity.
5. Evaluate Workforce Planning Regularly
Workforce planning needs regular evaluation because production needs in manufacturing shift often. A production projection might miss the mark, market demand might spike, machines might go down, or absenteeism might climb during a particular period.
A monthly review helps a company compare its workforce plan against what is actually happening on the floor. HR and operations teams can check whether headcount is on target, whether overtime is still running high, whether any shifts sit empty, and whether the skill gap is starting to close.
Regular evaluation helps a company adjust labor needs based on the latest data, which makes recruitment, training, shift scheduling, and cost calculations more accurate across the board.
Workforce Planning Metrics to Watch
| Metric | Function | What to Watch | Promblem Indicators |
| Headcount per shift | Confirms every shift has enough workers to meet production needs | Active employees per shift, labor needs per line, and open positions | Shifts are frequently understaffed, production targets are missed, or supervisors must reassign employees on short notice |
| Overtime rate | Measures how much the company depends on overtime to hit production targets | Total overtime hours, overtime frequency, departments with the highest overtime, and overtime cost | Overtime keeps climbing, labor costs balloon, and employees face a rising risk of fatigue |
| Absence rate | Tracks labor availability and patterns of employee absence | Daily attendance, tardiness, permission leave, sick days, and absence patterns tied to specific shifts | Production suffers because too many employees are absent, especially on certain lines or during certain periods |
| Skill coverage | Shows how many employees can run a specific machine, process, or production line | Number of employees with critical skills, backup employees, and production lines mastered by only a handful of people | A bottleneck appears whenever one of those employees takes leave, resigns, or is absent, because no one else can step in with the same skill |
| Training | Measures how well training programs are closing the skill gap | Percentage of employees who complete training, type of training, and post-training evaluation results | The skill gap is not shrinking, employees are not ready for new roles, or training is not moving the needle on productivity |
| Turnover rate by position | Identifies which positions or work areas lose employees most often | Number of resignations, positions with high turnover, employee tenure, and reasons for leaving | Critical positions sit empty often, recruitment costs rise, and production suffers from the loss of experienced workers |
| Labor cost | Measures how efficiently HR spending aligns with production needs | Salary, overtime, benefits, incentives, recruitment cost, training cost, and total labor cost | Labor costs rise without a matching increase in productivity or production output |
| Productivity per employee | Tracks each worker’s contribution to production output | Output per employee, output per shift, and progress toward production targets | Headcount grows, but output does not increase proportionally |
| Labor to output ratio | Measures whether headcount is balanced against production volume | Employee count compared with production units, batches, or output targets | One line ends up overstaffed while another runs short |
| Critical positions without backup | Reveals the risk of relying too heavily on specific employees | Critical positions, number of backup employees, and internal succession readiness | Production stalls when one key person is unavailable and no ready replacement exists |
The Role of HRIS in Supporting Manufacturing Workforce Planning
An HRIS helps companies build workforce planning by integrating key data such as shift schedules, attendance, overtime, payroll, and employee skill analysis. This gives HR teams a way to plan labor needs more accurately and in step with how the company actually operates.
Here is how an HRIS supports workforce planning.
1. Integrating Shift, Attendance, Overtime, and Payroll Data
An HRIS acts as a system that brings HR operational data together on a single platform. Shift schedules, attendance, tardiness, leave, overtime, and payroll all need to be integrated so HR can see the full picture of the workforce.
CIPD (2025) explains that people analytics helps organizations make evidence based decisions by drawing insight from employee data, HR policy, and work practices. This is exactly why integrating shift, attendance, overtime, and payroll data matters. It lets HR make more accurate workforce planning decisions.
With integrated data, HR can see workforce availability for every shift, spot production lines that are chronically understaffed, and monitor overtime needs. This matters because overtime that keeps climbing can be an early signal that headcount is not keeping pace with production.
Payroll integration also lets a company see the direct cost impact of its workforce decisions. HR does not just know who showed up or worked overtime. It can also calculate how that affects salary, benefits, incentives, and overall labor operating costs.
2. Connecting Competency Management and LMS
An HRIS also supports workforce planning by linking competency management with a Learning Management System (LMS). Competency management helps a company map out employee skills, while the LMS delivers the training needed to close whatever gaps that mapping reveals.
Skill mapping matters because it shows who already holds a particular skill, who could serve as a backup, and who still needs training.
If competency management shows that only a few employees can run a particular machine, the LMS can be used to design training for everyone else.
This approach plays an important role in preparing the workforce for changes in production technology.
3. Using HR Analytics to Catch Risk Early
An HRIS also helps companies use HR analytics to catch productivity problems early. Workforce data, once collected, can be analyzed to spot warning patterns before they take a heavy toll on plant operations.
Rising overtime, for instance, points to understaffing. High absenteeism suggests a workload problem or a shift schedule that is not working. Rising turnover can signal a retention problem. And declining performance can point to a need for training or a fresh look at job placement.
HR analytics lets HR see how attendance, overtime, turnover, competency, and productivity connect to one another. That data helps a company act faster, whether that means adding headcount, restructuring shifts, rolling out training, or fixing its retention strategy.
Conclusion
Workforce planning plays a critical role in keeping manufacturing operations running smoothly. With the right approach to workforce planning, a company can keep headcount, shift schedules, skills, working hours, and labor costs aligned with what production actually needs.
Building workforce planning also depends on accurate data, from production projections and actual working hours to skill matrices and regular evaluation. That foundation lets a company anticipate risks such as empty shifts, skill gaps, excessive overtime, and ballooning labor costs.
For this process to work effectively, companies need a system that can connect workforce data in one central place. This is exactly where an HRIS comes in, helping HR and operations management build workforce planning that is faster, more accurate, and grounded in data.
