As a growing business, do you know how much production capacity you’ll need to fulfillanticipated future demand and keep customers happy? That’s the essential questioncapacity planning aims to answer. It helps organizations estimate the equipment, materialsand people they’ll need to meet short-term and long-term demand — whileminimizing therisk of overinvesting in capacity. This comprehensive guide delves into capacity planningtypes, strategies, benefits and best practices.
What Is Capacity Planning?
Capacity planning is a process for analyzing how much production capacity organizations needto meet customer demand. It’s widely used in manufacturing and services industries.Capacity planning helps companies determine whether they have enough raw materials,personnel and equipment to meet forecasted demand. If demand is expected to increase in thefuture, businesses can use capacity planning to estimate how much additional productioncapacity they’ll need. Companies can also use capacity planning to determine whetherthey have the ability to take on new customer projects.
Capacity planning vs. resource planning:
The terms capacity planning and resource planning are sometimes used interchangeably —butthere are key differences between them.
Capacity planning is a strategic long-term approach that focuses onmatching supply with demand. Do you have all the resources you need to make whatcustomers want today, as well as what you’ll need in the future? Is a lack ofspecific resources restricting your overall capacity; did you turn away projectsbecause you’re understaffed or are lacking necessary equipment, for example?
Resource planning is a shorter-term approach that looks at theresources you have on hand and how you can best deploy them to meet your currentworkload. For example, a consulting firm might consider how to assign its staff tothe projects that best match their skills.
Key Takeaways
- Capacity planning helps organizations manage production capacity to meet customerdemand.
- This process also helps businesses determine whether they have enough resources, such assupplies, personnel and equipment.
- Businesses may choose different capacity planning strategies depending on factors suchas their overall business strategies, target markets and risk tolerances.
- Key capacity planning steps are forecasting demand, assessing current capacity and usingthat information to create a plan for the future.
Capacity Planning Explained
Capacity planning examines all the resources involved in production and estimates how much ofeach resource will be needed to meet demand. Resources include the people who perform thework, the raw materials and products used, equipment and facilities. The lack of a singleresource can constrain the company’s production capacity. For example, the company mayhave enough equipment and skilled workers, but if there’s a shortage of raw materials,it won’t be able to meet production targets.
Capacity planning involves many parts of the business and can be a complex process,especially when customer demand changes frequently and unpredictably. Overestimating thecapacity you’ll need may have expensive consequences. For example, a manufacturingbusiness may buy expensive new manufacturing equipment that lies idle because theanticipated customer demand doesn’t materialize. But underestimating capacity can alsobe problematic, leading to lost revenue, stockouts and customerfrustration.
How Does Capacity Planning Work?
Think of capacity as the maximum amount of work the business can complete in a given period.It may be calculated in various ways, depending on the company and the situation. Somecompanies may calculate capacity as the total number of employee work hours per week. Forexample, a consulting firm may have 25 employees who are each available for hire 40 hoursper week, for a total capacity of 1,000 work hours per week.
Other companies, including manufacturing businesses, calculate capacity in terms of output.Let’s say a dishware company has 25 employees who can each produce 15 boxed sets ofdishes per hour. If it’s operating 40 hours a week, without other constraints such asdowntime, its capacity would be 15,000 boxed sets of dishes per week.
Capacity planning attempts to answer the question of how to match that capacity toanticipated demand. How will demand for the consulting firm’s services change over thenext year, and how many consultants will it need to hire to meet that demand? Should thedishware firm invest in expanding production capacity to meet rising demand? Getting thoseanswers right can result in increased revenue and profits. But a mismatch between supply anddemand can lead to unused resources or an inability to fulfill orders.
History of Capacity Planning
The roots of capacity planning date back to the Industrial Revolution. With the transitionfrom an agricultural to an industrialized society, product consumption increased andmanufacturers started trying to anticipate demand.
During the 20th century, new manufacturing techniques enabled enormous increases inproduction capacity, helping to satisfy rapidly growing consumer demand. Henry Ford famouslyintroduced assembly lines to cut production time for the Model T from 12-plus hours to 90minutes, helping to propel the worldwide consumer adoption of automobiles.
Early attempts at capacity planning relied on manual methods that were extremelylabor-intensive. More recently, capacity planning has been transformed by technology.Capacity planning software can consider multiple variables, including demand forecasts, toestimate the capacity required. Technology also makes it much easier to respond quickly toshifts in demand or supply constraints.
Types of Capacity Planning
Capacity planning typically focuses on three key resource categories: materials, workforceand equipment.
Products and materials capacity planning.
Do you have enough materials or other items to fulfill anticipated orders? Forexample, a plant nursery needs enough flowers, trees, shrubs, seeds and soil to meetthe demands of its customers. A manufacturer needs enough raw materials to feed itsproduction processes.
Workforce capacity planning.
This ensures businesses have enough people and work hours available to complete jobsin a timely manner. It also helps determine when you need to adjust the size of theworkforce.
Equipment/tools capacity planning.
This aims to make sure that production capacity isn’t held back by a lack ofequipment. It analyzes the quantity of tools and other equipment needed to meetprojected demand. The equipment may include machinery, forklifts, assembly linecomponents, computers and anything else needed to manufacture the company’sproducts.
Capacity Planning Strategies
Capacity planning isn’t a one-size-fits-all approach. Choosing a particular capacityplanning strategy depends on factors such as the company’s growth targets, risktolerance and the kind of products it makes.
Lead strategy.
This aggressive strategy calls for expanding capacity in anticipation of increasedfuture demand. Manufacturers often use lead capacity planning when they’reaiming to win market share against competitors. If your lead strategy positions youas the only company with a large supply of a product in high demand, you may enjoy aboost in profit and market share. However, a lead capacity planning strategy can berisky if demand doesn’t grow as expected.
Lag strategy.
This is a more conservative capacity planning approach. Lag capacity planning focusesfirst on meeting current demand. Only when the company is already operating at itsmaximum capacity does it add more capacity if demand continues to grow. Thisstrategy lessens the risk of overinvesting in production but also increases thechances of losing revenue and experiencing stockouts.
Match strategy.
This moderate strategy, also known as tracking strategy, mixes in elements of bothlead and lag strategies. Match planning adjusts capacity by small amounts inresponse to market trends, as opposed to committing to a big capacity expansion inanticipation of demand growth (lead strategy) or waiting until you have alreadyreached your maximum capacity (lag strategy).
Adjustment strategy.
This strategy relies on planning tools that analyze multiple variables, such asdemand forecasts, real-time sales data and seasonal trends. The goal is to moreaccurately adjust capacity in advance of demand. For example, if demand hashistorically exceeded capacity during the summer, the company may plan to increasecapacity during those months.

Benefits of Capacity Planning
Capacity planning can deliver many benefits, including lower costs, higher customersatisfaction and a clearer view of future requirements. More specifically, this planningprocess can:
Reduce operational costs.
Capacity planning facilitates more accurate budgeting and helps minimize waste. Ithelps companies ensure they’re investing the appropriate amount in materials,equipment, facilities and staff. Capacity planning can also help companies identifypotential bottlenecks and other resource problems, so they can adjust operations toincrease efficiency.
Achieve on-time delivery.
Effective capacity planning means that adequate resources are available for each job,helping to ensure that production stays on schedule. You can fulfill orders on timeand keep customers happy.
Avoid stockouts.
Good capacity planning means companies are better able to match supply to demand. Itreduces the chance that you’ll run out of in-demand products, which can leadto customer frustration and lost business.
Inventory skill sets.
Part of capacity planning involves spelling out the skills needed to make yourcompany’s products. A good plan forecasts skill requirements and incorporatesany training needed for employees as well as expertise you’ll need to acquirefrom outside sources.
Provide a blueprint for growth.
Capacity planning provides a blueprint for the company’s future expansion. Itdetermines the facilities, equipment and people you’ll need to meet demand asthe company grows. That helps you plan your growth over time. For example, you canbetter identify potential new locations that offer the resources you need.
3 Steps to Capacity Planning
Capacity planning can be divided into three broad steps: What capacity do I need? What do Ialready have? And what changes are needed going forward?
Assess capacity requirements.
How much capacity will you need to meet your anticipated demand, and when will youneed it? How many items will you need to make in a day? Consult your forecasts andproduction schedule to help determine how much production capacity you’llneed.
Understand current capacity.
Understanding current capacity provides a realistic expectation of what the companycan produce. This requires an analysis of the company’s actual performance,not just its theoretical maximum capacity. How efficiently does the company use itscapacity? Does it achieve a consistent level of use or is performance inconsistent?Analyze actual versus predicted process performance and calculate which parts ofeach process take the most time.
Create a plan for the future.
After analyzing your current capacity, it’s time to determine how you’llmove forward. Do you need additional capacity to meet demand? How much? Look atalternatives for adding capacity, such as adding equipment, streamlining workflowsor expanding the workforce. Considering different scenarios based on demandforecasts and actual demand can help determine the production plan that’s mostlikely to meet demand with the lowest risk.
Capacity Planning Examples
A company makes pool toys and related products, including inflatable pools, rafts, beachballs, goggles and kickboards. Demand is seasonal, expanding in summer and shrinking inwinter. So the company examines historical data and current market trends to estimate thecapacity it will need. The historical data shows how many of each item the company producedand indicates whether that production resulted in excess products or a shortage.
Based on its research, the company sets a goal of producing 40,000 items in each productcategory. Its production process can make only one type of product at a time. Historicaldata indicates that the company can consistently achieve the following hourly productionrates:
- Inflatable pools: 25 per hour
- Rafts: 50 per hour
- Beach balls: 100 per hour
- Goggles: 40 per hour
- Kickboards: 50 per hour
The company aims to keep its staffing and equipment resources the same as in the past: 50employees who each work 30 hours a week, totaling 1,500 work hours per week.
Based on the project requirements that call for producing 40,000 of each item, here’show much capacity the company needs:
- Inflatable pools: 40,000 / 25 = 1,600 work hours needed
- Rafts: 40,000 / 50 = 800 work hours needed
- Beach balls: 40,000 / 100 = 400 work hours needed
- Goggles: 40,000 / 40 = 1,000 work hours needed
- Kickboards: 40,000 / 50 = 800 work hours needed
That’s 4,600 total work hours needed. Since employees work a total of 1,500 hours perweek, this project would take a little more than three weeks to complete.
That timeline doesn’t account for potential hiccups along the way, such as supply chaindelays, unplanned resource changes, equipment breakdowns or employee absences. Plus, thecompany needs to factor in the amount of time it takes to change out the materials andreconfigure equipment for each product. So, the final plan may call for about four weeks orpossibly even more to complete production.
8 Capacity Planning Best Practices and Tips
Capacity planners must determine the appropriate way to balance resources and demand. Hereare some best practices to help with the balancing act.
Analyze current resources.
Get an accurate picture of your current capacity and the resources at your disposal.This provides a basis for determining how much capacity you’ll actually needto handle demand.
Aim for the right mix of skills.
Cross-functional teams that include a mix of planning, business and operationalskills can bring the diverse perspectives needed to understand current capacity andhow to meet future requirements.
Prioritize projects.
Focus on the most important projects first. Which orders are the most time-sensitive?What must be done right away to meet demand?
Track operational productivity.
Are tasks taking longer than planned? If so, why? Are delays due to unrealisticscheduling or are there other problems? Gathering this real-world data can help youbetter budget time for future jobs.
Pinpoint bottlenecks.
Is production held up by specific process steps or the lack of a single resource?Look for ways to restructure resources to eliminate any bottlenecks.
Focus on communication.
Staying in touch with all stakeholders helps to manage expectations and enable thecompany to make adjustments to accommodate any operational hitches.
Monitor risks.
Look for risks, such as potential supply-chain problems and rising costs. Identifyingpotential problems early allows the company to factor them into capacity plans.
Expect change.
It’s all too common to experience events that require a change in plan —aninaccurate estimate, a lack of a key raw material, a machine failure. A realisticapproach to capacity planning recognizes that the company is not immune to theseproblems.
4 Common Capacity Planning Issues
Capacity planning is often a complex process that involves collaboration among multiplestakeholders and gathering information from across the company. Here are some potentialproblems to watch out for:
Data collection.
Capacity planning involves combining data from multiple sources, including internalgroups such as sales, manufacturing and finance, as well as external informationabout market trends. Not all of this information may be easy to obtain. That canmake it difficult to quickly build a consolidated, up-to-date view of currentcapacity use and determine how much capacity the company needs.
Data quality.
Data combined from multiple sources can be of inconsistent quality and in a varietyof different formats. Some data may contain errors, especially if it’s beencollected manually. Other information may be out of date.
Calculation accuracy.
Capacity planning can involve complex calculations that factor in materials, people,equipment, market demand forecasts and more. Accuracy is essential to ensure thecompany doesn’t underestimate or overestimate the capacity it needs to meetdemand. But it’s easy to make errors, especially if data is drawn from manysources and the calculations are performed manually using spreadsheets.
Collaboration.
There are so many people involved in capacity planning, both internal and external,that it can be challenging to keep everyone in sync. Production teams may not bekept up to date with information about new projects and sales that affect the amountof capacity the company needs. Further adding to the challenge: Some information mayneed to be communicated externally to suppliers and customers.

Capacity Planning FAQs
What are the three steps of capacity planning?
The three steps of capacity planning include determining how much capacity will be required,assessing your current capacity and planning how to expand current capacity to meet demand.
What is a capacity planning example?
You own and operate a bakery with four other employees and you all work five eight-hour days.That’s a total of 200 work hours per week. You know that the bakery generates 150cookies and five cakes per hour using three ovens. That means your maximum capacity, basedon continuous operation during working hours, would be 1,200 cookies and 40 cakes per day,and 6,000 cookies and 200 cakes per week. This provides the bakery owner with a basis forunderstanding how many supplies the shop should order to meet demand. The owner needs toconsider factors that can impact production, such as staff absences and supply problems.Should the demand increase beyond the bakery’s current capacity, the owner could addanother oven, increase its staff or pay overtime.
What are the four capacity planning strategies?
The four primary capacity planning approaches are the lead, lag, match and adjustmentstrategies. The lead strategy is an aggressive approach to expanding capacity in advance,based on anticipated demand. The more conservative lag strategy focuses on meeting actualdemand; the company only expands its capacity when it’s already running at fullcapacity and sees an increase in demand. Match strategy is a moderate approach that combineselements of the lead and lag strategies, increasing capacity incrementally in response tomarket trends. Adjustment strategy applies demand and supply planning tools that considermultiple factors, including historical demand, seasonality and sales forecasts.
What is capacity planning in operations management (OM)?
Capacity planning in OM balances product demand with a company’s ability to meet thatdemand. The object is to optimize cost and operational effectiveness.
