Accurate workforce forecasting helps organizations determine exactly how many team members they’ll need to meet projected customer demand — without wasting resources on unnecessary labor.
It involves analyzing historical trends, gauging upcoming events or product releases, and using these insights to predict future staffing requirements. The goal is to maintain a balance: too few employees hurts service quality; too many drives up labor costs.
Workforce forecasting is the process of predicting how many employees — along with the skills they possess — will be needed to manage future workloads. Businesses look at trends in historical data, upcoming sales or marketing efforts, and external factors like seasonality to create staffing models that minimize both service bottlenecks and unnecessary labor costs.
Assembled makes forecasting seamless by analyzing historical contact volume trends, layering in real-time queue insights, and projecting out email backlog, for a truly dynamic staffing engine. Instead of using static models that fail to capture business fluctuations, Assembled continuously refines forecasts based on live data, ensuring teams have the right staffing levels at all times.
Workforce managers can factor in monthly or annual seasonal patterns, marketing campaigns, or unexpected outages directly within the platform — without relying on spreadsheets or manual workarounds. Live insights across every channel empower managers to proactively adjust schedules before any issues arise, maintaining service levels without overspending on unnecessary headcount.
Employers who use workforce forecasting enjoy more than just an optimized headcount. They also gain a competitive advantage by aligning labor with business objectives, cutting unnecessary costs, and improving customer experiences. Here are four primary benefits to consider:
Overstaffing increases labor costs, while understaffing leads to overtime expenses, SLA breaches, and customer dissatisfaction. A well-structured forecast allows teams to align staffing with projected demand, preventing both unnecessary payroll costs and last-minute scheduling crises.
How forecasting helps:
Poor forecasting leads to longer wait times, ticket backlogs, and inconsistent service experiences, damaging customer trust. When teams accurately predict workload, they can maintain response times, meet SLAs, and improve overall customer satisfaction.
How forecasting helps:
Instead of waiting for a crisis to determine staffing needs, leaders can predict peaks and plan accordingly. This shift enhances long-term workforce planning while allowing for real-time adjustments in response to sudden surges or market fluctuations.
How forecasting helps:
When employees constantly scramble to cover gaps, frustration and burnout can set in. Conversely, overstaffing can lead to idle time and a lack of challenge. Balancing workloads with data-driven forecasts promotes a healthier work environment and ultimately improves retention.
How forecasting helps:
When it comes to channel forecasting, there’s a big difference in how teams plan for live versus asynchronous channels. Most workforce management tools treat email forecasting like chat or phone support — only accounting for incoming volume.
Assembled was purpose-built for teams that run support on all channels, email included. Our forecasts factor in email-specific features like backlog accumulation and longer-term SLA targets. This means teams can staff not just for today’s new cases, but also for unresolved tickets from previous days. This ensures that SLAs on live channels don’t suffer due to lingering email backlogs.
Typeform, for instance, was able to increase forecast accuracy to more than 90%, and eliminate the need for daily manual forecast adjustments.
Even the most advanced data models can fall short without the right processes and mindset. Below are several best practices that help maintain accuracy and agility in workforce forecasting.
Consolidating key metrics — from historical scheduling records to customer engagement stats — ensures a single source of truth. This reduces data silos and makes it easier to spot trends across different teams or channels.
Assembled’s integrations with Zendesk, Salesforce, Gladly, and Intercom pull historical contact volume and real-time agent state data into one unified dashboard. We’ll generate a staffing plan that can accommodate expected volume while remaining agile enough to adapt as conditions change.
Instead of relying on static reports or manual spreadsheet exports, Assembled continuously updates forecasts based on real-time ticket volume, email backlog, and agent availability, ensuring that staffing plans reflect actual demand as it shifts. This seamless data flow eliminates the need to switch between platforms or manually reconcile information, reducing errors and saving teams hours of manual effort each week.
Market conditions and consumer behavior can shift abruptly. Building in contingency plans like on-call staff or flexible shift structures prevents last-minute scrambles.
Accurate forecasting should include input from finance, operations, and frontline teams. Finance provides budget constraints, operations projects output, and the frontline offers practical insights into day-to-day needs.
Historical data is foundational, but it only shows where you’ve been. Leading indicators such as upcoming product launches or planned marketing campaigns offer predictive insights that refine forecasts before demand changes become obvious.
Even a well-built forecast requires periodic tuning. Evaluate accuracy against actual outcomes — if forecasts are consistently off, dig into why. Do you need more accurate data? Are you missing certain variables?
Effective workforce forecasting relies on different mathematical methods to predict future staffing needs based on historical data, trends, and external factors. These methods fall into four broad categories:
Assembled applies these forecasting methods through four distinct models, allowing teams to select the approach that best fits their specific workload and operational requirements.
Whether your team has steady demand, seasonal peaks, or unpredictable surges, Assembled’s models help optimize staffing by analyzing historical trends, adjusting for real-time changes, and allowing teams to compare forecast accuracy over time.
Below, we outline each model, who it’s best for, and some additional considerations for evaluating whether the model is best suited for your needs.
This model calculates the average ticket volume over a set number of weeks and uses that baseline to project future staffing needs. It works best for teams with relatively stable demand patterns and minimal short-term fluctuations.
Assembled gives teams full control over their forecasting cadence with configurable N-week averages, allowing them to fine-tune look-back periods — whether it's a 4-week view for short-term agility or an 8-week average for more stable demand patterns. By tailoring forecasts to match operational rhythms, teams can reduce variability and improve staffing accuracy.
This model builds on the N-week average but adjusts for recent trends, ensuring that forecasts are not entirely backward-looking. It helps teams account for recent increases or declines in ticket volume when staffing for upcoming weeks.
Assembled’s N-week average with momentum model automatically detects trends by applying a line of best fit to past data, giving more weight to recent shifts in volume. It adjusts forecasts based on interval-level patterns, ensuring staffing keeps pace with gradual increases or declines. For example, if a 9 a.m. Monday interval typically sees 20% higher volume than average, Assembled adjusts the forecast accordingly.
This model is designed for teams that experience clear seasonal fluctuations in workload. It analyzes year-over-year trends to anticipate spikes and lulls, making it ideal for businesses with holiday rushes, annual sales events, or cyclical support patterns.
Assembled’s seasonal forecasting model predicts volume fluctuations by analyzing over a year of historical data, making it ideal for teams with recurring surges like holiday sales, monthly subscriptions, or tax season. It detects weekly, daily, and interval-level trends, automatically adjusting forecasts based on long-term growth. This ensures teams prepare for spikes in advance, avoiding last-minute staffing changes.
The model is also highly customizable, allowing teams to fine-tune forecasts for unique operational patterns, including non-traditional cycles that don’t follow a standard 7-day cadence.
The Prophet Model (based on Facebook’s Prophet algorithm) is the most advanced forecasting option in Assembled. It combines seasonality, historical trends, and external factors to create adaptive, long-term workforce forecasts.
Assembled’s Prophet model uses machine learning to forecast long-term trends, automatically detecting seasonality, growth patterns, and external events like holidays or product launches. Built on Meta’s Prophet library, it dynamically adjusts forecasts to keep staffing aligned with demand. Ideal for teams managing multiple seasonal cycles or growth shifts, this model prioritizes accuracy over explainability, making it a powerful choice for organizations needing data-driven, adaptable forecasting.
Moving from theory to practice involves more than installing new software. It requires buy-in across departments, a clear plan for data management, and ongoing commitment to iterative improvement. Below is a recommended roadmap:
A structured rollout ensures that workforce forecasting becomes a living process rather than a one-time initiative. Over time, feedback loops and continuous improvements will keep forecasts sharp, reducing both staffing inefficiencies and unexpected labor costs.
Gather and clean your data
Accurate forecasting starts with centralized, real-time data. Assembled integrates with help desk tools like Salesforce, Zendesk, and more, eliminating manual errors by pulling accurate live data. By centralizing data, for example, a team managing both in-house and outsourced support can track volume trends across all vendors at once for better staffing. With native data validation, Assembled ensures that all your ticket mapping is accurate before going live.
Select and configure tools
The Assembled Forecast Management tool allows you to see the accuracy of all forecast models in one easy comparison table. This means you’ll be able to see the results of our accuracy reporting before you commit to a model. You can also swap between models at any time.
