Best practices for calculating remaining (food) manufacturing capacity?

March 04, 2025

I'm evaluating a manufacturing business and would like to understand how much capacity remains before making an offer. Does anyone have experience in this and would be willing to share their insights?

Evaluating remaining food manufacturing capacity is crucial for assessing scalability and potential bottlenecks. Here’s a structured approach based on best practices: 1. Define Key Capacity Metrics To determine remaining capacity, first establish the key metrics: Production Line Capacity (units per hour or pounds per shift) Batch Processing Capacity (batch size and cycle time) Shift Utilization (current shifts vs. maximum possible) Equipment Utilization (OEE – Overall Equipment Effectiveness) Facility Constraints (storage, refrigeration, space availability) 2. Calculate Current Utilization Assess the actual production levels relative to maximum capacity: Utilization Rate = ( Actual Output Maximum Theoretical Output ) × 100 Utilization Rate=( Maximum Theoretical Output Actual Output )×100 For example, if a line can produce 1,000 units per hour but is running at 750 units per hour, its utilization is 75%, leaving 25% headroom. 3. Identify Constraints Even if machinery has additional capacity, other factors can limit output: Labor Availability: Can more shifts be added? Ingredient Supply: Are raw materials scalable at higher volumes? Storage & Logistics: Can warehousing and distribution handle more inventory? Regulatory Compliance: Are there permitting or food safety constraints? 4. Conduct a Bottleneck Analysis A bottleneck in a single stage (e.g., packaging, cooking, cooling) can limit the entire line’s output. Use tools like: Theory of Constraints (TOC): Identify and alleviate the slowest process. OEE Analysis: Break down availability, performance, and quality losses. 5. Evaluate Expansion Scenarios Incremental Capacity Gains: Can minor tweaks (e.g., shift extensions, automation) increase output? CapEx Investment: What would be required to scale production (e.g., adding a second line, upgrading ovens)? Seasonality Factors: Is peak season utilization already near full capacity? 6. Run Sensitivity Analysis for Growth Model different demand scenarios and assess how quickly the facility reaches full capacity. For example: 10% increase in demand: Can the current setup absorb it? 20-30% growth: Would new equipment or additional shifts be required? 7. Validate Data with Site Visits & Interviews Numbers from financials might not reflect actual constraints. Speak with: Production managers (real-world bottlenecks) Shift supervisors (downtime, inefficiencies) Supply chain teams (raw material sourcing challenges) Would you like help structuring a simple model for capacity calculations?

Hi Scott, congratulations on finding an acquisition candidate. If you proceed, and you need engineering or manufacturing support I am based in Wichita, KS a manufacturing regional hub. Happy to help make intros.

To answer your question. Two approaches I would propose:

1. From historicals, what was there peak production. If demand was the constraint, you may have capacity beyond this peak. If however, the limiting factor was company related, that goes into the second approach of understanding production bottlenecks/constraints.

2. If I were to work to find the bottlenecks in their production process, I would ask what part of the production process is always the busiest? This should be the first bottleneck, then ask for the next busiest, and so on. They are busy because they are slow and a bottleneck. If you can relieve whatever the constraint is, then you will have more production capacity. Eventually, if you have a really effective manufacturing operation, the constraint will be consistent and reliable demand. Then the game will be to get consistent and reliable demand for your highest margin products.

There is an amazing book I would recommend that goes into operation efficiency in an entertaining way called "The Goal" by Eliyahu M. Goldratt which has informed a lot of my thinking about manufacturing as well as building effective processes.

Cheers to your success!
