In the past, agility was a luxury for food and beverage manufacturers. Today, it is table stakes for manufacturers as increasing product variety, shorter runs, and constant change continue to exert pressure and drive complexity.
Hidden inside this tangled web, unbeknownst to many companies, lies one of the most powerful, underused levers of profitability – the changeover.
Changeovers can quietly absorb 20% to 40% of available production time, draining hours each week into set up, cleaning, verification, and paperwork. Instead of treating this as an unavoidable cost of doing business, leading companies are converting changeovers into fast, repeatable, high-value capabilities that unlock new capacity and margin. The question is no longer whether you can afford to improve changeovers, but how quickly you can.
The True Cost of Changeovers
From the outside, changeovers can appear straightforward. Stop the line, clean it, reconfigure, restart. Inside the plant, they resemble a NASCAR pit stop: a tight, choreographed sequence where delays, miscommunication, or missing materials quickly turn into wasted time and lost throughput. A single changeover might involve dozens of manual and mechanical tasks, each introducing the risk of waiting, rework, or scrap.
But the true cost goes beyond the clock. Prolonged changeovers take a toll on manufacturers in several ways, including by:
- Tying up skilled operators in non-value-added work
- Increasing labour and overtime costs
- Triggering missed delivery windows and schedule instability
- Sapping morale as teams repeatedly scramble under high pressure
When margins are already razor-thin, losing even an hour to inefficient changeovers can compound into significant annual losses across multiple lines. Just as importantly, slow, unpredictable changeovers make organisations more cautious. Teams hesitate to test new SKUs, formats, or promotional runs because they fear disruption more than they value the opportunity. That is where competitive advantage starts to slip away.
The Need for Speed
Consumer expectations for both variety and immediacy continue to climb. Product portfolios expand, batch sizes shrink, and the ratio of productive time to changeover time keeps narrowing. In this environment, speed is not a nice-to-have metric; it is a direct proxy for competitiveness.
Speed amplifies agility. Plants that can pivot on a dime when recipes, packaging, materials, or other regulatory requirements change are the ones that are able to maintain their service quality levels while others pause to get reoriented. Rapid, reliable changeovers give companies the confidence to pursue seasonal offers, limited-time runs, or customer-specific variants without worrying that their entire operations will grind to a halt. Companies can make changeovers faster – in some cases 30 minutes instead of several hours – by increasing their capacity to run more SKUs on the same products, and scaling back on finished-goods inventory without increasing stockouts.
Real Results from the Field
Here’s a closer look at how one company – one of the largest privately held retail grocers – managed a large, complex, end-to-end process that was slowing down multiple stations. The company’s internal Lean team had flagged concerning productivity dips, especially at one key main site that served most of its stores. The grocer needed to increase its speed and productivity, and keep quality at a high bar, and it needed to do it quickly.
In looking more closely at the most problematic changeovers, each of the site’s operating stations required modification before every SKU, and the ingredients and components involved were highly varied. It was an intricate web, with success dependent on getting all materials staged correctly and on time. Working together with the company’s leaders, we began by defining standard work categorised into two categories:
- External activities – tasks that can be done while the line is operating
- Internal activities – tasks that must be done when the line is stopped
One subtle but important change, for example, was having one worker focus on replenishing production materials while the other prepped both sides of the line for the next run. The site’s required allergen/sanitation process was also optimised. Within just four months, the grocer achieved major gains across the board, including:
- Major cost savings due to improved packaging productivity
- Significant cuts in downtime and idle time due to assembly being optimised to takt time
- Reduced startup times of 53% and 6%, respectively, due to standard work and faster changeovers
- A 75% reduction in label approval time due to streamlining the label verification and quality control processes
Take Control of Your Changeovers
We have seen firsthand that changeovers are not occasional efficiency levers; they are one of the clearest fault lines between high performers and everyone else. When changeover time is significantly reduced, plants consistently make more products, improve quality and reduce errors, sustain their service levels, and boost employee morale. On the other hand, every hour, day, month, and year you wait to improve, your competitors are passing you by. The time has come to turn your changeovers into an edge.
