How do we balance time and money when it comes to plant maintenance? It’s common for many organizations to rely upon reactive maintenance, and fixing problems as they occur. While this method can seem cost-effective initially, the costs will increase over time with extended downtime and greater unpredictability. Proactive maintenance, however, while generating a higher upfront cost, can lower overall maintenance costs, reduce equipment and employee downtime, and significantly increase asset availability.
When the COVID-19 pandemic first reached the U.S. in the spring of 2020, it disrupted businesses, forcing many people out of employment. While some employees could work remotely, many roles didn’t accommodate work-from-home arrangements. To cushion its citizens from the hardships of being out of work, the U.S. government established the Coronavirus Aid, Relief, & Economic Security (CARES) Act. This move played a role in shaping the future of work—for many people, the financial benefits extended well into 2021. Stimulus checks and additional unemployment assistance helped many families and individuals in need during shutdowns, but many employers faced labor shortages even after businesses were back up and running.
Since the 1970s, an increasing number of manufacturers have used the three components of availability, performance, and quality to calculate the overall equipment effectiveness (OEE) for determining how well a process is running. OEE is also used to identify areas of improvement. Understandably, most manufacturers target the more prominent areas of concern, which will generate a more dramatic or marked improvement.
Although many manufacturers have implemented overall equipment effectiveness (OEE) over the last few decades, not every facility has embraced it effectively. Often facilities either knowingly or unknowingly neglect or overemphasize one of the three essential components of OEE. Manufacturers apply OEE inconsistently, include too much, or exclude unpleasant data. When used correctly, OEE is an excellent resource for driving continuous improvement in manufacturing facilities. Facilities that are struggling to meet goals or seeking to move up a few extra percentage points can gain the edge they need by returning to basics and evaluating processes honestly.
In the food industry, what you measure tells a story about what you value. You can’t improve what you don’t measure. This sends a strong message from the top that food safety is a priority for the organization. Establishing and communicating objectives and KPIs related to food safety can influence a facility’s food safety culture. But how do you know if your KPIs are driving the right behaviors? And are there better KPIs you could be setting?
Translating Overall Equipment Effectiveness (OEE) into financial terms allows everyone from the plant floor operators to executives, measure continuous improvement and understand the business value of OEE. The challenge is making this a reality. This blog will dive into what it means to measure OEE, why you should translate that into financial terms, why OEE is important, and finally what role software plays.
“An ounce of prevention is worth a pound of cure.” —Benjamin Franklin.
What Is Preventive Maintenance?
Even the best-built equipment will break down over time and need maintenance. Much like taking a car in for regularly scheduled oil changes, preventive maintenance is planned maintenance that a facility performs on its equipment to reduce the risk of failure. Also sometimes referred to as preventative maintenance, the goal is always to incur a lower cost in the present to prevent a higher cost from equipment breakdown in the future.
Many plants are looking for ways to create more efficient processes and develop strategies to better compete with others in the industry. For many, this desire to improve means moving away from traditional manufacturing. It can be a little uncomfortable to look for ways to change when things seem to be working just fine already. However, sticking with processes because “that’s the way we’ve always done them” can work against driving continuous improvement. That’s where implementing OEE comes in.
Manufacturers are seeking ways to remain competitive in challenging markets, and many are exploring how Lean manufacturing and continuous improvement can expand opportunities. There are a number of misconceptions regarding the relationship between the terms Lean manufacturing and continuous improvement. While conflating terms in business and manufacturing is nothing new, it’s crucial to start with some clear explanations of some key general terms to understand better. Manufacturers interested in implementing or expanding Lean tactics can benefit from taking a closer look at these concepts to determine what processes already align with Lean manufacturing and continuous improvement and which do not. For anyone unsure whether Lean manufacturing and continuous improvement are the same thing, keep reading. Let’s start with getting a better handle on what Lean manufacturing is—and what it is not.
While every manufacturer wants to track improvement and meet goals, how different manufacturers approach this can vary drastically. Manufacturers at the enterprise level can quickly devise dozens, even hundreds of performance indicators to monitor every point along every process. Not all of these indicators hold equal importance when it comes to making decisions and driving goals. The adage, "work smarter, not harder," sums up the purpose of KPIs. This blog will separate the wheat from the chaff and dive into KPIs and how manufacturing facilities can effectively use them.
