Tackling Unforeseen Interruptions: A Guide to Reducing Unplanned Downtime
Every company faces unplanned downtime, a common challenge that disrupts operations and affects productivity. While many associate this term with large-scale industrial processors, manufacturing equipment, or conveyor belts, unplanned downtime can occur in any business setting for a variety of reasons. Though external factors like severe weather impacting power or internet access can contribute, many issues trace back to human involvement. This article tackles unforeseen interruptions and provides a guide to reducing unplanned downtime.
The Roots of Unplanned Downtime
Even with advanced technology, human interaction with assets remains a critical factor in their functionality and longevity. While not always intentional, errors in design, operation, or maintenance often lead to unforeseen stoppages. Understanding these underlying causes proves essential for developing effective prevention strategies.
1. Accidents and Mishaps
Unexpected Incidents Leading to Disruptions
Accidents happen. Human fallibility means we occasionally make mistakes, whether tripping, spilling, cutting incorrectly, or fouling things up. Such incidents can result in unplanned downtime for an asset or an entire company. For example, a local radio station once experienced a complete broadcast interruption after an employee accidentally spilled coffee on the control board. Such mishaps affect not only operations but also pose risks to health and safety.
The only ways to address these occurrences involve heightened situational awareness, minimizing risk—such as keeping liquids at a safe distance from electronics—and diligently adhering to safety warnings and protocols. Proactive measures make a significant difference in preventing these unforeseen interruptions.
2. Equipment Usage Factors
Understanding Wear and Tear
Things naturally wear out over time. Consider clothing: shoes, T-shirts, and jeans all fade, fray at the seams, or thin out with prolonged use. Equipment breakdowns due to usage fall into three main categories:
- General Usage: This covers normal, everyday operation. Over time, equipment ages, and despite preventive maintenance and replacement parts, it eventually breaks down.
- Overuse: Some equipment requires rest periods or planned downtime to function correctly. Continuously running a car engine with the accelerator pressed to the floor quickly leads to problems. Equipment can overheat, lose lubrication, or simply require a pause.
- Under-usage: Paradoxically, some equipment breaks down because it sees insufficient use or does not operate at full capacity. A Formula-1 race car used solely for city driving will not last long. Printer cartridge heads dry out if not used regularly. Automobiles in long-term storage need occasional starting to circulate lubricants. While these examples seem simple, expecting equipment to function perfectly after extended periods of inactivity can result in unplanned downtime.
The solution for all these scenarios is twofold: maintaining vigilance with preventive maintenance schedules and operating equipment within its intended usage parameters.
3. Design Flaws
Built-in Vulnerabilities
Sometimes, the root cause of unplanned downtime traces back to a design flaw. Consider the owner of a new luxury car who experienced excessive tire wear. An investigation revealed a factory defect: an axle misaligned by mere millimeters, causing uneven tire wear. In such cases, breakdowns and unplanned downtime can be delayed, with the cause remaining unknown until a thorough examination occurs.
While human error exists, it often goes unintentional or unrecognized at the design stage. Perhaps the machinery that built the machine had a fault, or something went wrong during the manufacturing process of the product itself. Even small measurement errors can lead to significant problems down the line.
The way to resolve these issues involves investigating abnormalities, contacting the vendor to discuss problems, and ensuring rigorous quality control over equipment that manufactures other equipment.
4. Inadequate Training
Knowledge Gaps and Their Consequences
Proper training plays a crucial role in preventing unplanned downtime. Four areas of training require attention:
- Incomplete Training: A worker may not possess comprehensive knowledge about the equipment, including what to do when something goes wrong. If a part fails and goes unaddressed or neglected, unplanned downtime can occur.
- Lack of Proper Usage Knowledge: Workers sometimes do not receive instruction on the correct and incorrect ways to operate equipment.
- Preventive Maintenance (PM): While a worker may not conduct overall preventive maintenance, they might have responsibilities for smaller tasks, such as reading meters and gauges, frequently refilling fluids, ensuring equipment receives rest periods, and performing proper initialization and shutdown procedures.
The solution here involves obtaining the most comprehensive training available. Workers should proactively seek learning opportunities and ask questions. Those responsible for training must ensure they present necessary and accurate information.
5. Incorrect Programming or Calibration
Precision and Performance
This cause relates closely to design flaws. A minor glitch can seem negligible, but the consistent output of poor-quality products might indicate a machine's fault. More often than not, incorrect programming or calibration stems from human error, perhaps due to insufficient training in the first place. When programming or calibration goes wrong, the machine's operations will be off, and even normal use can lead to breakdowns.
The solution requires constant quality assurance checks, diligent preventive maintenance, and thorough investigation of any abnormal results. Maintaining precision in these areas helps prevent costly interruptions.
6. Improper Equipment Application
Using Tools for Their Intended Purpose
This point stands as quite obvious and directly attributes fault to the operator. Equipment designers create tools for specific tasks. Attempting to use equipment for purposes outside its design parameters risks significant problems. Parts simply cannot handle the stress of being forced to work beyond or outside their intended capacity. For example, using an industrial microwave to bake cookies will undoubtedly lead to issues. The solution remains equally obvious: only use equipment for its designated function.
The Role of a CMMS in Preventing Downtime
Leveraging Technology for Greater Control
A Computerized Maintenance Management System (CMMS) offers a powerful tool for addressing many of the problems leading to unplanned downtime.
- Such a system centralizes maintenance information, making it easier to track equipment history, schedule preventive maintenance tasks, and manage spare parts inventory.
- With a CMMS, companies gain the ability to meticulously plan and execute maintenance activities, reducing the likelihood of breakdowns due to wear and tear or missed service intervals.
- It also provides a clear audit trail for equipment performance, aiding in the investigation of design flaws and identifying patterns of incorrect usage.
- Furthermore, a CMMS can store detailed safety procedures, checklists, and procedures, helping to standardize operations and diminish errors stemming from a lack of knowledge or inconsistent practices.
By providing a structured framework for maintenance and operational data, a CMMS significantly contributes to a more proactive and less reactive approach to asset management.
A Path Forward
Completely eliminating unplanned downtime remains an unrealistic goal. Equipment and other assets inevitably break down, glitch, or cease functioning. However, through comprehensive training, appropriate usage, and consistent preventive maintenance, assets will experience an extended operational life. The focus shifts from elimination to significant reduction. By understanding and addressing these core causes, businesses can create more resilient and efficient operations.
