Companies Should Strive to Achieve A “Reliable State”

In today’s rapidly evolving and increasingly competitive global economy, companies are under tremendous pressure to function at the peak of performance, and do so cost-effectively. But with so many initiatives and programs that comprise the daily operations of an organization competing for limited time and resources, it can be difficult for companies to know where to focus their attention.
While those initiatives that companies consider a priority will vary depending upon the organization’s unique business situation and industry sector, one area that most companies in the manufacturing industry would be wise to focus on is the convergence of safety, reliability and productivity that enables the achievement of a “reliable state.”
A “reliable state” is the point at which a company’s safety, reliability and productivity are optimal. As a result, organizations are able to realize increased performance, efficiency and profitability. As the term suggests, reliable operations are the keystone to achieving optimum safety and productivity.
With respect to safety, generally speaking, the more reactive or corrective maintenance that a company must perform to repair equipment and components, the greater the risk of injury to workers as this type of maintenance can be more unpredictable and hazardous than preventive maintenance. Increasing the reliability of equipment by appropriate use of precision, predictive and planned maintenance keeps unscheduled repairs at a minimum and leads to a decrease in safety incidents and injuries.
Similarly, when reactive or corrective maintenance needs to be performed to repair equipment or components, those assets are generally out of operation for a longer period of time than for preventive maintenance. Improving the reliability of equipment reduces the need for mechanical interventions (transient conditions), and keeps those assets operating at longer intervals, which in turn increases productivity.
But what steps can companies take to keep their maintenance and reliability program functioning at its peak so they can achieve a “reliable state” of heightened reliability, safety and productivity?
First and foremost, achieving a “reliable state” must be a collective goal of the entire organization, both company leadership and employees. Often this involves changing how the concept of reliability is perceived. Employees sometimes have the misperception that productivity gains achieved through reliability programs are actually intended, primarily, to downsize personnel within the company. That is why it is important for employees to realize that improving the reliability of equipment within their area of control is about creating a safer working environment for them and other employees – it is about protecting them.
It is also important that company executives make clear their commitment to improving reliability to all employees. This includes not only demonstrating their commitment by dedicating the necessary financial resources, but also by conveying it through face-to-face communication with workers on the shop floor in a tone that is supportive of employees’ efforts.
Once all employees in the company are “bought-in” to achieving a “reliable state,” processes and practices must be effectively executed to reach and sustain that goal. Doing so requires work to be executed with operational discipline. DuPont Sustainable Solutions (DSS) defines operational discipline as “the deeply rooted dedication and commitment by every member of the organization to carry out each task the right way every time.”
Simply put, operational discipline means complying with a set of well thought out and well-defined processes, and consistently executing them correctly. Operational discipline provides a structured way to accomplish tasks through a fundamental set of procedures that are specific to a business’s unique products or service offerings. It improves the execution and performance of the work across an organization to a point where leaders and employees consistently and continuously address the day-to- day operational needs of the business in a timely and safe manner.
When companies employ operational discipline, certain tasks reach higher levels of efficiency, contributing to fewer mistakes and better quality. As a result, time and opportunities open up for everyone to focus on elevating performance and results. There is a ripple effect of benefits, each having the power to unleash rapid and continuous improvement. Regardless of the industry, operational discipline increases reliability, decreases the risk of a high-consequence incident occurring, and contributes to increased productivity.
One way to ensure operational discipline is for companies to focus keenly on addressing leading indicators in their maintenance and reliability programs. Leading indicators, if not recognized and acted upon, will result in an actual failure or event, which is a lagging indicator. They can include incident near- misses and unsafe conditions, or early function failure in equipment. A simple example can be rust.
Rust on a component is a leading indicator of corrosion and loss of mechanical integrity, and if it is not addressed immediately through a preventive maintenance action (for example, removing the rust and repainting the component) it could lead to a lagging indicator. In this case, the lagging indicator could be a hole in the component, which leads to loss of containment of hazardous materials.
The human tendency is inclined toward addressing lagging indicators because they require immediate attention. In some cases, though, lagging indicators can be as severe as a major incident that requires shutting down equipment for an extended period of time, or even a fatality. Clearly, striving to address leading indicators through good operational discipline is one of the best ways for companies to increase reliability, safety and production.
But sustaining operational discipline across an organization is no easy task. Companies need to adopt an integrated approach (see Figure 1 on PDF) to their business processes if improved operations are to be effectively and efficiently implemented on a consistent basis. An integrated approach links critical elements, including:
This integrated approach promotes the operational discipline required for companies to achieve a “reliable state.”
Optimizing a company’s reliability, safety and productivity can seem a daunting task, particularly given the many competing priorities faced by organizations. But by thinking of them as interdependent priorities, and pursuing them through business processes that are fully integrated, the goal of the “reliable state” is attainable.
