Benjamin Franklin enjoyed this old proverb: “A little neglect may breed mischief. For want of a nail, the shoe was lost. For want of a shoe the horse was lost, and for want of a horse the rider was lost.” The message can be easily ignored, that seemingly unimportant factors have dramatic knock-on effects, and omitting them entirely invites grave consequences. Here, Sean Robinson, service leader at industrial automation expert Novotek UK & Ireland, explains how a little forethought and investment can sidestep imposing future problems.
Sadly, the famous proverb ends with the battle being lost, for want of a rider. While military equipment logistics might be somewhat beyond our remit here at Novotek, this analogy has deafening parallels with many industries.
Instead of losing battles, however, industries face unplanned downtime. A recent study from ServiceMax shows that a staggering 369 of the 450 companies surveyed, over 80%, had suffered unplanned downtime within the three years in question.
There are many ways that unplanned downtime can negatively impact a business. In continuous process industries — which range from butchery and water treatment to steelmaking — downtime causes produce to be lost. The costs of this further impact the bottom line, beyond just lost profits.
When producing less process-sensitive products, the negatives are still profound. Imagine if one of your upstream suppliers has experienced an unplanned fault, and your business depends on their supply. How long would your company put up with it? The tighter logistical times get, the more of an issue it becomes — particularly in cases of just-in-time production.
This is a major concern that’s shared by a large portion of businesses. More than half feared they would lose their customers’ trust if they were to suffer a high-profile incident. One-in-ten said that such a failure would be unrecoverable, and ultimately spell the end for their business.
Preventing poor performance
Another military analogy comes to mind, here. Specifically, the old British army saying known as the six Ps: prior planning and preparation prevents poor performance.
Preparation in these contexts refers to investments in, and the thorough integration of, supporting oversight software, but also in ongoing technical support of that software.
One approach is to work with the concept of the digital twin. These systems emulate physical processes in software, meaning failure modes can be safely simulated, processes can be tested against changes in products or ingredients and even entire line redesigns can be simulated, all without having to make any material changes.
However, as with most things in industry, these schemes must be well supported, otherwise they can easily cause trouble. Just as unmanaged physical equipment can lead to inefficiencies and failures creeping in through malfunction and wear, implementing incorrect decisions derived from poorly managed digital twin software can be equally detrimental.
Make maintenance a sure thing
This is a pervasive, perennial issue that technology-reliant businesses face: The mismatch in perceived values between active equipment, the infrastructure supporting it and lifetime technical support.
An upgrade to faster lineside robotics, for example, is easy for budgeters to rationalise because the [...]
