How Effective are Your Risk Reduction Recipes?

By Kevin McManus, Chief Excellence Officer, Great Systems

Rarely do I come across organizations that do not want to minimize the risk of their operations. At the same time, I consistently come across people who underestimate the types of systemic changes they need to actually realize and sustain such a goal. What practices do your people use daily to help keep risk levels low? How well do these practices actually work? How effective are your recipes for risk reduction?

How Well Do Your Fixes Match the Significance Potential of the Error?

I have seen too many cases in the 430-plus TapRooT® root cause analysis courses I have facilitated where a significant potential incident or actual loss occurs, and yet the proposed corrective actions are weak in nature. For example, I have seen cases where leaders seemingly expect only procedure modifications and safety meeting reminders to keep heavy objects from almost falling on someone in the future.

All too often, I see only one or two relatively weak corrective actions being proposed for what could have been a very serious problem. We do the same thing from a proactive perspective. What types of safeguards do you use to help perform error free work? How effectively are you ‘mixing and matching’ your use of safeguards to optimize human performance? How do you also minimize the risk that comes with potential errors?

The hierarchy of controls model provides a great place to start when one is beginning to create recipes for risk reduction. Consistent, process-driven risk assessments, along with process-based error rate and type analysis, also help calibrate the team to potential risk levels. Most organizations underestimate their current risk levels. This is simply because they underestimate the actual error rates that occur on the job each day.

How Effective are Your Safeguards at Risk Reduction?

When a human error occurs, at least one, and often more than one, safeguard fails. In many cases, people often rely on memory as the only ‘real time’ safeguard. We often use weak safeguards such as policies, low-level engagement training, and supervisory reminders in an attempt to sustain low error rate levels. However, these safeguards rarely achieve their desired rate reduction. As task complexity increases, team chemistry is mixed up, and shifting job scopes occur, the holes in these safeguards become larger and larger.

Reason’s Swiss cheese model also provides guidance for gauging the relative strength of a given set of improvements. In this model, each slice of cheese represents a safeguard. Each safeguard has a probability for success. This is reflected by the relative size of the holes in a given slice of cheese. Theoretically, more slices of cheese equal less risk, as it is harder for the holes to line up and let the hazard get through to the target (or let a defect reach the customer). All too often, we overestimate the power of a given safeguard, however.

If your recipe for risk reduction – your ‘mix of fixes’ – is sound, and your improvements are effective, the likelihood of the errors repeating themselves should be low. This shift alone reduces risk. If the improvements also help reduce the potential severity associated with an error, risk is further decreased. Our common problem here is that we overestimate the relative impact of many of our proposed fixes. One-time meetings to review newly written procedures or to reinforce the rules rarely have a significant behavior change or risk reduction impact.

Different types of work carry different levels of risk with them. Risk of error for a given task also varies with who is performing the work, how frequently the work is performed, and where the work is being performed. That’s why risk assessments prior to work can be very effective safeguards themselves. Consider using an effective risk assessment process to determine the mix of safeguards required to achieve the desired level of risk.

Keep in mind that you will need to ‘mix to taste’ here. You don’t want to invest the effort to prepare a gourmet meal when the goal is to only get the kids fed before the baseball game starts. Too many organizations waste limited resources focusing on weak safeguards. They also often use more layers of protection than they need.

Let’s look at the inspection safeguard, for example. When people perform higher risk work, they may need to use a procedure-driven inspection, complete with step-by-step double sign-offs and photographs. This helps ensure that the risk potential of missing a defect has been reduced. In low risk cases, an undocumented, memory-guided inspection, or no inspection even, may be sufficient.

Creating a Recipe for Risk Reduction

To begin, think about the human behaviors you want to change. What types of errors do you want to help people avoid making? It may be enough to simply clarify expectations with a well-written and well-communicated policy if the tasks are consistent and simple, and staff skills are high. As risk related to potential errors increases, you may want to remove potential memory loss from the ‘what causes errors?’ equation. Require the use of in-hand work instructions to help achieve this goal.

You should never rely on only paper references as safeguards for error free work. At a minimum, commit the tasks to memory via practice-based instruction. Otherwise, refresh memories prior to work with an engaging, focused team huddle. For even higher risk work, consider guarding the target and working to minimize exposure through effective job redesign.

In Summary – Effective Risk Reduction Recipe Action Items

In summary, here are some possible ingredients that you might consider as you develop your own recipes for risk reduction:

  1. Utilize well-designed policies and procedures to define work methods and performance expectations (how time is used and measurable goals).
  2. Minimize the use of memory when performing relatively high-risk work by using well designed, in-hand procedures.
  3. Require all process owners to effectively communicate performance expectations in a daily, positive, and meaningful manner (huddle or tailboard).
  4. Let the potential risk level of the work determine the level of adequacy required. If the potential for error is relatively high, a more in-depth approach to job preparation and the use of in-hand instructions might be useful, for example.
  5. Include adequate time for practice in training – require on-the-job competency demonstration for skills that involve relatively high-risk work.
  6. Engineer out the potential for error whenever possible through effective human factors engineering and organizational ergonomics (job design).
  7. Install a process for capturing key daily errors at the process level, aggregate this data for analysis over time, and address high risk findings with effective fixes.
  8. Use a root cause analysis process, such as TapRooT®, that is designed to consider the impact of missing safeguards and low safeguard effectiveness on the potential for human error.
