You work hard on your safety & health/EHS program at work. You give it a lot of thought, you spend a lot of time on it, and you care a lot about it (and about the people and environment it’s intended to protect).
But how do you know if what you’re doing is effective? How do you know if it’s working? How can you measure your own performance?
One thing you can do is to keep track of the number of incidents at work. Things like work-related fatalities, injuries, or illnesses. Or chemical spills to the environment. As a group, these are known as lagging indicators. They’re called lagging because they tell you about things that have already happened.
Lagging indicators have their place, and they’re important to track. But they have their limits, too, and it’s helpful to track other stuff as well in order to truly measure the success of your EHS program.
As you may have guessed, we’re “leading up to” the subject of leading indicators here, and the use of leading indicators for EHS measurement. Ha! Did you get the little joke? 🙂
But jokes aside, what are leading indicators, in general? What are some good examples? What’s the point of using them? How can you get started using them? Those are the kind of questions we’re going to address below.
Using Safety Leading Indicators for Safety Measurement
Let’s start by giving some general information:
- What a leading indicator is
- What an safety leading indicator is (and/or EHS leading indicators)
- Why you should monitor safety leading indicators
- Some types and examples of safety leading indicators
What Is a Leading Indicator?
A leading indicator is something that gives you an idea if something else will or might happen in the future. A leading indicator is not a guarantee that something will happen in the future. But as the name implies, they indicate or suggest an increased chance that the future event may occur.
For example, you commonly hear leading indicators discussed when people are talking about the national economy on the news. These economic leading indicators give us a way to anticipate or predict what the national economy as a whole might do in the future. And maybe even a chance to take action and change the odds (and the future).
Some examples of economic leading indicators include manufacturing activity, retail sales, building permits, the housing market, and new business start ups. You can see how analyzing these leading indicators can help you predict if the national economy will grow, slow, or even contract in the future. And that’s one of the primary benefits of leading indicators–they help you anticipate and predict.
And another benefit is that they let you take action and make changes that might affect the future. For example, if leading economic indicators are slowing, suggesting that the national economy may go into recession, the government may choose to react by increasing government spending or reducing taxes, with the goal being to avoid that recession.
What Is a Safety Leading Indicator?
Now that we know what a leading indicator is in general, let’s turn our attention to what a leading indicator is in terms of safety or EHS.
According to the National Safety Council (and their Campbell Institute), EHS leading indicators are:
“…proactive, preventative, and predictive measures that monitor and provide current information about the effective performance, activities, and processes of an EHS management system that drive the identification and elimination or control of risks in the workplace that can cause incidents and injuries.” (1)
So at the most fundamental level, a safety leading indicator is a predictive tool you can use to identify and then eliminate or control risks that might otherwise lead to incidents and injuries. Note that the two key aspects are the predictive capability and the ability to use the information to act and then change the odds.
What Are Some Characteristics of Good Leading Indicators?
That definition above gave you some good insight into what an EHS leading indicator is, but let’s look at this more closely.
There are many things you can measure at work (we call these metrics). Some of these are things you can choose to use as safety leading indicators. We’ve already said that the metrics you choose to use as leading indicators should have a predictive power that helps you eliminate or control risks and thereby reduce incidents.
So, the metrics you choose as leading indicators for safety should be:
- Achievable–this means you really can measure them accurately
- Transparent–this means the metric and how you measure it should be something everyone can clearly understand
- Meaningful–this means you’re measuring a real thing at work and it really has predictive powers to help you eliminate or control risks
- Actionable-this means you can measure then and then take action to change them if necessary
- Easy to communicate–this means they must be easy enough to communicate to workers, peers, and company bosses/executives
- Timely–this means you can gather and evaluate recent data so it reflects current or recent conditions and that you can do it quickly enough so that it would allow you to eliminate and/or control risks (2)
When you select the measures you want to use for your own safety leading indicators, keep these tests in mind. If you’ve selected a metric to act as a leadin gindicator that you’ll measure, it should stand up to the tests above.
Is It Important to Measure and Monitor Safety Leading Indicators? What Experts Say
If leading experts in the field told you it was important to track EHS leading indicators, would that be enough for you to do it?
Because according to a study published by the National Safety Council that surveyed industry members, it’s important. Check the graph below. (3)
Sixty-one percent of the companies surveyed said the use of EHS leading indicators was “extremely important” and another twenty-eight percent said “very important.” That’s an impressive combined total of eighty-nine percent who give a LOT of importance to the use of EHS leading indicators.
Even the other companies say it’s “moderately important” or “slightly important.”
Admission-I’m not really sure what it means to be “slightly important,” but I guess it means it’s still important. Apparently “not at all important” was an option and nobody selected that.
Reasons to Measure and Monitor Safety Leading Indicators
But maybe you’re not the kind to do something just because experts say it’s a good thing to do. Maybe you need some reasons and some convincing. Well, that’s a good thing, and we’ve got some reasons for you below.
The primary reason to use EHS leading indicators is because they give you a chance to prevent a problem before it happens.
To put that another way:
“…leading indicators are designed to give advanced warning of potential problems so that preventive actions can be taken. Additionally, they help to reveal the weaknesses in an organizations’ procedures or employee behavior before they have a chance to cause real harm.” (3)
That seems like reason enough. What’s not to like about doing something that will help you prevent a problem?
But that’s not all that measuring and monitoring EHS leading indicators can do for you (and your company). In addition, monitoring EHS leading indicators allows you to:
- Evaluate the performance of your EHS program
- Strengthen your safety culture
- Contribute to the continuous improvement effort for EHS
- Communicate results of your EHS efforts to others at work (4)
So all told, the use of EHS leading indicators is recommended for the reasons listed below.
Types of EHS Leading Indicators
There are lots of different metrics that can be used as leading indicators for safety and/or EHS.
These include things like:
- Observations of safe or unsafe behaviors
- Near miss reports
- Safety training
- EHS-related meetings held
- Regulatory violations, citations, and penalties
- Incidents (injuries/illnesses/environmental problems/property damage)
- Incident investigations
- Employee safety suggestions received
- Employee safety suggestions acted on
There’s no single “master list” of EHS leading indicators that every company uses or that would work well for every company. Instead, each company should select metrics that work best as leading indicators for their own needs and circumstances.
To help you come up with your own list, you can think of EHS leading indicators as falling into one of three categories.
These include behavior-based, operations-based, and systems-based indicators, as shown below.
Here they are explained in a little more detail:
- Behavior-based EHS indicators are related to the actions of individuals or of groups of people. Examples might include safety walkarounds by EHS personnel, on-the-job safety observations by employees, and the ratio of positive to negative safety observations.
- Operations-based EHS indicators are related to the function of a company’s machinery, equipment, operations, and infrastructure. Examples might include the number of new trainings for operators, the number of regulatory inspections without findings, or the number of defects found in equipment.
- Systems-based EHS indicators are related to the company’s EHS management system. Examples might include the number of reported near-misses, the number of completed safety/EHS trainings, the number of corrective actions, and the number of safety inspections and audits. (5)
When coming up with your own EHS leading indicators, it may help you to start by thinking of these three categories and make sure you select some indicators to measure performance in each category.
Can You Give Me More EHS Leading Indicators?
The National Safety Council (and their Campbell Institute) has created several great guides on the use of EHS leading indicators. One of them, titled Practical Guide to Leading Indicators: Metrics, Case Studies & Strategies, includes a very long list of metrics that might be helpful as leading indicators for your company to measure. Click this link, download the guide (it’s a PDF), and check out the list on pages 14-18. They include a large number of specific metrics in each of the following categories:
- Risk assessment
- Hazard identification/recognition
- Risk profiling
- Preventive and corrective actions
- Management of change processes
- Learning systems
- EHS management systems
- Recognition, disciplinary, and reinforcement program
- Leading indicator component evaluation
- Communication of safety
- Safety perception survey
- Prevention through design
- Leadership engagement
- Employee engagement and participation
- Area observations/walkarounds
- Off-the-job safety
- Permit-to-work systems
- Equipment and preventive maintenance (6)
On the other hand, if the list above is enough to get you started or pointed in the right direction, great.
Let’s Talk More About Near Misses
Near misses are an interesting issue within the discussion of lagging and leading indicators for EHS.
Interesting and controversial, that is. Because there are people in (at least) two camps about whether or not they’re leading indicators and/or whether or not they should be used that way.
The Argument FOR Using Reported Near Misses as Leading Indicators
The report of a near miss, followed up by corrective action, may help prevent a “real” incident from occurring in the short- or long-term future.
As a result, some believe near misses are an effective EHS leading indicator that might be useful to measure.
The Argument AGAINST Using Reported Near Misses as Leading Indicators
An increase in reported near misses may mean there are more hazards in a workplace. But on the other hand, it might just be that people are being more observant, or that they feel more free to report near misses (without negative personal consequences–like being blamed by their boss). Or maybe they feel reporting a near miss is more likely to lead to a positive corrective action.
Because the reasons behind near miss reporting can get murky like this, some suggest that near misses are not an effective EHS leading indicator and they recommend against using near misses that way.
A Possible Compromise On Near Misses: Lagging or Leading, Depending on Circumstances
The National Safety Council/Campbell Institute’s Elevating EHS Leading Indicators: From Defining to Designing has this to say about near misses:
“The issue of near misses remains an ongoing debate in the world of occupational safety and health with each side possessing valid arguments. One answer that straddles these two opinions is that near misses an be considered both leading and lagging depending on how they are treated. If the intent is to treat near misses as actual incidents, especially when it comes to mandatory reporting, the near miss itself can be seen as an event with negative consequences and considered more of a lagging indicator. If the intent of tracking near misses is to find weaknesses in a safety management system and improve organization safety performance, then near misses become more leading in nature.” (7)
This seems reasonable to me, but of course you can make your own decision.
One final interesting thing about near misses: although we just discussed if they should be considered leading or lagging indicators, there’s another controversy about the name itself. Many people call these near misses, but others prefer to use near hits for this same idea. Watch for a future article from us on this topic.
Using Lagging AND Leading Indicators
We’re focusing on leading indicators in this article. So much so, you might get the idea that there’s no reason to track lagging indicators. But that’s not our intention. Let’s turn our attention to lagging indicators briefly.
Don’t Forget Your Safety Lagging Indicators
Traditionally, some companies have focused solely or too much on lagging indicators such as injuries and illnesses.
And there are some problems with that. For one thing, at many companies, the injury and incident rates (these are lagging indicators) are already quite low. It’s difficult to get them down further, so tracking just lagging indicators doesn’t give much information about the performance of the EHS program.
Secondly, if you’ve got a low incident rate and even a minor incident or a small number of incidents do occur, the changed rate may make the EHS performance look much worse than it really is.
And finally, focusing solely on lagging indicators can create give people an incentive to “game” the system. If you’re sole focus is on lagging indicators, and people’s future employment, promotions, raises, and performance bonuses are at stake, what happens when there’s a recordable incident? Isn’t there the possibility that people won’t actually record it? You bet there is.
So those are a few of the issues of tracking only lagging indicators or giving too much emphasis to them.
But we don’t want you to throw out the baby with the bathwater. Just because you should increase your focus on leading indicators doesn’t mean you should quit measuring lagging indicators.
Experts Tip: Track Both Leading and Lagging Indicators
The best practice is to track some lagging and some leading indicators. That’s not how it works at all sites and organizations, as you’ll soon see. But it’s a good practice.
Here a breakdown of the percentage of companies tracking lagging indicators, leading indicators, or both at the site-level. (8)
And here’s a breakdown from the same companies, showing if they’re tracking lagging indicators, leading indicators, or both at the corporate level. Note that there ratios are different than those at the site-level above, and that nobody reported using only leading indicators at the corporate level. (9)
The “blend” of lagging and leading indicators that you use at your company will be up to your company. Likewise, it will be up to your company if you use the same blend at the site level that you use at the corporate level, if each site has the same or different measures, and how (or if) you “roll up” the indicators at the department/site/region or district/corporate level.
Expert Tip 2: Link Leading Indicators to Changes in Lagging Indicators
Remember that a safety leading indicator is supposed to have predictive powers.
Meaning, if you’re tracking EHS leading indicators, you should be able to use your data to accurately predict what your EHS lagging indicators will do. So, if your EHS leading indicators are trending in a positive direction, then your lagging indicators should also trend in a positive direction.
This ability to be able to “link” or connect the performance of your leading indicators with your lagging indicators is important.
Here’s now the National Safety Council (and the participants of a survey they developed) puts it:
“The vast majority of respondents stated that having the ability to tie changes in leading indicators to stronger or weaker performance on injury rates and other lagging indicators is very important (64%) or extremely important (21%).
In a follow-up question, survey respondents were asked if they were able to establish a statistical relationship between leading and lagging indicators and, if so, how they were able to do so. Six out of thirteen respondents (46%) were able to definitely state that they have found a statistical link between leading and lagging indicators…The methods used by organizations to measure this relationship was limited to finding a general trend or a temporary association between leading and lagging metrics (e.g., sites with higher volume of near miss reporting or fewer behavior-based safety observations have lower injury rates.)” (11)
So according to the NSC and their survey:
- It’s important to try to link leading and lagging indicators
- It’s possible to link them
- Common linking methods include general trends or temporary associations
The NSC/Campbell Institute document titled Practical Guide to Leading Indicators: Metrics, Case Studies & Strategies includes several case studies that show organizations like Cummins, Honeywell, NASA, USG, and Fluor doing just that. It’s worth checking out if you’re interested in more details.
Working with Safety Leading Indicators at Your Company
We’re going to stop here, but there’s still more to be said about leading indicators for EHS performance. Notably, how to begin doing it–which ones to select, and how to manage and refine what you’re doing over time.
We anticipate writing another article that covers some of those issues in the future. But we also welcome any of your comments in the section below. Especially from people who have experience and (presumably) success doing this.
Until then, thanks for reading. We’ll catch you next time. Let us know if we can help you with safety training management software, safety training online courses, and/or custom safety training materials.
