Understanding Leading and Lagging Indicators: The Foundation of Safety Performance

Toby Graham

For organizations committed to workplace safety, understanding and effectively using both leading and lagging indicators is crucial. These metrics work together to provide a comprehensive view of your safety performance and help predict and prevent future incidents. We recently discussed this topic with our KPA Connect community, and throughout this article, we’ll share insights and real-world examples from safety professionals who are successfully using these indicators to improve their programs. Let’s explore how these indicators form the foundation of a robust safety program.

Defining Leading and Lagging Indicators

Leading Indicators

Leading Indicators are proactive metrics used to predict or influence future results. Think of them as forward-looking measures that help you anticipate and prevent safety issues before they occur. Examples include:

  • Safety training completion rates
  • Workplace inspections and audits
  • Employee safety observations
  • Near-miss reports
  • Preventative maintenance completion

Lagging Indicators

Lagging Indicators are reactive metrics that measure past performance. These indicators tell you what has already happened, such as:

  • Injury rates
  • Workers’ compensation costs
  • Equipment failures
  • Lost workdays
  • OSHA recordable incidents

Hear From Your Peers: Leading & Lagging indicators

Are you using your leading and lagging indicators effectively? Combining both types of indicators can give you a comprehensive view of your program’s performance and help you achieve your EHS goals.

Why Both Types Matter

While it might be tempting to focus solely on leading indicators because they’re proactive, both types play essential roles in a comprehensive safety program. Here’s why:

Lagging indicators serve as your foundation for understanding safety performance. They provide concrete data about what has already occurred in your workplace, allowing you to benchmark your performance against industry standards and maintain proper compliance documentation. Perhaps most importantly, they help you identify systematic issues that might otherwise go unnoticed in day-to-day operations.

Leading indicators, on the other hand, enable you to take a proactive stance on safety. By tracking these forward-looking metrics, you can spot potential issues before they result in incidents. They also provide excellent opportunities for employee engagement, as workers can actively participate in safety observations and near-miss reporting. This participation helps build a prevention-focused culture where everyone plays a role in workplace safety.

Tony Conte highlights this connection:

“By going to leading indicators, workers reporting near misses, they are doing more for safety and lowering incident rates.”
– Tony Conte, EHS Manager, J. Mullen & Sons

This demonstrates how engaging employees in leading indicator activities creates a direct impact on safety outcomes.

Real-World Examples of Leading and Lagging Indicators

To understand how leading and lagging indicators relate to each other in practice, let’s first look at the Safety Pyramid below. This visualization illustrates a fundamental concept in workplace safety: serious injuries and incidents (lagging indicators) are typically preceded by numerous near-misses and unsafe conditions (leading indicators). The pyramid shows that while serious injuries are relatively rare, they are built upon a foundation of more frequent but less severe safety issues. This relationship demonstrates why monitoring both types of indicators is crucial – by addressing issues at the bottom of the pyramid, we can prevent more serious incidents at the top.

Now, let’s examine some specific examples of how these indicators work in practice:

Lagging Indicator Example:
A manufacturing facility experienced seven slip-and-fall injuries in one year. Through investigation, they determined that five of these incidents (71%) were related to poor housekeeping. This lagging data points to a clear, systematic issue that needs addressing.

“Learning from incidents will always be critical for safety professionals, but it just can’t be the only thing you focus on. We have learned several lessons and best practices that have been implemented post-incident. You have to dig in and learn from mistakes. The worst thing you can do is have an incident and keep doing the exact same thing.”
– David Finley, HSE Director at Dolese Bros

Leading Indicator Response:
Based on this data, the facility implements a new housekeeping program where area managers conduct daily walkthroughs using a standardized checklist. They track completion rates and findings as leading indicators, allowing them to address potential hazards before they cause injuries.

How Leading and Lagging Indicators Complement Each Other

Think of leading and lagging indicators as two parts of the same safety story – one tells you what happened, while the other helps you shape what happens next. When used together effectively, they create a powerful cycle of continuous improvement.

The cycle begins with analyzing your lagging indicators, like incident reports and injury data, to understand where problems exist. These insights then inform which leading indicators you should track to prevent similar issues. For example, if your injury data reveals a pattern of incidents during equipment maintenance, you might implement a preventative maintenance program and track completion rates as a leading indicator.

the cycle of leading indicators and lagging indicators

This process follows four key stages:

  1. Analyze Lagging Indicators: Review past performance data to identify trends and areas needing improvement
  2. Implement Leading Indicators: Establish proactive measures and metrics to prevent identified issues
  3. Track Progress: Monitor both types of indicators to measure the effectiveness of your interventions
  4. Adjust Approach: Fine-tune your safety programs based on the data and insights gathered

The key to success is maintaining this continuous cycle – using past performance data to guide future preventive actions while measuring their effectiveness through both types of indicators. Each rotation through the cycle brings you closer to optimal safety performance and helps build a stronger safety culture.

Common Misconceptions

Several misconceptions about safety indicators can hinder their effective use:

Misconception 1

Lagging indicators aren't useful because they're reactive

Reality: While reactive, lagging indicators provide valuable insights into your safety program’s effectiveness and help identify areas needing attention.

Misconception 2

More leading indicators automatically mean better safety

Reality: Quality matters over quantity. Focus on relevant, actionable metrics that align with your specific safety goals.

Misconception 3

We only need to track OSHA-required metrics

Reality: While regulatory compliance is important, a robust safety program should include additional indicators that provide a more complete picture of safety performance.

“One thing we realized is that TRIR is a terrible indicator of a safety record. 7 medical-only recordable injuries will give you the same TRIR as 7 fatalities. We have started doing a lot more looking into SIF’s and Potential SIF’s so that our focus isn’t wasted on minor issues and we can prevent the big ones.”
– Chris Gafford, EHS Manager at Ring Energy

Implementing Effective Indicators

Understanding safety indicators is one thing – implementing them successfully is another. Many organizations struggle to move from theory to practice, but a systematic approach can make the difference between collecting meaningless data and driving real safety improvements. Whether you’re just starting out or refining an existing program, these six steps will help you maximize the value of your safety indicators:

  1. Choose relevant metrics that align with your goals. Select indicators that directly reflect your organization’s specific safety challenges and objectives, rather than simply tracking what’s easiest to measure.
  2. Set clear targets for each indicator. Establish specific, measurable benchmarks that give your team something concrete to work toward and help you gauge the effectiveness of your safety initiatives.
  3. Communicate the purpose and importance to all stakeholders. Help everyone understand not just what you’re measuring, but why it matters and how their actions contribute to safety improvements.
  4. Consistently collect and analyze data. Establish reliable data collection methods and regular review periods to ensure you’re capturing accurate, actionable information that can drive decision-making.
  5. Regular review and adjust your approach based on findings. Don’t just collect data – use it to identify trends, spot potential issues early, and make informed adjustments to your safety programs.
  6. Share results and celebrate improvements. Keep your team engaged by regularly communicating progress, recognizing achievements, and demonstrating how their efforts are making a difference in workplace safety.

Remember, the goal isn’t just to collect data – it’s to use that information to drive continuous improvement in your safety program.
