Please join us online as we explore the Human Performance concepts, tools and techniques that Lewis Tree Service is applying to create safety in utility vegetation management. And visit our Events page to look for future webinars—we hold them bimonthly!


Webinar 1: Adaptive Capacity

You don’t have to be a safety professional to enjoy learning about Human Performance and Adaptive Capacity. Watch our first Lunch & Learn webinar and feel free to reach out to us (and subscribe to our blog!) to learn more.

Intro to New View Safety: Before jumping into Adaptive Capacity, we start by sharing our journey from Safety I to New View Safety—including the Lewis definition of Human Performance and how we’ve begun embracing that our work is highly variable.

Building Adaptive Capacity: The study of Human Performance reveals that a key to reaching desired safety outcomes starts with an understanding that safety scientists share: discipline and control are not as effective in creating safety as we think.

Together, we discuss the importance of building adaptive capacity (resilience, flexibility, options) to reduce incidents with serious injury potential.


Webinar 2: Leadership Response to Failure

A key principle of human performance is “error is normal—even the best make mistakes.” That’s why at Lewis, we no longer impose an automatic, three-day suspension after an incident occurs. In this session, we will share the thinking behind that change along with the a) event decision tree that we implemented to aid our field leaders in determining the right response and b) leadership language that we’re adopting to shape culture and model learning.


Webinar 3: Action-based Learning

Have you ever guessed the height of a tree by using a stick as a measurement gauge? Better yet, have you competed with others to see whose guess was the closest? In this session, we discuss how Lewis has fully integrated Human Performance learning into our weekly safety practices (i.e., action-based vs. formal training). And we share the structure and practices of our Learning Plan which includes storytelling, learning loops, safety drills, and more—while having some fun in the process! 


Webinar 4: After-Action Reviews

Have you ever planned a project or task and had to take a wildly different path to complete it? At Lewis, we call that “work as planned (or imagined)” versus “work as done.” We use After Action Reviews as opportunities to have a conversation about what happened, what surprised us, what we learned, and more.

In this session, we discuss how Lewis crews are purposely taking the time to reflect and share their experiences from different perspectives to deepen learning, accelerate expertise, and strengthen teams. We share how we are using AARs to check the pulse of our system in real-time. And we explore the pros/cons of formal versus informal AARs.


Webinar 5: Situational Awareness

“It happened so quickly.” We’ve heard this time and time again. In highly variable work, surprise is inescapable. By strengthening our situational awareness muscles, over time we may be more able to look for hidden traps, rely on a catalog of experiences, and predict/prepare for an unforeseen event.

In this session, we discuss how Lewis is studying/applying both the science and practices of individual and team situational awareness. We introduce our press pause tool for noticing, understanding, and forecasting what could happen next. And we’ll share our latest thinking on active spotting, confirmation bias, team communication, and more.


Webinar 6: Reframing Risk as Uncertainty

Have you ever conducted a traditional tree risk assessment, identified multiple risk factors (e.g., decaying base, dead limbs overhead, nearby power lines), and then asked yourself, “now what”? At Lewis, we had an “a ha” moment when we realized that the things that kill workers are not the things with the highest perceived risk but seem to be the things that are the most difficult to control.* In other words, the level of uncertainty or controllability is subjective and differs based on the length of service, depth of knowledge, risk tolerance, etc. of the individual.

In this webinar, we introduce methods and HuP tools like the Lewis Uncertainty Gauge to help manage uncertainty and uncover recurring patterns of risk.


KnowledgeVine Webinar: Implementing Safety Differently

Surprises are frequent, yet seldom acknowledged nor prepared for in ordinary work situations. We explore the practical application of fundamental Resilience Engineering premises “surprise will happen” and “work is variable” to the tree industry. At Lewis Tree Service, we perform the high-risk jobs of removing trees near power lines including trees on downed power lines after storms. On this KnowledgeVine webinar, we share our experiences translating New View Safety and Resilience Engineering theories into practical actions.

Please join Beth Lay, Lewis Tree Service, and Asher Balkin, the Cognitive Systems Engineering Lab at the Ohio State University, as they present Implementing Safety Differently and share their tools and practices for managing highly variable work.
