There are at least five distinct and important areas where individuals being aware of and managing their personality tendencies have a significant impact on the traditional human performance system…



The “human performance system” is how the people, programs, processes, work environment, organization and equipment all interact with each other, act on the individual and the individual acts on them. Individuals being aware of and managing their tendencies enables a more effective interaction of the individual with this system, reducing errors and events. The other four areas of impact reflect this interaction. This system is surrounding tasks at home, work and play. This system equally impacts safety, quality, effectiveness, efficiency and productivity. People will use this system because it works for THEM.



Traditional human performance integration requires the use of very specific definitions for things like errors, events, deviations, violations, causes, traps, triggers and tools. Leaders who commit to using these science-based definitions see faster and more effective integration of the HP concepts into the day-to-day work. In addition, understanding our tendencies (and those of others), along with the definitions helps people in the organization more specifically comply with the definitions, providing almost immediate consistency and move towards sustainability.



There are three mental models called performance modes that people float in and out of all day. They were determined by research in the 1960s. They are based on THIS PERSON on THIS TASK at THIS TIME. It does not matter how many times an organization has done a task, only how many times the person doing it THIS time has done it impacts their mental model. E-CHP is about improving performance at the TASK and STEP level.

Skill based – things we do out of habit, not thinking, using low or no conscious thought. The tasks contain less than 7 discrete steps and must be done >50 times successfully over a short period to allow someone to perform in this mode. There is a relatively low error rate of 1:1000 in this mode, approximately 3x better than the standard human failure rate.

Rule Based – there is a rule and you know there is a rule (agreement that an expectation exists). People cannot know all rules, so they have to know a rule exists so they can go find it. SOPs, JSAs, WIs are all examples of rules, however all rules are not written. The error rate for this mode is 1:100 when things are done from memory and there are up to 7 steps. If there are more than 7 steps and done from memory it increases the error rate exponentially. Tasks that use a correct and well written rule reduces error rate by a factor of 10.

Knowledge Based – you don’t know what you don’t know. There are gaps in your information, and your mind knows that the gap exists, but does NOT know the answer. This is exhibited by people scratching their heads, saying phrases like “I think”, “I believe”, “I am almost sure”. Whenever these “triggers” exist, the error rate is 1:2-1:10 (50%-10%).

Both the Equilibria data and traditional human performance studies have shown that people must manage their tendencies to ensure they identify their (and those around them) shifting performance modes, especially when shifting to knowledge based mode. This enables them to use the right tool the right way to effectively reduce the error rate.



Traps are hidden elements that increase the probability for error.
Triggers are clues or cues (using the 5 physical senses and intuition) that a trap exists.

E-CHP development has revealed that, based on our tendencies, we set different traps in different ways for different personality styles. In return, those different personality styles set traps differently for us. When individuals are aware of and manage their tendencies, the ability to see the triggers and deal with the traps is significantly increased over the traditional generalized science of human performance.



Traditional human performance offers a wide variety of tools for the person on the task to pull from to reduce their probability for error.

Adding the tool of Personal Intervention as the gateway, significantly increases the probability that this person on this task at this time will use the right tool the right way to reduce the probability of an error that could result in an event. Each time the right tool is used the right way, the error rate on that task is reduced by a factor of 10.
