The Stress-Performance Curve (Yerkes-Dodson Law)

Achieving maximum performance from yourself and your team requires understanding the stress-performance curve as it relates both to individuals and types of work.

Stress for most people reading this will involve some combination of the following factors:

  • Time to complete the task - for instance a complex project proposal due in 3 days.  
  • Money or other things at risk - for instance; an interview for a complex project is coming up in 3 days and if you don’t win the project then you will have to lay off a project team as well as likely face a bad quarter.  
  • Overall workload - for instance; having the proposal and interview for the project in 3 days while still having the responsibilities for managing other projects and a team of people.

For a more complex task such as putting together the schedule for a two-year project, too much stress will impact productivity and quality leading to fatigue then burnout.  Too little stress won’t create the stimulation required for optimum productivity.  

For a simpler task such as the assembly of the final proposal documents into books is not nearly as impacted by stress with the performance curve going up and generally staying up even with high levels of stress.  


 

Consistently too much stress on the team as a whole could be a growth inflection point and could be due to overload which is defined as one of "The Three Enemies of Lean" in the lean body of knowledge.

Connecting Metrics to Activities and Outcomes
Outcomes are created through doing the right activities. Data is only a proxy for that activity and a metric is a synthesis of lots of data points. Metrics are valuable, but always have a skeptical view of proxies for performance, especially with growth.
Cranes and a Construction Business
There is a lot of intentionality around all aspects of every crane lift, including systems for double-checking and approvals. There is far less intentionality around the business equivalents for contractors and that dramatically impacts performance.
