Move past blame and quick fixes by examining all six factors that influence performance. Then, create a targeted improvement plan.

Overview

When an employee is not performing as expected, you may spend a lot of time and effort trying to help your employee improve only to be left with continued performance problems. That’s because there can be many reasons for the lack of performance, and it’s not always easy to spot the root cause. As a supervisor, you need to examine which organizational and personal factors are most contributing to the performance issues.

This worksheet uses Carl Binder’s Six Boxes® model — adapted from Thomas Gilbert’s research-based Behavior Engineering Model — to systematically diagnose a performance issue with one of your direct reports. It helps you move past blame and quick fixes by examining all six factors that influence performance so you can formulate a targeted improvement plan.

After registering, you will see two buttons appear on the right side of the screen:
