When there is a problem with workplace performance, look at the "before and after" -- what came before and after the performance.  Often a performance gap can be attributed to one of these important factors.

Before the workplace performance . . . .

• Was there a clear agreement on desired performance?
• Were incentives and reward systems aligned with the desired performance?

After the workplace performance . . .

• Was there a consequence for the difficult behavior or undesired workplace performance?
• Was there ever positive reinforcement given to the employee for the desired performance?
