What would you do differently if the situation occurred again?

The Critical Incident Method
The objective of the critical incident method is to identify both desirable and undesirable behaviors that resulted in either a very good outcome or a very bad outcome on the job. For example, a job analyst might ask a company’s customer service employees to describe incidents that led to either a good or bad outcome with a customer. The following are examples of questions that might be asked:
What happened?
How did the incident happen?
Did the incident have a good or bad outcome?
What led to the outcome?
What actions were effective or ineffective?
