When to use it
Use it when there's a mistake or failure on your team. Focus on what caused it and how to prevent it next time. When people fear blame, they hide problems. When they expect problem-solving, they raise problems early.
Example
Team member: “The release broke the login page.”
You: “Let's figure out what caused this so it doesn't happen again.”
In an email or Slack message
In a team channel: “Login issue is fixed. Let's do a short review Thursday to find the cause and add a check so it doesn't happen again. No blame, just fixes.”
