Premortem: Anticipating Failure Before It Happens
A premortem is a management and decision-making technique used to anticipate possible failures in a project before they happen.
Instead of waiting for problems to appear, the team imagines that the project has already failed and then works backward to discover what could have caused that failure.
This method helps teams become more careful, realistic, and prepared before starting important work.
What Is a Premortem?
The word premortem means:
Pre = before
Mortem = death or failure analysis
A premortem is the opposite of a postmortem.
Postmortem = analyzing why a project failed after it failed
Premortem = predicting why a project might fail before it starts
The goal is to reduce mistakes and improve project success.
How a Premortem Works
1. Set the Stage
The team assumes that the project has already failed completely.
The manager asks questions such as:
“Imagine this project failed six months from now.”
“What went wrong?”
“Why did we fail?”
This creates a mindset that encourages honest thinking.
2. Brainstorm Reasons for Failure
Each team member lists possible reasons why the project failed.
Examples:
Poor communication
Budget problems
Weak planning
Delayed materials
Lack of manpower
Client changes
Technical mistakes
Safety problems
Schedule delays
Everyone is encouraged to speak openly without fear.
3. Analyze and Prioritize Risks
After brainstorming, the team reviews all risks and identifies:
Which risks are most likely
Which risks are most dangerous
Which problems could create the biggest impact
The team then prioritizes the most important risks first.
4. Develop Preventive Actions
The team creates solutions to prevent or reduce those risks.
Examples:
| Risk | Preventive Action |
|---|---|
| Material delays | Order materials earlier |
| Poor communication | Hold daily coordination meetings |
| Budget overrun | Add contingency budget |
| Schedule delay | Increase manpower or overtime |
| Design changes | Improve client approval process |
5. Improve the Project Plan
Finally, the team updates and improves the project plan based on the lessons learned from the premortem.
This helps the project become:
Stronger
More realistic
Better organized
Less risky
Benefits of a Premortem
1. Identifies Risks Early
Problems are discovered before they become real issues.
This saves:
Time
Money
Energy
2. Encourages Critical Thinking
Team members think more deeply and honestly about the project.
It creates better discussions and smarter decisions.
3. Reduces Overconfidence
Sometimes teams become too confident and ignore hidden risks.
A premortem helps teams stay realistic and careful.
4. Improves Planning
The project plan becomes more detailed and practical.
This increases the chance of project success.
Example of a Premortem in Construction
Imagine a construction team is building a house project.
The manager asks:
“Imagine the project failed and finished three months late. Why?”
The team answers:
Rain delayed foundation work
Materials arrived late
Workers were insufficient
Client changed the design many times
Poor coordination between subcontractors
The manager then creates solutions:
Prepare rain protection plans
Order materials earlier
Add backup workers
Freeze design approvals earlier
Hold weekly coordination meetings
As a result, the project becomes more organized and prepared.
Simple Formula
Good Project Management = Planning + Risk Awareness + Prevention
A premortem strengthens all three areas.
Final Thought
A premortem is not about being negative.
It is about being prepared.
Strong leaders and successful teams do not only hope for success — they actively search for possible failures before they happen so they can prevent them early.
