The Tenets of P.I.E.: A Tactical Decision-Making Matrix
Deputy Chief AJ DeAndrea (Ret.) held leadership roles during three school shootings that forever changed the fabric of American society and transformed law enforcement’s response to active shooter incidents worldwide: Columbine High School, Platte Canyon High School, and the Youth With A Mission (YWAM) shootings. These pivotal events, along with extensive real world experience, form the foundation of the P.I.E. Tactical Decision-Making Matrix, a
framework now utilized by law enforcement agencies, school districts, and corporations worldwide to guide decision-making under pressure.
The P.I.E. Matrix (Priorities, Intelligence, and Environment) was originally developed by Deputy Chief DeAndrea to help officers make solid, life-saving decisions in high-stress situations. It was then introduced to SWAT team leaders and later adopted as an operational philosophy across multiple agencies.
The framework emphasizes:
- Priorities – identifying and focusing on the most critical objectives during an incident.
- Intelligence – gathering, assessing, and applying actionable information to make informed tactical decisions.
- Environment – adapting to the dynamic circumstances, terrain, and situational factors in real time.
This decision-making tool provides responders with clarity, structure, and adaptability in the midst of chaos, ensuring actions remain focused, coordinated, and effective. Beyond tactical applications, P.I.E. serves as a universal framework for leadership, crisis management, and organizational preparedness, empowering individuals and teams to navigate uncertainty with confidence and precision.
Through examples from Columbine, Platte Canyon, YWAM, and other real world incidents participants gain rare insight into how this framework has been applied in life-or-death situations, offering practical lessons that can be implemented across agencies, organizations, and communities to strengthen decision-making, leadership, and resilience.
