The PPI Error Elimination TOOLs™ App offers 15 simple TOOLs, proven to virtually eliminate the potential for making mistakes while doing work.

These TOOLs have been developed, refined, and used extensively by the US commercial nuclear and US airline industries. These are the same TOOLs used by the Nuclear Industry over the past two decades to increase capacity factors from 70% to 92% while achieving a more than ten-fold reduction in the OSHA Illness and Injury Rate.

At the Practicing Perfection Institute, Inc. (PPI), we’ve taken these TOOLs and made them fast, simple, and easy to use.

Each TOOL is broken down- WHY to use it, WHEN to use it, and HOW to use it. This is done to make them tangible and easy to understand, as well as for group discussion before starting a job.

Performance Improvement

When used properly, these TOOLs virtually eliminate the potential for making mistakes while work is being performed. This greatly improves performance, specifically- Reliability, Efficiency, Productivity, and Safety (REPS).

There are (15) Tools in all.
