Lessons Learned Handbook:
Trending can focus on use of the LLIS, implementation of good work practices,
number of mistakes in a particular area or other elements that will provide useful
information if tracked over time. Trending is frequently used to identify and analyze
selected, similar events, including recurring equipment failures and generic underlying
problems. Trend reports should be issued on a regular basis and should highlight
issues of potential concern and the effects of steps taken to modify adverse trends.
For example, Virginia Power Company produces quarterly trend reports of their
operating experiences based on deviations that are tracked in a computer database.
Deviation reports are trended by overall program status, equipment/component/system
related problems, personnel/procedure related problems, and by specific problem
areas such as equipment, component, system, personnel, procedure, and common
cause. Deviation reports are evaluated to identify adverse trends, patterns, or potential
common failures and may result in a lessons learned action plan.
Developing Performance Measures for Lessons
1. Develop Lessons Learned Objective(s) for the Organization
Base performance measures upon mission and vision statements.
Identify PRODUCTS, CUSTOMERS, and PROCESSES.
May include ratios such as productivity (outputs to inputs), differences
such as profit (selling price minus input cost, or combination of several
State and define underlying "values" and quality factors.
Safety, rework, environmental soundness
State optimal direction.
DO NOT list activities, processes, or numerical quotas.
