What is lessons learned?
• Validated working knowledge derived from
successes or failures that, when reused, can
significantly impact an organization’s processes
• Hundreds of organizations have or plan to
develop LL processes with the goal of
enhancing:
– job safety, reducing costs, improving quality,
increased reliability and/or increasing problemsolving speed.

Lessons learned systems
• Sometimes implemented as knowledge management
solutions for documenting tacit lessons whose reusable
content can benefit targeted organizational processes.
• 5 LL sub-processes: collect, verify, store, disseminate,
and reuse
• LL systems have been used to support collection (e.g.,
online lesson submission forms) and dissemination
(e.g., standalone retrieval tools).

Problems associated with LL
• Standalone dissemination systems do not reflect
a central KM tenet:
– to be successful,knowledge dissemination methods
must be embedded in the processes they are
intended to support
• Typically under-utilised and do not promote
knowledge sharing and reuse.
