Bandura's social cognitive theory can provide a general basis, because as individuals in an organization, we learn from one another almost unconsciously.  But the popular theories that support organisation learning are the single loop and double loop concepts.

"Single-loop learning occurs when an organization detects a mistake, corrects it, and carries on with its present policies and objectives. Double-loop learning occurs when an organization detects a mistake and changes its policies and objectives before it can take corrective actions." (From Wikipedia)

In my institution, we were asked to have PLCs (professional learning communities) so that teachers learn from one another.  We were encouraged to do lesson studies, where colleagues observed student actions and reactions in a class.  Colleagues will then meet with the person who taught the lesson, who might have missed cues from students, that would have improved the lesson if taken into account.  The bosses in the education ministry supported this.  Surely, lessons may be better planned if teachers knew that 'knowledgeable colleagues' would be observing their lessons.  We practice the single loop concept.  Thanks.
