RT Journal Article SR Electronic T1 Learning from samples of one or fewer JF Quality and Safety in Health Care JO Qual Saf Health Care FD BMJ Publishing Group Ltd SP 465 OP 471 DO 10.1136/qhc.12.6.465 VO 12 IS 6 A1 J G March A1 L S Sproull A1 M Tamuz YR 2003 UL http://qualitysafety.bmj.com/content/12/6/465.abstract AB Organizations learn from experience. Sometimes, however, history is not generous with experience. We explore how organizations convert infrequent events into interpretations of history, and how they balance the need to achieve agreement on interpretations with the need to interpret history correctly. We ask what methods are used, what problems are involved, and what improvements might be made. Although the methods we observe are not guaranteed to lead to consistent agreement on interpretations, valid knowledge, improved organizational performance, or organizational survival, they provide possible insights into the possibilities for and problems of learning from fragments of history.
