- W4234488085 abstract "Abstract Though engineers and managers routinely express the desire to learn from previous project experience, we typically do not learn effectively from our project experiences. The failure to learn valid and valuable lessons from project experiences can be attributed to a number of cognitive and social factors, which will be discussed below. Fortunately, there is a great deal of literature in the fields of decision theory and cognitive science that is relevant to the subject. Unfortunately, much of this literature is unknown to most practicing engineers. This paper presents a structured method for identifying learning limits, an introduction to current thinking in areas of knowledge required to implement the method, a summary of the results of applying of the method, and suggestions for improving our ability to learn from project experiences. Introduction In the 1950's the French fought a war in Vietnam. After a protracted struggle the French gave up and withdrew. A decade later the US repeated the French experiment in the same country, producing the same results. Many parallels can be drawn between the French and American experiences in Vietnam: In each case an apparently vastly superior force (France, US) waged war on an apparently hopelessly inferior opponent. Both the French and the Americans vastly underestimated the determination of the enemy. In both conflicts, the North Vietnamese proved to be much more motivated to succeed than the outsiders. Success for the North Vietnamese required simply that they survive until the enemy gave up. Given the situation, the North Vietnamese had a much more effective strategy than the foreign armies. Both the French and US public became increasingly hostile to the war effort as time progressed. Similar assessments can be made with regard to the USSR engagement in Afghanistan and the current war in Iraq and, to a lesser extent, the Peloponnesian War between Athens and Sparta 2400 years ago. Though each of these wars is different in significant ways, it is also clear that some lessons could have been learned from each, but were not. The Guide to the Project Management Body of Knowledge (PMBOK) by the Project Management Institute (PMI), now in its third edition, has been adopted as an American National Standard (ANSI /PMI 99–001-2004). PMBOK suggests that organizations capture lessons learned as a discrete step at each stage of project execution. In the book's index, the term lessons learned appears 34 times. Clearly, the authors recognize that effective learning is an important part of project management. However, it is interesting to note that the term lessons learned is not discussed anywhere in the book beyond a short description in the glossary. The other 33 entries amount to only simple admonishments to do it. Compare this to cost estimating, a conceptually simple subject to which an entire chapter is devoted. Since PMBOK clearly identifies learning lessons as an important task, but spends no effort describing how to do it, we must assume that the authors believe that learning in a project setting is obvious and easy. We do not believe that learning is easy. It is our premise that learning valid lessons from projects is in fact quite difficult due to a number of social and cognitive factors. This paper attempts to comprehensively identify the most important limiting factors. It is only by addressing these root causes of our learning disability that we can expect to identify solutions. What is Learning? Learning is any increase in knowledge or skills which enables the learner to be more effective at planning and implementing actions which achieve the actor's objectives. Faced with a significant problem we expect an individual to do the following:Collect and evaluate data in order to develop an assessment of the current situation.Develop objectives and identify alternatives to change the current situation.Evaluate the alternatives to identify the best.Take action to implement the selected alternative." @default.
