The Three Secrets of Megaproject Success: Clear Strategic Vision,Total Alignment,and Adapting to Complexity

Past studies have often voiced concern that important megaprojects have repeatedly failed due to extensive overruns, misunderstanding of expectations, or both. In this article, we contend that this pattern may not be inevitable. In retrospect, despite painful delays, some megaprojects eventually achieved their longer-term objectives. In this study, rather than asking why megaprojects fail, we asked whether these notable (and rare) accomplishments have anything in common. We found that successful megaprojects are distinguished by three major elements: clear strategic vision, total alignment, and adapting to complexity.
