Why Plans Fail

Book excerpt: Business runs on decisions. Business relies on estimates, plans, and projections - and we all know how accurate they tend to be. Careers are made, careers are broken based on perceived accuracy in estimation and planning. But what if the successes and failures of these projects were not based on the prowess of those making the plans? What if successes and failures were instead the result of a more complex set of events? What if our own cognitive biases - our own brains - were creating our inaccuracies, our poor assumptions, and our unreasonable expectations? Why Plans Fail directly addresses our ability to plan, to forecast, and to make decisions. Written by Jim Benson, author of the Shingo Research Award-winning Personal Kanban, urban planner, software developer, and business owner who has planned and built everything from small software projects, to houses, to urban freeway systems, Why Plans Fail is told by someone with much skin in the estimation and planning game. This short work is the first in the Modus Cooperandi MemeMachine series - which looks specifically at underlying issues that directly impact the success of teams, companies, and individuals. The Mememachine series is meant to start conversations and advance discussion.
