It's the Context, Stupid
Throughout our consultancy work and education, one key theme has emerged: Projects fail because of the context, not the content.
As we mentioned earlier, the traditional emphasis in project management on the technical issues of the project (content) has led to a legacy of an extremely poor set of tools, techniques, and tips for managing the complex of people, political, and other "softer" issues that make up the context of the project.
On our Web site is an article called "Project Pathology: Causes and Symptoms of Project Failure." It details our conclusions and learning from consulting on over 20 major projects that had failed. All the failures were in managing the context rather than the content.
