The ‘Third Rail’ of Project Management: Cutting Quality Scope, schedule, and resources: Whether you’re using agile or more traditional project management approaches, this triple constraint is the law of the project universe. The unmentionable “third rail” of project management trade-offs is compromising quality to deal with the other two aspects. Don't make that an option. |
