Project Success - "Projects are like Chalk and Cheese"

This is the third part in my thoughts on Project Success:

• In part 1, I posed the question "How do you measure Project Success?"
• In Part 2, I explored Project Success from different perspectives and provided some links to sources that explored factors in project success and to improve the chance of success beyond serendipity.

The key points from the first two parts are:

• Project Success cannot be judged by the triple constraint.
• The triple constraint of time cost and scope only address the project efficiency dimension of success.x
• Different projects have different success measures depending on your point of view as a stakeholder
• Shenhar and Dvir identified five dimensions of success which could be used as a model to identify the success criteria for a project
• Success criteria has to be built into the project from the first step and then reflected in its plan, demonstrating how the project will deliver the outcome

I believe this evidence also points to the need for an organisation to develop its PM reward system to be based on more than just the traditional triple constraint.
