Project success needs the business to complete implementation and achieve the resulting business outcomes.
Why do so few projects succeed?
Measuring project success using the Iron Triangle (or triple constraint of time/cost/specification) does not measure why you do projects (which is to obtain value).
Rather, it diverts attention away from the real measures of success and can encourage the destruction of value.
We add the Value Triangle to define and measure our project success in business outcomes and benefits in this 12 minute video.
