Deconstructing The Cone of Uncertainty

Herding Cats

Landmark’s measure of success over these three years had much more to do with customer satisfaction and market share than with meeting knowingly aggressive targets. It's suggested from observations, the Cone of Uncertainty (CoU) is not a valid model of how uncertainty behaves in software development projects. 37–48, 2007. .

Cone of Uncertainty - Part Cinq

Herding Cats

When actual measures of cost, schedule, and technical performance are outside the planned cone of uncertainty, corrective actions must be taken to move those uncertanties inside the cone of uncertanty, if the project is going to meet it's cost, schedule, and technical performance goals. . IEEE Software, March-April 2009, pp.
