Project Performance Management. Connecting the 5 Principles and 5 Practices of Performance-Based Project Management ® To Increase the Probability of Project Success. Building a Credible PerformanceMeasurement Baseline. Measures of Product Value is Exchange for Its Cost. Event-Based Scheduling , 10 November 2006.
I work in the Software Intensive System of Systems domains in Aerospace, Defense, Enterprise IT (both commercial and government) applying Agile, Earned Value Management, Productive Statistical Estimating (both parametric and Monte Carlo), Risk Management, and Root Cause Analysis with a variety of capabilities. NASA Cost Estimating Handbook.
The paper on the Cone of Uncertainty is used by many in the No Estimates community as an example of why estimates are of little use. In this paper, there is data that does not follow the Cone of Uncertainty, in that the uncertainty of the estimates does not reduce as the project proceeds. Then there is some analysis.
Project Performance Management (#PPM). Technical PerformanceMeasures (#TPM). Cost, Schedule, and Technical Performance Management (#CSTPM). Project Performance Management. Building a Credible PerformanceMeasurement Baseline - without a good foundation, nothing can be built. Risk Management (#RM).
When we hear about software development disasters and then hear that estimates are to blame, and NOT Estimating will somehow reduce or prevent these disasters, think again. Each of the categories operates in the presence of uncertainty and requires that estimates be made about the probability, conseqeunce of the resutling risk.

The Cone is a project management framework describing the uncertainty aspects of estimates (cost and schedule) and other project attributes (cost, schedule, and technical performance parameters). This is a closed loop control system for managing the program with a T echnical PerformanceMeasure (TPM).
The Cone is a project management framework describing the uncertainty aspects of estimates (cost and schedule) and other project attributes (cost, schedule, and technical performance parameters). Estimates are needed but are subject to large level of uncertainty. There can be cost and schedule performancemeasures as well.

All making things smaller dos is show that you're late, over budget, and what you're building (Technical PerformanceMeasures) doesn't work faster. But when some statement is made about risk, estimating, performance modeling, or the like - always ask for references. Stewart, ACTEX Publications, 2006. No References?
For approaches that have been implemented on existing systems, obtaining such understanding may require measurement and analysis. For scenarios where the project under consideration does not yet exist, performance prediction using analytical modeling or simulation is necessary. This is the basis of Earned Value Management.
