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. Performance-Based Project Management in a Nutshell. Project Breathalyzer.
Project Performance Management (#PPM). Technical PerformanceMeasures (#TPM). Cost, Schedule, and Technical Performance Management (#CSTPM). But each method needs to be based on 5 Immutable principles to be successful, no matter the domain or context, PMI Spring Seminar , 2012, Austin TX. Risk Management (#RM).
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.
Estimated Project-Oriented Job Openings 2010-2020: . Implement/enhance performancemeasurement process – 39%. [13]. Number of companies with a PMO has grown from 47% to 80% from 2000-2012. Inadequate cost estimates – 29%. Inaccurate task time estimate – 27%. 8,153,340. . 3,975,650. . 2,348,830. .
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 of Uncertainty as a Technical PerformanceMeasure. Of late, Cone of Uncertainty has become the mantra of No Estimates advocates claiming that data is needed BEFORE the Cone is of any use. Thesis, University of Southern California, August 2012. The Cone of Uncertainty as a Technical PerformanceMeasure.
Reducing Estimation Uncertainty with Continuous Assessment: Tracking the 'Cone of Uncertainty’” Pongtip Aroonvatanaporn, Chatchai Sinthop and Barry Boehm, Center for Systems and Software Engineering University of Southern California , Los Angeles, CA 90089, ASE’10 , September 20–24, 2010, Antwerp, Belgium, 2010. 37–48, 2007.
This is an immutable principle that impacts planning, execution, performancemeasures, decision making, risk, budgeting, and overall business and technical management of the project and the business funding the project no matter the domain, context, technology or any methods. All project work operates in the presence of uncertainty.
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. This is good, but it doesn't reduce risk.
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.
