While creating estimates is a fundamental step toward improving productivity on software development projects, it is not enough. In "Full-Circle Estimating," recently published on Projects at Work, Doug Putnam and Taylor Putnam-Majarian present a full-circle model that organizations can apply to track actual performance against estimates, reforecast when significant changes occur, and then continually refine the process through post-mortem assessment.
Doug Putnam is co-CEO for Quantitative Software Management (QSM). He has 35 years of experience in the software measurement field and has been instrumental in the development of the SLIM Suite of software estimation and measurement tools. C. Taylor Putnam-Majarian is a consulting analyst at QSM with over seven years of specialized data analysis, testing and research experience. In addition to providing consulting support in software estimation and benchmarking engagements to clients from both the commercial and government sectors, Taylor has authored numerous publications about Agile development, software estimation and process improvement.
