Understanding Software Estimation, Negotiation, and Enterprise Demand Management: An Executive Primer


Historically, only 20% of software projects are completed successfully and with software becoming critical to nearly every company and industry, having such a high rate of failure is simply unacceptable anymore. It is for this reason that QSM has recently released, “Understanding Software Estimation, Negotiation, and Demand Management,” a collection of articles that will aid anyone from project managers to CIOs in implementing software estimation, negotiation and demand management methods efficiently to reduce costs.

Larry Putnam, Sr., founder of QSM and a pioneer and top problem solver in the software estimation and measurement field, provides the foreword to the book, which is co-authored by his son and granddaughter, Doug Putnam and Taylor Putnam-Majarian. Combined, the authors bring more than 40 years of experience in software measurement to a range of topics.

Five Core Metrics: The Intelligence Behind Successful Software Management
Lawrence H. Putnam and Ware Myers


In their newest book, authors Lawrence H. Putnam and Ware Myers leverage a large database of completed software projects to show how software projects can be planned, tracked, and controlled using Five Core Metrics. By focusing on a tried and true metric set (Time, Effort, Size, Reliability, and Process Productivity), managers can assess risk factors, anticipate surprises that cause project failure, respond to changing conditions, and replan with confidence.

"...an invaluable resource for project managers and project leaders... managers bombarded with software measurements will find what Putnam and Myers refer to as the 'five core metrics' to be a welcome solution to their metric woes."
