Leveraging QSM's industry database of over 13,000+ completed projects, Katie Costantini takes a high-level look at changes to software schedules, effort/cost, productivity, size, and reliability metrics from 1980 to 2019.
In this article for Software Executive Magazine, Larry Putnam, Jr. explains how focusing on scope-based estimates, agile forecasting, and smaller teams will help your development team deliver products on time and according to budget.
Employing a top-down estimation approach to project management can help organizations overcome boundaries and satisfy the three V’s of corporate success – vision, value, and velocity. This article, originally published in ISV Insights, takes a closer look at how this approach can work for software companies, particularly larger organizations, to help them improve project management, team collaboration, and development practices.
Like their software counterparts, IT infrastructure projects are more likely to be successful — more efficient, secure, and reliable — when accompanied by robust estimation and planning processes. In this article for ProjectManagement.com, Larry Putnam, Jr. and Joe Madden identify best practices for applying parametric estimation to IT infrastructure projects.
In order to use a sizing unit other than SLOC in the SLIM tools, you must assign a gearing factor. For function points, gearing factors are discussed here. In this article, QSM's Andy Berner addresses ways of choosing a gearing factor for story points.
This article continues the focus from the previous article on determining size in a consistent enough manner across multiple products, projects, and agile teams so that you have good historical data on which to base an estimate. QSM's Andy Berner looks at other sizing units besides story points, in particular function points and source lines of code.
Part of QSM's Agile Round Table article series, the fourth article focuses on determining size in a consistent enough manner across multiple products, projects, and agile teams so that you have good historical data on which to base an estimate. It also shows how to apply these techniques with the SLIM Suite of products.
A recent initiative put forth by the DoD was to improve its estimation process by leveraging historical data collected from forensic analyses of recently completed software development efforts. This article by Taylor Putnam-Majarian and John Staiger, discusses (1) some of the challenges faced throughout this initiative, (2) the data collection process, and (3) how one can leverage data to improve cost estimates. This article was originally published in Crosstalk Magazine.
In this article for IFPUG's Metric Views, Carol Dekkers and Joe Madden suggest a new way to repurpose function points to achieve software project estimating successes today.
Aaron Jeutter, a participant in the QSM Agile Round Table from Rockwell Automation, presents the technique of “Big Rock Sizing.” This technique is used at Rockwell Automation for early sizing and estimating based on high level requirements that will be refined using agile techniques as the work progresses.
