Practical Applications of ISBSG Data

Harold Van Heeringen has extensively used ISBSG Data as a benchmarking tool for client organizations. In this webinar, Harold uses his expertise to demonstrate how ISBSG data (in Excel-format and via the ISBSG Productivity Data Query Tool) can be used to improve estimation and planning.

Re-evaluation of Estimation Study Results using ISBSG Data

This webinar evaluates any differences between replications of research studies that used ISBSG data, to estimate software-effort.

ISBSG data for Process Improvement

Data is a valuable project asset. It guides project estimation, team performance measurement, vendor contracting and benchmarking. Discover how data can be used to improve the IT processes of your organization.

Analysis of Velocity (Speed of Delivery)

The differences between the Agile concept of velocity and the traditional  idea of delivery speed is discussed. The results from analyzes of Velocity (Delivery Speed) of recent, Java projects in the ISBSG repository is displayed. In particular, the Delivery Speed of projects within different functional-size groupings is considered.

software cost

Project Cost per FP

‘Cost per Function Point’ is an industry best practice to ensure that both the customer and the supplier benefit from high productivity. This short paper analyzes the cost and functional size of projects from the ISBSG Repository.


CRM Projects

This short paper determines whether there are key factors that influence the productivity and delivery speed of CRM projects.


Legacy Applications

This short paper examines a high-level business case to to rebuild a Cobol legacy application in Java. ISBSG Data, for similar Java projects, provides metrics for: cost, effort, maintenance and support. This information is used as the basis for the business case.

Cobol Projects

We examine number of COBOL Projects submitted to the ISBSG Repository, since the year 2000. The median Project Delivery Rates are compared to determine whether there has been an in increase in productivity for COBOL projects.


Output Based Contracting

In this short paper, we explain the way ISBSG data can be used to contract application development teams based on output instead of the usual Time & Materials method.

Productivity Data Query Tool (PDQ)

You specify your project attributes then the interactive, ISBSG PDQ displays similar projects from the ISBSG Development & Enhancement Repository. Productivity estimates are generated from this data.  The estimates can be used as a benchmark for your project.

The generated estimates are: software project effort, project delivery rate, project duration, defect density, project effort and speed of delivery.

Find out more details on how to use the PDQ.
