Rabobank is reshaping its systems portfolio of Rabobank from dedicated product systems to a network of generic services with a shared data source. In this environment Function Point Analysis no longer fits the sizing needs. An alternative was found in the COSMIC Full Function Points method. Because of the absence of benchmark data a conversion formula was(More)
Triggered by new European legislation the Dutch Office for Regulations decided to renew major parts of their IT landscape with Oracle's E-Business Suite. They expect that this packaged solution offers the possibility of quick implementation of new business processes. For the implementation of new regulations and the redesign of existing ones, a software(More)
risks consequences size gross hours hours (& money) influences productivity The Expertise Centre Metrics of the Dutch Rabobank experienced problems in using Function Point Analysis for estimating development effort especially in contemporary platforms. As a result confidence in metrics decreased and management asked the Expertise Centre to look for a(More)
This article shows the first results of the adoption of COSMIC Full Function Points as a sizing method replacing function point analysis. The main arguments why COSMIC-FFP was chosen will be explained, the transformation plan will be shown together with the first results of the use of COSMIC-FFP. Next to the management requirement that the new functional(More)
—In 1998 NESMA published an alternative approach to establish the functional size of software enhancement projects. The aim of the approach was to be able to use productivity data from software development to estimate software enhancement. This approach has been highly debated, since it is not a pure functional size measurement method in the ISO/IEC 14143(More)
In this paper we explore opportunities, challenges, and obstacles that Functional Size Measurement (FSM) experts assume to be in automatically derived functional size, directly from the software project code itself. We designed a structured survey, that was answered by 336 FSM specialists. A majority of the respondents consider FSM to be an important tool(More)
We study whether an assumed positively skewed distribution of effort data prevents software estimators to learn over time; leading to increasing differences between planned and actual effort and a deteriorating (worsening) trend on productivity. We analyze data of 25 software releases of one application, collected over a period of six years in a public(More)
