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)
The COSMIC method provides a standardized way of measuring the functional size of software from the functional domains commonly referred to as 'business application' or 'Management Information Systems' (MIS) and 'real-time' software, and hybrids of these. In practice it is often sufficient to measure a functional size approximately. Typical situations where(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)
With version 3.0, the COSMIC functional size measurement method reached maturity, offering a stable framework for detailed documentation of the method. The most detailed level of documentation is the Case Study, a fully documented functional size measurement of a piece of software. For the understanding and propagation of the COSMIC method it is important(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)
