PERSONNEL IS-EFFORT COLLECTION IN INDUSTRIAL ENVIRONMENTS

The knowledge of development and maintenance effort is a necessary precondition for alltypes of software management, IS-controlling, guidance of quality and effort estimation. Data collectingsystems seem to be widely used, but the data is said to be unsafe and firm-specific. This paperpresents a concept for the collection of personnel effort and for events (e.g. faults). The revised informalspecification of this paper is based on experience with such a system used by 40 developers infive locations for many years. Design and practical use of a system based on that concept allow thecollection of statistically valid effort data.
