Software Data Collection Study. Volume II. An Analysis of Software Data Collection Problems and Current Capabilities.

摘要

The current state of software data collection leaves much to be desired. There is no comprehensive base of software development information, and the data that are gathered lack reliability, accuracy and validity. Data gathered from diverse sources and projects are not comparable due to a lack of standardization in meaning, measuring techniques and collection procedures. One of the chief obstacles to gathering more reliable data are project resistance to managerial control and reluctance to release data that might reflect on project efficiency or reveal proprietary technology. This report reviews the literature dealing with software data collection problems, evaluates current military data collection practices, and surveys briefly some project monitor systems that could aid in the collection of more valid and reliable data. The alternatives available in managing a software data collection operation facility are also examined. Actions leading to objective, reliable and standard measures and for removing some of the subjectivity of measures are considered. No easy or fine solutions are seen, but improvements are attainable to technological and managerial changes and through economic inducements to provide better data. (Author)
