  • Software Metrics: Successes, Failures and New Directions
    Software Metrics: Successes, Failures and New Directions Norman E Fenton Centre for Software Reliability Agena Ltd City University 11 Main Street Northampton Square Caldecote London EC1V OHB Cambridge CB3 7NU United Kingdom United Kingdom Tel: 44 171 477 8425 Tel 44 1223 263753 / 44 181 530 5981 Fax: 44 171 477 8585 Fax: 01223 263899 [email protected] [email protected] www.csr.city.ac.uk/people/norman.fenton/ www.agena.co.uk Abstract The history of software metrics is almost as old as the history of software engineering. Yet, the extensive research and literature on the subject has had little impact on industrial practice. This is worrying given that the major rationale for using metrics is to improve the software engineering decision making process from a managerial and technical perspective. Industrial metrics activity is invariably based around metrics that have been around for nearly 30 years (notably Lines of Code or similar size counts, and defects counts). While such metrics can be considered as massively successful given their popularity, their limitations are well known, and mis-applications are still common. The major problem is in using such metrics in isolation. We argue that it is possible to provide genuinely improved management decision support systems based on such simplistic metrics, but only by adopting a less isolationist approach. Specifically, we feel it is important to explicitly model: a) cause and effect relationships and b) uncertainty and combination of evidence. Our approach uses Bayesian Belief nets which are increasingly seen as the best means of handling decision-making under uncertainty.

  • Objectives and Context of Software Measurement, Analysis, and Control Michael A
    Objectives and Context of Software Measurement, Analysis, and Control Michael A. Cusumano Massachusetts Institute of Technology Sloan School WP#3471-92/BPS October 8, 1992 Objectives and Context of Software Measurement, Analysis and Control Michael A. Cusumano Sloan School of Management Massachusetts Institute of Technology Cambridge, Massachusetts USA 02142 Abstract This paper focuses on the what and why of measurement in software development, and the impact of the context of the development organization or of specific projects on approaches to measurement, analysis, and control. It also presents observations on contextual issues based on studies of the major Japanese software producers. 1 Introduction This paper focuses on the what and why of measurement in software development, and the impact of the context of the development organization or of specific projects on approaches to measurement, analysis, and control. It begins by discussing three basic questions: (1) Why do we measure? (2) What is it we want to know? And (3) how does the context affect the ability to measure? The second section presents observations on contextual issues based on my ongoing study of the Japanese [3]. This paper also relies heavily on extensive interviews conducted at Hitachi, Fujitsu, NEC, and Toshiba during May, August, and September 1992. 2 Basic Questions Why we measure aspects of the software development process and conduct analytical exercises or experiments, as well as what we try to do with this information, depends very much on who is doing or requesting the measuring and analysis. There already exists a broad literature on technical aspects software measurement and the relationship to process management, which will not be reviewed here [1, 2, 5, 6].

  • An Approach for Deriving, Analyzing, and Organizing Requirements Metrics and Related Information in Systems Projects
    An Approach for Deriving, Analyzing, and Organizing Requirements Metrics and Related Information in Systems Projects Ibtehal Noorwali1, Nazim H. Madhavji1 and Remo Ferrari2 1Computer Science Department, The University of Western Ontario, London, Ontario, Canada 2Siemens Mobility, New York, NY, U.S.A. Keywords: Requirements Metrics, Requirements Management, Measurement Approach. Abstract: Large systems projects present unique challenges to the requirements measurement process: large sets of re- quirements across many sub-projects, requirements existing in different categories (e.g., hardware, interface, software, etc.), varying requirements meta-data items (e.g., ID, requirement type, priority, etc.), to name few. Consequently, requirements metrics are often incomplete, metrics and measurement reports are often unor- ganized, and meta-data items that are essential for applying the metrics are often incomplete or missing. To our knowledge, there are no published approaches for measuring requirements in large systems projects. In this paper, we propose a 7-step approach that combines the use of the goal-question-metric paradigm (GQM) and the identification and analysis of four main RE measurement elements: attributes, levels, metrics, and meta-data items—that aids in the derivation, analysis, and organization of requirements metrics. We illustrate the use of our approach by applying it to real-life data from the rail automation systems domain. We show how the approach led to a more comprehensive set of requirements metrics, improved organization

While some of these difficulties semantic knowledge and multi-agent quality goal tracking and might be ascribed to a misaligned planning environment in decision-making.
