Overview
High software costs and the fact that more than 65% of the software life-cycle time
is spent on testing and maintenance has created a considerable attention to the software
complexity problem. Over the last decade many software complexity measures have been
proposed by researchers. These measures are being used for analyzing software complexity,
software understandability, software modifiability, software testability, software
maintenance and for software development. The central goal of this textbook is to
provide readers with the necessary knowledge and tools for critically evaluating
existing and future software complexity measures. This book shall help scientists,
teachers, students and engineers of software departments to understand software measurement
in theory and apply software measures in practice. The book presents three major
ways to discuss software complexity measures.
The first one is a theoretical treatment of how measurement theory can be used to
assess software complexity measures. The problem interpreting the results of a software
measurement process, the methods of the application of measurement theory, the definition
and use of scales, the description of measures as an ordinal or ratio scale, and
the methods of the correct interpreting of the meaning of the numbers are presented.
The second one is a detailed analysis and description of the properties of just every
(more than ninety) published complexity measures (derived from flowgraphs) and a
consideration of the different assumptions which have to hold for the measures to
be used for various scales. Methods to analyze, to create, to discuss and to evaluate
software measures are shown. The different types of software complexity measures
are discussed. Criteria to perform meaningful statistical analysis with the resulting
numbers are given.
The third one is a proposal of how software measurement programs can be set up. Many
examples of the correct use of software complexity measures are given. The construction
of a software measure database is presented. Methods to compare versions of programs
using software complexity measures are proposed. A set of well defined software complexity
measures for applications in software reuse and generally in practice is discussed.
