Measuring the Psychological Complexity of Software Maintenance Tasks with the Halstead and McCabe Metrics Abstract: Three software complexity measures (Halstead's E, McCabe's u(G), and the length as measured by number of statements) were compared to programmer performance on two software maintenance tasks. <> We've defined these metrics below for your reference. 1 0 obj endobj The following software metrics are summarized.

Halstead’s Software Science metrics. Cyclomatic complexity (also referred as program complexity or McCabe´s complexity) is the most widely used member of a class of static software metrics. rics, McCabe and Halstead, indicate that the approach is sound, thus serving as the groundwork for further exploration into the analysis and design of software metrics. 3. The cyclomatic complexity has been introduced by Thomas McCabe in 1976. It measures the number of linearly-independent paths through a program module.

Used as a quality metric, gives relative complexity of various designs. In an experiment on understanding, length and u(G) correlated with the percent of statements correctly recalled. All three metrics correlated with both the accuracy of the modification and the time to completion. 3) Run on Solaris. 8)�߸��H"^�(�ss S Halstead made the observation that metrics of the software should reflect the implementation or expression of algorithms in different languages, but be independent of their execution on a specific platform. Command-line Usage. B. Curtis, S. Sheppard, P. MillimanThird time charm: Stronger prediction of programmer performance by software complexity metrics … McCabe’s, Myers’ and Hansen’s cyclomatic complexity metrics. X��������nΎ %$5��σ4�'���(d��0� ��Z� Three software complexity measures (Halstead's E, McCabe's u(G), and the length as measured by number of statements) were compared to programmer performance on two software maintenance tasks. In particular, the metrics suggested by Halstead, McCabe, and Woodward'et al, are reviewed. Traditionally, software metrics are generated by extracting. Three core requirements of this thesis are: 1) Measurement of code complexity for the code written in C. 2) Measurement should perform automatically on the code base and on a regular basis for new code releases.
