Rule Definition
Cyclomatic Complexity is a measure of the complexity of the control structure of an Artifact. It is the number of linearly independent paths and therefore, the minimum number of independent paths when executing the software. The effort and time for diagnosis of deficiencies or causes of failures, or for identification of parts to be modified is directly related to the number of execution paths, i.e. the complexity of the control flow.
Analyzability declines with increasing Cyclomatic Complexity.
Each modification must be correct for all execution paths. Cyclomatic Complexity computes the number of the linearly independent paths, a lower bound of all execution paths ignoring multiple iterations.
Remediation
Reduce the number of decision points included in the artifact.
