What is a good value for cyclomatic complexity?

For most routines, a cyclomatic complexity below 4 is considered good; a cyclomatic complexity between 5 and 7 is considered medium complexity, between 8 and 10 is high complexity, and above that is extreme complexity.

What is standard cyclomatic complexity?

Cyclomatic complexity (CYC) is a software metric used to determine the complexity of a program. It is a count of the number of decisions in the source code. The higher the count, the more complex the code.

What is the threshold for stable code as per cyclomatic complexity?

The minimum limit for cyclomatic complexity is 1….Values of cyclomatic complexity.

CC Type of procedure Risk
1–4 A simple procedure Low
5–10 A well structured and stable procedure Low
11–20 A more complex procedure Moderate
21–50 A complex procedure, alarming High

What is a good maintainability index?

85 and more: good maintainability. 65-85: moderate maintainability. 65 and below: difficult to maintain with really bad pieces of code (big, uncommented, unstructured) the MI value can be even negative.

What is the typical value of cyclomatic complexity for a code with less complexity?

Cyclomatic Complexity’s impact on your Software Quality Risk is assessed based on the provided value: 01 to 10 – Minimal Risk. 11 to 20 – Moderate Risk. 21 to 50 – High Risk.

How is cyclomatic complexity of code calculated?

Apply formulas in order to compute Cyclomatic complexity. 3) Cyclomatic complexity V(G) = P +1 V (G) = 2 + 1 = 3 Where P is predicate nodes (node 1 and node 2) are predicate nodes because from these nodes only the decision of which path is to be followed is taken. Thus Cyclomatic complexity is 3 for given code.

What are metrics of code quality?

Code quality metrics are a number of variables used to measure and determine if code is of high quality. Teams can then use those metrics for code review for changes, test coverage, and other actionable insights. Variables such as code complexity, portability, security, clarity, reusability, and others.

How is maintainability measured?

A common maintainability calculation is mean time to repair (MTTR). Mean time to repair (MTTR) is the most common measure of maintainability. It is the average time required to perform corrective maintenance on all of the removable items in a product or system.
