What is a good maintainability index?
Table of Contents
I have come across the recommended values for a Maintainability Index (MI) as follows: 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.
How is maintainability index measured?
The maintainability index is calculated as a factored formula consisting of SLOC (Source Lines Of Code), Cyclomatic Complexity and Halstead volume. It is used in several automated software metric tools, including the Microsoft Visual Studio 2010 development environment, which uses a shifted scale (0 to 100) derivative.
What is maintainability index in code metrics?
Maintainability Index – Calculates an index value between 0 and 100 that represents the relative ease of maintaining the code. A high value means better maintainability. Color coded ratings can be used to quickly identify trouble spots in your code.
What is Halstead volume?
The Halstead Volume is based on the Length and the Vocabulary. Halstead Volume (VOL) is: LTH * log2(VOC)
How do you read metrics results?
Right-click -> “Calculate Code Metrics.” Once you run the code metrics, Visual Studio will analyze the selected project/projects and display the code metrics results in the “Code Metrics Results” window. From the result window, you can drill down to each and individual method to analyze their metrics data.
What is a KPI metric?
What are KPIs? KPIs or Key Performance Indicators are the metrics by which you gauge business critical initiatives, objectives, or goals. The operative word in the phrase is “key,” meaning they have special or significant meaning. KPIs act as measurable benchmarks against defined goals.
What is Halstead software metrics?
According to Halstead’s “A computer program is an implementation of an algorithm considered to be a collection of tokens which can be classified as either operators or operand.”
What is Halstead effort?
Halstead effort is one of a number measurements developed by Maurice Halstead to determine the mental effort required to develop or maintain a program. The lower a program’s Halstead effort, the simpler the program is to change.
What are testing metrics?
Software Testing metrics are quantitative steps taken to evaluate the software testing process’s quality, performance, and progress. This helps us to accumulate reliable data about the software testing process and enhance its efficiency.
