A software metric is a standard of measure of a degree to which a software system or process possesses some property. Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms.
What is software metrics and why?
A software metric is a measure of software characteristics which are measurable or countable. Software metrics are valuable for many reasons, including measuring software performance, planning work items, measuring productivity, and many other uses.
What are the major limitations of software metrics?
Disadvantages. It is not easy to apply metrics in all cases. It is difficult and expensive in some cases. It is difficult to verify the validity of historical or empirical data on which the verification and justification.
What are the two types of software metrics?
There are 2 types of software measurement:
- Direct Measurement: In direct measurement the product, process or thing is measured directly using standard scale.
- Indirect Measurement: In indirect measurement the quantity or quality to be measured is measured using related parameter i.e. by use of reference.
Why do we need metrics in software quality?
Software Testing Metrics are useful for evaluating the health, quality, and progress of a software testing effort. Without metrics, it would be almost impossible to quantify, explain, or demonstrate software quality.
Why is software quality metrics important?
Metrics serve as important indicator of the efficiency and effectiveness of software process. Analysis of defined metrics helps identify area of improvement and devise subsequent actions. Software metrics act as indicators and provide information so people can make more informed decisions and intelligent choices.
