Size-oriented metrics focus on the size of the Coed party video and are usually expressed as kilo lines of code KLOC. Amazon Inspire Digital Educational Resources. There is also an issue with how software metrics are used. Thus, a enggineering software package could have two very different LOC counts depending on which counting method is used. While the process of defining goals, selecting metrics, and implementing consistent measurement methods can be time-consuming, the productivity gains and time saved over the life of a project make it time well invested.

Other objectives of using software metrics are listed below. Population is measured by calculating the total number of OO entities, which can be in the form of classes or operations. For example, if metrics values are used to represent a model for a software process, then metrics associated with the ratio scale may be preferred. The only operation that can be performed is to determine whether program 'X' is the same as program 'Y'. Advantages and Disadvantages of V Model. Most of the characteristics listed above are qualitative in nature. Model of computation Formal language Automata Software engineering metrics and models Computational complexity theory Logic Semantics. SMI can also be used as a metric for planning software maintenance activities by developing empirical models in order to know the effort required for maintenance. For analysis, comparison, and critical study of different programming language concerning their characteristics. The other has to do Software engineering metrics and models what we think, feel or sense as a result of the objective reality. Albrecht, A. Kitchenham and S. Web API. Van Nostrand,
A software metric is a measure of software characteristics which are quantifiable or countable.
- In recent decades software has become ubiquitous.
- In the context of software engineering , software quality refers to two related but distinct notions:.
- Once measures are collected they are converted into metrics for use.

These include errors detected while performing formal technical reviews and defects reported about various functions included in the software. Program volume V can be calculated by using the following equation. Algorithm design Analysis of algorithms Algorithmic efficiency Randomized algorithm Computational geometry. Value: Value of metrics should increase or decrease with the value of the software characteristics they represent. Project metrics serve two purposes. Bourque, P.

Here, we present the 3 types of metrics that you should be collecting. If you want more detail, our guide to measuring software quality tells you exactly which metrics are within each category and what levels are acceptable for each metric.
The three types of metrics you should collect as part of your quality assurance process are: source code metrics, development metrics, and testing metrics. These are measurements of the source code that make up all your software.
Source code is the fundamental building block of which your software is made, so measuring it is key to making sure your code is high-caliber. Not to mention there is almost always room for improvement. Look closely enough at even your best source code, and you might spot a few areas that you can optimize for even better performance.
Equally important is to track the percentage of comments within the code, which will tell you how much maintenance the program will require. The less comments, the more problems when you decide to change or upgrade.
Other things to include in your measurements is code duplications and unit test coverage, which will tell you how smoothly your product will run and at when are you likely to encounter issues.
These metrics measure the custom software development process itself. Gather development metrics to look for ways to make your operations more efficient and reduce incidents of software errors. Measuring number of defects within the code and time to fix them tells you a lot about the development process itself. Start by tallying up the number of defects that appear in the code and note the time it takes to fix them. If any defects have to be fixed multiple time then there might be a misunderstanding of requirements or a skills gap — which is important to address as soon as possible.
These metrics help you evaluate how functional your product is. There are two major testing metrics. The second part is a test of the testing itself. The more you measure, the more you know about your software product , the more likely you are able to improve it. Download The Ultimate Guide to Measuring Software Quality for a more detailed review of types of metrics, benchmarks and real-life case study.
