Top 5 software quality metrics. Here are the top five quality metrics that really matter: 1. Committed stories vs. Delivered results meeting 'doneness' criteria. Remember the last time someone committed to do something for you and either failed to deliver or didn't meet your standards? It caused delays and rework, along with a lot of frustration.

A Software DEFECT / BUG is a condition in a software product which does not meet a software requirement (as stated in the requirement specifications) or end-user expectation (which may not be specified but is reasonable). Software testing metrics - Improves the efficiency and effectiveness of a software testing process. Software testing metrics or software test measurement is the quantitative indication of extent, capacity, dimension, amount or size of some attribute of a process or product. Example for software test measurement: Total number of defects.
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. Since quantitative measurements are essential in all sciences, there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective, reproducible and quantifiable measurements, which may have numerous valuable applications in schedule and budget planning, cost estimation, quality assurance, testing, software debugging, software performance optimization, and optimal personnel task assignments.

Software Testing Metrics and measurements are very important indicators of the efficiency and effectiveness of software testing processes. Learn with examples and graphs how to use test metrics and measurements in software testing process.
Common software measurements[edit]
Common software measurements include:
Limitations[edit]
As software development is a complex process, with high variance on both methodologies and objectives, it is difficult to define or measure software qualities and quantities and to determine a valid and concurrent measurement metric, especially when making such a prediction prior to the detail design. Driver 2 free download. Another source of difficulty and debate is in determining which metrics matter, and what they mean.[3][4]The practical utility of software measurements has therefore been limited to the following domains:
Craigslist auto poster software program. A specific measurement may target one or more of the above aspects, or the balance between them, for example as an indicator of team motivation or project performance.
Acceptance and public opinion[edit]
Some software development practitioners point out that simplistic measurements can cause more harm than good.[5] Others have noted that metrics have become an integral part of the software development process.[3]Impact of measurement on programmer psychology have raised concerns for harmful effects to performance due to stress, performance anxiety, and attempts to cheat the metrics, while others find it to have positive impact on developers value towards their own work, and prevent them being undervalued.Some argue that the definition of many measurement methodologies are imprecise, and consequently it is often unclear how tools for computing them arrive at a particular result,[6] while others argue that imperfect quantification is better than none (âYou canât control what you can't measure.â).[7]Evidence shows that software metrics are being widely used by government agencies, the US military, NASA,[8] IT consultants, academic institutions,[9]Gamma world pdf free. and commercial and academic development estimation software.
