Software Quality Metrics - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Within the software development process, many metrics are that are all connected. Information technology - Software quality characteristics & metrics - Part 1: Quality characteristics and subcharacteristics. 2.Process metrics − These characteristics can be used to improve the development and maintenance activities of the software. Software Quality Engineering - . a set of measures of development progress (e.g. Software metrics have been proposed for measuring many, many different aspects of an existing body of source code. In a paper that is reviewed later in the presentation, the researchers develop a general framework for evaluating a metric. Identify. We can accurately measure some property of software or process. Software Metrics. Without these types of metrics, organizations will simply attempt their transformation blindly, with limited capacity to show results, including the business outcomes demanded of today's technology organizations. Software Quality Assurance (SQA) is simply a way to assure quality in the software. It helps the team to keep a track on the software quality at every stage in the software development cycle and also provides information to control and reduce the number of errors. With advances in hardware, Cumulative data will also be presented to provide a status of process and product repeatability. 2. They lay out 10 Software Metrics Product vs. process Most metrics are indirect: No way to measure property directly or Final product does not yet exist For predicting, need a model of relationship of predicted variable with other measurable variables. Within the software development process, there are many metrics that are all related to each other. Top 5 software quality metrics. These standards describe the structure and presentation of documents. number of model revisions) or as a combination of internal quality and external quality (e.g. Schedule of the software project on the whole. 2. Software metrics to measure software quality over time. Basically, as applied to the software product, a software metric measures (or quantifies) a characteristic of the software. Software Quality Metrics. software metrics-ii. Agile Quality Metrics. It is the set of activities which ensure processes, procedures as well as standards suitable for the project and implemented correctly. This may be the most popular definition in the software quality community and traces to Philip Crosby. View Software Metrics.ppt from CS 494 at Kinnaird College for Women, Lahore. Devise actions to improve quality of the software – Process improvements • Process Performance improvements => Product Productivity improvements – Product improvements 4. 3.4-2 quality metrics summary 81 3.4-3 quality criteria definitions 83 5.1-1 sqm based on halstead's family of software metrics 128 5.1-2 quality factor correlations 129 5.2-1 sqm based on mccabe's cyclomatic complexity metric 132 5.3-1 software quality factor definitions and rating formulas 135 Software metrics play an essential part in understanding and controlling the overall software engineering process [2]. metrics are measures to provide feedback to the Software Quality - . Several daily, weekly, or annual progress reports in single slide view are known as dashboard templates. Conformance to wrong requirements is not quality. The goal of software testing metrics is to improve the efficiency and effectiveness in the software testing process and to help make better decisions for further testing process by providing reliable data about the testing process. The Modern Metrics PowerPoint Dashboard provides several data drive charts and graphs. These data representation graphs are useful for various business analysis, research, and statistical reports. Software Quality Metrics Software metrics can be broadly classified into process, product and Project metrics. The ability of team to control quality is evaluated. A software metric is a measure of software characteristics which are measurable or countable. Software Quality metrics Software metrics can be classified into three categories − 1.Product metrics − Describes the characteristics of the product such as size, complexity, design features, performance, and quality level. Project metrics to assess a software development project’s health and the productivity of the teams involved (development team, UX designers, QAs, support team). Top 5 Software Metrics to Manage Development Projects Effectively What are Software Metrics? Software metrics are important for many reasons, including measuring software performance, planning work items, measuring productivity, and many other uses.. applied throughout sw engineering process encompasses analysis, design, coding, testing, tools ! In this article, we focus on software metrics that we often use in our outsourced software development projects. Escaped Defects will help you identify the number of bugs in a build or release after in enters production. Metrics have, in fact, a number of interesting characteristics for providing evolution support [11]. Three assumptions (Kitchenham) 1. Software quality is conformance to requirements. For software products, the fitness of use is generally explained in terms of satisfaction of the requirements laid down in the SRS document. Classification of Software Metrics: There are 2 types of software metrics: Product Metrics: Product metrics are used to evaluate the state of the product, tracing risks and undercovering prospective problem areas. Quality of the software, different metrics look at different aspects of quality, but this aspect deals with the code. Software quality metrics are a subset of software metrics that focus on the quality aspects of the product, process, and project. ... Software metric is a measurement that relates to any quality attributes of the software system or process. In this document we discussed various software quality metrics falling under each category with the importance. In some organization in process quality metrics means tracking defect arrival during formal machine testing as well as it cover various parameters in each phase of the development cycle. Software testing metrics provide quantitative approach to measure the quality and effectiveness of the software development and testing process. Software Quality Assurance(SQA) Software Quality Assurance is the set of activities which ensure that the standards, processes and procedures are suitable for the project and implemented correctly. Software metrics can, particularly, be used to analyze the evolution of the quality of software systems [10]. Software Quality. It is less formally defined than end product metrics and their practices. software metrics. Introduction Software metrics can be classified into three categories • Product metrics • Process metrics • Project metrics Product metrics describe the characteristics of the product such as size, complexity, design features, performance, and quality level Process metrics can be used to improve software development and maintenance. Some common software metrics (discussed later) are:- … For example, a direct final metric for the factor reliability could be faults per 1,000 lines of code (KLOC) with a target value—say, one fault per 1,000 lines of code (LOC). It seems so obvious and straightforward until you realize it leaves out the quality of the requirements. In this chapter from his book on software quality engineering, Stephen H. Kan discusses several metrics in each of three groups of software quality metrics: product quality, in-process quality, and maintenance quality. Monitor Quality during development Software development metrics are quantitative measurements of a software product or project, which can help management understand software performance, quality, or the productivity and efficiency of software teams. This group of agile software development metrics will help you assess the quality of your software product and predict whether the target audience will like it. He also describes the key metrics used by several major software developers and discusses software metrics data collection. Escaped Defects. In general, software quality metrics are more closely associated with process and product metrics than with project metrics. Depending on the presentation method the dashboard trigger different kind of decisions at each studied company. In process quality metrics means individual stages, rather than the final testing stage. Process Metrics: The second step is to identify the software quality metrics by decomposing each factor into subfactors and those further into the metrics. His teams managed to achieve a 25% annual increase in code quality and 100% increase in throughput by re-defining software quality based on the following metrics… Deviations of actual timetable and budget performance from planned. Software metrics are valuable for many reasons, including measuring software performance, planning work items, measuring productivity, and many other uses. Define what quality means for large software systems 2. Some of these metrics, such as Lines of Code and Comment Ratio, have a fairly obvious meaning and use; most are less self-explanatory. Certain software quality attributes such as maintainability, usability, reliability cannot be exactly specified and measured. Managing Software Quality 1. Here are the top five quality metrics … complexity and number of defects). This part provides the concepts introduced in the original standard is a recommended quality model which categorizes software quality in six characteristics, which are further sub - divided into subcharacteristics. Software quality product is defined in term of its fitness of purpose. Software Testing Metrics are the quantitative measures used to estimate the progress, quality, productivity and health of the software testing process. Measure Quality of a complete or partial system 3. The following are some of the most significant and useful software metrics of the latter type. The software metrics that the quality assurance (QA) team procedures are connected with the test activities that are part of test phase and so are formally known as s oftware testing Introduction to Quality Metrics - 1 1 The software industry is in a constant state of change. Metrics should not depend on any programming language. In this Ppt, Software Quality Metrics are discussed This chapter is structured as follows. That is, a quality product does precisely what the users want it to do. Quality - Quality of the software is checked to see if it meets the requirements, expectations and demands of the customer and free from defects. Analyzing the Software Quality Metrics for Object Oriented Technology. The QMR will consist of a presentation of all quality metrics and specifications measurements and a comparison to previous prototype iterations to show progress. A definition of software quality metrics is:- A measure of some property of a piece of software or its specifications. A software metric is a measure of software characteristics which are quantifiable or countable.
