framework for technical software metrics

The eight stages of this product development framework include: When a form is designed, a list is prepared of all the items to be included on the form and the maximum space to be reserved. Chapter 15 Software Product Metrics - Software quality - A framework for product metrics - A product metrics taxonomy - Metrics for the analysis model - Metrics for the design model - Metrics for maintenance 2. This will help to improve decision making and the overall project success. Customer Problems 4. Each of the attributes can be subdivided into a set of further characteristics and will require tracking a whole set of metrics to get the real picture. a framework for "pulling together the range of (apparently) diverse topics which comprise 'software metrics"'. Measuring the satisfaction of the intended users is also of utmost importance. Clause 4 provides a framework for software quality metrics. Technical debt in one image source. According to ISO/IEC 25010, the quality of modern software can be described with eight main attributes – being delivered to requirements, reliability, maintainability, compatibility, portability, security, usability, performance. How to apply software development metrics? They are used to measur… It is worthwhile to establish a fundamental framework and a set of basic principles for the measurement of technical metrics for software. Quality and reliability of software. What does the availability depend on? Reduce overtime 5. In a paper that is reviewed later in the presentation, the researchers develop a general framework for evaluating a metric. … Interdependence 4. Software Technical Metrics Software Technical Metrics The metrics which help software engineers to gain insight into the design and construction of the products they build and the product itself.13 January, 2012 Mady By Utpal Ray 1 2. Continuous attention to technical excellence and good design enhances agility. Relying on the data, a project manager can better predict and plan budget, time, resources and requirements for upcoming iterations, as well as timely identify if an iteration or a whole project goes wrong. 2. Defect Density 3. In other words, tech leads are software engineers that enable the team to work with quality. Primarily, the project manager will be interested in tracking costs, resources, timelines and performance. Process Metrics:These are the measures of various characteristics of the software development process. This requires the ability to track a hierarchy of metrics. Quality metrics are an essential consideration with agile approaches. To accomplish this, a measurement model encompassing a consistent set of rules is required. Increase return on investment (ROI) 2. Software Size Measurement: A Framework for Counting Source Statements Author: Robert E. Park Keywords: software measurement, software size measurement, software metrics … Customer Satisfaction Chapter 15 software product metrics 1. Data can be gathered directly from end users through social network interactions (for products), survey forms, checklists, assessment questionnaires. CorporateMetrics is a conceptual framework for measuring market risk in the corporate environ-ment. These metrics can be computed for different stages of SDLC. He then sets out to establish such a framework in a series ofopening chapters presenting a scientific approach to the fundamentals of measurement, experimental design and analysis, software Instead, the team can be more focused on improvements of the already implemented releases based on user feedback). Be sure to DOWNLOAD the PDF version of this framework as all the white boxes are linked to Demand Metric tools & resources to help you execute the activities involved in this framework. In many software applications, a single data item triggers one or a number of information flows that effect a function implied by the trigg... System development life cycle is also referred as system study. Appointing a responsible person for metric tracking. Tutorial for Creating An Enterprise Metrics Framework Published: 03 October 2008 ID: G00161718 Analyst(s): Nigel Rayner Summary Most organizations don't have an enterprise metrics framework in place, yet it is key to success in business intelligence and performance management. But here's a deeper look at why these metrics are so critically important. As an example, for a real-time processing system, performance metrics will be a top priority, while for a distributed asynchronous system, metrics will center on availability. However, code lines differ in terms of complexity and functionality, and the number of comments in code can vary (it will increase in case of a distributed team or when code gets more complicated). Mean Time to Failure 2. After the list of important high-level software aspects to track is established, the right process of metrics implementation will run as follows: You can use available off-the-shelf formulas – among the most famous are Halstead’s Metrics, McCabe’s Cyclomatic Complexity, Albrecht’s Function Point Analysis. The role of metrics in software quality is well-recognized; however, software metrics are yet to be standardized and integrated into development practices across the software industry. To deal with this issue, in this paper, we propose a metric transfer learning framework (MTLF) to encode metric learning in transfer learning. • To build a catalogue of metrics using the framework. Before we start, let us make it clear that the list of metrics should be decided on individually each time. This means that the analyst must decide on the information-gathering tool and how it must be used. We should try to improve the system availability to retain the expected level of revenue. The data sources can also be project management tools, source control management systems, CI and CD tools, application performance management tools, BI tools. To power businesses with a meaningful digital change, ScienceSoft’s team maintains a solid knowledge of trends, needs and challenges in more than 20 industries. Yet there is a need to measure and control software complexity. CorporateMetrics Technical Document RiskMetrics Group What is CorporateMetrics? 14 software technical_metrics 1. Metrics can be used to improve software productivity and quality. Interaction 3 . We’ve already successfully undertaken 1850+ projects. Whether implemented as a Unfortunately, there’s no great framework to understand how great tech founders become world-class CTOs. Further in the text, we’ll discuss how to deal with this type of metrics in more detail. SLA monitoring and reporting, service adjustment. In the article, we explore the approach to designing and implementing effective metrics of both types. The framework is intended to provide some general forms of metrics such that defining a new metric basically means instantiating one or more of these forms to obtain the final definition. Software Quality Measurement: A Framework for Counting Problems and Defects September 1992 • Technical Report William A. Florac. Measurement assigns numbers or symbols to attributes of entities in the real word. It is a collaboration with Professor Bradley Fidler of the Stevens Institute of Technology, who studies the long-term evolution of network architectures from a social and institutional perspective. The Challenge of Technical Metrics Over the past three decades, many researchers have attempted to develop a single metric that provides a comprehensive measure of software complexity. Metrics that do not answer any concrete question of project stakeholders or the ones whose results don’t have any potential effect on the project process should be avoided. But many companies overlook positive behavioral metrics. Using software process metrics, software engineers are able to assess the efficiency of the software process that is performed using the process as a framework. These measures and the metrics derived from them can be used as independent indicators of the quality of analysis and design models. This provides opportunities to reconsider how we define and assess the quality of technical documentation. There are five types of characteristics for a system. Technical documentation is now fully taking the step from stale printed booklets (or electronic versions of these) to interactive and online versions. Software development metrics allow for a clear understanding of what and how teams have already done in the previous iterations of a project. I've already talked about the best metrics for data-driven software development, which include key performance … An experimental laboratory setup as 'Safety-Critical System' called Railroad Crossing Critical System (RCCS), which implements a safety-critical software, is used for demonstration and to validate the utility of the framework. There are mainly three types of system. Open or Closed 3 .Man Made Information System PHYSICAL OR ABSTRACT ... No two projects are ever the same. After that, they should proceed with a root cause analysis of each characteristic, moving to the actual data required to track the chosen aspect: “15 minutes of blocked functionality in our ecommerce solution can cost us up to $20 000 in lost sales. Metrics can help understand whether there is any value out of changing an approach, a practice, a tool, etc., what value exactly can be expected and how it correlates with investments put in. The ability of team to control quality is evaluated. To draw up an effective list of metrics, a PM or a QA engineer (in cooperation with a project owner and business stakeholders when needed) should think of the key success factors for software and the project process. Metrics are a good way to decide in which order the tasks should be performed to bring maximum value. What is the purpose of the measure? We handle complex business challenges building all types of custom and platform-based solutions and providing a comprehensive set of end-to-end IT services. Software development metrics allow for a clear understanding of what and how teams have already done in the previous iterations of a project. The number of failures, the duration of failures, the meantime to resume the service, etc.” – this is the right way to brainstorm the set of the needed metrics. It is used to assess the software size – and on this basis, estimate the efforts required to maintain software, a developer’s productivity and more. Interface consistency, the attractiveness of interactions, message clarity, interface element clarity, function understandability are examples of metrics suitable in both cases. 8 Software Development Models: Sliced, Diced and Organized in Charts, How to Outsource Application Management and Not Get Disappointed. LOC has long been a popular metric since it’s easy to measure and automate. Coming up with a mitigation plan in cases when metrics show unsatisfactory results. Organization 2 . Identifying the input data required for the measurement (and ensuring they’re available for tracking). Tracking all possible metrics requires significant input of effort and money. Clause 5 provides a methodology for software quality metrics, which is mandatory when applying this standard. Some metrics won’t need complex calculations and are, by their essence, a plain adaptation of measurement, for example, the number of features delivered over a sprint. Top 5 Software Metrics to Manage Development Projects Effectively What are Software Metrics? Business stakeholders are concerned with the external attributes (reliability, maintainability, etc.) Process Metrics: Process metrics pay particular attention on enhancing the long term process of the team or organisation. Also, the team may have to wait for other teams to complete their piece of work or lack proper communication with stakeholders regarding requirements specifications. On a more granular level, software development managers are trying to: 1. It is worthwhile to establish a fundamental framework and a set of basic principles for the measurement of technical metrics for software. With KPIs, a customer can clearly communicate and track the value they expect (an increase in the frequency of releases, improved test coverage, a reduced number of features waiting in the backlog longer than the deadline or a reduced number of defects found in user acceptance testing (UAT) / in production) from an outsourcing vendor and understand how productive outsourced teams are. Reduce costsThese goals ca… Deciding where to take the input data for measurements. 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 … It’s crucial to a good tech lead to ensure the success of delivered solutions. For example, testers can report on test coverage, test cases planned/executed and end users can provide info about problems they’ve encountered in interactions with software. For example, the efficiency of fault detection. Evaluating software packages: In this phase metrics are defined and weights are assigned to each basic attribute in the criteria hierarchy. When interpreting software development metrics, always take the context into account. The systems come with hardware, software and support. They lay out 10 points to check for, based on the IEEE software metric criteria. This is possible by collecting quality and productivity data and then analyzing and comparing these data with past averages in order to know whether quality improvements have occurred. The novelty of our proposed approach is that it can identify significant metrics using a combination of different filters and wrapper techniques. An ideal set of metrics is almost impossible to come up with in the first run; it rather evolves in the course of the project by trial and error. In our software development practice, we distinguish two types of software development metrics: those helping assess resulting software and those giving insights into the development process. Working valuable software that is sustainable means no shortcuts. Manage workloads 4. In MTLF, instance weights are learned and exploited to bridge the distributions of different domains, while Mahalanobis distance is learned simultaneously to maximize the intra-class distances and minimize the inter-class distances for the … Similarly, if a team delivers fewer new features than during previous iterations, it doesn’t necessarily mean that they are incompetent or less engaged. 1 .Physical or Abstract 2. It means code quality has to be good, and software is built in line with best practices for security and readability. Integration 5.... Software requirements can be mapped into various representations of the design model. Identify areas of improvement 3. of software. Also in this standard are four annexes that are included for illustrative and reference purposes only. Also, when metrics are applied in a consistent manner, it helps in project … We are a team of 700 employees, including technical experts and BAs. Cost per ticket is the best indicator of efficiency in service and support. Considering metrics in isolation is a bad practice. The framework considers measures that contribute to safety assessment through metrics in each of the Software Development Life Cycle phase. It’s part of the job to plan, design, lead, and execute technical solutions and improvements. For example, if user satisfaction score is low because of consistent dissatisfaction with the quality of updates that disrupt smooth functioning of software, it can be a signal to start dedicating more time in the course of an iteration to regression testing than to releasing a big bunch of new features. Fenton  notes this when he states: The spiral model suggests a framework activity that addresses customer communication. • To define a framework for formulating metrics over i* models. This 1992 report presents mechanisms for describing and specifying software problems and defects--two software measures used to understand and predict software product quality and software process efficacy. 2. The data can be provided by specific data owners. In this paper, we propose a software defect detection model that can be used to identify faulty components in big software metric data. So, if you base your productivity measurements on LOC exclusively, it’s highly possible that the results will be misleading. In today’s business there is more demand for computer services than there are resources available to meet the demand. Also, it is relevant to track such aspects as the Depth of Inheritance (DIT), Lack of Documentation (LOD), Response for a Class (RFC), and others. To improve any process, it is necessary to measure its specified attributes, develop a set of meaningful metrics based on these attributes, and then use these metrics to obtain indicators in order to derive a strategy for process improvement. As you see, quality attributes depend on multiple factors, and each will require a certain set of metrics that you’ll need to track to get the comprehensive information. The development teams, project managers and project owners want to know the quality of code they provide. The two important software characteristics are: 1. To blindly copy the metrics set from some other project, simply track everything a project management tool offers or a software development framework prescribes is an unreasonable waste of time and effort. This metrics include the following − 1. Leverage our all-round software development services – from consulting to support and evolution. Highly related metrics include the Lack of Cohesion in Methods (LCOM), Improvement of LCOM, and Tight Class Cohesion (TCC). This proposal was focused on developing a new metrics framework for security operation centers (SOCs) that measures and validates SOC performance against enterprise network security. The goal of tracking and analyzing software metrics is to determine the quality of the current product or process, improve that quality and predict the quality once the software development project is complete. Software metrics help project managers to gain an insight into the efficiency of the software process, project, and product. Aggregate score is then calculated for each software package. And if a single value of this quality metric is difficult to derive, it should be possible to develop measures of different internal program attributes (e.g., effective modularity, functional independence, and other attributes ). Today, selecting a system is a serious and time-consuming business. Relying on the data, a project manager can better predict and plan budget, time, resources and requirements for upcoming iterations, as well as timely identify if an iteration or a whole project goes wrong. ScienceSoft is a US-based IT consulting and software development company founded in 1989. Let’s take reliability as an example. Rating is done against each basic criterion in hierarchy for each software package considered for detailed evaluation. Metrics give the project owner a possibility to quickly understand and assess the project state, problems and how they are being resolved. For a public product, it’ll be a customer satisfaction score, while for internal applications, assessments will be based on employee feedback. They also need to understand the efficiency of the development processes established. Tech Leads are responsible for managing technical aspects of software development flow in a specific context or team. For example, when switching to DevOps, such KPIs as the number of failed changes/deployments and mean time to recovery (MTTR) can help to assess the improvements that come with a change. Project owners, project managers, development and QA teams may turn to software development metrics for: Measurement is a cornerstone of management. 6. Deciding with whom the results should be shared (for whom the received data will bring value). Thus, team leads, architects and developers are interested in KPIs that can shed light on the technical part of the project, such as algorithmic complexity, the number of unnecessary dependencies, code churn, code duplication, test coverage, defect density and alike. Software metrics can be classified into two types as follows: 1. One of its characteristics resides in software maturity. 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. How to interpret software development metrics? Product Metrics:These are the measures of various characteristics of the software product. The measurement framework acts as the road map; the business’s goals and objectives are the destination, critical success factors provide the directions, and metrics provide the sign posts to keep you on course. But here again, problems arise. A vendor, in their turn, can vividly present the improvements that have been delivered. ! The right metrics provide insights into what the organization needs to change and where it is winning. Software Metrics provide a quantitative and qualitative basis for the development and validation of models of the software development process, thus they are a valuable entity in the entire software life cycle. , timelines and performance text, we explore the approach to designing implementing.
