The Process and Product Quality Assurance process area supports the delivery of high-quality products by providing project staff and managers at all levels with appropriate visibility into, and feedback on, processes and associated work products throughout the life of the project. This encompasses numerous data processing transactions, services, or threads of behavior. Therefore, a potential MCDA technique must address decision problems where a finite set of alternatives is considered. Research on traditional quality models has been carried out in more recent years. The software design must be sensitive to the impact of resource utilization on performance objectives. Therefore, a potential MCDA method must address the sorting problématique in order to be applicable for SQA purposes. Resolving assumptions. 2. Figure 10.1. Traveling. This feature of management is aimed to secure the attributes of the engineering process. This correspondence is typically not considered explicitly by the method’s intended users, but arises from the definition of the problem. The process of developing a software product using software engineering principles and methods is referred to as software evolution.This includes the initial development of software and its maintenance and updates, till desired software product is developed, which satisfies the expected requirements. Software data processing transactions involve many analytical combinations and permutations that are difficult to comprehend. The process of software engineering converts and transforms high level stated needs into an end product through various intermediate software artifacts such as requirements, use cases, design diagrams, code, test cases, and so on. Quality Control: Quality Control involves a series of inspections, reviews, and tests used throughout the software process to ensure each work … ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Quality management and Software Product Quality Engineering. Example assumptions include preference independence, difference independence, value independence, and preference transitivity. Mean Time to Failure 2. It is the set of activities which ensure processes, procedures as well as standards suitable for the project and implemented correctly. However, MCDA methods typically do not make this assumption. The physical architecture identifies and specifies the structural software elements that will be elaborated (designed, coded, integrated, and tested) during software implementation. The Strauss–Corbin approach focuses on coding paradigms and in systematic categorization and analysis of the collected data to uncover the relevant factors behind observed phenomena, whereas the Glaserian approach focuses on passive observation and emergence of strong codes from the data which then can be used to identify the relevant factors. In other words, some problem-intrinsic constraints are not subject to trade-offs, and not fulfilling them cannot be compensated by any positive characteristic of the method, thus automatically disqualifying its use for the purpose of SQA. The Grounded Theory method allows the research question freedom to explore the phenomenon in depth, and allows a broader viewpoint on the topic than quantitative approaches. Quality control popularly abbreviated as QC. (2010), to usability by Winter et al. Maintainability can be defined as the ease with which a software product can be modified to correct errors, to meet new requirements, to make future maintenance easier, or adapt to the changed environment. [13] and [17]. Such a question may be, for instance, “Does the relative importance of the quality aspects security and reliability change if the usability aspect is evaluated as being bad instead of good?” For instance, in the context of good software usability, security is considered more important than reliability, whereas in the context of bad usability, reliability is considered more important than security. Functional analysis and allocation is employed to achieve the following six fundamental design challenges confronting software product quality. It is generalized by Wagner and Deissenboeck (2007) and Lochmann and Goeb (2011), applied to security by Luckey et al. Software Quality Engineering involves complete software development process just to ensure that that any agreed-upon processes, standards and procedures are being followed to get desired results and there should be no cherry picking of standards An appropriate analysis should be performed and presented to the quality experts and quality stakeholders, who should be aware of potential consequences of dependent quality aspects. Underlying axiomatic assumptions: Axiomatic assumptions with respect to decision criteria. For example, using certain mathematical operations for assessing quality (which is defined by means of multiple quality attributes) requires these attributes to be orthogonal to each other. Design complexity directly translates into code intricacy and obscurity. This is significant in software development as some product quality attributes are hard to assess. The complicated relationships between various quality attributes can be represented by multiple links between the nodes. Al-qutaish (2010) studied five hierarchical quality models, which are the McCall model, the Boehm model, the Dromey model, the FURPS model (Grady, 1992), and the ISO 9126 model. (2009) applied ontology extraction and analysis techniques to the definitions of software product quality attributes. It requires Technical and Managerial skills. Possible options include a finite or an infinite number of criteria. Software Process Model: A software process model is an abstraction of the actual process, which is being described. This metrics include the following − 1. Project managers have a wide variety of metrics to choose from. In 2011, Deissenboeck et al. (2008), to service-oriented architecture by Goeb and Lochmann (2011), and combined with Bayesian network to assess and predict software quality by Wagner (2010). Maintainability: In software engineering, software maintenance is one of the most expensive and time-consuming activities. 3. It comprises three aspects outlined below. They studied 67 most commonly discussed software product quality attributes and concluded that there is a lack of consensus on the concepts and terminologies used in this field. In the software industry, for example, people commonly call them quality assurance engineers. Data processing efficiency and effectiveness depends on the regulation of computing resource utilization. The concept of achieving a balance among product requirements, product architecture, sustainment processes, and project objectives is supported by the conduct of trade-off analysis and risk assessments. Quantity of alternatives: The number of decision alternatives considered. The objective of quality assessment (i.e., assigning a value of quality to a software product) corresponds to the sorting problématique (β) in the MCDA domain. (2011) and Wagner et al. As defined in ISO/IEC 15504-1 Concepts and Vocabulary [9], an organization unit is a part of an organization, which deploys one or more processes with coherent processes context and operates within a coherent set of business goals. However, the feasibility of the latter strategy might be very limited in the software engineering context, which is known for the scarcity of measurement data. Richard F. Schmidt, in Software Engineering, 2013. Software Quality Defect Management Approach Assumptions that are not challenged and resolved may result in a software product that does not effectively satisfy customer needs and expectations. The functional architecture provides a working view of the software product with no physical or structural features. Products should satisfy customer needs faster (time-to-market). This assumption is typically either met or relatively easy to ensure in the context of software quality assessment. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Any software process must include the following four activities: 1. Typical examples of activities are attacking the system related to system's security and modifying the code of a class related to the modifiability. Simplifying the solution. These are metrics that pertain to Process Quality. In order to identify these constraints, we investigated the correspondence between the basic characteristics of MCDA methods defined in [35] and the inherent characteristics of an SQA problem. Throughout the software engineering process the emphasis of verification and validation is to ensure that the software product architecture definition will satisfy stakeholder needs and expectations. Functional analysis provides the means for identifying the myriad of possible data processing sequences the software must facilitate. In addition to organization model, ISO/IEC 15504-1 [9] was applied to define the fundamental concepts for process improvement, as this standard offers an assessment model for organizational processes defined in the ISO/IEC 12207. Determining resource utilization. Once they are satisfied with the design, you create beautiful cards and ship them quickly, for a great price. Software quality metrics can be divided further into end-product quality metrics and in-process quality metrics. You just applied the principles of software e… More importantly, our method covers the model construction process and automated analysis of the models, while their work does not. However, there Ans: Software Process and Product Metrics are quantitative measures of-They are a management tool. In the preliminary phase, Strauss–Corbin was applied on the analysis of the existing data because of its codification method, which allowed detailed and structured analysis on the collected qualitative data set. … Your customers are happy and you are too. The term stakeholder is used to represent all customers of the technical effort, including project management, customers, end users, suppliers, and product sustainment organizations. The concept of conducting the study by using some form of action research (e.g., [64]) was rejected as the possibility of affecting the organizations and studying the effect of the changes, which forms the core of the action research approach, was limited. Language, which is used to communicate and express requirements, involves imprecise, vague, unclear, ill-defined, inexact, nebulous words and expressions. There are two main approaches to software quality: defect management and quality attributes. In the context of SQA, a finite number of alternative software products can be considered at a time. Software development requires a complex web of sequential and parallel steps. Description. This chapter outlines the approach through a set of principles, wherein each principle focuses on systematic achievement of a specific quality engineering concern and contributes to the quality assurance of software systems in a consistent manner. Some factors that influence quality and productivity are: 3. Using such operations upon a QM that includes interdependent quality attributes would lead to meaningless quality assessments. Performance measures at the software product level must be allocated to provide lower-level design aspirations. Preference transitivity: For three alternative software products a, b, and c, the following condition is satisfied: If a is preferred to b and b is preferred to c, then a should be preferred to c. This assumption corresponds to what we expect in practice when assessing the quality of software products. This will require extensive user training and may dissuade potential customers from adopting the software product as an institutional standard. It’s Quality and Productivity depends on the processes which develop and maintain those software products. Customer Problems 4. The essence of software quality engineering is to investigate the relationships among in-process metrics, project characteristics, and end-product quality, and, based on the findings, to engineer improvements in both process and product quality. These activities may involve the development of the software from the scratch, or, modifying an existing system. However, there is a ve Therefore, a potential MCDA method must address decision problems with a finite set of decision criteria in order to be applicable for SQA purposes. Basic problématiques are: sorting, ranking, and choice. The user interface design and user interactions must not be convoluted. software engineering is the the management of different phases in SDLC to give a quality product. This tenant of IPPD identifies four central themes for establishing a quality software product: Customer needs should determine the nature of the software product and processes. In addition to the process models for development and testing, the definition of software quality was taken from the standard ISO/IEC 25010 Software product Quality Requirements and Evaluation quality model [8] to enable the study to assess the output of the research subjects. Yet, some MCDA methods do not satisfy this axiom when combined with particular synthesis approaches. What is Software Quality? In smaller organizations, the organizational management operates within the OU or is directly above it. After which developers create a prototype of the intended software and show it to the users to get their feedback at the early stage of software product d… (2007) for the quality of maintainability. These constraints can be considered as necessary criteria for accepting or rejecting a candidate MCDA method. Software quality management is the answer when the question of how to improve software quality of the product is posed. In Grounded Theory [63], the objective of the research is to present an accurate description of what is being studied, and by methods of reduction and generalizations to build a believable descriptive narrative and chain of evidence from observations to a descriptive model with little or no interpretation on the studied phenomenon [56]. Value (score) independence: For each pair of quality aspects, their values are uncorrelated. The software engineering process, discussed in the Software Engineering Process KA, influences the quality characteristics of software products, which in turn affect quality as perceived by stakeholders. Our case study shows that such a quality modeling approach can represent complicated quality models of real software system adequately. Quality Engineers focus on optimizing product quality which W. Edwards Deming defined as: Quality = Results of work efforts Total costs. The triangulation of data in research means application and comparison of several types and sources of data to further validate the results. Although the Glaserian approach is also a merited and appropriate method, the practical limitations and applicability in our research context made the Strauss–Corbin more suitable for the study purposes, and therefore it was applied throughout the research process. Software quality management is a management process that aims to develop and manage the quality of software in such a way so as to best ensure that the product meets the quality standards expected by the customer while also meeting any necessary regulatory and developer requirements, if any. The functional architecture is complete when every functional component, unit, and interface has been specified. Rank reversal refers to a situation where the rank order of alternative products with respect to their quality may change after the set of alternative products is increased by simply adding copies of original products. This constraint disqualifies all MCDA methods that address continuous (optimization) decision problems, which handle an infinite space of potential decision alternatives. Functional analysis accentuates the existence of incomplete or inconclusive information to draw attention to suppositions that are not substantiated. In addition to the process models for development and testing, the definition of software quality was taken from the standard ISO/IEC 25010. The weaknesses of such quality models discussed in section “Related works and open problems” have been addressed successfully in our graphical quality modeling approach. The reason to apply OUs as an assessment unit instead of entire corporations or projects was to normalize the differences between the organizations, and minimize the effect of different objectives and business goals, and to enable direct comparison between research subjects. Product is like a destination. It is a Software Engineering process used to ensure quality in a product or a service. In general, MCDA relies on the assumptions that a decision maker (1) is rational, (2) does not change his/her preferences, and (3) has sufficient knowledge to make consistent judgments [34]. In this study, the qualitative data collected with the interviews and quantitative data collected with survey enabled the comparison between the data sources and was applied to further validate the results, as demonstrated in Refs. Yet, at least some of the problem-intrinsic constraints determine the feasibility of using an MCDA method for the purpose of SQA. For example, Barron and Barrett [4] point out that in the context of MCDA methods with an additive aggregation model, strong positive correlations among attributes generally reduce the sensitivity for attributing weights, and strong negative correlations increase this sensitivity. The objective of functional analysis and allocation is to formulate a complete, consistent, and verified functional architecture that conforms to the specified software requirements. Achieving performance objectives. Software organizations which develop and maintain software systems on an industrial scale, have huge challenges in addressing software product quality concerns in terms of identifying a comprehensive set of software quality requirements and ways to achieve them in spite of adoption to industry standard quality systems and processes. Functional analysis ensures that every function is clearly specified so that no misunderstanding exists in the description of the functional solution. Software Quality Assurance (SQA) is simply a way to assure quality in the software. Software Quality Assurance. If a QAx exists for which the preference between QA1 and QA2 changes for different values of QAx, then QA1 and QA2 are preferentially dependent. Kayed et al. Techniques used in particular MCDA methods make certain assumptions regarding input information. Basic structures include: set, hierarchy, and network. At the uppermost layer it identifies the principal software functions that interact with external entities to describe the software response to external stimuli. Padmalata V. Nistala, ... Anand Kumar, in Software Quality Assurance, 2016. Therefore, software quality decision makers must meet these assumptions in order for an MCDA method to provide a meaningful quality assessment. Quality Glossary Definition: Software quality assurance (SQA) Software quality is defined as a field of study and practice that describes the desirable attributes of software products. This definition was expanded in the testing-related processes with the test process model defined in the ISO/IEC 29119 test standard [7], which defines the organization and process activities from the viewpoint of testing. Defect Density 3. The software architecture must identify every data processing task, including failure detection, remediation actions, and consequential degraded modes of operation. It should be a part of the quality modeling process. The survey method is an appropriate method to collect data from a standardized group of personnel, such as software development professionals namely software project leaders and test managers. Clarifying ambiguity. Possible options include a finite or an infinite number of alternatives. https://doi.org/10.1016/B978-0-12-802301-3.00006-5. A practical way of checking preferential dependence is to ask the decision maker for each criterion whether the preference scores of an alternative to one criterion can be assigned independent of knowledge about the preference scores of all the other criteria. The increased complexity and scale of software systems presents difficult challenges in design, development, and asserting software quality. This chapter outlines the approach through a set of principles, wherein each principle focuses on systematic achievement of a specific quality engineering concern and contributes to the quality assurance of software systems in a consistent manner. Intrinsic constraints of MCDA refer to the mutual correspondence between a potential MCDA method and the basic characteristics of the software product quality assessment problem. On selection of the Grounded Theory, the second decision was then between the disciplines of Glaserian (outlined in Refs. Software Engineering Assignment Help, Explain process and product quality, Explain Process and product quality The quality of a developed product is influenced by the quality of the production process. Therefore, the issue of correlated quality aspects should be considered explicitly during quality modeling—thus already before quality assessment is applied. Quality assurance is the process of defining how software quality can be achieved and how the development organization knows that the software has the required level of quality. Software specification(or requirements engineering): Define the main functionalities of the software and the constrains around them. Complexity is never a desirable characteristic of any software product. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V.

Nistala, ... Anand Kumar, in, Relating System Quality and Software Architecture, applied ontology extraction and analysis techniques to the definitions of, The functional analysis and allocation practice provides an approach for transforming software requirements into the functional transactions that the software product must enable. The type of decision problem handled by a potential MCDA method must correspond to the type of decision problem represented by the software product quality assessment. The Grounded Theory method was selected as an analysis method in the preliminary phase of the study, as the nature of the research topic and the existing data were considered too broad and unstructured for quantitative analysis. The functional analysis and allocation practice provides an approach for transforming software requirements into the functional transactions that the software product must enable. I said point B. Process quality is one of a number of contributors to product quality. In this approach, the quality of the system is manifested by how facts affect activities, where the impact of a fact on an activity can be either positive or negative depending on whether the fact contributes to the action positively or negatively. Software sustainment costs will increase in proportion to the complexity of the design. Products should satisfy customer needs better (improved quality). Elementary functions are labeled functional units and must be specified to support the structural design of the software product. Software quality managers require software to be tested before it is released to the market, and they do this … An evaluating of the Quamoco meta-model and the tool was reported in Klas et al., (2011). While the operational model describes the role of the software product in executing a business or operational process, the functional architecture explains the data processing actions the software product must perform. Concepts: Process Quality. However, we further include phenomena as an important part of quality models. According to the literature [68,69], the combination of quantitative and qualitative methods is usually more beneficial than applying either approach separately: statistical relationships found between the quantitative variables can be verified against qualitative data and vice versa. The functional architecture represents a comprehensive, integrated set of data processing transactions. Figure 10.1 addresses the role of the functional architecture as the initial step in the translation of software requirements into a design for the software product. Customer Satisfaction Basic MCDA characteristics establish the boundaries beyond which the method cannot be used. Example assumptions that are often made by MCDA methods include preference independence, value independence, difference independence, and preference transitivity [30]. By continuing you agree to the use of cookies. Let's imagine you're running a successful business creating handmade cards, where customers can place orders detailing their specifications. Elaborating a solution. In addition to the qualitative study using the Grounded Theory approach, quantitative data were collected from a survey [57]. The 1-year Process Quality Engineering Ontario College Graduate Certificate at Conestoga College provides the knowledge and techniques to improve the delivery and quality of products and services focusing on the achievement of performance excellence through the use of modern quality … It is unrealistic to assume and hardly feasible to ensure correlation independence in the context of software quality assessment. In the main data collection and analysis phase, the Grounded Theory method was applied as it suited the purposes of the study as the research topic, test processes in organizations, was considered a large and broad topic. They are used to measure the efficiency and effectiveness of various processes. However, according to the CHAOS2 reports for a period of 15 years, the success rate for software development projects hovers around 28%, an average of 37% of the projects were considered challenged,3 and the remaining 35% were impaired.4 Therefore, one can surmise that the current methodologies, tools, and techniques for software development are not adequate to fulfill this tenet of IPPD. Type of the decision problem: The problématique addressed in the decision problem. Evolution starts from the requirement gathering process. Adam Trendowicz, Sylwia Kopczyńska, in Advances in Computers, 2014. How to obtain and use such quantitative data in the analysis of software architecture is the key problem to be solved. The increased complexity and scale of software systems presents difficult challenges in design, development, and asserting software quality. Quality assurance focuses on maintaining quality in the production process, while quality engineers ‘engineer’ it. Functional analysis can be used to speculate about and evaluate assumptions, thereby eliminating judgment or opinions as the basis for product design. On the other hand, user requirements on SQA will typically represent sufficient criteria, meaning that poor performance of an MCDA method with respect to some requirements can be compensated by its good performance concerning other requirements. Specified performance requirements or objectives must be comprehended and the software product designed to achieve these criteria. In other words, quality engineers devise the system. Products should satisfy customer needs at lower cost (reduced product and life-cycle costs). These are metrics that relate to Project Quality. They are determined by the assumptions and hypotheses on which the whole theoretical and axiomatic development of an MCDA method was based and encompass: Structure of the decision model: The structure in which the decision criteria are organized. If methodologies or approaches to software development were sufficient to fulfill these mandates, then there would be no need for further research or rhetoric about improving software development. An activity is an action that can be performed on or with the support of the system under consideration. Delayed Delivery: Software takes longer than the estimated time to develop, which in turn leads to cost shooting up. Software Quality: Software Quality is defined as the conformance to explicitly state functional and performance requirements, explicitly documented development standards, and inherent characteristics that are expected of all professionally developed software. Software Quality Management. Hong Zhu, ... Yanlong Zhang, in Relating System Quality and Software Architecture, 2014. Difference independence of quality aspects is typically fulfilled in the quality assessment context and thus does not actually need to be tested. Copyright © 2016 Elsevier Inc. All rights reserved. The main difference between the activity-based approach and our approach is that we emphasize the relationships between quality-carrying properties while the activity-based approach is concerned with how such properties affect the actions to be performed on the system.
