CMMS software quality function deployment based on maintenance objectives: a framework for software selection process

This paper aims to propose a framework for identifying and prioritising software features of CMMS success factors. In order to achieve this goal, we tried to identify customers and users' requirements of this software using a two-stage QFD approach and suggest features and specifications for new products and services afterwards. The results of this study represent that the most important CMMS software features that can greatly influence the success of CMMS implementation are: possibility to use in multiple locations, simplicity and being user friendly (the use of shareholders from the software menu), facilities for computing external maintenance costs and automated reorder. In this research, a systematic structure is proposed to improve the process of choosing the right CMMS software and its development. The CMMS software requirements are tailored to the company's maintenance goals which contribute positively to the value of organisational processes.

A decision model for setting target levels in software quality function deployment to respond to rapidly changing customer needs

Responding to the need for enhanced software quality, software manufacturers have recently applied quality improvement techniques to software development process. Software quality function deployment, as a technique for better quality designs that match customer expectations, has been used in software development to maximize customer satisfaction. This article proposes a fuzzy regression-based decision framework that considers future requirements for setting target levels of technical attributes in software quality function deployment. Ordered weighted averaging operators are employed to implement quantifier-guided aggregations that enable to calculate the integrated importance degree for each customer need by combining the current and future voice of customers. Then, a fuzzy optimization model, which considers the integrated importance degrees of customer needs and uses the functional relationships obtained by fuzzy regression, is developed to determine target levels of technical attributes of the new or improved software products that meet customer needs at the time when the product reaches the market. The fuzzy optimization model includes both the center values and the spread values of the parameter estimates and thus circumvents loss of information in determining target levels of technical attributes. A search engine quality improvement problem is presented to illustrate the proposed decision framework.

DEVELOPMENT AND APPLICATION OF SQFD MODEL FOR AN INNOVATIVE EMBEDDED SOFTWARE PRODUCT - A CASE STUDY

This paper discusses the development and application of Software Quality Function Deployment (SQFD) Model for a new embedded software product. A detailed Literature study has been carried out on the applications of QFD model for software development. An integrated SQFD model with House of Quality (HOQ), Subsystem/Module Deployment Matrix and Technology Deployment Matrix is developed. The proposed SQFD model has been implemented for developing a new embedded software product. From the HOQ matrix reveals that the ‘image capture button’ and ‘imaging’ has been identified as the most important technical requirement for this product. The “Procedure Recording” Subsystem has been identified as the most critical subsystem that affects the design. The most suitable technology that meets the design is the ‘Prism+, pSOS’. Accordingly, recommendations are made to the company. The study demonstrates that the SQFD technique is suitably applied using SQFD Model in an embedded software product, and it is appropriate for the design and development of new software products.

Reliability improvement in component-based software development environment

Software quality is becoming increasingly important since software is now used in many demanding applications and also in safety critical systems. Reliable functioning of software systems is paramount concern to millions of users who depend on it every day. Unfortunately most of the systems still fall short of user expectation of reliability. Component-based software development is a new approach based on the idea that software systems can be developed by selecting appropriate off-the-shelf components and then assembling them with well-defined software architecture. In this paper, it is proposed to apply the software quality function deployment technique in a systematic manner to manage the software development process to improve the quality of the component based software by improving its reliability. This approach is applied in ERP software and the results show that software quality function deployment is best suitable for improving the quality of component based software development.

REQUIREMENTS AND WISHED FEATURES FOR SOFTWARE TESTING TOOLS: A STUDY BASED ON THE USE OF SQFD

This paper presents a set of requirements related to software testing tools. These requirements were elicited during several meetings with software development professionals. We adopted the software quality function deployment (SQFD) in order to prioritize the identified requirements and technical issues, generating relevant information regarding the testing tools. This information can be used to compare and select testing tools. It can also be used by testing tool developers to direct their development effort towards aspects considered important by the users of this kind of tools, the testers.

A fuzzy regression and optimization approach for setting target levels in software quality function deployment

With the rapid development of the software industry, improving the quality of software development has gained increasing importance. Software manufacturers have recently applied quality improvement techniques to software development to respond to the needs for software quality. Software quality function deployment (SQFD), as a technique for improving the quality of the software development process to create products responsive to customer expectations, is used to maximize customer satisfaction. This paper presents a fuzzy regression and optimization approach to determine target levels in SQFD. The inherent fuzziness of relationships in SQFD modeling justifies the use of fuzzy regression. Fuzzy regression is used to identify the functional relationships between customer requirements and technical attributes, and among technical attributes. Then, a mathematical programming model is developed to determine target levels of technical attributes using the functional relationships obtained by fuzzy regression. A search engine quality improvement problem is presented to illustrate the application of the proposed approach.

A Quantity Model for Controlling and Measuring Software Quality Based on the Expert Decision-Making Algorithm

Researchers have been active in the field of software engineering measurement over more than 30 years. The software quality product is becoming increasingly important in the computerized society. Target setting in software quality function and usability deployment are essential since they are directly related to development of high quality products with high customer satisfaction. Software quality can be measured as the degree to which a particular software program complies with consumer demand regarding function and characteristics. Target setting is usually subjective in practice, which is unscientific. Therefore, this study proposes a quantity model for controlling and measuring software quality via the expert decision-making algorithm-based method for constructing an evaluation method can provide software in relation to users and purchasers, thus enabling administrators or decision makers to identify the most appropriate software quality. Importantly, the proposed model can provide s users and purchasers a reference material, making it highly applicable for academic and government purposes.

The leading edge in QFD for software and electronic business

In this article an overview of the state‐of‐the‐art of Quality Function Deployment (QFD) in software development or also called software QFD is given. The differences between classic QFD in manufacturing industries and software QFD are described. Following that certain software‐specific QFD models (Zultner, Shindo, Ohmori, Herzwurm and Schockert), which can be considered the most appreciated ones in theory as well as in practice, are introduced. Experiences in practice with these software QFD models are presented as well. Finally, through explaining the main principles of a special QFD variant for e‐commerce, called continuous QFD (CQFD), the article will show that QFD is suitable for planning electronic business applications as well.

A Quality-Enhancing Software Function Deployment Model

Software quality has become a topic of increasing importance during the past decade. the quality of software is primarily determined by the quality of the software development process. Even small improvements in the software development process can result in a significant improvement in software quality. the use of software metrics technologies to assess design quality is a key issue in the management of information systems. Software Quality Function Deployment (SQFD) is a useful requirement-gathering tool, especially in communication with users and meeting user requirements. However, software quality cannot be reviewed in isolation. Without an assessment of the goals of a project, the efficiency of software function derived from customer requirements is meaningless. This article proposes an enhanced software quality function deployment process of integrating Goal-Question-Metrics and Software Quality Function Deployment. A software development process with this model will enhance the quality of the software. A case study is also presented to illustrate the enhanced software quality function deployment process. the main contribution of this article is to help software developers produce higher-quality software that not only meets customer requirements, but also achieves the goals of the project.

Software quality function deployment

Any product development involves projecting its potential success in achieving its functional and commercial goals. Better quality designs that match customer needs and preferences and integrate other lifecycle issues early in the software development process are more likely to be competitive. Thus, there is significant concern in industry about quality product design, which is addressed by quality function deployment (QFD). QFD uses matrices to organize and relate pieces of data to each other. These matrices are often combined to form a basic tool of QFD, called a House of Quality (HoQ). QFD was developed in the Kobe shipyards as a way to expand and implement the view of quality as taught by W. Edwards Deming and others. It has been widely applied in many industries worldwide, such as automobile, electronics, food processing, computer hardware and software ever since. Software quality function deployment (SQFD) focuses on improving the quality of both the software development process and the product. The improvement in software quality leads to fewer changes in requirements specification, design, and code, a reduction in the number of defects and less rework, and therefore, higher productivity.

Application of QFD to the software development process

Explores the issue of software development process improvement. Total quality management (TQM) tools have been studied as possible means to improve the quality of the software that is becoming an important part of organizational processes. The TQM philosophy that has been so successfully applied in manufacturing holds that quality must be built into the production process and not inspected into the product. Given the complexity of modern software applications, the ability to move away from using testing and inspection as quality control methods is very attractive. Examines the current literature on software development process improvement. Particular attention is paid to how customer requirements are gathered and translated into system requirements. Finds that current methods for requirements definition do not provide a formal means to deploy the “voice of the customer” into system specifications. Further, finds after a review, that current software quality function deployment (QFD) methods suffer from a number of shortcomings. Proposes a four‐stage model for performing software‐oriented QFD to address these significant problems.

Software Quality Function Deployment

is essentially defined as 'fitness for purpose'. The above statement is found in that form, or in a similar paraphrase, in most writings on quality assurance procedures. It begs the questions that we all know what 'fitness' means and that there is a single 'purpose' being targeted. is binary. A product either has it or it does not. There is no such thing as degrees of Another quotation concerning quality, including software quality. We feel that we should be able to endorse the sentiment yet we all know that we must reconcile it with the notion that we only get what we pay for and that, to some extent, quality lies in the eye of the beholder. The practice of Quality Function Deployment (QFD) is concerned with the identification of the various interests of the stakeholders in the development of a product and of the criteria which they would use to define quality. Once these criteria have been agreed upon by the client and the developer, quality shifts from the subjective to the binary. It is the intention of this paper to : • elaborate on the system attributes comprising software quality, • examine the (often mutually conflicting) requirements of the stakeholders in a software product, and • suggest the means whereby the conflict may be resolved and the criteria by which software quality is determined may be measured.
