IMPORTANCE OF SOFTWARE QUALITY MODELS IN SOFTWARE ENGINEERING

Software quality models are a well-accepted means to support quality management of software systems. Over the last 30 years, a multitude of quality models have been proposed and applied with varying degrees of success. Despite successes and standardisation efforts, quality models are still being criticised, as their application in practice exhibits various problems. To some extent, this criticism is caused by an unclear definition of what quality models are and which purposes they serve. Beyond this, there is a lack of explicitly stated requirements for quality models with respect to their intended mode of application. To remedy this, this paper describes purposes and usage scenarios of quality models and, based on the literature and experiences from the authors, collects critique of existing models. From this, general requirements for quality models are derived. The requirements can be used to support the evaluation of existing quality models for a given context or to guide further quality model development.

In last decade, researchers have often tried to improve the usability, portability, integrity and other aspects of software in order for it to be more users friendly and gain user trust. Several approaches and techniques have been proposed to reduce the negative effects of software size and complexity. Moreover, several software quality models were proposed to evaluate general and specific type of software products. These models were proposed to evaluate general or specific scopes of software products. The proposed models were developed based on comparisons between the well-known models, in order to customize the closed model to the intended scope. These comparisons are leak of criteria that is conducted based on different perspectives and understanding. Therefore, a formal method of comparison between software quality models is proposed. The proposed method is applied on a comprehensive comparison between well-known software quality models. The result of the proposed method shows the strength and weaknesses of those models.

To stay ahead in competition, software organizations have to deliver required functionality consistently guaranteed with high quality. The quality expectations of customers at purchase time from the software is the major reason of emergent attention of software organizations to implement quality management in software development. Nowadays, use of Component Based Software Development (CBSD) approach is considered success factor for business because of its underlying benefits like reusability, on-time delivery, high quality, and less cost. But success of CBSD depends upon the quality of components used. Many quality models have been proposed to provide high quality products, some of these are for general usage and others are for specific applications or domains. These specific purpose models are improved or modified forms of basic quality models especially ISO 9126. This paper presents key challenges or deterrents to the development of standard, complete and pervasive software qualit...

This paper presents acomprehensive overview ofQuality, definition of quality by different person and alsothis paper present overview on Software Quality Models, McCall's Quality Model, Boehm's Quality Model, Dromey's Quality Model, FURPS Quality Model, ISO 9126 Quality Modeland a comparison among these models are presented.

With the objective of presenting qualitative software system most of the software producers have endeavoured and infact this is their main purpose. Software quality is having multi-dimensional content which may be distinguished and measured easily. To be specific, with the idea of determining the multidimensional content in a more exact pattern various qualitative models have been presented by virtue of which different aspects of this matter have been attempted to be investigated properly. Practically as because there are existences of different models which have used different expressions the comprehension of this basic content have become to some extent hard or difficult. Attempts have been made in this particular paper to introduce some models that have been mentioned and more clearly analysis the qualitative characteristics and side-by-side determine the software quality along with the analytical comparison of these models. This paper may serve the purpose of a reference for investigating software quality and its related models.

In the given paper I present the information regarding quality metrics. Software systems are getting larger and more complex. It takes therefore more time and money to maintain these systems. The maintenance effort is strongly related to the quality of the implementation during the development phase. Providing qualitative numbers to developers about their previous implementations could help increase the quality of their next implementation. Different quality factors can be imposing with relation to cost, schedule and rework. It's very important to make quality assurance plans. For that you have to cover many milestones which can be represented in time sheets. The main characteristics of the quality models have covered in this paper.

Actually, software products are increasing inside a fast way and they are used in nearly all activities of people life. As a consequence measuring and evaluating the standard of a software product is now crucial task for most companies. Several models are anticipated to help different kinds of users having quality issues. This paper analyses our ability to measure software excellent. The analysis is dependent on the representational hypothesis of measurement. We dissect three assumptions on application quality measurement and suggest a higher measurement focus with establishing experimental relational programs (models of what we should measure) in application quality related perform. Actually, software products are increasing in a fast way and are used in almost all activities of human life. Keywords— Software Quality, Software Quality Model, Quality

INTRODUCTION: The emerging industrialization of software promotes the continuous development of new evaluation models that adapt to the product's characteristics and the organizations' needs. OBJECTIVES: This article aims to identify the software quality models proposed between 2016 and 2020. METHODS: We conducted an exploratory systematic review in the SciELO, IEEE Xplore, and Scopus databases, resulting in 14 research papers proposing new models for assessing software quality. RESULTS: 79% of the research papers were extracted from IEEE Xplore, and 50% of them were authored by individuals affiliated with European institutions. We presented various software quality models focused on assessing both product quality and usability for specific purposes. Additionally, we reported that the proposed models are based on common software quality metrics standards such as CMMI, ISO/IEC 9126, and others. CONCLUSION: The review serves to update the state of the art regarding the softwar...

Actually, software products are increasing in a fast way and are used in almost all activities of human life. Consequently measuring and evaluating the quality of a software product has become a critical task for many companies. Several models have been proposed to help diverse types of users with quality issues. The development of techniques for building software has influenced the creation of models to assess the quality. Since 2000 the construction of software started to depend on generated or manufactured components and gave rise to new challenges for assessing quality. These components introduce new concepts such as configurability, reusability, availability, better quality and lower cost. Consequently the models are classified in basic models which were developed until 2000, and those based on components called tailored quality models. The purpose of this article is to describe the main models with their strengths and point out some deficiencies. In this work, we conclude that in the present age, aspects of communications play an important factor in the quality of software
