A Threefold User-Based Software Evaluation Framework

While pressured to release new software to market, software development organization often find themselves choosing between quality and timeliness. From a business perspective, success is determined to a significant extent by the perceptions of quality exhibited by consumers with respect to the software product being offered. In this context, we propose taxonomy of software users and design a user-centered software evaluation framework to support software quality assessment processes. An online survey is conducted for exploring software users’ perceptions of quality and the results are used to define three categories of software users. The findings of this study shed new light on the way software development organizations should perceive the relationship with their consumers and, consequently, on the way they should manage development projects. The contributions to both research and practice stem from the proposing of a new and more detailed approach to defining and measuring software system quality and its associated assessment processes

Software certification modeling: from technical to user centric approach

One of the most essential issues in software products is to maintain it relevancy to the dynamics of the user's needs. Many researches and studies have been carried out in quality aspect of software products to overcome these problems. Several software quality assessment models and metrics have been introduced with strengths and limitations. The current quality models such as McCall, Boehm, ISO9126, Sistemic and PQF model are used as the benchmark for product assessment. In order to enhance the assurance and buoyancy of the software products, certification process and models have been introduced and developed. Previous fundamental and basic software certification models such as SCM-Prod and SPAC were developed to solve the uncertainties in software quality in two views which are the end product and the development process. However, the models are based on specific requirements and have certain limitations. SCM-Prod model focuses on the certification and quality requirements of software products in general. While SPAC model focuses on software certification based on development process approach. Our previous experiences in conducting certification exercises and case studies collaborating with several agencies in Malaysia, the requirements for user based software certification approach is needed and demanded. The emergence of social network applications and other varieties of software in the market has led to the domination of users over the software. As software become more accessible to the public through internet applications, users are becoming more critical in the quality of the services provided by the software. Users should be able to assess and certify their own products within their own environment at anytime and anywhere. The quality attributes for software assessment should be based on user's perspective and view. This new paradigm should the alternative focus in software product quality assessment and certification. This paper presents the evolution of software certification and assessment from technical view to user centric approach. It discusses the concept of user centric approach in software assessment and certification which also focuses on the design and development of the model (ucSoftC), the components and attributes embedded in this model. The development is believed to be beneficial and valuable to overcome the constraints and improve the application of software certification model in future

Group Decision Making for a Fuzzy Software Quality Assessment Model to Evaluate User Satisfaction

Information techniques have brought us tremendous benefit, whereas people are increasingly depended on lots of information systems. Therefore, how to establish an assessment model to choose a better software quality suitable for end-users is an important issue. This study is to present an algorithm of the group decision makers with crisp or fuzzy weights to tackle the integrated software quality for evaluating user satisfaction using fuzzy set theory, where the grades of quality and the grade of importance of quality items are assessed by linguistic values represented by triangular fuzzy numbers. The proposed algorithm is more flexible and useful than the ones that have presented before, since the weights against decision makers are considered

The Value of Crowdsourcing for Complex Problems: Comparative Evidence from Software Developed By the Crowd And Professionals

Crowdsourcing is a problem solving model. In the context of complex problems, conventional theory suggests that solving complex problems is a province of professionals, that is, people with sufficient knowledge about the domain. Prior literature has indicated that the crowd, in addition to professionals, is also a great source for solving problems such as product innovation and idea generation. However, this assumption has yet to be tested. Adopting a quasi-experimental approach, this study uses a two-phase process to investigate this question. In the first phase we compare the development of a software by the crowd and professionals. In the second phase we evaluate the software developed by the crowdsourcing business model and professionals in terms of key perceived quality dimensions assessed by users of the systems. Quality is measured in terms of pragmatic quality, hedonic quality stimulation, and hedonic quality identification. Our study results suggest that there is a statistically significant difference between the software developed by a crowdsourcing business model and professionals in terms of hedonic quality stimulation and hedonic quality identification but there is no difference in terms of pragmatic quality. This research offers a first assessment of whether a crowdsourcing business model can be used to develop software with better user experience than professionallydeveloped software

A complex physiology-based empirical usability evaluation method in practice

This paper outlines the INTERFACE usability evaluation methodology developed by researchers of our department. It is based on the simultaneous assessment of Heart Period Variability (HPV), Skin Conductance (SC), and other data. One of the highlights of this methodology is its capability to identify quality attributes of software elements with a time-resolution of only a few seconds: in particular cases it can assess 2- or 3-second events. The Department of Ergonomics and Psychology at the Budapest University of Technology and Economics carried out applied research projects assessing very various software. After these, we can show different types of typical software problems identified by our method. The method of analysis allows us not only to decide what types of problems are significant to the users; however, on the other hand, the method allows us to decide, to what extent the found problems and their assessed severity concern all the users in general, or how these things depend on the type and characteris tics of the users

Developing a global risk engine

Risk analysis is a critical link in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment software. However, there is a significant disparity between the high quality scientific data developed by researchers and the availability of versatile, open and user-friendly risk analysis tools to meet the demands of end-users. In the past few years several open-source software have been developed that play an important role in the seismic research, such as OpenSHA and OpenSEES. There is however still a gap when it comes to open-source risk assessment tools and software. In order to fill this gap, the Global Earthquake Model (GEM) has been created. GEM is an internationally sanctioned program initiated by the OECD that aims to build independent, open standards to calculate and communicate earthquake risk around the world. This initiative started with a one-year pilot project named GEM1, during which an evaluation of a number of existing risk software was carried out. After a critical review of the results it was concluded that none of the software were adequate for GEM requirements and therefore, a new object-oriented tool was to be developed. This paper presents a summary of some of the most well known applications used in risk analysis, highlighting the main aspects that were considered for the development of this risk platform. The research that was carried out in order to gather all of the necessary information to build this tool was distributed in four different areas: information technology approach, seismic hazard resources, vulnerability assessment methodologies and sources of exposure data. The main aspects and findings for each of these areas will be presented as well as how these features were incorporated in the up-to-date risk engine. Currently, the risk engine is capable of predicting human or economical losses worldwide considering both deterministic and probabilistic-based events, using vulnerability curves. A first version of GEM will become available at the end of 2013. Until then the risk engine will continue to be developed by a growing community of developers, using a dedicated open-source platform
