Mobile flight and hotel booking application: A heuristic and UX test

The purpose of this study is to present the usability evaluation of the mobile flight and hotel booking application. Currently, mobile applications have offered the easiness to users in order to book flight and hotel. Unfortunately, there is a lack of study on usability that focuses on mobile booking application, while many people start to do all the transactions on their mobile phone.This study will conduct two combined usability evaluation methods which are heuristic and UX test.Ticket.com will be evaluated as it is a critical application that can represent the study of this usability testing.Those selected usability evaluation methods are to evaluate mobile application based on usability experts and end users to get feedbacks and propose solutions and recommendations to improve the application. Observation and questionnaire will be used to measure the metric of effectiveness, efficiency and satisfaction.The heuristic is conducted by three usability experts. Whereas, the UX test participants are ten persons that will be randomly selected either from novice users or the one who experience purchasing flight ticket and hotel reservation on mobile.The result of the study revealed that the application is not easy-to-use and inconsistent as it has been proven by usability score of this application is 66% or below average. It is expected that this study can be adopted by developers and usability practitioners to deliver a user-friendly mobile application that leads to high customer satisfaction

Usability evaluation of a web-based health awareness portal on smartphone devices using ISO 9241-11 model

Much effort has been devoted to evaluating the usability of web-based system.With the increase in the mobile-based applications coupled with the limitations and challenges of mobile devices, it becomes mandatory to evaluate the web-based systems in the context of smartphone usability.In addition, a number of international standards/models on usability are available, but seldom used for practical usability evaluation. In this study, the popular ISO 9241-11 standard was used to evaluate a web-based health awareness portal within the smartphone mobile context.The results reveal some pointers to usability issues as well as confirmation that the web-based awareness portal is relatively usable on smartphone devices within the components defined in the models

An application of the ISO/IEC 25010 standard in the quality-in-use assessment of an online health awareness system

Research studies show that there is an upsurge in the number of users surfing the Internet for online health related information.This increase in information seeking behavior on the Web gives rise to the need to ensure that Web based portals meet basic quality in use standards.The ISO/IEC 25010 standard was developed as a model for evaluating such quality in user expectations.In this paper, this standard was used to assess the quality in use of e-Ebola Awareness System, an online health awareness portal. The results provide some insights into the quality into the use of the online portal and also pointing to some issues that impact negatively on the quality in use of the portal, demanding attention and improvement

The effect of responsive web design on the user experience with laptop and smartphone devices

The introduction of smartphones with their accompanying capacity to access the Internet, changed the way the Internet is used.Many people now use mobile devices to browse the Web. However, the varying screen sizes of these devices portend some impact on their users’ experience, as the Web content on the devices vary in size and the navigation of pages are also different in the various devices.The advent of the responsive web design (RWD) philosophy, revolutionized the way Web pages are designed and the way they appear to the users in the various devices.RWD makes Web pages to adjust to the size of any devices’ screen irrespective of the device type.In this study, the effect of responsive web design of the user experience with a laptop and smartphone devices while using the e-Ebola Awareness System, (a Web based health awareness portal for Ebola virus disease), was measured and evaluated. The results revealed that users had a better user experience with Smartphones than with laptops while using the system, however, for most of the metrics collected, users’ experiences with the two device types were not significantly different at 95% level of confidence, implying that for those metrics, the responsive web design had a similar effect on the users’ experiences and attitudes

Ontology of zakat management system

Zakat Management System is a system that manages all the processes that are involved in zakat activities.At present, there exist no standard which can be utilized to develop Zakat Management System. In order to support the development of Zakat Management System, this paper provides the ontology of Zakat Management System aimed specifically to share the knowledge of zakat. Each person who are involved in the development of this system will hopefully share a common understanding of Zakat Management System. This in turn will make the process of development faster

Faktor Kejayaan Kritikal Pengurusan Projek : Suatu Kes Kajian Kes Projek KLIA

Project management is one of the most important management science or operational research techniques, which can be applied across disciplines. Engineering, construction, information system development, or non-commercial projects usually involve costs, management of resources in particular people, compliance to user and client specification, and meeting deadlines. It is the control of complex activities and it can affect the entire culture of an organization. The construction and completion of the Kuala Lumpur International Airport within the specified date, user specification and budget is an example of how a huge project is managed successfully from inception to its operations. KLIA was designed, planned and built to meet the demand from the air-travelers who expected high standards as the existing Sultan Abdul Aziz Shah International Airport (SAAS) was thought to have reached its limits. Several factors that contribute to success of project management are experience personal selected to manage the given project, better accommodation to ensure personnel satisfaction, effective communication and the usage of the best tools and techniques

GOSSEC: Goal Oriented Software Sustainability Evaluation Criteria

The concepts of sustainability is now aware among the software engineering researchers.  It has direct and indirect impacts on three dimensions which are environment, economic and social that results from the development and implementation of the software. Although there are studies on software sustainability evaluation that defines the software sustainability criteria unfortunately, most of the studies are focusing on single criterion rather than come out with holistic criteria of software sustainability. Additionally, the studies also focused on what need to be measured instead of how to perform the evaluation systematically. This limitation was occurred due to lack of defining the measurement goal of each criteria of software sustainability dimensions. Therefore, this study aimed to develop a Goal Oriented Software Sustainability Evaluation Criteria and organize the sustainability criteria using Quality Function Deployment. On top of that, the Goal Oriented Software Sustainability Evaluation Criteria has been constructed using Goal Oriented Measurement approach by adapting the Goal Question Metric method to assist in defining the goal that clearly defined the purposes, perspectives, and point of views of measurement of software sustainability. Hence, the Goal Oriented Software Sustainability Evaluation Criteria provides nine (9) goals and thirty four (34) sub goals for measuring the software sustainability criteria and sub criteria. The findings from the study present a set of criteria and measurement goals which can be used for evaluating software sustainability. The criteria were organized into three dimensions which are environment, economic and social.   &nbsp
