Authors
Pereira, J; Branco, F; Yong Oliveira, MA; Gonçalves, R;

Publication
Trends and Advances in Information Systems and Technologies - Volume 1 [WorldCIST'18, Naples, Italy, March 27-29, 2018].

Abstract
The top management view of organizations tends not to reach consensus on the prioritization of investments in Information Systems, particularly when they must prioritize their impact on overall performance and budget constraints. This paper presents the results of applying CRUDi Framework to a bank. This allows to obtain new indicators to support the decision and alignment of investment priorities in the processes that support the business strategy. The Framework introduces a new method and tools that allow us to gauge the relative importance of Information Systems to the organizations’ businesses. © 2018, Springer International Publishing AG, part of Springer Nature.

Peixoto, C; Martins, J; Gonçalves, R; Branco, F; Yong Oliveira, MA;

Publication

Abstract
The importance of e-commerce continues to grow in retail, providing companies with a critical tool to improve marketing and commercial strategies. In this context, understanding the distribution channels and the new business models becomes a fundamental issue for both researchers and business managers. This paper has two priority objectives. First is the accomplishment of a specific recent literature review survey on the theme of e-commerce platforms adoption that will support the next step. Second is to propose an adoption model that characterizes Discount and Outlet Platforms (DOP) adoption. The last contribution is distributed in the form of practical and theoretical implications, as well as future lines of action for possible investigations. © 2018, Springer International Publishing AG, part of Springer Nature.

Software adaptation to local cultures: The positioning of the Quatenus platform

Authors
Au Yong Oliveira, M; de Sousa, RJR; Goncalves, R;

Publication
2017 12TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)

Abstract
This article is a case study, based on Participant Observation, which focuses on a digital platform which manages assets. This platform is for sale in different countries, including Portugal and Mozambique. As national cultures and institutions differ from country to country and as this is all the more the case when different continents are at stake, we herein discuss the adaptation of products and services to the cultures and institutions of each environment, for the optimization of sales and product positioning. The data of the case study comes mainly from the experience of one of the authors, who lived in Mozambique for close to two years, linked to the selling there of the digital platform. A review of the existing literature was also performed. The strategic notion of positioning is central to the success of organizations and should differ from context to context, where necessary. Namely, different economic and education conditions lead to distinct behaviours, which have a repercussion on the posture to be adopted for the selling of products.

The Rise of the Unicorn: Shedding Light on the Creation of Technological Enterprises with Exponential Valuations

Authors

Publication
Trends and Advances in Information Systems and Technologies - Volume 1 [WorldCIST'18, Naples, Italy, March 27-29, 2018].

Abstract
The ambition to create start-ups with exponential valuations is the goal of many entrepreneurs. How may one create the so-called unicorns (start-ups with a valuation in excess of one billion US dollars)? Our study involved interviews and a focus group and a theoretical model was created. Business plans are surprisingly seen to be less important than is normally perceived, as is a higher education degree. The research also points to variables such as one’s DNA, experience, implementation capacity, intrinsic motivation, vision and timing, and the ability to seek feedback and learn from mistakes and not just from success. © 2018, Springer International Publishing AG, part of Springer Nature.

UNIVERSAL ACCESS IN THE INFORMATION SOCIETY

Abstract
Considering the importance associated with e-commerce website accessibility and usability, a study on one of the most relevant Portuguese e-commerce websites has been performed using both automatic and manual assessment procedures. In an initial stage, we evaluated the chosen website with a Web accessibility and usability automatic tool called SortSite; after that, we performed a manual evaluation to verify each previously detected error and present possible solutions to overcome those faults. In a third phase, three usability specialists have been used to perform a heuristic evaluation of the chosen website. Finally, user tests with blind people were carried out in order to fully assess the compliance with accessibility and usability guidelines and standards. The results showed that the platform had a good score regarding the automatic evaluation; however, when the heuristic and manual evaluations were performed, some accessibility and usability problems were discovered. Moreover, the user test results showed bad marks regarding efficiency, effectiveness, and satisfaction by the group of participants. As a conclusion, we highlight user interaction problems and propose seven recommendations focused on enhancing accessibility and usability of not only the evaluated e-commerce website, but also of other similar ones.

Technology usage as a way to increase safety and security in different geographies

Authors
Au Yong Oliveira, M; Moreira, F; Martins, J; Branco, F; Goncalves, R;

Publication
2018 13TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)

Abstract
This study follows an interpretivist approach and showcases five testimonials of technology usage in everyday life, in Rio de Janeiro, Brazil; the research also brings forward the perspectives of 31 other Brazilian citizens. The informants are Brazilian Master's level students who were on an exchange program to Portugal, at a major Portuguese university. Brazil, and in particular Rio de Janeiro, the focus of this study, are seen to have talented people and to be also open to technology - on the developing side as well as on the user side. Trust issues still exist - concerning e-commerce - and may indeed be pervasive in society. Brazil is currently undergoing a profound social and economic crisis, which it is trying to recover from. Indeed, the general lack of safety and security felt in Rio de Janeiro may even be a reason for the popularity of home and work deliveries - so that citizens will not have to travel - with travel constituting an additional risk which many may prefer to avoid. Thus, technology (a diverse set of apps) may be serving an additional purpose - that of ensuring security in daily life in Brazil.
