| dc.description.abstract | The use of Mobile and Wireless Information Technologies (MWIT) is outstandingly fast in every country of the world, from mobile phones, smartphones, laptops or tablets connected through wireless networks. The use of ERP (Enterprise Resource Planning) is completely spread among organizations, being a much studied topic since the late 90s. The use of MWIT with ERP systems is something that, even being used quite often in companies, has not been studied in academic field, and for that this paper attempts to identify how ERP systems have been used in an enterprise mobility perspective and what are the results of this use for the adopters. This paper is an exploratory research and is divided in three parts, the first one a survey with suppliers of ERP systems, the second a study on what features of ERP with mobility are used in three companies and to finish, a multiple study case with three companies users of ERP with mobility. The results show that only 34% of the surveyed ERP systems suppliers have mobile applications for their ERP. In addition, most applications (53%) is focused on sales, which reflects on the researched companies that only use sales support applications. Finally, it is shown that, in the studied companies, the use of ERP with mobility has increased productivity and efficiency, reduced costs, increased surveillance and control over employees and improved users life quality. It was also discovered that some research proposals could not be confirmed by the use of ERP with mobility, including data overload, improvement in relationship with customers and suppliers, improvement in organizational communication and profit increase. | en |
