After years of experience with building systems, the information systems (IS) community is still challenged by systems delivery, that is, planning the implementation project, determining system features and requirements, sourcing and deploying the software, and managing its evolution.
Alibaba is Laboratory Information System (LIS) designed to help clinics/hospitals easily and effectively manage all laboratory operations. It also provides other added values such as: remote monitoring lab, return test result to patient remotely via LAN, internet, web, SMS …
Information Systems are the software and hardware systems that support data‐
intensive applications. One of the most critical stages of an Information System
development cycle is the System Design stage. During this stage the architecture,
components, modules, interfaces and system data are defined and modeled in order to
fulfill the respective requirements that the developed Information System should
meet. For accomplishing this task a number...
It is now almost 40 years since Roger Tomlinson coined the term geographic
information system (GIS), and led the development of the world’s
first, the Canada Geographic Information System (CGIS), in the mid-1960s
(for a history of GIS see Foresman 1998). Today’s technology would be
almost unrecognizable to the pioneers of the 1960s, not only because of the
almost unbelievable advances in information technology (IT) that have
occurred since then, but also because of dramatic changes in the functionality,
appearance, use, and societal context of GIS.
Nowadays, Information and Communication Systems Technologies are rapidly
expanding in order to fulfill the increased needs of our demanding modern
Information Society. More and more fundings are invested every year for the
development of new, innovative and technologically advanced Information Systems
that will be efficient enough to satisfy users’ requirements and be adaptive enough so
as to cooperate with the cutting‐edge aspects of IT and mobile technologies.
The study focuses on the use of information systems in the Heavy Engineering industry in South Africa and the decision to make, buy or rent information systems. Special focus was placed on the factors that influence the decision to make, buy or rent information systems. It is undeniable that changes in the competitive environment, such as technological advances and globalisation, are driving organisations toward new ways of operating. In striving to become flexible, lean, and more competitive, organisations have been increasingly swift to externalise support service functions.
