Abstract. Event-driven architecture (EDA) is an architectural approach for enabling communication between distributed enterprise information systems. EDA enables organisations to be adaptable, flexible and robust in the management of business processes and ultimately achieving agility. This paper reviews definitions, concepts and adoption criteria for an EDA and a case study investigates the adoption of the EDA in a micro lending organisation exploring the technological, organisational and environmental adoption factors. Keywords: Event-driven architecture
Distributed EIS SOA IS adoption
1 Introduction Organisations need to be agile in order to accommodate changes to environmental conditions and customer demands [1]. To achieve agility, organisations are obligated to react to opportunities and pressures in order to continuously monitor and optimise business processes. In order to do this, organisations are dependent on the underlying information systems to make decisions pertaining to these business processes [2]. In the development of enterprise-wide information systems, communication, both internal and external to the organisation, is required. This communication is not only between information systems but within the components of the information system [3]. To facilitate this communication, information systems are reliant on events that are responsible for the triggering of business processes. Event-driven architecture (EDA) is an emerging information systems paradigm and architectural approach that facilitates the communication between disparate information systems [4]. The research problem is that little is known about the drivers and issues relating to the implementation of EDA in a real-world context. The goal of this research is to provide a deeper insight into the adoption of an EDA, and particularly relating to the Technological, Organisational and Environmental (TOE) factors which can drive the organisational adoption of EDA. This is achieved by exploring the adoption of an EDA within the context of a Micro Lending Organisation (MLO) in the form of a case study.

2 Literature Review The event-driven paradigm represents a real time occurrence of an event within a domain. This event could be any internal or external activity performed and can initiate a single or multiple actions. Business events are procedures that affect the organisation’s business processes. These business events are a change in state, related to the business processes. This state could be a customer interacting with a product, a change in the operational environment or a reaction to competitors [5]. EDA is a methodology that allows for the production, detection, consumption and reaction to events. These events are propagated in real time to all event generators and
