In the contemporary business climate of hyper-competition, volatility and increasingly pervasive technologies, the demand for organisational agility and responsiveness accentuate the degree to which success is linked to managerial decision making: more decisions need to be made, at greater speed, with superior precision in order to achieve effective outcomes. This unit examines the different types of decisions that managers make, embedding these within a variety of business processes and contexts. We examine the role of technologies in providing and analysing this information, whether it is from transactional e-commerce applications, enterprise collaboration systems or customers via social media.
