Leadership: should it have a future?


This seminar asks: should leadership have a future? It builds on a recent debate in the journal Leadership in which Mark Learmonth and Kevin Morrell questioned the status of leadership as an academic subject and organizational practice. Dennis Tourish, co-editor of Leadership, and Jackie Ford, both major critical leadership scholars, disagree. They think there is a future for leadership, albeit a different one from the dominant models that originate largely in the US. This seminar, hosted jointly by the Future of Work and the Strategy and Leadership research centres at the University of Bath School of Management, will delve into this argument.

Chair: Professor Nancy Harding, University of Bath

Location: Chancellors' Building 3.15, University of Bath

A general framework to compare announcement accuracy: static vs LES-based announcement


Service providers often share delay information, in the form of delay announcements, with their customers. In practice, simple delay announcements, such as average waiting times or a weighted average of previously delayed customers, are often used. Our goal in this talk is to gain insight into when such announcements perform well. To do so, the accuracies are compared of two announcements: (i) a static announcement which does not exploit real-time information about the state of the system, and (ii) a dynamic announcement, specifically the last-to-enter-service (LES) announcement, which equals the delay of the last customer to have entered service at the time of the announcement. So far, the literature on delay announcements has focused, for the most part, on studying the accuracy of various types of announcements in specific queueing models. As such, the validity of various announcements remains intimately tied to the appropriateness of the technical conditions under which these models were studied. In other words, in order to decide whether a type of announcement is appropriate for her system, a manager would need to assess whether a certain queueing model is a good fit for her data. Because this is often difficult to do, we propose a new approach in this talk. In particular, a proposed a novel correlation-based approach which is theoretically appealing because it allows for a comparison of the performances of announcements across different queueing models, including multi-class models with a priority service discipline. It is also practically useful because estimating correlations is much easier than fitting an entire queueing model. Using a combination of queuing-theoretic analysis, real-life data analysis, and simulation, we analyze the performance of static and dynamic announcements, and derive an appropriate weighted average of the two which we demonstrate has a superior performance using both simulation and actual call centre data.
