Purpose: The purpose of this paper is to contribute to OM Practice Contingency Research by describing the complexity of projects. Complexity is recognised as a key independent (con-tingent) variable that impacts on many subsequent decisions in the practice of managing pro-jects. Methodology:...

This document contains a bibliography of recent research relating to project risk management, bringing together relevant research scattered across a range of publications. It considers how success or failure can be defined for a project (more than simple time/cost/technical target achievement)....

Learning lessons from projects is important, but the practice of project post-mortems does not occur frequently in practice. Recent work suggests that, one reason might be the difficulty in identifying the "hard", non-intuitive lessons from projects, such as those resulting from feedback and...

There has been much prescriptive work in project management, exemplified in various "Bodies of Knowledge". However, experience shows some projects overspending considerably. Recently, systemic modeling research into the behavior of large projects explains project oversponds by "systemic" effects...

This paper reports on a model building process developed to enable multiple audiences, particularly non-experts, to appreciate the validity of the models being built and their outcomes. The process is a four stage reversible cascade. This cascade provides a structured, auditable/transparent,...

This paper describes a method for apportioning contingency in a probabilistic network. It distinguishes between two requirements for contingency: for high variance crucial activities, and for high float noncritical activities. This enables a logical two-step apportionment, the first based upon...

In a production-inventory system, the manufacturer produces the items at a rate, e.g. R, dispatches the order quantities to the customers in specific intervals and stores the excess inventory for subsequent deliveries. Therefore each inventory cycle of the manufacturer can be divided into two...
