Abstract:
This paper discusses the issues of the bidding process with emphasis on the design and manufacturing
uncertainties that can occur. The context of the paper is within manufacturing companies and in particular
within the Defence sector. The paper presents the bidding process of a large Manufacturing company and
details the main challenges and uncertainties that may occur. It also discusses the methods that are
currently used to tackle uncertainty. The results of an industry survey compare the practices of other
manufacturing companies and highlight the challenges at the bidding stage. The paper concludes that the
development of an appropriate framework is necessary in order to effectively manage uncertainty at the bid
stage.
