IT outsourcing configuration: Research into defining and designing outsourcing arrangements

Sara Cullen; Peter B. Seddon; Leslie P. Willcocks

Abstract In this paper, we introduce the concept of information technology outsourcing (ITO) ‘configuration’, defined as: a high-level description of the set of choices the organization makes in crafting its IT outsourcing portfolio. From research into 49 ITO arrangements studied over time, we identify seven attributes—Scope Grouping, Supplier Grouping, Financial Scale, Duration, Pricing, Resource Ownership, and Commercial Relationship—as key descriptors of an organizations ITO configuration. Seven further cases tested the relevance of the attributes. The contribution of this paper is its articulation of the concept of configuration as a taxonomy of ITO structural characteristics, the key attributes, and demonstration that configuration is an important concept for understanding, comparing, and managing ITO arrangements. In particular, the paper details the rationales for 31 different options in outsourcing, the risks and management issues emerging for each, and how these play out in different combinations in selected, illustrative case studies.

Does Domberger's theory of ‘The Contracting Organization’ explain why organizations outsource IT and the levels of satisfaction achieved?

Peter B. Seddon; Sara Cullen; Leslie P. Willcocks

This paper contributes an interpretation of Dombergers theory of The Contracting Organization for use in an IT outsourcing context, then presents a preliminary test of the validity of that theory using data from an Australian survey of 235 senior IT managers. Our conclusion is that Dombergers theory appears to be a useful lens for understanding IT outsourcing, and that further research using purpose-collected data is therefore warranted. Phrased differently, Dombergers four types of benefit of contracting – namely Specialization, Market Discipline, Flexibility, and Cost Savings – appear to be a good way of summarizing senior IT managers’ explanations of why their organizations chose to outsource IT. The paper also conducts a preliminary test of the extent to which these four factors explain the purchasing organizations satisfaction with IT outsourcing.

Managing the sourcing process: A life cycle perspective

Sara Cullen; Peter B. Seddon; Leslie P. Willcocks

Outsourcing, whether of IT or business processes, onshore or offshore, continues to raise expectations and pose challenges for private and public sector organizations alike. Time and again, we have found even experienced organizations running into massive problems, suffering from slow organizational learning, and working in a reactive rather than an anticipatory mode.1 The results are troubling. Here are some recent examples: In 2000, UK retailer Sainsbury signed a seven-year US

A Framework for Relationships in Outsourcing: Contract Management Archetypes

Sara Cullen; Graeme G. Shanks; Michael Davern; Leslie P. Willcocks

There has now been over a decade of information technology outsourcing (ITO) research producing a considerable volume of thoughts, theories and propositions regarding outsourcing. A search on Amazon.com will typically yield over 200 titles and Hui and Beath (2001) uncovered 143 papers and books on IT sourcing in major academic journals and the like.
