<jats:p><jats:bold>Abstract. </jats:bold> This paper discusses the management problems associated with building and implementing large systems. The example described is XSEL, a configuring expert system designed by the Digital Equipment Corporation for worldwide application.</jats:p><jats:p>Digital, like many other larger computer manufacturers, had experienced problems in achieving a high level of configuring accuracy when assembling its computer. These problems showed up in the manufacturing plants but originated in the sales offices. They caused difficulties with customers and increased manufacturing and selling costs. The company decided that an expert system could solve the problem.</jats:p><jats:p>The processes associated with the design of this successful system created as many human as technical challenges. The paper describes these, discusses how and why they originated, and evaluates Digital's strategies for solving them. It makes some general recommendations for the successful management of major change.</jats:p>
