Powell emphasized that the low initial investment was possible because most of the components and subsystems were purchased from contractors and vendors. Even internal centers of excellence such as SE Labs and Pantak assembled their subsystems from purchased components. Overall, outside vendors accounted for 75% to 80% of the scanner's manufacturing cost. Although Powell felt his arrangement greatly reduced EMI's risk, the £6 million investment was a substantial one for the company, representing about half the funds available for capital investment over the coming year. (See Exhibit 2 for a balance sheet and Exhibit 3 for a projected funds flow.) The technology strategy was to keep CRL as the company's center of excellence for design and software expertise, and to use the substantial profits Powell was projecting from even the earliest sales to maintain technological leadership position.
