In a move designed to bring top management decisionmaking closer to local customers, International Business Machines Corp. has formed an Intermountain Regional office to be located in the IBM Building, 420 E. South Temple.

"Creation of this new region is a continuation of IBM's efforts to become more efficient and responsive to customer needs," said Robert M. Egan, recently named regional manager."By centralizing our executive responsibilities we will be able to make major decisions faster and nearer to the business operations involved, currently a major strategic objective throughout IBM," he said.

The new region includes Utah, Idaho, Montana, Alaska, eastern Washington and northwest Wyoming. There are 500 employees in six branch offices: two in Salt Lake City and one each in Boise, Helena, Mont., Spokane, Wash., and Anchorage, Alaska.

Egan has worked for IBM for 17 years and previously was southern area manager of mid-range and end-user marketing in Atlanta, Ga. Since joining IBM he has held a variety of marketing and management positions.
