One of the benefits of making an acquisition has to be that duplicated positions can be eliminated, and NCR Corp has had to tell a total of 284 employees at two Teradata and two NCR locations in Southern California that they are surplus to requirements. The cuts affect people in engineering, manufacturing and administrative support, the largest lay-off reportedly coming at Teradata’s El Segundo base, where the payroll falls to 600 from 775. Also affected are NCR’s Rancho Bernardo engineering and manufacturing base and its Torrey Pines development centre, and Teradata’s Sharbase manufacturing site. Teradata chairman Kenneth Simonds, who joined from Amdahl Corp in 1984, handed in his resignation and quit.
