Inventory theft was perceived as the second-most frequently occurring fraud. On pilferage in the infotech industry, P. Gandhi, director, Integra Tech soft, says: "In the computer business, pilferage by the engineers and technical staff is often most difficult to detect." Computer parts like motherboards, floppy drives and memory modules, for example, can be easily smuggled out and, despite the best inventory control practices through streamlining approvals, a foolproof system may be elusive. There is also the problem of discounts and commissions that marketing and sales personnel may pocket. "At the time of upgrading a machine, local spares are easily substituted for branded ones and we do it routinely. That's the only way to keep margins high," says a nonchalant dealer for another leading computer firm.
