In recent years, in order to become industry leaders, many companies have invested heavily in building IT systems, and firmly believe that this will bring rich returns. But the result is often disillusionment, and efforts will only lead to failure. More than half of the investment is in the so-called "complete information technology", or information technology that can be used in the whole business process of the enterprise, rather than the technology aimed at a single task.
Case studies in many aspects show that 30%-75% of new IT systems failed to meet expectations, did not generate obvious profits, did not improve workflow or brought new changes in organizational structure. In some cases, the result is even catastrophic. For example, Nike once spent hundreds of millions of dollars to develop a system for forecasting sales, but the results were very inaccurate. Hershey Food Company missed the Halloween sales season because it didn't have enough candy stocks in major retailers. FoxMeyer Drug filed for bankruptcy at least partly because of problems in ERP implementation.
