Answer a question about STRATEGIC INFORMATION SYSTEMS ( The Answer is only one page )

It took 19 years to build Knight Capital Americas LLC into the largest market maker on the New York Stock Exchange, but on August 1, 2012, it took only 45 minutes for the firm to be wiped out by an information technology (IT) problem: a change in the company’s software caused it to lose more than $450 million dollars in less than an hour. Although it was ultimately saved from bankruptcy when it was acquired two days later, the terms of acquisition were very unfavorable to the company’s shareholders.
