Back in early July, enterprise software company Compuware (NASDAQ:CPWR) gave Wall Street a jolt. The stock price plunged 20% on a weak sales forecast, and the company's president, Hank Jallos, resigned. Now, about half of the sales force may get pink slips.

According to last week's earnings announcement, Compuware's fiscal first-quarter revenue fell 5.7% to $279.4 million, and license revenue was off 29% to $47.2 million. License revenue is critical, since it generally leads to ongoing maintenance and service fees.

Net income was breakeven, and cash flows from operations came to $37.8 million. The company has about $339.4 million in the bank.

One bright spot is Compuware's Covisint division, which helps manage supply chains for customers such as General Motors (NYSE:GM), Johnson Controls (NYSE:JCI), and CIGNA (NYSE:CI). First-quarter revenue here increased 49.3% to $9.87 million, and there was a profit of $630,000.

But as Compuware's CEO, Peter Karmanos Jr., said on the conference call, the sales team "faces a serious sales-execution problem." He even apologized to his shareholders. While he plans to attack the problem quickly, the solution will be far from easy. It often takes nine months to get a sales force productive.

In the meantime, rivals such as IBM (NYSE:IBM), BMC (NYSE:BMC), and Hewlett-Packard (NYSE:HPQ) will likely capitalize on the situation. It could ultimately lead to even more revenue deterioration.

As I noted in an earlier column, there was a good amount of buyout buzz recently surrounding Compuware. And a deal may eventually happen. But in light of the problems at the company, there probably won't be much of a premium.
