Marissa Mayer tells Yahoo employees products must ship in six months

Ask any ex-Yahoo employee what's wrong with the company and one of the first three things they'll tell you is that the place is too slow.

Too slow to figure out what to do. Too slow to do it.

After two months on the job, Yahoo CEO Marissa Mayer is aware of the problem.

On Tuesday, she gathered all Yahoo employees for an all-hands meeting to announce her turnaround plan for the company.

According to sources familiar with the details of the meeting, one of her major changes to Yahoo is how the company will decide which products to ship.

Mayer's rule: If a new product can't be shipped in six months, and if it doesn't have a realistic shot of reaching 100 million users or generate $100 million toward the company's top line, then Yahoo will no longer bother.
