On its own it is, but I think the idea behind it is to quantify your goals with specific numbers and quantify how you intend to get there. For example, one way to increase sales by 20% might be to increase visitors to your website by 20%. But another method, if only 10% of visitors download your software, increasing that to a 12% conversion rate will also increase sales by 20%. Lifting downloads from 10% to 12% might be easier than finding 20% more visitors. By thinking in specific numbers, you can brainstorm different ways to achieve the goal and choose the method that is fastest / least effort.
