(AAB9)求教AA-B9思路（讨论链接里的题号和内容对不上）谢~

B9.The following appeared in a memorandum to a team developing accounting software for SmartPro Software, Inc.:

“Currently, more professional accountants use SmartPro accounting software than any other brand. However, in the market for personal accounting software for non-professionals to use in preparing their income tax returns, many of our competitors are outselling us. In surveys, our professional customers repeatedly say that they have chosen SmartPro Software because our most sophisticated software products include more advanced special features than competing brands. Therefore, the most effective way for us to increase sales of our personal accounting software for home users would clearly be to add the advanced special features that our professional software products currently offer.”

只能挑出一点来：professional customers 觉得好的home users 不见得觉得好，功能太复杂，价格就贵，home users 也用不到那么多功能，他们要实用的，实惠的

其他的望指点指点~谢谢！

其实你已经挑出两点了：

错误类比和静止假设。就是增加功能后价格也会升高因此销量会受影响

还有一点就是其他场上买的原因也许是他们有独特的手段：广告，外观，售价。

1.Doubtful survey

2.False analogy

3.Gratuitous assumption (- competitors are outselling software for non-professionals may be due to other reasons rather than special features)

4.One sideness (-add the advanced special features will add production cost) + Gratuitous assumption (- competitors are outselling software for non-professionals may be due to other reasons rather than special features)
