每日原则：使用顾问要明智，防止过度依赖顾问

有时候，为了更好地进行设计，你需要雇请外部顾问，你可以由此获得所需的大量专业技能来解决某个问题。当你把任务外包时，你就不必担心管理的问题，这是个实实在在的优势。如果某个职位不是全职的，且需要高度专业化的知识，我宁愿交给顾问或外部人。

但同时，你需要当心不要太过频繁地雇用顾问来完成本该由员工承担的工作。这会使你迟早付出代价，也不利于维护你公司的文化。你还要确保不要让顾问换种方式做事。他们几乎肯定还要按照自己惯常的方法行事，他们的老板也会要求他们这样做。

Sometimes hiring an external consultant is the best fit for your design. Doing so can get you precisely the amount of specialized expertise you need to tackle a problem. When you can outsource you don't have to worry about managing, and that's a real advantage. If a position is part-time and requires highly specialized knowledge, I would prefer to have it done by consultants or outsiders.

At the same time, you need to beware of the chronic use of consultants to do work that should be done by employees. This will cost you in the long run and erode your culture. Also make sure you are careful not to ask consultants to do things that they don't normally do. They will almost certainly revert to doing things in their usual way; their own employers will demand that.
