In certain companies, mostly those that have an IT heritage (see http://www.svpg.com/blog/files/moving-from-it-to-product-organization.html), there may be an additional role somewhere in the product organization either in product management or in the product development organization that may be called 'Business Analyst.'
Many of you probably saw that eBay recently had a lay-off, and given the condition of the economy they are not likely to be the only one doing so. What I wanted to talk about in this article was what to do if you find yourself in the same boat.

Occasionally a company starts its life as one type of business but then finds that they need to change into another type of business. The most common such transition I see is to start by building products for very large companies (enterprises), but then decide you need to switch (or expand) to sell to consumers and/or small businesses.
