Pros
If you are in favor and have a senior leader backing you, BBY is very proactive at development. The leaders (Brad Anderson and Brian Dunn), I believe, are very ethical and committed to their employees. There are many smart people and a commitment to creativity.
Cons
Best Buy is split into four groups: Retail, Corporate, Consultants and Subsidiaries. The retail group is dominated by excessively competitive types who regularly violate their own ethical code to achieve career objectives. There is a great deal of hubris in this area and it will eventually lead BBY to ruin if left unchecked. The Corporate group are smart and capable, but for the most part also obsessed with whether they will be around in a month and their next career move. Senior leadership inked a deal with Accenture that gave too much control of key operational areas to a single entity, leading to a predictable level of conflict between expectations and deliverables. The integration of BBY's subsidiaries have been a failure, largely due to the lack of an effective merger and acquisition strategy, and the unchecked interference by one or all of the other groups above.
