Ventajas
Teradata invented much of what we now take for granted around distributed systems for structured, enterprise data. 1. As a result, there are still a lot of smart people hanging around the halls to bump into and learn from. 2. An enterprise data warehouse is a very sticky product. They aren't ripped out casually -- or often -- so the company still has a great client list of some of the world's most influential companies. 3. There will continue to be opportunities for talented people to take on new leadership roles... especially as so many existing leaders flee the company.
Desventajas
1. Wow, what a terrible culture. Combine the "us-vs-them" of a legacy product company with the inevitable decline of a legacy retailer. Like if Sears kept insisting they're really going to put it to those Walmart punks. So I bet you're not surprised that you're just as likely to be attacked as appreciated for suggesting new solutions, tools, languages, etc. 2. A new logo or name for your one product won't hide declining revenues and stagnant product development for long. 3. With all the disruption hitting this company, how is it possible that they promoted a guy who has never owned a P&L to be CEO?
