I think employees are a lagging indicator. If the product is being offered at all, look at customers. If you're not customer-facing, talk to a customer-facing engineer or even account manager. "How's the X account?" "Tell me about a customer we've made successful." Don't accept "The account is fine." Drill down and ask for details; they're the only things that matter. You're internal, so unless your company is really $&#+ed up and silo'd, you shouldn't have a problem getting a feel with a modicum of social skills. If you're not making customers happy, and management is proceeding with business as usual, start looking for a new job.
