While there is a strong vision at the upper level, they have a false vision of what's truly going on at all levels. There is so much bureaucracy and an over-filled hierarchy that slows progress. Deadlines are continually pushed back as there is much tape to go through. Getting excited about any new technology or process is quickly forgotten in the midst of the challenges. You can see this in everyone's eyes when you tell them about new improvements - they'll just roll their eyes. Throughout this process, the upper management is told that everything is going well when the people lower in the hierarchy see nothing different than business as usual.
Furthermore, moving around in the company is rather difficult. Positions open and you never hear anything until months later. Typically, the position will never be filled. This has happened at least 20 times (no exaggeration) with me and several other employees. Also, the pay ranges have been restricted and many people haven't seen raises for years, or minimal raises. Many people don't think they're being paid what they're worth.
