Pros
A career at ABB is what you make of it. If you have a great deal of drive and initiative, you'll be allowed to pursue any opportunities and/or roles you desire. My experience has been quite positive and I feel I've been given the opportunity to pursue any interests I have. Additionally, as someone who has held several different roles in different business units, it's great to be able to move around in ABB with little effort from a systems and IT perspective. Regardless where you are in the world and working for ABB, most of the IT systems are relatively the same.
Kontras
Any company of this size has communication challenges. In the past 5 years most of the boundaries within ABB have come down and improvements are being made. However, I firmly believe that any organization has room to improve its communication. I would like to see objectives set for the business as a whole so all functions are heading in the same direction and working towards the same goals. Too often it seems each factory, function or business unit has their own marching orders which conflict at times. As I mentioned earlier, it's improved considerably but still has room to grow if we really want ABB firing on all cylinders.
