Avantages
Global structure, worldwide matrix organization, in case of proper management support, you can find your way to go ahead and to be promoted. Best in class! Support of good ideas. (If!) Diversified portfolio, omnipresence in each industry. Many professional people all around. Lot of available resource globally. Excellent high level corporate concepts, strategies and values.
Inconvénients
At a certain manager level too many politicians. Old style ones are chasing short term targets on anyway (i.e: current budget, mainly in terms of LC) They are going to keep their chairs for few years, especially before retirement and as a consequence they do not take a risk to invest in the future growth. They are blocking to broadcast many good ideas to the upper level management. Immediate re-organisation even for interim business drop. Lack of synergies between business lines. Very slow decision making! (From initial ideas till approval/refusal). The structure is not well prepared to integrate the new concepts, business styles, ideas, but they broadcast permanently: think out of box! You can be the best up to a certain level for many years, but above it you can be evaluated on different way by loosing your achievements and recognitions from the past within a minute.
