Which one becomes the BEST general manager? A maintenance expert or a financial expert?

Having BEST in capital letters if not to highlight the word might mean an abbreviation, which I don't know its meaning. But if you are referring to best as a word, following is my answer:You can never say as you are not specifying the business, in General both can be stars based on their study and track; these days a maintenance manager should be trained on finance and must grasp it, while there is no training for finance managers on maintenance other than product knowledge. This leads to a maintenance manager with finance knowledge will be the best GM. Regards Sami

A GENERAL MANAGER SHOULD HAVE MORE FINANICIAL CABILITIES THAN MAINTENANCE.

General manager will be focused more in managment so I think the financial profile will be the best one to cover the position.

Maintenance profile with good background of operations of industrial equipment and machinery

Maintenance profile with with exeriance from a well known back ground 

no much knowledge is need for GM  about machines and details of technical  aspects of the plant , but many financial points are to be well cared  by GM 

This is a trick question. You require a confluence of multiple profiles to be "The Best General Manager"

But if I were forced to choose, I would lean towards a maintenance profile.

Maintenance profile which is totaly control in industry best

sales engineer is deal with the clients to sale the product and conveince much more to client. the service engineer is that which maitaine the states of working machine ..

A maintenance manager is qualified to fill the general manager's position more than a finance manager because the maintenance manager's job is to solve problems and maintain other issues. Moreover, a maintenance manager has the know-how of dealing with costs to reduce breakdowns with minimum efforts. 

For me its a maintenance profile
