business law A company diagnosis is a necessary component of any business strategy. Nevertheless its importance must be put into perspective. On one hand, economic systems are dynamic and situations can change rapidly, so the actors of these systems must continually adapt themselves to the new conditions and adjust their behaviour, needs and expectations accordingly. On the other hand, a manager cannot be sure that the chosen solution will be the best one, nor that the decision will be good. Foreword VIII Foreword Strategy is, by definition, a dynamic domain. A situation can be approached from multiple perspectives, and there is not always one sole solution to an issue faced by a company: numerous solutions may be possible, each having its own strengths, weaknesses, and efficiency. Thus, the diagnosis is just one element (among others) guiding the formation of a business strategy. This strategy aims to identify actions that, when implemented, will facilitate the resolution of actual problems. Finally, the decision-making process is the result of a discipline of mind, based on specific thinking processes and mechanisms.
