Question

Quizplus · Accepted Answer

The Answer is The determination of the best strategy relies among other factors on the analysis of the external environment of the firm.
This environment can be split into the general environment which comprises diffuse and general trends, and the industry environment which consists of the events and players that are closer to the firm and impact its activity more directly.
However, the general environment also has influence on the industry environment.
Therefore, a firm's analysts need a comprehensive framework that will help them to sort the variables by category, to distinguish the vital from the important, and to determine which trends and phenomena are likely to impact their industry and their activities. Frameworks allow us to classify, to understand the environment and to decrease the probability of missing something important.
Still, the exercise remains difficult and requires skills and experience in the industry.
