As a business student you have likely spent some time learning about applications of PEST (and/or PESTEL), Porter's 5 forces, and SWOT analysis over the years. These are useful tools for understanding the environment in which a given organization might find itself embedded. SWOT analysis is useful for understanding the organization itself on a more micro-level scale.
Discuss to what degree you believe these tools are actually useful for different sized businesses. For instance, what should a mom and pop computer repair store consider doing in the area of strategic analysis? What about a medium sized retailer?
What about a family? Is there an optimal organizational size for applying these tools? Give some evidence to support your key points.
