This document outlines a business seminar on Porter's 5 Forces model. The seminar will recap Porter's 5 Forces, examine a case study of Brompton Bikes, and have students conduct an analysis of Brompton Bikes using the 5 Forces model. Students will then analyze the competitive environment of a hypothetical new business they invent using the 5 Forces model. The goal is for students to understand how to identify and assess competition in an industry using Porter's 5 Forces of suppliers, buyers, potential entrants, substitutes, and industry rivalry.

7. Using Porter’s 5 Forces Model
• You will have read the case study
• You’ve seen one video – here are a couple more to provide a bit more background:

in-Britain.html
• http://www.telegraph.co.uk/finance/good-news/9482163/Brompton-boss-Will-
Butler-Adams-bicycles-are-beating-the-downturn.html

8. Now do the work …
• Using all the information you have, you now have 20 minutes to carry out an
analysis of Brompton Bikes against the 5 Forces Model
• Be prepared to present your ideas to the group, and for others to challenge or
question some of the assumptions and assertions you make

9. Now finally – to reinforce your understanding
• You are starting up a new business – you want to assess its position as regards
competition
– Choose the business (what will you sell, where will you sell it)
– Decide how your business fits in with the competition you face
– Make some immediate recommendations as to how you will make YOUR
produce competitive

10. To recap
• Porter’s 5 forces model is about the competitive environment
• You have used the model on a real case – Brompton Bikes
• You have used the model on a hypothetical case – your own business
• In lecture 2 we will be looking at the various ways in which businesses scan the
whole external environment – why they do it and what tools they use
