Porters Five Forces is a model designed to help us quickly and effectively analyse the market in which our business operates.
It provides a framework for us to conduct our market research and ensure that we have considered the key competitive factors that may impact on our business.
By ensuring that we are aware of these 5 factors it will help to identify what we need to consider when building a business / marketing plan and help with developing key strategies in which to grow.
For a quick explanation of Porters five forces watch the 2 minute video from Harvard business school which focuses on the airline industry
Porters Five Forces – evolved
However in the real world not all of Porters five forces are not the same for every business
For example if the market you are entering has many substitues i.e. if you won a bowling alley then substitues maybe be all other entretianment within the area i.e. cinemas, pool halls, golf ranges, restaurants, theatres – then this box mybe big.
However if there are many suppliers of bowling balls and pins i.e. more than 10 companies then the supplier power maybe weak and you have many places where you can buy your product supply from, this would mean the supplier power box will be small. As a result more of your resources should be focused on competing with substritues i.e. marketing plan.
The smaller the box the weaker the forces thus the less resources required to work on it, thus the larger the box the stronger the force and the more resources / focus should be dedicated to considering it.
Draw your own Porters 5 Forces ensuring that you draw the boxes to the size relative to your business.
Question: What does this tell you , where do you need to focus your energy ? Is there fierce competiton? How powerful are your buyers , how many substitutes are there ?
Remember the bigger the box the more challaning this force will be.
