This topic seems to require some clarification, as both frameworks identify components, draw connections between them and then can be used to do some sort of manipulation.
Key difference is in the focus: Porter emphasises efficiency. it’s all about doing exactly the same activities faster and cheaper, Wardley emphasises the purpose, which means understanding the landscape (what is the environment and how it is going to change) and what we are going to do about it. Only then comes the analysis of what is necessary to get things done, and after that, what is needed to get things done effectively and efficiently.
It’s analysis on a completely different levels of abstraction. Thoughts?
