They are different.
- Strategy presentation. In most cases, the audience of a strategy project recommendation presentation understands the context. A large part of them probably participated in the project (steering committee meetings, interviews, doing analysis). Therefore, the presentation can be highly in your face, conclusions upfront, in a strict logical order. Pretty much like the classic consulting presentation.
- Sales presentation. Your audience will be less familiar with the background, you need to drag them in a bit slower, show that you understand their problem, etc. And, logic only is unlikely to lead to a sale.
