So there you have it, the three parts of Invisible Communications, the factors that explain why people buy:

Trigger - How will we get them to think about us at the
right time
?
Frame - How will we get them to decide in our favour — the
right decision
?
Fuel - How do we keep the success going — the
right way
?
Easy say, but hard to do. Just remember, how people think they communicate often isn’t actually how they actually communicate.

Hopefully the above was a little taste into the hidden drivers that make people buy.
