Buyer Experience Cycle
Andrew Nelson, CEO, Australia
The six stages you list are just a guide. They represent a typical cycle for a B2C product. But it is important to firstly customise this list to the special circumstances of your product, service or business.
For example, when working with B2B products and services we often find that it is helpful to explore more initial steps than simply "Purchase", because the purchase is usually quite complex and may involve many stakeholders of different kinds.
In fact, in any case where there is more than one person involved in the purchase (e.g., influencers and end users) it may be necessary to codify the experience cycle that each important stakeholder goes through.
