This applies to much more than product design. I see many Adwords accounts that are structured based on a best practices boiler plate format...but fail to consider how the structure will interact with decision making in the future, forcing poor budget allocation or worse, making proper optimization unfeasible. Having a very clear vision from the outset for how you will need to adjust and optimize in the future and building an account structure in format that aligns with those processes is often the difference between a very successful account and a mediocre account that only shows minor incremental growth...
