“We need a digital strategy to map out our roadmap to success”
“We’ve got to use <insert Content Management System / Product> because we’ve paid for licences for it”.
No you don’t.
You need to think about the what, then just get going on the how.
To overuse the metaphor, you need to stop thinking you need a horse and a cart. Don’t spend your time designing the cart, or worse still putting it in front of the horse. You’ll never get anywhere. Your horse will be perfectly good to get you started on the journey. If it is an old nag you won’t have invested much time and effort on designing a cart that’s not fit for the horse. And if it’s a thoroughbred you can build a cart that is fit for the journey when you need it. And that roadmap? What use is it in uncharted territory?
