As a freelancer, when I first begin working for a company, I can sometimes be asked to deep dive into building full-scale marketing strategies.
In reality, I find it takes some time to understand an organisation, what makes it tick and who its fans and audiences really are. Finding mutually beneficial workflows with strategic goals at the outset could be a good interim measure.
Positively deciding on developing strategies after a few months based on a deeper experience and knowledge can make strategic planning more effective, rigorous and easier to implement.
