Matthew David Rubin in his recent books tells us that Digital Strategy planning requires broad business knowledge and digital marketing experience, including business startup experience. Startup experience is valuable because of the dynamic fast-paced culture of startups, which provides opportunity to be technically and creatively inventive and financially resourceful (a requirement for many brand campaigns).
Startups are often required to launch products and services; their small intense business teams quickly develop excellent cross-platform collaboration skills.
So in practice, the digital strategy planning process should mirror the coral reef: an environment where different forms of information and experience, such as media, ideas, digital and legacy media experiences, business operations, technology research (trend and non-trend types), and strategies should be integrated.
Your personal digital strategy center of excellence then becomes a complete resource toolbox for better and more insightful digital solutions and innovation.
