“Digital transformation is a journey with multiple connected intermediary goals, in the end striving towards continuous optimization across processes, divisions and the business ecosystem of a hyper-connected age where building the right bridges in function of that journey is key to success. ”
(quoted by here)
Digital transformation historically refers to turning paper into digital information; namely the digitization of these documents into digital formats and into digital processes.

Change Management
Knowing the role of data and analytics in digital transformation, there are even more opportunities for change and needs for change management. 

Intent and Priorities
There is never a "one size fits all solution". Intent, outcomes and priorities steer the digital transformation efforts, as well as changing parameters in the ecosystem.

There are still far too many gaps in regards to the digitization (and automation) of existing processes and the digitization of data from paper carriers.

Silos, Responsibilities, and Skills
Digital transformation – just as social business, digital business and any form of customer-centric marketing and business processes, requires the ability to work across silos.
