Digital transformations fail. Responsibility for these failures often lands on the shoulders of a firm’s digital business and strategy (DB&S) professionals. With hindsight, the reasons why transformations fail are clear: Companies inadequately plan, insufficiently test, or ineffectively launch strategic digital initiatives meant to catalyze transformation. DB&S pros can improve digital initiative success rates by applying strategic and operational modeling to three stages of strategic activities: plan and draft, test and learn, and launch and optimize.
