The document outlines a proposed 5-layer model for corporate digital operations and engagement. The 5 layers are: 1) Core business processes, 2) Web services and APIs, 3) Owned media like websites and apps, 4) Paid media like online ads, and 5) Earned media like social media and word-of-mouth. The model is presented by Hayden Sutherland of Ideal Interface as an updated alternative to McKinsey's existing approach to conceptualizing a company's digital presence.
