Content Marketing Optimisation - presentation

To try and explain both the alignment of the typical website delivery process (engage, specify, design, develop, test & launch) with the approach needed to deliver website content, I put the presentation below together.

Both processes need to closely align, but then once content it delivered it needs to be updated in a cyclical process. This content marketing optimisation approach need to factor in not just the brand (e.g. values, voice, etc.) but also other considerations such as the relevant SEO terms to target.

As always, the presentation is a 'straw man' and I'd value any feedback anyone has on this.
