Positioning, as DemandOS defines it
Positioning is not what you say about yourself; it is how the market hears what you say. Buyers categorize an agency quickly based on options they already understand. If you do not fit a recognizable construct, they forget you.
That is why the DemandOS process defines position before anyone writes a word. Your case studies, your team's content and your sales conversations all need to point the same way, or the market will believe the work over the tagline.
