Organize around the decision, not the org chart.
The direct answer
Structure the site around the real decision a visitor is trying to make — not around your org chart or a generic service list. Most websites are organized the way the business sees itself; the ones that actually convert are organized the way a visitor's decision actually unfolds.
The shape of a real decision
Across very different industries, the pattern repeats: a visitor needs to understand the situation, compare real options, sometimes calculate a real number, then decide and take action — or, in a more relationship-driven context, get found, get understood, get contacted, and get followed up with. Either way, the site's structure should mirror that path, not fight it.
Real examples
AgingParentsHome.com is built around exactly this decision path for adult children weighing care options. The Wonderful Blessed Care site separates family, referral, and career decisions into distinct paths rather than one generic funnel. Both are the same underlying principle applied to different audiences.
