Why Lencioni and StoryBrand Books Need Real Interior Design

Patrick Lencioni's The Five Dysfunctions of a Team and Donald Miller's Building a StoryBrand are different books that share a structural pattern. They teach a framework. They use diagrams to anchor the framework. They use sidebars to hold case studies. They use pull quotes to keep the eye moving.

That pattern requires custom interior design. Vellum, Atticus, Reedsy, and Kindle Create are the standard tools for indie publishing in 2026, and none of them produce framework-book interiors that hold up under a side-by-side comparison with the Big Five business titles.

What custom interior design does that template tools don't:

• Diagrams that match the book's typography. A diagram drawn in Adobe Illustrator using the book's chosen fonts and color palette reads as part of the book. A diagram exported from Lucidchart and dropped into Vellum reads as a slide deck.
• Sidebars that breathe. Templates put sidebars in a generic gray box. Custom design places them with intentional whitespace, custom rules, and typographical hierarchy that holds the reader's attention.
• Pull quotes that anchor pages. The placement and typography of pull quotes affects how readers scan a chapter. Custom design treats this seriously.
• Chapter openers that establish rhythm. A framework book typically has a recurring chapter structure. Custom design treats the chapter opener as a recognizable visual signature.
• Headers, captions, and footnotes that match. Templates use generic Helvetica or Garamond. Custom design picks the typeface that matches the book's argument.

What this costs: $4,000 to $15,000 for full custom interior design on a 200-page business book. The wide range reflects how much diagram work is involved and how complex the chapter structure is. A book with 15 frameworks and 30 sidebars takes substantially more design hours than a straight narrative business book with five sidebars.

The return: the book reads professionally on first contact. A reader who picks it up at an airport store, a conference giveaway, or a lobby coffee table forms an impression in 30 seconds. A book with template interior design loses to a Big Five competitor in that 30 seconds. A book with custom interior design holds its own.

For business-book authors at the $30K-plus production budget tier, custom interior is one of the highest-leverage decisions. For authors at lower budgets, Vellum is fine. The line between "Vellum is fine" and "custom is necessary" is roughly: does your book teach a framework with diagrams and sidebars?
