We compared Effenus Henderson's author brand and book presence with the most successful self-published leadership book of the last decade. Michael Bungay Stanier first published The Coaching Habit through his own company, Box of Crayons Press, and grew it to 17,232 Amazon ratings and a #1 Best Seller badge. Both authors are consultants who teach leaders through a named framework — the difference is how the book is marketed.
Brooks Craft scores twelve areas that decide whether an HR leader or executive finds, trusts and buys a self-published leadership book. Each is rated from what is live today.
Scores are Brooks Craft Publishing's assessment. Every figure on this page comes from live pages captured on November 7, 2026.
Each pair was captured the same day, at the same size. Effenus is on the left, Michael Bungay Stanier on the right.
Both authors have an "Author" Knowledge Panel. Bungay Stanier's shows a Books carousel of six titles, two YouTube interviews, his website and LinkedIn and TikTok profiles. Effenus's shows photos and LinkedIn videos, but no books, and its overview still reads "Chief Diversity Officer for Weyerhaeuser" — a role he left in 2013.


The Coaching Habit gets a full book panel with ratings from Goodreads (4/5), getAbstract (9/10) and Audible (4.3/5), and "Read now" buttons for Kindle, Audible and libraries. SPINE returns plain links with no panel.


MBS Works ranks first for his name with a personal headline — "Hey there, I'm Michael Bungay Stanier AKA MBS" — and brings books, courses and keynotes together in one place. henderworks.com presents the firm rather than the author, with no photo of Effenus and no books in the main menu.


Bungay Stanier's Author Store shows a photo, bio, 36 titles and 17,232 ratings on his flagship. Effenus's books show no ratings at all.


Both books started as self-published titles, so both authors control the same tools. Bungay Stanier uses every one of them.
The Coaching Habit carries a "#1 Best Seller" badge, 7 videos, four formats and a description listing the framework's questions. SPINE has no ratings, no ebook, and a reading age of 15–18.


Bungay Stanier's A+ Content is a branded comic: the author explains in three panels why the book works, then a comparison chart sells four more of his books with ratings and prices. SPINE has no A+ Content and an empty "Upload your video" box.


The Coaching Habit is #1 in Business Mentoring & Coaching, #5 in Human Resources and #14 in Leadership & Motivation — exactly the shelves an HR or DEI book should be on. SPINE ranks #721 in Business Diversity & Inclusion.


The Coaching Habit's Kindle page carries endorsements from Brené Brown, Daniel Pink, Dave Ulrich, David Allen, a New York Times executive and Kirkus. SPINE has no Kindle edition, so it has no Editorial Reviews section at all — even though Effenus's peers at ISO, SHRM and Fortune 500 companies could supply exactly this kind of endorsement.


Corporate buyers order leadership books in bulk through bookstores. The Coaching Habit is stocked; SPINE is Amazon-only.
Barnes & Noble returns a 404 for SPINE's ISBN — the book is not in their catalogue. The Coaching Habit is in stock and can be found in stores.

Bungay Stanier proved a self-published leadership book built on a simple framework can reach a million readers. Effenus has the stronger credentials — this is the same playbook, built around them.
Brooks Craft Publishing will build the visibility the SPINE trilogy needs to stand beside the most successful self-published leadership books.
