Research Report: Leadership Literature Landscape for Wild Dogs Leadership

Deep-research output (web-verified June 2026) backing course/course-design.md. Raw reference material — pricing figures flagged where sources conflict.

TASK 1 — Author/Framework Landscape: Complements to Maxwell + Lencioni

Organized into tiers by fit with Jer's ethos (soul formation, sacrificial service, team, resilience, ripple-out impact, crock-pot formation).

TIER A — Direct soul/character/formation fit (strongest matches for "Soul of the Leader")

1. Robert K. Greenleaf — Servant Leadership

2. Ruth Haley Barton — Strengthening the Soul of Your Leadership (2008; expanded ed. 2018, IVP)

3. Parker Palmer — Let Your Life Speak (2000); A Hidden Wholeness (2004); essay "Leading from Within"

4. Henri Nouwen — In the Name of Jesus: Reflections on Christian Leadership (1989)

5. Pete Scazzero — The Emotionally Healthy Leader (2015); Emotionally Healthy Spirituality (2006)

6. Dallas Willard — Renovation of the Heart (2002); The Divine Conspiracy (1998); with Gary Black, The Divine Conspiracy Continued (2014)

7. J. Robert Clinton — The Making of a Leader (1988; rev. 2012, NavPress)

8. David Brooks — The Road to Character (2015); The Second Mountain (2019); How to Know a Person (2023)

TIER B — Character/service grounded with research or business credibility (bridge both courses)

9. Jim Collins — Good to Great (2001), esp. Level 5 Leadership; Great by Choice (2011)

10. Jim Loehr & Tony Schwartz — The Power of Full Engagement (2003); Loehr, Leading with Character (2021)

11. Brené Brown — Dare to Lead (2018); Daring Greatly (2012)

12. Liz Wiseman — Multipliers: How the Best Leaders Make Everyone Smarter (2010; rev. 2017)

13. Adam Grant — Give and Take (2013)

14. Edgar Schein — Humble Inquiry (2013; 2nd ed. 2021); Humble Leadership (2018, with Peter Schein)

15. L. David Marquet — Turn the Ship Around! (2012)

TIER C — Evidence/skills ballast & additional candidates

16. Kouzes & Posner — The Leadership Challenge (1987; 7th ed. 2023) — Five Practices (Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, Encourage the Heart) from 5M+ LPI responses and 30+ yrs of data; Credibility (1993/2011) and A Leader's Legacy (2006) hit character. The research-grounded structural twin of Maxwell's 21 Laws — Body course backbone if Jer ever wants a validated spine. Also The Truth About Leadership (2010): "leadership is everyone's business... and it's an inside job" — bridges to Soul. Body.

17. Frances Frei & Anne Morriss — Unleashed (2020) — Trust triangle (authenticity, logic, empathy; identify your "wobble"); thesis: leadership is "about empowering other people as a result of your presence — and making sure that impact continues into your absence." That sentence is practically the Wild Dogs mission statement; her TED talk on trust is a free course asset. Body, with Soul implications.

18. Bill George — True North (2007; Emerging Leader Edition 2022, with Zach Clayton) — Authentic leadership: crucible stories, "I-to-We" transformation (his name for the self→others shift), True North as internal compass, support team/personal board of directors. Ex-Medtronic CEO + Harvard. The crucible-story exercise is a proven Soul-course staple. Soul/Body bridge.

19. Ryan Holiday — Ego Is the Enemy (2016), The Obstacle Is the Way (2014), Stoic Virtues series (2021–2025) — Stoicism popularized; ego as the leader's chief inner enemy; four cardinal virtues as character curriculum. Secular character-formation language for clients allergic to anything spiritual; resilience-native. Soul (secular track).

20. Amy Edmondson — The Fearless Organization (2018); Right Kind of Wrong (2023) — Psychological safety (Harvard, 25+ yrs of research; the construct behind Google's Project Aristotle #1 finding). The scientific underpinning of Lencioni's trust/conflict dysfunctions; her 7-item psych-safety survey is free/public domain in the research literature. Body (team diagnostics).

21. Marcus Buckingham — First, Break All the Rules (1999), Now, Discover Your Strengths (2001), Nine Lies About Work (2019) — Gallup strengths lineage; "people don't leave companies, they leave managers"; strengths-based development. Useful Body-course module + CliftonStrengths pairing; weakest soul-fit of the list (strengths language can feed the self-advancement frame Jer critiques — use deliberately as "strengths in service of the team"). Body.

22. Others worth knowing, lower priority:


TASK 2 — Critiques of Maxwell-Style Content & Research-Grounded Complements

The critique (documented):

  1. Anecdotal, not empirical. Reviews of 5 Levels note principles "lack scientific basis... based largely on anecdotal evidence and Maxwell's own experience" as a pastor; heavy on what, light on how; repetitive across his ~90 books (Shortform review). "Irrefutable" is a marketing claim, not a tested one.
  2. The leadership industry critique generally. Jeffrey Pfeffer (Stanford), Leadership BS (2015): most leadership wisdom is "based more on hope than reality... on beliefs instead of science," and the $20B+ industry hasn't moved engagement or leader-failure numbers (Stanford GSB). Barbara Kellerman (Harvard), The End of Leadership (2012): the industry is "self-satisfied, self-perpetuating and poorly policed." Note: these critiques cut for Jer — they indict event-based, self-advancement leadership-as-commodity, i.e., exactly the dilution he names. His crock-pot/cohort/formation model is the structural answer (research on training transfer consistently favors spaced practice + coaching over one-off events).
  3. Success bias / halo effect. Phil Rosenzweig's The Halo Effect (2007) is the standard methodological critique of great-leader storytelling (applies to Collins too, worth knowing honestly).

Research-grounded ballast to pair with Maxwell:

Evidence base What it validates in Jer's program
Kouzes & Posner LPI — 5M+ respondents, 30+ yrs, 700+ dissertations, Cronbach's α > .75 A validated behavioral spine for the Body course
Google Project Oxygen (10 manager behaviors; coaching & empowerment top the list) Supports Level 4 People Development. re:Work
Google Project Aristotle (180 teams; psychological safety #1 of 5 dynamics) Empirical twin of Lencioni's pyramid
Amy Edmondson — psych safety construct, 25 yrs peer-reviewed The "how" beneath Dysfunctions #1–2
Gallup — Q12 meta-analyses (100k+ teams); manager explains ~70% of variance in team engagement "Leader changes team changes org" ripple, quantified
Collins' Good to Great method (1,435 → 11 companies) Quasi-empirical case for humility + will
Crossan/Ivey Leader Character research (300+ senior leaders; LCIA; character–judgment–performance links) Academic validation of character/soul as performance driver
Adam Grant's giver research (Wharton field studies) Sacrificial ("otherish") giving as long-run winning strategy
Wiseman's Multipliers research (150+ execs, 2× capability) Anti-diminisher, team-multiplying leadership
Servant leadership meta-analyses (e.g., Eva et al. 2019, Leadership Quarterly) — links to team performance, OCB, lower burnout Greenleaf isn't just inspirational; it measurably works

Positioning takeaway: Jer doesn't need to drop Maxwell — he should triangulate: Maxwell (accessible language) + one validated instrument (LPI or psych-safety survey) + one research narrative per module. That directly rebuts "anecdotal" without losing warmth.


TASK 3 — Assessments/Instruments & Pricing

Instrument What it measures Pairing Cost/licensing (as found)
LPI 360 / LPI Self (Kouzes & Posner, Wiley) 30 behaviors across Five Practices; self + observers Body course pre/post (re-takeable — shows growth over 15 months) ~200individualviadistributors; LPISelfcheaper50 range historically); no certification required to administer. i-lead.com
Six Types of Working Genius (Lencioni/Table Group) 6 work geniuses Natural add since Jer already teaches Lencioni; team map exercise **25–35/person * *; certification 1,500–2,500; facilitator license ~$500/yr. workinggenius.com
Five Dysfunctions Online Team Assessment (Table Group) 37 statements vs. the 5 dysfunctions; team report Direct fit for Soul course teams $56.50/license/person; no certification needed. tablegroup.com
CliftonStrengths (Gallup) 34 talent themes Body course module (frame as strengths-in-service) Top 5 ~59.99, All34 99.99; coach certification ~$7,000+. gallup.com
iEQ9 Enneagram (Integrative Enneagram Solutions) Type, subtype, centers, integration — framed for coaching/leadership Premier "soul-adjacent" instrument Practitioner accreditation ~1, 950(ICFaccredited); reportsoftenbundled 350 test+debrief. integrative9.com
Leadership Circle Profile (LCP) 360 Creative Competencies vs. Reactive Tendencies — links "inner game" to outer behavior THE assessment whose theory matches "change the inside to change the outside" (Kegan-based) Certification required (~$2,000–3,500); per-profile a few hundred USD. leadershipcircle.com
LCIA (SIGMA/Ivey) Crossan's 11 character dimensions, self + 360 Character-based Soul metric with academic pedigree Via SIGMA; pricing on request
Psych safety survey (Edmondson 7-item) Team psych safety Free public-domain items; Fearless Organization Scan = paid version Free / paid scan
GiANT 5 Voices / GiANT OS Voice order + 70+ visual tools Competitor-adjacent toolkit; licensable GiANT OS Pro ~$10/user/mo. giantuniversity.com
DiSC / MBTI Behavior/personality styles Commodity; skip unless clients ask ~$50–80/report

Practical note: cheapest credible stack = Working Genius (25) + FiveDysfunctionsOTA(56.50) + free Edmondson items + LPI for the Body course. LCP is the aspirational soul-aligned premium add. iEQ9 is the best soul-depth-per-dollar single inner-life instrument.


TASK 4 — The "Leadership for the Soul" Commercial Niche

Notable players:

White space (observed in the landscape above): Soul-formation programs (Transforming Center, Arrow) serve pastors/ministry, while team-effectiveness programs (Table Group, GiANT) serve the marketplace but stay above the waterline of the soul — Townsend is the nearest hybrid, but institutional/degree-shaped rather than boutique/relational, and nobody in either camp pairs soul claims with research evidence. Long-arc cohort formation remains rare because it doesn't scale, even though event-based training measurably fails (Pfeffer/Kellerman). One caveat: the Enneagram-and-formation space is crowded at the low end, so differentiation rests on the team + senior-leader + longitudinal dimensions — and on the wild-dog pack metaphor (hunt as team, feed weakest first, ~80% hunt success vs lions' ~25–30%), brand language no competitor uses. (The positioning conclusions drawn from this landscape live in the Strategy Brief.)


  1. Greenleaf, Servant Leadership — canonical "feed the pups first"; the "best test" belongs in the flagship verbatim
  2. Barton, Strengthening the Soul of Your Leadership — shares the course's literal thesis; model for crock-pot soul formation
  3. Collins, Good to Great — Level 5 humility+will as empirical spine for sacrificial leadership; Stockdale = Resilient
  4. Loehr & Schwartz, The Power of Full Engagement — body→spirit pyramid unifying both course names
  5. Palmer, Let Your Life Speak + five shadows — "inner world changes outer world," quotable, faith-adjacent
  6. Wiseman, Multipliers — Accidental Diminisher = best senior-leader mirror exercise in print
  7. Brown, Dare to Lead — research mechanism beneath Lencioni's trust pyramid; free workbook/values tools
  8. Grant, Give and Take — data proving "otherish" sacrificial leaders finish first
  9. Clinton, The Making of a Leader — lifetime-stages model; timeline exercise for session one
  10. Crossan/Seijts/Furlong, The Character Compass — academic validation that character is developable and drives performance
  11. Scazzero, The Emotionally Healthy Leader — inner/outer two-track structure mirrors his two courses
  12. Kouzes & Posner, The Leadership Challenge + LPI — the validated instrument answering "Maxwell is anecdotal"
  13. Edmondson, The Fearless Organization — psych safety science under Dysfunction #1; free survey items
  14. Brooks, The Second Mountain — secular vocabulary for the self-advancement critique; marketing goldmine
  15. Nouwen, In the Name of Jesus — 80-page depth charge on relevance/popularity/power (Soul, optional deeper track)

Honorable mentions: Marquet (delegation), Schein (mutuality practice), Frei (trust triangle), Bolsinger (Resilient with formation depth), Holiday (secular-Stoic track), Quinn (Deep Change).
