Kilmann Diagnostics

What Kilmann Diagnostics does

Kilmann Diagnostics LLC is a privately held, founder-operated company founded in 2009 by Dr. Ralph H. Kilmann, the original co-creator of the Thomas-Kilmann Conflict Mode Instrument (TKI), a forced-choice psychometric assessment first launched in 1974 that measures five conflict-handling modes (competing, collaborating, compromising, avoiding, accommodating). The company sells TKI Individual Reports, Team Reports, and Inside/Outside dual assessments directly through its e-commerce website, with delivery infrastructure hosted on The Myers-Briggs Company's Elevate platform. It also offers a three-tier course curriculum (BASIC, GROUP, ADVANCED Training in Conflict Management) and a wider assessment portfolio that includes the Kilmann Organizational Conflict Instrument (KOCI), the Kilmann-Saxton Culture-Gap Survey, the Organizational Courage Assessment, and the Personality Style Instrument, plus an adjacent line of 'consciousness' and 'quantum transformation' courses.\n\nThe business model is direct-to-consumer, self-serve e-commerce with group-purchase functionality managed through a proprietary KD_Spreadsheet system. Pricing is low-ticket and transactional: individual TKI reports sell for $50–$100, courses range from $225–$500, and certification bundles (TKI Package at $875, Complete Program of 11 courses) anchor higher-priced recurring purchases with multi-month access periods. Quantity discounts scale down to $45/person for large groups. The customer base spans individual professionals, established workgroups, organizational L&D buyers, certified practitioners, and educational institutions, with named enterprise usage including Microsoft, Google, Nvidia, McKinsey, Deloitte, Bank of America, Harvard, NASA, the US Army, and the World Health Organization.\n\nThe firm is bootstrapped with no disclosed external funding, operates with approximately 4 team members, and runs on a founder-led content-marketing model leveraging Dr. Kilmann's authority as co-creator, supported by a substantial library of books, articles, blogs, and videos. The TKI is a registered trademark, available in 10+ languages, with norms updated in 2007 based on 60,000+ assessments from 59,000 respondents, and 10+ million cumulative profiles sold worldwide since 1974.

The company also delivers recorded online training courses (BASIC, GROUP, ADVANCED), bundled certification packages, and complementary organizational assessments (KOCI, Culture-Gap Survey, OCA, Personality Style Instrument). Products are distributed via the company's e-commerce site and the Elevate platform operated by The Myers-Briggs Company.

Kilmann Diagnostics offers a comprehensive portfolio of conflict management assessments and training courses centered on the Thomas-Kilmann Conflict Mode Instrument (TKI). The core product is the TKI assessment, available in three formats: Individual Reports (for self or groups), Two TKIs Per Person (Inside/Outside perspectives), and Team Reports (for established teams). The company provides three-tiered training courses: BASIC Training (2 hours), GROUP Training (3 hours), and ADVANCED Training (8 hours), which can be purchased individually or as bundled collections. The TKI Package combines all three courses with two TKI assessments and the KOCI for certification purposes.
