The foundations and tenets of the Comprehensive Negotiating Strategies (CNS), Negotiation Framework. CNS is the first universal negotiation framework built and designed for the complex issues of the Emerging Integrated Global Economy (EGIE) of the 21st Century. EVOBS describes proprietary principles, tactics and strategies applicable for virtually all types and levels of negotiation from simple buy/sell transactional issues, to complex national and multinational business, political, engineering, sales and procurement challenges.
Derrick Chevalier has never followed a conventional path—and neither do his books.
An author, negotiation strategist, consultant, trainer, mediator, researcher, and creator of the **CNSUF® Comprehensive Negotiating Strategies Universal Framework**, Derrick draws upon an unusually eclectic background spanning business, law, communication, psychology, real estate, mediation, leadership, and military service.
A U.S. Marine Corps veteran, he earned undergraduate degrees from USC in **Political Science/Pre-Law** and **Speech Communication/Theatre Arts**, later earning a master’s degree and completing advanced mediation training through **Harvard Law School**. He is also a licensed California Real Estate Broker and has spent more than 25 years working with individuals, executives, organizations, and professionals across diverse industries.
One of the most formative influences on his work was his longtime association with legendary negotiation authority **Dr. Chester Karrass**, whose mentorship helped shape Derrick’s lifelong study of how people negotiate, influence, decide, compete, cooperate—and sometimes miscalculate.
That journey ultimately led him to develop CNSUF® and to write books that challenge traditional assumptions about negotiation, including ***EVOLVE or Be Slaughtered: Negotiation for the 21st Century***, ***Beyond Negotiating: From Fear to Fearless***, and ***Influence–Rapport–Results***.
Derrick writes for readers who want more than clever tactics. His work explores the deeper architecture of human interaction: **how people think, what drives their decisions, how influence actually works, why negotiations fail, and how we can continually evolve our ability to achieve better outcomes.**
If you believe negotiation reaches far beyond the conference room—and into business, relationships, leadership, politics, conflict, and everyday life—**follow Derrick on Goodreads and join the exploration.**
