About the author

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.**

[Sedobi Denipl · Rating 5 out of 5]

This book challenged me more than I expected. I went in looking for tactics and came out thinking about adaptability and leverage in a much broader sense. Chevalier makes a strong case that negotiation failures often come from refusing to evolve. That idea hit close to home. I liked how the examples feel grounded in real decision making rather than ideal scenarios. The writing doesn’t talk down to you. It assumes you’re capable of growth but also willing to confront blind spots. I’ve already started applying some of the principles in everyday conversations, and the results feel more controlled and deliberate. This book rewards careful reading.

[Jithendra Jithu · Rating 5 out of 5]

EVOLVE or Be Slaughtered: Negotiation for the 21st Century by Derrick Chevalier is a bold and uncompromising exploration of what negotiation truly looks like in today’s high-pressure, fast-changing world. From the very beginning, the book establishes a sense of urgency, making it clear that outdated approaches are no longer sufficient. Chevalier frames negotiation not as a polite exchange of interests, but as a strategic discipline that demands awareness, adaptability, and decisive action. The tone is direct and confident, reflecting the author’s belief that survival in modern negotiation depends on evolution rather than tradition.

One of the book’s strongest qualities is how it respects classic negotiation theory while refusing to be constrained by it. Chevalier openly acknowledges the groundwork laid by respected figures such as Chester Karrass, William Ury, and Chris Voss, yet he moves beyond their frameworks to address contemporary realities. Negotiation, as presented here, is fluid rather than formulaic. Power shifts quickly, leverage changes without warning, and success depends on reading the environment as much as understanding the other party.

At the core of the book is Chevalier’s continuum-based framework and the CNSUF™ negotiation model, which provide structure without rigidity. These concepts emphasize adaptability, allowing negotiators to respond effectively across a wide range of situations. Whether applied to corporate negotiations, leadership disputes, political dealings, or international relations, the framework scales naturally. This flexibility makes the book relevant to readers from diverse professional backgrounds, not just traditional business negotiators.

The practical nature of the writing further sets this book apart. Chevalier draws heavily on real-world experience, giving the strategies a sense of authenticity and weight. The advice is not softened or idealized; instead, it reflects the realities of high-stakes negotiation where mistakes carry real consequences. This makes the book especially valuable for experienced professionals who want to refine their instincts and sharpen their strategic thinking rather than revisit basic principles.

Overall, EVOLVE or Be Slaughtered is less a passive guide and more a strategic challenge to the reader. It pushes negotiators to abandon complacency and rethink how influence, leverage, and communication function in the modern world. Derrick Chevalier delivers a compelling roadmap for those willing to adapt and grow, making this book a powerful and relevant contribution to contemporary negotiation literature.

🤔 My thoughts on this book

I've had the pleasure of meeting and talking with Derrick, and what I am learning from him is nothing short of incredible. The level of precision and attention to detail in negotiation can get you really far if you apply what he teaches in the book.

I was able to successfully apply some of the concepts presented in this book and made the biggest deal of my life (so far). I am still evolving and thus will return to this book as often as possible to implement more concepts or refresh my memory.

It turns out negotiation is more multifaceted than most experts make it appear, meaning there is more than one element to consider when negotiating.

"Why should I read this book❓"

Whether you are negotiating interpersonal issues, multimillion-dollar agreements, politics, international relations, or anything else where negotiation is involved, this book equips you with the skills to master the art of negotiation in the 21st century.

[Calvin · Rating 5 out of 5]

EVOLVE or Be Slaughtered approaches negotiation as a survival skill rather than a polite exchange. Derrick Chevalier makes it clear that the modern world rewards those who can adapt quickly and decisively. The book feels grounded in real experience, not theory meant to sound impressive on paper.

What makes this book compelling is its refusal to oversimplify negotiation. Chevalier presents it as a living process shaped by power, timing, and intent. The CNSUF™️ model offers structure while still allowing flexibility, which makes it practical rather than restrictive.

This is a book best suited for readers who want to think differently. It challenges comfort zones, questions old habits, and encourages strategic growth. Anyone serious about influence and decision-making will find this read worthwhile

[Jerry Wane · Rating 5 out of 5]

I picked up EVOLVE or Be Slaughtered because I negotiate often and felt stuck using the same old approaches. What I didn’t expect was how much this book would challenge my assumptions. Chevalier doesn’t just talk about tactics. He talks about mindset and adaptability. That shift alone made the book worth reading. I liked how the concepts are grounded in real situations rather than theory for theory’s sake. You can feel the experience behind the words. It made me rethink how rigid I had become in my own negotiations. Instead of trying to win, I started focusing on positioning and momentum. That change has already made conversations feel more controlled and less reactive. This is not a quick read. It’s the kind of book you pause, reflect on, and come back to.

[Tejasri · Rating 5 out of 5]

This book reads like a strategic briefing rather than a traditional negotiation manual. Chevalier writes with authority and clarity, drawing from years of real-world experience. There is a seriousness to the message that demands attention.

The continuum-based approach stands out by encouraging flexibility instead of rigid steps. Negotiation is presented as something that must respond to changing circumstances, not follow a fixed formula.

For readers who want a modern perspective on influence and communication, this book delivers strong insights. It is thoughtful, challenging, and grounded in reality.

[Sergio Harish · Rating 5 out of 5]

What stood out to me is how practical this book feels without being simplistic. Chevalier clearly understands that negotiation today isn’t just about deals. It’s about people, pressure, and constantly shifting conditions. I appreciated how the framework adapts depending on context rather than forcing one method into every situation. Reading this made me realize how often I default to comfort instead of strategy. The emphasis on evolution felt very real to me. If you negotiate in business, leadership, or even personal situations, this book gives you a sharper lens. It doesn’t promise shortcuts. It demands awareness. That honesty made me trust the material more.

[Barleen Reviewer · Rating 5 out of 5]

I’ve read a lot of negotiation books, and many of them recycle the same ideas. This one feels different. EVOLVE or Be Slaughtered isn’t trying to replace the classics. It builds on them and pushes forward. What I liked most is the idea that negotiation is a living process, not a fixed skill set. That resonated with my experience in high pressure environments where conditions change quickly. The book helped me recognize patterns I had been missing. It also made me more intentional about preparation instead of relying on instinct alone. This isn’t about memorizing moves. It’s about learning how to think when the ground shifts under you.

[Geowgi Trek · Rating 5 out of 5]

What I appreciated most about EVOLVE or Be Slaughtered is that it respects complexity. It doesn’t pretend negotiation is clean or predictable. Instead, it shows how to navigate uncertainty without freezing or forcing outcomes. The continuum based approach made a lot of sense to me, especially when dealing with mixed power dynamics. The book helped me understand why some negotiations stalled even when I thought I was prepared. It’s not about being aggressive or passive. It’s about positioning yourself intelligently as conditions change. That shift in thinking alone made this a valuable read for me.

[Carry Re · Rating 5 out of 5]

What I liked about EVOLVE or Be Slaughtered is that it doesn’t assume negotiation happens in clean boardrooms with clear rules. It recognizes how messy real negotiations are. Power shifts. Emotions interfere. Information is incomplete. Chevalier doesn’t fight that reality. He works with it. The continuum based thinking helped me understand why some conversations stalled even when I thought I had leverage. Instead of forcing outcomes, the book teaches you how to move with the situation while staying intentional. That approach felt more realistic than rigid frameworks I’ve seen elsewhere. It made me more patient and more observant in how I negotiate.

[Telado · Rating 5 out of 5]

This book made me rethink how often I rely on familiar tactics just because they worked before. Chevalier’s emphasis on evolution feels earned, not theoretical. The writing reflects someone who understands how negotiation environments change quickly and unpredictably. I appreciated how the ideas scale across situations, from everyday conversations to higher stakes decisions. It’s not about overpowering the other side. It’s about reading momentum and adjusting intelligently. After reading this, I caught myself preparing differently, focusing less on scripts and more on flexibility. That shift alone made this book worthwhile.

[Katyy R · Rating 5 out of 5]

What stood out to me is how this book treats negotiation as a living process rather than a single moment. Chevalier repeatedly brings the focus back to awareness, timing, and adaptability. That perspective helped me understand why some negotiations fail even when both sides seem reasonable. The book doesn’t push a one size approach. It encourages you to recognize where you are on the continuum and act accordingly. I found that concept surprisingly useful. It made my thinking clearer and less reactive. This book rewards readers who are willing to question their habits rather than just collect tactics.

[Ranjh Sam · Rating 5 out of 5]

I went into this book expecting strategies. What I got was a deeper understanding of negotiation dynamics. Chevalier doesn’t frame negotiation as confrontation. He frames it as movement. That shift in language and thinking made a real difference for me. The book helped me recognize moments when pushing harder was actually weakening my position. It also reinforced the importance of preparation that goes beyond numbers and terms. Context matters. Timing matters. Adaptability matters. This book doesn’t give you shortcuts, but it gives you something better. Awareness that lasts beyond a single deal.

[Rajamani · Rating 5 out of 5]

EVOLVE or Be Slaughtered pushes readers to rethink how they approach negotiation in everyday and professional settings. The book does not sugarcoat its message and instead highlights the risks of relying on outdated strategies.

[Marique · Rating 5 out of 5]

This book feels like it was written by someone who has actually been in the room when stakes are high. The insights don’t feel theoretical. They feel earned. I found myself nodding often, especially during sections that deal with pressure and timing. The emphasis on evolution reminded me that negotiation is not static. What worked five years ago may not work today. That reality is easy to ignore until it costs you. This book doesn’t offer comfort. It offers clarity. If you’re willing to adjust how you approach negotiation, there’s a lot here to work with.

[Scarlett · Rating 5 out of 5]

Reading this made me realize how often I approach negotiation with outdated habits. Chevalier does a good job showing why adaptability matters more now than ever. I liked that the book doesn’t push a single personality type. It works whether you’re analytical, intuitive, or somewhere in between. The framework encourages awareness over ego, which I found refreshing. I’ve already changed how I prepare for conversations, especially in identifying leverage and flexibility early on. This book feels like a long term investment rather than a one time read.

[Dan Serg · Rating 5 out of 5]

What separates this book from others in the genre is its focus on evolution rather than control. Chevalier doesn’t promise dominance. He emphasizes awareness and movement. That felt honest. Negotiation rarely goes according to plan, and this book acknowledges that reality instead of fighting it. I appreciated how the ideas apply across industries without feeling vague. The principles scale naturally, whether the stakes are small or significant. It made me more conscious of how quickly conditions can change and how important it is to adapt without losing direction.

[Sherry Sam · Rating 5 out of 5]

This book helped me slow down my thinking during negotiations. Instead of reacting, I started observing patterns and shifts more clearly. Chevalier’s approach feels calm and strategic rather than aggressive. That balance made the concepts easier to apply in real conversations. I also liked how the book frames negotiation as an ongoing process rather than a single event. That perspective alone changed how I follow up and reassess outcomes. This is a book for people who want to improve how they think, not just what they say.
