In this newly revised and expanded edition, written as a business fable, we meet Debbie Brewster, a new leader. A year ago, she was on top of the world. Today, she is holding on for dear life and might lose her job as her team is not performing well.
She decides to apply to join her company’s new mentoring program. She is accepted into the program and to her shock, she finds out that her mentor will be Jeff Brown, the company’s President and CEO.
Debbie asks Jeff to teach her what the secret of great leadership is. They meet monthly over the next year. Jeff tells her that the secret is, great leaders SERVE. He teaches her five essential ways in which every great leader serves, which he calls the fundamentals. He does this by teaching Debbie the secret of great leaders using the acronym SERVE. Jeff tells Debbie that a key question she must continuously ask herself is, “Am I a self-serving leader or a serving leader?”
At the end of each meeting, Jeff gives Debbie some “homework” that she works on before the next meeting. Slowly, as she applies what she is learning, we see the performance of her team improve as she becomes a better leader. Her team also had a new energy and enthusiasm that truly amazes her. Debbie learns that leading at a higher level includes focusing on both results and relationships. Debbie’s team worked to ascend from “Worst to First” and create raving fans of both their salespeople and their customers.
As I re-read this book, I realized that Debbie’s transformation as a leader matched mine as I embraced that fundamentals of servant leadership. I highly recommend this book. With the Facilitator’s Guide, Study and Discussion Questions and Self-Assessment, it is a book that can be read individually or with a group.
Below are 20 helpful quotes about leadership from the book:
• Everything rises and falls on leadership.
• True leadership has nothing to do with one’s position in the organization.
• A person can serve without leading, but a leader can’t lead well without serving.
• Leadership is about taking people from one place to another.
• Values are a big deal. They are the cornerstones of the culture the leader is trying to create.
• Values are the beliefs that drive our behavior.
• Seeing the future is one leadership responsibility that cannot be delegated. It can be shared, but it’s the leader’s job to make time today to ensure that there is a tomorrow.
• Getting the right people in the right jobs is the first part of Engaging Others.
• The best leaders invest in the development of their people.
• Helping people leverage their strengths is one of the most rewarding parts of the leader’s role.
• If you stop learning, you stop leading.
• We have a stewardship responsibility to maximize our God-given talents. We can only do that as we continuously learn and grow.
• Profits and financial strength are the applause we get for a job well done.
• People don’t care how much you know, until they know how much you care.
• A great leader doesn’t throw people under the bus when there’s a mistake, but they’re eager to give them the spotlight when things go well.
• The best leaders cultivate the ability to think about others first.
• Debbie had learned how great leaders make time to get to know people.
• Leaders learn from the past, but we don’t live there. Leaders are the architects of the future.
• Role models can be a source of inspiration. They demonstrate what is possible and motivate us to serve better.
• Leading at a higher level includes focusing on both results and relationships.

This edition practices what the book preaches to "reinvent continuously." There are slight updates to the last element in the framework. I found little nuggets of wisdom sprinkled throughout the book, such as Assess what happened; Affirm what is working; Adjust as needed. For leaders of non-profit organizations, especially churches, the SERVE framework is a helpful reminder of their fundamental reason for being. It is rare that for profit companies embody serving others without mentioning how it helps the bottom line. I found no such mention of that in this book. Instead we serve because it is an expression of our character as leaders. That message never goes out of style.

This is an excellent resource for new leaders who need fundamental principles. It is also a VERY good reminder for seasoned leaders that need a Vince Lombardi moment, "Gentlemen, this is a football."

I plan to give this to my leadership team so we can grow together as leaders.
