The following are a sample of some core values from several companies I’ve either visited or read about — and I like their stated values.  I’ve also included the Four Agreements at the end because I think these are an example of values that help people and teams that work together.

Zappos Family Core Values (Example)
As we grow as a company, it has become more and more important to explicitly define the core values from which we develop our culture, our brand, and our business strategies. These are the ten core values that we live by:
1. Deliver WOW Through Service
2. Embrace and Drive Change
3. Create Fun and A Little Weirdness
4. Be Adventurous, Creative, and Open-Minded
5. Pursue Growth and Learning
6. Build Open and Honest Relationships With Communication
7. Build a Positive Team and Family Spirit
8. Do More With Less
9. Be Passionate and Determined
10. Be Humble

My Body By Vi Challenge (Example)
The Vi-6 Core Values
1. Be Inspired, Be Inspiring
2. Build Trust through collaboration.
3. Be a good teacher and a better student.
4. Think like an entrepreneur, be resourceful.
5. Challenge yourself
6. Seek Simplicity.

EVEREST:  What we care about:
Transparency:  We are open, honest and direct in everything we do. We share ideas, raise concerns and applaud success.
Fail Fast:  We live in an entrepreneurial environment. We take risks. We fail fast. We fail forward. We learn and iterate.
Passion:  We love solving problems. We relentlessly work to improve the lives of our customers.
Meritocracy:  We believe that the best ideas win. Title and resume are not relevant when it comes to finding the best solutions.
Listen:  We listen to our employees. We listen to our customers. We listen to the community. When we listen, we learn.
Treat people well:    We treat everyone with fairness and respect.

The Four Agreements are:
1. Be Impeccable with your Word: Speak with integrity. Say only what you mean. Avoid using the Word to speak against yourself or to gossip about others. Use the power of your Word in the direction of truth and love.
2. Don’t Take Anything Personally
Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won’t be the victim of needless suffering.
3. Don’t Make Assumptions
Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness and drama. With just this one agreement, you can completely transform your life.
4. Always Do Your Best
Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse, and regret.
One comment I liked was “You are the CEO of your job” — meaning that you are in charge of making your job work and managing what is needed to make it work best.
One other good thing is “What would you do, what decisions would you make, if you knew that you would succeed and not fail?”
