Oracle Now Has Two Leaders, But Can These Arrangements Work?

Opinions expressed by Entrepreneur contributors are their own.

, the CEO of , is stepping down. His replacements are a pair of co-CEOs, company insiders and Safra Catz.

While unusual, this arrangement isn't unheard of. It happens frequently in . When two friends start a company, in many cases, deciding who should be in charge is challenging. Neither friend feels empowered to take the lead. After all, they are doing this together. They are equals. It just makes sense.

In our experience, co-CEO arrangements or 50/50 partnerships can work, but they are fraught with danger.

One obvious problem is that if the joint leaders cannot agree on a way forward, the stalls. This happened with Premier Pet Products, a pet-supply manufacturer. Sharon Madere, a visionary entrepreneur, started the business in her guest bedroom. Madere developed a product called the Gentle Leader -- a bridle for dogs that allowed the owner to control the animal without hurting it. On the strength of this product, the business grew into the tens of millions in revenue.

Madere then decided to acquire a related business that made coats for dogs, which was owned by Chuck Mann. In merging their businesses, Madere and Mann became equal partners. Things went along fine for a while. Eventually, differences began to surface. The partners had different visions for the company.

The impasse on vision led to conflict on smaller issues. Unfortunately, as 50/50 partners, there was no way to break the deadlock. Premier Pet Products literally ground to a halt. In the end, Madere and Mann concluded that the best course of action was to sell the business.

On the other hand, we have seen businesses flourish with co-leaders. When was spun off from Signet Bank in February 1995, Rich Fairbank and Nigel Morris headed it. Fairbank and Morris divided the titles. Fairbank was the chair of the board and CEO. Morris was president and COO. When employees were present, the pair was most often seated side by side at the head of the table. They ran Capital One together and it thrived.

Clearly, some co-CEO arrangements and 50/50 partnerships work well. Others fail. If you enter into such a relationship, the three tips below will help ensure that your business will be among those that flourish.

1. Establish a clear division of responsibilities. Our own consulting business, Whitestone Partners, is a 50/50 partnership. We both use the title principal. We are equals. For us, dividing the responsibilities has been a key to success. We play to our strengths.

For example, when working with clients, Doug handles the strategy, operations and finance. Polly focuses on human resources and people management. We divide administrative duties as well. Doug does the accounting. Polly manages the employees. However, as a married couple, if we can't make a decision for our business, we have bigger problems.

2. Each employee should report to only one person. We've seen businesses try to have employees report to both co-CEOs. Invariably, employees get caught between a rock and a hard place. When the leaders give different directions, what does the employee do? When the co-CEOs want the same scarce resource, to which does the employee give it? Don't put employees in this untenable situation.

3. Have a tie breaker. Premier Pet Products became deadlocked, in large part, because there was no mechanism to adjudicate disputes between the co-owners. Conversely, when Fairbank and Morris reached an impasse regarding the strategic direction of the company, the board of directors made the call.

Alternatively, a might divide ownership between partners on a 49/49 basis, awarding the remaining 2 percent to a trusted advisor who would cast the tiebreaking vote when necessary. However you do it, make sure that there is a clear mechanism for resolving disputes.

Co-CEO arrangements and 50/50 partnerships can work, but there are dangers. The tips above will help you, and the new leaders of Oracle, navigate safely around the potholes and bumps in the road.
