Covidien’s Vice President for Integration, Bill Burke, on integration planning

As plans move forward for the acquisition of Covidien by Medtronic, one of the keys to the success of the future organization will be a smooth integration of both companies. Bill Burke, most recently the Chief Financial Officer for Covidien Europe, is now Covidien’s Vice President, Integration. As head of planning and implementation he will oversee the teams that have been formed to work on various aspects of the integration planning.

Q&A with Bill Burke, Covidien’s Vice President of Integration

What are the goals of integration planning?

We want to ensure a smooth transition upon the closing of the acquisition of Covidien by Medtronic. While the closing is not expected until the end of this year or the beginning of next, we are going to do everything we can to make that transition as seamless as possible. It’s critical that we do so in a way that enables us to maintain our business momentum. That’s our top priority. It is also important that we put ourselves in a position to meet our growth and cost targets. Another key goal is to accelerate our journey toward becoming a fully integrated healthcare product and services company, so that together, Covidien and Medtronic will be able to offer a much broader portfolio of products and services. To accomplish that goal, both companies must be on the same page throughout the integration process, which is why we are working collaboratively with our counterparts at Medtronic.

What is your role with regard to integration planning?

I see my role as being a conduit for delivering value from the combination of our two companies, which means identifying opportunities for growth and for efficiencies from the combination of our businesses.

There are a number of integration planning teams. What are their responsibilities?

We have a core team as part of our integration management office. We also have functional integration planning teams and value driver teams. While they all have different areas of responsibility, collectively their charge is to come up with ideas and plans that support our integration planning goals and then execute those plans. All of this is designed to prepare us not only for day-one of the future organization, but for the days, weeks and months that follow so that we can hit the ground running and sustain our business performance.

What are some of the tasks and work streams that the teams will focus on?

There are several, but here are a few of the most significant. One is master planning – maintaining governance of the integration process and putting various operating mechanisms in place to help us get to our goals. A second is value-capture – making sure that our functional work streams achieve the savings targets that we need to achieve. A third involves the culture of our new joint entity. We need to understand the cultural similarities as well as the differences between Covidien and Medtronic and shape what the new culture will become. And, there’s a team responsible for creating and implementing a comprehensive communications plan so that you and your colleagues will stay informed about what is happening with regard to our integration planning efforts. Beyond the functional tasks, we have teams looking at some of the big picture issues and decisions. For example, how might our two companies do things differently to accelerate growth? Should certain product and service portfolios be handled by us or by Medtronic or both? What’s the best way to go to market? How do we approach our providers and hospitals as this new business entity? We have very capable people working on developing the answers to those questions.

What are the immediate next steps? What will we see happening?

We are still in the preparation stage. Our U.S. integration team leaders have just completed a “boot camp” – a comprehensive training session. We’re preparing a similar session for team leaders who are outside the U.S. We’re in the process of establishing and finalizing cost and synergy savings targets. We’re currently developing the communications plan I mentioned earlier. In short, a lot of prep work is happening right now.

What do you want our employees to keep top-of-mind about the integration?

I would ask everyone to remember that that we are only in the planning process at this point in time. We must continue to run our companies independently and deliver on our current commitments to our customers. That shouldn’t stop while we plan for integration to take place.
