How to succeed in RA and other tips and words of wisdom from Boston Scientific retiree and University of Minnesota professor Mac McKeen.
By Mac McKeen
Recently retired from a 35-year career in medtech, I want to share some of my experiences and “pearls of wisdom” with you as you continue your journey.
I have had the good fortune of spending my entire career with big and small companies in Minnesota making cardiac medical devices. Life-saving device development and approval offers exciting challenges and the chance to work at great OEMs like Medtronic, St. Jude Medical (now Abbott) and Guidant (now Boston Scientific).

Equipped with knowledge of the end-to-end total product life cycle (TPLC) and quality system processes, I joined the regulatory team to work cross functionally, understand the nuances of the process and translate that to the story in submissions. My MBA in contract administration helped me adapt the business process to a highly technical process. The combination of a technical undergraduate degree and an MBA served me well, as I realized my preference was for the business process, not the engineering process.
What is RA? Nothing happens until somebody sells something — and nobody sells medical devices until they are regulatory approved!
Regulatory affairs is one of the few functional areas in a company that is involved from beginning to end of the TPLC. It’s unique in that we get to work directly with most of the other functional areas in the product development process, clinical study and regulatory submission process. Regulatory professionals tell the story of work the team developed to demonstrate and support the product’s safety and performance to meet the intended use and labeling claims.
The 4 Cs for submission success: clear, concise, compelling, and complete
RA is a perfect combination of technical content and business acumen. The ability of the RA professional to understand and apply the technical aspects of the product design and testing and meld this with the technical writing of preparing the submission and telling the story of a product’s development, presenting this information to regulators in a clear, concise, compelling and complete manner is the key to success. RA offers the playbook to the business on how to plan and prepare and win at this process.
Project management and technical writing are fundamental skills that RA professionals need to grow and succeed. Another key is the ability to develop regulatory strategies to address the many challenges of navigating the regulatory process. Effectively communicating these strategies verbally and in writing are essential. To that end I recommend that you take the RAC exam and become RAC certified with RAPS. This is a professional and personal credential that will set you apart from the pack and help fuel your career growth.
The 4 Ps to success: people, process, products and patients
Everything in life is a process. Making medical devices is a process that starts with people using the process to develop products to treat patients.
While the premarket side of RA is more exciting and glamorous, the postmarket role of RA is essential for managing changes to process and products and compliance with regulations and performance of the product (recalls and field actions). I recommend taking on roles and responsibilities in each of these areas.
Post-approval change management is the key difference between medical devices and pharmaceuticals. In the drug industry, they get a product approved and never change the formula.
The device model, on the other hand, is based on launching a product platform — or what I refer to as the “revolution” of the product — and make incremental improvements to expand indications for use and improve performance, which I call the “evolution” of the product as represented in the TPLC model below.

Find your purpose in RA: My definition of quality is: When your customers come back — and your products don’t!
My career in RA guided me to find passion and purpose in the work we do, all related to the patients we serve. RA is a unique role with the opportunity to partner with the quality organization to provide guidance to the team to take the steps necessary to meet the complexities of the regulations around the world, but also to design and manufacture a quality product that fully meets the labeling claims and requirements in the field.
At the risk of overstating the role of RA to the organization, we are a strategic partner and can help build and maintain a high compliance culture at the company. I call that passing the “red face test.” If you can’t explain the approach clearly and completely and you are using a lot of rationalization and leveraging of data, you are putting the process and the product approval at risk — not to mention the patient. The bottom line is that good compliance is good business.
My career ran parallel paths, with simultaneous jobs in industry and education. I invested 25 of those 35 years in educating others about the regulatory process and TPLC to help fill the industry’s talent pipeline. This was well worth the time and effort, providing another outlet for my passion and culminating in the honor of being recognized as a RAPS Fellow in 2020. This was one of my proudest achievements, as it allows me to continue promoting and advancing the RA profession through various committees and board positions.
Thank you for letting me share my experiences with you from my rewarding and fulfilling career. Now it is your opportunity to continue the work we do for patients and achieve your own career dreams.
