If you really want to go into management type position(such as project manager or technical specialists), I would definity do an MBA since you have to be very business focused for this type of job. These type of people are the ones that have to find and maintain customer relationships so a combination of both soft skills and business fundamentals is required for this type of job. People with an MBA has a competitive advantage since they have an insight into complex buisness ideas as well as a background degree with engineering.

Since this topic is more related to marketing, at any types of these positions, it is important to satisfy and build a relationship with your customer. They have to interface with the customer regularly and ensure that they continually aim to improve and exceed the expectations of the customer. 

If possible and it does not delay graduation, I believe getting a minor in business or marketing is beneficial. This minor will expose you to topics and skills needed in a biomedical engineering career, such as customer satisfaction, cost minimization, risks, etc. Having these skills and being able to talk about them during an interview may help when trying to get a job right out of college. However, I believe getting an MBA is probably the most valuable option. Not only will it provide a more in-depth education on business administration, but it will often be partially paid for by the company you are working at. Getting an MBA will open many more potential opportunities, whether it be in a traditional business role, management role, or leadership role.

I do not believe a business minor/major is too useful for an aspiring engineering major. This is because my belief is that an undergraduate education only prepares someone for the immediate next steps, which would either be graduate school or an entry-level job. For graduate school, most MBA programs do not expressly prefer people who completed a business program. For entry-level jobs, most primarily look for people who can perform a job in their primary field of interest. Moreover, in engineering, for people without MBA's, regardless of undergraduate experience, most people do not get into management-geared roles until they have years of experience. This is not to say that all minors are inherently useless, as many often align with students' immediate career goals and help them with their plans. However, business minors may be too far out of reach for such goals. For people who want to focus on a specific business-related career right out of school, and Accounting, Finance, or Marketing major/minor may be more relevant. Everyone else looking to get a quicker foot into management should consider MBA programs rather than undergraduate business classes. MBA programs are more aligned with the needs of industry than are undergraduate course plans. 

I believe a business minor, major, or certification can complement your BME education and enhance your career prospects, especially if you're interested in roles that require a combination of technical and business skills. It can provide a competitive edge and help you stand out in the job market. I know a couple of my friends ended up doing an MBA after graduation because they didn’t know the advantages of having some business experience while completing their undergraduate degree.

I would like to add to atk27@njit.edu response stating that although not required for a management position, it definitely does not hurt to have an MBA or some business background to show that one isn't narrowly focused on one specific topic and that you are even more qualified to take a leading role in a company. I would also argue if someone is looking to create their own medical device company or wants to get involved with a start up, having an entrepreneurship or marketing background would go great for promoting the company's product. Additionally, if you are a part of a company working with suppliers who may be making certain components for a medical device that you work on, not only are they selling themselves and their abilities to you, but it also would not hurt to know the nuances of financial literacy and determine if this is an business relationship of convenience or an actual benefit to your company.
