Clinical development of a product or device is a tough, highly regulated process. For a medical device company, the success of an FDA submission depends on having an efficient design and manufacturing process. There are many disparate experts involved in making your product a reality—from initial concept creation to architecture, design, component specification and sourcing, testing, and manufacturing. All those parts, pieces, and experts are what make Systems Engineering so valuable, as we’ll explain below.
Looking to Ensure Success?
Inevitably, problems can quickly arise with so many different “cooks in the kitchen”. It’s not uncommon for various team members to work separately, or for many domain specific experts to not have full visibility and/or understanding into all of the systems. For example, the architect may be highly skilled at what they’re doing, but fail to consider something that the designer would have thought was obvious, and vice versa. The lack of big-picture oversight and project coordination is a major cause of project failure—leading to improper scoping, budget overruns, poor user experience, wasted time and money, failing tests, and more.
Fortunately, there is one crucial team member who can help ensure ultimate project success: the Systems Engineer. In this article, we’ll discuss the role of the Systems Engineer— and help you see why no medical device project should start (or proceed) without one (or several) at the helm.
What Is a Systems Engineer?
A Systems Engineer is a person who deals with the design, development, deployment, and maintenance of systems. You can think of a system as a complex collection of people, technology, and procedures that work together to solve a problem or achieve a goal. A good analogy is the human body, which has seven different systems that all interact with each other. Complex products such as medical devices also have various systems that interact with each other.
The engineering spectrum, or “systems”, for a particular medical device project will touch on everything from electronics hardware to electromechanical and software design, as well as related disciplines like product usability and graphical interface design. Much like a symphony conductor, the Systems Engineer bridges the gap between these and other disciplines to bring clarity and harmony throughout the development lifecycle.
How Systems Engineers Work
Systems Engineers are involved in architecting medical device solutions from the very beginning of a project. They are adept at seeing the big picture, as well as all the intricate details. From this vantage point, they are able to coordinate with all the other experts on the project. Most importantly, however, they help identify the key risks and constraints and determine how to design test protocols and other mitigation response plans. They also need to ensure that all aspects of systems engineering are incorporated into the final product, so it will meet regulatory requirements.
Initially, Systems Engineers “zoom out” and examine everything from a 30,000 foot perspective. Then, they work with the team to put together the main framework, or skeleton, of the project and identify key components the system (i.e., the final product) is going to need in order to operate.
The Systems Engineer’s job is to see everything holistically—both the overall project itself as well as the interplay between the project team members and their specific domain knowledge and expertise. As projects progress, Systems Engineers also “zoom in” on the details of the project. They can go back and forth between the micro and macro views easily. Systems Engineers help ensure that the right parts are in place to prevent errors and ensure product safety and efficacy. They oversee all of the different components that contribute to the end user’s experience of a medical device. They also work on things like software, hardware, usability, interface design and machine learning — all with the ultimate goal of preventing harm to patients.
What’s more, successful systems engineers must be highly organized as well as highly adaptable.
Top Five Tips for Working With a Systems Engineer
Here are five tips on how to work with Systems Engineers to meet and exceed your expectations and requirements for your medical device. These tips are especially crucial if you’re pursuing FDA approval!
1 - Involve a Systems Engineer Early in the Project
The most critical function that a Systems Engineers plays at the beginning of a project is to identify and address the most technically challenging things up front. According to Nectar’s founder and CEO Darren Saravis, “That's the hallmark of a really good Systems Engineer”.
Unfortunately, teams often skip this fundamental step—only to later discover unidentified risks that can cause significant rework or even derail the project.
“We have learned that while many project teams have the right technical expertise (mechanical engineering, software design, etc.), there will inevitably be ‘blind spots’—such as a proven user-centered design experience,” Saravis said. “The Systems Engineer’s job is to have 20/20 vision to help eliminate and overcome any missing elements.”
2 - Design with the End User in Mind
The customer doesn't care how the microprocessor works—or how some other intricate piece of your technology was made. What are they interested in? Whether the final device works flawlessly, as intended, and solves their problems. To be a success, your product absolutely must be designed with the end user in mind.
However, all of those other detailed elements running in the background are vitally important, even if the customer never notices or understands them; the Systems Engineer’s job is to make sure that the end result works properly, incorporates fail safe designs, and does so at a high standard.
3 - Validate Early and Often
Systems Engineers are adept at guiding medical device projects through a validation cycle to confirm that the device meets its specifications set forth in the requirements. At Nectar, our Systems Engineers follow a rigorous process to validate the feasibility and viability of products—and ultimately meet ISO 13485 standards. This is not a process to attempt last minute, and it’s also not a one-and-done deal.
Instead, validation processes should happen regularly throughout the process, starting early on and occurring frequently.
4 - Avoid Groupthink
It is common for project teams to tailor their solutions around prevalent or dominant opinions and expertise—such as focusing too heavily on hardware design, software, or other disparate aspects. The Systems Engineer is responsible for aligning all aspects of the project, which alleviates groupthink and balances competing interests and priorities.
5 - Maximize Your Investment
By focusing on identifying and solving the toughest challenges and risks from the very beginning of projects, Systems Engineers help companies optimize their investment. Risk mitigation is all about spending the least amount of money to get the most amount of information, which is a major part of what a Systems Engineer brings to the team.
In addition, Systems Engineers also assess and manage critical parameters—things that are difficult, important, or new during a project. Rather than spending months or years and millions of dollars tackling the “easy” things first and addressing problems later—Systems Engineers guide teams by properly iterating, testing and validating at every step of the way. This agile development approach is proven to produce better results.
Working With Nectar’s Systems Engineers
At Nectar, we want to be your Systems Engineering partner early on in the process. We’ll help you start off the right way—or quickly get you back on track if your project started prematurely or has hit a roadblock.
The certification process for medical devices — such as pacemakers, defibrillators, and ventilators— is extensive and can be quite technical, according to the U.S. Food and Drug Administration. Our job is to make sure you have outstanding Systems Engineering oversight throughout the process, so you can achieve your goals on time, on budget, and with the quality your customers deserve.
Pursuing the Greater Good
We specialize in medical device development, industrial equipment, and connected devices (IoT) development. With an emphasis in medicine, energy, and food, we seek out projects that align with our pursuit of a greater good.
