In my experience, I've used weekly in person meetings in order to make actual progress in a project I'm working and discuss with coworkers. Then I use Slack and some of my free time in order to conduct more research and discuss the next plan of action in the next in person meeting. Other than slack, I've used emails to communicate the next order of business.

In medical device projects, where precision and clarity are paramount, combining formal and informal communication methods often proves most effective. A strategic mix of these methods can address the fast-paced and intricate demands of such projects. For instance, structured weekly team meetings are essential for discussing complex issues like regulatory requirements or design changes, where misunderstandings can lead to significant setbacks. These meetings provide a forum for all team members to voice concerns, share updates, and align on the project's direction and priorities. They ensure everyone is on the same page and can make informed decisions together.

Between these formal meetings, continuous informal communication through tools like instant messaging apps (e.g., Slack) or internal wikis helps maintain project momentum and fosters a collaborative team environment. For example, engineers working on a new device can use Slack to quickly share updates or ask for immediate feedback without waiting for the next scheduled meeting. This rapid exchange of information can be crucial when dealing with time-sensitive issues like troubleshooting prototype problems or finalizing a submission to a regulatory body. By blending structured meetings with flexible, on-the-go communication, teams can navigate the complexities of medical device projects more effectively, ensuring both thoroughness and efficiency.

Maintaining clear communication among team members in a development project is essential, yet choosing the best communication method can be challenging due to differing personalities and communication styles. Effective communication directly impacts project management success. Several factors can hinder effective communication, including the project's nature, the organization's structure, and the challenges faced during development. To promote effective communication, project managers must understand the communication process. One key factor is selecting the right medium for conveying messages. For example, written communication, such as logs or emails, may be preferable over face-to-face discussions when time constraints and management factors make in-person meetings impractical. Additionally, it is crucial to deliver messages thoughtfully, as the wording can significantly influence communication outcomes. For instance, when negative schedule performance arises, it is important to provide constructive feedback that encourages growth both professionally and personally. Incorporating small, daily communication habits can also help ensure that messages and results do not get lost. Finally, identifying the key W questions (Why, what, when, where, who) and the H question (how) can further enhance communication clarity. Overall, fostering a strong organizational culture and structure is vital for effective communication within the organization and with stakeholders.

The most effective form of communication in medical device projects is a combination of structured and transparent communication channels. Clear documentation through written reports and meeting minutes ensures traceability, which is critical for regulatory compliance. Face-to-face or virtual meetings promote real-time collaboration, especially during design reviews or risk assessments. Cross-functional team meetings help align engineering, quality, regulatory, and clinical teams on project goals. Using project management tools like dashboards enhances visibility and helps track progress, deadlines, and issues. Email remains essential for formal communications, especially with external stakeholders and regulatory bodies. However, overreliance on email can lead to miscommunication or delays if not supplemented with direct discussions. Instant messaging platforms like Slack or Teams help facilitate quick updates and decision-making in fast-paced environments. Ultimately, the most effective communication strategy blends timely, accurate, and audience-appropriate methods to ensure alignment and compliance throughout the project lifecycle.

Based on your experience, I have only seen and done three forms of communication: Microsoft Teams messages, email, and verbal dialogue. All three are extremely effective when used correctly and with the right people. I do not believe there are any other forms of communication. Documentation and record keeping is a form of data storing, not communication. Team members, project managers, and upper management can communicate in the three aforementioned ways. Different people prefer different forms of communication. Often times, people prefer Teams messages, as it is a quick way to get the message across. Others prefer email, as it is more "official" and may be better for sending documents. However, some may people may require in person communication if messages and emails go unread or responded to. The engineer needs wisdom and the ability to "read" people in order to effectively communicate. 

While I don’t have industry experience yet, I’ve worked in team settings like capstone projects where communication was just as critical to keeping things on track. What worked best for us was a combination of weekly team meetings and informal messaging (we used texts and shared Google Docs). The scheduled meetings helped us stay aligned on tasks and deadlines, especially when we were juggling class schedules and lab availability. In between meetings, having a quick way to check in, ask questions, or give updates made sure things didn’t stall out. I’ve seen how even a small miscommunication can slow things down, so having both structured and flexible channels really helped us stay efficient. I imagine the same principles scale up in industry, especially when timelines and regulatory details become even more intense

My older internship used Microsoft teams. My current job uses slack. I like slack more as I find it has more flexibility in how it is used. For school projects, I've learned that the most useful platform will be whatever you team is most experienced in. Most of the time, people tend to rather phone group chats. I also have had a lot of luck with discord, it's screen sharing feature is helpful to focus on project parts and show details to eachother. 

In my opinion, I believe that face to face meetings regarding the project no matter the length are always the most effective ways of getting something across in team projects. In all of the projects that I have been in, academic or otherwise, communication was always the main factor on whether the project succeeded or not. For medical device projects especially consistent group communication is imperative for establishing focus, scheduling and most importantly trust between group members. Face to face communication is not always available for people to do consistently which can lead to some aspects of discussion to become lost in translation. I believe an effective counter measure for this would be video calls between the members to get going a full length conversation on the state of the project and the direction that it should be heading. Just sending text messages or emails to people as directives or instructions to go forward is not going to bring about discussion between the members which should honestly be the entire point of communication. Medical device projects deserve focus and structure, and there is no better way of getting that structure or focus then by starting a conversation. 

If I had to choose one most effective form of communication in medical device projects, I would strongly argue that formal, documented communication is the most critical. In a regulated industry, I believe documentation is not optional but rather foundational. Design reviews, risk assessments, meeting minutes and change control records create traceability and accountability. Without clear documentation, decisions can be misinterpreted, requirements can shift unintentionally and compliance risks increase significantly. While informal communication like slack or quick meetings can help with day to day coordination, they should never replace structured documentation. 

Similarly to what others have mentioned, in my job, the go-to is Microsoft Team's messages and Outlook for sending emails and setting up emails. Teams allows for quick communication--messaging and even calls when its urgent. Outlook allows for setting up meetings and sending emails where you can cc several team members to communicate with everyone. An important note to consider is that though you may have these tools for helping aide communication, they still need to be used effectively to establish efficient communication. 

By that I mean that projects often have recurring meetings to cover certain topics. And ensure that things are therefore not missed. The PM needs to identify items that need to be consistently tracked and pushed forward to ensure tasks still meet project deadlines.
