The best course of action in this scenario would involve a few key steps to ensure all team members are comfortable and capable of participating in the video conference call. Here’s a recommended approach:

1. Assess the Concerns: Reach out to the team members who expressed concerns to understand the specific issues they have with the technology. This could include problems with software, hardware, internet connectivity, or unfamiliarity with the tools.
2. Provide Training and Support:
   • Tutorials and Guides: Share step-by-step guides, video tutorials, and documentation on how to use the video conferencing software. Many platforms have their own help centers with resources for users.
   • One-on-One Assistance: Offer to provide individual support sessions for team members who need extra help. This could be done by the project manager or a designated tech-savvy team member.
   • Test Runs: Schedule a few test runs or practice sessions where team members can join a call to familiarize themselves with the interface, test their equipment, and troubleshoot any issues in a low-pressure setting.
3. Ensure Accessibility:
   • Alternative Options: Ensure the conferencing software is accessible from various devices (laptops, tablets, smartphones) and provide instructions for each.
   • Dial-In Options: If the platform allows, provide a dial-in option for team members who may have limited internet access or prefer to join via phone.
4. Create a Backup Plan:
   • Alternative Communication Channels: Plan for an alternative way to communicate in case some members cannot join the video call. This could include using a conference call line, instant messaging, or email.
5. Document the Meeting:
   • Recording and Minutes: Ensure the meeting is recorded (with permission) and meeting minutes are taken. Share these with the team afterward so those who had difficulties joining can stay informed.
6. Continuous Improvement:
   • Feedback Loop: After the meeting, gather feedback from the team about their experience with the technology and the meeting itself. Use this feedback to improve future meetings and provide additional support where needed.
