A real-time survey is a tool that allows the project manager to collect feedback from the project team members in an interactive and timely manner. A real-time survey can measure the level of engagement, satisfaction, motivation, and performance of the team members, as well as identify any issues, challenges, or opportunities for improvement. A real-time survey can also increase the participation and collaboration of the team members, as they can see the results and comments of their peers instantly. A real-time survey is more effective than a meeting chat, an email, or a whiteboard, as it can reach a larger and more diverse audience, provide more structured and quantitative data, and avoid distractions and interruptions.
