To use dot-voting to prioritize tasks in a team workshop, you need to follow some basic steps. First, you need to define the goal and scope of the voting process, and communicate them clearly to the participants. For example, you might want to vote on the most urgent, impactful, or innovative tasks or options, or on the ones that align best with your vision, values, or strategy. Second, you need to generate and display the tasks or options that you want to vote on, and make sure that they are clear, concise, and consistent. You can use brainstorming, affinity mapping, or other methods to create and organize them. Third, you need to assign and distribute the dots to the participants, and explain the rules and criteria of the voting process. For example, you might want to limit the number of dots per task or option, or allow multiple votes on the same one. Fourth, you need to conduct and monitor the voting process, and give the participants enough time and space to place their dots. You can also encourage them to discuss and justify their choices with each other, or to ask questions if they are unsure or confused. Fifth, you need to analyze and present the results of the voting process, and identify the most popular, controversial, or surprising tasks or options. You can also use the results to plan, prioritize, or execute your next steps, or to generate further feedback or input.
