There is well-known research that shows people’s efforts quickly diminish as team size increases and food truck vendors should use this information to keep your mobile food business efficient.
The primary reason for this is because team members reduce their input when they feel less responsible for the output. Use the smallest team possible to meet the goals you set for your food truck’s daily sales. This may mean including slightly fewer members than the task at hand requires. If reducing the size of your current team is not an option, consider dividing up complex tasks into manageable bits, where every member of the team is accountable for one part of it. Or you can create a sense of urgency about the jobs in the truck so everyone’s invested. If you see staff members not doing their part despite your efforts, be transparent about everyone’s performance so the slackers cannot hide.
