1. Clearly outline your vision statement and drivers

When there is no clear importance or impact associated with the task, research shows that teams that understand how their work fits in to the bigger picture are more effective (they’re more creative and resilient, to boot). 

At the start of your group project, make obvious to your team:

What this project’s value is (the vision)

Why this project makes sense for your team and your organization (the drivers)

Ensuring alignment around those pieces empowers team members to see the impact of their work, It will ignite motivation and sense of ownership over their assigned tasks / milestones.
