Blocking schedules helps ensure that everyone on your team has enough time to complete their work while also having some free time to recharge. Here are some other benefits:
It helps increase productivity by allowing people to focus on one thing at a time without being interrupted by email or meetings
Reduces confusion about when someone will be available for a conversation or what project they're working on at any given moment
It keeps everyone on the team happy because they know when they'll get some down time and when they'll be busy working on something specific
Allows you to track how much time people are spending on different projects so you can make sure you are allocating resources appropriately across the organization
