A "maker's schedule" is characterized by large, uninterrupted blocks of time. This type of schedule is essential for programmers, artists, musicians, and others who need to immerse themselves deeply in a task.

The more of the task they can keep in their head at any one time, the easier it is for them to understand what's going on and make changes. Interruptions, even small ones, can disrupt this state and significantly reduce productivity.

On the other hand, a "manager's schedule" is typically broken up into smaller increments of time, often filled with meetings. This type of schedule works for tasks that can be done in short bursts, like answering emails or administrative tasks.

However, applying a manager's schedule to a maker's work can be detrimental, as it doesn't allow for the deep focus required. Even a single meeting can disrupt a maker's entire day because it breaks up those large blocks of time that are so essential to their productivity.

Most companies are set up around a manager's schedule, which is not conducive to building things. In a startup environment, it's crucial to understand these differences and create a schedule that respects both the makers' and managers' needs. This might involve designating certain days for meetings and leaving other days completely open for uninterrupted work.
