Project-based work rarely goes as smoothly as planned. Deadlines suddenly come up, the desired quality of work might be elusive, or clients may change their minds. All of this can lead to situations where people do not know what they might be working on one day to the other.
You might think of these constantly changing projects as a catalyst of creativity. In reality, this lack of predictability may be hurting the quality of work.
Predictability benefits both your organization and your staff. If the organization has good insight into whether a project will be profitable and your team has a clear expectation of their workload, everyone can stay aligned around project outcomes and focus on doing their best work within the budget.
