Project Management (task management)

Hello community,

I have a question about starting a task. My project structure consists of phases, and within each phase, there are multiple tasks. These tasks are connected sequentially, one after another. However, a user can start the project by working on Task 2 before Task 1.

Is it possible to prevent this? For example, can we restrict Task 2 from starting until Task 1 reaches a certain level of completion?

Thank you in advance. 

Best regards,
Andrey Piskunov
