Answer:
the scope statement; deliverables
Step-by-step explanation:
"Decomposing" a project will ensure an efficient way of accomplishing the project's goal. Before doing this, it is important to know what "the scope statement" is and the "deliverables" (multiple tasks in the production).
"The scope statement" allows one to know what should be included in the decomposition. It also tells when you are going to stop breaking down and what tasks are to be included. Once you know this, it becomes easier to decompose a project with one deliverable at a time. The scope will also be further clarified.
So, this explains the answer.
