Question

The process of splitting a deliverable into smaller more manageable parts is known as : 1. scope definition 2. decomposition 3. activity definition 4. activity list

Answer 1

The answer is 2) decomposition.

The process of splitting a deliverable into smaller more manageable parts is known as decomposition. The splitting takes place till the deliverables and work are defined at the work package level. However, it must be kept in mind that too much of decomposition can cause more work to be done with no or very less value for the time spent.

Answer 2

The correct answer is 2: decomposition.

Decomposition in project management is a technique for dividing and sub dividing project scope into smaller manageable parts. 
This is done by dividing work structure beginning from the highest level.
Then all the work packages and work break down structures are given a unique code.   

Therefore, optimum level of decomposition should be done in order to improve work efficiency.
