Lesson 3

Test 3

Question 1: What is the minimum descriptive content of a work package?
• (A) Specification of the goal of the work.
• (B) Prerequisites of the work in terms of tools and material.
• (C) Description of the desired work result and its cost.
• (D) Description of the work in terms of verb and object.

Question 2: What is the lowest level of a WBS?
• (A) Sub-objects
• (B) Work packages
• (C) Project phases
• (D) Work package descriptions

Question 3: Which of the following statements is correct?
1. The WBS shall be free of contradictions.
2. For each WBS we need a PBS.
3. The WBS shall be free of redundancies.
4. The PBS does not contain work packages.
5. The lowest level of a WBS contains only work packages.
6. The PBS shows all the work of the project.
Question 4: Determine the critical path (this is the core part of test 3; take paper, pen, and some time and try).

In order to work on this task you need the network diagram. Here you can download it: Network Diagram of the "Desk Project"

The following table contains estimated effort and duration of each work package of the desk example: effort in working hours (wh), duration in hours (h).

Let us take an example: For the work package "Prepare tools" we have
effort = 2 wh, duration = 8 h,
meaning that we will shift the actual work of preparing the tools, that block of 2 working hours, within a time frame of 8 hours, when ever it fits best.

Then, the critical path is ...
• (A) 1 - 2 - 4 - 5 - 6 - 7 - 13 - 14 - 15.
• (B) 1 - 3 - 4 - 5 - 6 - 7 - 13 - 14 - 15.
• (C) 1 - 2 - 4 - 8 - 9 - 12 - 13 - 14 - 15.
• (D) 1 - 2 - 4 - 5 - 6 - 7 - 11 - 14 - 15.

Question 5: What is the duration of the critical path?
• (A) 38 h
• (B) 40 h
• (C) 42 h
• (D) 44 h

Question 6: What is the total effort of that project, in wh?
• (A) 10 wh
• (B) 14.5 wh
• (C) 38 wh
• (D) 40 wh

Question 7: What helps us to prioritize risks?
• (A) Calculating the probability of each risk.
• (B) Multiplying probability with impact of each risk.
• (C) Calculating the impact of each risk.
• (D) Neither one of the above.
