Part A – MBSE Foundation [ 40 Marks]
1. Name the key benefits of MBSE in comparison to traditional systems engineering practice. [2]
MBSE is a formalized process that depends on modelling system requirements, designs, analysis, verification and validation activities from beginning to end of a project lifecycle. MBSE primarily uses models to run scenarios and provide “what if” analysis to help determine requirements and further define a system.
2. For the Systems Engineering Design Process, list at least 3 activities within each of the followings:
• requirements analysis [2]
Answer.
• functional analysis [2]
Answer.
• synthesis [2]
Answer.
• system analysis and control [2]
Answer.
3. MBSE model:
• What is a systems model? [1]
Answer.
• What is a viewpoint? [1]
Answer.
• What is a view? [1]
Answer.
• What is a diagram? [1]
Answer.
4. MBSE methodology:
• What is a process? [1]
A process defines what is to be done, without specifying how each task is performed.
• What is a Method? [1]
A method consists of techniques for performing a task, in other works it defines the “how” of each task.
What is a Tool? [1]
A tool is an instrument that when applied to a particular method, can enhavnce the efficiency of the task; provided it is applied by someone. The purpose of a tool should be to facilitate the accomplishment of the “how”.
5. Name the four Pillars in SysML and the SysML diagrams used in each pillar. [4]

7. Name 2 Defense Architecture Frameworks. [2]
Answer.
8. Name 8 viewpoints in DoDAF 2.0. [8]
Answer.
9. Describes key characteristics of a system of Systems. [4]
Answer.
10. (Bonus Question) What are the 5 key aspects of the Systems Engineering Standards Framework? [5]
Answer.
