Course overview

The objectives of this module are to equip students with knowledge and skills to structure a troubleshooting process in complex IT systems with the aim to detect and eliminate the cause of specific problems.

Students learn:
• Determine a baseline of a functional IT system
• Detect a problem in a complex IT system
• Properly define and differentiate symptoms and causes of problems in a complex IT system
• To eliminate the cause of a problem in a complex IT system
• To propose and implement a modification that improves the resiliency of a complex IT system

This module is important for students because it teaches students how to think critically in the context of complex IT systems. The modue requires students implement a structured thought process, and use in-depth knowledge of the technologies to efficiently detect and eliminate causes of problems in complex IT systems. These skills are crucial for System engineers.

Minimal learning outcomes

  • Determine a base-line of the normal functioning of the IT system
  • Detect a problem in the functioning of the IT system with regards to the base-line
  • Define the problem with regards to the impact on the functioning of the IT system
  • Eliminate the cause of the problem or implement a workaround
  • Propose a modification of the IT system to prevent the recurrence of the same or a similar problem
  • Implement the necessary modifications to the IT system to prevent the occurrence of the same or similar problems in the future

Preferred learning outcomes

  • Compare base-line functioning with total capacities of an IT system
  • Recognize abnormal behavior of an IT system with regards to the base-line
  • Define how the problem will affect the IT system
  • Plan and implement the process of elimination of the cause of the problem
  • Justify the modification of the IT system in the context of preventing future similar problems
  • Plan for the implementation of a necessary modification to the IT system to prevent the occurrence of the same or similar problems in the future
