What do students need to do for AS 91360?

1. Explain why redundancy matters in technological systems (what happens without backup components) 2. Explain why reliability matters in technological systems (why systems need to work consistently) 3. Describe how redundancy was actually applied in a real technological system 4. Describe how reliability was actually addressed in that same system 5. Show you understand the difference between backup parts (redundancy) and consistent performance (reliability)

What mistakes do students typically make in AS 91360?

1. Using generic case studies or templates instead of engaging with your own technological practice or examples you can actually explain 2. Describing what redundancy and reliability are without explaining why they matter or what problems they solve 3. Listing features without connecting them back to the actual design decisions that were made during development

System reliability

Q: What's the difference between Achieved, Merit, and Excellence for AS 91360?

Achieved: You explain both redundancy and reliability in general terms, then describe how they were used in a real system. Merit: You explain why specific redundancy and reliability decisions were made in the development of your chosen system, not just what was done. Excellence: You discuss how redundancy and reliability thinking actually shaped the design choices and ongoing maintenance decisions throughout the system's development.

This standard asks you to explain why systems need backup parts or extra components (redundancy) and how we make sure systems work reliably over time. You need to describe real examples of how redundancy and reliability were actually built into a technological system you've studied or worked on.
