[Year 12 SofDev] Software development key knowledge

[Christophersen, Paula P]

Dear colleagues

It's a tricky business writing study designs, and history tells us that paticularly in the first year of a new study design, the intent of some new words is open to interpretation. We are fortunate to have this forum in which we can challenge and discuss the nuances and intent of these words so that we are all on the same page.

Regards
Paula

Hi Paula.  Thanks for the clarification of the KK.  It's good to know what
we should be teaching.

I hope I never insinuated that the Study Design panel deliberately set out
to obfuscate matters; it's just that sometimes the *intent* of the design
can be hard to determine.

As always, many thanks for your ongoing support for us.

Regards
Mark
