This is an exercise to have you experience the approach (as best we can online in zoom). You are not bound in any way by the results of the CRC work. Your system structure can, and most likely will, evolve and change as the work progresses.
Put your CRC cards online in your website as a milestone when you are done with the design exercise. You can edit them into a document, or take camera pics of the cards and post those. No need to be pretty, just show what came out of the team discussion(s).
As noted in class, one of the advantages to CRC cards is hands-on face-to-face collaborative work. This advantage will be hindered in our zoom environment, so you will have to figure a way to get the effect of working together on one artifact as best you can.
You might try one person keeping the cards... writing on them... and using a web cam to show the cards to the others as the work progresses. Or perhaps all can keep cards with all the cards being the same. This gives the ability for one person to try a new arrangement, or add a card, and show the result to the others for discussion.
You might try some shared drawing package... or shared text editing. This (as noted in class) is not as good as real cards being handled, but in our current zoom context it might be as good as anything.
When you are done, put the "cards" in some form on the website AND write a brief paragraph explaining how you went about doing the design work.. how did you make cards and share them and manipulate them... what was your team's solution to working together?
After your CRC exercise is done, you may have some better idea of the major sub-chunks your technical componets will divide into... subsystems defined where before you just thought of a system.
Make sure to keep your architecture diagram updated as your notions of the technical structure of your project evolve and get more complex.
