It's important to weigh up the learning and development time for creating resources versus the outcome.  There's little point in slaving away learning a piece of technology for something you're only ever going to use once.

When developing something, you should always consider re-use.  That's often the big advantage ICT resources have over paper-based; they can be used repeatedly without needing replacement.  (Okay, that is until your computer is upgraded and no longer runs the software!)

Ask yourself a few questions before beginning:

• Will others in your department find it useful?  Or even those in other schools?  (A really good idea is worth sharing!)
• Will it be easy to adapt for other groups, other topics, other difficulty levels?
• Has someone already created something similar that you can adapt?
