If anyone is curious, I did end up moving forward with this idea today at our creative department's Show & Tell (a quarterly meeting where our separate creative teams show everyone what they've been working on). I started with just under 5 minutes of new features and techniques they probably weren't aware of, then for the refresher portion, I did a pop quiz and the first to answer correctly won a gift card to the local donut/coffee shop 200 feet from our office. For the REALLY curious, here were my Q&A:
Q: What is the name of the button/link that you click when a task that you completed needs to go back on your work list?
A: Recall or Actually, I'm not done yet (the designer who got this correct actually named BOTH!)
Q: Where do you go to find a list of ALL your recently completed tasks?
A: Navigate to your profile, then Accomplishments tab (This one was a struggle for them, even though I had watched one designer do it the day before! Haha. Another designer said "Your list of tasks awaiting approvals??" which is somewhat correct, but also makes me wonder what the hold up is on my feature request of adding the Accomplishments tab to the My Work page!! ;) )
Q: In what situation would you click “Done with my part” rather than just “I’m done”? (This one is pretty specific to our company)
A: When you are a designer assigned to a task along with a production manager or a second contributing designer or a copywriter assigned to a task with a designer (Not surprisingly, a copywriter was the first/only person to get this right, which means that I haven't yet successfully drilled this best practice into the designers' heads!)
Overall, I think it was a VERY successful way to briefly remind our team of some important Workfront features/best practices in a way that was engaging and fun, and it only cost the company $15! ;)
I've attached my presentation for all the nerds like myself who love a good training deck.
