Oh, honey, I've seen this movie before. Pick ONE workflow - content sharing OR deal tracking, not both. People can barely learn one new habit without melting down. Don't try to turn your team into platform wizards overnight.
Find the two reps who actually give a toss and make them your champions. Their wins will sell the tool way harder than any boring training deck you throw together.
And for the love of all that's holy, skip the feature parades. Show them the one thing that saves them ten minutes a day. Let curiosity drag them into the rest - don't force-feed it.
Most rollouts tank because leadership thinks launch day is the finish line. It's not. The real work is the first 90 days of nudging, hand-holding, and begging. Good luck.
