Do you have any tips for reducing time-to-value for customers?
Before you can worry about reducing TTV, you need to make sure you have clear definitions of what that value means. The sliding scale of standard to fully custom will depend on your product: commodity out of the box all the way up to an enterprise platform.
Once you have a clear definition of value, publish to your customer a plan about how to capture that value on a timeline. The crucial part? Who owns what piece.
The most common blocker to TTV is your Customer not know what to do when. Start always with simple messaging while the sale is fresh and important to the Customer: you paid x to get y. This plan gets you the value you want in the quickest time period.
The biggest mistake made is when vendors don't follow the plan and hold the Customer accountable for their side of execution.
