Omnichannel Customer Journey Map and your product metrics
It can take a long time from multi-channel interaction to the omni-channel world. You should always track your every step, every activity, and measure every effect of each change you make.
Customer Journey Map can help you not only to see your customer interactions through all channels, but to serve as a great dashboard that will allow you to track your key metrics. It will also allow you to see, whether you are still on track with your goals and overall direction.
