Moreover, once you have structured all this information into a clear diagram or table, you will have new ideas on how to improve the product itself and the quality of interaction with the target audience.
CJM is useful at the product launch, when it is not at all clear how the audience will perceive it and what can go wrong. Or if you already have a product, but you are not satisfied with the results of sales and feedback from users.
Also, with CJM you can evolve and improve the quality of the product and reach new levels of sales and volumes of business, even if you are doing well. Also, CJM gives you the opportunity to build a foundation for your sales funnel and systematic marketing.
