I have been involved in assessing various tools for personalization and optimization in my company. Unfortunately none of the comparison had Pega even included in the list - the most common one was Adobe target / Campaign etc.
Now I understand Pega Adobe integration provides a viable solution but where do we stand in terms of providing complete solution to personalize experience for an online customer ?
