I would like to suggest the solution but it really depends on your specific requirements, your business use cases and future plans. There is a significant investment involved in this solution and therefore it is very crucial to reevaluate your future necessity including automation potential and modernization plans. I would suggest that you select any kind of solution and explore alternatives of similar functionalities at a lower cost. This might help you to achieve more with less. In my experience, I would rate it between seven to eight because it offers robust capabilities. But please be aware that other BPM tools are emerging with similar features at a lower cost. Pega CRM is perceived as bulk care compared to order tools, as many of its capabilities are potentially underutilized. I would rate it 7 out of 10.
