Process intelligence has transformed procurement and order cycles and delivers measurable savings
Celonis can improve in several areas. The initial data modeling and continuous real-time ingestion, especially from non-standard legacy systems, can still be complex and quite resource-intensive, requiring a steep PQL learning curve for non-technical users. Simplifying the interface for business stakeholders would significantly accelerate the process. I think introducing a natural language to query interface would allow business users to query data without writing long PQL. Streamlining guided onboarding flows and offering modular plug-and-play dashboard templates tailored to specific roles would shorten ramp-up time for daily users. I think more transparent and predictable consumption-based pricing models would be helpful as data volume scaling can get costly quickly. I would also love to see native, real-time streaming connectors for unstructured data such as emails and support tickets. The learning curve for new users of Celonis is one of the pain points I raised earlier, and I find it to be quite steep.

Powerful tool, beneficial process mining variants, and scalable
The initial setup of Process Mining Group ProM was easy for me. However, I have been an application manager for quite some time and I am not comparable to the average person. I was able to install the solution within a few minutes. Additionally, we use the solution for summer school, we have to develop course material around it.

"The most effective feature of Celonis is its capacity to analyze processes and uncover optimization opportunities through its visualizations of process variances."
"The solution really is a leader of the industry in the concept of process mining."

Cons
