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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"They have in-built connectors for connecting to various systems."
"Scalability-wise, I rate the solution a nine out of ten. Celonis is a wonderful tool, so you cannot find any drawbacks at the right moment."
"Celonis is a great tool and is clearly the leader in process mining."
"The analyst role within this solution is very good; it provides a transaction dashboard, and KPI module, that are completely customizable."
"The dashboards are excellent; they really do a good job of giving the best patient data and they help us to discover insights."
"The process mapping is most valuable to us."
"The solution offers very good division management."
"The product helps clients visualize potential savings by minimizing human errors and reducing manual work."
"The most valuable feature of Process Mining Group ProM is the toolkit it provides all kinds of variants of process mining. They have one option that you can visualize which processes you mine, and that's a very powerful tool."
 

Cons

"They are killing the customers with high licensing prices. The tool’s pricing could be cheaper. Small enterprises wouldn’t be able to afford the tool."
"I have experienced lags in response times from customer service. We are not always receiving responses on time."
"The support costs are very high."
"It would help if they had more integration flexibility and automation features."
"The only problem is the price; it is a little bit expensive when we compare it to others."
"Celonis is not entirely stable."
"The Process Query Language (PQL) native language used in Celonis needs improvements. It has most of the process-related functions but we have queries from clients that cannot be done in PQL."
"The cost of Celonis is not competitive when compared to similar tools on the market."
"Process Mining Group ProM could improve user-friendliness and the error messages that are provided are not helpful for end users."
 

Pricing and Cost Advice

"The cost would be a concern for a certain category of customers. Flexible cost models would help smaller players be able to adapt Celonis into their business operations."
"Celonis is a little more expensive than UiPath."
"Celonis is expensive, but it is functional."
"Celonis offers free learning possibilities. I am using the free version of Celonis."
"The solution’s pricing is high when compared to other process mining tools."
"The pricing is reasonable."
"It is only affordable for large or public companies."
"It is quite a significant investment. From a cost perspective, they need to reevaluate the licensing model. The cost is justified, but they need to make the licensing model slightly different."
"Process Mining Group ProM is an open-source solution that is free from the University of Eindhoven. Additionally, students can use it for one month after they have done some practicing with it."
