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

"It's the first solution that combines business competence and capabilities with technological capabilities."
"They have a very unique product because it gives the user a dashboard, and end-users can easily evaluate the differences and get the required output."
"The solution offers very good division management."
"What I found most valuable in Celonis is the ease of use. I also like that users can compare and contrast and derive any KPIs, keep track and see what's happening within the process via Celonis."
"The solution has very detailed documentation for technical items so it is very easy for developers to use."
"I like that the product allows users to connect to different source systems like SAP, ServiceNow, and Salesforce."
"We are trying to optimize all of our organizational processes with this solution, and it gives full visibility of how a process is run end to end."
"Celonis is intuitive, powerful, and user-friendly."
"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

"It requires specialized expertise to set it up in the backend. I need knowledgeable data and process people who understand the tool and also my processes."
"There are a few things about Celonis that need improvement."
"Usability and support from Celonis need improvement."
"Celonis does not provide a detailed picture of user activities within processes because it relies on event logs from ERP systems."
"The marketplace should offer process connectors for Oracle JDEdwards, and Peoplesoft."
"It is not particularly flexible in the way it works, and it is quite rigid."
"We would like this solution to be more flexible in how it interacts with other cloud-based database solutions, so that we can operate more seamlessly."
"It would help if they had more integration flexibility and automation features."
"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

"It is only affordable for large or public companies."
"The solution’s pricing is based on APC. It charges you based on the amount of GV that you use."
"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."
"The solution is expensive."
"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."
"Evaluating the price of the solution can be a difficult question. It is all about the business case and the return of the investments. That is typically how we also see this type of solution. It depends very much on the return. The entry-level is focused on enterprise size companies, for the SMB segment is it is out of their range. It is definitely expensive."
"The solution is quite expensive."
"Celonis is a little more expensive than UiPath."
"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."
