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

"From a features perspective, the discovery and analytics parts of Celonis have been valuable, especially the analytics and all of the out-of-the-box process connectors."
"For O2C alone, we found automation opportunities for 7000 hours, making the ROI recovered within 9 to 11 months."
"Celonis assists me in optimizing processes, reducing throughput times, and identifying automation opportunities."
"Celonis' best feature is a new one called Action Flow, an enhanced version of earlier automation features with lots of integration options with other systems so you can access third-party systems and automate some actions there too."
"Automated root cause analysis and process explorer features are very good. It provides a lot of selections, such as process flow selection, attribute selection, etc."
"Celonis is a good idea to change the way processes are considered in a company."
"Celonis has helped me to identify and prioritize process improvement areas. Because we understand the end-to-end lead time, including waiting times and areas where rework happens, we can see the performance bottlenecks."
"In my opinion, it's quite an advanced tool."
"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

"Celonis is expensive, but it is functional."
"Celonis is good, but it is not comfortable for the India market. I am from India, and the Celonis CPM is not compatible with our country's cybersecurity policy."
"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."
"With every upgrade, the product is completely changed."
"Licenses are costly and calculated based on APC and the number of users."
"They should provide a community edition license so that everyone can deploy or install it on their own system and get more hands-on experience with the product."
"The data modeling features could be more intuitive."
"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

"Celonis is expensive. It's not for mid or low-sized enterprises because the license price is high. Overall, it's quite pricey compared to anything else that I have heard about. But the good thing is that they don't charge per user. They charge for the data model."
"The product is pretty expensive but reasonable."
"Celonis offers free learning possibilities. I am using the free version of Celonis."
"Celonis is a little more expensive than UiPath."
"Once we try to scale it up, the product becomes expensive."
"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 pricing is reasonable."
"Celonis has the highest pricing in the process mining domain."
"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."
