Group Head of Data Strategy & Enterprise Governance at a consumer goods company with 10,001+ employees
Struggled to justify enterprise adoption but have valued broader developer accessibility
If I could change or add anything to improve C3 AI, I would suggest making it not just an AI platform, but a data and AI combined platform, as bringing in data management elements, governance, and cloud features is critical. The real AI and modeling represent only 20 percent of what is needed; there is over 80 percent in the rest of the world that should be addressed. Given Tom Siebel's deep understanding of corporate work and his network, integrating C3 AI with other ERP solutions such as Oracle, SAP, or Microsoft is essential. If C3 AI can be an enterprise platform, embedding more data elements and ensuring seamless integration with other ERP solutions would significantly enhance its capabilities and attractiveness. If someone told me that they have SAP, and C3 AI can seamlessly integrate the data and perform action calls between SAP, allowing me to operate on C3 AI as I would on SAP, that would be a killer feature for me. I would suggest avoiding traditional licensing sales as it is too expensive; the starting price is too high. Considering a subscription model or a pay-per-use model is the best business structure for AI or data solution vendors. The pay-per-use model benefits usage, as the more you use, the more successful you become with the platform.

Process mining has delivered major savings and now needs better automation and task mining
Collaboration with ERPs should be improved. Compared to SAP Signavio, Celonis is less competitive for BPMN modeling. Deployment flexibility needs enhancement, as on-premises support is not as strong as SaaS support. The most important area for improvement is the automation part. End-to-end automation capabilities are desired. Currently, workflows are being used, but actions should be able to go via email, task, APIs, and ultimately write back to the source. Adding RPA capability that can interact with required systems and write back to the source would greatly enhance Celonis. Task mining capabilities also require improvement. UiPath Process Mining and Microsoft Process Mining have better task mining capabilities compared to Celonis. Usability and support from Celonis need improvement. They should help clients find more value in the product. Cost is another significant concern, as Celonis is very expensive compared to other process mining tools. The license cost should be reduced. Celonis should establish partnerships with clients to find more use cases and maximize the value gained from Celonis.

Quotes from Members

Pros

"One of the best features C3 AI offers is that you do not need to learn Python or any specific machine learning programming language; you can use C3 AI with JavaScript."
"I have noticed improvements in efficiency, reduced downtime, and time saved for my team, as it is quite integrated through the source ML pipeline to report to general customer UI, functioning as one platform that takes care of everything, thus improving efficiency, optimization, and increasing project deliverables."
"In the first phase alone, there was approximately $90 million in savings, which reduced about 5% of inventory."
"The most valuable features are process mining, task mining, business analytics, and machine learning."
"The most valuable features of Celonis are its graphical interpretation and pre-built connectors with industry platforms like SAP or Oracle."
"For O2C alone, we found automation opportunities for 7000 hours, making the ROI recovered within 9 to 11 months."
"Celonis is a great tool and is clearly the leader in process mining."
"Celonis is a very good tool that can improve your business process in a single package."
"For the amount of information that it processes, it works relatively fast. I like the visual presentation and the interface is intuitive. I also like that Celonis has a learning academy."
"The support we receive from Celonis is good."
"We use the tool for supply chain transformation. The tool has helped us find the bottlenecks in the supply chain like where the delay occurred in delivery, payment, etc. We had to extract two years' of data from the SAP system and an internal tool. We fed the data into Celonis and it created a process map for us with hundreds of variations. It has helped us see where exactly the bottleneck was. The tool has also helped us generate a lot of reviews and KPIs. It has helped us to find the problem and the remedy through process optimization."
 

Cons

"We even failed to open any doors for C3 AI; there are no smaller wins, learning opportunities, or process improvements, even if the main goals were not met."
"The reason I chose eight out of ten is that as a user of C3 AI, I found the operational aspect not easy to understand; it is a bit tricky, and you should have more core knowledge to navigate C3 AI."
"However, I sometimes hear from colleagues that hallucination is an issue."
"I'd like to see a couple of algorithms that can better identify the bottlenecks and provide a better view of those bottlenecks."
"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."
"It is not particularly flexible in the way it works, and it is quite rigid."
"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."
"The one thing that could be improved is the guides are not getting updated to cover new features and upgrades, which means we can't use them at their full potential."
"Similar to what SAP is doing with S/4HANA, Celonis should allow business users to create their own analytics tab. In my previous organization, business analysts were the only ones who were actively building these reports with Celonis, whereas SAP platforms are now allowing the business users to create their own reports with graphics and all other things based on the data that is presented. This is one thing that Celonis needs. Currently, just the technical teams are doing that. Sometimes, when we were looking at five years of data, it used to take up to 3 seconds. It wasn't bad, but we had to wait a little bit. It probably also had to do with the server. I don't know if it can be used on mobile devices. If not, that will be the way to go. They should mobilize it to allow people to see these reports on their mobile devices."
"I believe Celonis could provide more detailed documentation so that users do not struggle to understand the tool, as the resources are somewhat limited."
"In the next release, I would like for them to integrate more custom features to ease the process of having multiple solutions. I would like to be able to integrate it with other solutions."
