Appian and Celonis are competitive in the process automation and mining sector. Appian has the upper hand in rapid development with its low-code platform, while Celonis leads in process mining analytics.
Features: Appian enhances rapid development through its low-code platform, enabling quick deployment across various devices. It excels in process automation and data management, supporting rapid prototyping for fast ROI. Celonis specializes in process mining and analytics, providing powerful tools for process visualization and optimization, although it has a steep learning curve due to its comprehensive data analysis features.
Room for Improvement: Appian users seek more flexibility in UI design, enhanced integration with DevOps tools, and improved scalability and error handling. Celonis could improve its integration capabilities and make automation features more intuitive, with an emphasis on better task mining support and pricing adjustments for smaller enterprises.
Ease of Deployment and Customer Service: Appian offers flexible deployment across Public, Private, and Hybrid Clouds and on-premises, paired with highly praised customer service. Celonis is equally versatile in cloud deployment but requires enhanced integration. While it offers solid customer support, complex queries need better responsiveness. Appian's customer service stands out in competitive environments.
Pricing and ROI: Appian offers cost-effective solutions with various licensing models, generally yielding positive ROI through increased efficiency and reduced process times. Celonis is expensive for smaller businesses but highly valuable for larger organizations needing comprehensive analytics, justifying its cost when leveraged effectively.
Using Appian is saving us five full-time employees, which is significant since we currently have only four team members.
They see return on investment in terms of cost savings, time savings, more efficient processes, and more efficient employees.
The Return on Investment is significant.
In the first couple of years, I would not expect a return on investment because the initial setup will take more than a year if the process requires significant customization.
In my opinion, there's a positive return on investment.
I have seen a return on investment, especially in time saved for my clients; in the incident management process, the average cycle time for handling tickets was over ninety-eight hours, but after identifying root causes, such as tickets being held due to wrong group allocation, the cycle time reduced to approximately thirty-eight hours.
I would give Appian's customer support 10 out of 10 due to their next-level support.
Their customer service is responsive, and the team is very prompt for support.
The technical support for Appian rates as 10 out of 10 because they have a great support team.
It took more than two weeks to receive a response.
Celonis customer support is really good; they investigate concerns thoroughly and provide solutions or troubleshooting steps, which I find helpful.
Other times I do not get much clarity on the support from the team.
On a scale of one to 10, Appian rates as a nine for scalability.
Our volume has increased by 20% in the two years since using Appian, and it can handle the increased volume effectively.
Initially, without much coding, I can easily handle five thousand records.
I recall that when we started using Celonis, we had a space of five terabytes and around one thousand users, and Celonis managed all of that easily.
I recommend focusing on recent data or perhaps five years of historical data along with live data for better visibility and stability in the process.
At the moment, I'd rate scalability six or seven out of ten.
We have tested Appian during peak usage and off-peak times, and we have not experienced any issues such as lagging or system disruptions.
It depends on how it has been designed and how it has been configured.
The stability of Appian would rate as nine, as it's a stable environment.
It's super stable.
Celonis is stable.
It has room to improve for use cases where the users are public facing, where anonymous users could come to a site and run a business workflow or interact with some data.
Appian can be improved by adding a geo-location tagging feature, which would be really helpful for identifying remitter addresses.
It also suggests the best automation process that can be configured within Appian.
Ultimately, I need niche expertise, combining strong SAP knowledge with Celonis competency.
It is essential for the Celonis solution to have their services and solution models integrated with GenAI.
The most important area for improvement is the automation part.
Appian provides value for money, is easy to use, has a straightforward setup procedure, and offers great support from the Appian team.
On the pricier side, both Appian and Pega are enterprise-level solutions, placing them on the slightly higher side.
The pricing of Appian is based on the number of users and generally ranges from 70 to 100 USD per user per month.
I think it's relatively expensive, but it's also good.
Based on client feedback, I have heard that the pricing for Celonis is considered high.
creating a data model for one process will differ in cost if you add more data models for additional processes.
The zero-code integration feature is remarkable, allowing for ease of data transfer and workflow enhancement.
Appian is aiding in leveraging AI technologies in multiple ways: one way is for developers, as they make development efficient and quick by enabling developer co-pilots across various phases of the application, which helps design Appian quickly and provides suggestions along the way.
After switching to Appian, it can extract data from MT103, eliminating the need for manual data entry.
Celonis is also beneficial for its built-in apps that streamline tasks from legacy applications, facilitating daily operations and improving efficiency.
It provides a visualization of the process itself, giving a very good synthesis of performance and helping me find improvements.
It's the first solution that combines business competence and capabilities with technological capabilities.
