At the moment, I'd rate scalability six or seven out of ten.

It's super stable.
 

Room For Improvement

Appian needs improvements in flexibility, integration, scalability, team collaboration, mobile features, documentation, licensing, and handling complex processes.
Celonis requires improvements in flexibility, user-friendliness, integration, automation, interface, pricing, communication, training, and compatibility.
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.
I would like to see more enhancement in the user interface to allow more freedom in designing the sites and pages.
If there is a very complex process that includes a lot of data transitioning and memory-centric processes, it consumes a lot of memory.
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.
Changes in Celonis are packaged as assets, and when I publish an asset, it applies to the entire package, which makes tracing history difficult.
 

Setup Cost

Appian offers flexible pricing with cloud and on-premise options, but costs can rise with usage and require negotiation.
Celonis pricing is high, suitable for enterprises, and varies by data use with partner and user-cost differences.
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.
The price of Appian, on a competitive landscape, is a little bit on the higher side for companies, rating maybe a 6.5.
Based on client feedback, I have heard that the pricing for Celonis is considered high.
I think it's relatively expensive, but it's also good.
 

Valuable Features

Appian provides low-code development, easy integration, scalability, and strong AI-enhanced features with a user-friendly interface and robust support.
Celonis enhances process optimization with user-friendly interfaces, powerful analytics, automation, machine learning, and seamless integration capabilities.
The zero-code integration feature is remarkable, allowing for ease of data transfer and workflow enhancement.
Appian also utilizes AI for business users, providing a feature called process each view, enabling business users to create their own dashboards, reports, and gain insights from their data and processes using artificial intelligence.
I can create tables, perform database-related activities, and create multiple tables.
Celonis is also beneficial for its built-in apps that streamline tasks from legacy applications, facilitating daily operations and improving efficiency.
It's the first solution that combines business competence and capabilities with technological capabilities.
It provides a visualization of the process itself, giving a very good synthesis of performance and helping me find improvements.

Featured Reviews

RAVIRANJAN - PeerSpot reviewer
Low-code with good reliability and good workflows
We have a partnership with Appian. We have worked with Appian to deal with issues. They have already incorporated many things into their platform. One of the things we have discussed, which I can highlight, is related to Excel manipulations. They have incorporated their Excel manipulations so it's far better than the earlier version. Earlier, we had to go with a plugin for even a simple Excel or spreadsheet calculation. Now, they have included all those things in their own out-of-the-box functionality. It's definitely a tool and does not require high code language. There could be a scope of enhancement for capturing the variety of use cases. One thing, for example, is Excel manipulation, which they now provide in their out of box functionality, however, that can still be improved.
AntonioCardone - PeerSpot reviewer
Enables a data-driven approach to process analysis and helps generate cost savings
This tool allows me to discover value before discussing technology. It's the first solution that combines business competence and capabilities with technological capabilities. With Celonis, I discuss processes and root causes, analyzing the bottleneck resource process. There is an app centered around a data-driven approach. I can create the model and, in a data-driven way, map processes using technology that supports people in investigative activities by finding root causes where processes falter. Celonis emphasizes that these goals aim to generate cost optimization.
