Seamless integration enhances workflows while memory optimization can improve complex processes
I am working with all of these products: Pega, Appian, and OutSystems. I use Appian as a process orchestrator for workflow and rule-based routing, and it is preferred when I am developing an enterprise-wide application. The application is mobile-friendly, allowing me to use it across any device…
ND
Flexible and granular security options, good filtering, and the pricing model is cost-effective
The vendor does a really poor job of marketing this software because it should be more popular. This is something that I have pointed out to them. It's a super piece of software, but very few people are aware of it. I am an EX-IT director and I've worked in big systems, and I'm amazed this solution isn't more popular. The "native" integration with other products could be improved. The user interface for the systems that you build can use some improvement because as it is now, you may have to use HTML and CSS to make it look more modern or to match a clients existing look. The documentation is amazing, although they don't do videos and their YouTube channel is very poor. They could create some training videos.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There is no need to worry about vulnerabilities in the system, because Appian built a secure system​."
"What stands out are the speed of the product, the quick, easy development, and visual diagramming."
"SAIL (Self-Assembling Interface Layer), a scripting language provided by Appian. It is the equivalent of JS and CSS. It allows creation of complex UIs which are also responsive. With SAIL, we have a single language for both the UI logic and its appearance. UI components can be built as reusable components and used in multiple UI interfaces."
"Appian's most valuable feature is that we can create end-to-end process workflows with minimum turnaround."
"The most beneficial aspect of Appian is its data management capabilities and the process engine in general."
"The initial setup is easy."
"It has created executable requirements and speeds up the SDLC process greatly."
"The most valuable features are the low coding and low code data."
"The security is the most valuable feature, in particular, the way I can give different access to different areas to different people, so you can really fine-tune access for different users."
 

Cons

"The performance is pretty good, but the distortions need to be optimized in order for it to work well."
"If there is a very complex process that includes a lot of data transitioning and memory-centric processes, it consumes a lot of memory."
"I wouldn't say their response time is long, but it could be quicker."
"Architecture of product and scalabiility issues."
"There are four areas I believe Appian could improve in. The first is a seamless contact center integration. Appian does not have a contact center feature. The second is advanced features in RPA. The third would be chatbot and email bot integration—while Appian comes with chatbot and email bot, it's not as mature as it should be, compared to the competition. The fourth area would be next best action, since there is not much of this sort of feature in Appian. These are all features which competitors' products have, and in a mature manner, whereas Appian lacks on these four areas. I see customers who are moving from Appian to Pega because these features are not in Appian."
"We'd like improved functionality for testing new devices."
"The solution could use some more tutorials to help brand new users figure out how to use the product effectively."
"Appian has a few areas for improvement, which my organization raised with the Appian team. One is the Excel output which is limited to fifty columns when it should be up to two hundred or three hundred columns."
"The user interface for the systems that you build can use some improvement because as it is now, you have to do a lot of HTML and CSS to make it look modern."
 

Pricing and Cost Advice

"The cost depends on the number of users, although I recommend taking an unlimited license."
"The license is not very cheap. It's on the expensive side."
"The license is a bit expensive and the pricing model is sometimes confusing for new users or business users. It is difficult for them to know what volume of usage they will have to be able to purchase the best-suited license at the beginning."
"The licensing will be on a monthly basis. We are estimating that cost to be around $2000 to maybe $3,000 per month. We don't foresee any costs above that."
"The price of the solution is reasonable and is paid annually. The price of the solution depends on how many users use the solution. It can range from $50,000 to $200,000. For example, for 20,000 users the price can be approximately $200,000."
"The tool is quite costly."
"When it comes to pricing, it's definitely not affordable. However, it really depends on the requirements that you're seeking from the solution."
"The price of this solution is a little high here in Mongolia."
"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
