Appian

Appian is very well suited for complex business processes. If implementing using traditional methods is daunting, then Appian would be a good alternative. It follows that simpler business processes would be a breeze. Also, it's well suited for situations where sharing data across processes/applications is likely. There's no need to "integrate" from Appian app to Appian app, so sharing data within the platform is trivial from a technical implementation perspective. Appian may not be as well suited for dealing with very large datasets (tens of thousands of records), it seems too much data may start taxing the system.

OutSystems

OutSystems excels with building web interfaces fast and lends itself to custom integrations written in .Net. Most anything can be brought in given this ability to be extended. One of the drawbacks to the speed of development is that most quality control teams become quickly overwhelmed and may be unable to keep up.

Pros

Appian

  • I have observed after version 17.1 we have a lot of good features in Appian that improve usability (UX). This adds real value in this competitive Digital space.
  • You can understand business use case and convert it to a logical process automation.
  • Process Modeller has improved a lot and providing smart services use adds more value.
  • Service integration helps us to seamlessly integrate with third-party systems

OutSystems

  • Deployment management – OutSystems has a built in robust, multi-environment deployment system that helps ensures the clean and error free deployment of applications through the development, testing and production product lifecycle
  • Rapid application development – Through the low code, graphical development environment you can develop applications far quicker than with more traditional development environments
  • Cross platform mobile development – OutSystems handle the development and building of mobile application for both iOS and Android in a simple streamlined way that removes 90% of the problems normally associated with multi platform development

Cons

Appian

  • Appian is continually improving the product but having to learn new features every 3 months (upgrade schedule) can be a challenge.
  • Graphical user interface could use some additional improvements but it has come a long way already.
  • Sites could use some additional modifications. Currently, the News Feed is not available on a site.

OutSystems

  • The platform controls all the parts. While great for development and overall maintenance, it could lead to discussions with your DBA (who has to trust the platform). As a developer I love the platform, as a DBA I would like more control.
  • By making software development model driven using flows, you are forced to rethink the way of programming. It makes it easier, but sometimes the way of working leads to code which could be optimized (standard problem in model based software development).
  • Most of the code is generated, so the technical knowledge of the inner working of coding are not Essentials. This could lead to degration of this knowlegde. As part of this, most technologies will only be used when OutSystems supports it. They do a good job on implementing these things. But things like Node.js would be nice.

We recently renewed our license with Appian. We are convinced that its flexibility, relative ease of use, the support they provide, there mobile advancements and their general willingness and desire to see us succeed all contributed to our reason to renew our agreement with Appian

We are very happy with OutSystems and our developers deliver good work. OutSystems lets us build new software on a regulare (2 weekly) basis, which is highly flexible and adjustable. Even without very much experience, our developers manage to build usefull software, which is working a lot better than our previous (legacy) software.

The interface is as difficult to use as you make it. We like to follow the KISS principle and automate the mundane so that our staff can concentrate on their day job and not have to worry about what happens next.

I am really happy using OutSystems in my work. It gives me the opportunity to create good working software without having had very much IT-experience before. It also made me more interested in the background of IT and learning different languages.

We have Appian support here full time who are always helpful and understand both the products and our needs. They help guide the product to help it stay stable.On the odd occasion we need to call Appian themselves, they have always been responsive and genuinely want to help us solve the issue.Recently I've needed to send in quite a few support tickets for various issues, none of them were critical and 2 or 3 of them were just questions. Each time I got a response very quickly and each time the help was what was needed.

In becoming bigger, the support encountered several growing pains, but we've seen amelioration (also by involving a customer engagement manager, more direct lines with OutSystems, and better contact with partner Noesis). Sometimes growing goes fast and the organization needs to adapt to the new world. New markets are conquered, but others still need to grow.

Alternatives Considered

Appian

The main advantage of Appian is the cost structure that is more suitable for starting a test-project to see how develop in Appian and most of all how Appian is accepted inside the company. In few weeks you can show the first results and start the journey on digitalization.

I tried to use WordPress with some success. Also looked at Joomla. But when I saw OutSystems I knew I had been wasting my time there. It takes you longer to get going with OutSystems - but even I as a novice realized immediately that Outsystems is simply in another league. Outsystems is powerful. (Can you compare WordPress and Joomla to Outsystems - I don't think so).

Return on Investment

Appian

  • Our objective to reduce customer effort when dealing with government by 25% was exceeded. In the process of applying for an alcohol licence renewal alone, we saw approximately 80% reduction in time and effort for the business customer - and that was just a prototype! Imagine the possibilities when this is taken into a live environment!

OutSystems

  • The ease of use of the OutSystems development process has been the biggest ROI for us. We have developed our Framework product and maintained/enhanced it with only 4 workers.
  • OutSystems has enhanced their product very significantly over the last 4 years. They have gone from a simple to use tool to a very simple to use sophisticated tool that covers the standard mainframe-based computing apps and the apps used on handheld mobile devices all using the same basic set of development tools.
