Sentiment score
6.3
OutSystems' ROI varies, with rapid development and reduced costs leading to high returns and improved customer experiences.
Sentiment score
7.8
Organizations using Temenos Quantum report increased development efficiency, cost savings, improved security, seamless integration, and scalable architecture benefits.
It's not that they're really firing that personnel, but they can often focus on the core that really matters instead of repetitive processes in Excel forms and all of the overhead and human error that comes with that.
CTO at Blue Green Solutions
Since Mendix is a low-code platform, the ROI is significant; we save a lot of money and require fewer people to do an application, reduced to two, which drastically decreases development time because this is not traditional programming; just drag and drop, and we can complete projects that would take years within months.
SOFTWARE ENGINEER at Siemens Industry
I have seen a return on investment with Mendix, as in default software development, a team with 10 developers or more is needed, while here we can do it with one or two developers, so it is truly a money saver for the company.

Room For Improvement

Setup Cost

OutSystems is costly for small businesses, but valued for its robust enterprise features compared to competitors.
Temenos Quantum is costly, with prices ranging from $70,000 to $500,000, though some users find it affordable.
The app license costs between $13,000 to $14,000, which is prohibitive for startups.

Featured Reviews

Mitchel Mol BGS - PeerSpot reviewer
CTO at Blue Green Solutions
Has improved development quality and speed but has introduced persistent IDE slowdowns
In recent years, the IDE has been more buggy and slower, and although there have been more features added, I would like to see more stability, as some areas that used to work for a fairly long time are now slower in my development, which feels like a step back. I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable, and the overall output on Mendix platform is still good; there is definitely some room for improvement, and I would probably have given it an eight or even a nine if those issues weren't hurting my developer output for the past few years. Overall, Mendix platform is stable, but the IDE could be better.
Aditya Bhatt - PeerSpot reviewer
Senior Technical Lead at a pharma/biotech company with 1,001-5,000 employees
Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects
Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.
Zain Omer - PeerSpot reviewer
Software Engineer (Kony-Temenos | Android) at Xpert Digital
Though a secure tool for building applications, there is a need to improve its stability
There is a lot of room for improvement in Temenos Quantum. Temenos Quantum is not quite stable yet. Improvements can be made to make Temenos Quantum stable. Improvements are needed in the solution, considering how my company needs to raise a lot of tickets with the technical support team of Temenos for some basic issues every time. There are some features in Temenos Quantum that I want to be stabilized by Temenos, just like in Android Studio and Xcode. Building an application using Temenos Quantum is not difficult, but my company needs to seek some support for the solution all the time.
