Sr. Project Delivery Lead | Sr. Technical Lead at a manufacturing company with 5,001-10,000 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.

Has provided a quick way to build mobile apps and could improve usability for non-technical users
The best features Retool offers include the ability to quickly create a mobile app and use this mobile app in a native mobile app for Android. I found the process of creating and deploying those mobile apps for Android with Retool to be smooth as the documentation is very good, and I found answers and examples to create a mobile app. I can access a debug mode in the mobile app which was really convenient to make tests and find what can be improved, where I have a problem, and how to correct it. Retool positively impacted my organization as the proof of concept we built gave us a way to convince power users and key users before developing the real software. It was a way to maintain the launch date of the project, which helped speed up the project timeline and save resources.
