The best feature in UiPath is their robotic enterprise framework because that is an inbuilt processing framework for utilizing their work queues. It's plug-and-play, and already pre-built to where you don't have to start from scratch. It's enterprise-grade and ready to be used. All you need to do is populate your dispatcher, create a queue, create a performer, and you're good to go.
The highest benefit of it is that it's just there, ready to use, and you don't need to start from a blank screen. You don't have to figure out, for example, how to create an environment where the robots can check if there's anything in the queue to be worked on. The framework is already there. The other tools that I've used, like Blue Prism, don't have that built-in quite as well.
My perspective and overview are from that of a developer, and I find that the recorder feature is really good. This is because UiPath lets you record your actions on the screen. So, if you want to interact with a web-based interface, for example, then you have UiPath record your actions and then build the activities that you would need in order to replicate those actions through the robot. It makes it a lot better and although it's not perfect and it does need to be reviewed and adjusted, it speeds up development quite a bit. This is especially true when it's basic back development like populating fields and clicking buttons and navigating on a web.
Compared to other RPA tools that I have used, something that stands out to me in UiPath is that it has a very extensive library of activities. Those activities are easy to search for and use.
When you are writing code, there is a feature called IntelliSense, which autocompletes your code. More specifically, when you're typing code, if you're starting to type the name of a variable, it will show you all of the variables available and you can just click them. It's very interactive and it's reminiscent of the Microsoft Visual Studio environment, both from the UI perspective and the coding perspective. This means that developers that are familiar with Visual Studio will probably feel right at home using UiPath. It's very developer-friendly and it's geared towards appealing to existing developers.
The UiPath Academy courses definitely help in the process of bringing employees up to speed. The Academy is the go-to place for UiPath learning and I think that other RPA tools are copying this model of disseminating knowledge, being a lot more open with training, making it freely available, and providing an online classroom. These are things that UiPath has always done, and it certainly helps new developers get upskilled in RPA, and specifically with UiPath.
When it comes to ease of use, UiPath is intuitive insofar as the basic features have a low learning curve. However, if you want to take full advantage of what UiPath can do, and if organizations want to create more sophisticated automation solutions, it is more difficult. For instance, automations involving back-end access, maybe writing directly to databases such as SQL or using API, that's a steep learning curve. In fact, I think the learning curve is exponential.
If you just want to make a robot that sends an email, that's really easy to do. But, if you really want tangible benefits, like if you really want something that solves a business problem, it is a huge learning curve and it takes a while to master. Obviously, it does have that low-code requirement, but I would say that's only for entry automation projects, like proof-of-concept or something along those lines. For something that really solves a business problem, you would need code, because that just makes it a lot more robust and a lot more powerful if you can custom-code certain steps of the process.
