Easy of use interface with very basic user features such as text fields to advanced functions like formulas or rule sets it has everything I would need when working on complex problems. Can be easily used by new employees and seasoned professional alike! Notable things about this software is how well they have implemented their customer service department through phone support, live chat, etc. This gives me all confidence not only in my choice in decision rules but also knowing they will help guide me should I run into any issues along the way. Would recommend using if you're looking for something simple to get started with however there are many modules with addtional tools available allowing you to customise exactly what you want. Needing an account system so you cannot login/logout without logging off. Using a desktop program that requires having client details online which is cumbersome at times especially The most important thing I like about this software it's simplicity of use as well as its ability to run complex calculations very quickly with little effort from my side. Nothing particular but if there were some minor improvements such as better customization options or maybe even an option where we could export our data into other applications (like Excel) would definitely help us out! We're solving problems related mainly to pricing analysis using decision trees within DRS3D platform.
