Srimanta Pandit - PeerSpot reviewer
Flexible, improves operational efficiency, and reduces the time taken to complete processes
The solution’s turnaround time for development is better compared to other tools. The solution enables fast development. The traceability of the processor is good. There is much more governance and regulations on the processers. The tool reduces the time of the processes by 30% to 40%. The solution’s low-code aspect has greatly impacted the development and deployment speed. One of the major reasons we are using the product is that we can reuse the modules. The developers can reuse all the modules. It enables us to make subsequent developments in less time. The prebuilt modules can be deployed within two to three weeks. The tool is very flexible. Compared to other platforms, the Appian product team was agile in quickly customizing things for us.
Bireswar Das - PeerSpot reviewer
A low-code platform for the development of mobile and web enterprise applications
To illustrate a case, the customer initially had a private cloud, essentially a data center hosted within it. They needed a disaster recovery solution, which would involve using a public cloud. This situation led to some deployment challenges due to the hybrid nature of their setup. However, once we implemented the solution for them, they were extremely satisfied. The process was not only effective but also quite speedy. To be more precise, we completed it in around 100 days, even though they initially requested it to be done in four months. They were very pleased with the efficiency of the implementation.
