Featured Reviews

Shad Bhowmik - PeerSpot reviewer
Finance Specialist at a government with 5,001-10,000 employees
Automated remittance workflows have boosted speed and accuracy but still need geo-tagging improvements
Remittance is a crucial part of my integral operation, so any disruption would majorly impact our clients. After switching to Appian, we never faced any disruption as it is reliable and we can generate data at any point in time, quite faster than other tools in my personal opinion. Regulators can ask for data from us at any time, and with Appian, we download data from our Appian tools to share it with them whenever they ask. I would share a real-life example: a customer's transaction processed more than a year ago. Suddenly the customer came back asking for all the details. In our previous tool, it was quite difficult to generate transaction details from over a year ago; however, while using Appian, we can pull up data using different key search fields, such as a customer's cell phone number, remittance tracking number, or MT103 reference number. We shared it with the customer instantly, and the customer was surprised we could provide all the details in such a short time. It added reputational value for our organization, thanks to Appian.You have pointed out two major things: time-saving and reduction of error, which are key points while processing remittance. Previously, while using another tool, it was quite time-consuming to process remittance, but after switching to Appian, it can extract data from MT103, eliminating the need for manual data entry. The process has become fully automated. Previously we could process only five to ten transactions within an hour, but now, after switching to Appian, we can process about 100 transactions in an hour, making it 10 times faster. In terms of error detection, since Appian extracts data from MT103, the extraction rate is quite good, and the error rate is negligible, lower than 0.001%. We can share accurate, error-free data with the regulator, which is essential for us. Appian benefits us significantly. After receiving an MT103, we check what the remitter is, the amount, if it is under threshold for processing, and if it is from a high-priority remitter or client. Since Appian extracts data from MT103 messages and identifies top-level clients from the database, it can notify us to process their transactions with priority. Due to automated data extraction, there are fewer instances of error. In our previous tool, we reported regulatory data to the central bank manually and often received complaints about invalid purpose codes due to manual data entry. Appian handles this automatically, and after switching, our error rate has dropped significantly, resulting in positive feedback from the Central Bank of Bangladesh regarding our reduced error rates. This has greatly enhanced our organization's reputation. Appian is fully on-premises, and we have our own system.

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.

Structured workflows have improved SLA compliance and now support prioritized incident handling
I think the licensing and pricing of ServiceNow is quite expensive compared to other tools. For large organizations, it is acceptable, but specifically for small and medium organizations to track incidents or change requests, ServiceNow is quite expensive. Sometimes performance can be slow when workflows and integrations are configured for complex tasks. For advanced customizations or advanced features which we rarely use, the documentation is not up to standard. The documentation needs to be improved for advanced customization features. However, the platform is stable overall and the features are quite good. The user experience and performance concerns I mentioned are areas I want to be improved. When many workflows and interactions are configured, performance is slow. For the features it is providing, it is quite expensive. If these performance features are improved, we can easily pay that price and get the return on investment.
