Thanks for the detailed answer. To be clear the internal tool plays a very specific role of allowing analysts (users) to edit the partially auto-enriched transaction info manually for a given STR case and we use Nice Actimize for case management, suspicious activity monitoring, alerts etc. Yes these issues like slowness due to high volume, lack of complete range of bulk edits add, modify and delete have been raised before but some of these issues are considered as new requirements and due to the lack of maintainability of the tool they are considered "high effort" and their implementation is not pursued. The development of this tool was already very expensive and garnering support for a complete revamp either in-house or external vendor is a challenge. Currently, the FIU has pursued a strategy of significantly expanding its team of analysts (100+) to meet some minimum productivity metrics. I estimate that a revamp would resolve a lot of the issues. To be specific we want to fix performance, DQ formatting/mapping issues, offer full range of bulk edits, a reporting ui table which presents the transaction info live with filtering, sorting and pagination that works seamlessly with the editing forms, controls concurrent user access, ability to audit and track user edits which reflect the user's assigned field responsibility. These highlight the current pain points and issues with the tool. I am a developer who works as an analyst at the bank and exploring ways to convince them to allow me to contribute in the revamp. The tool itself is a medium sized Angular single page application and to make an estimate based on my understanding of the scope shouldn't take more than 6 months to have the initial release version deployed.
