How can you ensure data quality with cross-border portfolio management?
Classify data sources - data from the original source vs data from an intermediary/third party. Try to maximize the ratio of collecting data from the original source. Utilize a central storage for all use cases, so to eliminate the risk of internal inconsistencies. Apply not only technical checks on structure and format of information, but logical check across between multiple data points also. Enhance these controls by a validity date by when a given information is expected to be updated from the source the latest. Use state of the art tech to be independent from source format and manual intervention in the data integration process. Don’t underestimate the cost and complexity building this in house - rather partner with specialized firms.

What are the most common reasons for an ML model to fail in production?
Measures to ensure data quality may vary between external third party vs internal proprietary data. For internal data an organization has the reassurance to work with golden source information. Applying a strict data governance, with clear definition of owner and the lifecycle of an information is key. Given this is ensured the data provided to a model can be considered as „high quality, first hand information“. In regards to third party data, that firms may use to train a model, the source of information is critical - is the third party the original owner of the information or is it a firm in the middle, collecting the data from other sources. In the latter case a second source may be used for the same data to verify its quality.
