While Argyle Diamond Mine had an existing delay accounting system that was developed in-house, the challenges of a legacy system were exasperated by the departure of the in-house developer. As a result, the company struggled to remain up-to-date with the changes in the mining process along with advances in software capabilities.Due to changes in mining operations, a large number of equipment events were recorded as text data. This made it difficult to search for trends since the system was dependent on user input, which was not consistent across each user.The challenge for Argyle Diamonds was to determine which delay accounting system would be the best to implement given a limited budget and a well-defined set of needs: something scalable, capturing all delays at the plant level, with the ability to classify and search delay events.
