Matthew du Toit worked for Decipher Consulting from February to June 2016 to help increase productivity at a gold mine in California. He developed a system to consolidate disconnected data from the mine's truck fleet and display it interactively. Matthew also performed analyses to identify areas for improvement. His engagement with the data and critical questions allowed the team to focus on critical path analysis, increasing truck productivity by 27%. The managing director would happily re-employ Matthew due to his valuable contributions.
