About
Maintenance Untangled is run by two practitioners who have spent their careers on the tools, in the planning office and in front of the data.
Derick Martins came up as a Mechanical Supervisor and now coaches maintenance teams through Asset Optimisation — better workflows, healthier cultures and leaders who get their lives back.
Ricky Johnstone runs Johnstone Business Intelligence. For over a decade he has helped organisations improve performance by aligning people, processes, systems and data so teams can work from the same understanding, make better decisions and move in the same direction.
Together they cover the whole picture: the people and process side of maintenance, and the systems and data that prove it is working.
