Maintenance Break
Workshop Capacity: Same Bay Count, a Fraction of the Work
Pete ran the same fleet through two completely different ways to work out how many workshop bays a site actually needs for their mobile fleet and landed on the same number both times. The catch: one method took weeks longer than the other, and it wasn't the accuracy that changed. Pete and Drew break down zero-base (build it up task by taskfrom the full maintenance strategy) versus top-down (start from fleet availability and sort the downtime you already have). Zero-base gets you there, but its assumptions are buried across a hundred task lines, easy to quietly inflate the numbers to match what you need. Top-down is faster because the total maintenance requirements are already fact, and it comes down to a hand full of visible decisions on where maintenance on an asset happens. Break Tip If you've got an expanding fleet and need to calculate potential new workshop requirements, use a top-down approach and keep it simple by identifying the locations your maintenance happens. Work with the team to define what happens at each location and make reasonable assumptions on the allocation to each space.
