Every step earning its place.
WASTE · BOTTLENECKS · REWORK
Waste, bottlenecks and rework stripped out — every step earning its place.
9D applies lean thinking to the model — finding the waste, the bottlenecks and the rework, and stripping them out so every step earns its place. It is process engineering for the build itself.
Like the other later dimensions it is powerful but not yet fully standardised, so it is specified to the project rather than assumed.
