On March 13, 1999, Habitat for Humanity New Zealand built a fully operational, four-bedroom house in Auckland in 3 hours, 44 minutes, and 59 seconds from floor to roof complete with curtains, running showers, lawn, and fence. In doing so they became the fastest house builders in the world. The project took 14 months to plan. Critical-chain principles were applied using ProChain Software to finalize project schedule. The critical-chain was recalculated 150–200 times and analyzed to optimize the resulting new sequence of operations. This reiterative process was used to progressively develop the fastest plan.

Companies can learn from this example to effectively use project management principles such as Critical-chain to implement projects when companies are constrained by resources.
