The constraint can be found where there are queues of work in progress wip in front of specific equipment and therefore causes extra inventories. They include areas such as development languages, hardware, other infrastructure, and software that must be used for your project.

Theyre called assumptions because you assume that for your project to move forward successfully as planned, these things will be in place. But in reality, if there will be lots of bugs after the software is developed, bugfix efforts can exceed 20% and this can cause project delays or the budget may exceed.
