Hi.
Our team tends to fail certain types of items. One example is when we finish almost everything needed to close the item but at the finish line some external blocking issue occurs. These are fully out of our scope. Like some tools fails to work properly and by the time they are sorted out its already too late.
We can't count with this at planning, because these are random external issues.
How to handle this? Should we somehow modify or DOD? Or change the commitment every time so we can deal with the unexpected dependencies?
Thanks in advance.
