In a past life, I have worked as a MRO buyer and as a purchasing agent. As such, if you are reasonably competent at your vocation, you understand 'lead times' and how they affect your production output. At any time, I have seen lead times of six to twelve weeks and planned production taking those times into account. Going on six months though: someone is seriously incompetent, or perhaps an organization is credit challenged and on a cash only basis with vendors. Who knows. At a publicly held company, there would be new faces everywhere.
