Delivery dates keep changing

Understand which upstream changes make customer commitments unreliable.

01 · What is usually happening?

The first date was a good guess. Then material arrived late, a machine stopped, an urgent order jumped the queue. Each change was small and each was told to the customer separately.

The customer now ignores the date they are given and calls instead.

The question people usually ask“Why does the delivery date keep moving?”
The more useful question“Which cause moves the date most often, and who can remove it?”
02 · Common causes

  4. 04Quality holds appear after the date is promised
