Is there a word in English for sticking to a schedule
In the context you have described I would suggest the word you are looking for is 'Punctuality.'
Punctuality: Exact observance of appointed times; the fact or habit of being on time. (Now the usual sense.)
This is sense 'C' in the OED, with the other senses largely obsolete or now rare.
I think the "management" sense of the German word is more appropriate in this context. (from ‘Linguee’)
With this in mind, I checked the OED and its first entry for “management” is:
- a. Organization, supervision, or direction; the application of skill or care in the manipulation, use, treatment, or control (of a thing or person), or in the conduct of something;
under which it notes an early connection in English between “handling” and “management”:
1598 J. Florio Worlde of Wordes Management, businesse, handling, negotiation.
Although not single words, perhaps either "Shift Management [skills]," as used by ClickSoftware Technologies, a privately held company, headquartered in Israel ...
... or “Break Management [skills],” as used by the German company Hauni Maschinenbau AG, could describe what you want to measure, but admittedly, neither of them would describe the measurement itself, as you request.
To do that, I think you’d need to devise and furnish your customers with a relevant check-list or rubric for measuring such skills.
I like timekeeping here. Defined in the Oxford Learner's Dictionary as
- a person’s ability to arrive in time for things, especially work
Poor timekeeping and absenteeism will not be tolerated.
