The word "runtime" appears in contexts related to computer programmes as a noun for the time when a programme or part of it is executed. So far, so good.
May I, however, use the word also in other contexts not related to computer programming? May I use it e.g. as a shorter way to say "the period of time when Project XYZ is being implemented", as in:
During project runtime, the steering committee will meet at least biweekly.
Project runtime is from May 2017 to June 2018.
Or am I restricted to expressions such as
The project will be implemented between May 2017 and June 2018.
During project implementation, the steering committee will meet regularly, at least biweekly.
Other suggestions to express stuff like that elegantly are welcome.
Regaring "runtime": I looked it up in various dictionaires and text corpora, but so far I found it used only in the programming context. My desire to use it elsewhere may be rooted in my German background, as German Laufzeit can well be used for projects, cultural programmes, and funding programmes, too.
