How can I get some statistics on the amount companies spend on monitoring or diagnosing equipment/structures for failure?
I am trying to do a marketing and research task on how much companies spend on monitoring equipment, fault diagnosis etc, what softwares or technologies those companies use, how often they use them etc. The report should have some real examples as well, so I should probably contact several companies and ask for such data.
Questions:
Where should I start? I am totally lost and don't how to get such estimates.
Is there anyone you know whom I can contact to get these statistics (I don't mind signing NDA)?
Are there any other places or communities where I better ask this question?
Sorry if this is the wrong forum to ask these questions.
