Sources of 2ndary research on testing industry?
Just wondering if anyone knew of any market research previously conducted on the testing industry. E.G. RE trends in spending on testing or different types of testing (my interest is particularly in technical/performance testing). Any information on test services purchasing behaviour etc...
The reason being I am about to engage in some market research of my own and wanted to avoid re-inventing the wheel if there is already a lot of similar stuff out there.
Much appreciate your help with this.
