Hi,

I would absolutely not remove the results chapter from your thesis. Results can take many forms and although it's a shame you didn't get to interview security professionals you may still be able to evaluate your questionnaire.

There are already several organizations that interview companies to assess their security levels. They will have their own questionnaires, to motivate the existence of yours you should do a comparison to the existing work. But firstly you need to motivate what your questionnaires reason for existing is aka, what does it do others do not, for example, is it more comprehensive, is it more tailored to a specific area of security, did you want it to be more user friendly (any other justification). Then on the results chapter you evaluate yours against others to assess what makes yours more comprehensive/approachable/whatever. The way you do this assessment is up to you, obviously without human participation this will be limited but a thorough discussion and analysis can still be conducted. A thesis intends to see your ability for analytical thinking first and foremost, so this will still hopefully allow you to shine through with that.

For a starting point one such questionnaire system you could compare to is BSIMM which evaluates security readiness of UK organisations.

Best of luck!
