Research questions from the literature

I'm pleased, and slightly surprised to find that my initial questions, months ago, have developed into something researchable. I had thought those initial questions were researchable but perhaps they weren't and anyhow, I had a less clear idea of how I'd research them than I do now. From the literature I have evidence that both accountability and relationships are discursive constructions, which means that research needs a constructionist perspective, a qualitative approach to data collection and either grounded analysis or discourse analysis. I think the questions are:

• To what extent do public sector managers account for their use of consultants?
• What do different public sector managers do to demonstrate their accountability for managing consultants?
• To what extent does the kind of client-consultant relationship, influence the expression of accountability in a public sector organisation?
• Are there gaps in public accountability?

It's the third one that is researchable and most interests me.
