Thank you very much for your participation. We try to cover all aspects of agile software development like "TDD", "short release" etc. as describe in the literature. This is the reasons why the questionnaire is so long. Whether those belongs to agility or not we hope to find out during the analysis.

We assume that CMM tool only provide the technical basis for a good documentation but how well it is used depends on the developer.

Thank you again for your participation!

This comment exemplifies an important potential source of bias in your future analysis: judging how well practices are applied, which is neither objective, feasible, or relevant. Someone's use of a practice shouldn't be considered more (or less) agile on the basis of their success, and you also lack clear measures of success to begin with.
