We are sending this survey to a wide range of respondents.
In order to easily get a big picture view, the questions are mostly closed-response type questions (e.g. multiple choice). There is often the opportunity for a comment after the question, and there is an open-response question at the end of the survey where you can note down any important issues that you would like to share with us, and that haven't yet been covered.
The survey shouldn't take longer than 10 minutes to complete. Thank you for your time and considered responses, in advance!
