MSOCS, the whole point of such management surveys is to confine your choice of answers and to avoid having to report the difficult stuff up the chain of command. The companies that compile them are very specific in their questions to their clients so that they they compile the survey accordingly.
An online survey yields nice, neat, numerical results that can then be "analysed" to produce "statistics". Airships and politicians then get pie graphs and useful figures to spout in parliament.
Perhaps even more relevant are a) online surveys are relatively cheap and b) they don't get bogged down in individual issues - even if they are issues common to many of the respondents.
