Hi Kailash,
You have not stated the purpose of the suvey. The survey can be done, in major 2 ways, at the outset, depending on the required outcome.
If the purpose is to to use the survey data, for making long term policy then it is advised to go by Gallops theory. U will find it in the Social Research Methodology by Dr. P. V. Young.
If you need immediate sollution for a particular problem or imporovise upon the existing behaviour, in that case I would advice you to go OD way, i.e. by taking the survey through BARS and plan immediate interventions.
In cas you need further help just write to me at [Login to view]
