Gyan for MBA students before you join ur summer internship organizations ..

Obviosy 4Ps, 3Cs and other models will help u to have a structured approch ... but for any marketer the most important thing is to feel the market by understanding the grassroot realities ... i.e. the consumer behavior .. i mean qualitative research

The normal process is in this order ...
1. start with secondary research ... googling
2. Focused group discussion (FGD)
3. Qualitative and qualtitative research ... to get some stats
4. validate the research
5. Design Marketing Strategy/ key insights

One important thing is that sometimes researches fail ... and common sense works

The best marketer is one who is fully involved in the product/ brand !!!
