Thesis Research Proposal- Corrections!

Hello everybody,
I constructed my thesis research proposal on management related topic where I’ll be analysing the impact of new technologies and social networking on the customer’s relationship in hotel industries. But it needs to be corrected and I am in a desperate need for help!

I have studied the background on the related topics.

I have analysed the methods adopted by other researchers

From the previous researches, I have estimated that technologies and social networking can strongly influence the CRM in hotel industries and they can be used to boost its growth

The teachers who read my proposal said that the topic was below the standards of a PhD course. It lacked the critical analysis and a lot of studies have already analysed the impact of these two variables in the hotel industry. They asked me to present a better argument. Any advice on the matter would be sincerely appreciated. Thank You!
