Hi @pratik before sharing the gyan, understand First, that Business Development is NOT Sales. Second, being into IT filed and presuming in B2B profile - the lead gestation period will be longer.
Start with the metrics and share this with your superiors - Reach -> Leads -> Sales (no. of clients) -> Revenue. So as your superior / management is aware that you are putting in all the efforts - although actual sales might take some more time.
As a pre-cursor to above step, create a story around IT solutions offered by your company. For each new prospects, tweaked the usage and highlight the benefits. You need to highlight - how the implementation of your IT solutions results in Reduce Cost / Increase Margin or Better Customer Satisfaction.
Sales would happen. finally for the corporate success and to become great salesman - Always Sell Yourself and the Service or Product.
