To overcome this, companies can develop and analyze their sales pipeline. When leaders track the volume of leads coming into their funnel, the number that are qualified buyers, the percentage that make it to the proposal stage, and more, they gather valuable insights into where there are areas for improvement in their sales process. This can help them strategically grow their overall sales. In fact, managers can use their pipeline to develop a more disciplined and structured approach to sales, making it easier to determine larger business needs (such as hiring) and goals (such as revenue and cash flow). 
In brief, we are inclined to go along with someone’s suggestion if we think that person is a credible expert (authority), if we regard him or her as a trusted friend (liking), if we feel we owe them one (reciprocity), or if doing so will be consistent with our beliefs or prior commitments (consistency). We are also inclined to make choices that we think are popular (consensus [social proof]), and that will net us a scarce commodity (scarcity).
