The sales manage need to think in terms of commitment and at the same time be able to comprehend and document the processes and workflow (i.e., supply chain and value chain) of the customer during his sales visits. Salesmanship is about relationship management, i.e., relationship with internal and external customers, suppliers, contractors, agencies, etc.-relationship brings us into politics. The sales manager needs to have situational awareness and be sensitive to the cultural factors present during the sales cycle. Salesmanship is about leadership, i.e., the capacity to translate vision into reality. The sales manager is motivated and guided by principles, i.e., he is a soldier and a gentlemen.
