1) 4S dealerships must pay close attention to workflow management like customer development, needs analysis, and contract signing to ensure sales procedures are followed correctly. A competent sales supervisor is needed to train, motivate, and supervise each sales consultant. 2) Simply promoting the top salesperson to a supervisor role could result in bad management and loss of major salespeople. Other sales consultants may feel unfair and lose motivation or change brands. 3) To select a sales supervisor, the dealership should make the job duties clear, set transparent selection criteria, and assess candidates on both theory and practical skills in operating a team through a business competition. This process will identify the most competent leader while maintaining team morale.
