Questions are a vital weapon in a sales person’s arsenal.  They help establish the needs of the customer and uncover further information that can be used not only to close today’s sale but future sales as well.  Questions help establish a report and make the customer feel at ease.  It is the ability to dig deep and discover a customer’s hidden needs and desires that separate good sales people from great.  With this in mind I want to take a minute and go over some of the basics of questions.
There are essentially two essential types of questions that are ever asked: Open ended and closed ended.
Opened ended questions are designed to put the buyer at ease and get them to open up and be perceptive of your product. You want them to tell you about themselves, their company, and their needs.  When used properly not only will a customer give you all the information you need to emotionally attach them to your product but they will supply you with the answers you need when handling their objections.  Using opened ended questions shows them your interest in helping them or their company.  It establishes trust in the business relationship. 
Examples of opened ended questions are:
Tell me what you’re looking for in my product?
                Explain to me your companies needs?
                What would the perfect product or service do for you?
Closed ended questions are simple questions designed to be answered with one word, usually a “yes” or “no.”  Use these questions when trying to gain agreement with the customer. Only ask closed ended question you know the answer to and have the customer saying “yes” repeatedly.  The more the mind says “yes” the harder it is for it to say “no.”  You are not trying to trick a customer; you are simply getting them to agree with what they already told you they need.
Examples of closed ended questions are:
                Do you agree?
                Does that make sense?
                Do you have any more questions?
I realize that some of this is elementary; the truth is that far too many people in sales lose sight of what is important to their customer.  They jump right into what their product offers without even knowing if it will fill their customers’ needs.    By asking too few questions and talking nonstop about their product the sales professional can come off pushy and indifferent to the consumers wants.  
Potential customers want to buy from someone they can trust and believe cares about their needs and desires.  Great sales professionals ask their customers, prospects, and clients plenty of questions to fully determine their personal or companies buying needs.  The most effective way to present their product is as a solution to a customers objectives or goals.  Both of which can be discovered with a few well worded quality questions.  
Higher quality questions allow the sales professional to effectively discuss the features and benefits of their product or service and position it in a way that their prospect can relate to. It solidifies what they are offering as a legitimate solution.  That is all most clients or prospects are interested in.  In other words the question they ask themselves is “Will this solve my problem?”
How do you get better at questioning?  That is simple, practice.  Practice on friends and family or anyone you feel comfortable with.  Seek out those around you that are excelling and find out the type of questions they are asking.  Ask if you can shadow them on a sales call or sit in on a sales meeting.  You can get better at asking good quality questions by expanding your product knowledge and knowing how your product or service can fulfill a want, need, or desire. 
It might feel awkward at first but the more you practice the easier it will get.  The easier it gets the easier you will be able to position your company or product as the only solution to your prospects problem.
