Who collects requirement from customer? Do they have development experience

A senior manager with development expertise talks to the customer to understand their requirements. Prime Soft Technology advises: Obtaining the correct requirements from the customer is absolutely crucial to the success of any project. Whilst the best salesperson may be trained to do this, our experience is that using a person with development expertise makes this process more reliable and far quicker, because it eliminates communication errors. Of course, the development expert must have the business and communication skills to build a rapport with the customer.
