Long-term successful selling

Sales success has 3 causes and therefore also
3 assumptions

1
Harmony between personality and method of sale
The assumption in this case is self-knowledge. Only when you know your own strengths, weakness and limits, will you be able to consciously choose the correct sale methods and techniques.

2
Suiting the customer’s characteristic features provided this doesn’t compromise the authenticity of the salesman
In this case the assumption is understanding others. The "automatic" consequence of self-knowledge and understanding others is the optimization of social competence.

3
Specific knowledge of the product
The assumption in this case is knowledge of the product that puts the product features in touch with the individual motives and needs of the customer.
