The ISM was then drawn up to show factors affecting the intent to buy an original brand soccer ball. The study&rsquo;s population consisted of the country&rsquo;s sports management professors as samples and eight experts were chosen in a targeted manner. The MATLAB2014 software was used for the implementation of the ISM.<br> <strong>Results. </strong>The findings were shown in diagrams with five levels. The factor &lsquo;ball appearance&rsquo; was at the fifth level, the factors &lsquo;brand name&rsquo; and &lsquo;country of manufacturer of brand&rsquo; was at the fourth level, &lsquo;congruence of price and quality&rsquo; was at the third level, four factors of &lsquo;brand identity&rsquo;, &lsquo;brand image&rsquo;, &lsquo;perceived value&rsquo;, and &lsquo;brand store sales&rsquo; were at the second level, and &lsquo;intention to buy&rsquo; was at the first level.<br> <strong>Conclusion. </strong>An original brand soccer ball should be beautiful and have an attractive design. It must have a proper shape and it must create a unique identity so that the positive image of the product is accepted by customers. It must create value for customers when they weigh two aspects: What they have paid for it and what they have received.</span></span></div> Ball Appearance, Brand Name, Country of Manufacturer, Congruence of Price and Quality, Brand Identity, Brand Image, Perceived Value, Brand Store Sales, Intention to Buy 85 91 http://aassjournal.com/browse.php?a_code=A-11-681-1&slc_lang=en&sid=1 Hasan Gholami Ghajari hassangolami17@yahoo.com 10031947532846004773 10031947532846004773 No Department of Sport Management, Faculty of Physical Education and Sport Science, University of Mazandaran, Babolsar, Iran.
