This is a permutation problem.  There are 15 different possibilities for the president.  Once the president is selected, there are now only 14 different possibilities for vice-president.  And once the vice-president is selected, there are only 13 different possibilities for the secretary-treasurer.  So it is:

15 * 14 * 13 = 2730
