Hello Folks,
IBM certifications generally relate to job roles. The 486 exam is just one part of the job role of Certified Enterprise Developer. For this particular role, IBM identifies four tests as the core requirements:
Test 310, Test 486, Test 484 and Test 287. Although I consider myself capable of doing OOAD with UML, I do not stress that as a qualification. Rather, I state my abilities as an IBM CED, among other credentials. Anyways, that's my two cents worth.
