It can be seen in Table I that Octave and COBIT
frameworks are applied at a strategic level while IS027001/2,
ITlL and ISF are applied at a tactical level. In fmding a good
approach, a combination of "what" and "how" as well as a
combination of applicability levels (i.e. strategic, tactical and
operational) should be aimed for. These principles form the
selected frameworks, are also used to guide the ITSRB
approach's principles.
