The model is a strong tool form competitive analysis at industry level
It provides useful input for performing a SWOT analysis
Disadvantages
inside-out strategy is ignored (core competence)
it doesn't cope with synergies and inter-dependencies within the portfolio of large corporations (parenting advantage)
the environments which are characterised by rapid, systematic and radical change require more flexible, dynamic or emergent approaches to strategy formulation (disruptive innovation)
sometimes it may be possible to create completely new markets instead of selecting from existing ones (blue ocean strategy)
