I had a link inserted to Harvard Business School Publishing for reference which I now have removed. The page as it stands now should not be in conflict with Wikipedia policies.
No cohesion in some parts, especially when it comes to the example illustrated
SWOT analysis is a good tool by itself, BSC is another good tool combining both does not creat a better idea but maybe a better mapping in some of the situations.
When using SWOT analysis no one is forced to place strength or weakness at the financial level or any other level.
Maybe the use would be a pre-anlaysis for creating BSC.
Still however a good idea..
