A strategy map is a diagram that describes how an organisation creates value by connecting strategic objectives in explicit cause-and-effect relationships.
Strategy maps can be produced at organisational, departmental and even project level. They provide an excellent snapshot of strategy and are supported by measurable objectives and initiatives.

Strategy maps enable organisations to:
clarify strategies and communicate them to employees
identify the key internal processes which drive success
align investments in people, technology and organisational capital for maximum impact
expose gaps in strategies so that early corrective action can be taken
There are five main principles behind strategy maps:
strategy balances contradictory forces
strategy is based on a differentiated customer value proposition
value is created through internal business processes
strategy consists of simultaneous complementary themes
strategic alignment determines the value of intangible assets
The strategy map (Kaplan and Norton) evolved from the four perspective model of the balanced scorecard, adding a visual dimension which improves clarity and focus.
