Third, the developed empirical causality analysis procedure is holistically integrated in the strategic planning process to comprehensively support an analytical-rational decision-making style. Altogether, this book offers crucial scientifi c as well as practical insights on the improvement of strategic planning execution by the application of empirical causality analyses.
