WHAT IS A FRAMEWORK?

– Models, tools or maps that provide a systematic, logical way of analyzing a problem

– Show cause and effect relationships to focus on– Distill a complex, ambiguous problem to the relevant issues

– Guides intelligent questioning of the interviewer– Lays out your analysis in a logical, coherent manner—paints a

picture of how you think– Allows you to apply your experience to an unfamiliar situation

– SWOT analyses– Familiar frameworks—5 forces, 7 Cs, 7 Ss, 4 Ps– Matrices—2x2, more sophisticated multi-dimensional– Value chain analysis– Comparative economics– Product/technology life cycle– Decision trees
