It Must Be Objective Driven<\/h2>\n\n\n\n<p>Your structure must directly answer the <strong>client\u2019s objective<\/strong>.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<p>Objective: Increase Profit<\/p>\n\n\n\n<p>Profit<br>\u251c\u2500\u2500 Revenue<br>\u2514\u2500\u2500 Costs<\/p>\n\n\n\n<p>Every branch must connect directly to the goal.<\/p>\n\n\n\n<p>This is the foundation of <strong>how to structure profitability cases<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. It Must Follow the MECE Framework<\/h2>\n\n\n\n<p>The <strong>MECE framework consulting approach<\/strong> ensures:<\/p>\n\n\n\n<ul>\n<li>No overlap between branches<\/li>\n\n\n\n<li>No important driver missing<\/li>\n<\/ul>\n\n\n\n<p>Example:<\/p>\n\n\n\n<p>Revenue<br>\u251c\u2500\u2500 Price<br>\u2514\u2500\u2500 Volume<\/p>\n\n\n\n<p>Price and volume do not overlap.

It Must Be Customized<\/h2>\n\n\n\n<p>Avoid blindly applying <strong>generic consulting interview frameworks<\/strong>.<\/p>\n\n\n\n<p>If profits are declining in one region, include <strong>regional
