3 HYPOTHESIS Hypothesis is an assumption based on some reasons or observation. Profit declining Decrease d revenue Increase d cost Hypothesis Hypothesis 02/27/2020 4

HYPOTHESIS Why we need hypothesis Many issues can be the reason to a case. It takes enormous of time to analyze everything. In a case interview, you usually only have 30 to 40 minutes to finish it. So Hypothesis driven case solving skills saves you time by at least eliminating the wrong directions. 02/27/2020 5 Case interview secretes, by HYPOTHESIS How to use hypothesis eliminate wrong directions In a business case, maybe the declining profit is caused by a decreased revenue, or an increased cost. To analyze this problem, Ill make my hypothesis that the decreased revenue is the main reason, and look for information about the revenue of my client. If I find the revenue doesnt change, Ill then switch to the cost side. By

then, Ill have to change my hypothesis as an increasing cost eats the profit. Profit declinin g Decreas ed revenue Increase d cost X ? ? 02/27/2020 6 Case interview secretes, by

HYPOTHESIS When to state your hypothesis As early as possible? After several background questions? I suggest to state it after several background questions, so that the hypothesis can be based on some specific facts. Remember, your analysis is all based on your hypothesis. So dont forget to state a hypothesis. 02/27/2020 7 MEETING AGENDA Skills for today Case solving skills Hypothesis Review of the frameworks: Profitability

Mutually exclusive, collectively exhaustive. Sometimes a little overlap is allowed Example: customer segments: according to age, yes! According to income, yes! According to hobby, no Conclusive. By analyzing this issue tree, one can consolidate a

conclusion Example: Pricing: lower than all the substitute product, yes! Lower than one substitute product, no 02/27/2020 10 ISSUE TREE How to form a good issue tree: 1, state your hypothesis 2, based on your hypothesis, form your issue tree 3, you can embed some frameworks into your issue tree, or embed frameworks into a framework, or embed your sub-issue tree into a framework. 4, check is it MECE, is it conclusive? Communicate your issue tree to interviewer: To introduce every branch before delve into one.

The CEO of the gum manufacturing company is concerned because his company is experiencing declining margin. My questions to you are: 1, the reasons behind declining profitability; 2, your suggestions for improving profitability. 02/27/2020

14 Wharton Consulting Casebook 2007- SAMPLE CASE Hypothesis: This is a profitability problem, the company needs to improve their revenue. Issue tree: typical profitability structure Revenue Price per unit The number of unit sold Cost Fixed cost Variable cost 02/27/2020 15 DRILL DOWN Tip #1: Start with the branch that eliminates the most uncertainty

first. Start with the most relevant, critical information. X Revenue Price per unit-----------------------------------No info The number of unit sold---------------------Has been increased Cost Fixed cost----------------------------------------No info Variable cost------------------------------------Components of Restate the hypothesis: This is a profitability problem, the company needs 02/27/2020 16 DRILL DOWN Tip #2: Use both quantitative and qualitative analyses. Always try to

quantify a problem; Feel free to ask why and how in addition to what; Variable cost: Components of the cost: Cost of goods sold (COGS): ------------------------------------------No change gum, sugar, flavor, smell, color Labor-----------------------------------------------------------------------No info Selling, General and Administrative expenses (SG&A)------------No info 02/27/2020 17 DRILL DOWN Variable cost: Two types of products: flavored and flavorless gum Both products are sold at the same price point Composition products:

Flavored gum: gum, sugar, color dye, and flavor Flavorless gum: gum, sugar, color dye Note that the gum, sugar and color day raw materials are same in size for each of the two products. 02/27/2020 18 DRILL DOWN Tip #3: Dont stop drilling down until you reach a conclusion. Either drill down until you find it supports your hypothesis or you find it disproves your hypothesis. Then move to the next item in your issue tree. Never propose a solution until youve isolated and defined the problem. Revenue Price per unit-----------------------------------No info The number of unit sold---------------------Has been increased Cost

Fixed cost----------------------------------------No info 02/27/2020 ? 19 DRILL DOWN Tip #3: Dont stop drilling down until you reach a conclusion. Either drill down until you find it supports your hypothesis or you find it disproves your hypothesis. Then move to the next item in your issue tree.

Revenue Price per unit-----------------------------------No info The number of unit sold---------------------Has been increased Profit Cost Fixed cost------------------------------------No info

02/27/2020 20 DRILL DOWN Tip #4: When to stop analyzingthe minimally necessary data. Dont over analyze this branch, which makes your case solving inefficient. Variable cost: Two types of products are sold at the same price point Composition products: Flavored gum: gum, sugar, color dye, and flavor Flavorless gum: gum, sugar, color dye Note that the gum, sugar and color day raw materials are same in size for each of the two products. 02/27/2020 Conclusion for problem1: Because the increasing sales of the flavored gum, the profit margin declined despite of an increasing

gums. See a declined margin; Because of selling more flavored gums; Flavored gums have lower margins. Increase the margin for flavored gums. 02/27/2020 23 SYNTHESIS More comprehensive ones: Final recommendation. Increase the margin for flavored

gums. Support info 1; Flavored gums have lower margins; Support info 2; See a declined margin is caused by Imperfection of the analysis and next step works; Reiterate the final recommendation. selling more flavored gums; Based on given information. Maybe adjust the margin for unflavored also Increase the margin for flavored

gums. 02/27/2020 24 SYNTHESIS When to synthesize: Do mini synthesis when switching gears to another branch As we can see from above analysis, the declined margin is at least partially caused by the increased revenue. Another possibility is the decreased profit, and I would like look at the profit part.
