othesisdriven and end productsoriented(基于假設(shè)和最后結(jié)果導(dǎo)向) “Porpoise” frequently between hypothesis and data( 經(jīng)常竄梭于假說和數(shù)據(jù)之間) Keep the analyses as simple as you can. Be suspicious of huge linear programs and their ilk. (保持分析近可能的簡單。 do not expect every piece of data to be available ?Organize your thoughts and structure the problem ?Pick one branch to probe, develop hypotheses, ask for a few relevant facts, defend/refine hypotheses based on new information, probe further, and describe implications you see ?Pick another branch and continue (Make sure you are prioritizing your responses) ?Put it all together: try to answer the overall question (big picture) with a reasonable, actionable conclusion –Review what you know –Clarify what you do not understand –Solidify and tender remendation What not to do ?Play 20 questions ?Assume 1 framework fits all ?Cover 1 issue without mentioning and prioritizing all key issues ?Dig your heels in ?Hide from the details (or the numbers) ?Get frustrated ?Conduct a postmortem in the interview 6 FIVE EASY STEPS TO BULLETPROOF PROBLEM SOLVING Step 1 State the problem Step 2 Disaggregate the issues Step 3 Eliminate all nonkey issues Step 4 Conduct critical analyses, porpoise between data and hypotheses Step 5 Synthesize findings and build argument ? 7 Clear statement of problem to be solved or issue to be resolved斷定 STEP 1: STATE THE PROBLEMLEM Characteristics of a good problem statement A leading question or firm hypothesis( 對(duì)答案有誘導(dǎo)性的提問或穩(wěn)固的假說) Specific not general( 詳細(xì)和精確的非概括性的綜合的) Not a statement of fact or nondisputable assertion( 不是事實(shí)的陳述或武斷:沒有討論余地的斷言) Actionable( 可控告的) Focuses on what the decision maker needs to move forward( 關(guān)注于什么是決策者需要前進(jìn)的) ? Interviewer states the problem Problem has been clearly stated, and you understand it Problem has NOT been clearly stated, or you don?t understand it You must clearly understand the problem Paraphrase the problem to make sure you have it right Ask questions to clarify the issue Step 2. You are responsible for ensuring the clarity of the problem 8 STEP 2: DISAGGREGATE THE ISSUES Why use logic trees? 1. To break a p
