Objective To benchmark the core/quasi-core MBA strategy courses across top-ranked business schools in theUnited States and Europe This report summarizes the main findings All schools are anonymized and referred to as School 1, 2, 3, , 20. The order was generatedrandomly.2

Methodology Collection and analysis of syllabi (2019-2020 academic year) from 20 top business schools aroundthe world 17 business schools in the United States and 3 business schools in Europe Information on content, faculty/staffing, pedagogy, and reading materials 19 1-hour interviews with faculty in charge of course to Corroborate/clarify syllabus information Obtain quantitative course information Understand context of course (positioning in MBA program, staffing, strengths andweaknesses) Understand pedagogical approach Analysis and grouping of data in the following areas Context Faculty/Staffing Content Pedagogy/Grading3

Main Findings Timing: the core strategy course is often a stand-alone course available in the 1st semester (80%) asthe content is useful for internship interviews Courses have either one of two structures: marathon (several weeks with short sessions) or sprints(few weeks with long sessions) It is common for senior faculty to teach the course and to continue teaching it for long periods of time Relative homogeneity in the topics covered but heterogeneity in how topics are covered Most schools (14 3) follow classic tradition and/or value-based strategy Focus on core theoretical concepts of competitive strategy (e.g. price/cost strategies,alignment, 5 forces, and alike) discussed verbally and through cases 3 of these schools have idiosyncrasies briefed in the report Other schools (3) adopt an economic-driven course Focus on game theory models of dynamic interaction (e.g. models of entry, price wars,and alike) or on formal economic models about competitive strategy (e.g. Hoteling modelof diversification) Most schools use a mix of case method and lectures4

Strategy courses can be “marathons” (extensive)or “sprints” (intensive)11

Context: other notes Most schools reported having experiences low student-evaluations in theirrecent past that led to a revamp in the course Revamps punctuate periods of long stability with no changes in facultyand modest changes in topics12

Summary of context Strategy is mostly taught as a core course in 1st semester, often concurrentlywith technical courses that do not use cases No reported overlap with other courses Two types of strategy courses: Sprints: long sessions in fewer weeks (most courses) Marathons: short sessions spread over many weeks13

FACULTY/STAFFING14

Staffing – More seniors, less juniors In all schools but one, there is at least one senior faculty member teaching thecore class In 10 schools, out of 19 interviewed, all teaching faculty are seniors Only 4 schools assign juniors automatically to core strategy Most schools place juniors in undergrad course, part-time MBA course or electiveOnly these 4 schools have a process to rotate faculty in and out of the core class Only 3 schools reported to have some form of course head across sectionstaught; most schools have only an informal coordination15

Staffing – other notes Often the faculty teaching the core class do so for a long time Schools reported having senior faculty teaching the same course for between 10and 14 years When juniors start teaching the course, schools eventually report having somementoring process, though often informally 8 out of 19 schools use teaching assistants Schools rarely report formal coordination across faculty teaching differentsections of the same course16

Instructors typically teach 2 sections at a time18Faculty load: annual sections x number of faculty teaching1416 Higher faculty leverageabove that line, lowerfaculty leverage belowthat line24Number of sections6810 12School 14School 19School 11School 5School 4 Tradeoff betweenteaching multiple timesfor the same course forshort period of time vs.teaching once for a longperiod of timeSchool 20AverageSchools2 and 10School 17School 6Schools3 and 18Schools 7, 8, 9,12, and 16School 130School 101712345Number of faculty6789

What we did Characterize courses in multiple dimensions: Overall framing: HBS classic (Porter, Ghemawat, Collis/Montgomery, Rivkin)Value-based strategy (Brandenburger/Stuart)Resource-based view (RBV) (Barney, Wernerfelt, Prahalad/Hamel)Economics (Spulber, Besanko, Cabral, Saloner)Behavioral strategy (Gavetti, Fang) Topic analysis: Coverage of topic per school (extensive margin)Time intensity per topic (intensive margin)Clustering/Grouping of schools based on topic coverage Quantitative and formal orientation: 21Use of numerical evidence to sustain case-discussionUse of formal models to explain concepts

Five frameworks are often used to teach strategy Classic Strategy Value-based strategy E.g.: Spulber, Besanko, Cabral, SalonerBehavioral strategy 22E.g.: Barney, Wernerfelt, Prahalad/HamelEconomics E.g.: Brandenburger/StuartResource-based view E.g.: Porter, Ghemawat, Collis/Montgomery, RivkinE.g.: Gavetti, Fang

Similarity of topics across strategy courses: highoverall Schools 9, 10, and 14 are the mostdissimilar for different reasons: School 9’s course is heavilyecon-based focused oncompetitive dynamics and gametheory School 10’s course is heavilyecon-based and a mix ofmicroeconomics/IO and strategy School 14’s course emphasizesstrategy design andimplementation Formal models about productdifferentiation, cost advantage, andcompetitive dynamics appear in afew schools where the faculty’sbackground is mostly economicsMeasure: pairwise Euclidean similarity comparing vectors of share of course time spent on each topic.29

Summary of Content Although there are not striking differences in topics coveredacross schools, there are important differences in depth Strategy is often a stand-alone, self-contained, course withoutclear connection with other MBA courses Most schools distribute time across topics relatively evenly, andthe average topic is covered by something between 1 and 2sessions for all but one school Schools vary in terms of their pace Sprint through topics x deepen topics Few schools go through formal models More are starting to emphasize quantitative debates (e.g. relianceon financial indicators)31

PEDAGOGY32

Traditional cases are most popular course materialPooled number of readings in syllabi (across 20 schools)Book Cases are notupgraded often.8Research Article 11Other/Undefined33Note Non-case materialsare upgraded moreoften48Specialized Media53Book chapter56 General Media165Case19703350Average caseyear: 2008100Number of pieces150200Average year ofnews articles:2012

Cases and news articles (case-like materials)constitute most of the teaching materialsConceptual material: No textbook is widely accepted Apart from Brandenburger (most popularbook), most books are textbooks in theeconomics of organizations (e.g.Besanko et al) Most popular source of conceptualmaterials is magazine articles (e.g. HBR,MIT Sloan) “What is strategy” by Porter is mostpopular article Increasing number of school-specificmaterial36

Grading and pedagogical tools vary across schools Large variation in what is graded On average, 5 evaluation formats (max 7, min 2) Large diversity of exam formats Case-based exams are seldom used. Combination of small vignettes and conceptualquestions in different formats (multiple choice, free response questions). On average, 24% of final grade is associated with groupwork (e.g. group projects, simulations) Only two schools do not have a team-work activity composing the final grade Majority of schools have some version of experiential learning Most common type of experiential learning: group projects Only 4 schools do not have a team project Six schools have simulation as pedagogical tool; five of these use it in the final grade On average, 8% of the sessions are not used for case-discussion or lectures (i.e. for simulations,exams, and presentations).38

Summary of Pedagogy Although case-led discussion is still the backbone of strategy classes,there are three relevant trends Schools rely either on HBS cases or, more recently, on own cases Schools are using news articles in addition to and instead of traditionalcases in discussion-led sessions Most schools are using other tools to teach strategy, especiallyexperiential learning to illustrate strategy design and implementation Few schools rely intensively on case-method teaching Often, schools complement cases with Lectures to cover concepts “Mini-cases” (newspaper articles) Almost no exam is entirely case-based Team activities and/or experiential learning are used in 70% of coursesand included in students’ grade39
