Here are some popular case repositories:
- Harvard Business School
- Ivey Cases
- Case Center (formerly European Case Clearing House)
- INSEAD cases
- Darden Cases (UVA)
- Kellogg Case Library
Here are some popular case repositories:We often talk about culture as a source of sustained competitive advantage (see Jay Barney’s article on the topic).
I have run a great exercise where I send students on an artifact hunt through the business school to identify strengths and weaknesses in the school culture. Students present and analyze their artifacts and we discuss the implications for the competitiveness of the school. The next class explores the levers or impact points one would use to influence the culture. A final class might explore the implications of this for managing strategic change. The time this takes may make it better for a strategy elective but I am using it in my core class this semester.
Here is a bit more detail on how the exercise is run:
over most brick and mortar rivals that its customers need not pay sales tax. That is now ending in some states as they agree to collect the taxes (notably California). So how are they responding? They are building more warehouses so that, in some metropolitan areas, they will eventually have same-day delivery. Ironically, with each day, they have become more of a brick and mortar operation. Still, that will give them an advantage over ecommerce rivals. It also requires substantial investments in distribution that rivals will have a hard time duplicating.
We often spend time focused on what makes a strategy inimitable. Of course, the spate of recent law suits tells the other side of the story in terms of the risks of copying. That said, there is little new under the stars and imitation can yield tremendous returns. We don’t see much focus in cases (or the literature) on imitation as a capability. What makes firms good at it?

Here are a series of news articles that one can distribute (not all are really needed). In order to assess Google’s prospects for creating value, one must evaluate the following key sources of uncertainty:
The essence of this exercise is simple. Teams must build a device that will catch an egg dropped from 25 feet (e.g., a stairwell). The trick is that they must build it from items purchased in an auction. As such, items that are easy to use (e.g., an old pillow) are very expensive while items that are hard to imagine a use for (a brick) are cheap. Profit is determined by 1) succeeding in the task of catching an egg and 2) having the lowest cost function. As such, this demonstrates Barney’s (1986) notion of superior expectations in strategic factor markets.
Now that you see where this is going, here are the rest of the details.

Requires two 25-piece puzzles. Prior to the exercise, two pieces from each puzzle should be blacked-out with an indelible marker. Additionally, one of the fifty pieces should be placed in the trainer’s pocket prior to the training. Continue reading
This video shows the world record in cup stacking. The task requires speed in a repetetive task. It might be thought of as a capability however, it is clear that it is not about flexibility or adaptability. This helps to illustrate the distinction of a dynamic capability — this is not strategy under uncertainty.
A bit of trivia is that Emily is the CEO’s daughter for SpeedStacks, the company that makes specialized cups for stacking and the primary backer of the “World Sport Stacking Association.” She might actually be a resource for her father’s company…

This video shows a play one could never plan. Might it be possible to train a team to improvise when the opportunity presented?

The Tinkertoy exercise is simple but exposes students to a variety of issues linked to formulating and implementing strategy. This deeper application of the common ice breaker has been published by Coff & Hatfield (2003) in JSME (Click here for full text). There are a number of slight modifications that make the exercise very valuable for different topics in a strategy course. For example:

The exercise can demonstrate key features of the resource based perspective and first mover advantage by having the teams execute in waves and watch how much imitation occurs (often team stick to their planned strategy even if they watch another team fail using that plan).
Jay Barney describes how he teaches Strategic Management for Executive Education, giving examples of Walmart, Southwest Airlines and their success in very tough industries.
I’ve been using simulations to tie together segments in my class and to give students a better experience with the process of strategy. It is important to allocate a good chunk of time — from one to three hours — to fully debrief the sim. This debrief includes some sharing of emotions, since simulations can result in conflict and anxiety — I’ve had teams explode and almost come to blows. It is useful to point out to participants that although this is a simulation, part of the results are a reflection of the individual themselves, along with their particular role, and the context provided by the simulation. Three readings that may be helpful regarding sims are (Also see Brian Boyd’s website for additional resources below under OTHER TOOLS & LINKS:
