Hi Sophie,

The key areas you will have to cover to prepare a panel/written case are the following.

1. Learn how to define a plan of action and stick to that

The first thing you should do in a written case is to define a plan and allocate your time in the best possible way.

Assuming 60 minutes for the analysis, a good approach would include:

• Initial quick reading – 10-20 min (this may depend on the amount of material)
• Structure the approach – 5 min
• Make slides/answer to the questions adding detailed analysis and math – 25-35 min
• Final review – 10 min

You should practice to stick to the time allocated to maximize your final performance.

2. Practice graph interpretation

You will probably have to analyze graphs as part of the data provided. The best way to practice is to take graphs from online sources and use a timer to test in how much time you can understand the key message. McKinsey PST graphs are good practice for that.

3. Work on quick reading and quick understanding of key information

You won’t have time to read and prioritize everything, therefore you have to understand where to focus. The ideal way to practice is to use long cases such as HBS ones. You should then learn to absorb the key information of the case. Quick reading techniques could also help.

4. Practice quick math

You will probably have some math to do as part of the data analysis. GMAT and McKinsey PST math should work well to prepare for this.

5. Learn how to communicate your slides/answers

When you have to present your findings in the second part, I would suggest the same structure used for a conclusion in a live interview, that is:

1. Summarize the main questions you have to answer
2. Present your proposed answer and detail the motivation behind
3. Propose next steps for the areas you have not covered

As you will not be able to double-check hypotheses with the interviewer while you prepare the presentation, you should clearly state when you are making hypotheses and that you will have to verify them with further analysis.

When you have to prepare slides I would also recommend to work on:

A) Structure the order of the slides

Normally the structure for a 5-slide presentation is the following:

• First slide summarizes the question and provides the answer
• Second, third and fourth slide have the supporting arguments for the first slide
• Fifth slide has the next steps

B) Structure the content of each slide

There are three basic components for slides:

1. Title
2. Chart or data
3. Label for chart

Many people structure the title as the mere description of what the chart is about.

A great title instead shows the implication of the graph as well.

Example: say the graph is showing a cost structure for a division.

• A bad title would be: Cost structure from 2005 to 2015.
• A good title would be: Cost structure of Division XYZ is not sustainable”.
• A great title would be Cost structure of Division XYZ is not sustainable due to ABC, assuming you have insides on the cause.

The rule of thumb for the title is that if you read all the titles of the slides together you should get a clear idea of what is going on.

C) Present the slides

When you present, I would suggest the following steps for each slide:

1. Introduce the slide: “Let’s move to slide 2, which will show us why we have an issue with this division”
2. Present the main message of the slide: “As you can see, we have a cost structure which makes unfeasible to be competitive in this market”
3. Provide details: “The graph, indeed, shows how our fix cost is XYZ, while competitors can benefit from economies of scale. Indeed…”

In terms of how to prepare, I do a session exactly on that.

Before the session, I can send you the data source to work on. We can then simulate the panel during the class, reviewing step-by-step all the improvements needed.

Please feel free to send me a message in case you have any questions.

Best,

Francesco
