How to Write a Case Study: The Underrated Power of Storytelling

Stories are as old as time. Some entertain, others inform, and in the business world, they’re an excellent way to engage customers and promote your brand.

If you’re selling a product or service, your prospective customers want to know how it will improve their lives. It’s all well and good to say, “Buy X to get better Y”, but when consumers are bombarded with between 4,000 and 10,000 marketing messages every single day, it’s natural for them to be sceptical. That’s why storytelling through a business case study is so powerful. It allows you to cut through the noise and demonstrate your product or service in action.

It’s also a great opportunity for you to get creative and show off what makes your brand unique – without being too salesy. When you do it right, case studies help build trust and legitimacy with potential customers. In this article, we’ll discuss how to write a case study, what to include in a case study, and how to use the power of storytelling to attract more customers.

Storytelling

What is the main purpose of a case study?

The main purpose of a business case study is to tell the story of how your product or service has solved a customer’s problem. It should provide enough detail so that other customers have confidence that they can solve their own problems by using your product or service. Case studies are a way for you to demonstrate the true power and potential of your offering. It’s something that’s often far more convincing than a sales pitch.

What to include in a case study

In contrast to a testimonial, which is usually just one short paragraph of praise or thanks, a professional case study is typically more detailed and provides a much fuller picture. Here are some of the key elements of a B2B case study:

  • Background information on the customer’s problem.
  • Details about how they used your product/ service/ solution.
  • Results achieved (e.g., improved performance, increased sales, etc.).
  • Quotes from key stakeholders involved in the project.
  • A conclusion that demonstrates how your offering has provided a solution to their problem.

Why is storytelling in a business case study important?

Ever sat by a campfire and got lost in a great story? There’s a reason for that. When we tell them well, stories tap into our emotions and allow us to imagine ourselves in another person’s shoes.

In the business world, using storytelling in your case studies has the same effect. It allows the reader to imagine themselves as the main character of the story (the business). Did you help a business multiply its sales figures x5? Boost lead generation x20? When you do it right, the case study helps the reader (your prospective customer) imagine themselves experiencing the same benefits. In more detail, here’s how creating a case study that tells a story is so powerful:

Emotional connection

At the core of storytelling is the ability to create an emotional bond between the reader and the content. Humans are naturally drawn to stories because they evoke feelings – whether it’s happiness, sadness, excitement, or inspiration. A business case study that incorporates storytelling taps into these emotions.

For instance, a simple statistic such as “Product X increased sales by 30%” can be informative. However, presenting it within the story of a small business owner who was on the brink of shutting down and then turned things around dramatically using Product X is far more compelling.

Greater credibility

According to a study by Edelman, brand trust is a dealbreaker for 81% of consumers. But trust in traditional advertising is at an all-time low, with 79% of British consumers and 83% of American consumers agreeing with the statement, “In recent years, it has become harder to trust what companies say and do”. This means brands must go beyond traditional advertising to build trust with their customers.

One way of doing this is by including customer stories in case studies that demonstrate how your product or service can help solve a real-world problem. They can add extra credibility, and research shows that people trust advertising that talks about values more than products. A professional case study is the perfect opportunity to do this, by focusing on the customer’s journey and shared values, rather than just listing features and benefits.

Stories stick

A study by Stanford professor Jennifer Aaker found that stories are remembered up to 22 times more than facts alone. This isn’t to say that data isn’t important, but it becomes far more memorable when wrapped in a story. For businesses, this means that a potential customer is more likely to remember your brand and product if they’ve read an engaging case study about it.

Real-world proof

While hearing that a product is good can be persuasive, seeing it in action is even more so. A Nielsen study reported that 92% of consumers trust peer recommendations over all other forms of advertising. By showcasing real-world examples of satisfied customers who benefited from your product or service, you’re providing the most trusted form of endorsement.

How to write a good case study using storytelling

So, you’ve chosen a customer to feature in your case study. Now you need to think about how to turn their story into an engaging piece that doesn’t bore your audience. Here are a few tips to help you turn your case study into an engaging story of triumph over adversity.

How To Write A Case Study - The Hero's Journey

Understand the hero’s journey

At its core, every story follows a structure – and one of the most universally recognised is “the hero’s journey.” Coined by Joseph Campbell, this narrative arc presents a hero who undergoes a transformative adventure. In the context of case study writing, this hero isn’t your brand – it’s your customer.

1. The call to adventure. This is the point where your customer realises they have a problem that needs solving.

Example: A business struggles with low website traffic and subpar conversions.

2. The challenge. As they attempt to address the issue, they face hurdles. This is where they might try out various solutions without success.

Example: The business tries different marketing tactics but doesn’t see significant improvement.

3. Assistance or guidance. Enter your brand – not as the main character but as a mentor or guide. You offer a solution to their problem.

Example: The business discovers your content marketing services with an emphasis on SEO and conversion copywriting.

4. The transformation. With your product/ service/ expertise, the customer tackles their problem head-on and emerges successful.

Example: By leveraging your tailored services, the company establishes a sound marketing strategy that leads to more targeted web traffic, higher conversions, and increased sales.

Long Empty Road

Prioritise authenticity

When deciding how to write a case study or what to include in it, keep authenticity at the forefront. Potential customers can tell when a story feels forced or fabricated. Using real scenarios, genuine customer feedback and quotes, while showcasing both challenges and successes will make your narrative more relatable.

Position your brand as the guide

Remember: in the business case study, your brand is not the hero. It’s the customer’s journey we’re interested in. Your product or service is the tool or mentor that helps them on their quest. This approach allows potential customers to see themselves in the story and understand how your offerings can help them in their own journey.

Use real data to enhance the story

While storytelling is crucial when creating a case study, integrating real, tangible data provides evidence to back up your narrative. Whether it’s how a customer increased their revenue, improved efficiency, or achieved any other key metric, these numbers validate your story and offer prospective clients a clear vision of potential outcomes.

Conclusion is key: Tie it all together

End your case study by reinforcing the transformation your customer experienced. This not only emphasises the value of your product or service but also brings the story full circle. It resonates with the hero’s journey arc. You can also add some details about future plans. This reinforces the idea that there’s still more room for growth and success with your products or services.
