Unlocking Business Experimentation: Key Considerations
Written on
Chapter 1: Understanding the Importance of Business Experiments
As business experimentation gains traction, it can still pose significant challenges. Equipping yourself with research-driven insights is crucial before embarking on these experiments.
In recent years, the popularity of business experiments has surged. Designers create prototypes quickly to gather feedback from potential customers, while healthcare leaders test new processes on a limited scale to evaluate their effectiveness. Similarly, business owners and executives conduct small-scale experiments, focusing on the most successful initiatives. This trend towards experimentation benefits companies by providing valuable data to enhance their operations and customer offerings. As Chip and Dan Heath highlight in their book "Decisive," experiments enable decision-makers to validate their instincts about products and services, fostering increased confidence in their choices.
However, despite the rise in experimentation, execution can be fraught with difficulties. Even well-structured experiments may suffer from avoidable mistakes during implementation, leading many businesses to miss out on the potential advantages. To help you prepare for successful experimentation, consider the following strategies:
Section 1.1: Formulating a Clear Question
In "Experimentation Works," Harvard Professor Stefan Thomke emphasizes that experiments should be employed when they provide the only practical means to address specific questions that lack clear answers. For experiments to yield insightful results, the questions posed must be precise and measurable. For instance, asking "How much does advertising our brand name on Google AdWords increase monthly sales?" is a well-defined query that allows for accurate measurement of digital ad effectiveness. Conversely, a broad question like "Is digital advertising worth the expenditure?" is challenging to quantify.
Section 1.2: Implementing Significant Interventions
To determine whether a new change impacts your outcomes, it's essential to implement a sufficiently substantial intervention. For example, if a small grocery store wishes to promote its local sourcing, it should start by using large labels prominently displayed on product packaging. If the labels are too small or placed inconspicuously, customers might not notice them, leading the store owner to mistakenly conclude that consumers are indifferent. By initially employing larger labels, the owner can assess whether customers value local sourcing. Should there be no observable effect, the store can abandon the idea; if the response is positive, they can refine the label design based on customer feedback.
Section 1.3: Choosing the Right Audience
Oliver Hauser from the University of Exeter and Michael Luca from Harvard Business School advise selecting a customer group that accurately reflects your target demographic. While it may be tempting to choose the most accessible group, such as online users, this can lead to misleading conclusions. For example, younger online shoppers may behave differently than older customers who prefer in-store shopping. Using the former group to inform strategies for physical stores could result in misguided decisions.
Chapter 2: Conducting Effective Experiments
In the video "How to run experiments in business - do's, don'ts and best practices," viewers learn valuable strategies for setting up successful business experiments.
Section 2.1: Employing Random Trials
For effective experimentation, it's beneficial to divide a large group of individuals with similar characteristics into two subgroups: a treatment group and a control group. Implement changes only within the treatment group while the control group continues with the original offer. Monitoring both groups closely will yield insightful comparisons. For example, you might test a new email marketing campaign by sending two variations (one with a new message and another with the previous message) to random recipients to identify any differences in engagement. As Thomke notes, if the treatment group performs statistically better than the control group, the results can be replicated.

Section 2.2: Planning and Adhering to Your Strategy
Before launching an experiment, draft a comprehensive plan. What metrics are most important to you? How many observations will you gather? What is the duration of the experiment? What variables will you analyze? Utilizing a simple tool like Google Sheets can help you track this data. Once the experiment is underway, refrain from making adjustments. Whether the results align with your expectations or not, it's essential to avoid altering the course of the study based on preliminary findings. Such practices can introduce bias and skew your insights, as highlighted by research from Harvard Business School academics.
In the realm of business, navigating product, marketing, and operational decisions amid uncertainty is a constant challenge. Well-designed experiments empower business owners and managers to mitigate that uncertainty by providing evidence-based insights. These experiments need not be complex; small businesses can glean valuable lessons from simpler tests utilizing their existing resources.
