Using Inversion as a Mental Model for Product Management

In the world of product management, the ability to think critically and anticipate potential problems is essential for success. One mental model that can greatly aid product managers in this regard is inversion. Inversion, a concept popularized by the German mathematician Carl Jacobi, involves thinking about a problem in reverse order or considering the opposite of what is desired. Inversion is a powerful technique that involves flipping a problem on its head and considering the opposite perspective. By envisioning the negative outcomes or obstacles that may arise, product managers can proactively address them and create more robust and successful products. Here's how you can use inversion as a mental model for product management.


First and foremost, inversion helps product managers identify potential risks and challenges early in the product development process. By asking the question, "What could go wrong?" and brainstorming worst-case scenarios, you can identify vulnerabilities and mitigate them before they become major issues. This proactive approach allows you to incorporate necessary safeguards and contingencies into your product strategy, minimizing the chances of failure.

Inversion also helps product managers prioritize features and functionalities. Instead of focusing solely on what the product should include, consider what it should not have. By eliminating unnecessary features, you can streamline the user experience and deliver a more focused and impactful product. Inversion forces you to critically evaluate the value and impact of each feature, ensuring that you prioritize those that truly align with your product's core objectives.

Furthermore, inversion encourages a customer-centric perspective. Instead of solely focusing on how the product can benefit users, consider the inverse question: "How can this product harm or inconvenience users?" By examining potential pain points and designing with empathy, you can create a product that addresses user needs and provides a seamless experience. This approach helps build trust and loyalty among your target audience.

Lastly, inversion fosters a culture of continuous improvement. By regularly asking, "What could go wrong?" and seeking feedback from users and stakeholders, you can uncover areas for improvement and iterate on your product. Inversion challenges the status quo and encourages a forward-thinking mindset that constantly strives for excellence.


To effectively use inversion as a mental model in product management:

  1. Define the problem backward: Instead of focusing solely on finding the optimal solution, start by clearly articulating the undesired outcomes. By understanding what you don't want, you can work backward to identify the root causes and develop strategies to address them effectively.
  2. Embrace the "prevention mindset": Rather than solely focusing on achieving success, think about how to prevent failure. Consider what could go wrong with your product, and then devise proactive measures to mitigate those risks. By anticipating potential issues, you can develop contingency plans and ensure a more robust product.
  3. Challenge assumptions: Inversion encourages you to question your assumptions and beliefs. Identify the assumptions you are making about your product, target audience, or market conditions. Then, flip them around and examine the opposite viewpoint. This exercise helps uncover blind spots and promotes a more comprehensive understanding of the situation.
  4. Seek feedback from critics: Instead of relying solely on positive feedback, actively seek input from critics and skeptics. Inversion prompts you to invite opposing perspectives and dissenting opinions. Embrace constructive criticism as an opportunity to refine your product and make it more resilient.
  5. Consider opportunity costs: When making decisions, don't just focus on what you stand to gain but also evaluate what you might lose. By considering the potential opportunity costs associated with different choices, you can prioritize effectively and allocate resources efficiently.
  6. Plan for the worst-case scenario: Inversion urges you to prepare for the worst outcomes. Identify worst-case scenarios, such as product failures or unforeseen market shifts, and devise strategies to mitigate their impact. By being prepared for adverse situations, you can minimize risks and respond more effectively when challenges arise.


Let's say you're a product manager working on a mobile apps that provides fitness tracking and workout plans. Your team has been focusing on developing features that enhance user engagement and motivation, such as social challenges and virtual rewards. However, you notice that user retention is still not as high as expected, and many users drop off after a short period.

To apply inversion, you would consider the opposite of what you desire – in this case, the opposite outcome would be users leaving the app. By examining this inverse perspective, you might identify potential issues and uncover new insights:

  1. Problem reframing: Instead of focusing solely on enhancing user engagement, reframe the problem to address user drop-off. Ask yourself, "What are the factors that might cause users to leave the app?"
  2. User feedback analysis: Seek feedback from users who have stopped using the app and understand their reasons for discontinuing. This feedback can provide valuable insights into the pain points or unmet needs that are causing user drop-off.
  3. Feature prioritization: Instead of solely prioritizing features that enhance engagement, prioritize features that address the identified pain points and reduce reasons for user drop-off. For example, if users stop using the app due to lack of personalization, prioritize implementing personalized workout plans or tailored recommendations.
  4. User onboarding and education: Instead of assuming users understand how to use the app and its value, focus on improving the onboarding experience and educating users about the benefits and features of the app. This can help set appropriate expectations and increase user retention.

By applying inversion, you shift your perspective from solely focusing on engagement to addressing the factors that cause user drop-off. This approach helps uncover potential issues, identify new solutions, and improve user retention, ultimately leading to a more successful product.

Remember, the specific application of inversion will vary depending on the context and the problem at hand. The key is to challenge assumptions, consider the opposite perspective, and use the insights gained to make informed decisions and improve your product management strategies.

Problem reframing

Inversion and problem reframing are closely related concepts that complement each other in problem-solving and decision-making processes. While inversion involves thinking about a problem in reverse order or considering the opposite of what is desired, problem reframing involves shifting the perspective and redefining the problem itself. Together, these approaches provide a comprehensive framework for tackling complex challenges.

Inversion encourages individuals to approach a problem from a different angle by reversing the perspective. By considering the opposite of what is desired or focusing on what needs to be avoided, inversion helps to uncover hidden insights, challenge assumptions, and reveal potential blind spots. It prompts individuals to think critically and question their initial assumptions, leading to a more comprehensive understanding of the problem and its potential solutions.

Problem reframing, on the other hand, involves looking at a problem from a fresh perspective by redefining its scope or framing. It encourages individuals to step back and consider alternative interpretations, goals, or constraints. By reframing the problem, new possibilities and creative solutions can emerge. It helps to break free from traditional thinking patterns and opens up avenues for innovative approaches.

Inversion and problem reframing work hand in hand to enhance problem-solving. Inversion prompts individuals to consider the opposite of what they want, which can trigger new ways of thinking. Problem reframing then takes those new perspectives and further expands the possibilities by redefining the problem and exploring alternative angles.

By combining inversion and problem reframing, product managers can gain a deeper understanding of the challenges they face and generate more creative and effective solutions. These approaches allow for a comprehensive analysis of the problem space and encourage a mindset of exploration, adaptability, and innovation. Together, they empower product managers to overcome cognitive biases, challenge assumptions, and unlock novel insights that may lead to breakthrough products and strategies.

Ultimately, inversion and problem reframing provide a powerful toolkit for product managers to approach problem-solving from different angles, break through mental barriers, and discover innovative solutions. By incorporating these techniques into their decision-making processes, product managers can navigate complex problems with greater clarity and creativity, leading to more successful outcomes.

The Slow Elevator Problem

The Slow Elevator Problem is a common issue that many people encounter in buildings where elevators take a significant amount of time to arrive and reach their destination floors. Let's apply problem reframing to address this challenge:

Problem statement: The elevators in a building are slow, causing inconvenience and frustration for occupants and visitors.

Reframed problem: Instead of solely focusing on the slow elevator speed, reframe the problem to explore broader solutions that improve the overall elevator experience. Ask yourself, "Is elevator really slow or its just that the wait is annoying?" . Maybe its better to make wait feel shorter.

Potential solutions: Put up mirrors, play music, install a hand sanitizer, install digital signage.

Closing remarks

In conclusion, inversion is a valuable mental model for product managers, enabling them to anticipate challenges, prioritize effectively, and deliver customer-centric products. By embracing the power of inversion, product managers can navigate complexities with clarity and create products that truly make a difference in the market. So, next time you embark on a product management journey, remember to turn the problem around and explore the world from a different perspective.
