The IKEA Effect: Beyond Customer Engagement and Customization
The «IKEA Effect» is a fundamental cognitive bias in Behavioral Design that increases brand loyalty through user-invested effort. However, its success depends on impeccable service design: if friction outweighs gratification, customer stickiness breaks. We analyze how to balance effort and reward to optimize CLV (Customer Lifetime Value) and mitigate operational risks in implementing co-creation strategies.
The “IKEA Effect” gets its name from the furniture giant that emerged in the 1940s in Sweden. This phenomenon describes how people tend to value objects more when they actively participate in their creation or assembly.

In other words, the IKEA effect refers to our tendency to appreciate and want things more when we've put effort into them. By investing time and energy into building something, we develop a sense of ownership and emotional attachment to that object, which increases our perception of its value. This happens even if the end result isn't perfect or if a similar, pre-assembled product would have been cheaper.
This effect is not only applied to furniture. It actually encompasses any situation, both tangible and conceptual, where people invest effort in the configuration or personalization of a product or service within a Loyalty Ecosystem.
For example, when someone meticulously sets up their profile in a new app, they are more likely to feel a connection and use it more frequently, increasing customer stickiness. This “I did it myself” feeling has a special power, and many brands seek to appeal to this phenomenon to build customer loyalty and reduce acquisition costs.
Strategy and Risks: When Effort Creates Friction
The IKEA Effect has significant implications in areas such as User-Centered Design (UCD), marketing, and business management, as it directly influences user perception and experience. However, it's not just about enabling customization, but about making informed and strategic decisions, deeply understanding the business context and needs to avoid premature abandonment.
A great example of a failure in the implementation of this bias is the campaign “Create Your Taste” launched by McDonald's in 2014. Although they sought to involve the customer in the creation process, the campaign faced critical Service Design challenges:
- Complicated interface: The complexity of the process broke the flow of gratification, generating unnecessary cognitive load instead of satisfaction.
- High Costs: The final price exceeded the perceived value of the effort, negatively affecting the brand's perception of affordability.
- Operational complications: Over-personalization increased wait times, degrading key customer retention and satisfaction metrics.
- Disconnect from the value proposition: There was a breakdown in brand consistency, moving away from the promise of speed and simplicity that consumers expected from the chain.
IKEA Effect Application Framework in Gerund
So that the customer's effort translates into business value and advocacy, we evaluate three fundamental pillars:
- Low Friction – High Reward: The effort requested should be accessible, and the emotional reward should be immediate and tangible.
- Alignment: Personalization should reinforce the core brand promise, ensuring the integrity of the positioning.
- Scalability: The co-creation process must be operationally sustainable so as not to cannibalize service efficiency.
Lessons for systemic design
The McDonald's experience leaves us with a clear lesson: the IKEA Effect only works when the creation process is accessible, rewarding, and aligned with the customers' expectations, desires, and limitations. If these elements are not handled properly, the attempt to involve the user can result in frustration and rejection, drastically increasing the churn rate.
