Consumers' subjective expectations about how long a product should last significantly influence its actual lifespan, even when these expectations are inaccurate. This user-centred design research insight is drawn from a 2023 study published in Journal of Industrial Ecology. Using Qualitative research (interviews) with 22 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must actively shape consumer perceptions of product lifespan through clear communication, robust design, and by addressing barriers to repair and longevity.

Key Findings

  • 01Consumers generally favor long-lasting products but perceive their value depreciating over time.
  • 02Consumers struggle to accurately estimate expected product lifetimes, and low expectations can lead to shorter actual lifespans.
  • 03Use intensity and user care significantly impact product longevity.
  • 04Consumers often overlook repair as an option due to lack of knowledge, perceived poor value for money, and limited ability.
  • 05Market factors like convenient replacement, new technology, and attractive deals hinder lifetime extension.

Application

Design takeaway

Designers must actively shape consumer perceptions of product lifespan through clear communication, robust design, and by addressing barriers to repair and longevity.

How to apply

When designing new products, consider how to communicate expected lifespan, design for repairability, and potentially integrate extended warranty information into the product offering.

Project actions

  • 01When researching user needs, ask about their expectations for product durability.
  • 02Consider how your design choices might influence user perception of a product's lifespan.
  • 03Investigate how to make products easier to repair or maintain.

Method & Evidence

AimTo understand Dutch consumers' perspectives on product lifetimes, the barriers they face in extending product lifespans, and their reactions to a product lifetime label.
MethodQualitative research (interviews)
ProcedureConducted in-depth interviews with Dutch consumers to explore their views on product longevity, factors affecting it, and their responses to hypothetical product lifetime labels.
Sample22 participants
ContextConsumer electronics and household goods

Variables

IV["Consumer expectations of product lifetime","Perceived value depreciation","Use intensity","Consumer care behavior","Market-related factors (e.g., replacement services, deals)"]
DV["Actual product lifetime","Willingness to repair","Response to product lifetime labels"]
CV["Type of electronic product","Consumer demographics (implicitly, as participants are from the same region)"]
04

Strengths & Limitations

Strengths

  • +Provides in-depth qualitative insights into consumer thinking.
  • +Explores multiple facets of product lifetime considerations, including psychological and market factors.

Limitations

The sample size is small, and the findings are specific to the cultural context of Dutch consumers. The study relies on self-reported data, which can be subject to bias.

Reliability & validity

The qualitative nature of interviews provides rich data but may lack generalizability. Reliability could be improved with a larger, more diverse sample or by triangulating findings with quantitative data.

Think critically

To what extent can designers truly influence consumer expectations about product lifespan, given the pervasive influence of marketing and technological obsolescence?

05

Design Principles

"Product longevity is a co-created outcome influenced by design, user behavior, and market context; designers must address all these facets."

Understanding and influencing consumer expectations around product lifetimes is crucial for designing more durable products and promoting sustainable consumption. Designers can leverage this insight to create products that not only meet but exceed perceived longevity, fostering user satisfaction and reducing waste.

06

What This Means for Your Design

How long people *think* a product will last really affects how long it *actually* lasts. If they expect it to break soon, they might not take as good care of it or might replace it sooner.

How to use in your project

  • 1.Use this research to justify investigating user expectations about product lifespan in your design project.
  • 2.Cite this study when discussing user attitudes towards product durability and repair.

Quick Cite

Paragraph starter

Research indicates that consumer expectations significantly influence actual product lifespans, with low expectations potentially leading to shorter product use (van den Berge et al., 2023). This suggests that design interventions aimed at increasing perceived durability and communicating realistic, longer lifespans could be effective in promoting product longevity and reducing waste.
