Short answer

Designers should consider how platform mechanics, cost structures, and reward systems can be subtly adjusted to attract and retain higher-quality complementors, even if it means a larger influx of lower-quality participants initially.

Key Findings

  • 01Small, incremental changes in platform design related to minimum development costs and non-pecuniary payoffs can cause the market to 'bottom out' for amateurs.
  • 02A 'bottomed-out' market attracts a large number of low-quality developers who remain active on the platform.
  • 03Amateur developers do not appear to crowd out the development activity of top-tier developers.
  • 04The 'bottoming-out' phenomenon is associated with a significant increase in the generation of high-quality products.

Application

Design takeaway

Designers should consider how platform mechanics, cost structures, and reward systems can be subtly adjusted to attract and retain higher-quality complementors, even if it means a larger influx of lower-quality participants initially.

How to apply

When designing or iterating on a platform, analyze the current complementor mix and identify key design levers (e.g., onboarding friction, fee structures, recognition systems) that could be adjusted to favor more professional or higher-quality contributions.

Project actions

  • 01Consider how your design choices might attract different types of users or contributors.
  • 02Think about the economic and psychological factors that influence user engagement and contribution quality.

Method & Evidence

AimHow can platform owners strategically influence the composition of their complementor base (amateurs vs. professionals) through platform design to enhance product quality?
MethodEmpirical analysis of platform data
ProcedureThe study analyzed data from mobile app developers to observe the impact of platform design changes on the behavior and quality of amateur and professional complementors.
ContextDigital platforms, specifically mobile app development ecosystems.

Strengths & Limitations

Strengths

  • +Provides empirical evidence from a real-world platform ecosystem.
  • +Highlights the nuanced relationship between design, user behavior, and market outcomes.

Limitations

The complexity of real-world platforms makes it difficult to isolate the exact impact of specific design changes. Measuring 'quality' can be subjective.

Reliability & validity

The study's reliance on observational data from a specific market may limit generalizability. The definition and measurement of 'quality' are critical for validity. Replication across different platform types would enhance reliability.

Think critically

To what extent can platform owners truly 'control' the quality of complementor contributions through design, or are external market forces more dominant?

05

Design Principles

"Platform design should strategically manage the cost and reward landscape to attract and cultivate high-value complementors, thereby enhancing overall product quality and market innovation."

Understanding how platform design influences the type of complementors attracted is crucial for fostering innovation and market growth. Designers and product managers can leverage these insights to cultivate environments that attract and retain high-quality contributors, thereby enhancing the overall value and success of their platforms.

06

What This Means for Your Design

Making small changes to how easy or rewarding it is to build things on a platform can change who builds them, and sometimes this leads to better quality stuff overall, even if lots of people are still trying.

Quick Cite

Paragraph starter

The research by Boudreau (2018) suggests that subtle platform design modifications, particularly those affecting the cost of participation and non-monetary incentives, can strategically shift the complementor base from amateurs to professionals. This shift, while potentially attracting a large volume of lower-quality contributors, has been shown to correlate with a significant increase in the generation of highest-quality products, indicating that platform owners can actively curate their ecosystem for improved output quality through thoughtful design.
