Linus’s Law

Image created with Midjourney. Image prompt: Create a 2D minimalistic illustration of a vast, open landscape filled with countless eyeballs of various sizes. In the middle of the landscape, a tiny bug, representing a software bug, is being examined by the nearest eyeballs. The image should convey that with so many observers, the bug is being identified and solved swiftly.

Given enough eyeballs, all bugs are shallow.

Eric S. Raymond

"Given enough eyeballs, all bugs are shallow." This simple yet powerful statement, known as Linus's Law, encapsulates a fundamental principle in software development. The law asserts that the more people who can see a problem, the higher the likelihood that someone will have seen and solved a similar problem before1. Initially coined to describe the value of open-source models, Linus's Law has broad implications for all kinds of software projects and processes. This law was named in honour of Linus Torvalds in Eric S. Raymond's book "The Cathedral and the Bazaar".

Linus's Law in Software Development

Let's delve into three examples illustrating the relevance of Linus's Law in software development:

  1. Code Reviews: Code reviews are a vital part of the software development process, where developers examine each other's code to identify issues and suggest improvements. In line with Linus's Law, more reviewers often mean that bugs and other issues are detected and resolved faster.
  2. Beta Testing: In a large beta-testing phase, a significant number of users test a software product before its final release. This aligns with Linus's Law, as a larger tester base increases the chances of discovering and fixing bugs quickly.
  3. Open Source Projects: Open source projects exemplify Linus's Law. These projects are publicly accessible, allowing anyone to contribute. With countless developers scrutinizing and improving the code, bugs are identified and remedied more efficiently.

Connecting Linus’s Law to Digital Product Creation

In the context of creating digital products, Linus's Law emphasizes the power of collaboration and collective problem-solving. It suggests that a diverse team with varied experiences and perspectives can effectively address problems and improve product quality.

This concept can be extended beyond software bugs to the product development process itself. For instance, when designing a new feature or user interface, getting input from a broad range of stakeholders—developers, designers, product managers, users—can uncover potential issues and help create a more robust and user-friendly product.

In a broader perspective, Linus's Law supports a culture of openness and transparency in software development. Open discussions, shared responsibility, and collective intelligence are not just practices but are core principles that drive the successful development of digital products.

In conclusion, Linus's Law offers a valuable lesson for software development and digital product creation: Collaboration and diverse perspectives are key to identifying and addressing problems effectively. By embracing this principle, we can foster a more inclusive, efficient, and successful software development process.
