The New Rules of Healthcare Platforms (Part 2): Pipe Scale vs. Platform Scale

Platform businesses scale differently than traditional businesses. Platforms scale through network effects. In the previous post, we introduced and described a widely used metaphor: pipes vs. platforms. Traditional businesses are pipes. Their value chains are linear. Value is added at sequential stages before a final product or service is delivered to consumers at the end of the pipeline.
