Design Principles

"Optimize service delivery workflows by systematically identifying and eliminating bottlenecks and waste."

Inefficient patient discharge is a critical bottleneck in healthcare systems, leading to extended patient stays and increased operational costs. By applying structured quality improvement frameworks like Lean Six Sigma, design and operations professionals can identify and eliminate waste, thereby enhancing patient flow and overall service efficiency.

06

What This Means for Your Design

Hospitals can make patients leave faster by finding and fixing the slow parts of the leaving process, like a well-oiled machine.

How to use in your project

  • 1.Use the DMAIC framework to structure your design process for improving an existing system or product.
  • 2.Apply simulation tools to test design iterations before committing to physical prototypes.
