What are the Key Principles of Six Sigma Lean Design?

Instead of just reducing waste during manufacturing or service delivery, the key principles of lean design is to create products, processes and services that will prevent waste.  There are two categories of lean thinking, these are:

1)     Design process improvement through lean principle applications

2)     Produce products, processes and services that are lean by design

Applying the lean principles to the design processes involves identifying and removing waste from the design process to create a more agile design and reduction of times it take to market.   By mapping out the current design process and meeting the stakeholder’s expectations, this allows room for waste analysis and help with identifications of opportunities. All waste is removed and non-value adding activities are stopped.

Products, processes and services are created lean by design to maximize customer’s value and built with the least amount of waste opportunities. A good understanding of the stakeholder’s value lever and what processes deplete the value of stakeholders are important.

Here are a few examples of non-value adding processes and activities for stakeholders to avoid or reduced where possible:
  • Difficulties with storage and operation
  • High costs of service delivery
  • High skill needed to use
  • Material s with high cost and low availability
  • Multiple tests and inspections
  • Not environmentally friendly
  • Sensitivity to noise and variations
