A solar panel manufacturing company is implementing a Lean Six Sigma $($LSS$)$ project to improve

the efficiency of its production line. The company has been facing several issues, including

inconsistent production rates, high defect rates, and excessive downtime. To address these

challenges, the company is focusing on the Improve stage of their LSS project.

Task:

Demonstrate the application of linear regressions in identifying and optimising key process

variables that impact production efficiency.

Develop a flow diagram illustrating the steps taken during the Improve stage, highlighting

where and how linear regression analysis is applied.
