On-Time Invoicing: Vendor Management 


Ingram Lightning Source Inc.: Lean Process Improvement Engineer


S: Vendors complained of not receiving timely payments from the company for major materials needed for plant operation. Negotiations were impacted and vendors wanted to discontinue us as a customer.  

T: The problem identified were that roles and responsibilities were not clarified in who performed what work during the process. Department visibility of document and invoice handling needs were non-existent without manually having to look for it.  

A: I created a Value Stream Map and applied a Lean Six Sigma approach to identify priority areas to guide the team to implement opportunities on.   

R: First Pass Yield went from 19% to 93% in the first implementation. Vendor relationships improved. Contract negotiations brought the company material savings with improved invoicing structures.
