LEAN project has helped the company create an SOP for the customer service workers and the cashiers to reduce the finding time and make the inventory management easy and manageable. The team members also mutually agreed on creating a standard manual of 5S practice to guide the business operation at PTAF. It will then be used at three central locations- small equipment store, payment counter and electrical store. The 5S practice has improved the in-store environment and storage system, reducing the lead time in the selling process and inventory management. PTAF has made significant progress in its operations after the implementation of the LEAN program. Through Project 1, the company made tremendous progress in lead time where prior to LEAN implementation, it needed approximately 34 minutes to complete a whole selling task. After implementing LEAN, it only needs 27 minutes which brings the total reduction to 21 percent. The Process Efficiency and First Time Quality rate also increase from 60 percent and 0.95 to 63 percent and 0.98, respectively.
