Sewn Products Case Study
Sewn products manufacturers often rely heavily on manual labor. While some degree of automation is typically involved—usually early in the value stream such as spreading material and cutting markers—this approach often results in large work-in-progress (WIP) batches, high inventories and long lead times as bundles of materials sit idle.
One of Stream's clients is a manufacturer of specialty apparel and personal protective equipment for emergency responders and military personnel around the world. The client was facing several critical business issues when Stream first started working with them.
Stream worked with this client to dramatically transform their main production facility. Stream used a three-step approach to document the current state and implement innovative improvements across four major value streams producing firefighter protective gear.
PROBLEM
SLOW FLOW OR SLEEPING INVENTORY
Bundles of mixed products were piled on carts and pushed from process to process. Bundles had to be opened, sorted and re-bundled at each process.
THE RESULTS
The improvements started yielding results immediately in various parts of the plant, and in the end, the results totaled:
Before | After | % Change | |
WIP (units) | 3,012 | 162 | 94.6% |
Lead Time | 15.1 Days | 6.5 Hours | 94.6 % |
Travel Distance | 1,347 ft. | 402 ft. | 70.2 % |
Customer Complaints | 348 units/mo | 35 units/mo | 89.9 % |
