Long lead times, missed delivery times, demanding or nonpaying customers, too many unsuccessful quotes, too much shop overtime—life isn’t always smooth for job shops.
The term "job shop" refers to custom manufacturing and make-to-order businesses. These firms share some common characteristics that differ from repetitive manufacturing settings, for example using a quoting process to secure work, and producing work on an order-to-order basis to meet customer specifications. While some job shops do purely custom work, many manufacturing firms have a mix of custom and repeat orders.
Value Stream Mapping
One of the most valuable improvement tools for job shops is also a simple one - Value Stream Mapping - this technique involves drawing a visual representation – a map– of every step in the product’s path, or "value stream," from "quote to cash"– from quote/bid, through engineering, to the shop floor and out the door. Given the significance of front-end processes in securing orders, it is particularly critical for job shops to include them in their value stream map. The resulting map helps companies scrutinize each aspect of their operation and identify areas for improvement.
