Companies should know about the use of lean manufacturing principles to help businesses clean up efficiencies, work smarter, and remain competitive in any manufacturing operation.
FREMONT, CA: The principles of lean manufacturing are foundational and help manufacturers and various industries create production processes that eliminate inefficiencies and build better-quality products that align with consumer demand. These principles include five major aspects, such as identifying value, mapping the value stream, creating flow, establishing pull, and seeking perfection.

Identify Value
The primary principle of lean manufacturing is to identify what customers value and how products meet those values. The idea behind this principle is that manufacturers should not waste time, money, and labour on products that are unnecessary for customers. Manufacturers choose a product and process, incorporating only what is necessary to please the customer and eliminating these wasteful steps.
Map the Value Stream
Businesses should identify the value of a product throughout its entire lifecycle. This includes mapping a product’s value from design to customer use to disposal. This helps them better understand those values and reduces production steps that do not contribute to value.
Create Flow
This procedure deals with optimising operations on the production floor to create a process without holdups. A product should flow from production to shipping without interruption. This can be achieved by analysing how people, equipment, and materials are used to recognise ways the shop floor can be optimised. An enhanced flow results in reduced production time, inventory size, and material handling.
Establish Pull
This principle is pivotal to using a pull-based production system rather than one that is push-based. Push-based systems involve buying supplies and moving through production even when there is no order. This results in large inventories and a lot of work in progress. On the other hand, pull systems begin with a product order. Materials are purchased and work is performed according to orders to minimise inventory, increase output, and eliminate overproduction and errors. Moreover, a pull method prevents inventory from expiring.
Seek Perfection
Although seeking perfection seems straightforward, it is the hardest principle to embrace and maintain. Seeking perfection requires constant improvement and a culture shift throughout the entire operation. This helps companies create a culture in which workers seek perfection, focusing on small, valuable changes rather than accepting the status quo. Eventually, having the priority of perfection in all areas increases efficiency, productivity, and quality.
There are various approaches and tools used in manufacturing to help with the adoption and integration of lean manufacturing principles. Using the 5S methodology, executing a quality management system (QMS), and using an enterprise resource planning (ERP) system promotes efficiency and further streamlines manufacturing processes.
