In the world of lean manufacturing and process optimization, the concept of “muda” refers to the Japanese term for waste. It is an essential principle in Lean thinking, aimed at identifying and eliminating any non-value-adding activities or processes in a business operation. Traditionally, there are seven recognized forms of waste in Lean thinking, including overproduction, inventory, motion, waiting, over-processing, defects, and transportation. However, as businesses evolve and become more complex, a new muda has emerged: communication. In this article, we will explore why communication is now considered the eighth muda and why it’s crucial to eliminate communication waste in the workplace.

Understanding the Traditional Seven Wastes

Before delving into the eighth muda, it’s essential to have a basic understanding of the traditional seven wastes:

Overproduction: Producing more goods or services than what is needed, leading to excess inventory and storage costs.

Inventory: The cost associated with maintaining excessive stock or work-in-progress, which ties up resources and can lead to obsolescence.

Motion: Unnecessary physical movements by employees to complete their tasks, leading to inefficiencies and potential injuries.

Waiting: Time spent idle due to inefficient processes or delays, leading to lost productivity.

Over-Processing: Adding more value to a product or service than what is required by the customer, which wastes time and resources.

Defects: Errors in the production process that require rework, leading to increased costs and customer dissatisfaction.

Transportation: Unnecessary movement of goods or information, which can lead to delays and increased costs.


The Emergence of the Eighth Muda – Communication

Communication is an intrinsic part of any organization, and it’s crucial for success. However, when not managed effectively, it can become a significant source of waste. Here are several reasons why communication is now recognized as the eighth muda:

Information Overload: In today’s digital age, we are bombarded with vast amounts of information daily. Mismanaged communication channels and excessive emails, meetings, and messages can overwhelm employees, leading to wasted time and reduced productivity.

Lack of Clarity: Poorly conveyed information or unclear messaging can lead to misunderstandings, mistakes, and rework, all of which contribute to waste in the workplace.

Inefficient Meetings: Unproductive meetings are a notorious source of wasted time and resources. Meetings without clear objectives, participants, or outcomes often lead to unnecessary discussions and a lack of action.

Overcommunication: When too many people are involved in decision-making or approvals, it can slow down processes and hinder progress. This is particularly true in hierarchical organizations where layers of approval are required.

Siloed Information: When critical information is hoarded within departments or teams and not shared across the organization, it can result in duplicated efforts and missed opportunities for synergy.
