7 Wastes of Lean


Sharpen your competitive edge by eliminating the 7 wastes of lean in your organization.

Recession or boom, companies need to sharpen their competitive edge by applying Lean Management principles to cost reduction by eliminating the non-value-added activities or waste from the value stream processes.

Be Lean

In the Lean Management philosophy, we group all activities in the organization into two categories: 

  • value-added (VA) activities
  • non-value-added (NVA) activities.

In the context of Lean Management, we view VA and NVA activities from the customer perspective. 

VA activities bring higher value to products and services. Examples include

  • answering customer queries
  • entering orders
  • ordering materials
  • laying foundation
  • creating codes
  • assembling parts
  • shipping of goods to customers.

Customers are willing to pay for these improvements which can change the form, fit or function of a product or service.

On the other hand, NVA tasks do not increase market form or function.

Examples of Non Value Added activities include

  • filing
  • copying
  • recording
  • waiting
  • counting
  • checking
  • inspecting
  • testing
  • reviewing
  • obtaining approvals

You need to eliminate, simplify or reducing the 7 wastes of lean as much as possible. By tackling waste from an end-to-end business process you

  • improve the value of your products and services
  • achieve significant cost reduction
  • strengthen cash flow
  • emerge from a downturn with a stronger and more competitive profile.

7 Wastes of Lean

There are seven waste types in a manufacturing environment.

Studies have shown that in a typical organization, some 90% or more of all activities fall into the NVA bucket.

Although the explanations and examples provided below may be more relevant for manufacturing industries, the concepts can be universally applied to service industries as well.

The 7 manufacturing wastes are:

1) Waiting.

  • idle time resulting from waiting for materials and information
  • email queues from customers
  • delayed shipments
  • lot processing delays
  • capacity bottlenecks
  • unbalanced workload
  • long setup times equipment
  • system downtime

Eliminate the Waste

The ability to find waste in your organization is the first step towards their elimination.

For the next step set up a problem solving teams and enable them to reduce or eliminate the waste. Use the common problem solving technique of PDCA (Plan-Do-Check-Act).

Involve your employees in problem solving or process improvement. They can identify sources of waste or savings that you might not be aware of.

Do note that not all waste equate the same. You need to identify the “right waste”– those that have the greatest impact on the business case or bottom line.

For waste elimination to be successful and sustainable, an organization’s senior executives need to adopt a mindset that cutting waste to cut costs creates an on-going journey of continuous improvement.

Senior executives need to avoid treating waste elimination as another one-off “tool” or quick fix.
