The 8 Wastes of Lean in Healthcare, With Examples

Ask a nurse how much of a shift goes to hunting for supplies, waiting on a callback, or entering the same information twice, and you'll usually hear a sigh before you hear a number. None of that time helps a patient. Most of it is built into how the work is designed.

Lean calls these activities waste. The 8 wastes of Lean in healthcare aren't abstract categories. They show up every day in ways that frustrate patients and the people caring for them, and they're usually more visible from the front line than from the executive suite.

Below, I walk through each of the eight wastes with healthcare examples. Then I get to the harder part: what leaders have to do so people feel able to point the waste out.

The 8 Wastes of Lean in Healthcare

Taiichi Ohno described seven wastes as part of the Toyota Production System. An eighth, the waste of people's unused ideas and skills, was added later. It's hard to say who first proposed it. Norman Bodek has said he did. Either way, most Lean healthcare writing now works from eight.

The point of naming them isn't to sort every activity into a bucket. It's to help people see work that frustrates patients and staff without adding anything a patient would value.

1. Defects

Defects include the error itself, the rework it causes, and the inspection steps added to catch it. In healthcare, some defects harm patients.

• Medication errors, including the wrong dose, the wrong drug, or a missed dose
• Hospital-acquired infections, falls, and pressure injuries
• Lab specimens that are mislabeled or unusable and have to be redrawn
• Coding and billing errors that lead to denied claims

2. Waiting

Waiting is the waste patients notice most, and it costs staff time too.

• Patients in the waiting room, then waiting again in the exam room
• Emergency department patients boarding while they wait for an inpatient bed
• Clinicians waiting on lab results, imaging reads, or a callback
• A discharge order written in the morning for a patient who doesn't leave until late afternoon

3. Transportation

Transportation waste is unnecessary movement of patients, specimens, medications, supplies, or information. Some of it can't be eliminated, but it can be reduced.

• Patients sent between buildings for lab work, imaging, and appointments
• Specimens held and batched before they go to the lab
• Medications handed off more times than necessary on the way from the pharmacy to the patient

4. Overproduction

Overproduction means doing something before it's needed, or more of it than is needed. It's easy to miss in healthcare because it often looks like being thorough.

• Daily labs ordered out of routine rather than clinical need
• Extra tubes of blood drawn "just in case"
• Meal trays delivered to patients who can't eat or have already been discharged
• Reports compiled every week that nobody reads

5. Overprocessing

Overprocessing is work that doesn't add value from the patient's point of view, or work that is more complicated than it needs to be.

• Documenting the same information in several places
• Patients answering the same intake questions for the registrar, the nurse, and the physician
• Approval signatures that get signed without being reviewed
• Forms full of fields nobody uses

6. Inventory

Excess supplies, medications, and equipment cost money to buy, store, and track, and some of it expires before anyone uses it.

• Medications and supplies that expire on the shelf
• Par levels set high because staff don't trust the restocking process
• Personal stashes of supplies tucked into drawers and lockers

Patients waiting in a queue can be thought of as inventory too. A full waiting room usually means flow is broken somewhere else in the system.

7. Motion

Motion is unnecessary movement by staff, as opposed to moving patients or materials.

• Walking to a distant supply room for commonly used items
• Searching for IV pumps, wheelchairs, and other shared equipment
• Unit layouts that don't match how the work flows
• Extra clicks and screens in the electronic health record

8. Unused Human Potential

This is the waste of not using people's ideas, skills, and judgment. I'd argue it's the most expensive one, because it keeps the other seven around.

• Staff ideas that go into a suggestion box and are never heard from again
• People who learn to work around problems instead of reporting them
• Nurses and pharmacists spending time on tasks that don't require their license

Most of this waste isn't caused by people being lazy or careless. It's built into how the work is designed, and the people doing the work usually see it long before it shows up in a report.

What Lean Healthcare Is and Isn't

Lean healthcare is a management system and a way of thinking that helps organizations continuously improve patient safety, quality, access, and staff engagement. Lower cost tends to follow from doing those things well. It isn't the starting point.

The Lean methodology was first developed in manufacturing, but using it in healthcare has never been about treating patients like products. As I describe in Lean Hospitals, it's about designing better systems of care so clinicians and staff can reliably do the right thing for patients without workarounds, heroics, or burnout.

In practice, Lean healthcare means:

• Studying how care is actually delivered, not how the policy manual says it's delivered
• Finding the delays, frustrations, and risks built into processes
• Redesigning systems so quality and safety are built in rather than inspected in later

It also changes who leads improvement. In Healthcare Kaizen, Joe Swartz and I wrote about how the nurses, physicians, pharmacists, schedulers, and support staff who do the work are best positioned to improve it. Leaders still matter a great deal, but their role shifts to creating psychological safety, coaching problem solving, and removing barriers that frontline teams can't fix on their own.

A few principles run underneath all of this. Value is defined from the patient's point of view, not by what's convenient to measure internally. Respect for People means taking concerns and ideas seriously and designing work that makes the job easier rather than harder. And when something goes wrong, the first question isn't "Who made the mistake?" It's "What about the system allowed this to happen, and how do we redesign it?"

Leaders Have to Make It Safe to Point Out Waste

You can teach everyone the eight wastes, but if people are afraid to speak up, improvement boards (and improvement software) stay empty. If mistakes are punished, problems stay hidden. If leaders react badly to bad news, people stop bringing it.

Fear isn't the only thing that keeps people quiet. Ethan Burris, who studies employee voice at the University of Texas, has found that a sense of futility holds people back as often as fear does. If staff have pointed out the same waste for years and nothing changed, they reasonably conclude it isn't worth the effort. Leaders have to show that speaking up leads to action.

The leaders I've seen do this well respond calmly to problems, ask questions before offering fixes, and are open about their own mistakes.

A Management System, Not a Toolbox

Lean healthcare isn't about copying another hospital's tools or huddle boards. It's about building a management system where everyone can identify problems and suggest improvements, leaders coach instead of command, and learning is visible.

Technology, including improvement software for healthcare organizations, can make that system easier to scale and sustain across units and sites. It doesn't replace leadership behaviors. It supports them.

The organizations I've seen make real progress didn't eliminate waste in a single event. They made it normal, every day, for the people closest to patients to see waste, say so, and fix it.
