Definition – Lean is a set of operating philosophies and methods that help create a maximum value for patients by reducing waste and waits, The approach was originally derived from the Toyota car company production line system: a continuous process improvement system comprising of structured inventory management, waste reduction and quality improvement techniques,
Lean utilises a continuous learning cycle that is driven by the ‘true’ experts in the processes of health care, being the patients/families, health care providers and support staff, The majority of lean investigations published in the international literature refer to the Toyota management system as applied to health care,
In particular, the Virginia Mason Medical Center’s application of lean ‘became the catalyst for lean health care’ in other health systems, particularly in the United States and the United Kingdom, Other authors refer to Thedacare or simply to a lean management system or lean principles/lean philosophy,
What is the lean method in healthcare?
Applying Lean to healthcare – The concept of Lean management is often misunderstood when it’s applied to healthcare. For example, some see Lean as a euphemism for cutting costs. But that’s far from the truth. Lean in healthcare is about creating value and reducing burdens that patients and staff experience every day.
So rather than focusing on saving money, Lean organizations focus on sustaining high levels of quality, safety, satisfaction and morale. They do this by aligning the entire workforce around a consistent management system and using that system to promote, test and implement process improvements on an ongoing basis.
Although cost savings aren’t the focus of Lean management, they are often an outcome, After all, redesigning tasks and workflows to improve care usually means saving time and other resources. It can have other benefits as well, such as helping workers feel more empowered and engaged and reducing their sources of burnout.
What is lean in process improvement?
What Is Lean Process Improvement? – Lean process improvement helps to eliminate waste from your processes and focuses on the activities which create value for your customers. The approach is based on the idea for continuous improvement and it employs a variety of process improvement tools and techniques to achieve and sustain progress.
What is an example of lean process improvement in healthcare?
Examples of Lean in Healthcare – Lean in healthcare has improved patient satisfaction, increased revenue and decreased overtime work. Likewise, as a result of deploying Lean principles, improvements have been recorded in processing paperwork and scheduling appointments.
Hospitals, clinics and healthcare centres have successfully deployed lean in various areas of their operational processes. One great example of lean in healthcare is the Virginia Mason, By deploying lean tools, the hospital was able to implement a Patient Safety Alert (PSA) initiative. This system was devised for staff to be able to report problems that involve patient safety.
Once reports were made, they were investigated, and necessary solutions implemented. As such, Virginia Mason was able to reduce their liability claims by 74% from 2005 to 2015. More so, nurses in ThedaCare were able to increase their time with patients by 70%.
What are the 5 principles of lean?
Five Key Lean Principles Every Engineer Should Know – The Lean Enterprise Institute (LEI), founded by James P. Womack and Daniel T. Jones in 1997, is considered the go-to resource for lean wisdom, training, and seminars. According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection.
What is Lean and Six Sigma in healthcare?
Both methodologies strive to optimize operations and increase value for patients. However, while Lean focuses on eliminating waste, Six Sigma seeks to reduce variation by decreasing defects to a specific statistical measure.
What is the 5 why process in lean?
Origin of the 5 Whys – The 5 Whys concept was originally developed by Sakichi Toyoda, the founder of Toyota Industries Corporation in the 1930s. But the concept reached a mainstream audience later in the 1950s, when Taiichi Ohno, the architect of the Toyota Production System popularized the 5 Whys concept,
Besides the crucial role he played in Toyota’s manufacturing evolution, Ohno is generally considered one of the early pioneers of Lean thinking. He discussed the 5 Whys of Lean in his book, Toyota Production System: Beyond Large-Scale Production, In it, he introduced the idea as “the basis of Toyota’s scientific approach.” As a company, Toyota based much of its troubleshooting work on a “go and see” philosophy.
In other words, its leadership works to make decisions based on a detailed understanding of what is actually happening on a manufacturing floor instead of relying on what executives of board room members think may be happening. That’s one of the central reasons why the 5 Whys concept requires active input from team members – it does not work as a singular or isolated undertaking.
The 5 Whys concept is based on a simple premise: When a problem occurs, ask the question Why? up to five times, until a viable solution comes into view. The 5 Whys is a problem-solving technique designed to help companies uncover the root cause of a problem. The answer to each additional Why helps teams drill down a bit further, until both the nature of the problem as well as the solution becomes clear.
The 5 Whys can often be helpful in troubleshooting things like product issues, general problem solving, quality control, or process improvement. The process works well for simple to moderate problems, but it is less effective for complex or critical problems.
The simplicity of the 5 Whys makes it ideal for situations that call for a root cause analysis, a systematic process focused on identifying a core problem to be addressed. Clearly identifying the problem to be solved is the first step. If it appears at the outset to be a problem that would benefit from a root cause analysis, applying the 5 Whys technique most likely makes sense.
Conversely, complex situations that require potentially multiple solutions will most likely be served by wider-ranging methods. Let’s say you have Lean teams working to design and produce a new 15-inch laptop. In the design phase, test engineers begin seeing reduced performance in performance tests and benchmarks.
- The behavior is repeatable and consistent: Performance starts strong, but quickly tapers off.
- Using the 5 Whys, it becomes clear that performance degradation occurs due to thermal issues.
- When the processor gets taxed for extended periods, it eventually starts to overheat.
- System engineers can then investigate potential thermal solutions.
They might look at mechanical solutions like decreasing the size of the battery to make room for a larger fan, or maybe even adding a second fan. And what if this issue wasn’t discovered until the laptop was in production and already in the hands of customers? That makes hardware changes much more difficult and costly to implement.
In that situation, engineers may decide to pursue non-hardware alternatives; for example, revisiting fan speeds and timing settings at the BIOS level to keep the processor cooler for longer. Another manufacturing scenario where the 5 Whys might make sense to apply: Imagine you are part of a production team responsible for producing sedans in a specific plant.
The number of cars your team has produced dropped by over 20% compared to previous months. Using the 5 Whys, your team is able to narrow down one part in the production process that continues to slow down the team. Due to part changes, mounting the engine now requires three additional manual steps.
In this case, the team could work with leadership to automate portions of new steps to improve overall production times. Software development is another place where the 5 Whys could prove helpful. You could be a member of a development team responsible for delivering a release candidate to a customer in the next four weeks.
Members of the team voice concern with meeting the delivery deadline. Using the 5 Whys, it’s clear that the development of one key feature is taking longer to complete than anticipated. Hiring more developers is not an option due to budget reasons. After team discussion, the project lead apprises the customer of the situation, proposing a way to deprioritize secondary elements of the core feature functionality.

What is the golden triangle in Lean?
The LEAN controversy: Does it really work? By Adam Prime, President Phase 2 Medical Manufacturing, Inc. Cost has always been an important factor in determining the viability of launching a product into the medical device marketplace. At the center of any OEM/Supplier plan for manufactured goods is the understanding that over time, as volumes increase and a product becomes more mature, the cost needs to come down to remain competitive and increase market adoption.
The challenge in greenlighting a project is that success is predicated on a reduction in manufacturing costs for the product at some projected volume. In order to split the risk and resource allocation fairly, the OEM needs to be focused on accessing the market to achieve those sales volumes and the supplier should be able to demonstrate an improved manufacturing methodology that provides confidence in the ability to get the target costs.
The confidence part of this is based on a supplier being able to demonstrate that improvement methodology is part of its culture. LEAN manufacturing could be a key tenet in the success of a supplier’s relationship with medical device OEMs. However, companies have been burned with LEAN due to poor execution of the principles.
One of the challenges is the overuse of LEAN or other improvement methodologies with no real way to evaluate whether they actually improve processes over time. LEAN takes a lot of work and commitment from the management team. Often the operations professionals that have “mixed reviews” about LEAN have formed those opinions based on a tiptoe LEAN operation– not a fully committed program.
Companies that adopt LEAN need to understand that the work is never really done. In evaluating LEAN among suppliers, assessing supplier’s adherence to the golden triangle can help OEMs determine the level of commitment. The golden triangle consists of standardized work, standardized management, and visual management.
- Of the three, visual management is the key to that ability to analyze improvements.
- One of the simplest visual cues for observation is the use of metrics and visual standards of the operation as a whole.
- If a vendor is not displaying data/dashboards associated with their performance, it means visual management has not been achieved.
Manufacturing partners that are committed to LEAN should be able to show OEMs how they measure it using some of the typical metrics that allow managers and manufacturing employees to know when performance is out of standard. Suppliers should be able to show they focus on adherence to the golden triangle to identify things that are out of standard and have additional tools to identify how to get the process back into standard.
Phase 2 uses tools such as Kanban, kamishiabi, and kaizen events to bring processes back into standard. The culture of LEAN manufacturers should primarily be focused on being on the journey of continuous improvement. There is no “we are LEAN” in the terminology, because, as the definition implies, there is always room for to do better.
