Quick changeover—a structured methodology for reducing the set-up time for an activity. Set-up is defined as the preparatory task required before an activity can fulfill its intended function. Create a sustainable educational and clinical environment for implementation of the technology. The process should be cost neutral preferable or require only minimal funds from the SODM.
Applying the 5S methodology, it became clear that rather than implementing electrical handpieces technology for all students, the SODM should implement it also for all operatories. The outcomes of the process were intended to eliminate items from the work area in this case the bulky control box on the unit tray, Figure 1 , create a situation in which the student can experience the same setting in the preclinical mannequin area and the main patient clinic, using the electrical handpieces without incurring an unreasonable number of complaints.
It also became evident that the process of connecting and disconnecting the control boxes, which need to be carried and stored during times when students are not in the operatory, should be eliminated. Another challenge was that several student classes had already purchased the systems, and the new setting should also accommodate the existing handpieces.
After several iterations with the suppliers, the following solution was proposed by a new vendor:. The vendor will equip all the operatories in the preclinical and clinical areas with control boxes integrated in the dental unit. This will allow quick connection of the handpieces without the need constantly to connect, disconnect, and store the control box while not in use. The vendor will supply the SODM with adaptors that allow use of handpieces purchased by students from the previous vendor.
The cost for creating the new setting will be incurred by the vendor, therefore being financially neutral for the SODM. A few months after creating the new set-up Figure 2 , the students were surveyed again: the answers denoted a significantly increased level of satisfaction regarding the clinical setting—this was attributed to a significant reduction in set-up time, additional space on the unit tray, need for less storage, and simplified cleaning of the control box.
Answers also showed a statistically significant decrease in the number of students who are unsatisfied with the technical service received and an increase in the number of respondents who did not have the system repaired.
The results show that the intervention that was limited to replacing the control boxes influenced the overall perception of the students regarding the handpieces. The increased number of students who reported that they did not require system repairs can be attributed to the fact that the wear and tear of the new setting is significantly lower because the control box does not have to be repeatedly installed and removed, as needed in the previous clinical setting.
Less service of the control box simplified the process and shortened the turnaround time for technical support and therefore decreased the number of respondents dissatisfied with the service.
This example illustrates how a process that was identified as essential can be improved with lean tools. Using these concepts, a significant impact on the primary customers was achieved, while fulfilling the goals set for the improvement process.
The improvement process was done 4 years ago, and its sustainability is proved and reflected in the on-going student satisfaction with the technology and minimal maintenance requirements. Furthermore, because the process proved to be efficient and successful, other subsequent clinical projects were also addressed using similar tools.

Abstract The evolution of production systems is tightly linked to the story of Toyota Motor Company TMC that has its roots around Keywords: Lean management, Pareto, waste, continuous improvement, healthcare, quality, customer value.
Another valued TMC employee, Taiichi Ohno, who joined the company in , joined the visit and reasoned that the Western production systems had two major flaws 1 : Producing components in large batches resulted in large inventories, and The methods preferred large production over customer preferences Little by little, through much iteration, the Toyota Production System TPS evolved and provided a tool that used innovation and common knowledge, and that functioned well in an environment with different cultural values compared with the Western hemisphere.
The following is a summary of these wasteful activities 16 , 17 : Overproduction—producing something in excess, earlier, or faster than the next process needs it Inventory—the cost of managinga large supply inventory may not be obvious at first glance; beside consumption follow-up and space required to store, there is a need to follow expiration dates and to constantly ensure that the items in the inventory are not technologically obsolete. It was already shown that the overall cost of smaller and more frequent shipments is lower than a large-volume purchase for which a discount was provided Motion—a lot of walking waste can arise from poor design of the working area Transportation—in healthcare this can be evident when moving patients, lab tests, information, etc.
The levels of implementation can be defined at three levels 19 : Micro—operational level outcomes represented by manufacturing-like, managerial and support, and patient-flow cases Meso—strategic level that focuses on financial health of organizations, with potential outcomes being financial, staff morale, and involvement Macro—outcomes of national initiatives such as the National Health Service plan in the UK 20 It was noticed that as implementation of lean principles in healthcare becomes more popular in the USA and Europe, a shift from manufacturing-like to organizational cases is observed in the literature.

Our shipping clerk is very familiar with the way he organized the shelves so he is efficient. When our shipping clerk is absent, we would have a difficult time managing the warehouse and putting away stock. This has allowed great flexibility and efficiency. It reduced pull times tremendously speaking from personal experience. Shoppas Material Handling.
While we still have Kaizen opportunities, our team has made a lot of progress in these areas. These are in the early stages, but something I feel will be beneficial to us once implemented. TLM has improved our customer experience from the time a customer walks in our doors. It's a matter of having better documentation for procedures so they know that they will receive the same experience from us through any of our departments. Most of the time it's tough to get a customer to break away from their facility to visit us but if we are able to have them stop in and see our facility it really increases our chance of solidifying a deal.
We utilize an Andon Board in our shops and parts to track equipment and parts orders. The board used in our shop is literally touched by every person that works in our shops and allows us to identify the status and location of all equipment.
Toyota Forklifts of Atlanta. After our certification we purposed to sustain ASEC activities and make it part of our culture. We then began to implement 5S principles for housekeeping, organization, and sustaining a clean environment.
Once our major 5S efforts were complete, and being sustained, we began developing standardized, repeatable work and processes. Visual Management is meant to show our current condition, identify the outcome and visualize the gap. Our associates develop actions to attack the gap.
