Sakichi Toyoda was the inventor of automatic looms who founded the Toyota Group. He invented a loom in that would stop automatically if any of the threads snapped. His invention opened the way for automated loomworks where a single operator could handle dozens of looms.
They use a series of worksheets to simplify the creation of these standards.
The first one is a production capacity sheet to define what capacity you have available. The second one is a standard work combination table to define when the operator is doing what.
The third one is a standard work layout sheet to help with the layout and arrangement of the machines. While there are many different ways of doing this, I like the Toyota approach. Lets start with the Production Capacity sheet.
If there are different ways that things can be done, then some of these must be better than others. The idea of standard work helps employees perform consistently. Please note that any good work standard — or even any good working procedure — needs a lot of input from the people who actually do the work!
The naming of this method and the three sheets that I will show you in this and the next two posts is by no means used consistently across the lean community, and there are many different similar names. However, this may lead to confusion with the more general standardized work or work standards meaning there is a standard of some kind, but not necessarily this method.
Definitely many thanks to Michel Baudin for letting me know all those many names and their origins. Where to Use It The production capacity sheet helps with the calculations of the line capacity, and the standard work layout helps with the line layout.
The standardized work combination table defines the working standard of the operator. Each of these address a specific issue in planning and standardization. Preparations Before we can start, we need a few pieces of information.
We need to know what the line has to do. The different process steps need to be defined or known. Ideally, we already have a line, but it would also work for a yet-to-be-built line as long as we know the process steps.
We need to know the target speed of the line. How fast should the goods be produced? The resulting metric here is the target cycle time. How fast should each machine be without breakdowns, delays, and other losses measured in seconds or minutes, hours, etc. We need to know the speed of each machine, including the time needed for the operator and the time needed at which a machine can work without the operator as well as.
At Toyota, this is usually measured using stopwatches if the line already exists. Other countries where the unions disagree with stopwatches need to use different methods, usually a system of predetermined motions e.
The key metrics here are the manual work time and the additional machine work time. Production Capacity Sheet The production capacity sheet is an overview with the basic data and some simple calculations regarding the machines in the line.Toyota 4Runner Forums for all 4runner models ranging from 1st gen to Lots of build threads, pictures, discussions and advice.
The Toyota Way is a set of principles and behaviors that underlie the Toyota Motor Corporation's managerial approach and production system. Toyota first summed up its philosophy, values and manufacturing ideals in , calling it "The Toyota Way ".
It consists of principles in two key areas: continuous improvement, and respect for people. A Study of the Toyota Production System: From an Industrial Engineering Viewpoint (Produce What Is Needed, When It's Needed) [Shigeo Shingo, Andrew P.
Dillon] on tranceformingnlp.com *FREE* shipping on qualifying offers. This is the green book that started it all -- the first book in English on JIT, written from the engineer's viewpoint.
When Omark Industries bought copies and studied it companywide. Many manufacturers imitate the Toyota Production System or its variant, Lean Manufacturing.
The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and tranceformingnlp.com TPS organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers. The system is a major precursor of the more generic "lean manufacturing". -Quality must be built in during the manufacturing process!-If equipment malfunction or a defective part is discovered, the affected machine automatically stops, and operators cease production and correct the problem. Toyota’s renowned production system (TPS) has long demonstrated the competitive advantage of continuous process improvement. And companies in a wide range of industries—aerospace, metals.
Most improve their operations but few approach the efficiency and quality achieved at Toyota. The usual list of elements and techniques such as kanban, workcells and SPC do not capture the essence. Many manufacturers imitate the Toyota Production System or its variant, Lean Manufacturing.
