Canada, a Model for Australia’s Automotive industry? | Business Spectator
See on Scoop.it – lean manufacturing
“Ford Australia’s move to close its two Australian plants from 2016 and transition to import-only brands only reinforces the sense of a looming death knell. But that isn’t the case with every developed-world auto sector struggling to compete with high domestic production costs and cheaper, mostly-Asian-built imports. Canada’s auto sector has also struggled with factors that would sound familiar to an Australian onlooker, such as its own high dollar, volatile domestic demand, offshore competition and wavering government subsidies.
But as much as those conditions in Canada instigated uncertainty, cuts and job losses, that struggle, which gained pace as the global financial crisis took hold, has also produced a level of productivity-focused innovation worth noting for any manufacturer or policymaker wondering if Australia’s auto sector has crossed its rubicon.”
Ford is closing its plants in Australia, which threatens the entire local automotive industry. The author looks to Canada for a model Australia could follow for this industry to survive and thrive. The article is mostly about Canada, and specificially about the Magna Dortec door latch plant Northeast of Toronto.

Using videos to improve operations | Part 1 – Overview and Motivation
This is the first in a series of posts about the use of video technology to improve operations. This technology is now so pervasive that it is nearly impossible to buy a phone that does not include a camera capable or recording footage that is good enough for broadcast news. Journalists use amateur videos to show storm damage or expose human brutality. We use it to identify improvement opportunities in operations.
For long-time followers of this blog, this is closely based on comments I posted 18 months ago about a news article on the application of a sports video analysis package to manufacturing. The forthcoming installments, on the other hand, are completely new.

Frank and Lillian Gilbreth did it 100 years ago
Motion pictures have a long history in manufacturing. In 1895, the first film ever publicly projected onto a screen showed women leaving the Lumière Brothers factory in Lyon. In 1904, the American Mutoscope and Biograph Company shot several scenes in Westinghouse factories. In 1913, Frank and Lillian Gilbreth were probably the first to use this new technology to analyze operations, and a compilation of their films is available on line, which shows that, from the very beginning, the camera was much more than a substitute for the stopwatches used by Taylor. As is obvious from watching the Gilbreth films, where Taylor measured in order to control, the Gilbreths observed in order to improve. Taylor’s greater fame or notoriety, however, obscured this fundamental difference in the public mind, and made workers as wary of cameras as of stopwatches.
According to psychologist Arlie Belliveau:
In other words, these pioneers already understood that, unlike the stopwatch, this technology enabled the operators to participate in the analysis and improvement of their own operations.
Until recently, however, the process of recording motion was too cumbersome and expensive, and required too much skill, to be massively practiced either in manufacturing or in other types of business operations. In addition, most managements failed to use it in as enlightened a way as the Gilbreths, and manufacturing workers had a frequently well-founded fear that recordings would be used against them. As a consequence, they were less than enthusiastic in their support of such efforts.
Use in Setup Time Reduction
Setup time reduction is probably the first type of project in which it was systematically used, first because the high stakes justified the cost, even in the 1950s and second because its objective was clearly to make drastic changes in activities that were not production and not to nibble a few seconds out of a repetitive task by pressuring a worker to move faster.
The Vanishing Cost of Shooting Videos
Technically, the cost of shooting videos has not been an issue since the advent of the VCR in the 1980s. Analyzing a video by moving forward and backwards on a cassette tape, while it appears cumbersome today, was far easier than dealing with film. The collection of data on electronic spreadsheets also eliminated the need to use counterintuitive time units like “decimal minutes.” Adding columns of times in hours, minutes and seconds was impractical manually but not a problem for the electronic spreadsheet.
With videos now recorded on and played back from flash memory, and free media-players as software, not only is moving back and forth in a video recording is easier, but the software maps video frames to the time elapsed since the beginning. We could manually transfer timestamps read from the bottom of the video player software window into electronic spreadsheets and have the spreadsheet software automatically calculate task times as the differences between consecutive timestamps.
Analyzing Data in Video Form
While this approach has been a common practice for the past 15 years, video annotation software is available today, which helps break down the video into segments for steps, label them, categorize them, and analyze them.
You can also use it to structure the data and generate a variety of analytics to drive improvements or document the improved process through, for example, work instructions. Over the previous approach, video annotation has the following advantages:It automates the collection of timestamps. Reading times on the video screen and typing hem into an Excel spreadsheet is tedious and error-prone. Plowing through the details of a 30-minute is tedious enough already.
“Video time studies” is too restrictive a name for what we do with videos. It implies that they are just a replacement for a stopwatch in setting time standards. But what we really do with videos is analyze processes for the purpose of improving them, and this involves more than just capturing times. The primary pupose of the measurements is to quantify the improvement potential to justify changes, and to validate that they have actually occurred.
Remaining Challenges
Putting this technology to use is not without challenges. Video files are larger than just about any other type we may use, be they rich text, databases, or photographs. And they come in a variety of formats and compression methods that make the old VHS versus Betamax dilemma of the VCR age look simple. More standardization would help, and will eventually come but, in the meantime, we have to learn more than we want to know about these issues. Functionally, the next technical challenge is the organization of libraries or databases for storage and retrieval of data captured in the form of videos. The human issues of video recording and analysis of business operations, on the other hand, remain as thorny as ever.
