Total: All Encompassing or Involving Everybody?
“Total” is used in the names of improvement programs like Total Quality Control (TQC), Total Productive Maintenance (TPM), Total Quality Management (TQM), or Total Flow Management (TFM), but the meaning is different on both sides of the Pacific. In the US, a Total program addresses all the issues related to its object; in Japan, it involves everybody.
When Armand V. Feigenbaum coined the term Total Quality Control in 1951, he meant that Quality Control should start with product development and end with customer support. When Kaoru Ishikawa took the concept to Japan, the acronym TQC was retained, but “Total” translated as “Zensha teki” (全社的), meaning “Company-Wide,” implying the involvement of every department in the organization. A more precise translation “Zenyin sanka” (全員参加) was later introduced, which means “with participation by every employee” and shifts the emphasis even further. Back in the US, the notion of involving everybody arrived in the 1980s when TQC morphed into TQM, but elsewhere, as in Euclides Coimbra’s TFM, it means encompassing an entire supply chain.
Programs that “involve everybody” are programs that every employee is the company must participate in. They are not volunteers but draftees. Understandably, such programs are difficult to implement, and often result in individuals just going through motions to humor their bosses and wait out the program. When joining a company, employees accept rules pertaining to working hours, compensation, expense reports, and interpersonal relations, but these general rules at the corporate level do not specify, for example, which tools are to be used in each job. Individuals don’t necessarily get to choose, particularly in production, but the standards they follow are set at a lower level than top management.
Starting a program that is “Total” in the Japanese sense means extending the reach of corporate mandates. It is easier to do in organizations to which employees have a career commitment than where employees are recruited for specific skills that they have acquired and can re-market elsewhere. Be it easy or hard, you have to consider whether it is wise. A company-wide program is a centralization effort and reduces the autonomy of lower-level business units. As most companies are trying to go in the opposite direction, you really don’t want to start such a program unless (1) its benefits are obvious, and (2) there is no other way.
A TQM program may mandate that the Plan-Do-Check-Adjust (PDCA) process be used when implementing any change throughout the company. Since everybody must participate, the PhD-level scientists at R&D will be required to undergo PDCA training and to formally use it to organize all their activities. As a group, they will be offended and some may quit. Elsewhere in the company, project leaders will dutifully reports their action items as being in a state of P, D, C or A. The organization can claim to be on board with the program but truly is not.
5S, on the other hand, is a program that can only be successful if everybody participates. The benefits of 5S are not easy to quantify, but everybody likes the outcome: given the choice of working on a shop floor with or without 5S in place, few would choose without. The problem is that even fewer show any enthusiasm for doing the work necessary to achieve and sustain this outcome, and this resistance can only be overcome if everybody from top management on down gets physically involved. When touring Japanese plants, you so often see the plant manager pick up a stray scrap of paper off the floor and put it in a dustbin that you feel the incident has been staged, but the message is clear: everyone should behave as if the tidiness of the whole plant depends on the individual behavior of each.
A more modern and successful program involving all employees is Hoshin Planning, a strategy deployment approach that is well described in Pascal Dennis’s Getting the Right Things Done. It results in employees having small, actionable sets of strategic directions, determined with their input and consistent across levels. It is much more sophisticated than the target numbers game that management-by-objectives has degenerated into in many companies, and the vertical and horizontal interactivity of the process makes it impossible for any segment of the organization to opt-out.
A company-wide program is implemented top-down, starting with top management and cascading to the shop floor, with appropriate training at each level. It is different from Robert Schaffer’s Breakthrough Strategy, which starts with a pilot projects effecting a deep transformation of a small segment of the organization, whose success makes it go viral. By providing rapid improvements and building the skills base, the breakthrough strategy bootstraps the Lean transformation of a plant but can take it only so far. Once the leaders of local projects start wondering what their successes add up to and where they are leading, they are ready to pull together and take on the challenge of involving all employees in the parts of Lean for which it is necessary. It is top management’s role to sense when an organization is ready for this transition.

Did Citroen Use Too Many Phone Calls and Emails in Developing the C5?
Wiegand’s Watch is a monthly letter from Dr. Bodo Wiegand, who runs the Lean Management Institut, the German affiliate of the Lean Enterprise Institute. This month, he focuses on what he perceives to be a wasted use of email and cell phones in the development of the Citroen C5 car. Following is a translation of his letter, followed by my comments:
My first reaction is to wonder what is wrong with >1,000 people involved in a multi-year project like the development of a new car communicating extensively? It brings to mind Frederick Brooks’s famous audit of the Tower of Babel project in The Mythical Man-Month. The goal was clear and its lack of feasibility played no part in the failure. Human and material resources were plentiful in Mesopotamia, and were not a problem either. What caused the project to fail was that team members could not communicate.
Product development generates many documents that need to be reviewed, discussed, annotated, updated, revised, and organized. These documents must also be available easily to all those with a need to know, and kept secret from all others. I don’t know on what basis Dr. Wiegand concludes that a large part of Citroen’s communications by phone and email were waste. For all I know, they may have been meaty technical exchanges that improved the design of the C5…
Of course, you don’t need electronic means of communication if everybody is in one big room, but that only works for teams that are small enough. You would need a convention hall for a team in the latter stages of car development, and some activities, like testing in a hot desert or snow, or ramping up production, take place at multiple locations. While always desirable, face-to-face communication is not feasible for everything at all times.
Just based on the statements from Citroen, if I would fault them for anything, it would be for relying on nothing more sophisticated than phones and emails, which is so 20th century. There are now collaboration and on-line meeting tools that combine much richer exchanges with better data security and revision control. For example, engineers at different locations can view the same drawing on their screens, annotate it while discussing through an audio conference, and read each other’s body language through webcams.
Instead of having multiple copies of documents floating around in individual mailboxes, you can keep them in a library on a server to ensure that all participants in a discussion are looking at the same version, and to prevent these documents from leaking out.
You can also fault emails for lacking the kind of structure you find in A3 reports, which discipline authors in providing particular data items while helping readers find them. But again, more advanced communication tools can provide that structure through on-line forms .
For voice communication, there are also alternatives to cell phones. For people whose work causes them to move around within the range of WIFI network, for example, there are wearable devices that allow them to call each other by name and communicate by voice instantly, as if they were side by side.
So maybe the issue is not that Citroen C5 development used to many engineer-years communicating, but that, next time, they should use the state of the art to do it.
