Lean in the operating room

Via Scoop.it – lean manufacturing
This article points out that Lean in health care shouldn’t be just about administration and patient handling but should reach into the medical and surgical acts, and presents the case of a Danish hospital doing just that.   After all, the current operating room procedures are based on the work of industrial engineer Frank Gilbreth in the 1910s. Maybe it is time to revisit them…

I'm six sigma - I'm Lean

Dec 9 2011

Six Sigma R.I.P.

If you google Six Sigma, you get the impression that it is a going concern, with all sorts of organizations offering training and consulting on how to implement it. If you dig just a bit deeper, you run into a Business Week article from June 11, 2007 entitled Six Sigma: So Yesterday? It explained how the best known Six Sigma icons, like GE, 3M, Home Depot, or Motorola were “dialing it back.” Whatever this may mean, it is difficult to imagine ambitious employees in a company showing enthusiasm for a program that is being “dialed back.”

The same article attributes the following statement to GE’s former CEO Jack Welch about Six Sigma: “Even if the concept is applied in areas where perhaps it shouldn’t be, it’ll be worth it in the long run.” It makes you wonder how he would have liked to work in such an area, with management knowingly pressuring him to implement an irrelevant method.

Now that the Six Sigma craze is over, there is no much merit in criticizing it. Ever since I was first exposed to it in the 1990s, I have perceived it as a welcome update of the now 90-year-old tools of Statistical Process Control (SPC), useful in industries where, if your process is mature, your product is obsolete. This applies in semiconductors and other high-technology manufacturing sectors, but not in mature sectors like automotive.

It never struck me as having the potential to be a revolution in business or comparable in scope and impact to Lean. Saying so 10 years ago made many people angry but I did worse: I put in writing, in an article entitled Six Sigma and Lean Manufacturing that was published by the SME in a Six Sigma newsletter in July, 2002.

If you google Motorola +Six-Sigma, you learn that Motorola no longer teaches Six Sigma business improvement. Given that Motorola is where Six Sigma was invented, the equivalent would be for Toyota to dump Lean. Maybe it is time to dial down the Six Sigma training programs.

Citroen C5

Dec 7 2011

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:

€ 16 million wasted in the development of the C5 car
Today I was at the airport and saw a billboard.
The development of the C5 at Citroen used 1,410,475 cell phone calls and 3,155,546 e-mails. This is madness. If  a phone conversation lasts an average of 2.5 minutes, it works out to 14 670 man-days or 73 man-years.
Assuming  writing a  technical e-mail on average takes four minutes and that it is read six-times, then these emails took up  65,741 man-days or 321 man-years. Assuming that 50% of these cell phone calls and 50% of e-mails were necessary but non value-added, this adds up to 40,000 man-days or 200 man-years, or € 16 million were needed to do the following:

  • Fix processes that are out of control.
  • Define nterfaces that were not specified.
  • Rethink procedures with qualitative gaps.
  • To answer questions.
  • To solve problems.

What a huge waste!
What a potential for improvement!
And Citroen boasts about it.

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.

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.

Another take on the issues raised in Waiting for each other. Bringing waiting taxis to waiting customers in batches seems like another bad idea.

Tower of Babel

Dec 1 2011

The Project Game

The developments of the Airbus A380 and the Boeing 787 were both more than two years late. You might think that these two master aircraft builders would know better. Such performance, however, is not the exception. Generally, from kitchen remodeling to the development of a product or a production line, projects tend to be behind schedule, over budget, or both.

That it is technically possible to do better even with a large-scale project involving new technology is illustrated by the Apollo program: it reached the goal set by JFK 5 months ahead of the deadline at a cost of $24B, accurately estimated in 1961. Even NASA, however,  did not repeat its Apollo performance with the Space Shuttle. 100 years before, another major project, the transcontinental railroad, was also completed in record time at a cost that was consistent with original estimates.

It is therefore legitimate to ask why we are not able to do better, given the tools we now have. The key is that project and program management are treated like technical fields when they should be viewed as games, meaning that outcomes are the consequences of decisions made by several independent agents. In project management as described in the PMBOK, you break a project down into smaller tasks, to which you assign durations, resources and constraints of timing or precedence. Then you run calculations that produce Gantt charts, load profiles for resources, the critical path, etc. The most commonly used tool is the Critical Path Method (CPM), as implemented in packages like Microsoft Project. Then there is Eli Goldratt’s Critical Chain Project Management, focused on resources, and the Design Structure Matrix (DSM) to manage task iterations.

These are logically consistent models, and good fodder for presentations, but cast aside in daily project management in favor of the primitive action-item lists. The most obvious problem with the use of the tools is that durations for elementary tasks are not known, and that I have never seen an organization make a serious effort at collecting this data. A project task is not like an assembly operation that you can time with a stopwatch or record on video. And project work is never completely repetitive: if you keep repeating the same action, it may be called production or transaction processing, but not project work. Since you have never done this project task before, you cannot tell exactly how long it will take, but you can get lower bounds based on its content — for example if it involves driving 60 miles or waiting for paint to dry — and you could estimate it based on similarities and differences with tasks you have done before, if you had kept track of them. Engineering work is organized by project, and the time of engineers is tracked through time sheets, but these sheets are filled out after the fact by the engineers themselves for accounting, and are not accurate.

There are ways to estimate task times better, but that is not the main concern of project managers. Instead, their thinking is centered on sentences that begin with “Nothing else matters if…” Initially, a manager commissioned to lead a project has to come up with a plan that needs to be approved and nothing else matters. The purpose of the plan is therefore not estimation but persuasion. How this is to be accomplished cannot be stated in a generic way, because it obviously depends on who is to persuaded. What is a constant is that the project manager is selling, and will do whatever it takes to close the deal.

Imagine a king who is single and wants an heir. He solicits three members of his council to manage the project and gets the following responses:

  1. The first adviser claims that he can organize to produce an heir in four months.
  2. The second adviser quotes three to five years, taking into consideration the need to find an appropriate consort, follow the complex protocols of royal engagements and weddings, and let nature take its course.
  3. The third adviser quotes nine months.

Assuming the king operates like most corporations, whom will he appoint? The first adviser’s proposal is physically impossible, no matter what resources are put to the task. The second adviser strikes the king as too cautious. The third adviser gets the job, because he is proposing an aggressive schedule  that is not impossible. The adviser knows the deadline won’t be met, but he can deal with that later. The king knows it  too, but is betting that the adviser will redouble his efforts to atone for his failure to deliver on time. Four years and eleven months later, a prince is born.

In this kind of situation, the task durations used in project planning are the shortest that don’t violate the laws of physics. The project managers make the sale on that basis, miss the deadlines, and work desperately hard to finish. As a result of surviving in this game, they are promoted and continue the same practices with the next generation.

The game does not have to be played this way, but the initiative must come from the top. Soichiro Honda set a different tone early in the development of his company, by engaging it in motorcycle racing. When participating in a race, nothing else matters if the vehicle, pilot, pit crew and supplies are not in place and ready at the start of the race. Such hard deadlines are also found in organizing concerts, preparing museum exhibitions, or launching a space probe to fly by multiple planets. They focus project teams on realism in task assessment and creativity in dealing with the unexpected. Besides the publicity, Soichiro Honda’s purpose was to infuse all the company’s projects with the “racing spirit.”

There are, of course, many other useful perspectives on project management, and I find that the most interesting to read are case studies. Following are some of my favorites:

  • The soul of a new machine, This is Tracy Kidder’s account of the development of the MV-8000 computer at Data General in 1980. The technology is irrelevant today but the human dynamics have not changed. The now defunct Data General computer company  had been caught by surprise by DEC’s introduction of the VAX in 1978 and needed a response. The book has all the elements of a thriller: an inept corporate bureaucracy squandering millions on a luxurious research facility for no return, while a small band of rebels in the cellar of an old building succeeds against the odds in developing the product that gave the company a new lease on life.
  • Car, by Mary Walton, Like, “The soul of a new machine,” this is a product development case study – if the 1996 Taurus at Ford – by a journalist who was invited to follow it from start to finish. The most interesting aspect of this case is that, while the development project was technically successful, the resulting product did not keep its promises in the market.
  • Fred Moody’s I sing the body electronic is similar to the other books, but about software product development at Microsoft in the 1990s.
  • Stephen Ambrose’s Nothing Like It in the World takes you into 19th century project management on the transcontinental railroad.
  • A Man, a Plan, a Canal – Panama, a DVD narrated by David McCullough about the mother of all civil engineering projects. Note that the title is a palindrome.

Tom DeMarco’s The Deadline is not a case study but a novel about project management. It is about software development but is entertaining and enlightening even for readers in other fields. DeMarco is a deep and original thinker, but with the wit of a Tom Wolfe.
