Return to Flight Task Group biographies

Here are the biographies of those on the Return to Flight Task Group who saw the NASA engineering by PowerPoint and denounced it in their final report (quoted extensively in the last 2 pages of my essay).

As I wrote in the essay above, "Both the Columbia Accident Accident Investigation Board (2003) and the Return to Flight Task Group (2005) were filled with smart experienced people with spectacular credentials. These review boards examined what is probably the best evidence available on PP for technical work: hundreds of PP decks from a high-IQ government agency thorough practiced in PP. Both review boards concluded that (1) PP is an inappropriate tool for engineering reports, presentations, documentation; and (2) the technical report is superior to PP. Matched up against alternative tools, PowerPoint loses."

Here are the biographies of the NASA PowerPoint critics:

Elizabeth Lane Lawley, a professor visiting Microsoft, comments on "the culture of the deck."

There are many things I've been delighted and impressed by during the nearly five months I've now spent at Microsoft. However, there have also been a few things that i've found extraordinarily disheartening. One of the latter has been the organizatational dependence on "the deck" (that is, Powerpoint files) as the standard mechanism for conveying nearly all information.

Tonight I was reading through one of the blogs I've recently added to my aggregator, the most-excellent Presentation Zen (by Garr Reynolds), and I came across a post entitled "The sound of one room napping." It included this wonderful passage, which sums up beautifully what I've been trying to say to the people around me at Microsoft:

Attempting to have slides serve both as projected visuals and as stand-alone handouts makes for bad visuals and bad documentation. Yet, this is a typical, acceptable approach. PowerPoint (or Keynote) is a tool for displaying visual information, information that helps you tell your story, make your case, or prove your point. PowerPoint is a terrible tool for making written documents, that's what word processors are for.

Why don't conference organizers request that speakers instead send a written document that covers the main points of their presentation with appropriate detail and depth? A Word or PDF document that is written in a concise and readable fashion with a bibliography and links to even more detail, for those who are interested, would be far more effective. When I get back home from the conference, do organizers really think I'm going to "read" pages full of PowerPoint slides? One does not read a printout of someone's two-month old PowerPoint slides, one guesses, decodes, and attempts to glean meaning from the series of low-resolution titles, bullets, charts, and clipart. At least they do that for a while...until they give up. With a written document, however, there is no reason for shallowness or ambiguity (assuming one writes well).

To be different and effective, use a well-written, detailed document for your handout and well-designed, simple, intelligent graphics for your visuals. Now that would be atypical.

I wish there was some way to make this (and Tufte's The Cognitive Style of Powerpoint, and Atkinson's Beyond Bullet Points) required reading for every Microsoft employee.

Her experience at Microsoft is comparable to that of the NASA Return to Flight Task Group with regard to the persistent disutility of using PP decks to replace technical reports.

ET helps NASA with Probability Risk Assessments (PRA), for upcoming launch

Here is a link to William Harwood's excellent account of shuttle risks in the upcoming flight, scheduled for this Saturday, context for my comments that follow.

About 18 months ago in Houston I reviewed the shuttle Probability Risk Assessment (PRA) material for NASA. PRA works with a list of possible threats, estimates their probablilities and expected losses, and then seeks to assist decision-making for shuttle risk-reduction.

After the PRA group presented their results, I had two major suggestions:

(1) They should prepare a detailed summary matrix (on, of course, 11" by 17" paper), ordering the risks and providing, in a comments column, relevant background for each estimate. Let that intense matrix, backed up by similar more-detailed 11" by 17" arrays of risk estimates, be the main presentation device and analytical tool for making decisions. This was designed to replace their chippy and twiddly PP slides, which made a hash of their good technical work and made it difficult to assess the overall risk context.

(2) The PRA assessments did not take into account a major risk factor in both the Challenger and Columbia accidents: on-ground intellectual failures in engineering analysis. In the case of the Challenger, the analytic process on the day before the accident was seriously deficient, in the sense that--in hindsight to be sure--the Challenger would not have been launched on that very cold day (which compromised the O-rings and caused the accident) if smarter engineering analysis and better decision-making had taken place. In the case of the Columbia, better analysis and decision-making during the flight might have yielded rescue efforts to try to save the crew, which was endangered by damage to the Columbia suffered at launch. I suggested to the PRA group that on-ground analytic problems contributed to something like 1.3 of the 2.0 accidents in the 113 flights. But there was no risk assessment of such in the PRA; that is, about 65% of the directly observed empirical risk in the 113 flights was not accounted for by the PRA model. The shuttle itself was considerably less risky than what was happening on the ground in decision-making about the shuttle.

At the meeting, I also handed out Richard Feynman's famous discussion of shuttle risks, which Feynman prepared as a part of the Challenger investigation in 1987.

The analysis for the upcoming launch of the Discovery in July 2006, as the link above indicates, was an intense evaluation of risks and trade-offs.

On the basis of reading some of the public documentation (and no direct knowledge) for the upcoming flight in the last few weeks, I think that NASA has made a reasonable and well-informed decision for the upcoming flight. It was also a contested decision. I would vote for the launch. The on-ground factors that contributed to 1.3 shuttle losses appear to be mitigated by the thorough analysis for this flight. The current risk number is a cloudy 1 in 100, which is risky but has been acceptable in the past. The cloudy contributions to risk are the recent changes in the foam, which turns Discovery into something of an experiment.

In the Discovery discussions, a telling distinction was made between "programmatic risks" and "crew risks." The programmatic risk is very high right now no matter what happens. Having flown once in 3+ years, the shuttle program might well collapse if unable to fly soon (within a year or so), or if there is another accident even if the crew escaped unharmed. This rescue scenario is itself troublesome, since the rescue launch must quickly take into account what caused the need for the Discovery crew-rescue in the first place.

Here is the PP deck for "STS-121, Flight Readiness Review, External Tank Project (ET-119)."

(This pdf file should be up in a separate window to read in parallel with the comments below.)

These slides summarize the results of the enormous amount of resources (probably >$1 billion, some estimates are much higher) devoted to the external tank foam problem.

The slides do not display a sense of engineering intelligence or discipline. In the main report, there is a persistent habit of dequantification and a general absence of units of measurement. The back-up slides are more quantified and at a higher intellectual level. Several of the slides look like they were produced by a designer lacking in scientific training.

The key overview slide (page 3) is a very good idea but a presentation mess. The good idea is to have an intense and fairly detailed summary early in the presentation. But PP's lightweight resolution and lousy design tools compromise the summary slide. Students of PP design might, however, appreciate the 5 sets of orange drop-shadows, 4 wavy-purple color fields, 3 unintentionally 3D blue time-lines, 2 overactive grids, and floating-off-in-space bullets in the highlight box (with an arbitrary change from dots to dashes midstream in the box). All this stuff on one over-produced but importantslide.

In real science, every photograph has a scale of measurement built right in to the photograph. This low-resolution display method makes it impossible to do so. (Even the shuttle close-out photos, just about the most documentary type of photographs one can imagine, have no scales of measurement and no rulers in the pictures.)

The bullet lists tend somewhat to be base-touching grunts, which show effects without causes, actions without actors, verbs without subjects, and nouns without predicates. The branding with 3 logos on every slide (the title slide has 4 logos) is unprofessional, pitchy, turfy. Are we doing engineering analysis or marketing here? Some 20% of the space of every slide (already a a very low resolution display method) is devoted to branding and to the boxed-in awkward and repetitive slide titles. It is as if each and every slide has to remind the viewer what the presentation is about. So the top 20% of every slide is something to skip, perhaps putting some viewers in the mode of skipping and sliding through the rest of the slide. It is as if the top of every slide announces "nothing important here, you've seen it all many times before."

In several slides, the visually most active materials are the cross-hatched exploding 3D arrows linking the external tank to the magnified areas. Why are the arrows pointing anyway? It's just a simple linking line. The idea here of close contextualized imaging of the problem areas is a very good one, but the badly-drawn giant blue arrows are silly, and result in making the dequantified images of the foam problem areas too small.

The typography is poor, with odd hierarchies (underlined bold italic in parentheses at one point). Is "O2" the proper way for NASA contractors and NASA to write the oxygen molecule (even wikipedia uses a subscript)? Does the slide designer know how to write a subscript in PP?

The overlapping statistical graphics on page BU-2 are presented as decoration, not evidence.

The report is 33 slides long; yet about 10 slide-equivalents are essentially content-free (compulsive repetitive branding, twiddly hierarchical organization, empty space, assorted title pages, and so on). This PP fluffed-up material here and quite a bit more could easily be placed in a technical report on 4 pages of an 11" by 17" piece of paper (folded in half), an exercise left to the student.

The tone and style of the presentation seem alienated from professional engineering. It looks like the slides were prepared by a PP designer, assisted now and then by an engineer. Or maybe it is just the PP pitch style diluting the content. At an FRR?!

I hope the actual engineering for the shuttle is a lot better than the evidence for the engineering shown in this presentation.

How much does a problematic presentational style signal poor engineering? Is it just PP or a PP designer weakening the quality of evidence? Or are there deeper intellectual failures? The dequantification, the failure to follow professional engineering conventions, the infomercial tone are worrisome. There is no sign of engineering discipline here, except in the back-up slides. Thus the effect of the presentation is to suggest that there just might be some problems with foam engineering and analytical quality. A danger of problematic presentational styles, such as NASA PP, is not only that they enable sloppiness but also that they can place the truth in disrepute.

It is also a shame that all that expensive engineering work winds up being represented in this manner at a Flight Readiness Review.

Response to PowerPoint Does Rocket Science (and the upcoming Discovery flight)

Did the news conference present the PP slides, or did they a different medium to convey the details?

-- Allan T. Grohe Jr. (email)

They usually give a brief talk and then answer questions in a straightforward and intelligent manner, accompanied by occasional physical props, such as the broken-off piece of foam or model of the external tank. They did not use PP in the 8 to 10 press conferences I've viewed. You can see the press conferences and the launch by going to NASA TV.

Apparently the PP Flight Readiness Review for the foam (reviewed above) was something of a leak; the other FRRs at the meeting are not going to be made available. Keith Cowing, who runs NASA Watch, sent me an email saying that I might be interested in the foam FRR that he had posted at his website. You can see more on this at NASA Watch.

I think the press conferences are excellent, assisted by a well-informed space press. After the flight, the head of NASA Michael Griffin was asked at the press conference if he felt "vindicated" by his decision to launch. He said not at all, if anything, it was vindication for the scientific method--that is, looking at the evidence and the numbers at hand. What a wonderful thing for the Director of NASA to say. This contrasts to the PP cognitive style, which often seems to encourage presenters to pitch rather than present evidence.

-- Edward Tufte

Below, a link to a good account of the Discovery inspections by John Schwartz of the New York Times on the problem of distinguishing useful evidence from additional evidence, a problem that also occurs with newly developed exquisitely sensitive measurements (for example, PSA tests and the monitoring of contaminants of drinking water).

John Schwartz, New Scrutiny for Every Speck on the Shuttle, New York Times, 11 July 2006

Is the space shuttle Discovery safe to re-enter the atmosphere on its way to landing next Monday?

Determining that it is, as the National Aeronautics and Space Administration did on Sunday, is an arduous process. Even though engineers and analysts say there is really no choice for an agency still climbing back from a horrendous re-entry accident -- the loss of the shuttle Columbia and its crew of seven on a bright February morning in 2003 -- the level of detail can sometimes seem absurd.

Blame the tools that have been developed since the Columbia disaster. They give such stunningly clear and detailed images of the shuttle from orbit that there are endless new problems to worry about.

On Sunday, mission managers announced results of their close look at every suspicious mark and irregularity on the shuttle surface, including stiff bits of cloth called gap fillers that were poking out of the underbelly, as well as loosened patches on insulating blankets.

Before the Columbia, such problems would have probably not been noticed. Now, each becomes a potentially troubling issue, to be dealt with one by one by one by one. On Sunday, the sixth day of the 13-day flight, Steve Poulos, the orbiter projects office manager, said every item had finally been checked off.

These issues can lead to quite subtle consequences, as my Yale colleague Alvan R. Feinstein suggested in many studies, including this one in the Archives of Internal Medicine:

. . . many breast cancers found by mammography screening have excellent prognosis not just because of early detection, but also because many of the cancers are relatively benign, requiring minimal therapy.

from Sandra Y. Moody-Ayers, MD; Carolyn K. Wells, MPH; Alvan R. Feinstein, MD, MS, "Benign" Tumors and "Early Detection" in Mammography-Screened Patients of a Natural Cohort With Breast Cancer, Arch Intern Med. 2000; 160: 1109-1115.

In your workshops, you describe how to replace PowerPoint presentations with 11 x 17 sized reports, and provide many good arguments for why "engineering by PowerPoint" doesn't work very well.

This website that might interest you and your audience. It describes a process for creating A3 sized technical reports, and using them to make better decisions.

Dr. Durward Sobek of Montana State University spent six months in Japan as a grad student, interviewing and observing Toyota engineers to uncover the reasons why Toyota was able to develop cars much more quickly than other auto makers and also maintain high standards for reliability.

Toyota uses these A3 reports extensively in their engineering processes. They believe that the discipline required to accurately capture a problem on a single sheet forces the author to express the issue with both clarity and conciseness. They emphasize using visual models to express ideas rather than a lot of text, and value the ability to have all of the pertinent information within a single field of vision. The engineers are also required to bring their supporting documentation, so that the team can dive into the details when necessary.

Since then, Dr. Sobek has taught many engineers how to use A3 reports to make better technical decisions. I can tell you from my personal experience with this technique that it is amazingly powerful. By using one of these reports, we solved a technical problem within a single meeting that we had literally wrestled with for years through engineering by PowerPoint. By forcing us to make our knowledge about the problem visible in a systematic way, the tool helped us come to a deeper understanding that led to the solution.

-- Katherine Radeka (email)

The "A3 Process" described above begins with a good idea and then dilutes it into a Business Methodology Fad. BMFs are characterized by a germ of a good idea, but also by over-reaching, over-simplifying, excessive focus on a single idea, pitchy and enthusiastic over-simplified examples, and pretentious names ("The Toyota Method," "The Long Tail,", "The Genghis Khan Guide to Mastering the Universe," "The Takahari Guide to Infinite Profits," and so on).

In the Beautiful Evidence chapter on corrupt techniques in evidence presentations, the section on over-reaching concludes with this: "When a precise, narrowly focused technical idea becomes metaphor and sprawls globally, its credibility must be earned afresh locally by means of specific evidence demonstrating the relevance and explanatory power of the idea in its new application." (p. 151)

The A3 method, which at its heart is a good idea, requires some down-in-the-trenches detailed and complex examples. And it should avoid bullet lists in describing the method.

PPT and Military Intelligence

Central Command Charts Sharp Movement of the Civil Conflict in Iraq Toward Chaos, by Michael Gordon in the New York Times, Nov. 1, 2006.

Here are some preliminary comments on the slide "Iraq: I&W of Civil Conflict."

It appears that "I&W" means "Indications and Warnings." Replacing the acronym in the slide title does pep up meaning to outsiders: "Iraq: Indications and Warnings of Civil Conflict," but maybe it wouldn't fit on the slide.

Only this single slide was leaked (by the military? by DoD?), and so maybe some of the analytical problems are better handled on accompanying slides. Maybe.

Doing competent political analysis, epidemiology, nation-building, and war planning (all of which they're trying to do) in a chaotic situation is impossible, and not much good social science and epidemiology can be expected in chaos and from a military entangled in Iraq. In real-time chaotic situations, the data-collection is going to be sloppy because people have more important things to do. (Recall, for example, the gross errors in counts of 9/11 deaths, as the count went from 6,000 to 2,800 in a few weeks.) And what's taking place is in profoundly different cultures and in different languages from those of the non-local military in Iraq. But sloppy data does not justify analytical sloppiness in reporting. In fact, sloppy data requires greater analytical precision of thought.

The slide reports performance data--a list of phrases, with each phrase accompanied by a measure of performance. This is what the tables in the sports section, mutual fund page, and weather page of newspapers do very well. Those designs are much better for reporting performance data than the slide format here. In sports and stock market tables, each phrase is accompanied by multiple measures of performance, often over varying time-periods. All that won't fit on the slide; this suggests that we should use better reporting method than PP, instead of abbreviating the evidence to fit the slide. As the millions of readers of sports tables each day demonstrate, people can easily manage large tables of information. Thus those being briefed in the military should ask: Why are our presentations operating at 2% of the data richness of routine tables found in the sports section? Let the viewers read and explore through a range of material; different eyes will search for different things in the evidence. The metaphor should be the cognitive style of the sports section (or weather or financial newspaper pages) not the cognitive style of PowerPoint.

There is no cloud of uncertainty or error history associated with the editorializing color. At times, such color codings suggest an excess of certainty.

The Iraq slide above provides some relevant but thin and overly short-run time-comparisons: 2 arrows on the left showing "change since last week," and the "Index of Civil Conflict (Assessed)", which sort of compares "Pre- Samarra" with "Last week" and "Current". And there's a potent time-comparison in words: ". . . violence at all-time high, spreading geographically."

To get more time comparisons on the 14 "Reads" and "Additional Indicators," 14 sparkline time-line histories for the last year (week by week, if available) would be useful as a overall but detailed summary. This would reduce the snapshot tone of the 14 reads and indicators. In our thread Sparklines: theory and practice, there are (at the top of the thread) data tables with sparklines that report daily and longterm financial data; one such table shows 14,000 numbers, many of them accurate to only 2 digits (not much for financial data) under the philosophy of "Try to be approximately right rather than exactly wrong." The short-run weekly jitters and non-reports need to be smoothed out to see (and compare with)the long-run trends. Weekly data cooperate with the notorious recency bias, whereby way too much weight is given to the most recent piece of data, just because it is recent. These weekly reports should be in the context of longer run information to reduce the chances that analysis will be dancing around only with today's news.

The list style, surely one damn thing after another here, is merely descriptive and thus preliminary to policy analysis. That analysis might have been done on the other slides or maybe this report is merely meant as a scorecard. If it is a scorecard, it is grossly impoverished compared to sports, weather, and financial tables.

The current fashion (it, too, shall pass) in government is the stoplight style (green, yellow, red), which tends to dequantify data. With categories of this sort, there's always a concern with how the breaks among categories are chosen and with the meanings of the categories. It will often be better to provide some evidence or numbers, and then a separate editorial-judgmental color about the number.

The slide contains odd uses of the color-words: for example, a green dot indicating "routine" next to the exciting phrase "unorganized spontaneous mass civil conflict". Shouldn't "routine unorganized spontaneous mass civil conflict" be red-critical? After Hiroshima, would Nagasaki get the routine green dot for nothing different than what happened three days earlier? It looks like weekly wiggles get too much attention, and longrun levels of seriousness too little attention on this slide, as chaos becomes routine week by week and bit by bit. Monthly rather then the sketchy weekly reports might be better for policy analysis. Or at least provide a monthly aggregations over a period of many months (even the entire war) in a scorecard along with the weekly incidents.

The leaking of the slide makes a point about the differences between the government's secret analysis and the public reports by the Administration, a common theme of the insider books on Iraq policy-making (most recently Colin Powell's book). At some time, "reality must take precedence over public relations," as Richard Feynman remarked about the shuttle Challenger accident.

A good many comments by our contributors are on-point but are not taken into account here.

Note the measurements, definitions, and comparisons to standards in the customer scorecard in the "Report of the South Central Connecticut Regional Water Authority" (above).

Finally, the over-riding metaphor of all this--"the war on terror"--is a big conceptual problem. Once it's a war, then it almost necessarily invokes large-scale military action and searching for a locale (some place, any place, Iraq) for large-scale military action. But terrorists are more like the Mafia or gangs than they are like armies. Perhaps a better metaphor is that terrorism is largely a law-enforcement problem (requiring focused and clandestine local action, informants, endless detective work, detailed knowledge of the local languages and cultures).

Among the grand truths about human behavior, surely the principles of "the unintended consequences of purposive social action" and "it's more complicated than that" are among the top five. Sometimes unintended consequences are largely virtuous or benign (as in market allocation of goods and services if externalities are mitigated) and sometimes the unintended consequences are appalling. That's because it's more complicated than that.

PowerPoint does blackholes?

John Wheeler, eminent physicist, died in 2008 at the age of 96. To commemorate his contributions to physics, astronomy, cosmology, quantum mechanics and more, the April 2009 issue of Physics Today contains several wonderful articles about Wheeler.

The article, "John Wheeler, relativity, and quantum information", by his former-students Misner, Thorne and Zurek (all prominent physicists themselves, now) contains this photograph taken by Kip Thorne. The caption reads, "John Wheeler lecturing at a conference in Cambridge, UK, in 1971. Wheeler's style was to cover the blackboard with inspirational colored-chalk diagrams and phrases before the lecture, then work his way through them, one by one."

The blackboard looks like a precursor to today's PowerPoint presentation, but not poor PowerPoint full of bullet grunts. Instead, a sequence of diagrams and key phrases to guide the audience, and the speaker, through the material. Judging from the photo, this must have been quite the lecture.

PowerPoint and scientific fraud

From the Wall Street Journal blog, July 14, 2009:

Q&A: What PowerPoint Has to Do With Scientific Fraud

"The oversight [of scientific data] is now vastly diminished. Even within the laboratory environment, many students and post-docs and scientists are not showing raw data anymore. They're showing PowerPoint presentations. That gives the individual, if they're so inclined, the ability to manipulate data right up-front. Unless a mentor is vigilant, there's a real breakdown."

I took Presenting Data and Information a few years ago in Boston while at another company, but ET's influence has stuck with me.

In my first year at my new employer, I can confidently credit the course with my win of an Individual Achievement Award in recognition of my technical analysis briefings of a systems performance problem which I resolved, as well as my recent win of my company's 2009 Information Systems Excellence Award in the Innovation category.

My "Quick Start Guide" for the roll-out of a crucial new capability in the network was designed and built by the book (the Tufte Book) - on an 11x17 folded sheet, multiple columns with embedded illustrations, plus full bleed thanks to the commendable graphic design and printing services staff - and it was a resounding, dazzling success. It turned heads all the way up the chain of command, and was received with delight by the users.

I was enthusiastically told by an IS department leader that nothing of the kind had ever been seen before in any other rollout in IS, and it represented just the kind of thing that our department should be doing more of. I and my colleagues stood ready on rollout day for questions and problems, but heard only the faint hum of heightened productivity.

While I fortunately didn't have to cope with the mechanics of the layout in Quark Express, I was also fortunate to be working with a designer with whom I could be specific and detailed in my vision of the final document, as I referred to my PD&I notes and materials.

My users found it helpful that I prepared two PDF versions of the document for the eRoom document archive - one as the original two-page 11x17 format, and the other a four-page letter-size version to permit people without access to a large-format printer to produce a copy of the document, single- or double-sided.

"'PowerPoint makes us stupid,' Gen. James N. Mattis of the Marine Corps, the Joint Forces commander, said this month at a military conference in North Carolina." From the New York Times:

We Have Met the Enemy and He Is PowerPoint

WASHINGTON -- Gen. Stanley A. McChrystal, the leader of American and NATO forces in Afghanistan, was shown a PowerPoint slide in Kabul last summer that was meant to portray the complexity of American military strategy, but looked more like a bowl of spaghetti.

Powerpoint spaghetti slide

"When we understand that slide, we'll have won the war," General McChrystal dryly remarked, one of his advisers recalled, as the room erupted in laughter.

The slide has since bounced around the Internet as an example of a military tool that has spun out of control. Like an insurgency, PowerPoint has crept into the daily lives of military commanders and reached the level of near obsession. The amount of time expended on PowerPoint, the Microsoft presentation program of computer-generated charts, graphs and bullet points, has made it a running joke in the Pentagon and in Iraq and Afghanistan.

"PowerPoint makes us stupid," Gen. James N. Mattis of the Marine Corps, the Joint Forces commander, said this month at a military conference in North Carolina. (He spoke without PowerPoint.) Brig. Gen. H. R. McMaster, who banned PowerPoint presentations when he led the successful effort to secure the northern Iraqi city of Tal Afar in 2005, followed up at the same conference by likening PowerPoint to an internal threat.

"It's dangerous because it can create the illusion of understanding and the illusion of control," General McMaster said in a telephone interview afterward. "Some problems in the world are not bullet-izable."

In General McMaster's view, PowerPoint's worst offense is not a chart like the spaghetti graphic, which was first uncovered by NBC's Richard Engel, but rigid lists of bullet points (in, say, a presentation on a conflict's causes) that take no account of interconnected political, economic and ethnic forces. "If you divorce war from all of that, it becomes a targeting exercise," General McMaster said.

Commanders say that behind all the PowerPoint jokes are serious concerns that the program stifles discussion, critical thinking and thoughtful decision-making. Not least, it ties up junior officers -- referred to as PowerPoint Rangers -- in the daily preparation of slides, be it for a Joint Staff meeting in Washington or for a platoon leader's pre-mission combat briefing in a remote pocket of Afghanistan.

Last year when a military Web site, Company Command, asked an Army platoon leader in Iraq, Lt. Sam Nuxoll, how he spent most of his time, he responded, "Making PowerPoint slides." When pressed, he said he was serious.

"I have to make a storyboard complete with digital pictures, diagrams and text summaries on just about anything that happens," Lieutenant Nuxoll told the Web site. "Conduct a key leader engagement? Make a storyboard. Award a microgrant? Make a storyboard."

Despite such tales, "death by PowerPoint," the phrase used to described the numbing sensation that accompanies a 30-slide briefing, seems here to stay. The program, which first went on sale in 1987 and was acquired by Microsoft soon afterward, is deeply embedded in a military culture that has come to rely on PowerPoint's hierarchical ordering of a confused world.
