Crisis in Outer Space! (The True Story of Apollo 13)


My 26th book will be Project: Impossible, an exploration of how people achieved goals any reasonable person would have thought impossible. This week, the true story of the the Apollo 13 mission, continuing last week’s brief history of rocketry and spaceflight. 


Thirteen

Although the United States officially “won” the space race with Apollo 11 on July 20, 1969, there would be five more missions to the Moon, during four of which astronauts walked on the lunar surface. The exception was Apollo 13, the seventh manned mission in the program.

Gordon Cooper and Donn Eisele, originally scheduled for Apollo 13, were passed over by NASA management. The flight crew operations chief selected Alan Shepard, the first American in space, to replace Cooper, but management turned him down because of recent surgery. As a result, NASA selected the backup crew for Apollo 11, who were scheduled for Apollo 14, for this mission. Jim Lovell, who had flown on two Gemini missions and one previous Apollo mission, was to be the mission commander. Fred Haise, a research test pilot, had been on two previous backup crews but had never flown in space. The command module pilot, who would stay in orbit while the other two crew members went down to the lunar surface, was Ken Mattingly. It would also be his first time in space.

Seven days before launch, Mattingly was exposed to measles (as it turned out, he didn’t get them), and was replaced by Jack Swigert from the backup team. It would also be Swigert’s first time in space.

The lead flight director, in overall command, was Gene Kranz.

Crisis in Outer Space

Liftoff for the Apollo 13 mission came on April 11, 1970, at 13:13 Central Standard Time. There was a small hiccup during the launch: the center engine in the second stage had to be shut down early because of a malfunction known as “pogo oscillation.” It had been seen in previous missions, but never so seriously. Automatic cut-offs stopped the problem before it could tear the ship apart; later missions had technical modifications to prevent a reoccurrence. In any event, the remaining engines burned longer, and the vehicle continued to a successful orbit.

Such a problem was hardly unusual. Given the complexity and inherent risk of any space mission, it would have been far more notable had the flight gone off without a hitch. Solving problems was all in a day’s work for NASA’s talented and experienced people.

But what happened next tested their capabilities to the maximum.

About 56 hours after takeoff, with Apollo 13 much closer to the Moon than to the Earth, Mission Control radioed Jack Swigert and asked him to turn on the stirring fans for the hydrogen and oxygen tanks. About a minute and a half later, there was a loud bang. The crew’s first thought was that the lunar module had been struck by a meteoroid.

What had happened was actually much worse. Number 2 oxygen tank had exploded. Later analysis would reveal damaged insulation on the wires to the stirring fan, allowing a short circuit. A large aluminum skin panel on the outside of the ship blew off, damaging an antenna and momentarily interrupting communication with Mission Control. The shock of the explosion caused a break in the number 1 oxygen tank as well. Over the next two hours, the entire oxygen supply of the service module was lost. Complicating matters even more, the fuel cells needed oxygen and hydrogen to generate electricity. The command module was left with backup battery power only.

The damaged Apollo 13 spacecraft


Landing on the Moon was no longer an option. The crew hastily shut down the command module to save its limited power and moved into the lunar module. The new project was how to get the crew back safely to Earth.

What saved the Apollo 13 mission?

The Kranz Dictum

It’s only in the movie version of Apollo 13 that Gene Kranz says the phrase, “Failure is not an option.” The real message came after the 1967 Apollo 1 disaster, in which astronauts Virgin “Gus” Grissom, Edward H. White, and Roger B. Chaffee lost their lives, Gene Krantz addressed his flight control team, establishing what would become known as “The Kranz Dictum.”
Spaceflight will never tolerate carelessness, incapacity, and neglect. Somewhere, somehow, we screwed up. It could have been in design, build, or test. Whatever it was, we should have caught it. 
We were too gung ho about the schedule and we locked out all of the problems we saw each day in our work. Every element of the program was in trouble and so were we. The simulators were not working, Mission Control was behind in virtually every area, and the flight and test procedures changed daily. Nothing we did had any shelf life. Not one of us stood up and said, “Dammit, stop!”
I don't know what Thompson's committee will find as the cause, but I know what I find. We are the cause! We were not ready! We did not do our job. We were rolling the dice, hoping that things would come together by launch day, when in our hearts we knew it would take a miracle. We were pushing the schedule and betting that the Cape would slip before we did. 
 
From this day forward, Flight Control will be known by two words: “Tough and Competent.” Tough means we are forever accountable for what we do or what we fail to do. We will never again compromise our responsibilities. Every time we walk into Mission Control we will know what we stand for. 
Competent means we will never take anything for granted. We will never be found short in our knowledge and in our skills. Mission Control will be perfect. 
 
When you leave this meeting today you will go to your office and the first thing you will do there is to write “Tough and Competent” on your blackboards. It will never be erased. Each day when you enter the room these words will remind you of the price paid by Grissom, White, and Chaffee. These words are the price of admission to the ranks of Mission Control.

The Apollo flight teams had prepared for disaster time and time again. Exercises, simulations, and extensive training all went into achieving the goal of “tough and competent.” This is an essential ingredient in effective crisis management. By preparing for different eventualities and maintaining a high level of readiness, you and your team are in the best possible position to handle a crisis.

However, no matter how good you are, failure is always an option.


Timeline of the events in the Apollo 13 crisis


Working the Problems

Crises differ from more general projects in several ways. First, they are often imposed on the project team with little or no notice. Apollo 13 was going well until suddenly it wasn’t. Crises normally have extreme constraints in time and resources. The clock was ticking with Apollo 13. If problems could not be solved in very short order, the consequences would take hold at once — with fatal results.

While NASA had an extensive supply of spare parts, machine shops, and trained engineers who could have fixed the ship easily, those resources were on Earth, and the problem was more than a hundred thousand miles away.

Evacuating and shutting down the command module was the first order of business, but there were many obstacles yet to be overcome before the crew of Apollo 13 would once again see home. There were plans for aborting an Apollo mission, but some of them were ruled out by the exigencies of the situation. The quickest way home required jettisoning the lunar module, but that was serving as the lifeboat for the crew. The service module integrity was in doubt, so they didn’t want to fire its engine except as a last resort.

That left a circumlunar option, using the Moon’s gravity as a slingshot to send the crippled ship back toward earth. To do that, they needed to make a minor course correction, but debris from the explosion made it impossible to use the onboard sextant device, requiring Jim Lovell to fly the spacecraft using the sun in the cockpit window as an alignment star.

The problems mounted. While there was plenty of oxygen in the lunar module, carbon dioxide removal required the use of lithium hydroxide canisters. While there were enough of them available, the square command module canisters wouldn’t fit in the round LM openings. An engineering team created a kludged-together system using plastic bags, cardboard, and tape, working on an extremely limited time span.

(As an aside, the duct tape and other supplies that made this possible were also part of planning for crisis management: there was a kit containing some basic utility items available for use. One can only imagine the planning that went into deciding exactly what would be part of that kit.)

Power supplies were limited. The LM was rated for two people for a day and a half, and now it would need to accommodate three people for four days. All nonessential power was shut down. Water and food were limited. The crew became dehydrated. Lovell lost 14 pounds.

The team managed to overcome one problem after another, but the toughest technical challenge came at the end of the mission. There had never been a case where the command module had to be powered up after a long sleep, and the flight controllers had to test and write new procedures to accomplish it. (In the movie, that’s the suspenseful scene in which Ken Mattingly, played by Gary Sinise, tries to find a start-up sequence that draws less than 20 watts.) The normal time for a project like that was three months; the team had three days.

By the time the Apollo 13 team reentered the command module, condensation had covered the interior with fine droplets of water. Water was inside the circuit panels as well, and the chance of a short circuit was all too real. Fortunately, the tragedy of Apollo 1 had led to various safeguards against short circuits; there was no problem.

Four hours before landing, the crew jettisoned the service module, and one hour before landing they jettisoned the LM that had served as their lifeboat. As they entered the atmosphere, the heat of reentry created rain inside the command module.

But that was the final hazard.

On April 17, 1970, Apollo 13 splashed down safely near American Samoa.

Crisis Management and the Impossible Project

What distinguishes a crisis from other kinds of projects is the way it tightens the constraints. Time pressure is normally high, and the nature of the situation normally limits resources that would otherwise be available to the team. These revised constraints are normally established by the situation, not by the will or desire of the project team. In the case of Apollo 13, a procedure that would normally take three months had to be developed in three days, for the simple reason that three days was all they had. Modifying the carbon dioxide removal system would have been trivial on Earth; it was a nail-biting project in space, with only the resources available on the ship able to be used for the job.

Had the mission control team not been well prepared — had Gene Kranz not insisted on “tough and competent” — had simulations by the hundreds not taken place, it’s almost certain that the Apollo 13 mission would have ended in failure.

But that’s the point. To prepare for crisis, prepare early.

By the time the crisis occurs, it’s usually too late.

A Brief History of Rocketry and Spaceflight


Robert Goddard and his rocket

My 26th book will be Project: Impossible, an exploration of how people achieved goals any reasonable person would have thought impossible. This week, a brief history of rocketry and spaceflight.

Mercury astronaut John Glenn, asked how he felt during his three-orbit flight, is reputed to have replied, “As I hurtled through space, one thought kept crossing my mind: Every part of this capsule was supplied by the lowest bidder.”

The history of rocketry and spaceflight is also a history of risk-taking and risk management. New technology is inherently unstable, a product of its newness, and when you are using that technology to propel people into previously unexplored conditions, disaster is never more than a small step away.

To China…and Beyond!

The history of rocketry traces back to ancient China. Gunpowder, a Chinese invention of the 9th century CE, was a byproduct of the alchemical search for the elixir of life, and as is the case with so many discoveries, its accidental secondary uses turned out to be far more important than the original inventor’s intent.

Rockets were first used in fireworks displays, and only entered the battlefield in 1232 CE against the Mongol invasion. The Chinese even invented multi-stage rocketry by the mid 14th century, by which time the technology had spread to India, the Middle East and eventually to Europe. The "rockets’ red glare" appear in American history during the War of 1812 and in the US national anthem "The Star-Spangled Banner."

According to legend, during the Ming Dynasty, a minor court official named 萬虎 (Wan Hu) attempted to become an astronaut by flying a chair with 47 rockets attached. He was never seen again.

In 1633, again according to legend, Lagâri Hasan Çelebi of the Ottoman Empire made a successful rocket flight to a height of 300 meters. His words before takeoff were, “O my sultan! Be blessed, I am going to talk to Jesus!” Upon landing, he told the sultan, “Jesus sends his regards to you.”

Somewhat better sourced are the achievements of car designer Fritz von Opel, who in the 1920s built a series of rocket-powered cars and a rocket-powered glider. One of his cars reached a speed of 254 km/h (157 mph). The rocket-powered glider was less successful: it exploded on its second test flight.

Modern rocketry owes its start to high school mathematics teacher Konstantin Eduardovich Tsiolkovsky, who worked in the final years of the 19th century and the first years of the 20th. Inspired by Jules Verne, Tsiolkovsky developed a philosophy of space travel as a means for perfecting the human race, and in the process worked out most of the formulas at the heart of modern rocketry, including the famous Tsiolkovsky rocket equation.

Beginning in 1912, the American Robert Goddard established that a rocket would work in a vacuum and proposed sending a solid-fuel rocket to the moon, an idea ridiculed by the New York Times in an editorial. Goddard launched the first liquid-fueled rocket in 1926.

A young member of the Verein für Raumschiffahrt (German Rocket Society) named Werner von Braun developed long-range military rockets for the Wehrmacht, including the V-1 and the V-2. The Messerschmitt Me 163 Komet, was the war’s only operational rocket-powered fighter plane, though it was of little practical significance.

Following World War II, von Braun, along with 500 of his top scientists, surrendered to the Americans and established a new facility in Huntsville, Alabama, to build even more advanced rockets. Other German rocket scientists went to the Soviet Union — not all by choice.

Both in the United States and in the Soviet Union, the primary focus of rocketry continued to be military applications, particularly missiles capable of carrying nuclear warheads.

But the rocket designers themselves had other ambitions.

“Before This Decade Is Out”

On October 4, 1957, the Soviet Union launched Cпутник-1 (Sputnik 1), the first artificial satellite to orbit the Earth, and in the process initiated the Space Race between the Soviet Union and the United States. In the US, Sputnik was seen as a national humiliation. President Dwight D. Eisenhower ordered an acceleration of Project Vanguard, the US satellite launch program, but the first attempt ended in disaster when the rocket exploded on the launchpad on national television.

By the time the US managed to get a satellite in orbit, the Soviets already had two.

In 1961, the Soviets won another distinction when cosmonaut Ю́рий Гага́рин (Yuri Gagarin) became the first human in space. Three weeks later, American astronaut Alan Shepard completed a suborbital flight in the first Mercury mission.

In between Gagarin and Shepard, President John F. Kennedy asked his vice-president, Lyndon Johnson, to explore opportunities for the US to catch up in space, and Johnson recommended a piloted moon landing. Kennedy concurred, giving his blessing to the National Aeronautics and Space Administration’s (NASA) Apollo program and establishing its goal in a speech before a joint session of Congress: “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.”

Meanwhile, the Soviet Union continued to set records, including the first dual-piloted flight and the first woman (and first civilian) in space. At the time, the Soviet program was shrouded in secrecy, so much so that the name of the head of their space program was classified — a mysterious figure known only as the “Chief Designer.” His real name, Серге́й Королёв (Sergei Korolev), would only be revealed publicly well after his death. Photographs of the Soviet launch complex, Байқоңыр ғарыш айлағы (Baikonur Cosmodrome), now located in Kazakhstan, were highly classified, but no more. (Here's a picture.)

Baikonur Cosmodrome, Kazakhstan


The US Mercury program gave way to Gemini, a series of two-person missions. It was during Gemini that the US first crept ahead of the Soviet Union, setting records for length of flight, docking of spacecraft in orbit, and human extra-vehicular activity — better known as spacewalks.

Danger in Space!

By the middle of the 1960s, both nations were in a neck-and-neck race. The Soviet Union, under the leadership of the Chief Designer, planned a series of manned lunar flyby missions followed by a manned lunar landing planned for September 1968. In the United States, Gemini gave way to Apollo.

Both the Soviet and American programs experienced their share of disasters. In the Soviet Nedelin catastrophe, an exploding rocket at Baikonur Cosmodrome in Kazakhstan killed between 78 and 150 top Soviet personnel. Cosmonaut Валентин Бондаренко (Valentin Bondarenko) died in a training accident; the government erased his existence from their records to avoid embarrassment.

On the US side, almost everyone thinks that only three astronauts died in racing to the moon: Mercury and Gemini astronaut Virgil “Gus” Grissom, Gemini astronaut Edward White, and Roger Chaffee, who died in a cabin fire during a rehearsal of the launch sequence of Apollo 1. There were more: Theodore Freemann, Elliot See, Charles Bassett, and Clifton “C.C.” Williams all died in training accidents involving T-38 jet fighter trainers. Robert Lawrence, who would have been the first African-American astronaut, died in an F-104 Starfighter crash. Although their names were not erased from the history books, they have sadly been almost completely forgotten.

There were numerous near disasters. The Vostok 1 service module didn’t detach from the reentry module in time, sending the spacecraft into a spin. Grissom’s Mercury capsule hatch malfunctioned at splashdown, nearly drowning him. Voshkod 2, Gemini 8, Soyuz 5, and Apollo 12 all had failures or near disasters during their mission.

Even Apollo 11, in which US astronauts Neil Armstrong and Buzz Aldrin landed on the moon, had a failure of the navigation and guidance computer during the lunar descent. Armstrong landed the lunar module (LM) manually. Aldrin accidently broke the circuit breaker for the main liftoff engine, which might have stranded the astronauts on the lunar surface, but the astronauts were able to flip the switch using a felt-tip pen. On the return flight, the Guam tracking station failed, jeopardizing communication during the final stages of the return flight.

Thirteen

Although the United States officially “won” the space race with Apollo 11 on July 20, 1969, there would be five more missions to the Moon, during four of which astronauts walked on the lunar surface. The exception was Apollo 13, the seventh manned mission in the program.

About Apollo 13, more next week…

The CHAOS Report (Managing Impossible Projects, Part 3)





Photo: Baggage system, Denver International Airport


The following series is adapted from a keynote I delivered at the Washington, DC, chapter of the Project Management Institute back in August. Parts also come from my book Creative Project Management (with Ted Leemann), published by McGraw-Hill. 



The annual Standish Group’s CHAOS Report, which tracks software project performance reported these abysmal numbers for 2009:

  • 32% on time, on budget, to spec
  • 44% finished late, over budget, or partially completed
  • 24% failed, cancelled, or abandoned

Why do so many projects fail, either in part or in whole?

Certainly, there are badly managed projects — even some headed by PMPs. But it’s hard to blame a 68% defect rate on poor practitioners alone.

Sometimes the problem is the definition of success. By the logic of project management, the Leaning Tower of Pisa was an abysmal failure: late, over budget, and…well, aren’t buildings supposed to be straight? The Standish Group would clearly label the tower as a failed project, yet if the tower didn’t lean, who today would bother to visit?

The third reason, of course, is that the project was problematic to begin with — arguably or actually impossible. This can happen for a variety of reasons. In the case of Apollo 13, the constraints of time, resources, and performance were established by the situation, not by the will or desire of the project managers or owners. They were what they were — whether they were achievable was a separate issue.

In the Battle of the Bulge, the German Ardennes offensive had already begun. We would be able to get troops to the front to relieve the pressure on beleaguered First Army units, or we wouldn’t. Neither project managers nor project owners necessarily control the constraints that drive their projects.

Sometimes we’re just making a guess when we establish a project’s constraints. The original budget for Denver International Airport was $1.2 billion, and the original deadline was October 1993. The final price came in at $4.8 billion and the actual opening date was February 1995. (The infamous automated baggage system, budgeted at $186 million, wasn’t cancelled until 2005, by which time its construction costs were increasing at a staggering $1 million a day!)

Denver wasn’t an example of engineering or technical failure — no, not even the baggage system. The failure was driven by political considerations, including a nonstop war among several key stakeholders. When customer conflict generates mutually exclusive requirements, “impossible” becomes just another word for nothing left to lose.

In any event, we project managers are hired hands. Sometimes we may do double duty as customers or sponsors of our own projects, but when we put on our PMP hats, we’re here not to decide, but to execute. We are bound by the decisions and choices of others, and sometimes we start the project on the precipice of failure. After all, how many of you get to decide your own timelines, set your own budgets, and establish your own performance requirement?

I didn’t think so.

Still, you don’t want to be too quick to pull the trigger. Let’s imagine that you have a project and your experience tells you it can’t be done. Isn’t delaying the inevitable bad news just going to make the problem worse?

That depends on what you do in between receiving the assignment and giving the answer. Even if your project’s impossible, or at least compromised, there’s still a customer problem needing to be solved. Telling people what they can do and what they can have tends to get a better reception than telling people what they can’t do and what they can’t have.

That’s why the first step in managing a potentially impossible project is analysis. When you analyze an apparently impossible or potentially impossible project, you may learn different things.


  1. You confirm that the project is in fact impossible, and can provide evidence to the customer. You and the customer can begin to figure out what alternatives may exist or how to deal with the consequences of an unsuccessful project.
  2. You confirm that the project as originally proposed is in fact impossible, but are able to find potential changes that will make the project possible, which you can present to the customer.
  3. You confirm that the project as stated is in fact impossible, but are able to offer alternatives and compromises that might satisfy at least some of the customer’s requirements and needs, or close part of the gap.
  4. You can’t confirm that the project is in fact impossible, but you can identify at least some of the risks and challenges you face, which you and the customer can then assess.
  5. You find a creative way around the barrier that made the project impossible, and achieve the original goal.

Even if your analysis leads to the first outcome (it’s just flat impossible), however, your situation is still improved by your ability to give a thoughtful reply with supporting evidence, and your attitude in making a good-faith attempt to solve the problem.

Partial successes (outcomes two, three, and four) are a marked improvement. Even if the project is impossible — or highly risky — as stated, the customer may be able to get a significant portion of what he or she wants. Plus, it’s well known that the first approximation of available constraints may not be the final word. There may be more to draw on. And again, people tend to react better to hearing what they can have, and less well to hearing what they can’t have.

We renovated our house last summer, and the project was on time, exceeded our expectations — and cost about twice as much as we’d planned. We still call it a rousing success, because we never really expected to meet the budget anyway. It was a hope, not a realistic assessment. The Standish Group would call it a failure, but we don’t — and the customer is always right.

The fifth outcome (solve the problem with creativity) is ideal, but often challenging and not always successful.  The best direction to find the creative answer is, paradoxically, to focus on the barriers in the first place.

Potentially Impossible (Managing Impossible Projects, Part 2)

The following series is adapted from a keynote I delivered at the Washington, DC, chapter of the Project Management Institute back in August. Parts also come from my book Creative Project Management (with Ted Leemann), published by McGraw-Hill. 


The Most Dangerous Word

At the outset of the project, you may not always know whether the project is possible or not. That’s why the process of managing an impossible — or potentially impossible — project begins at the outset, during the very first stages of project initiation.

Here’s one of Dobson’s Laws of Project Management: The most dangerous word in project management is a premature “yes.”

Premature certainty, whether it’s positive or negative, can backfire. Saying “yes” before you really know what you’ve said “yes” to can result in a world of trouble.

You can also get in a world of trouble by being too quick to say “no.” Even if your experience and wisdom tell you the project’s impossible on the face of it, saying so too quickly will produce a negative reaction. And, frankly, sometimes “no” is just not going to be an acceptable answer.

When you say, “Sorry, that’s impossible,” they think, “You didn’t even try!”

Failure, Alas, Is an Option 


Let’s set the Way-Bac machine for April 14, 1970, just about 56 hours into the flight of Apollo 13. With the spacecraft about 200,000 miles away from Earth, Mission Control asked the crew to turn on the hydrogen and oxygen tank stirring fans. About 93 seconds later there was a loud “bang.” Oxygen tank #2 had exploded.


If American Movie Classics ever ran a series of “Great Project Management Movies,” surely Ron Howard’s Apollo 13 would be a natural candidate. Faced with a potentially disastrous accident, project teams overcome one potentially fatal barrier after another to bring the crew safely back to earth, guided by mission director Gene Kranz’s mantra, “Failure is not an option.”

But of course failure is an option, and in the case of the Apollo 13 mission, the odds were heavily stacked against a happy outcome— and everybody (including Gene Kranz) had to be well aware of that fact. Within the overall project “get the astronauts home safely,” there were numerous subprojects, including:

  • Develop a power-up sequence that draws fewer than 20 amps
  • Calculate a burn rate to get the reentry angle within tolerance using the sight of the Earth in the capsule window as the sole reference point
  • Design a way to fit the square command module carbon dioxide scrubber filter into the round Lunar Excursion Module (LEM) filter socket.

That last subproject was vital, because the LEM’s carbon dioxide scrubbers were designed to take care of he needs of two people for a day and a half, not three people for three days. And nobody ever imagined that the command module scrubbers would need to be used in the LEM, so they weren’t designed to be compatible. They’re square, and the necessary holes are round. Meanwhile, the carbon dioxide levels are already past 8, and at 15 things become dangerous, and eventually deadly. As the engineers gather in a conference room, boxes of miscellaneous junk — basically everything that’s loose on board the spacecraft — are being dumped on tables.

Managing a Crisis Project

Let’s look at the project management problem.

It’s easy to build a carbon dioxide filter on Earth; there’s a standard specification, a deadline measured in weeks, if not months, and all the resources you need are easy to acquire. In a crisis situation, such as existed aboard Apollo 13, the project looks a little different.

At the beginning of the project, the engineers involved could not know whether the project would turn out to be ultimately impossible. Impossibility could exist in any of the three fundamental constraints.

  • Does the time available to accomplish the project equal or exceed the time necessary? 

In developing a replacement for the Apollo 13 mission’s overloaded carbon dioxide filter, engineers were constrained by the amount of time until the astronauts became too impaired to build what they designed. If the deadline turns out to be too short, then the project is impossible.

  • Are the resources needed to accomplish the project less than or equal to the resources available? 

The project was constrained by what was actually available on the spacecraft. If their resources are short by even one critical component, no matter how small — a 20¢ screw — the project is impossible.

  • Are the performance criteria achievable within the outer boundaries of the other constraints? 

If the improvised filter can’t be made to work long enough for the astronauts to reach Earth orbit when they can return to the command module, then the project is impossible.

As we all know, the Apollo 13 engineers did come up with a workable solution, but that was hardly guaranteed. Had the constraints been slightly different — less time, fewer resources, more challenging performance standards — the outcome would likely have been failure.

But that doesn't mean you shouldn't try.

Failure *Is* An Option!

You probably won’t see the American Movie Classics channel run a festival of ‘‘Great Project Management Movies’’ any time soon, but if they did, Ron Howard’s motion picture Apollo 13, based on the real-life story, would be a natural candidate. Faced with a potentially disastrous accident, project teams overcome one potentially fatal barrier after another to bring the crew safely back to Earth, guided by mission director Gene Krantz’s mantra: ‘‘Failure is not an option.’’

But of course, failure is an option. Sometimes, it looks like the most likely option of all.

The odds in the actual Apollo 13 disaster were stacked against a happy outcome, and everyone—including Gene Krantz—had to be well aware of that fact. One of the key scenes in the movie involves a team of engineers trying to figure out how to rig a CO2 filter out of miscellaneous junk.


  • The time constraint: before the CO2 levels overwhelm the astronauts. 
  • The performance goal: to work well enough to let the astronauts breathe during the long trip home. 
  • The budget: the junk on the table. 


And no one knows whether it’s even possible.

How do you balance the value of realism against the value of optimism in solving problems?

One way is to reject the false dilemma the question poses. Failure is not only an option, it’s a gateway to success ... if you fail in the right dimension.

If there is a trade-off to be made between the time constraint and the performance criteria, we know that ultimate failure—the death of the Apollo 13 astronauts—comes most rapidly from failure to meet the time constraint. That is, if we build a perfect CO2 filter, but we finish it too late, we’ve still failed. Perfect performance does not compensate for a failed deadline.

But wait! Why isn’t the reverse equally true? If you fail to meet the performance criteria, isn’t it irrelevant how quickly you fail to do so? Actually, it depends on the extent of the failure.

To illustrate, let’s look at this scenario: You’ve managed to come up with an inefficient partial solution that will last only half as long as it’s going to take to get the astronauts back home, but you’ve done so within the original time constraint. Do you take this solution? Absolutely!

Although you have failed to make the performance goal for the project within the original time constraint, you’ve reset the game clock. With a day or more to work instead of mere hours, your chance of finding a solution that solves the remainder of the problem has become that much more possible.

The right kind of failure is not only an option, but sometimes a desirable one. In this project, we can’t accept a failure to meet the time constraint, but we can live with a partial performance failure and stay in this game.
