Pulling Off the Impossible Under Immense Pressure: Leadership Lessons from Captain Sully

May 25, 2020 By Nagesh Belludi Leave a Comment

I recently watched Sully (2016,) the overrated Clint Eastwood-directed drama about the US Airways Flight 1549 incident, aka the “Miracle on the Hudson.”

Sully Movie (2016) with Tom Hanks, Clint Eastwood In summary, on 15-Jan-2009, Captain Chesley “Sully” Sullenberger (played by Tom Hanks) heroically dead-sticked his Airbus A320 aircraft in New York City’s Hudson River after both the aircraft’s engines failed from a bird strike. He then helped get passengers and crew off uninjured.

Sully centers on Sullenberger’s post-decision dissonance. To spin the real-life six-minute flight and the 24-minute swift rescue into a 96-minute Holyrood extravaganza, the filmmakers devised an antagonist in the form of National Transportation Safety Board (NTSB) investigators who try hard to blame Sullenberger for the mishap.

Overdramatized Portrayal of the NTSB Investigators

On the screen, the smirking NTSB investigators use flight simulators and computer analysis to second-guess Sullenberger’s lightning-quick decisions. They would have rather he made it to an airport nearby—a possibility that he had instantly judged was not viable given his 40 years of flying experience.

Contrary to Sully‘s portrayal, the NTSB was unequivocal that landing the aircraft on the Hudson was the right call. In his memoir, Highest Duty: My Search for What Really Matters (2009,) Sullenberger mentions that he was “buoyed by the fact that investigators determined that [first officer] Jeff and I made appropriate choices at every step.”

In the course of the real-life 18-month investigation of Flight 1549, the NTSB did investigate the odds of landing the aircraft in a nearby airport. Exploring all possible flaws that contribute to a crash is part of the NTSB’s charter. The NTSB, like other accident-investigation agencies, concerns itself principally with preventing future accidents. It rarely seeks to assign blame, nor does it make the pilots justify their actions.

The Complex Leadership Requirements of Flying

Apart from the sensationalized portrayal of the NTSB investigators, Sully misses the opportunity to call attention to the complex leadership requirements of aviation. Flying a civil aircraft is characterized by a high level of standardization and automation, while still placing a strong emphasis on formal qualification and experience.

Today, highly trained pilots have to work with ever more complicated and autonomous technology. The routinization must be weighed up against deliberate action. On Flight 1549, the A320’s much-studied fly-by-wire system allowed the pilots to concentrate on trying to resurrect the engines, starting the auxiliary power unit (APU,) and deciding the flight path in the direction of the Hudson. Airbus’s legendary computer controls will not allow the pilots to override the computer-imposed limits even in an urgent situation. Sullenberger and others have commented that lesser human-machine interaction may perhaps have allowed him a more favorable landing flare and helped him temper the aircraft’s impact with the water.

Aircrews now consist of ad hoc teams working together typically only for a few flights. They build their team quickly and rely on the crew’s collective knowledge and experience to round out the high levels of standardization.

Due to the complex demands for leadership in aircrews, specialized training programs such as Crew Resource Management (CRM) are in place to improve crew communication, situational awareness, and impromptu decision-making. These systems were established to help crews when technical failures and unexpected events disrupt highly procedualized normal operations.

Furthermore, individual and organizational learning from accidents was institutionalized through mandatory reporting of incidents—not only within the airline involved but also across the aviation community.

Leadership Lessons on Acting Under Immense Pressure: The Context of Success

Owing to intuition, experience, and quick coordination, Sullenberger was able to “land” the aircraft on the Hudson within four minutes following the bird strike and have his passengers and crew quickly evacuated onto the aircraft’s wings and onto rafts.

The rapid and highly complex coordination required for this extraordinary achievement was only achievable because of exceptional leadership, exemplary decision-making under stress, and the technical skills of both the cockpit- and cabin-crew.

The pilots were highly experienced—Sullenberger even had experience as a glider pilot. Further contextual factors—the calm weather on that afternoon and the proximity of NY Waterway ferries—helped bring this accident to a good end. All this facilitated the almost immediate rescue of passengers and crew from the rapidly sinking aircraft and the frigid water.

'Highest Duty What Really Matters' by Chesley Sullenberger (ISBN 0061924695) On Another Note, Sullenberger’s memoir, Highest Duty (2009,) is passable. The most interesting part of the book is the last fourth, where he discusses Flight 1549 and what went through his mind. Interestingly, Sullenberger writes that even after he realized that the plane was in one piece after hitting the water, he worried about the difficulties that still lay ahead. The aircraft was sinking: everyone had to be evacuated quickly. The passengers could survive only for a few minutes in the frigid waters of the Hudson.

The Power of Negative Thinking

May 21, 2020 By Nagesh Belludi Leave a Comment

Stoic philosophy recommends a practice called premeditatio malorum (“the premeditation of evils,”) i.e. intentionally visualizing the worst-case scenario in your mind’s eye.

The first point is to acknowledge that misfortunes and difficulties could, rather than certainly will, come about. The second is to envisage your most constructive response should the worst-case scenario transpire. For instance, if you’d lose your job due to coronavirus, what resources could you rely on, and how could you handle the consequences?

The direct benefit of premeditatio malorum is in taming your anxiety: when you soberly conjure up how bad things could go, you typically reckon that you could indeed cope. You’ll not dwell in the negative thoughts. Even the worst possible scenario couldn’t be so terrible after all.

Another surprising benefit of negative visualization is in raising your awareness that you could lose your relationships, possessions, routines, blessings, and everything else that you currently enjoy—but perhaps take for granted. This increases your gratitude for having them now.

This Stoic exercise has an equivalent in Buddhist meditation-based mindfulness practices that encourage nonjudgmental awareness of unpleasant sensations (the vedanā.)

Your emotions, sensations, and events are in flux. They arise and pass. You’re merely to regard yourself as the observer of these thoughts and feelings, but you’re not to identify with them. You are not your thoughts … you are not your feelings. The Buddhist teacher Jack Kornfield writes in The Wise Heart: A Guide to the Universal Teachings of Buddhist Psychology (2015,)

Thoughts and opinions arise but they think themselves and disappear, “like bubbles on the Ganges,” says the Buddha. When we do not cling to them, they lose their hold on us. In the light of awareness, the constructed self of our identification relaxes. And what is seen is just the process of life, not self nor other, but life unfolding as part of the whole.

Idea for Impact: Could you benefit from reflecting on how you think of potential negative events?

An awareness of the possible—and the self-determining attitude—can be quite liberating. Premeditatio malorum is a surprisingly useful technique, if only with a scary name.

“What then should each of us say as each hardship befalls us? It was for this that I was exercising, It was for this that I was training,” as Epictetus philosophized in Discourses (3.10.7–8.)

Everything in Life is Perception

May 18, 2020 By Nagesh Belludi Leave a Comment

When J. K. Rowling wrote the novel The Cuckoo’s Calling (2013) and published iu under the pseudonym Robert Galbraith, she sold less than 1,500 copies in print in three months. When word got out that J. K. Rowling had written the book, The Cuckoo’s Calling immediately jumped to the top of the best-seller lists. In just a few months, the book had sold 1.1 million copies.

When the internationally-acclaimed violinist Joshua Bell played his famous 300-year-old, $3.5 million Stradivarius violin at a Washington, D.C. metro station in 2007, only seven out of the 1,097 people who walked past him during his 45-minute performance stopped to listen. Dressed in street clothes, Bell made just $32.17 in tips tossed into the open violin case at his feet—plus $20 from one person who actually recognized him. People otherwise pay hundreds of dollars to hear him perform at fancy concert halls around the world.

The Yale psychologist Paul Bloom, author of How Pleasure Works (2010,) has described,

When we get pleasure from something, it’s not merely based on what we see or what we hear or what we feel. Rather, it’s based on what we believe that thing to be.

And so, someone listening to the music of Joshua Bell is going to hear it differently and like it more if they believe it’s from Joshua Bell. If you hear the same music and think it’s from some scruffy, anonymous street performer, it doesn’t sound so good.

And I think that’s a more general fact about pleasure. I think wine doesn’t taste as good if you don’t know it’s expensive or special wine. A painting is going to look different to you, and you’re going to value it differently, depending on who you think created it.

Bloom has explained how our minds shape the way a thing will be—because we behave in proportion to our expectations:

We don’t just respond to things as we see, feel, or hear them. Rather, our response is conditioned by our beliefs of where things come from, what they’re made of, or what their hidden nature is. This is true, not just for how we think about things, but how we react to things.

Idea for Impact: Perception is Reality

Expectations color people’s perceptions, and satisfaction with any experience depends on their perceptions going into it.

What you make others think you’re offering them—your skills, your services, your products—profoundly affects their experience. The right expectations can alter anything from valueless to priceless.

However, as Dr. Johnson has warned, “we ought not to raise expectations which it is not in our power to satisfy.—It is more pleasing to see smoke brightening into flame, than flame sinking into smoke.”

Howard Gardner’s Five Minds for the Future // Books in Brief

May 8, 2020 By Nagesh Belludi Leave a Comment

In Five Minds for the Future (2006,) developmental psychologist Howard Gardner argues that succeeding in a rapidly evolving world requires five proficiencies:

  • The Disciplinary Mind: “Individuals without one or more disciplines will not be able to succeed at any demanding workplace and will be restricted to menial tasks.”
  • The Synthesizing Mind: “Individuals without synthesizing capabilities will be overwhelmed by information and unable to make judicious decisions about personal or professional matters.”
  • The Creating Mind: “Individuals without creating capacities will be replaced by computers and will drive away those who have the creative spark.”
  • The Respectful Mind: “Individuals without respect will not be worthy of respect by others and will poison the workplace and the commons.”
  • The Ethical Mind: “Individuals without ethics will yield a world devoid of decent workers and responsible citizens: none of us will want to live on that desolate planet.”

Gardner is best known for his work on multiple intelligences—the theory that cast serious doubts about the simplistic concept of a “single” intelligence, measurable by something like IQ. Gardner’s notion that “there is more than one way to learn” has transformed education in the U.S. and around the world.

Recommendation: Speed-read Five Minds for the Future. Written through the lens of a skills-development policymaker, Gardner’s theses and prescriptions aren’t ground-breaking but make for thoughtful reflection. Complement with Gardner’s The Unschooled Mind (1991; summary.)

How to Improve Your Career Prospects During the COVID-19 Crisis

May 7, 2020 By Nagesh Belludi Leave a Comment

Now that the COVID-19 pandemic has plunged the world into despondency and uncertainty, it’s easy to worry about your career prospects, feel risk-averse, and become inert.

However, if you could look beyond the short-term challenges, now’s a good time to take on new skills, tend to your network, and accelerate your long-term career prospects.

Here’s how to take a bit of initiative and think creatively about your career during the current lockdown.

  1. Reflect upon your goals for your life and career. Think clearly through the steps you must take to realize your aspirations.
  2. State clearly your aims. If you want to earn more or get a better responsibility, speak to your boss about what it’ll take to secure a promotion.
  3. Seek specific feedback, but don’t just reflect on the past. Asking for feedback puts you—not your boss—in the driver’s seat. Ask lots of questions and decide what you could do to make a positive change.
  4. Redefine your goals at work. Identify worthwhile measures of success. Agree on targets that stretch but don’t strain.
  5. Work with your boss to find gaps in your experience. Find projects where you could develop and use those skills.
  6. Don’t try to do everything. Prioritize. Ask yourself, “Where do my strengths lie?” Focusing on one or two areas could help you isolate and sharpen the necessary skills to move up.
  7. Seek out new opportunities. Be alert to points of diminishing returns on learning new skills.
  8. Take the lead on a project that others don’t find particularly interesting (see Theo Epstein’s 20 Percent Rule.) You could not only learn by way of broader experiences and gain confidence but also become more visible to management and situate yourself for a promotion.
  9. Offer to share responsibility. Take an interest in your colleagues’ work. You could win over grateful allies and open up new opportunities within your company.
  10. Reevaluate what’s essential. To the extent possible, divest yourself of the boring, time-wasting, frivolous, and worthless—anything that doesn’t “move the ball down the field.”
  11. Pursue side projects. Cultivating knowledge and trying out new skills during your free time is a definite path to career reinvention.
  12. Seek out mentors. Make the right contacts. Bear in mind, those who influence decisions may not necessarily be the ones at the top.
  13. Begin actively networking. It’s never late to put together a range of experts whose knowledge and experience you could tap into.

Idea for Impact: Mulling over how to improve yourself and enhance your career is a great shelter-in-place project. As President Dwight D. Eisenhower once declared, “Plans are useless but planning is indispensable.”

Make ‘Em Thirsty

May 6, 2020 By Nagesh Belludi Leave a Comment

Sony’s Akio Morita, like Apple’s Steve Jobs, was a marketing genius. Morita’s hit parade included such iconic products as the first hand-held transistor radio and the Walkman portable audio cassette player.

Key to Morita’s success was his mastery of the art of the pitch. Morita pushed Sony to create consumer electronics for which no obvious need existed and then generated demand for them.

The best marketing minds know how to create a customer—previously unaware of a problem or an opportunity, she becomes interested in considering the opportunity, and finally acts upon it.

Coca-Cola marketers are but creating a thirst by showing the fizzle a freshly poured glass in Coke ads. “Thirst asks nothing more,” indeed.

The marketing guru Seth Godin has said, “So many people are unhappy … what they have doesn’t make them unhappy. What they want does. And want is created by the marketers.” Recall the old parable,

A sales trainee was trying to explain his failure to close a single deal in his first week. “You know,” he said to his manager, “you can lead a horse to water, but you can’t make him drink.”

“Make him drink?” The manager sputtered. “Your job is to make him thirsty.”

Idea for Impact: Whether you realize this or not, you’re in marketing, as is everybody else. You’re constantly pitching your ideas, skills, time, appeal, charm, and so forth. Study the art of the pitch. Master the art of generating demand for whatever it is you have to offer. Learn to “make ’em thirsty.” Marketing is everything.

It’s Probably Not as Bad as You Think

May 5, 2020 By Nagesh Belludi 1 Comment

The 20-40-60 Rule, believed to be written by humorist Will Rogers for his movie Life Begins at 40 (1935,) states,

When you are 20, you care about what everybody thinks of you.
When you are 40, you don’t care about what people think of you,
and when you are 60, you actually understand that people were too busy thinking about themselves.

In essence, don’t agonize about what other people are thinking about you. They’re perhaps busy worrying over what you’re thinking about them.

The 20-40-60 Rule became popular when venture capitalist Heidi Roizen cited it (incorrectly attributing it to the actress Shirley MacLaine) at a 2014 lecture at Stanford. First Round Capital’s Review has noted,

People have enormous capacity to beat themselves up over the smallest foibles—saying the wrong thing in a meeting, introducing someone using the wrong name. Weeks can be lost, important relationships avoided, productivity wasted, all because we’re afraid others are judging us. “If you find this happening to you, remember, no one is thinking about you as hard as you are thinking about yourself. So don’t let it all worry you so much.”

Idea for Impact: Don’t Beat Yourself Up Over Your Mistakes

Chances are, people around you aren’t nearly as critical of you as you are of yourself. No one’s going to remember or care about your mistakes, and neither should you.

Why You’ll Work Better with Plenty of Breaks during This COVID-19 Lockdown

April 27, 2020 By Nagesh Belludi Leave a Comment


Mix it Up; or, How to Beat Vigilance Decrement

In the mid-1940s, the British psychologist Norman Mackworth set about to investigate why, during World War II, the Royal Air Force’s radar and sonar operators would miss weak signals that could suggest submerged enemy vessels.

Mackworth was particularly interested in why this observed phenomenon was likely to happen more towards the end of the operators’ shifts.

The “Mackworth Clock” study established that after 30 minutes in an intense task, there was a deterioration of 10–15% in the accuracy of signal detection. Fatigue ensued, and blood flow to the brain decreased. This deterioration continued as the time on task increased. Mackworth also found that short breaks restored performance.

The Way Attention Works

Research on “vigilance” (that’s psychology-speak for attention) has demonstrated that attention is a limited resource. Most of us find it challenging to sustain constant attention to a single task for long periods, especially if the task were demanding, tedious, and boring. Students, for example, can’t concentrate and follow lectures for more a few minutes at a time. This notion of limited and waning attention is called “vigilance decrement.”

Sustained Vigilance Requires Hard Mental Work

Vigilance decrement also increases error rates and slows down reaction times, especially in tasks that need sustained attention—security personnel, surveillance-camera monitors, pilots and vehicle drivers, medical diagnostic screeners, students, and so on—even engineers who train self-driving cars.

As with Mackworth’s study, vigilance decrement is most pronounced when monitoring screens and displays, often over periods as short as 10 or 15 minutes.

TSA screeners in America, for instance, continually rotate positions throughout their shift to avoid making mistakes and missing details—especially small but important details. They even rotate among different stations. Every TSA officer is trained in all the tasks on the floor, including x-ray screening, searching bags, validating tickets and passports, and conducting pat-down searches. TSA agents take frequent breaks, sometimes resting for 30 minutes every two or three hours.

Idea for Impact: To Beat Vigilance Decrement, Take Truly Restful Breaks

  • Rest well before undertaking a task that requires sustained attention. The airline industry has specific guidelines for duty, rest, and sleep requirements to combat the risks of fatigue in aircrews.
  • Hand over surveillance tasks as frequently as possible.
  • Mix ’em up. Try interleaving—instead of focusing on a single task, frequently switch between different ones.

During the current COVID-19 lockdown, you’ll work better with breaks. Mix up how you sequence your work. Avoid doing the same tasks in the same order each day.

How to Have a Eureka Moment during the Coronavirus Lockdown

April 23, 2020 By Nagesh Belludi Leave a Comment

The best solutions to problems sometimes come about suddenly and unexpectedly when people aren’t actively working on their issues.

Psychologists call this phenomenon “incubation”—a brief shift away from a problem that could trigger a flash of insight as if from no additional effort. [Incidentally, “incubation” is very much a term in vogue during the current epidemic.]

Abundant anecdotes evoke creative breakthroughs made when inventors took breaks from working on their problems after many failed attempts to solve them.

‘Eureka Moments’ happen all the time

Perhaps the best-known case in point of incubation is that of the ancient Greek polymath Archimedes.

It’s plausible that Archimedes realized that he could investigate the suspected adulteration of Hieron II’s votive crown (“corona” in Italian/Latin, incidentally) by weighing it in water. The legend doesn’t appear in any of Archimedes’s known works.

That Archimedes leaped out from the bath in which he purportedly got the idea and ran home unclothed is likely a popular embellishment. The Roman architect Vitruvius first mentioned this spin to the story some 200 years after the supposed event:

[Archimedes] happened to go to the bath, and on getting into a tub observed that the more his body sank into it, the more water ran out over the tub. As this pointed out the way to explain the case in question, he jumped out of the tub and rushed home naked, crying with a loud voice that he had found what he was seeking; for he as he ran he shouted repeatedly in Greek, “Heúrēka, heúrēka.” meaning “I have found (it,) I have found (it.)

Millennia later, the scientific world is replete with the exclamation. In fact, the prospectors of California’s gold rush were so keen on the expression that it has appeared on the state seal since 1849, becoming the state’s motto in 1963.

Idea for Impact: To overcome a mental block, take your mind off the problem

After a period of conscious work, if you’ve reached an impasse that is blocking (“fixation”) your awareness of the solution to a problem, set it aside.

Remove yourself from the task. Take your mind off the problem. Go for a run, play with your dog, play an instrument, indulge in your favorite video game, take a shower, or embark on some optimally distracting hobby.

Creativity involves putting old ideas together in new ways. Your mind may be shuffling information at all times, even when you’re not conscious of it. You may just hit upon a solution during either your time away or when you return to the problem after the incubation period.

Five Where Only One is Needed: How Airbus Avoids Single Points of Failure

April 6, 2020 By Nagesh Belludi Leave a Comment

In my case study of the Boeing 737 MAX aircraft’s anti-stall mechanism, I examined how relying on data from only one Angle-of-Attack (AoA) sensor caused two accidents and the aircraft’s consequent grounding.

A single point of failure is a system component, which, upon failure, renders the entire system unavailable, dysfunctional, or unreliable. In other words, if a bunch of things relies on one component within your system, and that component breaks, you are counting the time to a catastrophe.

Case Study: How Airbus Builds Multiple Redundancies to Minimize Single Points of Failure

As the Boeing 737 MAX disaster has emphasized, single points of failure in products, services, and processes may spell disaster for organizations that have not adequately identified and mitigated these critical risks. Reducing single points of failure requires a thorough knowledge of the vital systems and processes that an organization relies on to be successful.

Since the dawn of flying, reliance on one sensor has been anathema.

The Airbus A380 aircraft, for example, features 100,000 different wires—that’s 470 km of cables weighing some 5700 kg. Airbus’s wiring includes double or triple redundancy to mitigate the risk of single points of failure caused by defect wiring (e.g., corrosion, chafing of isolation or loose contact) or cut wires (e.g., through particles intruding aircraft structure as in case of an engine burst.)

The Airbus fly-by-wire flight control system has quadruplex redundancy i.e., it has five flight control computers where only one computer is needed to fly the aircraft. Consequently, an Airbus aircraft can afford to lose four of these computers and still be flyable. Of the five flight control computers, three are primary computers and two are secondary (backup) computers. The primary and the secondary flight control computers use different processors, are designed and supplied by different vendors, feature different chips from different manufacturers, and have different software systems developed by different teams using different programming languages. All this redundancy reduces the probability of common hardware- and software-errors that could lead to system failure.

Redundancy is Expensive but Indispensable

The multiple redundant flight control computers continuously keep track of each other’s output. If one computer produces deviant results for some reason, the flight control system as a whole excludes the results from that aberrant computer in determining the appropriate actions for the flight controls.

By replicating critical sensors, computers, and actuators, Airbus provides for a “graceful degradation” state, where essential facilities remain available, allowing the pilot to fly and land the plane. If an Airbus loses all engine power, a ram air turbine can power the aircraft’s most critical systems, allowing the pilot to glide and land the plane (as happened with Air Transat Flight 236.)

Idea for Impact: Build redundancy to prevent system failure from the breakdown of a single component

When you devise a highly reliable system, identify potential single points of failure, and investigate how these risks and failure modes can be mitigated.

For every component of a product or a service you work on, identify single points of failure by asking, “If this component fails, does the rest of the system still work, and, more importantly, does it still do the function it is supposed to do?”

Add redundancy to the system so that failure of any component does not mean failure of the entire system.

If you can’t build redundancy into a system due to some physical or operational complexity, establish frequent inspections and maintenance to keep the system reliable.

Postscript: In people-management, make sure that no one person has sole custody of some critical institutional knowledge, creativity, reputation, or experience that makes him indispensable to the organization’s business continuity and its future performance. If he/she should leave, the organization suffers the loss of that valued standing and expertise. See my article about this notion of key-person dependency risk, the threat posed by an organization, or a team’s over-reliance on one or a few individuals.
