Solving the Bird Strike Problem
Public awareness of the danger of bird strikes to aircraft has greatly increased since the January 15 incident in which Chesley “Sully” Sullenberger expertly guided the crippled US Airways Airbus to safety in the Hudson River. On Friday, April 3rd, USA Today published a debate on airline passenger safety due to bird strikes. The newspaper presented the case that even though large bird populations are rising, and thus the risk of catastrophic collisions is also increasing, the federal government is responding by trying to hide the data. In late March, the FAA proposed blocking access to its bird strike database managed by Embry-Riddle Aeronautical University on the basis that public access to the terribly complex records would “stifle reporting”. The opposing view, published by USA Today as excerpts from the FAA’s proposed rules, basically established the position that “voluntary reporting is good enough”.
But according to the National Transportation Safety Board (NTSB, 1999), less than 20% of bird strikes are reported annually. How do we raise the profile of reporting, and encourage pilots and aviation workers to comply?
This question was answered by Dekker & Buurma (2005) in a paper to the International Bird Strike Committee in Athens. After all, the catastrophic failure of aircraft due to bird strikes is an international problem that readily crosses international boundaries and cultures, so it should not be a surprise that this issue has been taken up by aviation analysts worldwide. They recommend that we need to do the following to reduce the risks to human populations from bird strikes to aircraft:
- We need to establish effective standards for defining what a bird strike is,
- We need to decouple the reporting procedure from the international governance structures (FAA-like agencies as well as insurance providers), so that pilots and airline employees do not have to fear recrimination for their reports, and
- We need to promote behaviors that encourage awareness and reporting, such as targeted inspections, clear guidelines, ensuring that the reports actually reach the databases, acceptance of the paperwork required by reporting, relieving time pressure so that there is available opportunity for reporting, and remove the reasons why people are fearful to report.
More details are provided in Dekker & Buurma’s paper at http://www.int-birdstrike.org/Athens_Papers/IBSC27%20WPII-1.pdf:
Quality assurance. Ultimately, bird strikes are the currency with which the effectiveness of preventive measures is settled. This applies to all aspects of the bird strike problem: improved impact resistance of aircraft, wildlife policy of airfields (and their surrounding) and operational procedures of airliners…
For the simple reason that the civil aviation authorities do play a double role (condensation point for information and authority that supervises all other parties) the relations are contaminated and dominated by juridical arguments. This means that there is a tendency for national databases to be biased in such a way that liability is excluded. This in turn means that the existing databases do contribute only in a limited way to the scientific, educational and quality assurance goals. If mandatory reporting is to be successful it has to be organised in a different, non punitive way.
Enhanced reporting “could be realised by unlinking the national bird strike databases from the supervising authority… [and then] the emphasis will change from juridical to scientific and educational.
The solution seems simple – remove the punitive penalties for reporting, and possibly institute incentives for accurate reporting. This could create jobs and open opportunities for researchers to investigate the problems more openly. What do we have to lose?

Sociotechnology, Public Policy and the Global Economic Crisis
Today’s Washington Post includes an article on “How We Can Restore Confidence” in our economy. Confidence, after all, is one of the energetic drivers of the economy – without it, spending grinds to a halt, and the delicate equilibrium of economic flow is jeopardized. The author, Charles T. Munger, reflects on the reasons for the meltdown:
Many contributors to our over-the-top boom, which led to the gross bust, are known. They include insufficient controls over morality and prudence in banks and investment banks; undesirable conduct among investment banks; greatly expanded financial leverage, aided by direct or implied use of government credit; and extreme excess, sometimes amounting to fraud, in the promotion of consumer credit. Unsound accounting was widespread.
How did we, as a society, collectively allow these things to happen? Because many people were motivated by the huge profit potentials associated with real estate speculation, new financial instruments, and expanded financial leverage. This motivation towards self-interest, according to sociotechnical researcher Brian Whitworth of Massey University in New Zealand, tends to destabilize society by breaking down institutions and other systems intended to promote social order.In “A Social Environment Model of Socio-Technical Performance” he explains why [with my annotations in brackets]:
“While traditional technology like word processing supports individual competence, socio-technical systems support some sort of community synergy and have defenses against anti-social defection” [that is, acting against the interests of the group in a detrimental way (e.g. violation of human dignity, theft, cheating)]. “The social environment model suggests that people in society recognize both [social good and self-interest], and [tend to]combine them by anchoring one and applying the other. Anchoring social good then applying self-interest explains the highly profitable market trade systems of the last century, where individuals seek profit under social good laws. However contented individuals could anchor individual good, and then seek community benefit [through their positive, pro-social, individual contributions; Whitworth suggests that systems like online troubleshooting boards exemplify this approach because individuals have no incentive other than "good citizenship" to help others]. The latter is proposed to underlie the surprising successes of socio-technical systems.“
“Anchoring social good” is an intended outcome of public policy, which seeks to curb acts against society by instituting punishments. “Anchoring individual good” and seeking to apply one’s personal motivations for the greater good is a defining characteristic of successful socio-technical systems (like Amazon and eBay). The latter is aided by effective community policing where people take it upon themselves to enforce the rules of “good citizenship”.
This leads me to ask: what’s the socio-technically inspired public policy equivalent that might help us rectify the global financial crisis? I don’t have any good answers, but I think this research provides an interesting backdrop to analyze the situation against.
Continuous Improvement Begins With Standards
Software is the executable representation of knowledge. [1] As a result, I find that software development provides a fruitful basis for exploring how problem solving is done by diverse team members in a cooperative (or even combative!) context.
Here is one example. In June 1997, Tom Gilb wrote an article for Crosstalk on “Requirements-Driven Management”. He noted that his purpose was intended to discuss, among other things, “some of the current major problems in systems engineering.” I stumbled upon this article again over the weekend, and it’s still as relevant now as it was a decade ago.
Standards are a prerequisite for systematic continuous improvement; the means to achieve an improvement process, not the ends, according to Glib. Furthermore, he remarks that Deming’s perspective on continuous improvement establishes, in part, that the reason we should adopt standards is to normalize our project to other projects . Once we do that, we’ve opened the doors to be able to use industry best practices, derived from other projects who also applied the standards – so that we can “clearly see the effect of any changes experimentally introduced into a process and not have to worry too much about other potential factors that impact the results.”
Learning, learning, learning. It’s all about continuous improvement through continuous learning, and in presenting this, Gilb is essentially promoting the same philosophy as Alistair Cockburn’s Cooperative Game Manifesto for Software Development. Both see the learning process as the key to successful software development. (So why do we not focus on this aspect of development more?) Glib addresses the issue of learning directly:
“The time has come to recognize that projects are so large, so complex, so unpredictable, and so state-of-the-art new that we have no practical alternative except to maximize our learning process during the project and as early as possible in the project life. “
In this article, Gilb also presents “Evo” – short for “Evolutionary Project Management” – which has been used at IBM since 1970. It’s an implementation of Deming’s PDCA (Plan-Do-Check-Act) approach, and the author likens it to Humphrey’s Personal Software Process (PSP).
[1] This definition is credited to Eric Sessoms, who I consider a true artisan of software development. See some of his work at libraryh3lp.com. He likes the elegance of simplicity in his software.
What are Standards?
Standards represent “accepted ways of doing things” and can be defined as sets or features of characteristics that describe products, processes, services or concepts. (National Research Council, 2005) Alternatively, standards can be described as “rules, regulations, and frameworks intended to enable individuals, groups, organizations, countries and nations to achieve goals.” (Spivak & Brenner, 2001) According to these authors, there are five types of standards: 1) physical or measurement standards; 2) standards for symbols, meanings and language; 3) standards for products and processes, including test validation, quality assurance, and operating procedures; 4) standards for systems (including management systems and regulatory systems); and 5) standards for health, safety, the environment and for ensuring other consumer interests. Standards may be compulsory (as in the case of legal and regulatory standards, such as the Sarbanes-Oxley requirements for financial reporting) or voluntarily adopted (as in the case of product interface standards such as USB for computer peripherals).
Because standards are a mechanism used by social groups to promote norms, and to facilitate the creation of artifacts that advance human capabilities, standards are technologies. (Recall that Random House defines technology as “The sum of the ways in which social groups provide themselves with the material objects of their civilizations.”)
What can standards do for you and your projects? The importance of standards can be explained in terms of the eight goals that standards can be used to achieve (Blind, 2004):
- Compatibility – facilitating cooperation between people, processes, systems, or technologies
- Communication – facilitates information flow between people, processes, systems or technologies
- Conformance – provides a common basis to establish competency or define excellence
- Continuous Improvement – helps organizations leverage the “lessons learned” that are imbued within the standards
- Establish Order – promotes consistency, reliability and effective communications
- Prescribe Behavior – enables organizations to reduce variability between people and systems
- Promote Social Order – establishes a basis for legal and ethical behavior
- Establish Shared Meaning – provides a context for communication, compatibility and conformance
A standard is “working” if it accomplishes one or more of these goals (depending, of course, on how relevant and pertinent the goals are to the project that is being pursued). For example, it’s probably not very important for two computer devices to “promote social order” if they need to communicate. But it’s definitely important for people.
