In this episode of the Data Show, I speak with Cassie Kozyrkov, technical director and chief decision scientist at Google Cloud. She describes “decision intelligence” as an interdisciplinary field concerned with all aspects of decision-making, and which combines data science with the behavioral sciences. Most recently she has been focused on developing best practices that can help practitioners make safe, effective use of AI and data. Kozyrkov uses her platform to help data scientists develop skills that will enable them to connect data and AI with their organizations’ core businesses.
We had a great conversation spanning many topics, including:
How data science can be more useful
The importance of the human side of data
The leadership talent shortage in data science
Is data science a bubble?

Incident response is like security: when you do it well, no one notices because everything just works the way it should. With both incident response and security, the costs are obvious to the organization while the benefits remain amorphous. And as with security, a lack of attention to incident response could be regretted—you can lose a good deal of money while your systems are non-functional. Even worse, your clients and customers might lose confidence in your product or organization, potentially costing you the entire business.
In this interview, Tim Craig and fellow Googler Gustavo Franco, a site reliability engineer (SRE), discuss the wide range of events that qualify as “incidents;” the need for a conscious, robust, and well-defined process for understanding them; the role of training; and how to get buy-in from management so you can spread incident response training throughout an organization.
The concept of incident response is very broad, according to Craig. It goes far beyond the people usually considered, such as SREs and network administrators. Imagine a major incident requires a statement from an executive who happens to be eight time zones away or on an airplane. Can you reach them quickly? Are your legal and PR teams ready? Thus, incident response can cross many teams and involve an entire organization.
Craig may also surprise you by elevating processes above tools. But this is natural because incident response is an organizational issue, not just a technical one. Tools are important, of course—more on that in a moment—but people are even more important. When you choose the types of incidents for which you need to train and prepare, consider not just what’s most important to the business, but also what can best teach your staff.
Ideally, when a disaster happens, everybody who can help will immediately take their places and perform a useful role, like the crew of an airplane or ship. This requires regular training, just as people who earn first aid and CPR badges must complete ongoing follow-up training.
Tools enter the picture in order to automate disaster recovery testing. Teams create software to aid as much as possible in the design, scheduling, and evaluation of side effects from tests. Incident response is often practiced and measured during these tests as well. Automation is important for several reasons:
- To scale up and protect as many aspects of your systems as possible, you need to shorten the amount of time a responder requires to create and run tests.
- To persuade busy coworkers to adopt incident response, you need to make it easy for them.
- To get approval for the incident response program from managers, you need to minimize costs, an aspect with which automation can help.
Many organizations can start small incident response initiatives without approval from higher management. But to move beyond isolated teams and to try out incident response where it really matters—on the production systems facing your clients—you’ll need buy-in from high up in an organization.
Craig endorses starting small and simple. He reminds the audience that Google has been practicing its current incident response program for 15 years. Don’t try to attain Google’s level of organization and automation from the start. It can be useful just to sit with the people responsible for handling incidents and talking through what they do, while making notes on paper. The chapter on incident response in The Site Reliability Workbook offers additional detail.
Craig and Franco use a couple abbreviations that I’ll define here:
- MTTM: Median time to mitigate, one of several terms designating how long you can take to recover from an incident.
- SLO: Service-level objective, part of a service-level agreement (SLA).
The term chaos engineering comes up during the interview, but Craig points out that incident response is a broader activity, and much more under the team’s control than the term “chaos” would suggest.
Take a listen for more interesting details about incident response processes that have worked at Google.

La Guerra Asimétrica del Dictador Hugo Chávez: Contra Comunicadores Sociales y Medios en el 2006
Eladio Rodulfo Gonzalez, Periodista Venezolano, publica una Investigación contentiva de varios tomos, donde recopila las Agresiones, Violaciones de Derechos Humanos y Asesinato de Comunicadores Sociales en el Ejercicio de su Profesión, por parte de los Gobiernos Dictatoriales de Hugo Chávez y Nicolás Maduro, aqui comparto el Tercer Tomo: Año 2006
Ese año, según los registros de Espacio Público hubo 151 violaciones a la libertad de expresión, cifra superior en 4,9% a las de 2006.Venezuela fue colocada en la zona marrón en materia de violación de la libertad de expresiónSe acentuaron las agresiones contra los medios y los comunicadores sociales.Hasta el cansancio el dictador repitió que su gobierno no renovaría la concesión a Radio Caracas Televisión, a pesar de que ésta no fenecía en 2007.Fueron constantes las amenazas de muerte contra periodistas por informar sobre hechos de corrupción.La Sociedad Interamericana de Prensa y otras organizaciones internacionales mostraron su preocupación por las violaciones de la libertad de expresión de parte de factores gubernamentales.Un tribunal prohibió a los medios publicar información sobre el Caso Anderson.Ese año el gobernador del Estado Bolívar le declaró la guerra a Correo del Caroní, de Ciudad Guayana, por informar sobre hechos de corrupción debidamente probados por los tribunales, pero que su régimen quería invisibilizar. Inclusive amenazó con demoler el edificio del diario, aunque éste disponía de los respectivos documentos de propiedad.

A serious crash by a delivery drone in Switzerland have grounded the fleet and put a partnership on ice. Within a stone’s throw of a school, the incident raised grim possibilities for the possibilities of catastrophic failure of payload-bearing autonomous aerial vehicles.
The drones were operated by Matternet as part of a partnership with the Swiss Post (i.e. the postal service), which was using the craft to dispatch lab samples from one medical center for priority cases. As far as potential applications of drone delivery, it’s a home run — but twice now the craft have crashed, first with a soft landing and the second time a very hard one.
The first incident, in January, was the result of a GPS hardware error; the drone entered a planned failback state and deployed its emergency parachute, falling slowly to the ground. Measures were taken to improve the GPS systems.
The second failure in May, however, led to the drone attempting to deploy its parachute again, only to sever the line somehow and plummet to earth, crashing into the ground some 150 feet from a bunch of kindergartners. No one was hit but this narrowly avoided being a worst-case scenario for the service: not just a craft failing, but the emergency systems failing as well, and over not just a populated area but immediately over a bunch of children. The incident was documented last month but not widely reported.
Falling from a few hundred feet, the 12-kilogram (about 26 pounds) drone and payload could easily have seriously injured or even killed someone — this is why there are very strict regulations about flying over populated areas and crowds.
Obviously they grounded the fleet following this incident and will not spin up again until Matternet addresses the various issues involved. How was it even possible, for instance, that the parachute line was capable of being cut by something on the drone?
IEEE Spectrum first noted the news stateside. The company the following statement on the matter:
This is the first time ever that our vehicle parachute system has failed. As stated in the report, the flight termination system was triggered nominally per the drone’s specification, but the parachute cord was severed during the parachute deployment.
At Matternet, we take the safety of our technology and operations extremely seriously. A failure of the parachute safety mechanism system is unacceptable and we are taking all the appropriate measures to address it.
Swiss Post and Matternet reacted to the incident immediately by grounding all the operations involving this vehicle type. Our experts analyzed the incident and proposed the appropriate mitigations which are being evaluated by FOCA. We will restart operations once Matternet and Swiss Post, FOCA and our hospital customers in Switzerland are satisfied that the appropriate mitigations have been applied.
Drone delivery is a promising field, but situations like this one don’t do it any favors when regulators take a look. Despite sunny predictions from the industry, there is a huge amount of work yet to be done in terms of flight proving the technology, and although 2 failures out of some 3,000 may not sound like a lot, if one of those failures is an uncontrolled fall that nearly takes out some kids, that could set the entire industry back.
(This story has been slightly updated to accommodate a new statement from Matternet.)
