- Accumulo — NSA’s BigTable implementation, released as an Apache project.
- How the Robots Lost (Business Week) — the decline of high-frequency trading profits (basically, markets worked and imbalances in speed and knowledge have been corrected). Notable for the regulators getting access to the technology that the traders had: Last fall the SEC said it would pay Tradeworx, a high-frequency trading firm, $2.5 million to use its data collection system as the basic platform for a new surveillance operation. Code-named Midas (Market Information Data Analytics System), it scours the market for data from all 13 public exchanges. Midas went live in February. The SEC can now detect anomalous situations in the market, such as a trader spamming an exchange with thousands of fake orders, before they show up on blogs like Nanex and ZeroHedge. If Midas sees something odd, Berman’s team can look at trading data on a deeper level, millisecond by millisecond.
- PRISM: Surprised? (Danny O’Brien) — I really don’t agree with the people who think “We don’t have the collective will”, as though there’s some magical way things got done in the past when everyone was in accord and surprised all the time. It’s always hard work to change the world. Endless, dull hard work. Ten years later, when you’ve freed the slaves or beat the Nazis everyone is like “WHY CAN’T IT BE AS EASY TO CHANGE THIS AS THAT WAS, BACK IN THE GOOD OLD DAYS. I GUESS WE’RE ALL JUST SHEEPLE THESE DAYS.”
- What We Don’t Know About Spying on Citizens is Scarier Than What We Do Know (Bruce Schneier) — The U.S. government is on a secrecy binge. It overclassifies more information than ever. And we learn, again and again, that our government regularly classifies things not because they need to be secret, but because their release would be embarrassing. Open source BigTable implementation: free. Data gathering operation around it: $20M/year. Irony in having the extent of authoritarian Big Brother government secrecy questioned just as a whistleblower’s military trial is held “off the record”: priceless.
Evolution from a research tool to a platform for patient engagement
Bruce Springer of OneHealth will speak about this topic at the Strata Rx conference. This article was written by Patrick Bane of OneHealth in coordination with Bruce Springer.
According to a recent study performed by the Jesse Brown VA Medical Center and University of Illinois at Chicago, patient-centered care has demonstrated positive outcomes on patients’ health, patients’ self-report of health, and reduced healthcare utilization. The study’s results are consistent with previous research that the patient-centered care model improves the quality of care while simultaneously lowering the cost of care.
OneHealth’s behavior change platform extends the patient-centered model by connecting members anytime, anywhere through mobile and web applications. Member generate data in their daily lives, outside of a clinical setting, which creates a much richer dataset of behaviors that are required to understand the patients’ condition(s), and their readiness to change. Members freely choose what to do and their choices actively generate data in five classes of information:
A video interview with Colin Hill
Last month, Strata Rx Program Chair Colin Hill, of GNS Healthcare, sat down with Dr. Dennis Ausiello, Jackson Professor of Clinical Medicine at the Harvard Medical School, Co-Director at CATCH, Pfizer Board of Directors Member, and Former Chief of Medicine at the Massachusetts General Hospital (MGH), for a fireside chat at a private reception hosted by GNS. Their insightful conversation covered a range of topics that all touched on or intersected with the need to create smaller and more precise cohorts, as well as the need to focus on phenotypic data as much as we do on genotypic data.
The full video appears below.
A tool for outreach to patients produces unexpected benefits
The traditional, office-based model for health care is episodic. The provider-patient relationship exists almost completely within the walls of the exam room, with little or no follow-up between visits. Data is primarily episodic as well, based on blood pressure reading done at a specific time or surveys administered there and then, with little collected out of the office. And even the existing data collection tools—paper diaries or clunky meters—are focused more on storing data that on connecting the patient and provider through that data in real time.
There is no way to get in touch when, for instance, a patient’s blood sugar starts varying wildly or pain levels change. The provider often depends on the patient reaching out to them. And even when a provider does put into place an outreach protocol, it is usually very crude, based on a general approach to managing a population as opposed to an understanding of a patient. The end result is a system that, while doing its best within a difficult setting, is by default reactive instead of proactive.
Business analytics projects: Using decisions as a basis to prioritize and identify requirements
Most normal people don’t look at data sets just for fun. They study views of the data to make decisions about what to do, be it a decision to take some specific action or a decision to do nothing at all. The main purpose of business analytics projects is to develop systems that turn large and often highly complex data sets into meaningful information from which decisions can be made.
The decisions that people make using business analytics systems can be strategic, operational, or tactical. For example, an executive might look at his sales team’s global performance dashboard to decide who to promote (tactical), which products need different marketing strategies (operational), or which products to target by markets (strategic). Generally speaking, all software systems that include an analytics component should enable users to make decisions that improve organizational performance in some dimension.
Modern data processing tools, many of them open source, allow more clinical studies at lower costs
This guest posting was written by Yadid Ayzenberg (@YadidAyzenberg on Twitter). Yadid is a PhD student in the Affective Computing Group at the MIT Media Lab. He has designed and implemented cloud platforms for the aggregation, processing and visualization of bio-physiological sensor data. Yadid will speak on this topic at the Strata Rx conference.
A few weeks ago, I learned that the Framingham Heart Study would lose $4 million (a full 40 percent of its funding) from the federal government due to automatic spending cuts. This seminal study, begun in 1948, set out to identify the contributing factors to Cardiovascular Disease (CVD) by following a group of 5,209 men and woman and tracking their life style habits, performing regular physical examinations and lab tests. This study was responsible for finding the major risk factors for CVD, such as high blood pressure and lack of exercise. The costs associated with such large-scale clinical studies are prohibitive, making them accessible only to organizations with sufficient financial resources or through government funding.
Long a development tool, TestFlightApp wants to move into analytics
For most iOS developers, TestFlightApp has become the go-to tool when they want to distribute a development build to testers. For those not familiar with the site, you can register applications, and then upload IPA files signed with either a development or AdHoc profile, either manually or using a desktop app that integrates directly into XCode.
Once uploaded, your testers can be automatically notified via email that there is a new version of the app available, and download it directly onto their device without having to use iTunes. It can even capture device IDs for new users (or new devices for existing users), and export them for use in the Apple developer portal.
You can also add code to have the running app check in with TestFlight. You can add “checkpoint” flags, ask survey questions (“why did you come to this page”), and have console logs and crash reports automatically uploaded to the site.
The problem is, once you’re ready to ship a production version, you have traditionally had to turn everything off and make sure that the Test Flight library was not linked in to the app. This has meant that there was no way to capture crash data from customers running the app. But now that’s changing.
Recently, TestFlightApp announced that it was now OK to leave the library in copies of your app uploaded to the App Store, and to have the app check in with TestFlight. Why the change? Probably because it is needed to support FlightPath, their new analytics tool. FlightPath seems to want to be the Google Analytics of mobile, allowing developers to see how customers use their app and offering demographic data.
FlightPath is likely to be the path that TestFlightApp takes to start monetizing their service. TestFlightApp has always been free, but there has been no pronouncement about whether FlightPath will follow that same model. It is currently in an open beta, so we may have to wait and see what the pricing model for the final product is. Of course, by then, all those beta users will have become hooked.
One major caution for people intending to keep TestFlight in their production code, watch out for leakage of private data! Many test builds spit out tons of information to the console. At times, I’ve had everything going back and forth to a server dumping itself onto the log. If you don’t disable that in the shipping code, you could be accidentally capturing all sorts of sensitive data, including credit cards, HIPPA restricted information, etc. So make sure that you have compiled out (or disabled) anything like that in the production build (which you can test with an AdHoc profile.)
A game changer for a marketer to pinpoint what a customer wants, when they want it, and how they want to hear about it
My 2 and a half year old daughter loves the Mickey Mouse Clubhouse. She watches episodes on TV and our iPad. She wears Minnie Mouse flip flops and giggles just about every time she sees anything with Mickey, Daisy, Goofy…you get the idea. And when she’s old enough to go to Disney World, Minnie might walk right up to her and say “Hi Jemma!” and give her a big hug.
Creating a personal interaction between a child and a beloved Disney character exemplifies the company’s recent initiative to deliver a personalized, hassle-free experience at their theme parks. 1 With the wireless tracking wristband ‘MagicBand,’ families are able to reserve spots in lines for popular attractions, purchase items at the parks, and unlock their hotel rooms. The MagicBand is part of the MyMagic+ system, which enables Disney to collect data on visitors’ purchasing habits and real-time location, among other things. Disney will use this vast trove of information to deliver a personalized experience at the parks and tailor marketing messages and promotions.
Learn to resist vanity metrics
One of the things we preach in Lean Analytics is that entrepreneurs should avoid vanity metrics—numbers that make you feel good, but ultimately, don’t change your behavior. Vanity metrics (such as “total visitors”) tend to go “up and to the right” but don’t tell you much about how you’re doing.
Many people find solace in graphs that go up and to the right. The metric “Total number of people who have visited my restaurant” will always increase; but on its own it doesn’t tell you anything about the health of the business. It’s just head-in-the-sand comforting.
A good metric is often a comparative rate or ratio. Consider what happens when you put the word “per” before or after a metric. “Restaurant visitors per day” is vastly more meaningful. Time is the universal denominator, since the universe moves inexorably forwards. But there are plenty of other good ratios. For example, “revenue per restaurant visitor” matters a lot, since it tells you what each diner contributes.
What’s an active user, anyway?
For many businesses, the go-to metric revolves around “active users.” In a mobile app or software-as-a-service business, only some percentage of people are actively engaged. In a media site, only some percentage uses the site each day. And in a loyalty-focused e-commerce company, only some buyers are active.
This is true of more traditional businesses, too. Only a percentage of citizens are actively engaged in local government; only a certain number of employees are using the Intranet; only a percentage of coffee shop patrons return daily.
Unfortunately, saying “measure active users” begs the question: What’s active, anyway?
To figure this out, you need to look at your business model. Not your business plan, which is a hypothetical projection of how you’ll fare, but your business model. If you’re running a lemonade stand, your business model likely has a few key assumptions:
- The cost of lemonade;
- The amount of foot traffic past your stand;
- The percent of passers-by who will buy from you;
- The price they are willing to pay.
Our Lean lemonade stand would then set about testing and improving each metric, running experiments to find the best street corner, or determine the optimal price.
Lemonade stands are wonderfully simple, so your business may have many other assumptions, but it is essential that you quantify them and state them so you can then focus on improving them, one by one, until your business model and reality align. In a restaurant, for example, these assumptions might be, “we will have at least 50 diners a day” or “diners will spend on average $20 a meal.”
The activity you want changes
We believe most new companies and products go through five distinct stages of growth:
- Empathy, where you figure out what problem you’re solving and what solution people want;
- Stickiness, where you measure how many people adopt your solution rather than trying it and leaving;
- Virality, where you maximize word-of-mouth and references;
- Revenue, where you pour some part of your revenues back into paid acquisition or advertising;
- Scale, where you grow the business through automation, delegation, and process.
