Survey Wisdom of Crowds� Business Intelligence Market Study 2016 Edition
Survey Wisdom of Crowds� Business Intelligence Market Study 2016 Edition
Im getting lazy on blog posts! Gotta change that! Taking a few days vacation but I promise Ill get back at it!
In the meantime, a request to, once again, participate on one of the most influential market studies for BI analytics - Howard Dresners Widsom of Crowds, 2016 edition.
Here are the details:
Welcome to the Wisdom of Crowds� Business Intelligence Market Study - 2016 Edition.
Qualified respondents that complete the survey will receive complimentary research for their personal use. This includes end users, IT and independent consultants.
Each section corresponds to an upcoming 2016 research report. The more survey sections that you complete, the more free research you will receive throughout the year!
Please note that this survey should take approximately 25-40 minutes to complete.
The objective of this study is to collect data on trends, vendors and products in Business Intelligence, Enterprise Planning and related markets. As a result we will be able to examine the realities, plans and perceptions surrounding these important markets. We will also rank vendors and products - creating an important tool for those seeking to invest in these solutions.
The underlying principle is this: the more data we collect, the more accurate the results.
This study is NOT sponsored by vendors (or anyone else) and none of your detailed data will be shared with the outside world. So, we respectfully request that you provide us with complete and accurate information - including your name, company, title and business email address.
For consultants: Please respond on behalf of a client or clients that you are working with.
Anonymous survey entrees cannot be accepted.
Thank you for participating. I am confident that this will provide an important and fresh perspective into the marketplace for all!
Sincerely,
Howard Dresner
Chief Research Officer
Dresner Advisory Services, LLC
Once again, heres the link to the Howard Dresners Widsom of Crowds Survey, 2016 edition.

Study on St Jude medical device security deemed “inconclusive” by University of Michigan researchers
Study on St Jude medical device security deemed “inconclusive” by University of Michigan researchers
A recent report that alleged security flaws in St. Jude Medical�s pacemakers and other life-saving medical devices has major flaws of its own. That�s according to a team of University of Michigan researchers who say they�ve reproduced the experiments that led to the allegations, and come to strikingly different conclusions.
The U-M team is composed of several leading medical device security researchers and a cardiologist from the U-M Health Systems Frankel Cardiovascular Center. �Hyperbolic� and �sloppy� are words they use to describe the unorthodox report, which was released last week by short-selling investment research firm Muddy Waters Capital and medical device security firm MedSec, Ltd.
The U-M team reproduced the error messages the report cites as evidence of a successful �crash attack� into a home-monitored implantable cardiac defibrillator. But they showed that the messages are actually the same set of errors you�d get if you didn�t have the device properly plugged in.
Through these wires, implantable defibrillators can perform sensing operations and also send shocks if necessary.
�When these wires are disconnected, the device generates a series of error messages: two indicate high impedance, and a third indicates that the pacemaker is interfering with itself,� said Denis Foo Kune, former U-M postdoctoral researcher and co-founder of Virta Labs.
On page 17 of the Muddy Waters report, a screenshot cites these very error messages as proof of a security breach.
�But really the pacemaker is acting correctly,� Fu said. �To the armchair engineer it may look startling, but to a clinician it just means you didn�t plug it in. In layman�s terms, it�s like claiming that hackers took over your computer, but then later discovering that you simply forgot to plug in your keyboard.�
Added Foo Kune, �While there still could be security problems, the screenshot is anything but supportive of the claim. When researchers with limited medical training go public with unvetted claims, it�s easy to jump to conclusions.�
Ethicists and other researchers have criticized MedSec�s technique of teaming with a short-seller to publicize its preliminary findings�and benefit financially, no less.
Short-selling is an investment practice that essentially involves betting that a particular stock will decline in value. If it does, then the investment firm profits. In this case, MedSec made a deal with Muddy Waters to receive a share of those profits. St. Jude�s stock fell sharply over the weekend.
�It was the irresponsible thing to do. Think about whether you believe everything a used car dealer claims when deciding whether to buy,� said Wenyuan Xu, a visiting professor of electrical engineering and computer science at U-M and an expert in automotive and medical device security. She recently hacked into Tesla�s autopilot system to demonstrate its vulnerabilities.
To conduct the experiments, the U-M team used a new and properly functioning model of the same defibrillator that the Muddy Waters study used�the Fortify Assura VR. In several additional instances, they found that the device operated properly.
Even while the U-M research team finds fault with the Muddy Waters report, they don�t mean to suggest that these medical devices�or any medical devices for that matter�are necessarily secure. They stress the importance of establishing security workflows early on in the design process of medical devices.
�While medical device manufacturers must improve the security of their products, claiming the sky is falling is counterproductive,� Fu said. �Healthcare cybersecurity is about safety and risk management and patients who are prescribed a medical device are far safer with the device than without it.�
Thomas Crawford, an assistant professor of medicine and a clinical electrophysiologist at U-M, agrees. Crawford implants and follows patients with pacemakers and implantable defibrillators.

�Given the significant benefits from home monitoring, patients should continue to engage in it via St. Jude Medical Merlin, and other companies� respective proprietary home monitoring systems, before independent research can substantiate the claims made by MedSec and their financial partner Muddy Waters Capital, LLC,� Crawford said.
Crawford adds that home monitoring has been shown to reduce a variety of adverse events, with some studies even showing reduction in overall mortality over periodic checks of devices in the doctor�s office. The devices can send actionable alerts to a central monitoring service, which then is forwarded to the physician, so that it can be dealt with immediately if necessary. Alerts include low battery status, potential malfunction of the device, or changes in heart rhythm, which may require treatment.
