Tactical Logic: February 2009

http://tactical-logic.blogspot.com/2009_02_01_archive.html

Information Engineering for the Practical Data Phreak. Friday, February 13, 2009. Appropos of "Murphy's Laws of Data". I find it useful to imagine that data is created by a little deamon and his job is to make me look like a durn fool. Subscribe to: Posts (Atom). View my complete profile. Insight plus optimization beats either alone. If you can get significant results from random data, you're doing something wrong. Information is to data as data is to hardware. Links: Things to Read. Papers: Stuff I write.

Tactical Logic: February 2008

http://tactical-logic.blogspot.com/2008_02_01_archive.html

Information Engineering for the Practical Data Phreak. Friday, February 29, 2008. A Missing Profession: Information Engineering. In business intelligence it seems to me like there is a missing profession: information engineering. Business Intelligence (BI) solutions ultimately aren't about the data that an organization has: they are about the information that the data carries. This information has to be uncovered, it has to be validated, and it has to be refined in a way that is usable. Information, like...

Tactical Logic: Customers are Weird

http://tactical-logic.blogspot.com/2009/06/customers-are-wierd.html

Information Engineering for the Practical Data Phreak. Saturday, June 27, 2009. Really, really weird. Imagine a company with 2mm customers. Reasonable-sized, not huge. How many people do you know well? Think about the absolute weirdest person you know. That company has customers that are literally 100 times weirder than the weirdest person you know. In fact, they've got 200 of them. It's a bad idea to think you know what customers are going to do without testing, measuring, and finding out.

Tactical Logic: Bozoing Campaign Measurements V

http://tactical-logic.blogspot.com/2009/06/bozoing-measurements-v.html

Information Engineering for the Practical Data Phreak. Saturday, June 27, 2009. Bozoing Campaign Measurements V. Here's a classic: toss all negative results. Clearly, everything we do is positive, right? Nope Anything that can have an effect can have a negative effect. I've seen an interesting variant on this technique from a very well-paid consultant. Said VWPC analyzed 20 different campaigns and reported extensively on the one campaign that had results that were significant at a 5% level. Gap Minder Da...

Tactical Logic: March 2008

http://tactical-logic.blogspot.com/2008_03_01_archive.html

Information Engineering for the Practical Data Phreak. Monday, March 31, 2008. The Secret Laws of Analytic Projects. The First Certainty Principle: C 1/K. Certainty is inversely proportional to knowledge. A person who really understands data and analysis will understand all the pitfalls and limitations, and hence be constantly caveating what they say. Somebody who is simple, straightforward, and 100% certain usually has no idea what they are talking about. The Second Certainty Principle: A C. Bad analysi...

Tactical Logic: May 2009

http://tactical-logic.blogspot.com/2009_05_01_archive.html

Information Engineering for the Practical Data Phreak. Sunday, May 31, 2009. Statistics and DBA work really are two different disciplines, although from the outside we're both numbers people. I've learned the hard way that there's a lot. That I don't know about how to set up a database. Likewise, I've had some database people push some very strange ideas about how to do analysis. Don't you want the most current data possible? Bozoing Campaign Measurements - III. We're taking about doing basic reporting o...

Tactical Logic: July 2009

http://tactical-logic.blogspot.com/2009_07_01_archive.html

Information Engineering for the Practical Data Phreak. Sunday, July 12, 2009. Bozoing Campaign Measurements VI. And the hits keep coming. This story involves a tracking database. The database was tracking long-running campaigns, where the process was that a customer 1) contacted the company via customer care 2) at that point, was randomized on a by-campaign basis. Once there was customer activity, that customer was tracked for three months. Subscribe to: Posts (Atom). View my complete profile. If you can...

Tactical Logic: Bozoing Campaign Measurements - III

http://tactical-logic.blogspot.com/2009/05/bozoing-measurements-iii.html

Information Engineering for the Practical Data Phreak. Sunday, May 31, 2009. Bozoing Campaign Measurements - III. I've got another story from the customer cross-sell system I was talking about in Bozoing Measurements I. We're taking about doing basic reporting on the system. Remember, we're keeping out a control group. We were changing the control group process from keeping out individual control groups per each campaign (which caused a lot of problems actually - more in a later post). Information is to ...
