Inference - "Significant"

Statistical Inference is all about using and applying the language of probability to say how trustworthy are you on the conclusions you make out of your data. When we talk about inferring from the data we naturally talk about the significance level. How significant is a claim on to the true side of a proposition? The simple idea is an outcome that would rarely happen if a claim were true is good evidence that the claim is not true.

"Significant" therefore in statistical sense necessarily does not mean how "important". It just simply means "not likely to happen just by chance" represented by an alpha  makes "not likely" more exact.

Now what kind of weird logic is that...LOL

Cigarette companies in their advertising campaigns have an internal rule that if they show a woman model smoking she needs to be of an average age of 25, realistically its always been lower than 25 as revealed by a famous statistic experiment through tests of Significance. I find this interesting. Was just discussing this that you can have knowledge of all statistics and formulas but its application to make sense in the real world is one of the forms of Godly Wisdom.

IT as a Innovation Partner in Business

Usually in Business organizations and especially in organizations where R&D is a separate department itself a tension persists on keeping the IT department away from any decision when it comes to innovation or process improvement. In short the IT department is generally seen as less of a help and more of a hindrance to innovation efforts. One of the main reasons is traditionally information systems are designed to impose structure on process, achieve pre-defined goals, produce metrics and minimize need for human interaction (in some case over maximize human interaction leading to nothing but "meetings").

While Innovation activities are highly unstructured and emergent, IT cannot be ignored or kept in isolation because IT can help in visualization tools, data mining efforts, uncover hidden relationships between data and create tools of knowledge management/information repository that so desperately is needed cross functionally but especially by the innovators within a org…

Analysis of SAP’s Platform Strategy

The software industry has been through high and lows up with the constant advent of new technological innovations and rapid changes in the global economic landscapes. SAP is the leading enterprise application software giant started by Hasso Plattner. The rise of Enterprise application industries started in early eighty’s with organizations needing one single software program that was capable of serving the multiple needs and functions of various departments. One single enterprise-wide application software means integrating applications that fused together for the smooth exchange and extraction of information. For example when customer services sold a product and got stock updated in the inventory by the warehouse people and the same data could be pulled by the Finance department. Enterprise Application software’s were designed exactly to do the latter mentioned processes seamlessly. SAP started by break away engineer’s Plattner and group build the company on strong engineering fort…

How Dashboards can mislead

Read an interesting article from John Shapiro professor at Northwestern Kellog on how dashboards can mislead executives and I cannot agree more. To be honest, I love visualization of data and have pushed my data architects and report writers to give me snapshots of various measures but how often the rich data didn't mean anything as it did not align with organizational goals. Even more, what information is important to me is not necessarily relevant to other executives in the organization.  Data analytics visualized on dashboards typically describe existing measures on past phenomena, some better ones predict future events and past data and the best one prescribe a course of corrective or strategic actions.

Shapiro talks about three types of traps executives can fall for:

1. The Context Trap:  We equate empirical data to the objective. I have blatantly used the cliche "numbers don't lie." But this belief can be dangerous because we can track wrong measures or metrics…
