Big changes ahead for India's IT majors

My article on challenges confronting the Indian IT majors was published in DNA in January 2015.

Here is the complete text of the article - Big changes ahead for India's IT majors:

Hidden among the noise surrounding the big three of the Indian IT industry - TCS, Wipro, and Infosys - was a very interesting sliver of signal that points to possibly big changes on the horizon. Though Cognizant should be counted among these biggies - based on its size and revenues - let's focus on these three for the time being.

Statements made by the respective CEOs of Infosys and Wipro, and the actions of TCS, provide hints on how these companies plan on addressing the coming headwinds that the Indian IT industry faces. Make no mistake. These are strong headwinds that threaten to derail the mostly good fairy tale of the Indian IT industry. Whether it is the challenge of continuing to show growth on top of a large base - each of these companies is close to or has exceeded ten billion dollars in annual revenues; protecting margins when everyone seems to be in a race to the bottom; operating overseas in the face of unremitting resistance to outsourcing; or finding ways to do business in light of the multiple disruptions thrust by cloud computing, big data, and the Internet of Things, they cannot continue in a business-as-usual model any longer.

Flipakart's Billion Dollar Sale, And A Few Questions

My article on Flipkart's Billion Dollar Sale and an article that appeared in a business daily on the preparations that went into it was published in  DNA on December 29, 2014.

This is the full text of the article:

A Billion Dollar Sale, And A Few Questions, by Abhinav Agarwal, published in DNA, Dec 29 2014
An article published on an online news portal (reproduced from a business daily) claimed that "Flipkart's 'Big Billion Day' was planned over more than 700,000 man hours (six months of work put in by 280 people over 14 hours every day) to get the back-end systems ready." This is a stupendous achievement by any yardstick, and all the more creditable given that Flipkart's infrastructure is nothing to scoff at to begin with, and which is rarely known to keel over during traffic surges. Despite all this preparation however, Flipkart didexperience issues during its big sale, which led to its founders issuing a public apology - an act of entrepreneurial humility that was well appreciated by many.

The article states that Flipkart "clocked a gross merchandise value (GMV) of $100 million". But what is "GMV"? According to Investopedia, Gross Merchandise Value, abbreviated as GMV, is "The total value of merchandise sold over a given period of time through a customer to customer exchange site. It is a measure of the growth of the business, or use of the site to sell merchandise owned by others." But there is some confusion as to what GMV actually means. This arises from the fact that GMV is not a standard accounting term. For instance, a search for "GMV" or for "Gross Merchandise Value" on the web site of The Institute of Chartered Accountants of India throws up zero results. GMV's definition differs based on each e-commerce vendor's assumptions. Therefore, if an item's price is marked at Rs 100, and Flipkart sells ten such items for Rs 70 each, is the GMV 700 or Rs 1000? Let us be generous and assume that GMV refers to the total sale value, before discounts - that would make it easier for Flipkart to claim they clocked in a hundred million dollars in GMV. Plus it is the logical thing to do - from a marketing perspective.

Vishal Sikka's Appointment as Infosys CEO



My article in the DNA on Vishal Sikka's appointment as CEO of Infosys was published on June 25, 2014.

This is the full text of the article:


Vishal Sikka's appointment as CEO of Infosys was by far the biggest news event for the Indian technology sector in some time. Sikka was most recently the Chief Technology Officer at the German software giant SAP, where he led the development of HANA - an in-memory analytics appliance that has proven, since its launch in 2010, to be the biggest challenger to Oracle's venerable flagship product, the Oracle Database. With the launch of Oracle Exalytics in 2012 and Oracle Database In-Memory this month, the final chapter and word on that battle between SAP and Oracle remains to be written. Vishal will watch that battle from the sidelines.

OBIEE Training Site

I was contacted by Seth Williams, who pointed me to this OBIEE training site - http://www.fireboxtraining.com/obiee-training, and asked if I would link to it. There is a an online tutorial, as well as a video, on how to create KPIs using OBIEE - How To Use KPIs | OBIEE Online Training Tutorial

I think this is useful, so am posting it to my blog - which, by the way, you would have seen is not being updated regularly. Feel free to browse to the site. Do let Seth and the people at Firebox know what you think of the site and the tutorial.

Disclaimer: I am not endorsing the site or the trainings. But you know that.

Junk Viz - When More is Less

There are examples of junk visualizations, and then there are examples of junk charts that just take your breath away.

The Indian news portal, FirstPost.in, which describes itself as a "trusted guide to the crush of news and ideas around you", published a story titled Shivraj set for massive victory in Madhya Pradesh: Survey | Firstpost, which has this chart (link to the image) - take a minute to study it. Then study it again. It is no optical illusion or card-trick being played here.

HBR and Junk Charts

Even the best can get it wrong. Only sometimes though, one hopes.
The venerable Harvard Business Review gets data visualizations horribly wrong. They have a post on Facebook where they contrast the costs of cancer treatment in the US and India.

The cost in the US is $22,000 on average, while in India it is shown as $2,900 (I would dispute this figure, as it looks very low).
The ratios is 7.58:1 (22000÷2900)

BI Mobile HD App 11.1.1.7

Finally got around to writing my long overdue post on the new BI Mobile HD app. To get on with it, without much ado, not to loiter, and all that... here goes.

The new BI Mobile HD app, version 11.1.1.7.0.2094, can be downloaded from the Apple iTunes App Store (link to app preview page on iTunes).
If you already have the BI Mobile HD app installed on your iOS device, you should get an App Store notification on the availability of an upgrade. Note, that since this version is available only for iOS version 6 (and above), if you are running an older version of iOS, you will not get a notification, and will not be able to download it. If you check the Wikipedia iPhone page (link) you will see that the iPhone 3GS and later devices support iOS 6. As far as the iPad device goes, if you check the Wikipedia page (link), iPad 2 and later devices support iOS 6.

Creating your first app with the BI Mobile App Designer

While creating sophisticated mobile apps that provide a rich feature set takes time, expectedly, what is wonderful about the recently launched Oracle Business Intelligence Mobile App Designer is the fact that you can be up and running without requiring a week-long training and a Master's degree in Computer Engineering.

Here's a short video I recorded on creating your first app with the BI Mobile App Designer (the direct URL on YouTube). A note of caution, and an apology of sorts - the audio in last few seconds of the video dramatically jumps up in volume. This is because I recorded these last few seconds later, and used different audio settings. I should have normalized it. I live, and I learn.


Introduction to the BI Mobile App Designer

Oracle launched a brand new addition to its Business Intelligence Mobile solution - BI Mobile App Designer, which lets you create stunning, interactive mobile apps, literally within minutes. Apps created run on mobile devices running a reasonably modern mobile browser - that can handle HTML5 and jQuery - and are available on both smartphone and tablet form factors.

White spaces and Map Views

When working with Map Views, you can choose to collapse the map formats panel on the left.

When you do that, the panel is hidden, but white space is displayed on either side of the map view, where the panel used to be.

Currently there is no option to remove this white space through a UI setting.

Using R to Unlock the Value of Big Data, by Mark Hornick


Using R to Unlock the Value of Big Data, by Tom Plunkett, Mark Hornick

This is a brief (approximately 80 pages) introduction targeted at users with an intermediate-level exposure of R and who want to get a quick look at working with R with Oracle's products. Strictly speaking, this is not an introduction to R, nor is this an R tutorial. It is, very specifically, an introduction to R as it integrates with and relates to the Oracle Database, the Oracle R Distribution, and the Oracle R Connector for Hadoop. The main chapters are "Using Oracle R Enterprise" and "Oracle R Connector for Hadoop", which have sixteen and seventeen examples, respectively, to help you get started.

Lying with Charts - Global Warming Graph

Global warming is a serious yet controversial enough topic without bringing in bad data visualizations practices into it. The Wonkblog on the Washington Post has an article titled, "You can’t deny global warming after seeing this graph". The post reproduces a chart prepared by the World Meteorological Association that plots global temperatures by decade. While the data shows that the last decade, 2001-2010, was the hottest on record, the graph uses a broken Y-axis that begins at 13.4°C instead of starting at zero. The chart does not hide this fact, and you can see that the chart's Y-axis starts at 13.4°C, but the most visually prominent piece in the graph is, well, the graph! And it screams the message that global temperatures are going off the charts - it's time to panic. There is no denying that we as a world need to get serious about investing in alternative and renewable sources of energy like solar, wind, and even nuclear, but this graph is just plain bad.
