Why Global e-Commerce giants are yet to conquer South East Asia



South East Asia (Popularly referred as SEA) is considered to be the most diverse & rapidly changing market in the world. With the population in excess of 650 million, the market is too huge to be ignored for any global player especially in the current booming space of online retail. In spite of this, we haven’t seen much of an activity from giants with likes Amazon, Alibaba & Rakuten in the region.

Let’s have a look at some interesting statistics.



Currently online shopping accounts for a minuscule number in the region. But with rapid penetration of internet & smart phones in the region the market is all set to explode. According to a report from Frost & Sullivan the region may see fivefold growth by 2018.

What is so very different about South East Asia?

1.       Six Countries six cultures:

Region comprises of 6 countries Singapore, Malaysia, Thailand, Indonesia, Philippines, Vietnam. Each of these countries has a different population mix, different language, religion & culture. Which is an important indicator of product preferences of people.

2.       Cross border transactions:

Crossing international boundaries means customs clearances, which add the complexity of payments of duties for imports, legal regulations on imports & restricted items in a particular country.

3.       Online security & cyber theft:

      The region in past has experienced some severe cyber theft cases. In the absence of a cross border jurisdiction mechanism & gaps in regulations potential consumers deter from online shopping.

4.      Penetration of Credit cards: 

Credit card penetration in SEA region is only about 10%. Add to that skepticism of those not very open to share the card details online for the fear of fraud. As a result cash on delivery (COD) & AT transfers is the preferred mode of payments. Handling of cash payments presents a bigger challenge than anything else. In most of the countries postal networks are either sluggish or unreliable. This means retailers need to have sophisticated delivery partners or build an in-house delivery capabilities.

5.       New sales channels:

With rapid penetration of social media & messaging services like “Line”, home grown e-retailers have already entered into strategic tie ups with the companies for exclusive promotions & campaigns in the region.

With above factors being critical to be successful in the region, even if likes of Amazon, Alibaba enter the market, it will take considerable amount of time for these companies to replicate the local knowledge acquired by home grown online retailers
In spite of all the factors SEA may still prove to be a market big enough for several large e-retailers to co-exist. However will it be profitable for these businesses, time only will answer that question.

iOS Vs. Android: Clash of the Titans


One of the hottest & most debated topics in the tech circle. Who is the winner? 

According to Apple Inc. iOS is an easy-to-use interface, with amazing features and security at its core. iOS is the foundation of iPhone, iPad and iPod touch. It’s designed to look beautiful and work beautifully, so even the simplest tasks are more engaging. And because iOS is engineered to take full advantage of the advanced technologies built into Apple hardware, your devices are always years ahead — from day one to day whenever.

According to Google Inc. Android is the operating system that powers more than one billion smartphones and tablets. Since these devices make our lives so sweet, each Android version is named after a dessert. Whether it's getting directions or even slicing virtual fruit, each Android release makes something new possible. 

We always hear from technology experts about the features, designs, app store, ease of use  etc. So we thought we will bring you an opinion from a end user prospective. Here you go.

Case Study: Applying Six Sigma to Cricket

Case Study: Applying Six Sigma to Cricket



Mike was the best batsman in the Club Acme cricket team. The probability of Club Acme’s winning a match was higher when he batted well and scored more runs. His batting form had been declining the past few months, however,affecting the team’s win percentage and revenues. Improving Mike’s consistency with the bat would help the team win more matches. The team hired a Lean Six Sigma Black Belt to analyze the factors affecting Mike’s batting and develop an improvement plan. A project team was formed with the chief batting coach as the project leader.

Problem Statement
The average number of runs scored by Mike per inning was 32.5 for the last 50 matches (January 2011 to December 2011) compared to his benchmarked 40 runs per inning. Team won only 36 percent of the matches they played in the same timeframe. (See Figure 1.)

Process Capability
Forty runs in a completed inning was the benchmark and set as the lower specification limit (LSL) for assessing process capability. Any complete innings in which Mike scored fewer than 40 runs was considered a defect. Mike played 50 matches in 2011 and as he usually batted at the top of the batting order, he was dismissed in all 50 matches. He scored more than 40 runs in only 14 out of 50 innings.


Figure 1: Run Chart of Runs

Batting Statistics for Mike in 2011


The project team determined the improvement target by using the 1-sample percent-defective test


Figure 2: Summary of 1-Sample Percent Defective Test

The 1-sample percent-defective test compared Mike’s current defective rate to a target of 50 percent. With a 0.05 level of significance and a calculated p-value of 0.001, the test verified statistically that Mike’s current percent defective was greater than 50 percent. At a 90 percent confidence level, the true percent defective was between 59.74 percent and 82.21 percent. (The confidence interval (CI) quantifies the uncertainty associated with estimating the percent defective from the sample data.) The team concluded that if Mike scored 40 runs or more in 50 percent the matches played, it would be a statistically significant improvement.

Root Cause Analysis of Batting Performance
The team analyzed data for all of the innings in which Mike scored fewer than 40 runs. In 30 out of 36 defective innings (83 percent), Mike was dismissed for fewer than 20 runs. Once Mike crossed 20 runs, the probability of playing a longer inning was high – he was dismissed only 6 times between 20 and 40 runs out of the overall 50 completed innings. Why was Mike dismissed so often before scoring 20 runs?

The team used a Pareto chart to identify the dismissal types when:
 Mike scored fewer than 20 runs
 Mike scored more than 20 runs



Figure 3: Types of Dismissals for Innings with Fewer Than 20 Runs

Figure 4: Types of Dismissals for Innings with More Than 20 Runs

Being caught behind was the most frequent cause for dismissal when Mike scored fewer than 20 runs: 50 percent compared to 10 percent when he scored more than 20 runs. Why was Mike getting caught by the keeper and the slip fielders so often at the start of his innings? Club Acme’s statistician provided the shot data for Mike as shown in Figure 5.


Figure 5: Type of Stroke Relating to Type of Shot Played 
(Left = Type of Stroke, Right = Attacking Shot Played)

Of Mike’s caught behind dismissals at the start of his innings, 67 percent occurred while he was playing attacking strokes. In particular, the attacking shots (a subset of attack strokes) that contributed most often to the caught behind dismissals were three types of high-risk shots: hooks, pulls and upper cuts. A Closer Look at the Shots The team analyzed the success of these shots played by Mike at the start of his innings and later in the games. By looking at Mike’s historical strike rate, it was clear that he used to play 25 balls to score 20 runs. The team tested the success of his hook, pull and upper cut shots during the first 25 balls played by Mike in comparison to shots played after 25 balls. The strike rate for balls 26 and higher was almost double compared to the first 25 balls. compared to 10 dismissals out of 28 attempts in the first 25 balls, Mike was dismissed just 4 times in 117 attempts after playing 25 balls.



The conclusion from this analysis was that Mike had to avoid playing those higher-risk shots in the initial stages of his innings.

Other Inputs for Batting
In a brainstorming session, the project team identified the various factors related to runs being scored and created the cause-and-effect diagram shown in Figure 6. Items highlighted in red are the ones deemed to be most critical and that were investigated further.


Figure 6: Factors Related to Runs Scored

The project team did not find any difference in Mike’s performance when batting first or when chasing a target. His performance on flat pitches, however, was better compared to green pitches. What was affecting Mike’s batting while playing on green pitches? The batting coach suggested the team look at the type of bat Mike used and his batting position. While the type of bat used (light or heavy) did not have any measurable impact, Mike performed better on green pitches when he was not required to open the batting (bat first) and face the new ball bowlers. On green pitches, his batting average in fourth position was 52.6 compared to 12.1 when Mike opened the batting, a statistically
significant difference (Figure 7).


Figure 7: Pitch Versus Batting Position
The project team collected data for Mike’s batting and shot selection against different types of bowlers. Shots played by Mike that did result, or could have resulted, in a dismissal were identified as false or risky and termed “defective.”
The proportion of defective shots was contrasted against the total number of balls played against each type of bowler. As shown in Table 3 and Figure 8, there were differences among the percent defectives for different bowling types at a 0.05 level of significance (p-value: 0.000). From the analysis, it was concluded that Mike played more false or risky shots while playing left-arm seam bowlers (21.48 percent) in comparison to other bowlers such as right-arm seam
bowlers and spinners.




Figure 8: Percent Defective Comparison Chart
The chief batting coach analyzed video footage of Mike batting against left-arm seam bowlers. Mike played a left-arm seam with a closed stance, similar to what he used for right-arm seam bowlers. The orthodox stance blocked him before he played a shot, and he ended up playing around his front pad (protective clothing). He also kept his back swing too straight, playing across the line (moving laterally to the incoming ball) and ended up chest-on to the ball.

Mike was advised to play left-arm seam with an open stance and wider back-lift. With an open stance, he could better align himself up to the incoming ball. For a wider back-lift, he had to pick his bat over the off stump or the first slip area (angle of the bat while playing the ball changes depending upon the starting position of the bat) rather than over the middle stump.

The Improvement Plan
After the analysis was complete, the project team summarized its results and made its improvement
recommendations for Mike and Club Acme.

Table 4: Action Plan



Project Outcome and Benefits
The action plan recommended by the Black Belt and the project team helped improve Mike’s batting consistency. He scored an average of 49.32 runs per inning in the 28 innings of the first six months of 2012 compared to his previous baseline average of 32.52 runs per inning, as shown in Figure 9. In addition, Club Acme improved its win rate to 54 percent (16 out of 28).
