This chord diagram shows relationships in terms of switching behaviour among phone brands.
The chords are directed: for example, while 8.7% of respondents who now have a Samsung used to have a Nokia, only 1.2% have the opposite; 1.2% now have a Nokia and used to have a Samsung phone.
The thickness of chords between brands encodes the percentage of respondents that switched between two brands: thicker chords represent a higher percentage of respondents that made that switch.
This diagram reveals asymmetries: if a chord is tapered, there are more respondents switching to one brand from the other than vice versa.
Mouse over a brand name to focus on switching behaviour to and from other brands concerning that specific brand.
While almost everyone in the Netherlands has a phone, many consumers switch to a new phone whenever their contract allows it. But how do people switch? And how does this differ per brand? To understand the complete flows of people switching phone brands (or staying loyal) we have analysed the connection between the respondent's current and previous main phone brand by visualizing the data in the Chord Diagram above. The chord diagram's outer ring represents the current main brand shares of all the respondents while the chords help to show what the brand of the previous was used to be.
The circle is split up into 8 brands with the arc length of each group scaled to the current brand’s market share. The percentages along the outer rim of the chord Diagram give the share-per-brand. This shows that Samsung dominates the installed base with a 38% share, Apple is 2nd with 19% and Nokia is 3rd with 16%.
The chords between the arcs visualize the switching behaviour of the respondents between brands in both directions. For example, the big dark blue chord connecting Samsung and Nokia in the lower left section shows the part of respondents that moved from Samsung to Nokia and from Nokia to Samsung. The figure shows that Nokia has lost its installed base share to Samsung, as 8.7% of all respondents that used to own a Nokia now own a Samsung. At the same time, only 1.2% of the Nokia owners previously owned a Samsung.
The color of the chord shows which brand has been the net gainer, thus the brand that managed to gain more customers from the connected brand than it has lost to this brand. With this in mind, we can see that Apple is a true net gainer; all its chords are 'Apple grey'. Even more so, besides the chord to Samsung, all chords at Apple are extremely thin at the other side, thus Apple has lost virtually no customers to other brands except Samsung.
There are also chords that connect each brand to itself. These 'hill-like' chords represent the respondents who did not switch brands, but stayed loyal to their brand.
Hover over a brand name or arc to see only the chords of that brand highlighted and an extra piece of information regarding that brand to the right of the Chord Diagram.
Note: This analysis refers only to respondents' main phone
When studying the flows between brands we can come to several interesting conclusions:
Since this is the 2nd year that we have created a Chord Diagram from the GMCS data, we can compare the years to find changes that have occurred since last year. Below you can see the Chord diagram from last year on the left and the one from 2014 (thus the same as the big one at the top of the page) on the right:
Several points stand out by comparing these two Chord Diagrams
These examples are a handful of the interesting facts that can be gained from the study. I encourage you to study the chord diagram by yourself to find even more insights and play with the interactive version. Finally, this analysis is but a small piece of the total report based on the yearly Global Mobile Consumer Survey - Netherlands Edition that Deloitte performed. Please feel free to contact any of the team members for more information or the complete report and also how you can discuss this with your clients.

Survey Deloitte has carried out the Global Mobile Consumer Survey – an annual snapshot of the mobile consumer, based on insights from more than 37.000 respondents in more than 22 countries. This analysis is based on the Dutch mobile market anno 2014, based on over 2000 respondents from the Netherlands, where this sample is nationally representative. All research has been undertaken via online research. Fieldwork took place between May to June 2014. The questions for this survey were written by Deloitte member firms. The multinational online research program was managed by Ipsos MORI.
