Don’t Create Friction For 
Your Customers 
A Case Study on how a use a Service Design 
Project Sprint to help you make better decisions.
Background
In Kuala Lumpur the KLIA 
Express is the fastest way to get 
to the airport from the city and 
vice versa.
It costs Rm35 and only takes 28 
minutes.
This is how a ticket used to 
look.
You’d feed the ticket into the 
barrier machine and it would be 
returned to you once the barrier 
opened.
You needed to reuse the ticket 
at you destination station to exit.
It caused some queues at the 
exit barrier resulting in a delay 
for passengers.
This is what they use now.
No doubt that QR codes are a 
“newer” technology.
But do they make sense from a 
user perspective?
Do they make our lives any 
easier than the old system?
No.
It takes more time for you to 
scan the QR code at the barrier.
It may only take an extra 4-10 
seconds.
But if you have 100 people 
trying to exit at once, it adds up.
An extra 4 seconds per person 
results in more than a 6 minute 
delay for everybody on the train 
to clear the exit barrier.
As a user this delay is incredibly 
frustrating.
By installing QR Code tickets 
KLIA Express has created more 
friction for their customers.
Updating to a new technology 
without understanding how it will 
impact people…
…is a killer mistake that many 
people make.
QR codes are great, and 
incredibly useful if applied to the 
right problem.
But implementing them because 
they are “new” ends up creating 
a frustrating situation for your 
users.
And it probably cost them a lot 
of time and money to 
implement.
They basically spent time and 
money to create a service that 
is worse than before.
How could this have been 
prevented?
By taking a human centred 
approach to the problem.
They could have spent time 
observing how people use their 
service.
They could have prototyped and 
tested the use of QR codes.
They probably tested the 
technical feasibility of QR 
codes.
But not the usability and 
desirability from the users.
In less than a week they could 
have learnt that implementing 
QR codes would have no 
benefit to their users.
And moved their focus onto 
projects that could create a 
more positive impact.
The theory behind Human 
Centred Design is fairly simple.
The application can be hard.
Let us guide you.
Or if you don’t have the time let 
us do it for you.
We can do the work while you 
reap the benefits.
