24. Challenges / lessons learned
Things to do Things to avoid
• Make mock-ups FIRST • Stay out-of-control
–
–
–
Mobile apps have no set expectation
?
You can’t predict what will work
Do extensive user testing
?
– With mobile, the user is in control
– You can’t manage his device. Forget it.
– Give users tools so they can DIY.
– Be prepared to change your concept • Avoid the bigger picture
– Technical POC alone is not enough – Focus on a concrete function with an
immediate value add for the user
• Use the internet & its protocols
–
–
A mobile does not live in your network
?
VPN’s are a thing of the past
?
– Trying to change work processes,
integrate with business intelligence,
cover a larger scope: it will all fail
– Mobile is new: create demand first
– SOAP is nice when critical, XML is easier – When it’s time for the bigger picture,
– Use the universal firewall bypass port (80) current technology will be obsolete
• Think Multi-platform • Translate the web to mobile
– In some cases, mobile websites are OK
– 1 platform only is not realistic
?
– When you can: move up an abstraction layer
or two (but web browser might be too thin)
?
– But: don’t just convert existing web tools
– Mobile has a different usage model then
fixed (“browsing” is done on a desk)
