Annotated screen shotsBarriers to task completion on phone
Problem, Follow-up, Frustration, Urgency,ContextIt would have saved me a lot oftime in this mornings meeting if Icould have easily connected to anetwork fileshare, accessed the
powerpoint for our meeting andforwarded it out to the meetingparticipants..
I had to get onto my actual
computer at home to check thewebpage I originally wanted to
simply glance at on my phone.
Frustration: 4 (out of 5)Frustration: 2 (out of 5)
Needed to organize an event toattend this. doing it using the
phone was a bittoo much work
Send an email to bunch of folksto see how many are interested in
attending
Frustration: 4 (out of 5)
It's a link to an article that I knowwill have a lot of text. I decided towait until I'm at a desktopcomputer with a larger screen.
I marked it as unread on thephone; followed up by reading atmy desktop.
Frustration: 4 (out of 5)
I couldnt view theattachments on the phone soneeded to wait until I was back tomy PC
I made a mental note to look atthe attachments when I got back tomy PC.
