[IxDA Discuss] Article on Number of Usability Test Participants

2009-10-01 Thread Chris Ryan
I have been looking, unsuccessfully, through back issues of interactions 
magazine for an article, published a few years back, written I believe by 
someone from Microsoft as part of a debate about statistical significance in 
usability testing. There was something of a debate about testing with large 
numbers of users, and this article, as I recall, made an eloquent case for 
sticking to six to eight participants. Does anyone remember this? Perhaps I'm 
wrong in recalling that it was in interactions.

Re: [IxDA Discuss] Office 2007 in 2006, two years later

2008-11-02 Thread Chris Ryan
I've been curious, since the release of Office 2008, whether the
absence of the ribbon is due to a reconsideration of its value,
or simply the result of a different group within Microsoft having
developed the suite for Mac OS X.

Regardless, I'm not sure what the Mac Business Unit at MS might have
been up to between 2004 and 2008. Very little has changed, and the
integration with OS X is so poor (it often feels like you're working
on a different platform) that I avoid using it whenever possible.
iWork is a joy to use, in comparison.

Yes, Will, I know; that's why I wrote that I didn't know whether the
absence of the ribbon from Office 2008 was the result of a different
group within Microsoft having developed the suite for Mac OS X. I
tend to think that the software is better in general for having been
done by the Mac BU (does anyone remember the Word 6 port from
Windows?), but it's still nowhere near a standard Mac user
experience.

[IxDA Discuss] Interaction Design Specification Sites

2008-08-11 Thread Chris Ryan
There¹s been a fair amount of discussion here about documentation formats
and software used to produce wireframes, prototypes, and so on. But how do
people manage an entire specification? I have been using a hand-coded
intranet site, controlled via subversion; but my team is growing and I¹m
considering other ways to manage the information. Web access and formats
(not, for instance, Word documents) and some sort of version control are my
main requirements, along with relative ease of editing. What do people use?
Blogs, wikis?

[IxDA Discuss] Progress and Delay Indication for Varying Performance

2008-03-11 Thread Chris Ryan
There has been a fair amount written over the years about how to give  
good feedback for delays of varying lengths. However, what if your  
application has somewhat unpredictable performance (I won't get into  
the reasons here; suffice to say it is not sloppy implementation),  
where a given operation may complete quickly, or at other times result  
in a significant delay? Is there anything that could, or should, be  
done to establish this variability with the user without their giving  
up due to a perception that things may be even more variable than they  
actually are? On the other hand, might simply tailoring the type of  
feedback to the length of delay on the fly confuse users as they will  
never be sure what to expect?

Any ideas?


Thanks,

Chris
