Collaboration tool for discussions
Web applications (form-filling, structured data)
Personal home pages, info, bookmarks
Sync to laptops and Palm devices

contribute, remote offices are on same playing field
– Push and pull – changes by email, or browse/search

Challenges of Distributed Teams
•

•
•
How to get a virtual team working together?
Conference calls & visits
Shared drives
E-mail
• Documents get lost, can’t search shared email space
• Internal newsgroups
• Great for discussion, but … not easy to search, hard to
find ‘final consensus’ of a thread
• Intranet sites
• Hard to update, ‘one webmaster’ syndrome
• Special tools and knowledge required

What is a Wiki?
• WikiWiki = The Writeable Web
– As quick to contribute as email,
as easy to use as a website

Perl:

How to use TWiki
• Use for knowledge capture about product and
technology
• Avoid overlap with other tools and processes
– <Customise this as necessary!>
– Don’t use to document Quality processes etc.
– Don’t duplicate official documents
• Good for rapid updates between document revisions, can feed
into official documents

TWiki Implementation
• Runs on <YourOS> server (http://your-twikiserver/)
– <Say that it’s backed up>
• Open Source, written in Perl
– Saves thousands of <YourCurrency> in software costs
– Customisation

– Rapid development
• Templates, access control, web applications, easier linking, …
– Plugin architecture
• Drawing, action tracking, voting, calendars, …

TWiki Issues
• ‘Don’t Touch’ syndrome
– looks like a ‘proper website’
– ‘better not touch it, so-and-so owns that page’
• ‘Unofficial’ syndrome
– <YourCompany status goes here – emphasise any
official support, and that server is backed up>
• Not always connected to intranet
– Can easily sync onto laptops and PDAs

TWiki Issues
• Time required to contribute
– Save time by doing less email, and finding critical info
quicker
– Save time by responding to FAQs with link to Twiki
– Learn new technology by taking notes on TWiki
– Keep useful URLs in TWiki – notes, ‘magnetic pages’
• TWiki syntax
– use the help pages, doesn’t take long to learn
• Forgetting passwords – use IE5 to store password

TWiki Issues
• Email Habit: It takes time to get used to
collaborating the TWiki way. "I prefer e-mail“
– Email doesn’t scale – new people, new technology,
new customers, new partners, …
– Getting the right information to right person -> happier
customers
• Ownership: Shared knowledge vs. ‘Owners’
"I don’t want to edit someone else’s page“
– Wiki culture: nobody ‘owns’ pages, and any change can
be built upon.
– First person to create page is not the owner!

Highlights: WikiWords for Linking
• Easy to create hyperlinks within TWiki pages
– Just use a WikiWord
• WikiWords are capitalized words, run together,
e.g. SmartCompanies, IntranetTools
• To create a new link, type:
– For more info, see IntranetTools.
• If the ‘IntranetTools’ page exists, it is turned
into a link:
– For more info, see IntranetTools.
Page 12
Highlights: Creating New Pages
• First, type in some text including WikiWord for new
page
– For more info, see IntranetTools?.
• The ‘?’ is a link (to a page that doesn’t yet exist).
• Now, to create the IntranetTools page, click on this
link, type in some text, then hit Preview and Save.
– If you return to original page and hit Refresh, the link
now covers the whole WikiWord:
– For more info, see IntranetTools.

Highlights: Version Control
• Pages are under version control:
– See previous page revisions.
• click on the r1.4 type links at bottom of page
– See differences between revisions.
• click on the Diffs link at bottom of page
– See who changed what and when.
• ‘Soft Security’ – anyone can change anything, but
changes are logged
Page 14
Highlights: Access Control
• Define groups and set access restrictions to webs
based on these groups
• Example TWikiAdminGroup page:
• Set GROUP = PeterThoeny, PaulReiber
• Set ALLOWTOPICCHANGE = TWikiAdminGroup
• Default – use Soft Security
• Special applications – use Access Control
