Agile Offsharing makes a radical step
Conventional approach:Minimize the need for
communication("Reduce coupling!")
Agile Offsharing approach:Actively increase the need for
communication("If it hurts, do it more often!")

Details
Agile Offsharing is not for everybody
Preconditions:
• Modest time zone difference
• Limited cultural difference• both national and
SW development culture
• Low-enough language barrier• for enough team members
• Volunteer team members
• Reliable, low-latency network connectivity
Steps for use:
• Setup & try out DPP tooling
• Find volunteers
• Select tasks & form pairs
• Do DPP
• Reflect on DPP sessions
Can only be worked outby technology transfer

Why is Agile Offsharing needed?
Lutz Prechelt, Freie Universität Berlin
We tend to under-estimate what needs explanation:

1 Knowledge about Pair Programming (PP)
• Research on conceptualizing the PP process since 2004• on real industrial sessions
• Goal: Find helpful behavioral patterns and antipatterns
• Results so far:• Base concepts
• Roles• e.g. Spokesperson, Watchman,
Guide/Robot, Task expert/Mentee
• Knowledge transfer mechanisms
• e.g. Clarification Cascade

2 The Saros DPP tool
• Distributed IDE• Plugin for Eclipse, soon also for IntelliJ IDEA• In development since 2006, Open Source• Industrial strength
• >1000 downloads per month

2 The Saros DPP tool
11 / 12
Knowledge about Distributed-Pair Programming (DPP)
• Research on conceptualizing the DPP process since 2010• builds on the PP research
• Goal 1: Find helpful behavioral patterns and antipatterns• Coping with
limited awareness• Making sensible use of
concurrent editing
• Goal 2: Validate usefulness
• Results so far:• Effortless awareness
bridging (Eclipse dialogs)• Prudent, limited use of
concurrent editing• DPP can be as efficient as
PP – or even slightly more

4 Agile Offsharing trials
• Just starting, with Lithuanian outsourcing provider NFQ• builds web applications
with long-term customers
• NFQ funds our full-time group member Holger Schmeisky• since 2014-04
• Also: In discussion with 2 large multinationals• we expect to start trials at
one of them later this year
