This webinar discusses the findings of a recently commissioned Forrester Consulting Total Economic ImpactTM (TEI) study of WANdisco's SVN MultiSite. Forrester's TEI methodology measures costs and cost reduction and weighs the enabling value of a technology in increasing the effectiveness of overall business processes. The subject of the study was a Fortune 500 company with annual revenues of over $5 billion, with SVN MultiSite in production in the US, UK, and India. Forrester concluded that SVN MultiSite generated a return on investment (ROI) of 357% with a payback period of less than 2 months.

Forrester Captured The Customer’s Experience
› Forrester interviewed WANdisco’s customer:
• Referred to as Computer Software Architects (CSA).
• Interviewed CSA’s Director of Global Software Engineering.
› CSA’s commercial software business:
• Generates more than $1 billion in revenue annually.
• Developer productivity is a mission critical concern.
• Developers follow standard processes and tasks.
› CSA developers must:
• Access the same source code.
• Devise solutions to complex problems.
• Synchronize development and debugging.
• Keep pace with development schedules.

9. © 2013 Forrester Research, Inc. Reproduction Prohibited 8
CSA wants to eliminate roadblocks to the productivity of
developers and protect intellectual property
Developers lose productivity
during builds and debugging
because of latency.
Developers lose productivity
when servers go down
Developers get distracted from
building software by problems
such as backup and recovery

10. Key Priorities For CSA’s Executive
© 2013 Forrester Research, Inc. Reproduction Prohibited 9
“We try to keep developers developing.
“We don’t want them to feel that they are limited in
the tools that they can use or become preoccupied
with activities that should be behind the scenes,
such as processes for backing up or restoring data.
“We want to protect the productivity of our
developers.”
Director, Global Software Engineering

CSA experienced the following benefits from using SVN
MultiSite from WANdisco
Increasing developer productivity
by reducing latency.
“Time spent waiting for builds
reduced from 10 to 1.5 hours.”
(Increased productivity by $4.4M)
Increasing developer productivity
during debugging.
“Increased developer productivity
during debugging by 10%.”
(Increased productivity by $909K)
Recovering same-day work after
server outages.
“Recovery of same-day work saves
24,583 developer hours annually.”
(Increased productivity by $442K)
Avoiding purchase of real-time
backup solution.
“We avoid purchasing a real-time
backup solution by using replicated
nodes to restore source code.”
(Avoided cost of $648K)

12. “Multiple nodes mean multiple potential points of connection. If one node or
site is unavailable, users can continue to use the system by connecting to
one of the other five nodes. This prevents lost developer hours and
reduces the impact of mistakes.”
(Director, Global Software Engineering)

13. “Globally located nodes put source code closer to people working on it. As a
result, check-ins between development teams get held MUCH more frequently
and granularly. This prevents IP loss at the local level when computers crash, get
corrupted, or when developers inadvertently delete files.”
(Director, Global Software Engineering)

14. “A significant amount of productivity loss occurs when a server goes down.
The work done by developers on that same day is almost always a
complete loss. We can recover the same day work with SVN MultiSite.”
(Director, Global Software Engineering)

15. CSA benefits from the ability of SVN MultiSite to:
• Rollback updates to previous versions of code.
• Research the history and changes made to code.
• Identify errors in methods or decisions to avoid further repetition.
• Isolate sabotage on the rare, but inevitable, occasions that it occurs.

“I attend a lot of webinars, but leave most of
them after 5-10 minutes. Repeatedly,
WANdisco seems to present more valuable
content than others. WANdisco has its finger
on the pulse of the industry.”
