An Agile Approach for Implementing Enterprise Software
Kevin Mann November 7th, 2013
A Look Back…
Before…
Longer lead times for delivering business value.
Now… Software releases deliver new business value every 1 to 2 months.
Page 2
A Look Back…
Before…
A significant proportion of features were rarely or never used.
Now… New features are highly anticipated by users and quickly adopted.
Page 3
A Look Back…
Before…
Releases were followed by large backlogs of change requests.
Now… Releases deliver the expected results without surprises.

A Look Back…
Before…
The project team was “locked-in” on specific program objectives.
Now… The team reacts quickly to unplanned changes in business priority.

The Digital Universe The measure of all digital data
created, replicated and consumed in a single year
= 40 Zettabytes
in 2020
CAGR = 42%
1 zettabyte = 1 thousand exabytes = 1 billion terabytes

Decision Point: Waterfall or Agile? ● New Program Objective: Deliver highest Business priority change
requests and defect fixes grouped as “Bundled Solutions”. ● Option 1: 3-phased waterfall program with fixed scope.
● Option 2: Agile / Scrum program with flexible scope.
Page 20
Phase 1: Aug 2011 to Apr 2012
Phase 2: Jan 2012 to Nov 2012
Phase 3: Aug 2012 to May 2013
Approx. 2 Releases per Quarter
8 Month Delay for any Business Value!
What is Scrum? Scrum in 100 words ● Scrum is an agile process that allows us to focus on delivering
the highest business value in the shortest time. ● It allows us to rapidly and repeatedly inspect actual working
software (every two weeks to one month). ● The business sets the priorities. Teams self-organize to
determine the best way to deliver the highest priority features. ● Every two weeks to a month anyone can see real working
software and decide to release it as is or continue to enhance it for another sprint.
