INTRODUCTION

Oracle’s full lifecycle method for deploying

The Oracle® Unified Method (OUM)’s Implement Focus Area contains a
comprehensive set ofmaterials to support the development and implementation of
Oracle-based business solutions. However, with so much important material
included in OUM, it is easy for practitioners to become overwhelmed and not be
able to isolate and comprehend the core of OUM’s approach to software
implementation.

Oracle-based business solutions.

The Implement Core Workflow was created to identify the coreactivities and tasks
within the Implement focus area. This view should serve to accelerate the
understanding of OUM by new practitioners and help to keep project teams
focused on these tasks. The Implement Core Workflow also highlights the tasks
that are at the heart of the Implement focus area. These are the tasks that are
essential to many of the projects that are supported by OUM.
One ofthe philosophical underpinnings of OUM is to make the method serve you,
rather than serving the method. In order to accomplish this, OUM adopts the
philosophy of “building up” a workplan rather than “tailoring down”. The
Implement Core Workflow provides a good starting point for building up a project
workplan.
Finally, the Implement Core Workflow helps keep project teams focused on theessentials — the most important pieces of work that are required to be successful
on an OUM implementation project.

OUM is Iterative
Iterative - Indicates the number of times or
degree to which a task or task group
should be repeated, in order to increase
the quality of the work productsto a
desired level, add sufficient level of detail,
or refine and expand the work products
based on user feedback.

If the Implement Core Workflow were to be executed only once during a project,
OUM would be a “waterfall” method. It has been broadly recognized and
documented that the highest quality results, and lowest overall costs, can be
achieved using an iterative method. An iterativeapproach embraces requirements
change by building processes into the project that allow for refining requirements
while also maintaining a strong focus on cost and scope containment.
Since OUM is an iterative approach to implementing software systems, it is
essential that practitioners first understand the concepts of iterations. OUM’s
iterative approach asks that practitioners “Think a...
