Oracle Application Implementation Methodologies:
•
Oracle AIM 3.1 (Application Implementation
Methodology)
•
Oracle EMM (Easy Migration Methodology)
•
Oracle Unified Method (OUM)
Oracle AIM:
•
Oracle AIM is a methodology showing what
tasks are required, what order it should be completed in and what resources are
required
•
Oracle AIM provides templates for all the
tasks that require them.
•
The methodology is purpose built for Oracle
Applications and the detailed deliverables produced are designed with the
Oracle Application products in mind.
Oracle AIM Structure:
•
A phase is a chronological grouping of
tasks. It enables a flexible way to organize tasks, schedule major
deliverables, and deliver projects.
•
A process is a closely related group of
dependent tasks which meets a major objective. A process is usually based on a
common discipline.
•
A task is a unit of work, which results in
a single deliverable. I. e reports, schedules, code, or test results for
example.
Oracle AIM Process Flow:
Oracle AIM Project Phases:
•
An AIM project is conducted in phases that
provide quality and control checkpoints to co-ordinate project activities that
have a common goal.
•
During a project phase, project team will
be executing tasks from several processes
•
Oracle AIM Project Phases as follows (6
Phases)
–
Definitions
–
Operation Analysis
–
Solution Design
–
Build
–
Transition
–
Production
Oracle AIM Phases:
•
Definition
–
Plan the project
–
Review the organization's business
objectives
–
Evaluate the feasibility of meeting those
objectives under time, resource, and budget constraints
–
Emphasis is on building an achievable work
plan and introducing it with guidelines.
–
Strategies, objectives and approaches are
determined for each AIM process
•
Operations Analysis
–
Project team develops Business Requirements
–
Assess the level of fit between the
business requirements and standard application functionality.
–
Gaps are identified and corresponding
solutions developed.
–
Solutions for gaps evolve into detailed designs
during Solution Design.
•
Solution Design
–
Develop the detailed designs to meet the
future business requirements.
–
Project team members create detailed
narratives of process solutions developed during Operations Analysis
–
Supporting business requirements may
require building application extensions to standard features
–
The project team carefully scrutinizes
these solutions and chooses the most cost effective alternatives.
•
Build
–
Coding and testing of all customizations
and other custom software
–
Coding & testing of enhancements, data conversions, and interfaces
–
Policy and procedure changes relating to
business process modifications are developed.
–
Business system testing is performed to
validate that the developed solutions meet business requirements.
•
Transition
–
Deploys the finished solution into the organization
–
The project team trains the end users
–
Technical team configures the production
environment and converts data
–
Transition ends with the cutover to
production, when end users start performing their job duties using the new
system.
•
Production
–
It marks the last phase of the
implementation, and the beginning of the system support cycle.
–
The Information Systems (IS) personnel work
quickly to stabilize the system and begin regular maintenance.
–
Provide the ongoing support to the organization
for the remaining life of the system.
–
Compare actual results to project
objectives.
Oracle AIM Processes:
•
A process in AIM represents a related set
of objectives, resource skill requirements, inputs, and deliverable outputs.
•
A task can belong to only one process.
•
Project team members are usually assigned
to a process according to their specialization and background.
•

& Resource Management
–
Quality Management
& Configuration Management
–
Project Management itself is a
comprehensive process and has separate way to handle it, i.e. PMBOK , Oracle
PJM etc
•
Business Process Architecture
–
Task Code/ID : BP
–
Provide the framework
for combining change in business processes with implementation of software applications
–
It focuses on high-level business processes
and operations generally applicable to the organization
–
Make business
focused decisions either to change the current processes to
suit the application or to customize the application.
•
Business
Requirements Definition
–
Task Code/ ID: RD
–
Defines the business needs that must be met
by the implementation project.
–
Develop a complete set of business
requirements scenarios that can be used to map business requirements to
application functionality.
–
Analyze and identify the reporting
requirements for the business
–
Carefully document audit and control requirements
to satisfy financial and quality policies.
•
Business Requirements
Mapping
–
Task Code/ ID: BR
–
Ascertain the fitness for use of
application features in satisfying detailed business requirements expressed at
a business process step level.
–
Business Requirements Mapping encompasses
the following areas:
• Mapping
• Business system testing
• Application setups
–
Mapping is an iterative approach with the
following objectives:
• Prove
business process designs through demonstration
• Identify
gaps in the application
• Propose
feasible bridges to gaps
•

Oracle AIM Advantages:
•
Oracle's AIM is a proven approach for
implementing packaged applications. It comprises a set of well-defined
processes that can be managed in several ways to guide you through an application
implementation project.
•
AIM provides the tools needed to
effectively and efficiently plan, conduct, and control project steps to
successfully implement business solutions.
•
AIM defines business needs at the beginning
of the project and maintains their visibility throughout the implementation.
•
It defines internal, external, and time
sensitive business events and maps each event to the responding business and
system processes.
•
Client gains an accurate understanding of
the business requirements that need to be focused on during the course of the
implementation.
