ORACLE UNIFIED METHOD (OUM) OVERVIEW
Oracle is evolving the Oracle Unified Method (OUM) to achieve the vision of supporting the entire Enterprise IT lifecycle, including support for the successful implementation of every Oracle product. You can tailor OUM to support your specific project situation. With its ready-made templates, guidelines, and scalable work breakdown structure, OUM provides the programmatic tools you need to manage the risks associated with your project.
OUM provides support for Application Implementation projects, Software Upgrade projects, and the complete range of technology projects including initial support for Business Intelligence and Enterprise Performance Management and deep support for Service-Oriented Architecture (SOA), Enterprise Integration, and Custom Software. Refer to the What's New? page for details on the features of this release.
OUM includes three Focus Areas – Manage, Envision, and Implement. OUM's Manage Focus Area provides a framework in which all types of projects can be planned, estimated, controlled, and completed in a consistent manner. OUM’s Envision Focus Area deals with development and maintenance of enterprise level IT strategy, architecture, and governance. Envision also assists in the transition from enterprise-level planning and strategy activities to the identification and initiation of specific projects. The Implement Focus Area provides a framework to develop and implement Oracle-based business solutions with precise development and rapid deployment.
In order to understand the connection between the artifacts produced in the Envision focus area and how they relate directly to the tasks in the Implement focus area you should review the Envision Touch Points.
The diagram below shows how the Envision, Manage, and Implement focus areas fit together to form OUM:
OUM couples the experiance of Oracle's global practitioners with and extended Unified Process - based framework. It provides this collection of best practices organized as a series of processes or workflows that can be assembled and scaled to achieve various information technology related business objectives. OUM also leverages Oracle’s intellectual capital by reusing processes, tasks, and templates from Oracle's complete portfolio of existing methods. For further reading on UP, see The Unified Software Development Process.
OUM also possesses the following properties:
- Focuses on the business to assure stakeholder acceptance and delivery of the development effort's values, goals, and objectives.
- Centers on architecture to provide a clear perspective of the whole system. During Inception and Elaboration, the objective is to define an executable architecture before committing resources to a full-scale development and implementation effort.
- Encourages adaptability and balance for scalable delivery across small and large projects possessing disparate resources and skill levels while assuring repeatable results.
- Provides rapid implementation techniques that enable building business solutions in short time frames.
- Uses non-proprietary and referential standards, such as the Unified Modeling Language (UML) and de facto standards like the Unified Software Development Process
hesitate to add, remove, or rearrange tasks, but be sure to reflect those changes in your estimates and risk management planning.
OUM is evolving. The vision is to support the entire Enterprise IT lifecycle, including support for the successful implementation of every Oracle product. Upcoming releases of OUM will provide enhanced support for Oracle's full complement of Enterprise Application suites including: product-suite specific materials and guidance for tailoring OUM to support various engagement types.
Your contributions and feedback are welcome and appreciated. Improvements to OUM continue to be made based upon the experience that Oracle acquires through its myriad of interactions with customers and users of Oracle's software products. Please contribute your thoughts, comments, ideas, and work products or artifacts to Oracle's Global Methods team so that we may continue to improve this body of work.

Why Use OUM?
More Focused Effort
OUM enables projects to clearly define business scope as well as the need to create enterprise business process models. This planning results in tighter scope control, more accurate business understanding, and a firm foundation for client acceptance.
By combining activities and tasks in different ways, OUM can be applied to many types of information technology software development and implementation projects.
Seasoned information technology practitioners representing years of experience have contributed their knowledge to OUM. Project teams can take advantage of this experience by leveraging these leading practices along with industry standards.
OUM subscribes to an iterative approach that incorporates testing and validation throughout the lifecycle, rather than testing for quality only at the end of the project.
More Cost Effective
OUM facilitates improved control of project expenses by using a flexible work breakdown structure that allows you to perform only necessary tasks.
Reduce Project Risk
Implementing an iterative, broadly applicable method mitigates requirements mismatch. A key focus of each iteration in OUM is to identify and reduce the most significant project risks. This ensures that the most critical risks are addressed as early as possible in the project lifecycle, which results in a measurable reduction of schedule and budget risks.
OUM has several key concepts and significant milestones that are used to manage the development cycle. These key concepts and milestones are demonstrated in the MS Project OUM Full Method Example Workplan. The example workplan provides a template for the phases, processes, milestones, and concepts used in a OUM project.
This section provides a brief overview of the following concepts and significant milestones used to manage a OUM project:
- Work Products
Projects based on OUM are carried out in an iterative fashion. Each iteration is concluded by the release of an executable product that may be a subset of the complete vision, but useful from some engineering or user perspective.
The OUM definition of an iteration is consistent with the Unified Process, but may be slightly different from the iterations in a CDM FT or DSDM-like approach. In OUM, the result of an iteration is an increment.
At the end of each iteration, the active set of work products or artifacts are released to form the current baseline. A release is therefore defined as a relatively complete and consistent set of artifacts – possibly, but not necessarily including a software build – delivered to an internal or external user. An internal release is used only by the development organization, as part of a milestone, or for a demonstration to users or customers. An external release is delivered to the end users.
A release is not necessarily a complete product, but can just be one step along the way, with its usefulness measured only from an engineering perspective. Releases act as a forcing function that drives the development team to get closure at regular intervals, avoiding the "90% done, 90% remaining" syndrome.
At each iteration, artifacts are updated and released. It is said that this is a bit like "growing" software. Instead of developing artifacts one after another in a pipeline fashion, they are evolving across the cycle, although at different rates.
In OUM, tasks are grouped into Activities. An activity groups “cross view” tasks together. Generally, activities do not cross phases. They occur as a group of related tasks within the phase that result in the completion of a substantial milestone or deliverable. Activities then are spread within the project phases according to the time and ordering where they occur during the life of the project.
One example would be all of the tasks that relate to gathering business requirements. Tasks from one process and one from another process are grouped into an Activity called Gather Business Requirements.
In OUM, the output of a task or activity is called a work product to eliminate the risk of having method deliverables confused with contractual deliverables. Contractual deliverables are specifically referenced in the contract and often have a payment schedule associated with their acceptance. Contractual deliverables may be method work products, but they may also reference additional deliverables not documented by the method.
In addition, not every work product referenced in the method material is required for a given project. The required work products are based on specific project scope. In this case, the "optional" work products are part of the OUM method material, but are not included in the project workplan.

Configuring MS Office Macro Security Settings
To assure trouble free operation of method materials, the macro security settings associated with MS Word and MS Excel must be modified. During product installation, the Microsoft install program establishes all MS Office components with the maximum security setting enabled. The affect of this setting is to prohibit the execution of any macro code instructions embedded in either an MS Word document or MS Excel workbook. Because method materials use extensive macro code, the MS Office security level options must be adjusted prior to utilizing the method pack.
To adjust the security level for MS Word 2003:
- Start Word.
- Navigate to Tools > Macro > Security…
- Select the Security Level tab and select the Medium radio button option. This option allows you to choose whether or not to execute macro code instructions.
- Select the Trusted Publishers tab and make sure that Trust all installed add-ins and templates and Trust access to Visual Basic Project at the bottom are checked.
- Click OK.
To adjust the security level for MS Word 2007:
- Start Word.
- Navigate to Office Button > Word Options > Trust Center > Trust Center Settings >.
- Select Macro Settings.
- Make sure that Disable all macros with notification button is selected in the Macros Settings and that Trust access to the VBA project object model is in the Develop Macro Settings.
- Click OK twice.
- Exactly the same procedure must be performed with MS Excel to enable the operation of workbook macro codes. Resetting these options assures the operation of our method materials without jeopardizing the built-in security features of MS Office.
