The Birth of a Method - Where did OUM come from?
- by user702549
It seemed fitting to start this blog entry with the OUM vision statement.
The vision for the Oracle® Unified Method (OUM) is to support the entire Enterprise IT lifecycle, including support for the successful implementation of every Oracle product.
Well, it’s that time of year again; we just finished testing and packaging OUM 5.6. It will be released for general availability to qualifying customers and partners this month. Because of this, I’ve been reflecting back on how the birth of Oracle’s Unified method - OUM came about.
As the Release Director of OUM, I’ve been honored to package every method release. No, maybe you’d say it’s not so special. Of course, anyone can use packaging software to create an .exe file. But to me, it is pretty special, because so many people work together to make each release come about. The rich content that results is what makes OUM’s history worth talking about.
To me, professionally speaking, working on OUM, well it’s been “a labor of love”. My youngest child was just 8 years old when OUM was born, and she’s now in High School! Watching her grow and change has been fascinating, if you ask her, she’s grown up hearing about OUM. My son would often walk into my home office and ask “How is OUM today, Mom?” I am one of many people that take care of OUM, and have watched the method “mature” over these last 6 years. Maybe that makes me a "Method Mom" (someone in one of my classes last year actually said this outloud) but there are so many others who collaborate and care about OUM Development.
I’ve thought about writing this blog entry for a long time just to reflect on how far the Method has come. Each release, as I prepare the OUM Contributors list, I see how many people’s experience and ideas it has taken to create this wealth of knowledge, process and task guidance as well as templates and examples. If you’re wondering how many people, just go into OUM select the resources button on the top of most pages of the method, and on that resources page click the ABOUT link.
So now back to my nostalgic moment as I finished release 5.6 packaging. I reflected back, on all the things that happened that cause OUM to become not just a dream but to actually come to fruition. Here are some key conditions that make it possible for each release of the method:
A vision to have one method instead of many methods, thereby focusing on deeper, richer content
People within Oracle’s consulting Organization willing to contribute to OUM providing Subject Matter Experts who are willing to write down and share what they know.
Oracle’s continued acquisition of software companies, the need to assimilate high quality existing materials from these companies
The need to bring together people from very different backgrounds and provide a common language to support Oracle Product implementations that often involve multiple product families
What came first, and then what was the strategy?
Initially OUM 4.0 was based on Oracle’s J2EE Custom Development Method (JCDM), it was a good “backbone” (work breakdown structure) it was Unified Process based, and had good content around UML as well as custom software development. But it needed to be extended in order to achieve the OUM Vision.
What happened after that was to take in the “best of the best”, the legacy and acquired methods were scheduled for assimilation into OUM, one release after another. We incrementally built OUM. We didn’t want to lose any of the expertise that was reflected in AIM (Oracle’s legacy Application Implementation Method), Compass (People Soft’s Application implementation method) and so many more.
When was OUM born?
OUM 4.1 published April 30, 2006. This release allowed Oracles Advanced Technology groups to begin the very first implementations of Fusion Middleware. In the early days of the Method we would prepare several releases a year. Our iterative release development cycle began and continues to be refined with each Method release. Now we typically see one major release each year.
The OUM release development cycle is not unlike many Oracle Implementation projects in that we need to gather requirements, prioritize, prepare the content, test package and then go production. Typically we develop an OUM release MoSCoW (must have, should have, could have, and won’t have) right after the prior release goes out. These are the high level requirements. We break the timeframe into increments, frequent checkpoints that help us assess the content and progress is measured through frequent checkpoints. We work as a team to prioritize what should be done in each increment. Yes, the team provides the estimates for what can be done within a particular increment. We sometimes have Method Development workshops (physically or virtually) to accelerate content development on a particular subject area, that is where the best content results. As the written content nears the final stages, it goes through edit and evaluation through peer reviews, and then moves into the release staging environment. Then content freeze and testing of the method pack take place. This iterative cycle is run using the OUM artifacts that make sense “fit for purpose”, project plans, MoSCoW lists, Test plans are just a few of the OUM work products we use on a Method Release project.
In 2007 OUM 4.3, 4.4 and 4.5 were published. With the release of 4.5 our Custom BI Method (Data Warehouse Method FastTrack) was assimilated into OUM. These early releases helped us align Oracle’s Unified method with other industry standards
Then in 2008 we made significant changes to the OUM “Backbone” to support Applications Implementation projects with that went to the OUM 5.0 release. Now things started to get really interesting. Next we had some major developments in the Envision focus area in the area of Enterprise Architecture. We acquired some really great content from the former BEA, Liquid Enterprise Method (LEM) along with some SMEs who were willing to work at bringing this content into OUM. The Service Oriented Architecture content in OUM is extensive and can help support the successful implementation of Fusion Middleware, as well as Fusion Applications.
Of course we’ve developed a wealth of OUM training materials that work also helps to improve the method content. It is one thing to write “how to”, and quite another to be able to teach people how to use the materials to improve the success of their projects. I’ve learned so much by teaching people how to use OUM.
What's next?
So here toward the end of 2012, what’s in store in OUM 5.6, well, I’m sure you won’t be surprised the answer is Cloud Computing. More details to come in the next couple of weeks!
The best part of being involved in the development of OUM is to see how many people have “adopted” OUM over these six years, Clients, Partners, and Oracle Consultants. The content just gets better with each release.
I’d love to hear your comments on how OUM has evolved, and ideas for new content you’d like to see in the upcoming releases.
