OBASHI and the CMDB

In September 2010 APMG unveiled its new OBASHI Certification based on the OBASHI methodology developed in 2001 in the gas & oil industry. I won’t go into detail here, but there is at least one book available at the APMG-Business Books but apparently not on Amazon, and least of all not in Kindle format. There is also a OBASHI Explained white paper. Confession: I haven’t yet read the book.

This is just a first impression, and it was this: this is a lot like the CMDB analysis I have done several times in the past. Here is a CMDB framework which I have commonly seen used in industry.

At the top you can imagine are products that your company offers to its customers. Those products are provided by Users (of Services provided by IT), which may be individual users, departments, divisions, teams, etc. The Users use services which may be provided by other services or by applications. Applications run on servers and computers, which are connected by networks.

That sounds obvious but have found some people find it a bit abstract until they start laying out practical examples. The important thing to remember is the objects (rectangles on a diagram) are connected by arrows. In CMDB parlance, the objects are Configuration Items (CI’s) and the arrows are relationships. I typically label the diagrams.

The OBASHI framework seems to use the same concepts. When modeling a CMDB I usually allowed the customer a little more flexibility of CI Types and Relationships, depending on their requirements. OBASHI seems a little more rigid in the use of components and data flows.

At first I wondered what is the purpose of OBASHI. However, I like it after further thought. Although it describes data flows, it is easy to envision it describing other flows, such as process flows. It is an effective framework for analysis that effectively communicates complex systems. It doesn’t require the full implementation of an expensive CMDB to achieve its benefits, and the information collected will readily be reused in the implementation of a CMDB.
