Author:

Paul Wallis & Fergus Cloughley

Audience:

Anyone in the business including IT

Coverage:

OBASHI™ is a methodology that helps you get a clearer picture of how your business works. It allows you to create a visual map of the business that shows how the business works, the assets that make it work (physical and logical) and the interdependencies between the assets.

OBASHI is designed around four key concepts summarised by the statement: ‘with clarity and vision you can develop and improve’. The book comprises four sections. Section A provides an introduction and executive briefing. Section B provides a more detailed understanding and furnishes the reader with a working knowledge of how to use the methodology. Section C is for professionals who want to create, analyse and simulate an OBASHI business model. It describes the practical steps required to begin an OBASHI project and the technical aspects of the Business and IT (B&IT) diagram layout, modelling and analysis techniques. Section D contains appendices that cover: how OBASHI can work with other best practices including P3O, MSP, Prince2, and ITIL. It also contains case studies and template documentation to help the practitioner build the OBASHI model.

Level:

Beginner – advanced.

Karen’s Comment:

What I like about OBASHI is in its simplicity yet depth. The methodology creates B&IT diagrams like the one shown below. B&ITs provide a framework to document and model how people, processes and technology interact to make a business work. A B&IT diagram has six layers.

The layers arranged from top to bottom of the diagram are called Ownership, Business Process, Application, System, Hardware and Infrastructure. Their first letters spell the name OBASHI. Elements are placed in the layers that represent the people, process, and technology in a business. They can be related via their location in the diagram or by connectors and dependencies.

When I started to read the book I wondered what the relationship with ITIL Service Asset & Configuration Management was. OBASHI is a methodology, in ITIL terms, for creating Configuration Models. Whereas ITIL is very IT focussed, OBASHI is business focussed and enables the business conversation. OBASHI provides the big picture.

This book provides everything to need to start using the methodology including all the templates you will need. It is comprehensive and in-depth, yet easy to read and understand.

I highly recommend this book to anyone wanting to capture and communicate in a clear and understandable form (at all levels of an organisation), the way in which the organisation works and support decision-making.

You can read more about OBASHI at the ITSM Review where Claire Agutter has published two articles on the methodology or visit the OBASHI website.
