OBASHI® is a breakthrough in Information Technology thinking that will enable you to clearly see how your business actually works facilitating better decisions as a result.

OBASHI allows you to create a visual map that shows:

  • how your business works
  • the assets that make it work
  • the inter-dependencies between those assets
  • a clear pathway for refining company processes and procedures.

With OBASHI you can design, monitor and optimize your business better; in a way which is easy to understand and, more importantly, easy to communicate across the rest of the business.

Whether your challenge is reducing costs, driving competitive advantage or both; you need to think OBASHI.

The OBASHI methodology is sequential and consists of 6 layers:

  • Ownership
  • Business Process
  • Application
  • System
  • Hardware
  • Infrastructure

These layers are mapped out in a Business and IT diagram (B&IT) which provides the framework to store this information usefully.

The OBASHI B&IT diagram is a universally useful tool because it helps simplify business complexity in a way which everyone can see and understand. For the first time you will actually be able to see how activities, processes and the supporting technical infrastructure are linked to deliver the required business outputs. If you can see and understand the challenges that your business face, then you are better placed to make the right decisions in order to help make your business better.
