Services in Business

Services we provide• To customers• To other stakeholders e.g.

partners, suppliers, government• To other business units

Services we consume• From service providers• From other stakeholders• From other business units

Typically supported by services at other levels e.g. Process, Application, Information, Technical

Applications

• No longer monolithic, isolated

Sometimes not oursSometimes distributedHeterogeneous technologiesNeed to think of as a Bundle of functions Exposed as services Malleable, like Amoeba

Logical Applications vs Physical Components•Components can be part of more than one application•Components can be replaced without impacting overall service

Interfaces

• Where things fit together

• Plug and Play• Replace

o Technologyo Implementation

without impact

• Require standards• Loose coupling

Planning vs Realisation

Requirements expressed at logical level

• Independent of o Implementationo Technologyo Detail

Realisation expressed at physical level

• Technology dependent

Mapping essential between perspectives

Meta Model

Defines the necessary concepts, relationships and properties

Covers domains of business, process, application, information, technology

Distinguishes between logical and physical

Maps domains & layers

Maps to notation to represent / model

Support of services for Products

Must be able to categorise by e.g.

Delivery mechanism (channel)

Etc.

Enrichment

To deliver good services reliably, we need

Extra concepts for IntentBenchmarks, Goals and Objectives

Mapping to responsibility and ownership

Business Unit, Roles

Monitoring of cross cutting concerns e.g.

Risk, Cost, Quality

Computation and Analysis facilities built in add huge value
