Why a reference architecture? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Example from AstraZeneca ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Outcome of using RA at AZ How much time did we gain, in terms of reduced architectural and technical re-factoring (%)? How much time did we gain, by reducing the time spent discussing J2EE design issues (%)? How much time did we gain, by cutting development time (%)?

Outcome of using RA at AZ 5 times the investment in a RA was harvested within a single project.

None-technical facts ,[object Object],[object Object],[object Object]

What is it - Rational? “ A Reference Architecture is, in essence, a predefined architectural pattern, or set of patterns, possibly partially or completely instantiated, designed and proven for use in particular business and technical contexts, together with supporting artifacts to enable their use. Often, these artifacts are harvested from previous projects”

What is it - OMG? “ The principles and the means to most effectively achieve a design vision”

What is it - in practice? ,[object Object],[object Object],[object Object],[object Object]

How does it look - Subsystems? ,[object Object]

How does it look - J2EE modules? ,[object Object],Application Component WEB module Application Component EJB module Business Component EJB module * * *

How does it look - Layers? ,[object Object],The project-, source and deploy directories share the same structure. This structure is a synthesis of the ref. architecture and the logical layers. Business Layer Transaction Layer Integration Layer (from Business Component) Workflow Layer Presentation Layer Common BusinessSystem Component * * Application Component BusinessComponent

How does it look - Naming standard? ,[object Object],BusinessSystem Component * * Application Component BusinessComponent

Three most important “features”

How is it used - Questionnaire ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],“ What are the three most significant advantages achieved by using the reference architecture and supporting tools?”
