ba-alignmentBusiness/IT Alignment

This offers a core reference model for transforming IT solution delivery through Business Architecture, encompassing Business/IT Alignment, an Application Architecture Roadmap design review process that unifies cross-department teams and exposes duplicated functionality for consolidation.

Most notably it explicitly describes how Business Architecture bridges the gap between Business and IT, formally establishing governance links between the goals of strategy and the execution of IT, and also how to then implement this linkage across Enterprise Architecture.

  • Slide 14 describes the core design process, a process of 'front to back' overlaying of the Logical model across the Physical one.
  • Slide 13 shows how this produces a Features List, for example T1 - A Trade Store Abstraction Layer.
  • App / Data Centre Consolidation - This is part of a simultaneous process of identifying duplicated processes and systems, and eliminating these as part of the migration, enabled by a disposition decision tree.

This includes the required organizational Design Governance models - Credit Suisse explain how they defined one that supports the process of planning legacy migrations through a 'front to back' architecture design process that maps out the dynamics between business processes and the apps that ultimately run them.

eBCM - Data Centre and Application Consolidation

Credit Suisse define a complete framework ideal for scenarios such as Data Centre and Application Consolidation.

Their ‘eBCM’, offering a core reference model for transforming IT solution delivery through Business Architecture, built around a Application Roadmap Architecture design review process that unifies cross-department teams and exposes duplicated functionality for consolidation.

Credit Suisse defines a Cloud Solution Design review process including a including a core Application Architecture Roadmap, an EA artifact produced through a logical to physical overlay process, that exposes duplicated process and application functionality that could be consolidated as part of the migration, eliminating 'Regretted Spending'.

Application Architecture Roadmap

This offers a core reference model for transforming IT solution delivery through Business Architecture, encompassing Business/IT Alignment, an Application Roadmap Architecture design review process that unifies cross-department teams and exposes duplicated functionality for consolidation.

The image slideshow shows slides 9,10 and 14 where they show how they define the component parts of the Roadmap.

Developing an Application Architecture Roadmap is a central backbone to planning your Cloud Migration.

Business Architecture best practices are the key to this, and as documented in this Credit Suisse case study they describe specifically how it can be used as a framework to plan these types of legacy to Cloud migrations.
