Enterprise Architecture Guide Project at MIT

CSG Presentation 9/23/04Jerry Grochow

MIT’s ITAG team sponsored a six week initiative to document the current state architecture and to begin development of a vision for future state enterprise architecture.

Documents will be on-line, refined, and continuously updated to reflect deeper understanding and changing needs of the Institute.

Scope of Enterprise Architecture:

•Business processes and products, applications and data (Process)

•Software and hardware infrastructure (Technology)

•Knowledge and expertise (People)

Current State Assessment:•Documentation review•Interviews with ITAG and

departmental technology staff

•Workshops to validate information gathered

Future State:•Workshops (1/2 day) to

cover:•Future State Context•Future State Principles•Logical Architecture

Framework•Technology Standards•Services Matrix•Project Review process

Future Phases:•Roadmap and Planning•Build-out


Audience and Value of the EA Guide (1 of 2)

Project Sponsors and Departmental Leadership

•Understand institute investments in technology

•Understand architectural governance process

•Provide technical direction to guide their investments

•Provide a way to assess architectural risks on projects

IT Architecture Group

•Common understanding of architecture

•Frames architectural review process for projects

•Inform gaps in the architecture and where we need to evolve

ArchitecturalPrinciples


Future State Context

• SAP will continue to be the primary ERP system

• The MIT Data Warehouse will be the central repository for

administrative data that is of interest to more than one DLC.

• The MIT community will continue to be global, 24x7 and

evolving

• There will be increased integration between MIT and other

universities

• The MIT environment is heterogeneous

• The MIT network will evolve to support needs of the enterprise

•We may have many research networks

•We will have an IPv6 network and we will need differentiated

services to better support user needs


Architectural Principles

• Security: applications should ensure data and access

security

• Ownership: clear and explicit ownership of enterprise data

• Leverage assets: leverage existing services and capabilities

• Accessibility: be aware of to needs of all users (location &

disabilities)

• Real-time: Minimize latency of data updates

• Standards: promote consistency using standards
