The MIT Enterprise Architecture Guide (EAG) documents MIT's architectural principles and goals, the current state of MIT's enterprise architecture, and a future state architectural vision. The EAG also includes information regarding the ITAG architecture review process. Since this document serves to inform developers about available enterprise tools and services, we expect the EAG will be useful to enterprise system developers across the institute. Because this is a constantly evolving document, community feedback will drive future ITAG agendas and thus influence content in future versions. ITAG expects to update the EAG on a quarterly basis.
Intended Audience
The intended audience of the EAG includes project teams making enhancements to existing systems, project teams developing new systems, sponsors of initiative, ITAG Members, and DLC Leadership. Each group can benefit in a different way from the EAG as detailed below.
Project Teams: Project teams can use the EAG to gain an understanding of the current architectural landscape, the future vision of the enterprise architecture, and the services available to development teams. By understanding the recommended technical standards and available MIT services, project teams can re-use existing services and create applications that fit into the long term architectural vision. Teams can also leverage the information to develop new enterprise-wide services. Finally, the EAG will assist project team members in identifying whom to contact to mitigate risks in different aspects of their project.
Sponsors: Sponsors can benefit from the EAG by gaining an understanding of the technical direction of the Institute as well as the Architectural Governance Process. This knowledge can then be used to shape their decisions regarding IT investments.
ITAG: ITAG members can use the EAG to gain a common understanding of the Enterprise Architecture at MIT. Additionally, the EAG will be used during the project review process to provide a consistent representation of the context and principles of both the current and future state. Both of these items will assist ITAG in making informed architectural decisions as well as identifying gaps in the Enterprise Architecture.
DLC Leadership: DLC Leadership can use the EAG to gain a common understanding of the Enterprise Architecture at MIT, to proactively identify potential risks in projects, and to assist in identifying individuals to help mitigate those risks.
How to Use the Guide
The EAG is divided into the following sections: Introduction, Context and Principles, Current State, Key Systems Overview, Future State, Project Review Process, and Moving Forward. As a user of the EAG, you can read it in its entirety or reference a particular section that pertains to your need.
The entire guide can be downloaded as a single PDF file (about 14 M( or in separate chapters as shown below. Pages are formatted to work best in Legal Landscape orientation, 11"x14").
Key to Documents
All sections of the EAG are available in PDF format (.pdf). Certain sections are also available in PowerPoint (.ppt), Visio (.vsd), and/or Excel (.xls) formats.
