Overview of LMI—History

Founded in 1961 by Secretary McNamara under the Kennedy administration

“…to bring the best minds to bear on solving our government’s most complex management problems”

P A G E 4

Background/History —Continued

• LMI is an independent not-for-profit government consulting firm– Located in McLean, VA

• LMI has substantial experience assisting federal agencies with IT planning and implementation, including EA and IA.

P A G E 5

Background/History —Continued

• Dr. Didier Perdu and Dr. Roxanne Everetts

• LMI Research Fellows– Members of the EA and IA communities of

practice

• Dr. Perdu is the EA Practice Technical Advisor; over 20 years experience with EA

• Dr. Everetts leads the IA Practice, over 28 years experience in IT, last 15 in IA

P A G E 6

Initial Problem

• LMI was asked to developed an IA EA integration implementation plan– in response to requirements from GAO EAMMF to

capture security aspects in EA

• Conducted initial research to establish state of the practice and identify industry best practice for integration approach

P A G E 7

Findings

• Over-estimated maturity of the practice

• IA requirements are not included in EA models and artifacts

• IA has only been routinely integrated into Design Phase of the System Development Life Cycle (SDLC)

• Bottom line:

There is limited integration between EA and IA

P A G E 8

Why integrate EA and IA

• EA can be used to express IA throughout SDLC

• EA provides enterprise-wide coordination and integration of processes, information, and technology

• EA enables multi-layered analysis of managerial, technical and operational elements

• EA can enable organizations to meet the challenge of ensuring the optimal allocation of resources while providing the highest level of security

P A G E 9

Call to Action

• Based on findings, LMI decided that its EA approach, LEAP should be modified to integrate IA– In response to increasing requests– To best serve our government clients– To align our practice with emerging industry

standards and best practices

P A G E 10

What is LEAP?• LMI Enterprise Architecture Practice (LEAP) is the approach

used by LMI since 2000 to help federal agencies develop and implement Enterprise Architecture

• LEAP perspective is that EA is more than a set of products required to achieve compliance

LMI EA/IA Integration Methodology

• Focus of IR&D project to integrate IA into EA program

• Formed team of EA and IA specialists

• Reviewed existing EA document

• Reviewed IA controls

• Mapped NIST Security controls to EA process layers

• Identified EA products/artifacts to address controls

P A G E 12

Challenges Encountered

• No common taxonomy

• Unsure of impact of IA controls on EA artifacts

• Gap between EA process oriented focus and IA system/technology focused approaches

• Lack of Industry Best Practices for integration approach

P A G E 13

Solutions Developed

• Extend BPMN to cover process areas where security controls apply– Bridge gap between process focus vs system

focus

• For each IA control, identify changes to related EA artifacts to address security

Solutions Developed —Continued

• Initiate EA and IA staff orientation sessions– To develop common understanding and taxonomy

• Transform research into best practices– Reach out to both the EA and IA communities– Participate in the public discussion– Share our experience with the community

P A G E 16

Next Steps

• Normalize LEAP with Federal Segment Architecture Methodology (FSAM)

• Continue to monitor emerging industry standards and best practices

• Continue research and development activities
