Summary & Impact

ACME News Testbed

GIT Aspects Exploiting DoDAF Support in UPDM/SysML

Explore ways to make DoDAF more useful during development & 

usage of software‐intensive IT systems

Overcome current approach: 

Burdensome after‐the‐fact documentation generation

Developed new concepts and prototypes as needed (e.g., OPNET 

interface) and new models for ACME News testbed

Leveraged examples by vendors/others where feasible; adapted, 

extended, and improved them for RT24 purposes

— Provided high value to illustrate RT24 concepts 

in a wider variety of sponsor‐relevant contexts

— Ex. Compare below original vs. RT24‐enhanced models for 

OV‐4 organizational structure/FTEs

Successfully demonstrated UPDM/SysML‐enabled M&S for 

IT/network/software domain

— Diverse examples in RT24 ACME News Testbed

—OPNET, GSM, FTE calculator, deadline timer, ..., with requirements 

margins in a UPDM/SysML‐based system model context

—M&S‐intensive examples from related work

Provides strong evidence that this approach can likely fulfill 

sponsor needs per RT24 objectives

Impact:

Sponsor took SysML training in 2012 & is planning a pilot project

Greatly enhanced integration of M&S and DoDAF

for software/IT‐intensive systems

Recognize that UPDM enables “model‐based DoDAF”

Recognize that UPDM Level 1 (L1) includes SysML

Leverage SysML‐enabled modeling & simulation (M&S)

Apply capabilities to representative software‐intensive information 

systems problem (as proxy for sponsor)

Interface to representative M&S tools (e.g., OPNET)
