1. Trade Space for Systems Analysis (TSSA) A Tool for Promoting‘Quantitative Common Sense’in Systems Analysis and Design
Milton L. Stretton
2. Problem Statement Programs generally do not consider the human as part of the system
This is especially true early in design where decisions can
Lead to high training & manning costs
Degrade total system performance
Decrease human reliability 2
3. 3 Problem is Pervasive Mission and environmental complexities drive technology
Cost drives doing more with less people
Occurs in most government and industry procurements
4. 4 What is done today? Engineering activities occur in Integrated Product Teams (IPTs)
Representation from various disciplines is highly variable
Different IPTs use different tools and techniques that rarely work together
IPT inter-communication is word of mouth or “sneakering” files
Through Herculean efforts projects actually “succeed” – read “are completed”
5. 5 TSSA Requirements Need to apply quantitative common sense to early trades in a structured, repeatable process
Integrate previously separate engineering activities
Examine trades (cost, schedule, risk, and tailored parameters of interest) in a distributed, common framework
Desired interoperation between two important views
Operational (scenario and activities)
System (functional and technology/human resources)
6. Sonalysts Solution - TSSA Web-managed and launched tool for engineering teams to explore early design decisions for highly complex systems
Provides all stakeholders a quantitative means to be “heard” in system decisions
PMs, government oversight, lead engineers, integrators, scientists, human performance specialists, trainers, and others
Goals
Provide structure
Create early decision traceability
Allocate early between humans and technology to reduce future cost and risk

9. FunctionalArchitecture Evolution
13. Solution Testing
16. 16 Where are we now? Version 1.0 completed February 2007 (Phase II) TRL-6
Web-based project initialization and Java web-start client
Currently have a functional capability with limited reporting
Version 2.0 in progress through Aug 07 (Phase II Option) TRL-7
Improving the reporting
Will have a extended functional capability tested in a real acquisition environment
Future Phase III plan – Moving toward an enterprise solution
Common object reuse across programs with improved collaboration
Common API between input and output programs
17. Transition Pathway Used in support of the LCS program and potentially the SPS program
Initial strategy is to promote tool use throughfree licensing with modification & integrationwork performed by Sonalysts
Working with NAVSEA to identify Phase III requirements
Other targets
