Trade Space for Systems Analysis TSSA

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

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 OPNAV N1 NAVAIR Other services Finite state models needing scenario events, task analysis and performance estimates Requirements repositories such as DOORS DoD architectural framework tools such as ProVision and System Architect UML Modleing suites such as Rational and DescribeFinite state models needing scenario events, task analysis and performance estimates Requirements repositories such as DOORS DoD architectural framework tools such as ProVision and System Architect UML Modleing suites such as Rational and Describe
