Background: Problem Statement

Net-Centric Eco-System

  • Net-centric enterprises engage semi-autonomous business units, each with its own goals and methods for characterizing “requirements”

  • These units often need to collaborate using common IT systems, involving integration or merging

  • Missions and unit needs evolve over time

  • Legacy systems exist and must be addressed

  • How should capabilities and requirements be managed?

How to enable?

Collaborative Interoperation / Integration / Merging

Our goal: Specify a methodological framework for requirements management, identify candidate Methods, Processes and Tools (MPTs), and use case studies to aid in solution development and value articulation

Solution Approach: Methodological Framework

Problem Framework

  • Decompose high-level capabilities into software requirements, then into architectures

  • Provide support for multiple stakeholders involved in net-centric integration (conflicting needs, compartmentalized information)

  • Provide support for traceability

  • Use a spiral decision process to incrementally involve lower levels of detail and incorporate evolution of needs

Candidate Netcentric SoS Capabilities


Candidate Netcentric SoS Requirements


Candidate Netcentric SoS Architecture

Solution Details: MPTs, Case Studies and Validation

MPT Mapping

To Problems

  • Methods, Processes and Tools (generic systems/software)

  • Win-Win – MPT for negotiating and resolving multi-stakeholder conflicts regarding IT requirements

  • System-of-systems toolkit – MPTs for going from capabilities to requirements

  • Adopt-and-Go – MPT for selecting one system from among multiple

  • CBSP – MPT for deriving architecture design decisions from IT requirements

  • COSYSMO for SoS – MPT for estimating cost of software-intensive system-of-systems given size factors and cost parameters

Next step: Use case studies to adapt MPTs and integrated solution to net-centric domain

  • Regional area crisis response

  • Mergers (HP-Compaq)

  • Back-office IT integration (ISP)

  • Health IT

  • Case Study Analogy Approach

  • ∙ Apply the methodology/MPTs:

    • Identify issues/challenges

    • Determine MPT adaptations

    • Evaluate methodology

  • ∙ Expected outputs:

    • Manual/tutorial

    • Other research problems

  • Validation Goals and Approach

  • Determine capabilities and gaps with respect to managing requirements IT integration efforts in net-centric-like environments

  • Determine extent to which our methods and tools address gaps

  • Determine specific reactions and insights

    • Enterprise systems integration

    • Health IT integration

  • Surveys and interviews

    • Developed generic instrument

  • Walk-throughs and usage



  • Methodology/MPTs

    • Specified generic solution framework

    • Indentified candidate MPTs

  • Case studies and validation

    • Case studies to adapt MPTs to net-centric domain and demonstrate solution value

    • Validation with third-party systems integrators to identify gaps and independently demonstrate solution value
