ASE Consulting Vee Model

  1. 1. VeeDevelopmentModel Adapted from Vee Model developed by Forsberg Session 1 ©2006 ASE Consulting LLC and Mooz Visualizing Project Management 1
  2. 2. Upper left side of Vee Definition and decomposition  Systems engineering management plan (SEMP)  Planning the technical development  Control document for the project Documents will be identified for the SEMP as we go through the lessons  Concept of operation  Understanding the problem space  The way the system is envisioned to work including the Operations and Maintenance  System level requirements  “What” the system is to do to address the problem space Session 1 ©2006 ASE Consulting LLC 2
  3. 3. Lower left side of the Vee Sub-system requirements (high level design)  Transition from “what” the system must do to “how” it is to be built.  Sub-system definition and project level architecture defined  Interfaces identified  Configuration Items Identified Component level – detailed design  Software/hardware detailed design  Code specifications  Hardware specifications  Configuration Items identified cont’  Make-buy decisions Detailed design is equivalent to highway 100% PS&E packageSession 1©2006 ASE Consulting LLC 3
  4. 4. Implementation (bottom of the Vee) Implementation  Hardware and software development  Systems Engineering Audit  Code walk-through  Commercial off the shelf (COTS) products implementation (databases, object request broker, graphical user interface (GUI) products)  Hardware development (Printed Circuit (PC) Board fabrication)  Software DevelopmentSession 1©2006 ASE Consulting LLC 4
  5. 5. Lower right side of the Vee Sub-system integration and testing  Sub-system integration  Legacy system integration  External interface integration  Sub-system test readiness  Sub-system test procedures Component level integration and testing  Configuration item verification testing  Module integration  CI test proceduresSession 1©2006 ASE Consulting LLC 5
  6. 6. Upper right side of the Vee System commissioning – operations and maintenance  Final crossover  “Real-world” exposure Systems level validation  Alpha testing  Beta testing  Evaluation period  Training  Limited “real-world” exposure  Fall-back to previous baseline available Systems level integration and verification  System level test procedures  User documentation  Verification testing under controlled environment Session 1 ©2006 ASE Consulting LLC 6
  7. 7. Other aspects of the Vee Relationship across the Vee  Verification and validation test plans Control gates  Formal technical reviews Traceability  Requirements to test plan (across the Vee)  System to sub-system to design (through the Vee) Baselines  System baseline  Subsystem baseline  Design baseline  Operational baselineSession 1©2006 ASE Consulting LLC 7
  8. 8. The Vee Model View, Observations Has commercial and international acceptance Used by NHI for the Systems Engineering Training Recommended for ITS Development Relationships of the Early phases of a project to the End Results are clearly illustrated – A powerful reality!
