NGT Project Approach
10
Approach to Mitigate the Risks

• Start with PES/LAS, the most mature module with
  the most thoroughly documented business rules
• Use agile methodology based on Scrum
  methodology
• Non-fixed scope project with fixed budget and
  schedule
• Rapid development with frequent review and
  validation
• Monthly sprint cycle plan, execute,
  review/validate
• Ability to adjust direction quickly based on
  discovery
• Frequent collaboration with TTF, including
  face-to-face meetings
• Weekly TTF Conference Call
• Monthly End Sprint Reviews
• Hands-on product validation at each iteration

11
Benefits of Agile Approach

• Lower risk since scope is flexible refined as
  needed
• Get business value sooner since priorities are
  continually reviewed and adjusted
• Better solution in the end because you can adjust
  to changing conditions and knowledge gained
• Lower overall cost because risks are mitigated by
  the methodology
• Higher quality due to more frequent customer
  reviews and testing

NGT Phase 1
13
Phase I Project Risks

• Building new architecture with evolving
  technology
• Redefining the user interface and user experience
• Moving business rules from GUI and middle tiers
  into a service-oriented model
• Broad reach of data and security model and
  business rule unification goals

14
NGT Phase 1 Project Goals

• Implement Trnsport proposal, letting, and award
  business functions, releasing to all licensees
  when functionally equivalent to client/server
  PES/LAS
• Develop architecture Phase 1 functions require
  forward-looking design for future phases
• Architecture
• Business rule unification
• Data model unification
• Security model unification
• User interface look-and-feel unification

15
Phase 1 Migration Assistance

• Agencies have made significant investments in
  configuring Trnsport and developing custom
  extensions to Trnsport
• Phase 1 Migration Assistance Plan
• Customization inventory and migration assessment
• Migration scope estimation
• Funded migration assistance available to PES/LAS
  licensees for a limited time after production
  release

NGT Roadmap
This schedule is tentative and is subject to
change due to factors such as funding
