Continuity
• Improved tropical cyclone forecasting will result in an increased ability to
protect property and to enable evacuation of individuals residing in the path
of the storm, while also reducing losses to the recreational boating
industry.
• Enhanced aviation forecasting results in decreased commercial aviation
delays and repair costs to aircraft due to volcanic ash.
• More accurate temperature forecasting contributes to improved energy
demand expectations and savings in the electricity and natural gas sectors.
• Enhanced forecasts will lead to more efficient irrigation of crops, resulting
in water and energy savings.

10. Partnership born from Reality
• The unique GOES-R partnership is a recognition of two basic
realities:
– GOES-R is the largest acquisition ($7.672B) ever undertaken at the
Department of Commerce. NOAA provides 100% of the funding
• NOAA has considerable experience operating weather satellite systems, and
• NOAA has extensive experience developing user products from satellite
data, yet
• NOAA has no experience overseeing a system of this size and complexity
– NASA has the expertise and experience to procure the satellite
systems, with time-tested processes that have proven successful
• GOES-R’s unique structure provides NOAA with greater
management responsibility and oversight while leveraging NASA’s
experience procuring satellite systems
This briefing describes the unique GOES-R partnership between NOAA
and NASA and identifies challenges the dual agency management
system has created and how we are dealing with them -
combining apples and oranges to make juice!

17. Overarching Communications
• PSE Lead and Deputy are members of the Senior Management Team which
directly reports to the System Program Director (SPD)
• Program System Engineering (PSE) Lead is coordinating and chairing
coordination and planning meetings with the systems engineering team
– Weekly PSE team meeting
– Weekly Program/Project SE coordination meeting
– Monthly PSE Risk Board
– Monthly Program risk board
– Weekly Program Engineering Change Review Board (ECRB)
• Systems engineering team members also participate in the following project
meetings:
– Flight and Ground Project ECRBs
– Project Risk Management Boards
– Flight Instrument Design reviews and technical meetings
– Ground system design and peer reviews
– Weekly staff meetings, systems engineering meetings, steering group
meetings
17

18. Program Standard Processes
• All procured systems:
– Will provide traceability of Requirements Verification via DOORS tool in
DOORS database
– Verification matrices to be provided by vendor, approved by Projects and
Program
– Contractors’ proposed test plans to be based on Verification Matrices and
Government-specified schedules
– Flight/Ground Projects will oversee factory and site testing,
– including intra-segment interfaces
– PSE will maintain visibility in all system activities and interfaces
• Program-wide consistent Configuration Management (CM) Plans and
coordinated change review processes
• Program-wide Risk Management database with multiple levels for subsystems,
projects and program
• Program-wide Schedule management system will be developed and maintained
• Working groups for Program-wide efforts
– Will include PSE, Flight and Ground Projects, and
Contractors as required
18

19. Tailoring of SE to GOES-R
The Classic top-down System Engineering Process must be tailored to
address the GOES-R Program
• Because of the Long Lead time required for development of a GEO
Imager, the ABI instrument and other instruments’ designs were
started well in advance of the spacecraft procurement. Some
“bottom up” flow of requirements and capabilities must be carefully
woven into the overall system to minimize cost, schedule, and
performance impacts.
• Review and approval processes must accurately reflect
NOAA/NASA partnership strengths and responsibilities
• Continuity with current GOES operations and data must remain as
a top priority
• Decision to acquire two prime contractors, one for Ground and one
for Space brings forth some new risk considerations like
coordination of interfaces, synchronization of schedules, etc.
19

20. Critical Inter-Project
Dependencies being
monitored by PSE
• Delivery of the Level 1b processing algorithms from the five
instrument vendors for subsequent delivery to the Ground Project
contractor for operational implementation.
• Delivery of telemetry and command design information from the
satellite contractor to the ground contractor to support the design of
that portion of the ground segment
• Delivery of satellite simulators (from the spacecraft contractor) for
use by the ground segment contractor for development and testing.
• Readiness of the telemetry and command portion of the ground
segment sufficient to support compatibility testing during the S/C
Thermal-vacuum testing.
• Availability of the satellite to conduct end-to-end tests with the
ground segment.

21

22. Challenge #1 –
Defining the Partnership
Defining the GOES-R partnership explicitly required defining the
responsibilities of each agency, the program office and each project
NASA and NOAA have fundamentally different cultures:
• NASA focuses more on proven processes while NOAA focuses more
on agility/flexibility to support users
• NASA focuses more on flight hardware with high reliability for first
time success while NOAA focuses more on evolving
science/operational product applications that can change over time.
• The different cultures lead to
– different sets of priorities
– different concepts of what represent success.
• Having the difference in cultures primarily located across the
important boundary that is Flight and Ground enhances the
challenge.
Required significant discussion, review, and revision until all parties
were in agreement
22

23. MOU and MCP Define Agency
Roles and Responsibilities
• Memorandum of Understanding (MOU) established
GOES-R as a NOAA led program with two projects–
signed June 15, 2007
– Spacecraft: NASA contract
– Ground Segment: NOAA Contract
– Recognized the strengths of each agency
• Management Control Plan written to implement MOU
– Requirements mirror NPR 7120 as much as possible
– Deviations from NPR 7120 when similar NOAA process is being
used instead
• i.e. NOAA independent cost estimating processes being
utilized
23

24. On a Dual Agency Program,
Documents Require Unique
Approvals
• Memorandum of Understanding
(MOU) between NOAA and NASA
created GOES-R as a co-located
Program Office with Flight and
Ground Segment Projects.
Approved by:
– NOAA Deputy Under Secretary
– NASA Associate Administrator
• Management Control Plan (MCP)
written to implement MOU.
Approved by:
– NESDIS Director
– GSFC Director
24

25. Challenge #2 –
The Review Process
The GOES-R Review Process is defined in the System
Review Plan, coordinated with both agencies
– based on NASA standards and processes
– NASA and NOAA independent experts on review
panels with joint chairs
– NASA and NOAA approvals for program milestones
PSE worked with Goddard’s Systems Review Office to develop a
plan that met NASA requirements but tailored to GOES-R

30. Challenge #4 –
Approval to Enter Acquisition and
Operations (A&O) Phase
Approval to Enter A&O Phase, which in our case included
permission to spend our money on our development
contracts, was a challenge due to:
• Many layers of review and approval
• Independent Review Team recommendations that drove
us to a conservative 80 percent budget solution
• Challenges reconciling NASA and NOAA independent
cost estimates
GOES-R received formal approval from the Department of Commerce to
enter the A&O Phase in December, 2007
30

31. Challenge #5–
Configuration Control
Dual-agency configuration control is a challenge on GOES-
R, particularly for the documents “owned” by NOAA, i.e.
the Level 1 Requirements and Management Control
Plan:
• All elements of the Program as well as both Agencies
need to be a part of the review cycle
• Must carefully control requirements yet still allow for
necessary changes
Required significant discussion, review, and revision until all parties
were in agreement – still being refined

33. Challenge #6 –
Risk Management
The GOES-R Risk Management Process follows NASA and DOD requirements
as closely as possible while maintaining consistency with other NOAA
programs (NPOESS, etc)
• Characteristics of Integrated Risk Approach
– Multi-layer approach for risk management that allows cognizant projects,
segment organizations, contractors, teams, groups, and organizations to retain
authority and control over risks for their areas of responsibility while supporting
existing management and decision making processes.
– Program risks address technical, cost, and schedule impacts related to the:
• Successful design, development, fabrication/manufacture, integration, tests,
deployment and operations of the GOES-R system;
• Performance and reliability of the GOES-R Series End-to-End System.
• Activities and resources including staff, contractors, and facilities, at NOAA
and NASA, at other government agencies, developer organizations
– Comprehensive approach allows early identification of potential risks
Risk Management Plan baselined. Required discussion with other NOAA
programs to ensure consistency

35. Challenge #7 –
Schedule Management
Having 2 projects each with multiple contractors adds
complexity to the problem of developing and maintaining
an integrated Program Schedule
– Project Schedulers are integrating at Project Level
– Program scheduler hired to combine project schedules at
Program Level – at this point a manual effort
– PSE responsible for analyzing schedules for technical
inconsistencies and working out conflicts
– Program Schedule Management Plan being written
Developing an initial Program Schedule required significant discussion,
review, and revision until all parties were in agreement. GOES-R is still
developing its full integrated Program Schedule

37. Challenge #8 –
Requirements Management
Defining GOES-R requirements was a dual-agency challenge: GOES-R
Requirements have come from both agencies
– Stakeholder requirements from NOAA
• Science Product requirements
• Operations requirements
• User interface requirements
• Continuity requirements
– Process requirements from NASA
• Spacecraft and Instrument design, development, integration
and test requirements
• Requirements from NOAA and NASA combined into single set of
requirements documents
ALL program elements using DOORS are part of a unified, multi-level
requirements database.

39. Challenge #9 –
System Integration
Defining the responsibilities and full process for system integration is a
challenge in a dual-agency program:
• PSE is responsible for the overall integration of the GOES-R System
• The Flight Project is responsible for the integration of the
instruments, spacecraft, launch vehicle, and operation of the
spacecraft
• The Ground Project is responsible for the complete integration of the
ground system into operations, and all interfaces to the users
• Integration is a build-up process, from subsystems to systems to
projects and then to program
Defining System Integration is an on-going PSE challenge. Previous
GOES process is the starting point, modified for unique GOES-R
structure.
39

40. Challenge #10 –
System Acceptance
Defining the full process for System Acceptance is a unique
challenge:
• Contractors hand over to their projects for Government
Acceptance
• Program is integrated then Program Director hands
integrated system over to NOAA/Operations.
• Handover will be in stages – product validation will
require longer time than spacecraft operations
Defining System Acceptance is an ongoing PSE challenge.
40

41. Summary
• The Geostationary Observational Environment Satellites
(GOES)-R is a $7 billion system of satellites, sensors
and data processing and distribution systems being
developed by a unique dual-agency partnership.
• This brief discussed how the partnership was formed,
the unique challenges it faces and how Program
Systems Engineering Group is the glue that integrates
the Program as a whole.
