PROFESSIONAL ENGINEEREING SERVICES (PES)
SPECIAL ITEM NUMBERS (SIN)
SIN
871-1: STRATEGIC PLANNING FOR TECHNOLOGY PROGRAMS/ ACTIVITIES
Services required under this SIN involve the definition and
interpretation of high-level organizational engineering performance
requirements such as projects, systems, missions, etc., and
the objectives and approaches to their achievement. Typical
associated tasks include, but are not limited to an analysis
of mission, program goals and objectives, requirements analysis,
organizational performance assessment, special studies and
analysis, training, privatization and outsourcing.
Example: The evaluation and preliminary definition of new
and/or improved performance goals for navigation satellites
– such as launch procedures and costs, multi-user capability,
useful service life, accuracy and resistance to natural and
man made electronic interference.
SIN
871-2: CONCEPT DEVELOPMENT AND REQUIREMENTS ANALYSIS
Services required under this SIN involve abstract or concept
studies and analysis, requirements definition, preliminary
planning, the evaluation of alternative technical approaches
and associated costs for the development or enhancement of
high level general performance specifications of a system,
project, mission or activity. Typical associated tasks include,
but are not limited to requirements analysis, cost/cost-performance
trade-off analysis, feasibility analysis, regulatory compliance
support, technology conceptual designs, training, privatization
and outsourcing.
Example: The development and analysis of the total mission
profile and life cycle of the improved satellite including
examination of performance and cost tradeoffs.
SIN 871-3:
SYSTEM DESIGN, ENGINEERING AND INTEGRATION
Services required under this SIN involve the translation
of a system (or subsystem, program, project, activity) concept
into a preliminary and detailed design (engineering plans
and specifications), performing risk identification/analysis/mitigation,
traceability, and then integrating the various components
to produce a working prototype or model of the system. Typical
associated tasks include, but are not limited to computer-aided
design, design studies and analysis, high level detailed specification
preparation, configuration management and document control,
fabrication, assembly and simulation, modeling, training,
privatization and outsourcing.
Example: The navigation satellite concept produced in the
preceding stage will be converted to a detailed engineering
design package, performance will be computer simulated and
a working model will be built for testing and design verification.
SIN 871-4:
TEST AND EVALUATION
Services required under this SIN involves the application
of various techniques demonstrating that a prototype system
(subsystem, program, project or activity) performs in accordance
with the objectives outlined in the original design. Typical
associated tasks include, but are not limited testing of a
prototype and first article(s) testing, environmental testing,
independent verification and validation, reverse engineering,
simulation and modeling (to test the feasibility of a concept),
system safety, quality assurance, physical testing of the
product or system, training, privatization and outsourcing.
Example: The navigation satellite working model will be subjected
to a series of tests which may simulate and ultimately duplicate
its operational environment.
SIN
871-5: INTEGRATED LOGISTICS SUPPORT
Services required under this SIN involves the analysis, planning
and detailed design of all engineering specific logistics
support including material goods, personnel, and operational
maintenance and repair of systems throughout their life cycles.
Typical associated tasks include, but are not limited to ergonomic/human
performance analysis, feasibility analysis, logistics planning,
requirements determination, policy standards/procedures development,
long-term reliability and maintainability, training, privatization
and outsourcing.
Example: The full range of life cycle logistics support for
the navigation satellite will be identified and designed in
this stage including training, operation and maintenance requirements,
and replacement procedures.
SIN
871-6: ACQUISITION AND LIFE CYCLE MANAGEMENT
Services required under this SIN involve all of the planning,
budgetary, contract and systems/program management functions
required to procure and/or produce, render operational and
provide life cycle support (maintenance, repair, supplies,
engineering specific logistics) to technology-based systems,
activities, subsystems, projects, etc. Typical associated
tasks include, but are not limited to operation and maintenance,
program/project management, technology transfer/insertion,
training, privatization and outsourcing.
Example: During this stage the actual manufacturing, launch,
and performance monitoring of the navigation satellite will
be assisted through project management, configuration management,
reliability analysis, engineering retrofit improvements and
similar functions.
