Module 7 - Engineering Disciplines Flashcards
Three categories of system engineering
System
System Elements
Enabling System Elements
System
A system is an aggregation of system elements and enabling system elements that achieves a given purpose or provides a needed capability
System Elements
System elements include configuration items, subsystems, segments, components, assemblies, and parts.
Enabling System Elements
The enabling system elements provide the means for delivering a capability into service, keeping it in service, or ending its service, and may include those processes or products necessary for developing, producing, testing, deploying, and sustaining the system.
Systems Engineering
Invloves design and management of a total system that includes hardware, software, and interoperability as well as other system life cycle elements
The functions of Science and Technology
Transitions technological developments for use by oeprational forces
Demonstartes new and emerging technologies that have a direct application to military systems
Evaluates the technologies intended to be implemented into future military systems to inform aquisition decisions
Test and Evaluation
Compares system or components agaisnt requirments and specifications through testing
Results evaluated to assess progress of design, performance, and supportability
Life Cycle Logistics (LCL)
Multifunctional, technical management disicpline associated with the entire life cycle of a system.
Two principle objectives to ensure that:
- Support considerations are an integral part of the systems design requirments so that the system can be cost effectively supported
- Infrastructure elements necessary for the initial fielding and operational support of the system are identified, developed, and acquired
Production, Quality, and Manufacturing (PQM)
Goal is to ensure producibility of the system design (relative ease of manufacturing and item or system)
Standards
A document that establishes unifrom engineering or technical criteria, methods, processes, and practices
Specification
Document prepared to support acquisition that describes essential technical requirements for materiel and the criteria for determining whether those requirements are met
Two types:
- Performance specifications
- Detailed specifications
Performance specifications
Describes the function, performance, and interfaces associated with a product, but does not specify the explicit design and materials that will be used to achieve that performance.
Detailed specifications
Describes explicitly how the product solution is to be achieved.
Systems Engineering in Material Solution Analysis (MSA) Phase
Translate viable concepts (whose functionality can be traced to requirements) into designs.
Through the AoA, assessment is made of critical technologies, tech maturity, and tech risk to determine best possible system solution
Systems Engineering in Technology Maturation and Risk Reduction (TMRR) Phase
Reduce technological risk to determine and mature the appropriate set of technologies to be integrated into a full system
Reduce technological, engineering, integration, Life Cycle COst risks to facilitate a contract decision for Engineering and Manufacturing Development (EMD) phase
