OOSEM is and MBSE method used to _________ and __________ systems.
specify, model
What is a N2 Diagram
systematic approach to analyze interfaces
In MBSE, the ______________ is the primary artifact of the SE process
System Model
What is "waste" defined in Product Development?
the work element that adds no value to the product or service in the eyes of the customer
What is the purpose of a system model?
to represent a system and its environment
What is the difference between a "model" and a "simulation"
) a simulation is the implementation of a model (or models) in a specific environment that allows the simulations execute over time
What is the average percentage of wasted charge time in government programs?
88%
Identify the two typical interface analysis methods/tools in the list below
B) N2 Diagram D) Design Structure Matrix
Identify the two types of prototyping commonly used
B) rapid C) traditional
What does FFBD stand for?
Functional Flow Block Diagram
____________ requirements should be arranged in their logical sequence, so that lower level ______________ requirements are recognized as part of higher level requirements..._______________ should be successively established from highest to lowest level for each _______________ and interface
Functional, Functional, Performance, Functional
What is an IPDT?
Integrated Product Development Team
The formation of what group reduces risks inherent in concurrent product development?
Integrated Product Teams.
OOSEM
Object Oriented Systems Engineering
Early in the SE life cycle, what is the objective of modelling and simulation?
Obtain information about the system before significant resources are committed to its design.
Which of these are types of waste in Product Development?
Overprocessing Unnecessary movement Overproduction Transportation Inventory Defects Waste of human potential
Identify the six Lean Principles
Specify Value Identify the Value Stream Generate Flow Pull Principle Pursue Perfection Respect people
The _________ from the ______ has emerged as an important modeling language for systems
SysML, OMG
Where does Lean development and the broader methodology of lean thinking have it's roots in?
Toyota's "just in time"
What is a function?
a characteristic task, action, or activity that must be performed to achieve a desired outcome.
What is the definition of a "model"?
an abstraction or representation of a system, entity phenomenon or process of interest
prototype can facilitate
both the awareness and understanding of user needs and stakeholder requirements.
IPD recognizes the need to consider all elements of the product life cycle from
concept through disposal, starting at the beginning of the life cycle.
The basic principle of IPDT is to get all ___________ involved at the beginning of product development to ensure that needs and _________ are completely understood for the full life cycle of the product.
disciplines, requirements
Models represent the essential characteristics of the SOI, the _________ in which the system operates and the __________ with enabling and interfacing systems and operators.
environment, interactions
What is the general approach for forming an IPDT?
forming a cross-functional team for all products and services
What is "value" defined as in SE?
mission assurance and satisfying the customer and all other stakeholders
OOSEM integrates object oriented concepts with
model-based and traditional SE methods to help architect flexible and extensible systems that accommodate evolving technologies and changing requirements.
Another important aspect of modeling and simulation management is the
ongoing validation
Models and simulations can be used to identify critical system parameters and asses ____________ risks of any uncertainty that lies in those parameters.
risk
The model's depth indicates the coverage from the _________ context down to the system __________.
system, element
Where are Interfaces identified?
the architecture definition process
If needed, where is any further refinement and detail of the interface definition provided?
the design definition process
MBSE is
the formalized application of modeling to support system requirements, design, analysis, VERIFICATION and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.
