Terminoglogy

Question 1

Definition: System

Answer 1

A system is a set of entities and their relationship (they interact or are interrelated), whose functionality is greater than the sum of the individual entities.

Question 2

Definition: Entities

Answer 2

Parts, modules, routines, assemblies, pieces that make up the whole

Question 3

Definition: product

Answer 3

A product is something that is, or has the potential to be, exchanged. A product is not a system. Example rice is a product not a system. A solar system is not a product.

Question 4

Definition: architecture

Answer 4

An abstract description of the entities of a system and the relationship between those entities

Question 5

Definition: emergence

Answer 5

Emergence refers to what appears, materializes, or. Surfaces when a system operates

Question 6

Definition: function

Answer 6

What the system does. It’s actions, outcomes, or outputs. Consists of a process and an operand. Ex. Cars transport people.

Question 7

Definition: performance

Answer 7

Performance is how well a system operates or executes its function. Ex. How quickly can a car transport its people.

Question 8

Definition: “ilitities”

Answer 8

Emergence valued that emerge over the lifecycle of the system. Reliability, maintainability, operability, safety, and robustness.

Question 9

Definition: emergency

Answer 9

Unanticipated and undesirable emergence

Question 10

Definition: value

Answer 10

Benefit (worth, importance’s, utility) at cost.

Question 11

Definition: form

Answer 11

What the system is. Physical or informational embodiment that exists or has the potential to exist. Form has shape, configuration, arrangement, or layout.

Question 12

Definition: process

Answer 12

Process is the part of the function that is pure action or transformation. Transformation applied to one or more objects. Oval in the OPM

Question 13

Definition: operand

Answer 13

The operand is the thing whose state is changed by that process. Rectangle in OPM

Question 14

Decomposition

Answer 14

Breaking a system into smaller pieces of form

Question 15

Aggregation

Answer 15

Collecting pieces into the form of a system. Opposite of decomposition

Question 16

Distinct elements/entities

Answer 16

Discrete entities brought together and defined as a system. Fleet of ships, forest of trees, library of books

Question 17

Modular elements/entities

Answer 17

Modules are relatively independent. Lots of internal relationships. Relationships between modules exist but less.

Question 18

Integral systems

Answer 18

Cannot be easily divided with their function intact. Steering mechanism (tires, wheels, suspension, steering gears, steering column) which is part of other systems like ride quality and drive.

Question 19

Context

Answer 19

Surrounds the system. Entities that are just on the outside of the system but are relevant to it

Question 20

Formal relationships aka structure

Answer 20

Is a set of formal relations among the entities of form of a system. Shows where the elements of form are located and how they’re connected.

Question 21

formal structural relationship

Answer 21

relationships that are strictly descriptions between elements of form. NOT relationships that are descriptions of functional interactions between objects of form while operating

Question 22

spatial/topological

Answer 22

a type of way to describe a formal structural relationship where you reference the relative spatial location or topology (how they’re arranged) contained, surrounded by, encompasses, encircles, overlaps, shares part of, adjacent to, touches, separated from, near, far

Question 23

connectivity

Answer 23

a type of way to describe a formal structural relationship where you reference to assembling process (bonded to, welded to, coldered to, glued to, bolted to, pressed against, inserted, is compiled with,

Question 24

Object Process Diagram (OPD)

Answer 24

Rectangles with arrows describing its relation

Question 25

Design System Matrix

Answer 25

N x N matrix where each object is a row/column entry

Question 26

product/system boundary

Answer 26

stuff in your system. What you’re responsible for.

Question 27

Whole product system

Answer 27

some stuff outside the system to help deliver the value. You don’t make it. What the customer considers what you’re accountable for.

Question 28

Use Context

Answer 28

Includes system, whole product system, and other stuff. It doesn’t not interface with the objects. Provides the context. Not necessary for it to deliver the value. Helps you figured out what’s important. (you do the fridge, but you know fridges are usually in the kitchen which would have a microwave, stove, etc.)

Question 29

Value

Answer 29

benefit at cost

Question 30

benefit

Answer 30

driven by functional externally delivered across the interface

Question 31

cost

Answer 31

driven by the design of the form
