Introductio to Systems Engineering Flashcards
Define a System
The combination of elements that function together to produce the capability required to meet a need
Define a stakeholder
An individual or organisation that has a vested interest in the business and/or is affected ny or accountable for the outcome of an undertaking
What is a an SVN
Stakejp;der value network
A diagram that puts each stakeholder in a circle and connects the circles with 2 lines indicating what each stakholder is provinding for the business/project and what that stakeholder recieves in return
What is a use case
A technique for capturing, modelling and specifiying the requirements of a system.
It defines how an actor/user interacts with the system to achieve a desired outcome.
Why is a use case useful
Establishes reqiurements for the system
Outline show users with interact with the system
Can visualise system architecture
Communicate technical requiremetns to stakeholders
Risk management
When would you use «includes» or «extends»
Includes is when the factor includes another step underneath that step that is mandatory e.g. an atm reading someones card «includes» Verify its them
Extends is an optional extra that could be included e.g. taking someones food order «extends» taking wine order
Define a capability
The ability to execute a specifies course of action
Defined by a user and expressed in non-equiptment based operational terms
What are the characteristics of capabilities
Concerned with devlivering long-term outcomes rather than outputs with capability gap analysis
Enduring (upgrades rather than replacing)
How is capability acquired
Incrementally
Continous updating of subsytems
What are the 11 systems engineering functions
MOVER TRICAR
Mission objectives
concept of Operations
Validate and Verify
Environment
Requirements
Technical resource budgets
Risk mangement
Interface control
Configuration mangement and documentation
Architectureal design developement
system milestone Reviews and Reporting
What do the 11 systems engineering functions do
Map the process
What environmental factors impact a system
The area surroudning the project (physical, social….)
Current infrastructure
What is epistemic uncertainty
related to the observers understanding (reduced by gathering more information
What is aleatory uncertainty
intrinsic randomness (cannot be reduced)
What is the concept of operations
How a system is intended tow okr
How to run a system functionally
Addresses affects
Characteristics and system properties
