Process and theory Flashcards
What are the steps in a system lifecycle
Concept
Design
Test
Manufacture
Deployment
Operations
Mid-life review/update
Operations
Disposal
Often overlap, not linear
What are gates
Interfaces between each step of the lifecycle in order to review the system for the programme to move to the enxt stage
What are key enabling technologies and technoloigy readiness
KETs are the technologies needed to develop the system we want to create
Technology readiness is assessing if we have the right KETs to create the system
What are the 2 types of review in the lifecycle
PDR preliminary dewisgn review (ensures requiremetns validates, meet system requiremetns with acceptable risk, verifiable)
CDR critical design review (near final design, maturity of design for full-scale manufacture)
what is a project risk matrix
Assesses risks that may be need to elimated or reduced for a system to act safely
Vertical: probability VL,L,M,H,VH
Horizontal: Impact VL,L,M,H,VH
What are the brekdowns of design data that need to be managed
Versions (mods toughout)
Vasriants (specialisations of OG)
Views (representations of same thing)
Hierachies (system decomposiotn)
Status (maturity)
What is a WBS
work breakdown strucutre
Hierachal and incremental decomposiotn of a project into work packages
Project -> delivarables>work package->activity
What is a system of systems
An integration of a fintie number of consituent systems which are indpendnent, networked together to achieve a certain higher goal
What is a category 1 Failure
A failure which measn the project cannot move onto the next step without correction
What is a category 2 failure
A failure which means the project can carry on but the issue must still be fixed during the next step
How are gates ususally managed and reviewed
In a review meeting with a panel of stakeholders
What makes up a mid-life review
New concept
more designs
more testing
new/more manufacturing
new commisioning phase
What are the gates planned around
Financial planning
project risk management
technology readiness
manufacture
logistics
What are the technology readiness levels
Basic observations
Technology conceptualised
Proof-of-concept validation
Partical-scale prototyping modelling
Partial-scale prototype validation
Full-scale prototype field demonstration
Full-scale prototype in commercial conditions
Final prototype product certifications
Final commercial product is bank financiable
How do you mitigate the risk of failing to complete a project or completing it with definiciencies
Identify the main hazards
identify the risks of the hazards
how to mitigate hazards
impact on scheduling
