What is quality?
Meeting customer requirements
What is reliability?
To meet customer requirements consistently over a time period
What model is used to measure customer satisfaction?
The Kano Model
3 levels of customer requirement
basic, normal and latent (extra)
What are the total quality related costs? Include good and poor quality costs
Good:
Appraisal costs
Prevention costs
Poor:
Internal and External failure costs
Describe the flow chart symbols for start/end, input/output, process and decision.
start/end = oval
input/output = parallelogram
process = rectangle
decision = diamond
What are the 3 project management strategies
Prince 2: Controlled project management that leaves nothing to chance.
Waterfall - planning projects fully, then executing through phases. No changes after requirements set.
Agile - Collaborating to iteratively deliver whatever works as you go along.
Scrum (agile) - Agile cycles of daily sprints, or monthly sprints. Categorize priorities each sprint. Difficult to keep clients up to date. (IT)
Kanban (agile) - Improving speed and quality by increasing visibility of work in progress, and limiting multitasking. Work in weekly sprints. (manufacturing)
What are the two tools for cause analysis in quality?
ishikawa (fishbone)
paerto (80 - 20_
What are the 3 categories of components to an ishikawa diagram.
M’s:

P’s:

What is the poke yoka?
Prediction or recognise defect is about to occur and provide warning
Design out potential errors
What does pareto analysis dictate?
80% of problems caused by 20% of problems
What are the 4 houses of quality?
- technical requirements
- component charecterisation
- process operation
- quality control plan
Explain continuous quality management.
A corrective loop that is constantly improving quality.
What is TQM?
Total quality management:
- Covers every level of the business
- Covers the entire length of the production line
- Correct the first time
Whats the deming cycle
Plan > do > check > act
What is risk based thinking?
ISO9001
determines factors that could cause its processes and quality management system to deviate from the planned results.
Put preventative controls in place to minimise negative affects
What is the definition of risk and how is it calculated?
exposure to harm, danger or loss to someone or something valued, with an indication of the level of harm caused.
Risk = Probability of event occurring * level of harm if it occurs
Quantative vs Qualititive
quantitive - more in depth, asign numbers to risk
Qualititve - less in depth but would be carried out first. Only assign low medium and high to risk.
‘What if’ analysis
Changing risk values to assess impact of these changes
human reliability analysis
determine human input to risk and reaction to failure
what are the 5 stages of risk management?
- identify
- analyse
- prioritise
- determine action
- monitor
fault tree analysis
identify problems before they occur
event tree analysis
After an accident has occurred, work backwards through events to determine event causing accident
Redundancy?
fail safe or backup
