Quality Flashcards
(86 cards)
1
Q
Quality is largely defined by what?
A
the degree of compliance with the customer’s request
2
Q
What is the definition of quality?
A
Latin: Qualitas = quality, characteristic, property, state
Definition in DIN EN ISO 8402:
The “set of characteristics of a unit with respect to its suitability to satisfy specified and implied requirements”.
DIN EN ISO 9000:2005 (QM standard): Degree up to which a set of inherent (i.e., intrinsic) characteristics meets requirements
This applies to products, services, concepts, drafts, software, workflows, procedures, and processes
3
Q
What is the Jidoka (自働化) principle?
A
means stopping a process whenever an anomaly occurs
That way mistakes are not passed on to the next process!
Hence problems can be solved right where they occur and quality is procuded.
It is described as “intelligent autonomation” or, translated literally, as “automation with a human element”
The principles of Jidoka can be applied, beyond systems and machines, to any process, including manual ones: resolution of customer complaints, identification of material defects, etc.
4
Q
The results of Jidoka include what two elements?
A
- Quality right from the start
2. Productivity
5
Q
What are the advantages and benefits of Q-alarm and Q-stop?
A
- Fast notification of support in case of problems of any kind
- Line Stop according to principles of first time quality when problems can not be resolved within cycle time
- Early detection of problems in combination of the 70% marking
- Possibility to identify and eliminate top problems by using systematic analysis tables coming from the Q-Alarm system
- Enhances transparency and active handling of defects
- Visualization of the status of the station/line visible for management/staff
6
Q
Andon signal should always fulfill the purpose of what?
A
visually and acoustically alerting team members and foremen to problem incidences and leading them to the site of the problem.
7
Q
Poka Yoke helps to avoid and identify what type of errors?
A
unintentional errors
Poka = errors, Yoke = avoidance
8
Q
What are the three Poka Yoke methods/principles?

16
Q
What is the rule of 10?
A
After each quality assurance level it will cost 10 times more in terms of time and money to correct and fix a defect than in the prior stage. The earlier you can find a failure or a risk, the cheaper it is for you and the company!
17
Q
What is failure detection?
A
- The organization is able to detect failures in process flows (directly or indirectly).
- For this purpose, tests are installed on or in the process.
- The organization derives measures on the basis of the detected failures.
18
Q
What is early failure detection?
A
- The preventive approach in the company turns fault detection into early fault detection.
- The organization is able to install the error detection directly after the location of occurrence
- The passing on of an failure to the subsequent process and in particular to the customer is excluded.
19
Q
What is failure avoidance?
A
- The organization detects deviations before they occur at the customer’s site
- If a failure has occurred at the customer, the organization tries to avoid a recurrence of the error. For this purpose, the Failure Mode and Effects Analysis (FMEA) must be adapted, for example, as new risks arise.
20
Q
What does FMEA stand for?
A
FMEA (Failure Mode and Effects Analysis)
21
Q
What is FMEA used for?
A
is a tool for failure avoidance & detection at the shopfloor.
22
Q
What is D-FMEA?
A
Design Failure Mode and Effects Analysis
23
Q
What is P-FMEA?
A
Process Failure Mode and Effects Analysis
24
Q
What is the output of FMEA?
A
RISKS which are quantified and analyzed
25
When do you start FMEA in a project?
ASAP-- find failures and begin actions
The earlier you start the earlier you can eliminate failures
26
What is the meaning of FMEA RPN and how do you calculate it?
Risk Priority Number
Calculated by severity x occurrence x detection
Severity is the input-factor for the RPN that cannot change over a lifetime of FMEA
27
Why is it important to do a S(severity) x O(occurrence) matrix?
To determine how severe the risk is
Low, medium, high, critical
28
Why is FMEA important?
It is a predictive quality tool for failure avoidance; eliminate/minimize risk before they happen
29
Who do I need for my FMEA project team?
FMEA moderator
| People who are aware of the customer requirements, design, and knowledge of the process
30
When you have a high rate of occurrence inside of the D-FMEA, what do you need to do?
You must eliminate the causes of the failure or you need to control
31
Which statements are correct about FMEA?
* The meaning of FMEA is Failure Mode and Effects Analysis
* When I have a claim of my component I should need to update my FMEA
* The maximum Risk Priority Number (RPN) is 1000
* I can have risks with a low Risk Priority Number (RPN) but with a high risk because of Severity x Occurrence
32
What is the correct sequence for FMEA steps?
1. Part structure
2. Function tree
3. Failure tree
4. D-FMEA with corrective loops
5. P-FMEA with corrective loops
33
When referring to quality, which statements are true?
* If I meet the customer requirements, then my level of quality is good
* In order to evaluate the quality of a product or service, I first need to know what the requirements are for this product
* If I deliver a cheap car with the basic equipment to my customer without any mistakes, the quality is better than if I deliver a luxury car with the full equipment and a faulty radio
* Checking quality is good. Avoiding risks in advance is much cheaper for my company
34
How many quality feedback loops does Daimler have?
8 quality feedback loops (QFL) along the value chain
35
What is the four-eye principle?
QFL 1- Worker self-control
QFL 2- Quality Gate
QFL 3- Inline Production Audit
QFL 4- Product audit
36
Which two function hold responsibility for QFL 1-4?
production and quality
37
What is the core idea of feedback loops?
is that a later loop controls an earlier one.
For that reason it is vital that each loop is operated by a different person.
In production the four-eye principle assures independent views between QFL 1-2 and QFL 3-4.
38
Failure detection eventually becomes what?
Early failure detection
39
