- 1What is COQ (Cost of Quality) and how it relates to software quality and testing?Amount of money spent more than the cost to build the product right the first time. Reduce rework, If 0 defects the first time COQ would be 0
- 2Prevention CostAmount of money spent to reduce the possibility of defect being introduced in the first place. Includes training, tools, Audits, process improvement. 3% of cost (QA activities)
- 3Appraisal CostsAmount spent to check finished products against requirements but not before product is shipped. (Testing costs like reviews, inspections, Unit tests, etc) 7% of cost
- 4Failure CostsAmount of money spent on fixing defects after product is shipped (Rework, fixing prod defects, Correcting incorrect requirements, etc) 40% of cost
- 5What is the PDCA (Plan, Do, Check, Act) and how it affects quality activities.Illustrates continuous improvement. (Demming Wheel) First you Plan your work, then you do (includes training and defining objectives), you want to constantly check that you are on the right track, then make improvements on observations
- 6What is a risk matrix and be familiar with CSF's (Critical Success Factors)Is used to determine which CSF are the most important to a customer. Factors that are most important are listed first in the matrix
- 7Critical Success FactorsCorrectness, Reliability, Interoperability, Testability, Ease of Use, Resusability, I, Usability, Maintainability,
- 8What is a quality plan and who participates in the development of it?x
- 9Define the differences between tactical and strategic testing activities.strategic test activities are high level (Master TP and strategy documents)
Tactical = how we are going to accomplish this (test plans etc.) - 10Define root cause analysis and also explain the difference between common and special causes of variation.Root cause analysis - explaining how the fault was introduced. e.g. faulty requirements. SCV - Something that is hard to plan for and that does not happen often. CCV - are things like forgetting to test a module.
- 11Define a quality policy and why it is important.x
- 12Define "structured" approach to testing and explain the V-model concept.x
- 13Define "how much testing is enough".x
- 14Define the difference between verification and validation test activitiesc
- 15Name two structural and two functional test activities.x
- 16Define a workbench and explain the four main components.c
- 17How is maintenance testing different from new development testing and how is regression testing different?c
- 18What is the single most valuable static test technique available to testers?Reviews
- 19How do you differentiate a spec from a requirement?Requirements comes directly from a user and is what the customer wants. Spec is restatement of the functional code into psuedo code and is more detailed.
- 20What are 6 of the main components of a test script?c
- 21What are the 3 components of a test case?1. Condition to be tested
2. Steps/Procedures to run test
3. Expected results - 22What is the difference between a test case and a test script?TC is simple and is run manually
TS is usually automated and can contain hundreds of TC's - 23How are internal controls built into software systems and subsequently how are these controls tested?q
- 24Name at least 3 types of quality tools (not vendors).Code inspectors, Diagramming tools, Presentation tools, Test case management tools.
- 25Explain the difference between QA and QC.QA means defect prevention. QC defect detection.
- 26Give an example of a standard.100 percent of the functionality must be tested
- 27Define 5 major components of a quality and test plan.1.Function to be tested
2.Test environment
3.tools to be used
4.Constraints
5.How to handle defects - 28What are the drawbacks of using production data to test?q
- 29What are 5 major components of a good test report?d
- 30What are defects and how are they managed and eliminated?Defects are a variation from requirements. They are managed by using processes to prevent them and methods to detect them.
- 31What is a Pareto Chart and how is it used in quality?Used to represent the 80/20 rule. In quality shows the most common sources of defects
- 32What is an Ishakawa diagram and how is it used in quality?Fishbone diagram, Cause effect diagram. Used to visualize possible causes of problems with process, products or services
- 33Give a brief summary of how you would justify the expense of continuing to test versus stopping testing (due to deadlines, for example).q
- 34StandardRequirement of process or product. eg. 100 % of a function must be tested
