Study Notes

Quality Control and Assurance

The main outputs of quality control are: acceptance decisions, rework, and process adjustments.

Seven Basic Tools of Quality

Flowcharts: graphic displays of process logic and flow, used to analyze problem occurrence and process improvement.
Run Charts: display the history and pattern of variation of a process over time.
Scatter Diagrams: show the relationship between two variables.
Histograms: bar graphs of a distribution of variables.
Pareto Charts: histograms that help identify and prioritize problem areas.
Control Charts: graphic displays of data that illustrate process results over time, used to prevent defects.
Cause-and-Effect Diagrams: aka fishbone or Ishikawa diagrams, used to find the root cause of a problem.

Inspection Checklists

Data faults:
- Are all program variables initialized before their values are used?
- Have all constants been named?
- Should the upper bound of arrays be equal to the size of the array or Size -1?
- Is a delimiter explicitly assigned for character strings?
- Is there any possibility of buffer overflow?
Control faults:
- Is the condition correct for each conditional statement?
- Is each loop certain to terminate?
- Are compound statements correctly bracketed?
- Are all possible cases accounted for in case statements?
- Is a break included after each case in case statements?
Input/output faults:
- Are all input variables used?
- Are all output variables assigned a value before they are output?
- Can unexpected inputs cause corruption?
Interface faults:
- Do all function and method calls have the correct number of parameters?
- Do formal and actual parameter types match?
- Are the parameters in the right order?
Storage faults management:
- If components access shared memory, do they have the same model of the shared memory structure?
- If a linked structure is modified, have all links been correctly reassigned?
- If dynamic storage is used, has space been allocated correctly?

Quality Assurance

Quality assurance includes all activities related to satisfying relevant quality standards for a project.
Another goal of quality assurance is continuous quality improvement.
Performing Quality Assurance through:
- Benchmarking
- Quality audits

Testing

Many IT professionals think of testing as a stage that comes near the end of IT product development.
Types of Tests:
- Unit testing
- Integration testing
- System testing
- User acceptance testing

Testing Limitations

Watts S.Humphrey defines a software defect as anything that must be changed before delivery of the program.
Testing does not sufficiently prevent software defects because it does not cover all possible scenarios.

Program Inspections

These are peer reviews where engineers examine the source of a system to discover anomalies and defects.
Inspections do not require execution of a system, so they can be used before implementation.
