ITEC 3505 Week 10

Planning Quality Management

• Imply the ability to anticipate situations and prepare actions to bring about the desired outcome

System outputs

screens and reports the system generates

Performance addresses

how well a product or service performs the customer’s intended use

Managing Quality

Quality assurance includes all the activities related to satisfying the relevant quality standards for a project

Five Kanban Properties

• Visual workflow

• Limit work-in-process

• Measure and manage flow

• Make process policies explicit

• Use models to recognize improvement opportunities

Acceptance decisions

Determine if the products or services produced as part of the project will be accepted or rejected

Cause & effect diagrams

Trace complaints about quality problems back to the responsible production operations

Control chart

• Graphic display of data that illustrates the results of a process over time.

• Determine whether a process is in control or out of control.

  • When a process is in control, any variations in the results of the process are created by random events.

  • When a process is out of control, variations in the results of the process are caused by nonrandom events

    • You need to identify the causes of those nonrandom events and adjust the process to correct or eliminate them.

7 run rule

If seven data points in a row are all below the mean or above the mean, or are all increasing or decreasing, then the process needs to be examined for nonrandom problems.

Histogram

• Bar graph of a distribution of variables.

• Each bar represents an attribute or characteristic of a problem or situation

• The height of the bar represents its frequency

Pareto Chart

• Histogram that helps identify and prioritize problem areas.

• The variables described by the histogram are ordered by frequency of occurrence.

• Help identify the vital few contributors that account for most quality problems in a system.

Pareto analysis

• Referred to as the 80-20 rule

• 80 percent of problems are often due to 20 percent of the causes.

Flowcharts

• Graphic displays of the logic and flow of processes

• Help analyze how problems occur and how processes can be improved.

• Show activities, decision points, and the order of how information is processed.

Run chart

• Display the history and pattern of variation of a process over time.

• A line chart that shows data points plotted in the order of occurrence.

• Perform trend analysis and forecast future outcomes based on historical results.

Six Sigma

is uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving, and reinventing business processes.
