How does Statit e-QC handle specification limits?

Statit e-QC can retrieve specification limits from any supported data source and display them on the chart. As an example, many customers retrieve data from their manufacturing database, but keep specification limits in a spreadsheet on their desktop. Statit can retrieve data from both locations for reporting purposes.

Can users interactively add comments and assignable causes for subgroups?

Yes. Statit e-QC can display annotation, identify assignable causes and display phases or stratifications on charts. This information can be retrieved from a database and automatically displayed on the graph when it is requested. Statit e-QC reports allow users to click on data points and enter comments or identify an assignable cause for that data point. Once entered, the information can be written back to a database for archive and automatically displayed on the graph.

Example: user is allowed to interactively add comments, assignable cause and phases to the chart

Can I customize my own SPC rule sets?

Yes. Statit e-QC allows modification of existing rule sets such as Western Electric and AT&T, and creation of new rule sets.

Alarms

See also Alarms.

Can Statit e-QC send email or update a dashboard when an alarm is detected?

Yes, Statit e-QC provides flexible methods for defining and responding to alarms. Statit e-QC allows alarms to be classified into four different levels.

Statit e-QC Alarm Levels

Alarm State

Value
Red
Exceeded alarm value or last point out-of-control
Yellow
SPC rule violation or between alarm and target value
Green
No rule violations or met target value
Normal ball_normal.gif (163 bytes)
No rule violations or no target/alarm value set

Defining Alarms

Statit e-QC provides users with the freedom to define the Alarm State using SPC or Business Rules Testing or as the result of a specified expression or statistical calculation.

Using SPC Rules Testing

Statit e-QC comes standard with the AT&T/Western Electric, Ford, Nelson and JCAHO rule sets for SPC charts. Statit e-QC also allows modification of existing rules sets and creation of new rule sets.  

Alarm conditions can be raised in a variety of ways including:

  • Last point out of control
  • Any point out of control
  • Specific rules violated
  • Rules violated in last n samples

When Statit e-QC reports are scheduled, users can be automatically notified by e-mail when certain alarm conditions are met or exceeded.

Example: email message received with link providing direct access to the report.
