Dashboard

Statit e-QC's integrated dashboard makes it easy to identify the current status of operations and processes. Each process or portion of a process can be analyzed within a published report. The Statit e-QC menu groups published reports into categories and list each report group with an icon that indicates its status: Red, Yellow or Green.  

Close-up View of the Statit e-QC Menu

The status indicator "rolls-up" and reflects the worst status generated by all of the individual analysis included in the report. Click on a report name in the navigation menu to display a list that shows the status of each item in the report. Click on the report item names to view the specific chart or analysis for more detailed information.

Integrating Other Information

Statit e-QC can integrate a wide array of information from a variety of sources to provide a centralized application where users can go to access information about their operations. From within Statit e-QC, users can access information such as:

  • Process Documentation
  • Existing information within an Intranet
  • CAD, Process Diagrams, Flow Charts, etc.
  • ISO 9000 documents
  • Specifications
  • Existing Web Applications

Statit e-QC provides several ways for users to access this information:

  • Page displayed when Statit e-QC is first run
  • Page displayed when a user logs into Statit e-QC
  • Page displayed when user opens a folder in the menu
  • Page displayed when user selects a dynamic report from the menu
  • Links can be added to bars, data points or texts on a graph
  • Links can be added to the output from Statit e-QC reports

With e-QC, you can integrate diagrams from other sources and add "hotspots" (links) to provide an intuitive way for users to access the detailed information they need. When the user clicks on a hotspot, an e-QC report can be run to show a chart or analysis. Examples include displaying SPC charts for measurements from a part diagram, line or areas in a plant or facility, or clicking part of a process diagram and showing a Pareto for the number of defects at that particular part of the process.   [ back to top ]

Reporting Output

Statit e-QC supports a wide flexibility of output capabilities including:

  • Multiple graphs per page
  • Mixed graphics and text output
  • Font and color control of all graph components
  • Include text or HTML from a file and embed it in the output
  • Add HTML formatting to the output
  • Customize the output page template to add a company logo, navigation, links, etc.  [ back to top ]

Desktop Integration

Users can launch desktop applications directly from e-QC to further analyze the data they have selected. The data can also be saved locally to a file on the user's computer in a variety of formats including, Excel, Statit, Minitab, SAS and many others. This provides a way for a wide range of users to access data from a centralized server for further or additional analysis without needing a database connection on each computer. Statit e-QC output, such as images and text reports, can also be saved to a user's machine for inclusion into reports and presentations. See Data Files for a list of supported database formats.   [ back to top ]

User Accounts

Statit e-QC can support an unlimited number of login accounts.  Each login allows restricted access to specific areas or reports. When a user logs into Statit e-QC, the navigation menu displays only the areas or reports that the user is authorized to access.

Each login is classified as one of the following user levels:

  • Viewers
    Can view only the published reports which they have permission to access.  Viewers do not require a Statit e-QC license. Statit e-QC allows for unlimited access to scheduled reports by Viewers.
  • Users
    Can run dynamic and published reports which they have permission to access.  Users can also do the following tasks when working with dynamic reports:
    • Send output in an e-Mail message, and optionally attach the underlying data
    • View the data associated with the report within the browser
    • Launch an interactive Statit, Excel or other desktop application on the computers, with the data, for additional analysis
  • Authors
    Have the same capabilities as Users, with the additional capability of being able to develop and modify macros which they have permission to access.

Automated Reporting

Scheduling Reports

A report can be scheduled to run at regular intervals.  Reports can be scheduled to run frequently, as often as every 15 minutes, run on certain days of the week or certain days of the month.  The Status of each report is indicated on a dashboard in the Statit e-QC menu.

e-Mail Notification

A list of users can be automatically notified by e-Mail when a Statit e-QC Report is published or updated.  A different set of users can be notified only if a defined Alarm level for the report is met or exceeded.  e-Mail can also be sent to the Author or Administrator if the report generates certain errors, such as not being able to access the database.

The e-Mail message can contain a link that gives the recipient immediate access to the report, without logging into Statit e-QC. The e-Mail can be sent to a list of users and copied to other users.

Data in Statit e-QC

One of the fundamental features of Statit e-QC is its "open" approach to accessing data. 

Data Access

Rather than dictate a specific data source or implement a proprietary data storage mechanism, Statit e-QC takes an open approach to accessing data.  Statit e-QC can access data from any popular database as well as data files.  And Statit e-QC users can get data delivered to their desktops in a variety of formats for additional in-depth analysis or collaboration. 

Databases
Statit e-QC can access any ODBC 3.0 compliant data source using SQL.  All major database vendors have ODBC drivers for accessing data.  To access data, the proper ODBC driver is installed on the same server where Statit e-QC is installed.  End-users who access Statit e-QC do not need to have ODBC drivers installed.

Files
Data can be stored in a wide variety of file formats. Files can be read and written to the file system or to a URL location.

  • ASCII Data Files
    Read and write free-format ASCII files and files in a wide variety of fixed formats.
  • Binary Data Files
    Support flexible format specification to read and write binary formatted files .
  • Industry Files
    Read and write data in a wide variety of popular file formats:

Spreadsheet / Database

Data Manipulation

Statit e-QC provides a full range of data modification, manipulation, and transformation capabilities, including conditional transformations, subsets, sorting and ranking.

Many built-in functions for arithmetic, mathematic, statistical, and trigonometric transformations are provided.  String, date, and time manipulation functions are also provided.  Statit e-QC can:

  • Modify and compute new data items and variables
  • Perform conditional computations based on logical criteria, and can use the entire data set or only a subset of data
  • Change values, combine categories, or collapse intervals
  • Rank variable observations as well as lag or lead over time periods
  • Calculate moving averages and ranges
  • Format data for display
  • Convert data variables to other data types

Flexibility

Most of the variable and attribute control charts offer these features:

  • Data Table
    Presents a list of items to display below the chart. The choices include the underlying data, plotted values, control limits, etc. Other variables can also be specified.
  • Data Tips
    When the chart is viewed, the user can "mouse over" a data point or "hot spot" on the chart and pop-up window is displayed with additional information. This information can include underlying data, subgroups, rules and rule violations, control limits and other user-specified variables. Additional Data Tips can also be easily added to the chart.
  • Phases
    Once a process has been identified as needing improvement, the first step to improve that process is to establish the initial process "capability." Without doing this, there would be now way to tell whether a change made in the process results in an improvement. Statit's Phase Analysis provides for a comparison between the baseline process and new protocol (corrective action) to ascertain statistically, whether the new protocol is better, the same, or worse than the baseline process. This action corresponds to the "Study" step in Deming's Plan-Do-Study-Act cycle.
  • Assignable Cause
    Points on the chart can be excluded from control and warning limit calculations and rules testing. This feature is often used to identify out-of-control points, for which an assignable cause has been found. A comment can be displayed on the chart by the point.
  • Annotation
    Comments can be placed near any point on the chart. These comments automatically follow the point as it moves across the chart, when more data is collected. For example, this feature allows an operator to identify a point, add comments or additional information and save those comments back to the data source.
  • Limits
    There is a great deal of flexibility for displaying Control, Warning and Spec limits, including how they are computed, displayed and labeled.
  • Subgroups
    Subgroups can be identified either by the constant subgroup size or by a categorical variable, such as date and time or lot number.
  • Text Reports
    A text report can be requested which lists the control limits, rules tested and violated, and outliers.

Alarms

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

[ back to top ]

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

Using Expressions

Statit e-QC allows alarms to be defined as a result of an expression or calculation.  For example, one way of measuring how well a process is performing is to look at its CpK value.  Alarm levels could be divided up as shown below.

Statit e-QC Alarm Status
Expression Status
CpK  < 1.0
CpK  >= 1.0 and < 1.5
CpK  >= 1.5

[ back to top ]

Handling Alarms

Visual Notification

  • Identify specific SPC rule violations by placing an identifier next to the data point.  Statit e-QC does this automatically by displaying a letter which indicates the rule violated.  If the user clicks on the letter, a description of the rule is displayed as a Data Tip.
  • Change the colors of the graph.
  • Add a text message to the graph.
  • Include customized HTML effects like banners, blinking text and animated gifs.

Example of changing screen color and adding text messages

e-Mail Notification

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 report.

Other Alarm Handling

  • Perform additional analysis and generate additional charts automatically to help the user identify the problem.
  • Display instructions for handling the alarm or identifying possible causes.
  • Generate an output to file or database.
