Composite Specification Cascade

This topic explains the cascade engine with respect to the cascading of composite specification status.

Specification Assessments

A SSA's Composite Specification Status is set to Not Tested upon creation or when a result is cleared.

The following statuses, or some thereof, can be set for a composite specification status at various levels in the job:

Composite Specification Status	Definition
Not Tested	No assessment is made as yet.
Not Required	No assessment is required for the result.
Pass	The result passes assessment limits.
Ignore Warning	An assessed warning is ignored.
Ignore Failure	An assessed failure is ignored.
Ignore Lower Failure	An assessed lower failure is ignored.
Ignore Upper Failure	An assessed upper failure is ignored.
Ignore Trend Failure	An assessed trend failure is ignored.
Warning	The result passes assessment limits with a warning.
Lower Warning	The result passes assessment limits with a lower warning.
Upper Warning	The result passes assessment limits with an upper warning.
Trend Warning	The result passes assessment limits with a trend warning.
Failure	The result fails assessment limits.
Lower Failure	The result fails assessment limits with a lower failure.
Upper Failure	The result fails assessment limits with an upper failure.
Trend Failure	The result fails assessment limits with a trend failure.

When a SSA receives a result, the result is assessed against all specifications on the sample, to set the SSASpecification's Specification Status.

A SSASpecification's Specification Status is set to:

Not Tested at sample scheme analyte creation or by clearing a result.
Not Required when Assessing Results against Scheme or Surrogate Limits following result entry of a non-numeric data type, or there are no specification scheme version analyte limits to apply.
Lower Failure, Lower Warning, Pass, Upper Warning or Upper Failure when Assessing Results against Scheme or Surrogate Limits following result entry of a numeric data type and there are specification scheme version analyte limits to apply.
Trend Warning or Trend Failure when Assessing Results against Scheme or Surrogate Limits following result entry and an assessment script on the analytical type sets it.

Composite Specification Status

After specification and QC assessment occurs, the cascade engine sets the SSA's Composite Specification Status and Composite QC Status:

Assessed against...	...to set	Cascades to...	Cascades to...	Cascades uses...	...to set
Scheme limits	SSA's Scheme Limit Status			SSA's Scheme Limit Status	SSA's Composite QC Status
Standard lot specification limits	SSA's Standard Status			SSA's Standard Status
SVA's precision limits	SSA's Precision Status			SSA's Precision Status
Each SampleSpecification's specification limits	SSASpecification's Specification Status	SSA's Composite Specification Status	Sets the SSA's Specification Status by considering the SSA Specification's Specification Status for the sample's Primary Specification, such that, where the SpecificationSVA's Critical for Validation is selected, then sets it to the SSASpecification's Specification Status, otherwise sets it to Not Required.	SSA's Specification Status

Cascading Composite Specification Status up through the Job

A Composite Specification Status is exactly that—a composite of the Composite Specification Status flags at the level below.

When a result is entered in context of a non-laboratory-batch job, the cascade engine cascades to each level of SS, Sample, Job, JSA and JS within the production, proposal or template job.

When a result is entered in context of a laboratory-batch job, the cascade engine cascades to each level of SS, Sample, Job, JSSA and JS first within the laboratory batch job, and then within each related original job.

The following statuses are possible for a Composite Specification Status at various levels in a job.

Composite Specification/QC Status	Definition
Not Tested	The initial state of specification assessment.
Not Required	The specification assessment is not required for the sample due to its Primary Analytical Type or Secondary Analytical Type or assessment limits not being available.
Pass	The specification assessment has passed. This means no failure exists on the contributing specifications on the sample (for the primary and non-primary specifications).
Warning	At least one result that underwent specification assessment returned a warning.
Lower Warning	The specification assessment of a result was below the lower warning limit.
Upper Warning	The specification assessment of a result was above the upper warning limit.
Trend Warning	The specification assessment of a result failed trend analysis for warning limits.
Failure	At least one result that underwent specification assessment returned a failure.
Lower Failure	The specification assessment of a result was below the lower failure limit.
Upper Failure	The specification assessment of a result was above the upper failure limit.
Trend Failure	The specification assessment of a result failed trend analysis for failure limits.

After this, the sample scheme analyte's Composite Specification Status is set to cascade as a composite of those on the sample scheme analyte specifications, to give an overview of all specifications linked to the sample scheme analyte.

All SSASpecs' Specification Statuses	SSA's Composite Specification Status
Not Tested in all	Not Tested
None contain Failure, Warning, Pass Not Required in any	Not Required
None contain Failure or Warning Pass in any	Pass
None contain Failure Warning in any	Warning
Failure in any	Failure

Note: Composite Specification Status flags do not need to be ignored as they do not effect Workflow Status flags, so are therefore not associated with any process to ignore a failure.
