In-Depth Information
Undertake.to.interview.other.personnel.who.have.performed.the.job.in.the.past..
Consider.using.a.walk-through.as.part.of.the.interview.
Reviewing.records:.Review.relevant.documents.or.portions.of.documents.as.nec-
essary.and.reference.their.use.in.support.of.the.root.cause.analysis..Record.appro-

By.acquiring.related.information,.there.is.additional.information.that.an.evaluator.
should.consider.when.analyzing.the.causes,.including.the.following:
.
1.. Evaluating.the.need.for.laboratory.tests,.such.as.destructive/nondestructive.
failure.analysis
.
2.. Viewing.the.physical.layout.of.the.system,.component,.or.work.area;.devel-
oping.layout.sketches.of.the.area;.and.taking.photographs.to.better.under-
stand.the.condition
.
3.. Determining.if.operating.experience.information.exists.for.similar.events.at.
other.facilities
.
4.. Reviewing. equipment. supplier. and. manufacturer. records. to. determine. if.
correspondence.has.been.received.addressing.this.problem
PhAse II: Assessment
The.assessment.phase.includes.analyzing.the.data.to.identify.the.causal.factors,.sum-
marizing. the. indings,. and. categorizing. the. indings. according. to. cause.. Any. root.
cause.analysis.method.may.be.used.that.includes.the.following.steps:
