risk.factors.to.exist..MORT.(or.Mini-MORT).is.used.to.prevent.oversight.
in. the. identiication. of. causal. factors.. It. lists. on. the. left. side. of. the. tree.
speciic.factors.relating.to.the.occurrence;.and.on.the.right.side.of.the.tree,.
itĀ lists.the.management.deiciencies.that.permit.speciic.risk.factors.to.exist..
Management.factors.support.each.of.the.speciic.barrier.and.control.factors..
Included.is.a.set.of.questions.to.be.asked.for.each.of.the.barrier.and.control.
factors. on. the. tree.. As. such,. they. are. useful. in. preventing. oversight. and.
ensuring.that.all.potential.causal.factors.are.considered..It.is.especially.use-
ful.when.there.is.a.shortage.of.experts.of.whom.to.ask.the.right.questions..
However,.because.each.management.oversight.factor.may.apply.to.speciic.
barrier.and.control.factors,.the.direct.linkage.or.relationship.is.not.shown.
but.is.left.to.the.analyst..For.this.reason,.Events.and.Causal.Factor.Analysis.
and.MORT.Analysis.should.be.used.together.for.serious.occurrences:.one.
to.show.the.relationship,.the.other.to.prevent.oversight..A.number.of.con-
densed.versions.of.MORT,.called.Mini-MORT,.have.been.produced..For.a.
major. occurrence. justifying. a. comprehensive. investigation,. a. full. MORT.
analysis. could. be. performed. while. Mini-MORT. would. be. used. for. most.
other.occurrences.

formance..The.focus.of.this.analysis.method.is.on.operability,.work.environ-
ment,.and.management.factors..Man-machine.interface.studies.are.frequently.
done.to.improve.performance..This.takes.precedence.over.disciplinary.mea-
sures..Its.focus.is.on.operability.and.work.environment,.rather.than.training.
of.operators.to.compensate.for.bad.conditions..Human.Performance.Evalu-
ations.may.be.used.to.analyze.most.occurrences,.since.many.conditions.and.
situations. leading. to. an. occurrence. have. ultimately. originated. from. some.

6.. Kepner-Tregoe Problem Solving and Decision Making .provides.a.system-
atic.framework.for.gathering,.organizing,.and.evaluating.information.and.
applies. to. all.phases. of. the. occurrence. investigation. process.. Its. focus. on.
each.phase.helps.keep.them.separate.and.distinct..The.root.cause.phase.is.
similar. to. change. analysis.. Kepner-Tregoe. is. used. when. a. comprehensive.
analysis. is. needed. for. all. phases. of. the. occurrence. investigation. process..
ItsĀ strength.lies.in.providing.an.eficient,.systematic.framework.for.gather-
