Liftoff of Apollo 13
“Houston, we’ve had a
problem here.”
Mattingly has a problem caused by
Duke…
…which creates an opportunity for Swigert…
…which soon becomes a
new problem.

Functional Decomposition
Continually redefining the system under study into subsystems until reaching a point where no further value is gained from additional subsystem identification.

Typical PIECES AnalysisSymptom P I E C E SManagement reports are often not received on time. X Production line throughput is below expected standards. X Product rework is high. X X Inventory control reports are inaccurate. X Exceptions occur frequently and must be processed by hand.
X
Production time is higher than industry average. X Orders are often cancelled due to excessive delivery wait time.
X Required information to process an order not available on demand.
X Organizational data redundancy is high. X Production lines are often down for repair or maintenance. X Line personnel are often not aware of their production quota.
X Data transferred from production system to sales system by hand.
X X
Several incidents of system sabotage have been recorded. X
