The useful starting point
A factor map is useful when its rows ask different questions and their relationships are examined. More boxes do not automatically mean more supported causes.
Treat a broad label as a starting question
The draft conclusion says operator error. That phrase does not identify the decision, the information available, or the conditions around it. Replacing it with management failure would be equally incomplete without evidence. A useful analysis describes the specific factors it can support and asks how they interacted.
Start by rewriting the outcome without assigning a cause: a package reached the wrong internal collection point. Then list the proposed factors beside the evidence needed to examine them. You are building an inquiry map, not distributing a fixed share of blame among people or departments.
Map a fictional wrong-destination delivery
The classroom packet contains a route card, a display screenshot, and a handover note. Each is fictional.
| Potential factor | Available item | Unresolved question |
|---|---|---|
| Destination information | Route card names point B | Was this the applicable card at the time? |
| Display information | Later screenshot names point C | What did the display show during the task? |
| Handover | Note says route changed | Who received the change and what did it mean? |
| Verification arrangement | No description supplied | How were conflicting instructions resolved? |
No row is automatically a confirmed cause. The table shows distinct questions rather than four versions of the same accusation.
Consider how factors might interact
Suppose later evidence confirms that both instructions were available and disagreed. That would make the conflict relevant, but you would still need to understand how the task was organized around it. Did the process identify an authoritative source? Was a change communicated in a usable way? Did the task include a decision point for resolving uncertainty?
These questions can connect information and organizational arrangements without assuming anyone's motive. Avoid forcing every factor into an independent chain when the issue may involve their combination. Equally, do not claim that everything contributed merely because it appeared somewhere in the packet.
Choose the next evidence question deliberately
Rank the open questions by how much their answers could change the explanation. Confirming which instruction applied may be more informative than collecting another copy of the same later screenshot. Record which question a requested item is meant to answer so the map does not become an unstructured document collection.
OSHA's general investigation guidance encourages looking beyond immediate explanations. This fictional map applies that idea as a reasoning exercise, not a Canadian legal test. A final study answer should identify the supported factors, their possible relationship, and the uncertainty that remains rather than announce one universal root cause.
Check your reasoning.
The packet contains a conflicting route card and display. Can you conclude that both caused the wrong delivery?
Open the suggested reasoning
Not yet. Establish whether both applied and were available during the task, then examine how the conflict affected the decision. Their existence is a lead, not a complete causal finding.
