Plan from the supplied facts
Original planning graph is A→B, B→A and B→C. Arrows mean the components need joint integration readiness, not that a person must complete one before starting the other. A and B are mutually reachable, so plan them as group G; the grouped graph is G→C. Internal coordination remains to be designed.
| Node | Mutually reachable with | Planning group |
|---|---|---|
| A | B | G={A,B} |
| B | A | G={A,B} |
| C | No other node | C |
Work through the choice
The group exposes external dependencies while acknowledging the internal cycle. Its internal integration work still needs a plan.
Can A,B,C be claimed as an internal precedence order for the original arrows?
Show the worked answer
No. A→B and B→A cannot both be satisfied by a strict linear order. The usable external order is group G before C.
Material to use in your plan
Mark mutually reachable nodes, give each group a planning identity, and draw edges between groups. Record internal integration work separately rather than hiding the cycle.
