| Scope | For Cedar, decide whether to promise first productive training by week 70 and when to release the transformer package. Assume all starts at week 0 on one calendar, no resource leveling or hidden float, and these durations in weeks: utility readiness 44; manufacture to factory release 40; shipping to site 4; building readiness 42; installation after both dock delivery and building readiness 6; integrated facility acceptance after utility and installation readiness 4; IT delivery 46; racking after IT delivery and building readiness 2; cluster validation after facility acceptance and racking 6. An eight-week common supply disruption affects utility equipment and transformer manufacture together with probability 20%. An independent permit delay adds 16 weeks to building readiness with probability 10%; no other risks are modeled. The required confidence is 90%. These condensed teaching durations expose the electrical, building and IT interfaces described here; they are not supplier quotes or Cedar project observations. The calendar origin, predecessor links, common supply event and independent permit branch are exact enumeration conventions, not frequency estimates. Every duration is a selected teaching constant: factory/shipping end just after building readiness; utility precedes installation completion; IT/racking can run alongside the electrical path. The supply and permit increments deliberately bracket the path crossover. The event probabilities are chosen weights inside [0,1], not measured base rates; their independence and the shared utility/factory event are explicit dependence assumptions. The promise and confidence are sponsor preferences. Chapter 2.1 owns this network; a real Cedar release uses quoted durations and a project QSRA. |
