Search programme management template consulting and the field has a real, settled answer. A dependency matrix shows the shape of the network, a dependency log carries a needed-by and committed-by date with an owner on each side, and a critical-path roll-up sequences the whole thing against the final date. That is genuinely good practice, and most of the leading templates in the category ship some version of all three. What none of them checks is where the committed-by date in that log actually comes from.
Read closely, the owner named on the providing side is usually whoever answered the request, not someone with visibility into that workstream's real schedule. The committed-by date next to their name is therefore often just the receiving workstream's own hope, typed into a column that looks like verification. This pack's register reads that date somewhere else: the providing workstream's own, independently maintained task register, for the specific task that produces the thing. Both numbers already exist in two documents. Nobody had opened them side by side.
Marrow Bridge Consulting's ERP programme for Thoreston Industrial Supply Co. sequences four workstreams against one date that cannot move: the legacy platform's vendor support expires 30 April 2027, after which, as NIST's own patch-management guide puts it, a fix "will never be released because the software is at end-of-life." On 10 February, Data Migration's own plan showed its data-cleansing task landing 17 days after Systems Integration's own plan had assumed, caught 20 days before that gap would otherwise have surfaced on its own.
