运作方式，逐步说明
贯穿平台的 3 个步骤 - 每一步做什么，以及为什么重要。
Find the long-lead items
采购Go through the procurement schedule for the items whose lead time is long against the programme, from switchgear to bespoke facades, and note the date each is actually needed on site.
原因: A long-lead item nobody flagged is the one that stops a trade dead. Finding them early is what gives you the weeks you need to order in time instead of expediting at a premium later.
Tie order dates to the programme
高级进度计划Work back from each required-on-site date through the lead time to the date the order must be placed, and set those order-by dates as milestones on the programme the team works to.
原因: A required-on-site date on its own does not tell procurement when to buy. Backing the lead time onto the programme is what turns a delivery need into an order-by milestone somebody is accountable for.
Report the remaining exposure
报告Report which long-lead items are ordered against plan and which order-by dates are slipping, so the items still at risk to the programme are visible to the team at every review.
原因: A procurement risk you cannot see is one you manage by luck. Reporting the exposure keeps the slipping items in front of the people who can expedite them before they become a delay on site.
