From Schedule to Budget Ready

This week runs the last step of the process, the pressure test, live against a failure your schedule will recognize. Then comes the handoff, in which your locked schedule becomes exactly what Module 4 needs to price the project.

Pre-work · required · 10 minutes

Reopen your build, and bring one expensive task

Reopen your locked Schedule Builder build from Week 2, and read it once in both views. While you read, recall Week 3's rule, identify which tasks depend on a subconsultant, and note what has to be executed before each of those tasks starts.

Then look at your own current project and pick one task where a delay would cost the most, in dollars, not days. Bring that task to the session. The close asks for it by name.

Signature lineA schedule is not finished when the dates are set. It is finished when the next module knows exactly what to do with it.

What happens in the session

Step six, run against a live failure

Weeks 1 through 3 built and protected the plan. Week 4 runs the last step of the Schedule Development Process, the pressure test, three weeks after you built the plan, which is exactly when real schedules get tested.

SegmentWhat you do
Frame and recall · 5 minDisplay your locked schedule on screen, and recall Week 3's rule before anything new is introduced, no subconsultant works without a fully executed agreement.
Discipline tagging · 15 minMake two judgment calls for each task. The first asks which tasks a subconsultant likely performs, applying Week 3's make or buy question. The second asks which tasks carry schedule risk worth flagging for Module 4. The discipline tags themselves receive a quick confirmation pass, not this segment's focus.
Schedule Risk Spotter · 15 minThis segment is the pressure test. A subconsultant deliverable lands three weeks late. You select which downstream tasks and dates are actually at risk, then select the recovery approach, before the reveal.
Close and hand off · 10 minPost to the chat the one task from your own schedule for which a delay would cost the most money, and explain why. That answer addresses the exact question Module 4 opens with.

What am I supposed to know?

What a budget needs from a schedule

Module 4 does not start without information. It starts from your locked schedule, and it needs exactly three things from that schedule. Nothing here builds the budget, building the budget is Module 4's work. This week makes sure the schedule arrives ready for the budget process.

  • 1Discipline assignments, confirmed. Every task carries its discipline from the Work Breakdown Structure. The Project Cost Spreadsheet's own tip, grounded in Section 2.4, states that separating tasks by discipline makes tracking of finances easier. Today's confirmation pass applies that tip early.
  • 2Subconsultant flags. Every task a subconsultant likely performs is flagged. Subconsultants are priced differently than staff, carry their own funding line, and bring Week 3's executed agreement date with them.
  • 3Schedule risk flags. Every task for which a slip would compound downstream is flagged. A budget that knows which parts of the schedule are at risk of delay can hold contingency where it matters, instead of everywhere.
Grounded in the 2022 Weston & Sampson Guidelines, Section 4.2Controlling the schedule helps control the budget. This week is the first time the course reads Sections 4.1 and 4.2 together, and that one sentence is the connection between them.

Why a slip becomes a cost

The five budget busters

Section 4.1 names the five ways budgets fail financially. Read the list carefully. Three of the five are schedule problems that create cost impacts.

  • 1Poor estimation of time needed for tasks. A task duration that is guessed rather than confirmed becomes a cost overrun once the actual duration is known.
  • 2Schedule delays. This buster affects cost directly. Idle time, remobilization, and extended overhead all add to the project's total cost.
  • 3Scope creep. This is the risk the 60 percent gate warns about, now shown with its cost attached.
  • 4Different staff, skills, or salaries than planned. When a slip shifts a task into a period when the originally planned staff are no longer available, their replacements bill at different rates.
  • 5Rework. Rework is the most expensive way to complete a task twice, and it is the outcome the gates and reviews exist to prevent.

This is why the Schedule Risk Spotter scores a three week lab delay in dollars, not days. One late deliverable touches the memorandum, the gate date, the staffing plan behind the final design phase, and the advertisement date the Town announced. A schedule slip on one task compounds into cost on several others.

Capstone connection

One plan, three modules, second chapter written

The Milestone Schedule and Schedule of Activities you locked in Week 2, now tagged by discipline and flagged for schedule risk, are exactly what Module 4 needs to build the Project Cost Spreadsheet and price the project. Scope, schedule, and budget form one plan across three modules, and you have just written the second chapter.

Several concepts carry forward as well. The critical path and buffer concepts return whenever Module 4 reviews a schedule against a burn rate. The Certificate of Vote rule returns wherever a subconsultant is priced into the budget. The Project Gates you identified in Week 2 become the checkpoints Module 4 uses to explain how a budget gets reviewed and reforecast, rather than built once and left unchanged.
