Transformational Approach

This working example shows how Transformational Approach tests a project scenario after evidence and project records have been reviewed. Adjust the reference project below to examine the cost increase, schedule, and contingency assumptions — every output is a range traced to the Sustainable Gaps planning thesis's cited dataset. Select or focus a modeled result to inspect its basis and sources.

How this fits the SG system

Evidence becomes a scenario. A person makes the decision.

The calculator does not discover projects, approve evidence, or submit a bid. It tests approved inputs and leaves a reviewable basis for the next action.

  1. 01

    Qualified evidence

    Signal Engine and client records establish the source, date, and context.

  2. 02

    Visible scenario

    Change the assumptions and see which cost and schedule ranges move.

  3. 03

    Human decision

    The responsible estimator or leader accepts, rejects, or revises the action.

  4. 04

    Outcome review

    Compare the earlier scenario with what happened and improve the next model.

Weights are normalized. The mix drives your queue length and contingency.

Later starts meet shorter projected queues [e] — and higher ratcheted prices.

Same costs, two arrival modes

Earlier planning allows the project team to compare, price, defer, or reject an option before schedule pressure narrows the available choices. These modeled ranges change with the project inputs and do not guarantee final cost or delivery.

DERIVED Computed from sourced history.

JUDGMENT SG professional call, re-checked quarterly.

[e] Estimate or forecast — assumptions stated, never presented as measured fact.

Every output is a range, never a point — the honest shape of a forecast. Select or focus any result for its computation note and numbered citations; the full source list is in Assumptions & sources. Dotted-underlined terms carry plain-English definitions.
