Inside the guide

A configured portal is only the start.

The useful question: can people complete the agreed work, with reliable data and clear ownership?

03–06

Diagnose

Name the failure, define acceptance and assign the decision.

07–14

Design

Model records, reconcile a migration, control access, sync and workflows.

15–17

Release

Rehearse the change, measure completed work and decide what goes live.

18–21

Apply

Four fillable worksheets: decision record, field authority, acceptance test and release gate.

22–23

Evidence

Fifteen primary sources, with the limits of each research finding.

99.7% imported.
Still a no-go?

In the worked example, 1,844 of 1,850 expected records are created: a 99.68% reconciliation rate. Six records are rejected and two expected associations are missing.

A percentage cannot tell you whether one of those records is an active customer or a missing relationship contains a critical handoff. Before release, classify exceptions by business impact and agree who can accept the remaining risk.

Illustrative calculation from page 9. Constructed numbers explain the control; they are not client data or a benchmark.

The operating principle

Count what happened.
Check what matters.
Name who decides.

The guide turns that principle into record matching, field authority, workflow tests and release decisions.

Read an excerpt · page 4

Name the failure.
Then fix the cause.

Follow the affected record through the process. Identify the first point where its actual state differs from the agreed outcome.

Reports disagree.

Check the definition, cohort and date field. Trace a sample from the original record to the dashboard.

Records multiply.

Check what identifies one customer or opportunity. Inspect the matching keys and the sources that write them.

Owners keep changing.

Check which system or team may assign ownership. Compare property history with the applicable routing rule.

The full diagnostic continues in the PDF. Fifteen primary references support the product constraints and research appendix. Examples are explicitly illustrative; no client outcomes or universal failure rate are claimed.
