/ THE SHORT ANSWER
- 01Identify critical parts, qualify alternatives, compare total cost and risk, test samples, define allocation rules, and maintain readiness.
- 02The useful starting point is one bounded process, one accountable owner, a trustworthy baseline, and a review cadence that reaches the factory floor.
- 03Identify parts by failure consequence and recovery time.
- 04Evidence and ownership should be designed before automation or scale.
/ dotSuper point of view
The useful starting point is one bounded process, one accountable owner, a trustworthy baseline, and a review cadence that reaches the factory floor.
Start with the decision, not the tool
Dual sourcing does not require equal inventory or volume.
It requires a credible alternate path whose technical, commercial, tooling, quality, and approval conditions remain current.
The useful starting point is one bounded process, one accountable owner, a trustworthy baseline, and a review cadence that reaches the factory floor.
This guide separates verified source guidance from dotSuper's implementation model so teams can see what is required, what is recommended, and what still needs professional judgement.
The control model for supplier management
The following controls form a practical minimum.
Their depth should increase with consequence, volume, dependency, and difficulty of recovery.
Assign one accountable business owner.
Supporting teams can operate parts of the process, but unresolved handoffs should not become silent gaps between policy, software, vendors, and daily work.
- Identify parts by failure consequence and recovery time.
- Check drawings, tooling, approvals, and intellectual property.
- Qualify supplier, process, sample, and logistics.
- Define allocation and readiness review rules.
Run the work as a visible operating loop
Each stage should produce evidence for the next stage and a named route for exceptions.
Start with representative cases rather than the easiest example.
The sequence below is dotSuper's implementation model, not a statutory or certification formula.
Adapt it to the organisation's systems, decision rights, sector, workforce, and current maturity.
| Stage | Work | Exit evidence |
|---|---|---|
| Observe | Study normal work and exceptions at the workplace | Critical-part map |
| Baseline | Agree definitions and collect representative evidence | Alternate qualification record |
| Design | Set ownership, controls, thresholds, and escalation | Total-cost and risk comparison |
| Pilot | Run one bounded area with frontline participation | Allocation and readiness review |
| Improve | Compare results and standardise only what works | Allocation and readiness review |
Keep evidence that supports a real decision
Store enough context for a reviewer to reconstruct the decision without relying on memory.
Track a small set of outcome and control measures.
Review ageing, exceptions, rework, recurrence, override, and completion quality alongside speed or volume.
A faster weak process is not an improvement.
- Critical-part map.
- Alternate qualification record.
- Total-cost and risk comparison.
- Allocation and readiness review.
Avoid the failure patterns that create false confidence
Teams then optimise completion while the actual decision, risk, or customer outcome remains unchanged.
Review the following patterns during design and again after the first month.
Treat recurrence as evidence that the workflow or ownership needs repair, not merely that an individual needs another reminder.
- Starting with a platform purchase.
- Optimising one department while shifting loss elsewhere.
- Closing actions without checking the result at the workplace.
Use the first 30 days to prove the workflow
Choose one business unit, system, process, supplier group, machine, or use case where the owner can provide evidence and act on findings.
Freeze the baseline before changing the process.
At day 30, decide whether to stop, repair foundations, continue the pilot, or scale to an adjacent scope.
Do not describe wider rollout as success until quality, ownership, evidence, and economics hold outside the original case.
| Week | Focus | Deliverable |
|---|---|---|
| 1 | Scope and baseline | Owner map, current workflow, and critical-part map |
| 2 | Control design | Approved controls, decisions, and alternate qualification record |
| 3 | Representative pilot | Normal cases, exceptions, and total-cost and risk comparison |
| 4 | Review and next decision | Measured result, open risks, and allocation and readiness review |
Where dotSuper can help
The engagement starts with the current process and evidence, then builds the smallest controlled intervention the team can own and measure.
dotSuper does not replace legal counsel, auditors, certification bodies, safety professionals, or regulated decision-makers.
It helps convert approved requirements and operating knowledge into clear data, workflows, controls, interfaces, automations, and review evidence.
What this page cannot conclude
- 01Drawings, tooling, exclusivity, export controls, customer approvals, and regulated changes may constrain alternate sourcing.
- 02The workflow and 30-day cadence are dotSuper operational synthesis, not an official legal, regulatory, audit, or certification method.
- 03Technology, automation, AI, and dashboards do not remove the need for accountable human decisions and appropriate professional review.
- 04Outcomes depend on source quality, participation, system access, operational discipline, and the organisation's ability to act on findings.
