Common Mistakes and Expert Pro Tips

1. Inadequate tech packs and vague specs

Without precise tech packs, misinterpretations lead to costly rework. Expert tip: lock in a standardized tech-pack template and require all new SKUs to include measurements, fabric specs, trims, construction details, and dye lot information. Use a digital repository to track revisions and approvals. Cost-saving: minimize revisions by validating specs in a pre-production sample before committing to larger runs.

2. Poor IP protection and NDA gaps

Neglecting IP protection can expose your designs. Expert tip: execute NDAs with clear scope, restrict access to proprietary files, and segment sensitive information (e.g., high-level concepts vs. technical drawings).

3. Selecting a supplier without due diligence

Rushing to select a garment manufacturer without audits or capability checks leads to quality and reliability risks. Expert tip: require at least two independent references or performance attestations. Use a formal scoring rubric and document reasons for final selection.

4. Overlooking compliance and sustainability

Ignoring compliance can derail shipments or damage brand reputation. Expert tip: incorporate third-party certifications and supplier self-assessments into the decision, and require ongoing compliance reporting. This also improves long-term quality and sustainability alignment.

5. Inflexible MOQs and hidden costs

Rigid MOQs or unexpected fees disrupt cash flow. Expert tip: negotiate flexible MOQs for pilot lines and early-stage launches, with clear cost structures for sampling, tooling, and re-sourcing. Transparent cost models help you forecast budgets accurately.

6. Inadequate pilot testing and quality gates

Skipping a rigorous pilot increases risk. Expert tip: implement a staged sampling plan with explicit tolerance thresholds and a go/no-go decision point before scaling. Document deviations and corrective actions for traceability.

7. Ineffective communication and escalation paths

Delays creep in when escalation channels aren’t defined. Expert tip: appoint a single point of contact on both sides, define response times, and use a central collaboration platform for all changes and approvals.

8. Lack of contingency planning

Supply shocks will happen. Expert tip: establish a backup fabric, a secondary trim supplier, and a regional sourcing plan to minimize disruptions and keep your exclusivity intact.
