For procurement teams, an approved packaging specification must perform reliably across every order and operating site. Achieving that consistency requires coordinated testing, documented specification control, meaningful supplier KPIs and continuity planning. METHOD 360® brings these disciplines together through an end-to-end packaging methodology, providing a structured approach to packaging performance management and supply risk.

What Drives Consistent Packaging Performance
Consistent packaging performance depends on five controls: documented specification, pre-supply testing, change control, performance measurement and continuity planning. Applied together across repeat orders, they turn an approved product into a standard that procurement teams can audit.
-
Documented specification
A documented specification records agreed dimensions, tolerances, material grades and performance criteria in one controlled file. Specification lock holds those requirements constant across repeat orders; every delivery is assessed against the approved product.
- Pre-supply testing and fit validation
Pre-supply testing verifies that production-representative samples will perform as required before volume orders are placed. Trials should confirm compatibility and performance under real operating conditions, using the customer’s equipment where practical. Criteria and results should be clearly recorded, especially when specifying packaging for automated machinery. - Change control
Packaging change control prevents an approved product from being altered without review. Contracts should require advance notification of changes to materials, processes, tooling, sources or production sites, followed by assessment and named sign-off. These controls are key to preventing packaging specification drift. - Performance measurement
Data-driven performance measurements test the supply relationship against agreed outcomes. A supplier scorecard should combine fulfilment, quality and delivery KPIs with packaging yield, reject rates and corrective-action data. Baselines and trendlines make deterioration visible earlier than isolated monthly figures. - Continuity planning
Continuity planning protects approved packaging during demand changes or disruptions. It should combine intelligent demand forecasting, defined safety-stock rules, lead-time monitoring and pre-approved alternative sources. Any alternative source must meet the same specification and qualification requirements before use.
Together, these controls produce repeatability across sites and repeat orders. METHOD 360® applies all five within a single managed packaging supply model.
Inside METHOD 360®: An End-to-end Packaging Methodology
Method 360 is GM Packaging’s end-to-end packaging methodology: a managed packaging supply model spanning sourcing, manufacturing, packaging innovation, printing, global logistics, storage, delivery and stock control.
Method 360 applies the controls above in one connected process, spanning the six pillars essential to effective packaging output: space, waste, efficiency, liquidity, sustainability and growth.
Space
Method 360 holds your packaging stock off-site and delivers exactly what you need, when you need it. This just-in-time approach removes bulky pallets from the production floor, freeing up space for core operational tasks rather than static storage.
Waste
Method 360 right-sizes your packaging and forecasts usage against actual consumption. Optimising stockholding from our climate-controlled facilities prevents degradation, cuts excess ordering and lowers write-off costs, without leaving your production lines short.
Efficiency
Method 360 optimises your fulfilment workflow, particularly during peak, supplying multiple packaging lines through one account with electronic ordering and invoicing and scheduled deliveries. Your team raises fewer orders, checks fewer invoices and chases fewer suppliers, with one named contact to call when something needs resolving.
Liquidity
Buying in bulk usually traps working capital on your warehouse shelves. Method 360 harnesses your volumes and holds that inventory upstream, so supply sits with those who can deliver it when you need it and your capital stays available.
Sustainability
Method 360 delivers kerbside-recyclable, responsibly sourced and plastic-free packaging options that support environmental targets without compromising durability, food safety or performance on automated packaging lines. Product-specific materials, food-contact compliance and recycling guidance should be verified for the intended application.
Growth
Scaling a business requires supply chain stability. GM provides the global logistics infrastructure necessary to support multi-site expansion, ensuring every new location receives identical, high-performing packaging that protects your brand standards and customer experience as your footprint grows.

Measure Packaging Supplier Performance
Turning an end-to-end methodology into tangible business value requires proving those operational outcomes with evidence. Measuring packaging supplier performance shows procurement teams whether approved standards are maintained across every site.
Procurement teams must look beyond headline statistics, as a single high overall delivery percentage can easily mask recurring regional defects or hidden quality gaps.
Instead, procurement teams should track trends in the following performance metrics:
- First Time Order Fulfilment (FTOF): Measures how much of an order is supplied correctly the first time.
- Delivered Service Level (DSL): Measures the proportion of ordered stock that arrives usable, once credits, errors, split invoices and accepted substitutions are accounted for.
- Product Quality (PQ): Measures whether supplied products meet the agreed specification.
- Delivery On Time (DOT): Measures whether deliveries arrive within the agreed delivery window.
Systematic supplier-performance reviews help procurement teams assess whether line yields, quality standards and service levels remain consistent across sites. GM Packaging reports against agreed targets for each of these measures, providing solid evidence rather than vague reassurance.
Questions to Ask Your Packaging Supplier
Supplier selection sets the ceiling on packaging performance for the life of the contract. Asking the right questions before an appointment reduces the risk of quality drift and supply disruption, while providing a clear view of the long-term total cost of ownership:
1. What will our documented packaging specification cover?
Asking this ensures your physical requirements are strictly locked, preventing batch variance across repeat orders. Procurement teams should expect suppliers to provide contractually bound numeric limits for dimensions, material grades and performance tolerances.
2. How will you test the packaging on our equipment before the bulk supply?
This verifies that physical samples actually run smoothly on your automated machinery, eliminating costly post-rollout disruptions. Look for suppliers who mandate pre-supply trials on your actual equipment before approving any volume production.
3. Will you notify and seek approval before any material, tooling or sourcing change?
This directly prevents undocumented specification drift and unauthorised material substitutions. Procurement teams should confirm contractual clauses requiring advance notification and formal sign-off by a named technical approver before any manufacturing changes occur.
4. How will you keep our critical packaging lines supplied?
Continuity planning ensures your multi-site rollouts are protected against seasonal demand spikes and global disruptions. A partner should demonstrate intelligent demand forecasting capabilities, alternative manufacturing sources and dedicated upstream safety stock.
5. Do you report packaging performance trends by site and product?
Headline delivery percentages mask localised defects, so granular tracking is vital for true operational accountability. Teams should expect suppliers to provide transparent, historical performance trendlines broken down clearly by individual account, site and specific SKU.
6. How will yield figures and reject rates be reported?
Tracking these metrics proves how well the packaging actually performs during daily operational use. Look for a supply partner who actively measures and reports on ongoing line yields, reductions in defects and practical runnability over time.
7. What is the process if performance falls below target?
Defining this process guarantees swift, actionable resolution when service levels slip. Request a clearly documented escalation path, complete with root-cause analysis procedures, strict deadlines and named owners responsible for corrective action.
Evaluating suppliers against these operational criteria shifts your procurement focus from simple unit pricing to long-term supply resilience. METHOD 360® is structurally designed to answer these exact questions with verifiable evidence, actively governing your specifications, performance measures and continuity arrangements across every single order.
Build Consistency Into Every Packaging Order
Setting up internal quality controls, chasing paperwork and manually auditing vendors requires significant time and operational overhead. A formal specification lock reduces this administrative burden by defining the approved product requirements contractually and requiring any proposed changes to follow an agreed review and approval process.
Start every order from a specification you can prove.
