Centralizing Private-Label Packaging Across Co-Packers and Stores
NorthLine Grocers operates 140 stores and uses three co-packers for private-label snacks. Over 15 years, store-level buyers have chosen local packaging suppliers; each co-packer buys its own film. A central sourcing team proposes a single national film supplier, saving 9% (about $2.3M annually) and improving print consistency. The catch: all three co-packers must move to one resin specification, share weekly forecasts through a new portal, and accept 6-week order lead times instead of 2. Two co-packers say the spec change will require line trials and may reduce throughput 4%; one store region has a local supplier that also provides emergency same-day service for promotional packaging. The national supplier requires a 3-year contract with 80% volume commitment. The COO supports the savings; the plant managers and regional merchandising team are resistant. The initiative is 90 days from the first planned conversion.
1. How should the sourcing team sequence implementation across the co-packers and stores? Justify the sequence.
Read the worked answer
Sequence by risk, not by savings. Convert one co-packer first - the one with the most stable volume and least promotional complexity - and run line trials before any store conversion. Use three gates: specification and trial approval, one-region conversion, then scale. A simultaneous conversion risks a 4% throughput loss across all three co-packers at once, which could create a supply gap.
Protect service during transition. Keep the local same-day supplier as a formal exception with a spend cap and a defined trigger (promotional packaging needed inside 48 hours). Do not force emergency service through the national supplier before its lead time and service levels are proven.
Phase the volume commitment. The 80% commitment should apply to addressable volume after documented exceptions and should ramp over 12 months. Committing all volume on day one gives away leverage and may leave NorthLine paying for volume it cannot route. The first region becomes the proof point for throughput, lead time, and print quality; savings follow evidence, not the calendar.
2. How would you handle the maverick/local spend and the emergency-service requirement in the contract design?
Read the worked answer
Separate maverick spend from legitimate exception. The same-day promotional service is a service-level requirement, not disloyalty. Carve it out in the national contract: allow local spot buys for orders inside 48 hours or below a defined dollar threshold, capped at, say, 5% of addressable spend. Publish the cap and track it.
Make compliance easy. Provide a national catalog, pre-approved items, and a one-step exception process. Track compliance by store and co-packer and review it monthly. Tie part of the co-packer's commercial terms to forecast accuracy and spec compliance rather than blind volume.
Redesign the commitment. Change 80% to 80% of addressable volume after documented exceptions, with a rebate if actual volume exceeds the commitment. This protects the supplier's economics without pretending that emergency service does not exist. Forcing 100% compliance either fails or creates hidden costs and service risk; a defined exception is cheaper and more honest.
3. What cross-boundary governance would you set up with the co-packers to make the forecast-sharing and spec change work?
Read the worked answer
Build a joint business plan, not a portal. The co-packers bear the trial cost and throughput risk, so governance must allocate cost and risk, not just share data. Create a change control board with one representative from each co-packer, supply management, quality, and merchandising. Any resin or specification change goes through it with a cost/benefit and a conversion timeline.
Align incentives. Fund line trials and any throughput loss through a one-time conversion allowance or a gain-share on the 9% savings. Without compensation, co-packers will resist or slow-walk the change even if they sign the contract.
Measure the boundary. Use joint KPIs: forecast accuracy (MAPE), order lead-time adherence, throughput, scrap, and service. Start with weekly operations reviews for 90 days, then monthly. Use a data-sharing agreement with clear definitions and restrictions on competitive use. The savings are created at the co-packer line, not in the national contract; governance has to reach that far.
