supply chain blockchain consulting Case Study Template: Traceability KPIs That Execs Accept

Why exec‑grade KPIs look different in 2025

If you’re still focused on things like “how many suppliers you’ve onboarded” or “blockchain transactions per second,” you might be missing the bigger picture that regulators and customers want to know. They’re asking questions like: Can you show the product's origin in just hours, instead of weeks? Can you deliver EPCIS events and verifiable credentials that customs and market surveillance can check automatically? Is your Digital Product Passport or Battery Passport data complete and easy to query? These are the real deal--auditable, externally referenced outcomes--not just fancy metrics to brag about. (fda.gov)

Below, you’ll find a straightforward case study template that we use at 7Block Labs. It’s designed to be quick and easy for executives, complete with KPIs and target ranges, and it’s all in line with the latest rules and standards.

Case Study Template: Blockchain Traceability That Survives Audit

Feel free to use this structure for your internal presentation or public case study. Just swap out the bracketed text with details specific to your client.

1) Company snapshot

• Industry and scope: [like, exporting cocoa grinders to the EU; covering 3 regions; around 1.2k suppliers]
• Risk drivers: [for instance, EUDR origin proof; exposure to UFLPA cotton; FSMA 204 for fresh-cut fruits]
• Systems landscape: [ERP = SAP S/4; WMS = Blue Yonder; MES = Ignition; using 2D barcodes at the packhouse; some limited RFID]

2) Regulatory clocks and scope

• EU Deforestation Regulation (EUDR): Here's the scoop: big operators need to be on board by December 30, 2026, while micro and small operators get a bit more time, with a deadline of June 30, 2027. Don’t forget that all due diligence statements must include the geolocation of the plots--whether that’s a point or a polygon, depending on what’s needed. (reuters.com)
• EU Battery Passport (Reg. 2023/1542): Starting February 18, 2027, there’s going to be a must-have battery passport for electric vehicles, industrial batteries over 2kWh, and light mobility transport batteries. Keep an eye on this one! (eur-lex.europa.eu)
• FSMA 204: The original compliance date was set for January 20, 2026, but the FDA is thinking about giving us a breather with a proposed 30-month extension, pushing it to July 20, 2028. Either way, it’s important to have a plan in place to respond to trace requests within 24 hours. (fda.gov)
• DSCSA (U.S. pharma): There’s an “enhanced system” for electronic and interoperable package-level tracing coming up. Some obligations will be stretched into 2025-2026, like for dispensers with 26 or more full-time employees--they'll have until November 27, 2025, while smaller dispensers will need to comply by November 27, 2026. (fda.gov)

3) Standards and architecture (auditor‑friendly)

• Data Layer: We're diving into GS1 EPCIS 2.0 for sharing events with a bunch of cool tech like JSON‑LD and REST, plus sensor data and certifications. Don't forget about GS1 Digital Link/2D codes at the item and case level. Check it out here: (gs1.org)
• Identity and Attestations: For identity, we’ve got W3C Verifiable Credentials (VC 2.0) along with Decentralized Identifiers (DID) that are perfect for trade, compliance, and proving origin. The best part? These are now W3C Recommendations! More info right here: (w3.org)
• Ledger: We’re using a permissioned L1 ledger, like Hyperledger Fabric 2.5 LTS, to secure hashes, proofs, and check credential status. Plus, we can use channels for privacy among partners and even purge private data when needed. Learn more at: (hyperledger-fabric.readthedocs.io)
• External Verifiers: Customs pilots and GBI identifiers (GLN/LEI/DUNS/Altana ID) show us where automated checks are headed, and we're designing to feed into these systems. Get the scoop here: (cbp.gov)

4) What we implemented (example)

• Capture: Handle those 2D barcode scans for items-to-cases, plus keep tabs on the inbound and outbound EPCIS events, which include Object, Aggregation, and Transformation. Check it out on gs1.org.
• Proofs: We’re talking about a Merkle-root hash for the daily EPCIS event batch stored on the consortium ledger. You can also issue VCs for things like origin, certifications, and chain-of-custody links.
• Resolution: Use GS1 Digital Link resolver endpoints to provide links for regulators and partners (think traceability, recall status, and certificates), all mapped from GTIN and SSCC. More details at gs1.org.
• Integration: Get those event brokers and APIs working with your ERP/WMS; set up credential verification services; and don’t forget about your evidence vault!

5) Baseline vs. target (fill with your numbers)

• Baseline: Time to trace a farm or batch: [around 3-7 days]; event coverage is about [~40%]; KDE completeness is currently [partial].
• Targets: Check out the KPI catalog below.

KPI Catalog Execs Accept (with target ranges)

Setting KPI Targets: Go with Regulations and Customer SLAs

When you're setting those all-important KPI targets, focus on regulations and customer Service Level Agreements (SLAs) instead of just what the tools can do. Think of these as your starting point, but don't forget to tweak them based on the specific risks and industry you're dealing with.

1) Time‑to‑Trace (TtT) to Origin, p95

Definition: This is the time it takes to track an incident ID (like a lot or serial number in the market) back to a verified chain-of-custody all the way to the farm, batch, or provider.

Targets:

• For consumer goods and food: aim for p95 to be ≤ 2 hours and p99 to be ≤ 8 hours. This actually beats the FSMA 204 standard of a 24-hour response time. (fda.gov)
• If you're looking for a retail best-practice benchmark, check out how Walmart’s blockchain pilots managed to reduce mango traceback from about 7 days to just seconds. So, why not set your goal to be in the minutes range, instead of days? (wired.com)

2) EPCIS Event Capture Coverage (ECC)

Definition: This measures how many of our physical movements and transformations are shown as compliant EPCIS events across Object, Aggregation, and Transformation.
Targets:

• We’re aiming for over 98% for Object/Aggregation on our key SKUs and more than 95% for Transformation where it makes sense (like with recipes and blending). Check out more details here.

3) Data Latency SLA (Capture‑to‑Query)

Definition: This measures the median and p95 time it takes from when an event is captured to when it's queryable within the ecosystem.
Targets:

• Aim for a median of ≤ 60 seconds; for recall-relevant events, keep p95 at ≤ 5 minutes.

4) KDE/CTE Compliance Rate (FSMA 204)

Definition: This metric reflects the percentage of shipments on the Food Traceability List that have all the Key Data Elements filled out for every Critical Tracking Event.
Targets:

• Aim for 100% completeness; let’s try to get the response pack to the FDA in less than 4 hours, even though the rule gives us 24 hours to do so. (fda.gov)

5) EUDR Geolocation Completeness and Validity

Definition: This measures the percentage of consignments that have valid geolocation info for all the originating plots. It’s got to have the right geometry type (point vs polygon), be in WGS84 format, and fit within the proper production date range.

Targets:

• Aim for 100% of consignments in scope; use polygons for plots larger than 4 hectares; and make sure due diligence statements are ready to submit by the application date. (eur-lex.europa.eu)

6) Digital Product Passport / Battery Passport Readiness

Definition:

This measures the percentage of SKUs in the impacted categories that have a passport with all the necessary attributes and role-based access sorted out.

Targets:

• Battery categories: We're aiming for 100% readiness by Q4 2026, gearing up for a go-live on February 18, 2027. You can check out the details here.
• For ESPR-DPP categories (like textiles and more), we need to align the data model between 2026 and 2028 according to the Commission's working plan. We'll also be showing off some working prototypes and preparing for registry integration. More info can be found here.

7) Credentialed Chain‑of‑Custody Rate (CCoC)

Definition: This is the percentage of shipments that have at least one verifiable credential (VC 2.0) from every upstream custodian. These credentials are neatly cryptographically linked to identifiers like GLN/LEI and EPCIS event hashes.
Targets:

• We’re aiming for over 95% in high-risk lanes by the end of the pilot and hitting that sweet spot of 100% before we go live with production. The demos from CBP are paving the way for some cool automated verification at the borders. Check it out here: (w3.org)

8) Scan Success Rate for Next‑Gen Barcodes

Definition: This refers to how often scans at the point of sale (POS) or during receiving succeed when using GS1 2D barcodes, like QR codes with GS1 Digital Links or GS1 DataMatrix.

Targets:

• We’re aiming for over 99% success in controlled receiving and more than 97% in POS pilot programs. Let's gear up for that “Sunrise 2027” goal to keep everything on track and dodge any relabeling hassles down the line. You can find more about it here.

9) Supplier Onboarding Lead Time (SOLT)

Definition: This is basically the average time it takes to get a new supplier onboard so they can start producing signed events and VCs.
Targets:

• For “standard” suppliers, we’re aiming for less than 15 working days; and for low-risk traders (where we can reuse GLN/LEI and templates), we’re shooting for under 5 days. (cbp.gov)

10) Cryptographic Evidence Coverage (CEC)

Definition: This is the percentage of traceability records where we can prove the integrity using an on-chain hash or a credential signature (that’s the Merkle root plus the VC signature).

Targets:

• We’re aiming for over 99% for regulated lots and more than 95% across all SKUs.

11) Audit Readiness SLA

Definition: This is all about how quickly we can whip up a top-notch evidence pack for regulators, including EPCIS events, VCs, resolver links, and standard IDs.

Targets:

• Less than 2 hours for FSMA 204
• Less than 24 hours for customs reviews
• Less than 7 days for full third-party audits

You can check out more details on fda.gov.

12) Recall Scope Reduction

Definition: This measures how much we can shrink the number of units recalled by using precision trace compared to just saying “all lots possibly affected.”

Targets:

• We’re aiming for a reduction of at least 60% once our event/credential coverage hits over 95%. This goal aligns with the quick pinpointing we saw in those early retail pilots. (wired.com)

Data model and interfaces you’ll be judged on

• EPCIS 2.0 JSON‑LD with CBV: This is all about capturing those essential Object, Aggregation, Transformation, and Transaction events. Plus, it includes sensor extensions specifically for cold chain management and mixing/batching transformations. You’ll find REST capture and query endpoints handy! (gs1.org)
• GS1 Digital Link: Imagine having one barcode that does it all--serving as a link for POS, consumers, and regulators with different link types like gs1:traceability and gs1:jws for digital signatures. And the best part? You can keep those links updated without needing to repackage anything. Just make sure to use conformant resolvers! (gs1.org)
• Verifiable Credentials 2.0 + DIDs: This is where you can issue credentials for things like origin, custody, certification, and those important facility identifiers like GLN/LEI. It’s a great way to align with CBP’s interoperability push to reduce the risk of border holds. (w3.org)
• Ledger strategy: Here’s a solid plan--anchor your daily batches (think Merkle roots) and credential status lists to a permissioned chain, like Fabric 2.5 LTS. Don't forget about using private data collections, channel-level privacy, and the PurgePrivateData API for those necessary deletions while still keeping those immutable hashes intact. (hyperledger-fabric.readthedocs.io)

Worked examples by regulation

A) EUDR for cocoa/coffee: from polygons to credentials

• What to Store: For each consignment, make sure you keep track of the plot geolocations (whether it's a point or polygon, depending on what you need), the production date range, and the chain of custody leading to the EU operator. Don't forget to include these details in your Due Diligence Statement. (eur-lex.europa.eu)
• KPIs to Publish:
  • Geolocation completeness: Aim for 100% of consignments.
  • Polygon validity (self-intersection test, WGS84): Ensure 100% pass the pre-submission validation.
  • Time-to-DDS assembly: Keep it under 4 hours from the moment of request.
• Implementation Notes: Consider using a field app that captures WGS84 coordinates and relevant metadata, then generates a Verifiable Credential (VC) for “Geolocation Assertion,” signed by an accredited collector. Make sure to hash the GeoJSON to maintain its integrity.
• Evidence: Keep a resolver link from the GS1 Digital Link to a regulator-view endpoint, which should only expose the DDS and a limited EPCIS chain (based on roles). (gs1.org)

B) FSMA 204 for FTL foods

• What to store: You'll want to keep track of KDEs for each CTE, such as shipping, receiving, and transformation, along with a solid traceability plan. Make sure to respond to any FDA data requests within 24 hours; aim for hours as your KPI goal, not days. Check out more details here.
• KPIs to publish:
  • KDE completeness: Shoot for 100% on FTL items.
  • Time to Transformation (TtT) p95 should be ≤ 2 hours; for p99, it’s ≤ 8 hours.
  • Keep your audit readiness pack SLA under 2 hours.
• Implementation notes: The EPCIS TransformationEvents link ingredients to outputs, while VCs hold onto supplier identity proofs. Plus, there’s a dashboard that can whip up FDA-friendly CSV/JSON packs whenever you need them. More info can be found here.

C) EU Battery Passport (by Feb 18, 2027)

• What to store: You'll want to keep the passport with all the model-level and unit-level data outlined in Annex XIII. Make sure to set up role-based access subsets, whether that’s for the public or authorized users. Plus, design a resolver endpoint that can be accessed via a 2D code on the pack. Check out more details here.
• KPIs to publish:
  • Aim for 100% passport completeness for in-scope batteries by Q4 2026.
  • Keep the median resolver response time under 300 ms and ensure uptime exceeds 99.9%.
• Implementation notes: Use EPCIS for tracking custody and sensor data like temperature and state of health (SoH) logs, and make sure to link this back to the passport record. Don’t forget to hash snapshots to the ledger on a monthly basis. You can find more info about EPCIS here.

D) DSCSA enhanced tracing (U.S. pharma)

• What to store: Make sure to keep track of package-level traceability and verification with electronic exchanges. It’s super important to grasp the stabilization and exemption timelines stretching through 2025-2026. You can find more details here.
• KPIs to publish:
  • Package-level trace coverage: Aim for 100% for all Rx items that are in scope.
  • Verification response SLA: Keep it under 60 seconds for any suspect product queries.
  • Dispenser readiness: Stick to the category dates (≥26 FTEs by 2025; small dispensers by 2026). You can dive into more specifics here.
• Implementation notes: The EPCIS 2.0 JSON-LD format suits the DSCSA interoperable exchange perfectly. Plus, don’t forget to include VC attestation for your authorized trading partner status. This will help cut down on those tedious manual checks. Find further info here.

Emerging practices that are sticking in audits

• VC‑first evidence: More and more customs and market surveillance pilots are jumping on the W3C VCs bandwagon for trade documents. So, when you're putting together your “evidence pack,” think of it as a collection of verifiable credentials with deterministic hashes that align with your EPCIS event batches. Check it out here.
• GBI identifiers: Don’t hesitate to ask your suppliers for their GLN/LEI right off the bat. This not only minimizes the “unknown party” risk but also meshes well with CBP’s direction on Global Business Identifier Testing. More info can be found here.
• Resolver governance: Make sure to expose those regulator-only link types (think traceability, certifications, recall status) through GS1 Digital Link resolvers, while keeping the public content distinct. Regulators appreciate a quick scan that leads to the right information. Learn more about this here.
• Next‑gen barcodes: Start piloting GS1 2D scanning now! The industry is really gearing up for widespread adoption by 2027, so getting some early wins under your belt will help you avoid having to redo things later on. For more details, click here.
• Private data purging: If you’re working in markets where privacy is a big deal, consider using Fabric’s PurgePrivateData feature to take out any PII from your peers while still keeping that crucial immutable evidence on the blockchain. Dive into the specifics here.

ROI math your CFO won’t argue with

• Recall scope reduction: Imagine a “blanket recall” that includes 10 million units. With a boost in precision by 60%, you could save 6 million units at [unit COGS], which usually covers the program costs for that single incident. Early retail pilots have shown that faster traceability can really sharpen the focus on what needs to be recalled. (wired.com)
• Compliance cost avoidance: If you miss out on EUDR geolocation or are slow with FSMA responses, it can lead to detentions and market losses. Getting on board with GLN/LEI and VC exchange can make border clearance a breeze (just check out the CBP demos). (cbp.gov)
• Working capital: Keeping an eye on real-time events means you can cut down on safety stock. Typically, you can see a 1-2% reduction in inventory at scale, which helps balance out those running costs.

Implementation playbook (12 weeks to first audit‑safe lane)

Weeks 0-2: Scope and Data Mapping

• Let's start by mapping each SKU and lane to the relevant regulations and standards. Choose the right identifiers like GTIN/SSCC and GLN/LEI. Don't forget to define those EPCIS event points and Critical Tracking Events (CTEs). You can check out more details here.

Weeks 3-6: Instrumentation and Schemas

• Turn on 2D barcodes and/or RFID wherever it makes sense financially; set up EPCIS capture (Object/Aggregation/Transformation); establish resolver endpoints and linkTypes; get the VC issuer/verifier up and running. (gs1.org)

Weeks 7-9: Credentials and Ledger Anchoring

• Get those origin and custody credentials sorted out; make sure to anchor daily hashes to a permissioned ledger; integrate GLN/LEI into the supplier master. Check out more details here.

Weeks 10-12: Dry-run audits and KPI hardening

• Create those FDA/EU evidence packs.
• Aim for TtT to be 2 hours or less.
• Make sure we validate EUDR geolocation and assemble DDS correctly.
• Wrap up the dashboards!

FAQ for decision‑makers

• Do we really need blockchain if EPCIS is already around?
  EPCIS does a great job of standardizing event data, but blockchain takes it a step further by providing independently verifiable integrity through hash anchors and a decentralized status for credentials. Auditors are now looking for both: data that’s easy to understand and cryptographic proof they can rely on. (gs1.org)
• Which chain?
  Go for a permissioned ledger that prioritizes enterprise privacy, like Fabric 2.5 LTS. It's a good idea to keep your payloads off-chain and only store hashes and credential statuses. You can use private data collections and make sure to purge them when necessary. Check out more details here!

How do we handle DPP/Battery Passport uncertainty?

To reduce the risks, we should sync up with the Commission’s working plan schedule and use a schema that can be tailored for different roles. Keep in mind that the battery deadlines are set in stone (February 18, 2027), so think of that as your solid anchor while you prototype the DPP along the same lines. You can check out the details here.
