Let‘s get started.

The Scale and Complexity of Modern Supply Networks

Global trade has exploded over the past decades as businesses source materials, produce and deliver products using interconnected supply chains spanning across continents. Coordinating these vast, intricate networks handling massive product and data flows has become extremely complex.

To add to this complexity, consumers now expect fully customized and timely deliveries across channels while investors demand better supply chain risk management and working capital optimization.

However, existing supply chain systems have failed to catch up to match these expanding demands. Some key pain areas include:

Lack of end-to-end visibility – Multiple fragmented systems across functions like order taking, manufacturing, storage and transport lead to inventory and shipment visibility gaps that impact planning and forecasting.

Inefficient processes – Manual paperwork slows down supply chain execution while increasing costs and errors. This includes purchase orders, customs clearance, freight invoices etc.

Low trust – Absence of transparency coupled with limited traceability encourages supplier frauds, grey market trading, counterfeit production etc. that remain hidden.

Poor product continuity – Inability to instantly trace faulty batches during recalls leads to delayed action, destroying customer trust and brand reputation.

Revenue Leakages – Invoice and payment reconciliation gaps due to errors, duplication or fraudulent transactions causes millions in revenue leakages each year.

Blockchain technology has now emerged as a silver bullet – with its decentralized, immutable and transparent shared ledger capabilities able to target these enduring supply chain problems.

Decoding Blockchain: A Primer

Simply put, blockchain enables transmission and storage of data securely over a permissioned, peer-to-peer network without requiring a central controlling authority. Some of its standout capabilities include:

Decentralized Ledger – The distributed ledger exists immutably across the blockchain network, removing risks associated with a single point of control.

Consensus Validation – Any updates to the ledger are cryptographically validated by network participants using agreed protocols like proof-of-work and proof-of-stake. This ensures trust.

Provenance Tracking – Detailed historical logs enable tracing movement of assets providing pedigree and improving accountability.

Smart Contract Automation – Programmed business rules and workflows self-execute when meeting pre-defined conditions enabling process streamlining.

Oracles – These real-world data feeds securely supply information from external systems to trigger smart contract execution, enabling automation.

These differentiating aspects integrate to provide a shared single source of truth all parties can rely on for transparent and timely decision making.

Unlocking Transformational Value Across Supply Chains

“Blockchain has the potential to transform supply chains in every sector and industry with transparency, speed, security and savings.” – Kari Korhonen, Vice President, Supply Chain Operations, Philips

When leveraged creatively, blockchain provides a frictionless layer for systems integration and process coordination across supply chain functions and partners. Key areas that can be enhanced include:

Asset Tracking – Assigning unique digital IDs to parts, ingredients and products enables continuous tracking from manufacture through distribution into after-sales service.

Order Visibility – Order details, shipment locations and inventory status shared between suppliers, vendors, 3PLs and customers improves planning and delivery.

Logistics Coordination – Linking transport, warehouses, ports/airports and customs via smart contracts triggers instant information sharing for faster releases and payments.

Transaction Management – Invoicing, payments, financing, tax filings etc. can be streamlined by integrating delivery acknowledgements and immutable audit trails.

Regulatory Compliance – Certificate authenticity verification, intellectual property monitoring, mandatory reporting and taxes filings can leverage blockchain infrastructure.

Exception Handling – Tracking expiries, handling recalls and returns, managing trade promotions, analyzing failures etc. benefit from data transparency.

Jointly, these applications target the biggest supply chain weaknesses around trust, transparency, security, autonomy and efficiency at scale.

Industries Adopting Blockchain to Overhaul Supply Operations

Early adopters from diverse sectors are already using blockchain to minimize endemic supply chain problems, optimize working capital needs and build future-ready value chains:

Automotive – Volkswagen uses blockchain to trace cobalt coming into its electric vehicle factories while Toyota is tracking parts across its manufacturing ecosystem using DLT. These provide evidence for sustainability compliance.

Aviation – Accenture collaborated with Airbus for developing a blockchain-based platform Skytoken that helps airlines prevent cargo damage while tracking components for MRO transparency.

Electronics – Foxconn employs blockchain for monitoring supply inventories, dealing with trade promotions and managing device warranty repairs across a globally dispersed supplier base.

Oil and Gas – Chevron has partnered with commodity traders like Total and Reliance to launch a blockchain platform Vakt for handling cumbersome, paper-heavy cargo post-trade executions.

Retail – Walmart uses blockchain ledger to record supplier details, inspection certificates, logistics events and temperatures for farm produce like leafy greens to enhance safety, quality and extend shelf life.

Pharmaceutical – Novartis has created a blockchain to address counterfeit drugs entering the supply chain while optimizing field inventory distribution to dispensaries on time.

These early initiatives have delivered promising results – like enhanced traceability up to 70%, cost reductions by 15-30% and cycle time improvement in the range of 30-50%.

Hurdles to Address in Mainstream Blockchain Adoption

Despite proven benefits from pilots, hurdles remain in deploying blockchain at enterprise scale. These include:

Consortium Creation – Co-opetition paradox exists with competitors not wanting to directly transact on the same blockchain network, especially if designed to strategically benefit certain dominant players. Governance protocols must equitably balance control.

Legacy Integration – Centralized ERP, WMS and TMS systems still dominate enterprise IT landscapes, making integration cumbersome. Lack of interoperability standards also creates vendor lock-in risks in the still emerging blockchain tech space.

Unclear Data Regulations – Determining exact compliance criteria is tricky with regional variability in trade, tax, ownership, IP protection and contract enforceability laws. Jurisdiction complexities have legal teams concerned.

Cryptocurrency Risks – Volatility and perceived speculation means wider finance teams aren’t fully bought into transacting business solely in cryptocurrency denominated platforms.

Talent Shortage – Business heads eager to capitalize on blockchain must deal with a severe skills shortage as developer communities are still coming up the learning curve, limiting solution creation opportunities.

These concerns can make the CFO apprehensive about allocating capital to experimental blockchain projects where ROI metrics seem fuzzy. However, these deterrents are increasingly getting addressed through better design, standards and accelerators.

Best Practices for Ensuring Successful Blockchain Deployments

Supply chain leaders keen on capitalizing early on blockchain’s transformational potential must follow disciplined approaches:

Start Small, Demonstrate Value – Instead of boiling the ocean, identify contained environments handling high-value goods or expensive trade corridors ripe for initial pilots.

Acquire Executive Sponsorship – Educate leadership early on tangible metrics around yield, velocity and compliance. Assign cross-functional teams and immunize them to fine-tune solutions.

Invest in Capability Building – Develop talent pools through vendor partnerships, in-house training and global expert networks to address specialized skills needed in cryptology, systems integration and user experience design.

Set Clear Milestones and Metrics – Customize performance indicators spanning process improvement, trading relationship enhancement and working capital optimization. Align to business objectives.

Utilize Managed Services – To accelerate time-to-value, leverage configurable software-as-a-service solutions combining DLT with adjacent technologies like IoT, AI and advanced analytics.
