Vision & Mission

Vision

Revolutionizing the Global Supply Chain Ecosystem with Integrated, Proactive Data Sharing and Collaboration

The introduction of the Predictive Unit Real-Time Information Service (PURIS) enriches a company's resilience strategy through standardized data sharing, giving stakeholders heightened transparency and comprehensive information. This clarity allows PURIS users to detect supply chain issues earlier, initiate solution-finding more swiftly, and access a wider array of options, leading to more effective, cost-efficient, and environmentally friendly outcomes. By facilitating proactive anticipation, concurrent management, and reactive recovery, PURIS supports the supply chain across pre-, during-, and post-disruption phases, thereby improving operational efficiency and resilience within the Catena-X network.

Mission

Empowering Stakeholders with Real-time, Predictive Insights for Proactive Supply Chain Management

The PURIS KIT provides the necessary standards, aspect models, interfaces, logics, and processes to implement a comprehensive and compliant exchange of short term supply chain key information between business partners. It intends to enhance the foundation of supply chain interactions, encouraging a proactive management approach over a reactive one.

The core is the exchange of supply chain key information between partners within a horizon of up to four weeks, including:

1. Item Stock: Visibility of current inventory levels on both sides
2. Short-term Material Demand: Forecast of materials needed for production
3. Planned Production Output: Anticipated production output quantities
4. Delivery Information: Scheduled and actual deliveries and their details
5. Days of Supply: Information on how long the inventory on hand will last

With PURIS, supply chain partners can anticipate, adapt, and align their operations to both current and future events, optimizing inventory levels, production and planning capabilities. The result is improved operational efficiency, enabling businesses to respond adequate and quickly to changes and disruptions in the supply chain.

The PURIS service enriches companies' resilience strategy by improving data sharing and providing key information between supply chain partners on demand. This enables users to identify and manage supply chain issues with enlarged foresight. The result is that (from a process perspective) downstream services, systems or applications can detect critical bottlenecks at an earlier stage.

Key aspects of PURIS are:

• Standardized information exchange: Base for a fast and effective handling of shortages and enhances early detection capabilities for optimized supply chain decision-making.
• Short-term focus: PURIS targets a period of 0-4 weeks, although longer periods are not technically restricted.
• Collaborative approach: Equal and fair data exchange (quid-pro-quo) between partners (1-up / 1-down), leading to a more transparent, predictable, and resilient supply chain ecosystem.
• Data usage control and compliance: PURIS employs the Catena-X data space to ensure the required level of data security and sovereignty for all participants.
• Accessibility: PURIS provides a FOSS (Free and Open-Source Software) reference implementation that aims to keep the entry threshold for participating in PURIS as low as possible, making it easier for smaller businesses to participate and take advantage of the benefits.

By considering these principles, PURIS is not just enhancing current supply chain management practices but is also paving the way for a more agile, informed, and responsive automotive industry

Today's Challenge

Supply chain complexity and the frequency of crises and exceptional situations pose a growing threat of significant disruptions, supply shortages and even temporary production halts for both small and medium enterprises (SMEs) and large enterprises (LEs). Rapid response and replanning are critical, which can involve considerable expenses. Costly, drawn-out decision-making among partners who might be reluctant to share information can lead to expensive special arrangements and workarounds. The longer the problem persists, the fewer viable alternatives for ensuring a continuous supply. There is an urgent need for a better information base for decision-making.

Status-quo:

1. Supply Chain Transparency: The lack of up-to-date data and transparency in the supply chain makes it difficult to anticipate disruptions and actual demand, manage production and inventory efficiently, and ensure timely deliveries. Complex and Volatile Supplier Network: The supply chain, with its widespread and diverse suppliers, faces visibility and control challenges. Demand volatility, influenced by key companies, impacts forecasting and immediate needs.
2. Inefficient communication: Manual and non-standardized information exchange, e.g. via Excel or phone, between partners is slow and can lead to misunderstandings, errors and unnecessary effort, which in turn negatively impacts the supply situation and increases costs.
3. Lack of Trust: Reluctance to share sensitive information, such as inventory levels, demand forecasts, and production capacities hinders the flow of critical information and prevent the formation of a cohesive, collaborative supply chain network. This can lead to a siloed and inefficient supply chain, where the best and most sustainable solutions are not realized. Consequences are missed opportunities, increased costs, and decreased competitiveness.

Moreover, currently only proprietary systems are available, which are insufficiently scalable and also involve a vendor lock-in. This highlights the need for an open standard and a FOSS (Free and Open Source Software) reference implementation. Moreover, these systems often have a long-term focus on demand and capacity management.

Business Value

The traditional approach to managing supply chains is often inflexible and involves a high degree of manual work, leading to delays and limited opportunities for proactive measures. This is particularly challenging when dealing with potential shortages that can affect the entire supply chain.

PURIS transforms this by creating a collaborative network within the Catena-X data space, where partners, including suppliers and customers, share and use daily data. This approach allows for a dynamic and interconnected supply chain management, enhancing the ability to monitor supply and demand, identify potential issues early, and make informed decisions.

The benefits of adopting the PURIS KIT for suppliers and customers include:

Improved Efficiency and Data Quality:

• Less manual information gathering through automated exchange of required supply chain information.
• Higher data quality and reliability through the use of standardized plan and actual data.
• Efficient planning by having a broader information and decision base.

Better Visibility and Collaboration:

• Shared view of the supply and demand situation between partners; especially in tight supply situations.
• Data sovereignty through the usage of Catena-X standards and principles as a base for trustful cooperation.

Cost Reduction and Sustainability:

• Reduced costs through avoidance of downtime, production holds and overstocks.
• Contribute to waste reduction, lower emissions, and compliance with environmental regulations and sustainability goals by avoiding unnecessary logistics measures, such as underutilized transportation of small quantities.

Overall, adapting PURIS helps businesses achieve operational excellence, strategic resilience, data-driven decision making, collaborative innovation, and sustainability, all while reducing costs and improving market responsiveness.

Benefits for Large Enterprises, Small and Medium-sized Enterprises, and Solution Provider:

• For OEMs and large suppliers:
  • Increased overall supply chain efficiency: When a critical mass of participants is reached, the PURIS standard can increase efficiency of the entire supply chain, ultimately benefiting OEMs and large Tier-1s at the end of the chain.
  • Lower operating and maintenance costs: Consolidating and standardizing data flow through the PUris standard can reduce operating and maintenance costs for proprietary systems.
  • Avoid vendor lock-in: With the PURIS standard, there is no need to depend on a dominant solutions provider that can result in vendor lock-in.
• For Small and Medium-sized Enterprises (SMEs):
  • Single integration point: With PURIS there is just a single integration point, reducing the complexity and costs of managing and serving multiple customer interfaces, systems and platforms.
  • Bi-directional data exchange: One of the significant benefits of PURIS is that it enables small and medium companies to receive information in addition to providing it. This bi-directional data exchange on equal footing reduces blind decision-making and guesswork, allowing for more informed decision-making and collaboration
  • Competitive advantage: Using the PURIS standard can give a competitive advantage when bidding for contracts, as compliance with the PURIS standard can be favored in some procurement processes. By adopting the PURIS standard, it can be demonstrated to potential partners that a SME ist committed to data exchange best practices, making it a more attractive partner for collaboration and contract opportunities.
• For Solution Providers:
  • Scaling solutions: Solution providers can scale their PURIS solutions in the market and thereby access new customer groups.
  • Versatile business models: Offerings in the areas of consulting, integration, and operation allow for various business models, providing solution providers with the flexibility to tailor their services to specific customer needs.
