This is harmful not only to the environment but also has adverse effects on the population of the area where the minerals are mined disturbing the triple bottom line of sustainability. Through this paper, we propose a holistic approach to tackle the problem by not only using technology but also including systematic input from different stakeholders through the lifecycle. We, thus, combine principles from participatory modelling and blockchain technology to bring transparency and accountability in the process. This approach is a step-by-step guideline for including circularity and sustainability through a continuous process of input collection from real life and validation in the real world thereby resulting in a practical and technologically adept solution yielding better results when compared to a solution developed in an isolated laboratory environment.

Its potential lies in optimising existing business models and creating innovative ones based on various technologies, making them fit for the future by reducing greenhouse gas emissions and fulfilling future decarbonization goals. In order to ensure a successful digital transformation towards decarbonization, managers have to assess the capabilities of their organisation and competently oversee their journey by defining a clear path employing digital maturity models. For this purpose, the analysis focused on published literature concerning digital maturity models developed to guide organisations in navigating their digital transformation journey. A systematic literature review of 36 selected digital maturity models is presented in this paper. These models overlook decarbonisation measures and focus solely on demonstrating digital capabilities, efficiency and profit growth. Therefore, a maturity model for digital decarbonization encompassing dimensions of decarbonization goals, business model innovation, customers and suppliers, products and services, employees, collaboration, processes and activities, data, and IT-infrastructure, -security and -technology has been developed. It assists organisations in reducing their carbon footprint by strategically and effectively leveraging digital technologies. The proposed model has five maturity levels: assess and align, engage and refine, innovate and collaborate, optimize and personalize, and transform and decarbonize.

On the one hand, they deal with issues related to data transparency, traceability, and security in constant back-and-forth communication exchange between customers and sub-contractors having to confirm the order status. On the other hand, there are significant obstacles when it comes to integrating their traditional order management systems with the partner organization's information systems within the production network. These complexities tend to decrease the ability of OEMs to remain flexible and profitable. Therefore, they are constantly looking for feasible solutions to overcome these issues and improve their order management processes. To this aim, this work proposes a novel blockchain-based conceptual framework for order management that intends to establish a secure environment for efficient communication and data integrity. The decentralized and immutable nature of blockchain makes it capable of providing real-time data as well as ensuring data security and transparency. Furthermore, this work also set up basic level SQLite3 databases and design prototypical on-chain and off-chain smart contract logics that can be used to automate various operations and decisions making in order management, thereby, improving the overall order processing efficiency.

Die h{\"a}ufigsten Herausforderungen sind demnach die Ressourcenverf{\"u}gbarkeit, lange Lieferzeiten, der Fachkr{\"a}ftemangel und preisgetriebene Themen. Experten wurden zu aktuellen Ereignissen befragt, wie Rohstoffpreisschwankungen, der Zero-Covid-Strategie von China und Knappheiten in der Logistik. Preisschwankungen betrafen die meisten Unternehmen, w{\"a}hrend Krieg und Sanktionen nur indirekt wirkten. Die Zero-Covid-Strategie f{\"u}hrte zu Vertrauensverlust in China und Knappheiten in der Logistik zu h{\"o}heren Transportkosten. Der Fachkr{\"a}ftemangel wurde auch als aktuelles Ereignis genannt. ▪ Der zweite Themenkomplex ist Ver{\"a}nderungen im SCM gewidmet. Dabei wurde insbesondere der Wandel in komplexere Netzwerke, der Aufstieg des E-Commerce und die Bedeutung von Vertrauen und Transparenz angef{\"u}hrt als wesentliche Ver{\"a}nderungen. Supply Chains sind gewachsen und komplexer geworden, aber auch die Qualit{\"a}t der Vernetzung hat sich verbessert. E-Commerce f{\"u}r Standardprodukte wird weiter an Relevanz gewinnen. Kein Trend zur Deglobalisierung wurde festgestellt. Die Experten sind sich einig, dass Supply Chains "too lean" geworden sind und das Risikomanagement wichtiger ist. Das oberste Ziel sollte sein, die Produktion und Lieferf{\"a}higkeit sicherzustellen. ▪ Der dritte Themenkomplex befasst sich mit Nachhaltigkeit, einschließlich des Lieferkettengesetzes (LkSG), Dekarbonisierung und Nachhaltigkeitsnachweisen. Die meisten Unternehmen erf{\"u}llen die Anforderungen des LkSG und nehmen das Gesetz als Klausel in Vertr{\"a}gen auf. B{\"u}rokratie in Deutschland f{\"u}hrt zu hohen Kosten, besonders f{\"u}r kleine Unternehmen. Kosteneinsparungen sind der gr{\"o}ßte Treiber bei der Dekarbonisierung. Nachhaltigkeit wird immer wichtiger und kann {\"u}ber Zertifikate nachgewiesen werden. ▪ Im vierten Themenkomplex Software wurde die Anpassungsf{\"a}higkeit von ERP-Systemen bem{\"a}ngelt und automatische Bestellungen wurden kontrovers betrachtet. Die meisten Experten verzichten aus Sicherheitsgr{\"u}nden auf Cloud-basierte L{\"o}sungen aufgrund des hohen Risikos f{\"u}r Cyberangriffe und m{\"o}glicher Gefahren f{\"u}r die Supply Chain. ▪ In Themenkomplex f{\"u}nf wurden neue Technologien im SCM besprochen. AR wird f{\"u}r die Wartung von Maschinen eingesetzt und VR f{\"u}r Simulation und Planung. IoT wird f{\"u}r predictive Maintenance genutzt, Treiber der Automatisierung ist der Fachkr{\"a}ftemangel. Big Data \& AI sollen die Vorhersage der Nachfrage verbessern. Additive Fertigung hat Potenzial f{\"u}r Automatisierung und sinkende Kosten. Die Blockchain gilt als komplex und kann als geteilte Datenbank, Zahlungssystem und zur Rechnungsteilung dienen. ▪ Im sechsten Themenkomplex Sichtbarkeit halten Experten Transparenz f{\"u}r wichtig, sie ist noch zu gering aber bietet Potenzial zur Erkennung von Risiken. Tracking und Tracing ist intern verbreitet, international gibt es noch Probleme.

The analysis shows that the strengths of the area include its energy expertise, existing infrastructure with renewable energy potential, and availability of land for industrial development and settlement.
