According to the CTSC exam content manual 1 , transform and return costs are two of the five cost categories in the SCOR model. Transform costs are the costs associated with converting raw materials into finished products, such as labor, materials, energy, depreciation, etc. Return costs are the costs associated with handling and disposing of defective or excess products, such as transportation, inspection, rework, recycling, etc. Transform costs are often captured in the cost of goods sold (COGS), which is the direct cost of producing the goods sold by a company. Return costs are often captured in claims, which are the expenses incurred by a company when customers return defective or unsatisfactory products.

According to the CTSC exam content manual 1 , implementing electronic data interchange (EDI) can provide benefit in establishing business relationships with suppliers by building trust, which is one of the key elements of supplier relationship management. EDI can help to build trust by enabling faster, more accurate, and more secure data exchange, reducing errors and disputes, improving communication and collaboration, and enhancing customer satisfaction.

According to the ASCM CTSC Exam Content Manual, a digital supply chain integrator is a role that involves connecting the digital and physical supply chain elements, and enabling the flow of data and information across the end-to-end supply chain1. This requires reaching across functional and technological boundaries to seek information and understand-ing, and to collaborate with internal and external partners to optimize the supply chain performance2. The other options are not specific to the digital supply chain in-tegrator role, as they are common behaviors for any supply chain professional. 1 : ASCM CTSC Exam Content Manual, page 9. 2 : 3

According to the CTSC Enterprise and Supply Chain Management (ESCM) manual, human capital and talent is one of the most critical non-technological factors to execute a digital supply chain transformation 1 . Human capital and talent refers to the skills, knowledge, abilities, and attitudes of the people who work in the supply chain, as well as the processes and practices to attract, develop, and retain them 1 . A successful digital supply chain transformation requires a workforce that is capable of using and adapting to digital technologies, such as cloud computing, artificial intelligence, big data, and robotics 1 . It also requires a culture that fosters innovation, collaboration, and continuous learning 1 . Therefore, human capital and talent is essential for enabling and sustaining a digital supply chain transformation 1 .

Ac-cording to the CTSC Exam Content Manual1, one of the required key management capabilities for implementing new supply chain capabilities is inspiring and influential leadership. This means having the ability to communicate the vision and goals of the transformation, motivate and empower the team, and foster a culture of innovation and collaboration.

According to the ASCM CTSC Exam Content Manual, when designing a new demand-driven supply chain, technologies should be evaluated after the supply chain is designed. This is because the supply chain design should be based on the customer needs, the business strategy, and the supply chain capabilities, not on the available technologies 1 . The technologies should be selected to support and enable the supply chain processes, not to dictate or constrain them 1 . Evaluating technologies after the supply chain is designed can help to avoid unnecessary costs, complexity, and risks, and to ensure alignment and integration across the supply chain network 1 .

According to the ASCM, one of the key steps in supply chain transformation is to define the organizational roles and responsibilities for each supply chain activity, and to ensure that they are aligned with the business strategy and customer expectations 1 . The ASCM also suggests that the supply chain activities can be grouped into three main categories: sales, operations, and logistics 2 . These categories reflect the core functions of the supply chain, from planning and executing the demand and supply, to delivering the products and services to the customers 2 . Therefore, organizational roles and responsibilities should focus on these three areas to clarify who is responsible and accountable for each supply chain activity after the transformation initiative is complete. Some examples of the roles and responsibilities in each area are:

Sales: Responsible for generating and managing the customer demand, forecasting the sales volume, and ensuring customer satisfaction and loyalty. Examples of roles are sales manager, account manager, customer service representative, and demand planner 2 .

Operations: Responsible for producing and sourcing the products and services, managing the inventory and quality, and optimizing the cost and efficiency. Examples of roles are operations manager, production manager, procurement manager, and quality manager 2 .

Logistics: Responsible for transporting and distributing the products and services, coordinating with the suppliers and carriers, and ensuring the delivery speed and reliability. Examples of roles are logistics manager, warehouse manager, transportation manager, and distribution manager 2 .

According to the CTSC Exam Content Manual, one of the areas that leadership should focus on while developing a roadmap for supply chain transformation is customers, talent, and risks 1 . Customers are the ultimate source of value and demand for the supply chain, and understanding their needs and expectations is essential for designing a customer-centric supply chain strategy 1 . Talent is the human capital that drives the supply chain performance and innovation, and developing the skills and capabilities of the workforce is critical for enabling a successful supply chain transformation 1 . Risks are the potential threats and uncertainties that can disrupt or damage the supply chain, and identifying, assessing, and mitigating them is vital for ensuring the resilience and sustainability of the supply chain 1 . The other options are not the most pertinent areas for leadership to focus on while developing a roadmap for supply chain transformation, as they are more operational or tactical aspects of the supply chain, not strategic or transformational. Suppliers, inventory, and payment terms are examples of the sourcing process elements that affect the cost, quality, and availability of the supply chain inputs 2 . Warehouses, carrier relationships, and technology are examples of the delivery process elements that affect the efficiency, responsiveness, and reliability of the supply chain outputs 2 . Data centers and web portal are examples of the information technology infrastructure that supports the supply chain integration and visibility 3 .
