According to the CTSC Exam Content Manual 1 , one of the key capabilities for supply chain resilience is agility, which is the ability to respond quickly and effectively to unanticipated disruptions. Agility enables supply chain professionals to adapt to changing customer needs, market conditions, and operational challenges. Another key capability for supply chain resilience is velocity, which is the speed at which products and information flow through the supply chain. Velocity enables supply chain professionals to reduce lead times, improve service levels, and increase customer satisfaction. Therefore, increasing levels of agility and velocity is a measure that should be adopted for supply chains to become more resilient to unanticipated disruptions. Option A, implementing internal standards of risk awareness and response, is a measure that can help mitigate the impact of disruptions, but it does not necessarily increase the resilience of the supply chain. Option B, ensuring that there is clear responsibility for identifying risk, is a measure that can help prevent or reduce the likelihood of disruptions, but it does not necessarily increase the resilience of the supply chain. Option C, decreasing inventory levels to the minimum level possible, is a measure that can reduce costs and waste, but it can also increase the vulnerability of the supply chain to disruptions.

Porter’s Five Forces is a model that identifies and analyzes five competitive forces that shape every industry and helps determine an industry’s weaknesses and strengths 1 . The five forces are: competition in the industry, potential of new entrants, power of suppliers, power of customers, and threat of substitute products 1 . The company has used this tool to assess the attractiveness and profitability of the airline industry by evaluating the intensity of each force.

According to the ASCM CTSC Exam Content Manual, ecological, ethical, and economic are the three major categories of practices that an organization should evaluate as it transforms its processes to be more sustainable. These categories are also known as the triple bottom line of sustainability, which measures the social, environmental, and financial impacts of an organization’s activities 1 . Ecological practices refer to the environmental aspects of sustainability, such as reducing greenhouse gas emissions, waste, and resource consumption, and enhancing biodiversity and ecosystem services 1 2 . Ethical practices refer to the social aspects of sustainability, such as respecting human rights, labor standards, and diversity, and promoting health, safety, and well-being of employees and communities 1 3 . Economic practices refer to the financial aspects of sustainability, such as creating value for stakeholders, ensuring fair and transparent transactions, and investing in innovation and development 1 4 .

According to the CTSC Enterprise and Supply Chain Management (ESCM) manual, the next step after setting improvement priorities on the basis of strategic objectives is to design the transformation road map 1 . The transformation road map is a document that outlines the vision, goals, scope, timeline, milestones, deliverables, resources, risks, and dependencies of the supply chain transformation project 1 . It also defines the roles and responsibilities of the project team and the stakeholders, and the communication and governance mechanisms 1 . The transformation road map helps to guide the execution of the project, monitor the progress and performance, and ensure alignment and collaboration among the project participants 1 .

According to the CTSC Exam Content Manual, process harmonization is the degree to which an organization’s processes are standardized and aligned across its business units 1 . Documenting supply chain processes and maintaining updated documentation are used to achieve process harmonization, as they help to ensure consistency, transparency, and compliance of the processes across the organization 2 . Documenting supply chain processes also facilitates the identification of best practices, gaps, and improvement opportunities for the processes 2 .

one of the most prominent characteristics of a digital supply chain is the access to latest point-of-sale (POS) data across the network. POS data refers to the information collected by retailers at the point of purchase, such as the product, quantity, price, date, time, and location of the transaction 3 . Access to this data enables digital supply chains to have real-time visibility of customer demand, inventory levels, and market trends, and to use advanced analytics and artificial intelligence to optimize planning, forecasting, replenishment, and delivery 1 2 . Access to POS data also helps digital supply chains to improve customer satisfaction, reduce costs, increase sales, and enhance collaboration among supply chain partners 1 2 .

According to the ASCM CTSC Exam Content Manual, one of the first steps in developing a transformational supply chain strategy is to “determine the current and future needs and expectations of the customers, and align the supply chain strategy with the business strategy and customer value proposition” (p. 16). This helps to ensure that the supply chain transformation is customer-centric and focused on delivering value to the end users. The other options are also important, but they should be done after the initial determination of the customers’ needs.
