Explanation
According to the ASCM CTSC Exam Content Manual, one of the first steps in initiating a digital supply chain transformation is to "identify the business drivers and opportunities for transformation, and prioritize them based on their potential impact and feasibility" (p. 15). This helps the company's leadership to align the transformation objectives with the strategic goals of the organization, and to allocate resources accordingly.
The other activities mentioned in the options are also important, but they should be done after the initial identification and prioritization of the areas of the business that can benefit the most from the transformation.
