4.3DX & digital transformation
Covers the three-stage distinction of digitization (localized IT-ization of existing operations), digitalization (digitizing whole business processes), and DX (transforming products, services, business models, and the organization with data and digital technology to establish competitive advantage); the use of stability-oriented SoR versus agility-oriented SoE; the DX promotion index; and legacy renewal and the "2025 cliff." The key is judging "mere IT-ization" from "true DX (business transformation)."

Localized IT-ization (digitization) such as turning paper into PDFs or replacing manual work with a tool; process digitalization (digitalization) that re-connects the whole business process from ordering to settlement digitally; and DX, which transforms products, services, and the business model itself with data and digital technology to build competitive advantage—these three differ in purpose and in management impact. The IT strategist's role is, in a scene where management is satisfied with "IT-ization," to discern whether it reaches true DX (transformation of the business model) and to judge what to propose next. This section covers the three-stage distinction, the use of SoR/SoE, and legacy renewal and the "2025 cliff," framed as the judgment of a strategist leading DX.
