The best strategic approach is to invest in targeted training programmes for existing staff in relevant emerging technologies (B). The ITIL 4 Specialist: Create, Deliver and Support documentation (Section 3.3.2) states:
"Investing in training leverages existing staff knowledge, aligns competencies with new market needs, and ensures cultural continuity, which is critical during expansion." This is cost-effective and builds internal capability, unlike option A (expensive hiring), option C (relinquishes control), or option D (disruptive restructuring). The guide notes: "Skill development supports the service value system's adaptability." Reference: ITIL 4 Specialist: Create, Deliver and Support, Section 3.3.2 - Competency Development.
