Valuable investments is the HVIT objective most closely connected to benefits realized from effective use of products and services. The question points to competences such as improved decision-making, which are not just technical outputs but business-enabling outcomes. In HVIT, investments are considered valuable when they contribute to meaningful outcomes, capabilities, and performance improvements.

Fast development is about speed and flow of creation and delivery. Resilient operations is about stability and recovery. Assured conformance is about governance, control, and compliance. Only valuable investments directly matches the idea that effective use of digital services leads to better organizational capability and decision-making.

Therefore A is correct.

=========

Large and complex environments often fail in unexpected ways. Chaos engineering is a technique used to improve resilience by deliberately testing how systems behave under failure conditions. This helps organizations expose weaknesses, improve recovery mechanisms, and reduce user-impacting incidents over time.

A is not the best fit for reducing operational fragility. C improves quality in delivery pipelines, but it does not directly test operational resilience in complex live-like environments. D is a useful team agreement on completion criteria, but it is too limited for this scenario.

B is best because chaos engineering directly targets the uncertainty and fragility that often come with complex infrastructures, which is very consistent with HVIT’s resilience focus.
