Organizations increasingly rely on BYOD and remote work to attract talent, boost productivity, and stay resilient - yet many still struggle to prove what IT contributes beyond "it works" and "it costs." When performance is reduced to availability and budgets, strategic decisions become guesswork: security investments are hard to justify, governance turns into paperwork, and modern workplace programs drift between convenience and compliance. This book introduces an information model that makes IT performance measurable and manageable by connecting strategy, governance, and day-to-day operations in one coherent logic. Building on the IT Balanced Scorecard and aligned with COBIT 2019, the model is grounded in a structured research foundation and validated through an empirical study. It offers a practical pathway to translate business goals into performance targets, select truly decision-relevant KPIs, and design governance-compatible controls-so that BYOD and remote work remain not only efficient, but also secure, auditable, and clearly tied to business value. Rather than adding another framework, the approach helps organizations orchestrate what they already use: objectives, metrics, controls, and responsibilities. The result is a transparent performance narrative that supports management decisions, strengthens accountability, and turns the modern workplace from a "necessary risk" into a measurable strategic capability.
