According to the CGEIT exam guide, the primary reason a CIO and IT senior management should stay aware of the business environment is to adjust IT strategy as needed. IT strategy is the plan that defines how IT will support and enable the business strategy and objectives of the enterprise. The business environment is the external and internal factors that affect theenterprise’s performance and success, such as market trends, customer demands, competitor actions, regulatory changes, technological innovations, etc. The CIO and IT senior management should stay aware of the business environment to identify and anticipate the opportunities and threats that may arise, and to align and adapt the IT strategy accordingly. This will help to ensure that IT delivers value, benefits and competitive advantage to the enterprise, and that IT risks are managed and mitigated effectively. References: CGEIT Exam Candidate Guide, page 13. CGEIT Certification, What is IT Strategy?, What is Business Environment?
