For a budget proposal that must beas accurate as possibleand supported by aWork Breakdown Structure (WBS)orProduct Breakdown Structure (PBS), thebottom-up estimate(A) is preferred. This method involves estimating costs for each task or deliverable in the WBS/PBS, then aggregating them to calculate the total budget. According toPMBOK, bottom-up estimation leverages detailed data, ensuring high accuracy, especially when a WBS is available.

Rough Order of Magnitude (ROM) (B):A high-level estimate with low accuracy (±50%), used early in projects, not suitable for detailed budgeting.

Analogous estimate (C):Relies on historical data from similar projects, less accurate than bottom-up when detailed WBS data exists.

Budget estimate (D):A general term, not a specific technique, and less precise than bottom-up.

The customer’s focus on incorporatingfuture functional requirementsindicates a need forperfective maintenance(B). Inapplication management, perfective maintenance involves enhancing software to add new features or improve functionality to meet evolving business needs, such as adding new modules or capabilities.

Preventive maintenance (A):Focuses on preventing issues by optimizing performance or addressing potential problems, not adding new features.

Corrective maintenance (C):Involves fixing bugs or errors, not incorporating new functionality.

Adaptive maintenance (D):Adapts software to environmental changes (e.g., new operating systems), not specifically for new functional requirements.

Perfective maintenance aligns with theSDLC’s maintenance phase, ensuring the software evolves to support future business requirements.

Outsourcing IT operations to an external vendor is a form ofrisk transfer(C), where the responsibility for managing certain risks (e.g., operational or technical risks) is shifted to the vendor. According toISO 31000, risk treatment strategies include transferring risk to a third party, often through contracts or outsourcing agreements, where the vendor assumes responsibility for mitigating specific risks.

Sharing (A):Involves distributing risk among multiple parties, not fully transferring it to one.

Retention (B):Means accepting the risk without mitigation, not applicable here.

Modification (D):Refers to changing processes or controls to reduce risk, not outsourcing.

To predict future customer purchases, the marketing department requiresadvanced analytics(B), which involves sophisticated data analysis techniques, such as predictive modeling, machine learning, and data mining. These technologies enable the department to analyze customer behavior, identify patterns, and forecast purchasing trends, supporting targeted advertising campaigns.

Records Management System (RMS) (A):Focuses on managing and storing records, not predictive analysis.

Ad hoc analysis (C):Allows for on-demand, one-off queries but lacks the predictive capabilities of advanced analytics.

Business Intelligence (BI) (D):Provides reporting and historical data analysis but is less focused on predictive modeling compared to advanced analytics.

Advanced analytics aligns withIT strategygoals of leveraging data for competitive advantage, as it supports predictive insights critical for marketing decisions.
