For handling up to 5,000 new cases per day with the capability for customers to attach files under 10 MB, Web-to-Case is the recommended feature. This allows customers to submit cases directly through a web form, including file attachments, efficiently scaling case creation capabilities while reducing the workload on support agents.

Given the requirements for quick iterations, speedy completion, and frequent updates, the Agile methodology is recommended. Agile allows for adaptive planning, evolutionary development, early delivery, and continuous improvement, facilitating rapid response to changes and ensuring close collaboration with the client for regular feedback and refinement.

To measure first-call resolution by channel, agent, and calendar month, a joined report is recommended. This type of report allows the combination of related reports into a single report with multiple blocks, enabling the analysis of data across different dimensions such as communication channels, individual agent performance, and timeframes, providing a comprehensive view of first-call resolution metrics.

Salesforce Data Cloud (Customer Data Platform) provides capabilities to unify structured and unstructured data sources such as chat and voice transcripts, loyalty programs, and service records. Through this unified data model, organizations can generate calculated insights, apply AI-driven sentiment analysis, and deliver personalized, predictive recommendations within Service Cloud and Agentforce experiences.
This use case aligns directly with Service Cloud + Data Cloud integration, as highlighted in the Spring '24 Release Notes, which introduced transcript unification and sentiment scoring for AI-powered service operations.
Option A focuses on static article recommendations, which do not analyze conversation data or sentiment.
Option C provides operational metrics via analytics dashboards but does not deliver AI-driven recommendations or sentiment analysis.

To meet the requirements of different access levels for account managers and support engineers, configuring Case Teams with appropriate roles and applying field-level security to the Personal Identifiable Information (PII) data field is advisable. This approach allows for granular control over access to case information and PII data, ensuring that each role has the necessary permissions while maintaining data privacy and security.
