Elaborate Requirements, Confirm Scope, Plan Project / Sprints, and Infrastructure Sizing are all part of...

Comprehensive and Detailed Explanation:

According to the Guidewire SurePath methodology, these specific activities are the core objectives of the Inception Phase (Option D).

Confirm Scope:The primary goal of Inception is to move from the high-level scope defined in Pre-Inception to a detailed, agreed-upon scope (Minimum Viable Product).

Elaborate Requirements:The team conducts workshops (often called "Elaboration" sessions) to break down high-level requirements into detailed User Stories.

Infrastructure Sizing:While initial estimates may happen earlier, the definitive infrastructure sizing (hardware, cloud resources) is finalized during Inception once the scope and architecture are understood.

Plan Project / Sprints:Inception concludes with a "Conceptual Sprint Plan" or release schedule, mapping out which stories will be delivered in which sprint.

Why other options are incorrect:

A. Development:This phase is forexecutingthe plan (building and testing), not defining the scope or sizing the infrastructure.

C. Pre-Inception:This phase is forpreparationand mobilization (staffing the team, setting up logistics), but the detailed "Elaboration" and "Sizing" happen once the full team starts in Inception.
