A gap analysis is performed during the implementation planning phase to identify the differences between the current payroll processes and the capabilities of the new system. During this process, project teams must prioritize how " gaps " will be addressed. This includes evaluating " delivered functionality " (Option D) to see if it meets existing needs, considering " future planned vendor enhancements " (Option A) that might resolve a current gap later, and identifying " items handled by an outside interface " (Option B), such as benefit providers or GL systems. Prioritizing these areas helps determine whether a process must be changed, or if a system customization is required. However, " file security permissions " (Option C) are a standard system configuration task rather than a component of the gap analysis. While security is vital, it does not represent a " gap " in process vs. functionality that requires strategic prioritization during the analysis phase.
