Step-by-Step Comprehensive Detailed Explanation

Understanding Work Calendars in Certinia PSA

Work calendars define the default number of hours per day and week that a resource is expected to work.

They are crucial forresource scheduling, utilization calculations, and capacity planning​.

Every activePSA Resource must have an associated work calendarto allow project assignments.

Scenario Analysis

Your company hasboth full-time and part-time resources.

Full-time resources have astandard workweek(e.g., 40 hours per week).

Part-time resources havevariable work hoursbut are estimated at20 hours per week for planning purposes.

This means you needat least one calendar for full-time and one for part-time workers.

Why Option B is Correct

Creating asingle full-time work calendar(e.g., 40 hours per week) covers all full-time employees.

Creatingone part-time work calendar(e.g., 20 hours per week) provides a consistent framework for part-time resource planning​.

This approach ensuresstandardized reporting, scheduling, and forecastingwithout unnecessary complexity.

Why the Other Options Are Incorrect

A. One full-time work calendar, and one work calendar for each unique part-time contract

This would requiremultiple work calendars for different part-time contracts, making resource scheduling overly complex.

Since management has agreed on an estimated20 hours per weekfor all part-time workers, a single part-time work calendar suffices.

C. One full-time work calendar, one part-time work calendar, and one generic flexible work calendar

Aflexible work calendaris not necessary if all part-time workers are estimated at 20 hours per week.

Work calendars should align withclear scheduling rules, not individual flexibility.

Implementation in PSA
