Issue/Introduction

How is Remaining Availability on the Project Staff Member page calculated in Classic UI?

Resolution

Values are determined based on the Resource's availability from their calendar, Date of Hire, Date of Termination and the amount of hours already allocated on existing investments based on investment dates.

The overall Remaining Availability calculation for a resource on a project:

remaining availability = (availValue - allocValue)

availValue = sum(resource's availability curve clipped to max(project start, resources team start on this project, actThru, resource dot)
allocValue = allocation of the resource on all open projects during the projects time periods

 

The Remaining Availability calculation for an allocation segment is:

Allocation segments are shown on the Team Staff Member Properties page.

remaining availability = (availValue - allocValue) 

availValue = sum(resource's availability curve from segment start date to segment finish date)
allocValue = sum(resource's allocation curve from segment start date to segment finish date)

 

Time periods calculations:

The date is used as a factor in determining remaining availability and is determined by the latest date for the identified attributes.

start of time period = max(project start, team start, resource doh, max assignment actthru for that resource on that project)
finish of time period = min(project finish, team finish, resource dot)

doh = Date of Hire

dot = Date of Termination
