Alternative Hierarchy type Registers

An Alternative Hierarchy is a type of Register that enables a client to create alternative project hierarchies which when linked to schedule tasks enable the pivoting of task data from the original project schedule structure into the AH Register defined multi-level structures.

Example: MIL-STD-881F Appendix A

The military standard 881F is the US Department of Defense’s (DOD) direction on how to breakdown the work necessary to build defense material items such as aircraft, sea, and space systems. Note that not all government contracts awarded will include all sections of the MIL-STD-881F hierarchy.

Level 1: Entire system and/or program
Level 2: Major Elements
Level 3: Subsystems
Level 4: Sub-elements of the Subsystems
Level 5: Lower-level elements

The management and reporting on the Aircraft System Alternative Hierarchy would leverage the relationship of Level 5 (lower-level elements) to Schedule Tasks to map and roll-up data into the customer’s work breakdown structure (WBS) as shown in the illustration below.
