Subtasking

Structuring of project in subtasks. These can be function-oriented, object-oriented, phase-oriented, or of mixed orientation.

Function-Oriented Structure

Tasks critical to project fulfillment are elaborated first.

Object-Oriented Structure

The project-as-object is subdivided into individual components, modules and parts.

Phase-Oriented Structure

Conception, definition, execution and application. A final report is prepared after each phase.

Mixed Orientation

Object-oriented or phase-oriented is preferred for upper levels; function-
oriented lower levels.

Work Packages

Job Scheduling

Routine tasks in large, risky projects are divided into small work packages.
