Chart the sequence of stages and steps to reflect the intrinsic and architectural dependencies inherent in the project. An output or product of one task will usually be the input to another, and this will be the primary driver in determining the task dependencies and workflow. Determine whether the successor task references (throughput) or updates (entry requirement) the input product. Some inputs may be sourced from outside the project. Identify these External Inputs (., Long Range System Plan, Standards, Project Initiation report of another project, etc.). Review the dependencies determined by the task inputs and outputs. Review the dependency types between the tasks. Tasks are not necessarily.
