research paper: Build a Network Diagram for developing a clincial trial management software

The first step in building the network diagram is sequencing all of the activities.

A completed network diagram enables you to able to determine: $(1)$ a project's scheduled completion time, $(2)$ the slack or float of project activities, and $(3)$ the critical path of your project.

Build a Project Network $($or a Partial Network$)$

Brainstorm the activities required to complete the work packages. Record on note cards or Post$-$it notes. Don$$t worry about the order or sequence.

Sequence the note cards or Post$-$it notes with the activities. Determine:

The order of activities

Which activities can occur in parallel

Which activities require dependencies

Mandatory: before the activity can begin or end the completion of another task is required.

Discretionary: a best practice or convenience. However, the subsequent task can begin if the discretionary dependency is not completed.

External: requires additional project or process, such as permits.

Internal: dependencies within the control of the project team.

Place the notes on a wall based steps $1$ and $2.$
