A network diagram is a graphical tool to help you decide the sequence of tasks.
You can see which tasks go first, which come second, which can be done in parallel – and which tasks must be finished before another task can begin.

Explain the answer – you can’t install the latrine cap before you build it etc.
Ask participants where the list of tasks and activities comes from – – WBS – highlight the fact that the tools work together.
You can make the link to assumptions in the logframe becoming risks in the risk register and then the mitigation activities featuring in the WBS and now you are sequencing them.
Ask participants if they could organize the tasks in a different order. Ask them to give some examples – mic/text/screen. Explain that the next slide shows an example of this.
