When presenting a project planning there are probably a lot of numbers and data that you need to present. Deadlines, people that need to do something a certain point in time, different phases, go/no-go decision points, milestones to be met, intermediate decisions to be taken, shifting responsibilities, regular meetings.
Presenting a project planning may be difficult to do and for your audience difficult to follow. Think about what can be visualized, for example by means of using a project planning diagram. Such a diagram can support the process as, if done correctly, can be easier to present by you and followed by your audience. Besides showing the project planning diagram on a screen you could also print it on a relatively large size of paper and give this to your audience as a hand-out. By means of this your audience can write thing on it to highlight wat is relevant and important for them as part of the project planning.
