A tool by definition is used for a specific purpose or purposes. There are things it can and cannot do. Similarly, PowerPoint is a tool which has a certain usage.
PowerPoint is meant to be used as a ‘visual tool’ to help you deliver a talk. It is a support tool. It is not a word document where you type in a report. Hence, when you need to make a report or an analysis, you need MS Word. When you present the analysis and want to enhance the speech with visuals, use PowerPoint.
Do not use PowerPoint as a sticky note by putting all the content on the slides so that it will help you remember all your points. Write in brief and back yourself.
