How can I change default view?
This is one of the frequently asked question from professionals learning MS Project in their initial stages learning.
Usually you get Timeline and Gantt Chart when you open MS Project tool.
If you want to see only gantt chart view, then you can visit View tab => uncheck Timeline checkbox.
But, you may want to see only Gantt chart view every time you open MS project tool. Setting it up is very easy.
Open Backstage (File) => Options => General Section.
Look for Default View filed under project view subsection.
Click the dropdown box and select Gantt Chart.
Close the file and open again. Now you can see Gantt Chart as default view when you open tool.
