Whilst you’re currently using Microsoft Word for this, it would actually be much easier to do this using Excel (and create a Gantt Chart) OR you could use something like Asta Power Project[1] which is used in the Construction Industry as well as with Technology Organisations, Engineering, Manufacturing, Oil & Gas and Financial Services etc which rely on projects running in parallel.
The reason I recommended the Asta Power Project tool is because you can:
- Create accurate schedules easily using a drag/drop feature
- Have complete visibility over multiple projects in real-time
- Optimise your project resources
- Access powerful reporting tools
- ETC
I've actually used the Asta Power Project Software myself; it's pretty powerful and feature rich.
