You can use roadmap templates to display parallel project tracks or multiple phases effectively. Roadmap PowerPoint templates are versatile and can show overlapping timelines, dependencies, and simultaneous activities. The following points will help you achieve it:
1. Use multiple tracks or swimlanes for parallel workflows.
2. Use color coding and icons to classify different phases.
3. Show overlapping timelines and dependencies with arrows or connectors.
4. Design stacked timelines or use SmartArt for custom parallel roadmaps.
5. Use pre-designed roadmap templates that allow for simultaneous project or phase tracking.
