A strategy that has worked well for our team has been to keep a consistent project hierarchy and standardize workflows across projects. It makes portfolio reporting and cross-project visibility a lot easier.
We use Celoxis alongside our project management processes, as it gives a good view of resource planning, portfolio health, and executive reporting all in one place. But each team is different, so I think the right configuration depends on your organization and how complicated your portfolio is.
Reporting has also become much more useful for stakeholders by focusing dashboards on key KPIs, rather than trying to track everything.
I would like to hear what has worked best for your team in terms of best practices or experience. Any thoughts?
