Using a House of Project Management (HoPM) approach can help establish formal communication channels in the following ways:

1. **Defined Structure and Roles:** HoPM provides a clear organizational structure for project management, specifying roles and responsibilities. This clarity helps ensure that everyone knows who to communicate with regarding project updates, issues, and changes.
2. **Standardized Processes:** HoPM encourages the implementation of standardized communication processes and templates, making it easier for team members to share information consistently. This can include project briefs, status reports, and decision logs.
3. **Integrated Communication Tools:** HoPM often advocates for the use of integrated project management tools that facilitate communication among team members. These tools can centralize project information, making it accessible and ensuring that everyone is on the same page.
