The Relationally Intelligent Project Manager: Project Management Systems to Turn Down the Emotional Temperature on Your Project

Effective project management systems will help settle the emotions of people involved with your project.

This is because well-run systems will help manage people's expectations and give them ways to trust what is happening on the project. So then there's less of people going at each other.

Here's six systems that will help you:

Project requirements list with change log - Everyone can be clear about what is part of the project and what is not.
Timeline - Everyone can know what is happening when.
Master task list - Everyone can see what is being worked on and trust that what they're concerned about on the project is being addressed.
Communication schedule - Everyone can know when to expect the next set of information.
Master document repository - Everyone can trust that all of the information about the project is secure in one place.
Development roadmap - Everyone can see what your future plans are and trust that there's a long-term plan beyond what's happening now.
