How to compete for resources with other project leaders
I handed over one of my projects to another project lead. Before that, I shared my resources more freely between my four projects, to ensure stress was bearable for all and milestones were met.
I defined a fixed resource group and handed it over to the new lead but I see him always taking/wanting everything when I'm giving him something.
Are there literature recommendations or tips on how to successfully compete with other project leads for valuable resources?
There should be a decision authority, like a steering committee, who allocates resources to programs and projects within its scope. If you're a project leader of a few of them, your task is to build a case for what you need. That same authority would also handle and provide solutions for those who are trying to consume more than what was allowed.
You need to escalate this issue you're experiencing to this decision authority to get a resolution.
