What types of professionals do you reach out to when you encounter a problem on a project that you can’t solve yourself?

" Even though I am well qualified to work on the projects I am assigned, I recognize my limitations. I am more than willing to reach out to other professionals when I need assistance. Individuals I usually contact include the other members of my team, my management, professionals from other organizations within the company such as software and electrical engineers, the vendor teams I work with, my pool of consultants, and subject matter experts from around the globe. I have developed a very reliable portfolio of resources I can use whenever I encounter a problem I can't solve myself."
