Domain or Industry: This relates to the domain or industry of the organization(s) they have worked in. For instance a project manager with Banking industry experience would have different domain knowledge as compared to a project manager from Construction industry, who would have different domain knowledge as compared to a project manager from Pharma.
Function: This represents the specific function or department in which the project manager has worked in. For instance, one project manager may have IT Infrastructure experience (within a Bank), while another may have worked with projects only within the Marketing group (of the same Bank).
Objective of the Project: Two Web projects may have completely different objectives - one may be to create a new website, while the other may be to redesign a website, while a third one may be to migrate the website to a different infrastructure. A project manager may specialize in managing projects related to achieving on type of project objective. For instance, over time I have started to specialize in managing website and mobile app redesign projects.
Project Management Methodology: There are many methodologies to manage projects - Waterfall, Iterative, Spiral, Agile, Lean etc. Depending upon the project methodologies used by a Project Manager as well as his or her understanding of these methodologies, his or her capacity may be limited to managing projects within certain methodologies.
Size of the Project Budget: Project Budgets vary from anywhere in the range of $5,000.00 to upwards of $100M. And based on size of the project budget a project manager manages, their capacity to manage budget could vary widely.
Size of the Project Team(s): While one project manager may be working with only 3 team-members, another project manager may be working on a massive multi-year project with 3000 people working in multiple teams, even representing multiple organizations.
