There are two models for implementing a Project Portfolio Management (PPM) system:
- The budget alignment model
- The engagement profitability model
The budget alignment model corresponds with an operational environment where the value of projects varies, and project costs are expense overhead. Decisions and behavior are driven by the need to squeeze value out of the available budget. Examples of the budget alignment business model include enterprise IT and product development organizations.

Examples of the engagement profitability model include IT services firms and professional services departments within product companies.
