• 📦 project — a single effort to create a specific product, service, or result
• 🔗 program — a group of related projects managed together to achieve a bigger goal and gain extra benefits
• 🗂️ portfolio — a collection of projects and programs (not necessarily related) aligned with the organization’s overall business goals

👉 simple way to remember:

• project = one effort
• program = related projects
• portfolio = everything combined

👉 hierarchy:
project → program → portfolio
