DMBOK- Project Management Methodologies

What is “Agile” methodology?

Agile

• Simple meaning: Agile is like building something step by step while checking often if it works.

• Example: Imagine you’re building a Lego castle. Instead of waiting until the whole castle is done to show your friends, you show them after each wall or tower. If they don’t like something, you can fix it right away before finishing the whole thing.

• Why it matters: It lets people adjust quickly if needs change.

What is “Waterfall” methodology?

Waterfall

• Simple meaning: Do everything in a straight line, one step after the other.

• Example: Think of baking a cake. You mix the ingredients, bake it, then decorate it. You don’t taste-test until it’s finished, so if something goes wrong, you might have to start over.

• Why it matters: Works best when you know exactly what you want from the start.

What is Scrum Framework?

Scrum (a type of Agile methodology)

• Simple meaning: Work in small “sprints” with a team, then stop to see how it’s going before moving on.

• Example: Like running a relay race in short bursts instead of a long marathon. After each sprint, the team checks if they’re still going in the right direction.

• Why it matters: Encourages teamwork and quick adjustments.

What are “Lean Principles” or the “Lean Approach”?

Lean

• Simple meaning: Focus only on what’s needed and cut out waste.

• Example: If you’re making sandwiches for friends, you only use the ingredients they like and skip anything extra no one eats.

• Why it matters: Saves time, effort, and resources.

What is “Six Sigma” methodology?

Six Sigma

• Simple meaning: Do things in a very precise way so mistakes are super rare.

• Example: Imagine you’re filling jellybeans into jars. Six Sigma is about making sure every jar has the same number, almost perfectly every time.

• Why it matters: Helps create high-quality results with fewer errors.
