Project Management Methodology FAQ

1. What is the difference between Agile and Waterfall methodologies?

Agile and Waterfall represent fundamentally different approaches to project management. Agile is flexible and iterative, allowing for changes and adaptations throughout the project lifecycle. It encourages frequent reassessment of project directions and close collaboration among cross-functional teams.

In contrast, Waterfall is a linear and sequential approach where each phase of the project must be completed before the next begins, making it suitable for projects with well-defined requirements that are unlikely to change.

 

2. How do Scrum and Kanban differ in managing projects?

Both Scrum and Kanban are Agile methodologies, but they differ in structure and focus. Scrum is organized around fixed-length sprints and requires regular meetings, such as daily stand-ups and sprint reviews, making it highly structured.

Kanban focuses on visualizing work, limiting work in progress, and achieving flow. It does not prescribe sprints or frequent meetings, making it more flexible and continuous compared to Scrum.

 

3. What are the main differences between Lean and Six Sigma methodologies?

Lean and Six Sigma both aim to improve processes, but their approaches and focuses differ significantly. Lean emphasizes eliminating waste and optimizing process efficiency to enhance flow and deliver value faster.

Six Sigma focuses on reducing defects and variability through data-driven techniques and rigorous process control. Lean is more about speed and efficiency, while Six Sigma prioritizes precision and quality control.

 

4. In what ways do PRINCE2 and PMI/PMBOK differ in their approach to project management?

PRINCE2 and PMI/PMBOK offer structured approaches to project management but differ in flexibility and application. PRINCE2 provides a highly structured method with a clear framework of stages, roles, and processes, and is often considered more prescriptive.

PMI/PMBOK is a guide that outlines best practices and processes across different knowledge areas and is more of a descriptive framework, allowing for greater flexibility in application across various industries.

 

5. When would one choose the Critical Path Method (CPM) over the Program Evaluation and Review Technique (PERT)?

The choice between CPM and PERT typically depends on the need for accuracy in schedule planning. CPM is used when the durations of project activities are known and fixed, making it suitable for projects where time estimates can be reliably predicted.

PERT, on the other hand, is used when activity durations are uncertain and variable, making it ideal for projects that require flexibility in handling unknowns and where estimates are based on probabilities.

 

6. What are the advantages of using PRINCE2 over Agile methodologies?

PRINCE2 offers a highly structured approach with defined roles, responsibilities, and processes, which can provide better control and clarity for projects that need rigorous management.

It is particularly advantageous for large, complex projects where scope, time, and cost must be closely monitored. Agile methodologies, while flexible and adaptive, might not provide the same level of control and predictability as PRINCE2, making PRINCE2 more suitable for projects in highly regulated industries.

 

7. How do the goals of Lean differ from those of the Critical Path Method (CPM)?

Lean focuses primarily on eliminating waste and improving process efficiencies to deliver value more quickly and efficiently. It is generally applied in continuous production and ongoing operations.

In contrast, CPM is designed to plan and control projects by determining the longest sequence of dependent tasks, focusing on minimizing project duration and optimizing resource allocation. While Lean aims for overall efficiency and flow, CPM targets effective project scheduling and delivery.

 

8. When to use Six Sigma instead of Kanban in project management?

Six Sigma should be used when the project goal is to significantly improve the quality of outputs by identifying and removing causes of defects and minimizing variability in manufacturing and business processes.

It is best for projects where precision and defect reduction are critical. Kanban, on the other hand, is more suitable for projects that benefit from continuous workflow improvements, focusing on reducing time to deliver and enhancing flexibility in production or project tasks.

 

9. What distinguishes the PMI/PMBOK guidelines from the PERT methodology?

PMI/PMBOK offers a broad framework that covers various project management aspects, providing guidelines across multiple knowledge areas like scope, schedule, cost, quality, and risk management.

It’s a comprehensive guide for best practices rather than a specific methodology. PERT, however, is specifically a scheduling technique that helps plan and coordinate tasks in a project, particularly useful in estimating time and managing dependencies in projects with uncertain timelines.

 

10. Which project management methodology is better suited for IT development projects: Scrum or Waterfall?

Scrum is generally better suited for IT development projects, especially in environments where requirements can change frequently, and innovation and speed are prioritized. Its iterative approach and flexibility allow teams to adapt to changes quickly and deliver parts of the project in stages.

Waterfall, with its sequential phase completion requirement, is less adaptable to change and therefore better suited for projects with well-defined and unchanging requirements, such as construction or hardware manufacturing.
