1. Waterfall Methodology
Overview: The Waterfall methodology is a linear and sequential approach, often used in software development and manufacturing industries. Each phase must be completed before the next begins, ensuring a structured progression through project stages.
Key Phases:
Requirements
Design
Implementation
Verification
Maintenance
Advantages:
Clear structure and documentation.
Easy to manage and control due to its sequential nature.
Well-suited for projects with well-defined requirements.
Disadvantages:
Inflexibility in accommodating changes.
Potential for late discovery of issues.
Less effective for complex or iterative projects.
2. Agile Methodology
Overview: Agile is a flexible, iterative approach that emphasizes collaboration, customer feedback, and small, rapid releases. It is particularly popular in software development.
Key Principles:
Individuals and interactions over processes and tools.
Working software over comprehensive documentation.
Customer collaboration over contract negotiation.
Responding to change over following a plan.
Advantages:
High adaptability to changes.
Continuous delivery of valuable products.
Enhanced customer satisfaction through regular feedback.
Disadvantages:
Requires high customer involvement.
Can be less predictable due to its flexibility.
May lack formal documentation.
3. Scrum
Overview: Scrum, a subset of Agile, focuses on small, cross-functional teams working in sprints (typically 2-4 weeks) to deliver increments of the product. Each sprint ends with a review and retrospective.
Key Roles:
Product Owner: Defines the product backlog and prioritizes work.
Scrum Master: Facilitates the process and removes impediments.
Development Team: Delivers the product increment.
Advantages:
Promotes teamwork and accountability.
Regular feedback and adjustment improve quality.
Flexibility to adapt to changing requirements.
Disadvantages:
Can be challenging to scale for larger teams.
Requires disciplined adherence to Scrum practices.
Potential for scope creep without strong backlog management.
4. Kanban
Overview: Kanban focuses on visualizing work, limiting work-in-progress, and optimizing flow. It uses a Kanban board to represent the workflow and prioritize tasks.
Key Elements:
Visual Board: Columns representing different stages of the workflow.
Work-in-Progress Limits: Restrict the number of tasks in progress.
Continuous Delivery: Work items are delivered as soon as they are ready.
Advantages:
Visual management improves transparency.
Flexibility to handle changes smoothly.
Continuous delivery enhances productivity.
Disadvantages:
Less structured than other methodologies.
Requires disciplined work-in-progress limits.
May lead to issues if not properly managed.
5. Lean
Overview: Lean methodology aims to maximize value by minimizing waste. It focuses on delivering more value to customers with fewer resources.
Key Principles:
Identify Value: Define what is valuable to the customer.
Map Value Stream: Analyze the flow of materials and information.
Create Flow: Ensure smooth and continuous workflow.
Establish Pull: Produce only what is needed, when it is needed.
Seek Perfection: Continuously improve processes.
Advantages:
Reduces waste and enhances efficiency.
Focuses on customer value.
Encourages continuous improvement.
Disadvantages:
Requires a cultural shift towards continuous improvement.
Can be challenging to implement in traditional environments.
May need significant changes to existing processes.
6. Six Sigma
Overview: Six Sigma is a data-driven methodology aimed at reducing defects and improving quality. It uses statistical tools and techniques to identify and eliminate causes of variation.
Key Phases (DMAIC):
Define: Define the problem and project goals.
Measure: Collect data and measure current performance.
Analyze: Identify root causes of defects.
Improve: Implement solutions to improve performance.
Control: Sustain improvements over time.
Advantages:
Strong focus on quality and data-driven decision-making.
Reduces defects and improves customer satisfaction.
Provides a structured approach to problem-solving.
Disadvantages:
Can be resource-intensive and time-consuming.
Requires specialized training (e.g., Six Sigma belts).
May be too rigid for dynamic environments.
7. PRINCE2 (Projects IN Controlled Environments)
Overview: PRINCE2 is a process-based methodology widely used in the UK and internationally. It focuses on business justification, defined organization structure, product-based planning, and a stage-gate approach.
Key Features:
Business Justification: Ensures projects align with business goals.
Defined Roles and Responsibilities: Clarifies team roles.
Product-Based Planning: Focuses on deliverables rather than activities.
Stage-Gate Process: Divides the project into manageable stages.
Advantages:
Comprehensive framework with clear guidelines.
Strong focus on business justification and control.
Scalable for projects of all sizes.
Disadvantages:
Can be bureaucratic and documentation-heavy.
Requires extensive training and certification.
May be less flexible for dynamic projects.
Conclusion - Project Management Methodologies Compared
Project Management Methodologies Compare. Choosing the Best One depends on the nature of your project, team structure, and organizational culture. Waterfall offers a structured approach, while Agile and its subsets like Scrum and Kanban provide flexibility. Lean and Six Sigma focus on efficiency and quality, and PRINCE2 offers a comprehensive, scalable framework. Understanding the strengths and weaknesses of each methodology will help you navigate your projects to success.

In the mentioned list, only PRINCE2 is a project management methodology (PMM). There are very sensible differences between the terms: framework, methodology, method, approach, mindset etc., especially when they are used for project management, usually in the wrong way.
