Agile is not a single method, but a family of approaches built around shared values such as delivering value early, collaborating closely with customers, responding to change, and continuously improving. When organizations say, “We are doing Agile,” they may be referring to Scrum, Kanban, Lean, Extreme Programming (XP), Disciplined Agile, SAFe, or a hybrid approach that combines practices from several methods. This chapter provides a practical guide to the major Agile methodologies, focusing not on memorizing every detail of every framework, but on understanding why different approaches exist, when each is most useful, and how to select a method that fits the nature of the work rather than forcing the work to fit a particular framework. This broader understanding is especially important for the PMI-ACP exam, which extends beyond Scrum and expects familiarity with iteration-based and flow-based methods, Lean thinking, technical practices, governance-oriented approaches, and Agile methods for scaling across larger organizations.
By the end of this chapter, you should be able to:
- Explain why Agile has many methodologies instead of one universal method.
- Distinguish between iteration-based, flow-based, Lean, governance-oriented, hybrid, and scaling approaches.
- Describe Scrum, XP, Crystal, FDD, Lean, Kanban, Scrumban, DSDM, Disciplined Agile, SAFe, LeSS, Nexus, and Scrum of Scrums at a high level.
- Choose an Agile approach based on context, team size, uncertainty, governance needs, delivery rhythm, and organizational constraints.
- Recognize common methodology selection mistakes in PMI-ACP-style questions
- 3.1: Mapping to Exam Content Outline
- This page connects Agile methodologies with PMI-ACP exam themes, stressing value delivery, collaboration, and adaptability. It discusses methodologies like Scrum, Kanban, and Lean, encouraging the choice of approaches based on context rather than rote memorization. The emphasis is on Agile values such as transparency and frequent delivery.
- 3.2: Guide to Various Methodologies
- This page discusses the variety of Agile methodologies, emphasizing that Agile encompasses multiple approaches tailored to different contexts. The selection of a suitable method should be based on specific team challenges rather than popularity. Frameworks like Scrum, Kanban, and Lean cater to diverse needs, addressing factors such as complexity, delivery rhythm, and technical risk.
- 3.3: Chapter Summary
- This page outlines the flexibility of Agile methodologies, which include Scrum, XP, Kanban, and Lean, each catering to different contexts and fostering collaboration, efficiency, and quality. It stresses the necessity of choosing suitable methods rather than relying on a one-size-fits-all approach, and introduces governance-oriented methods for larger environments.
- 3.4: PMI-ACP Style Sample Questions
- This page discusses sample questions on Agile methodologies, highlighting the importance of choosing the right approach based on team needs and contexts. It covers key concepts like the use of Kanban for unpredictable work, iteration-based thinking for uncertain requirements, and fit-for-purpose agility. The implications of team dynamics, governance in Agile, and Lean thinking to reduce delays are explored, emphasizing the need for tailored Agile practices over a universal approach.
