Agile is not a tool or a daily meeting. It is a way of managing work through small, frequent deliveries, learning from each one and changing the plan when reality changes. People who look it up usually want three answers: what Agile is, how it differs from Scrum, and which certificate to start with — often framed as PMI-ACP vs Scrum Master. The short version: Agile is the philosophy, Scrum is one framework that applies it, and the PMI-ACP from the Project Management Institute (PMI) tests your grasp of Agile across all its frameworks, not of Scrum alone.
What is the Agile methodology?
Agile was born in the "Manifesto for Agile Software Development" of 2001, a short text written by developers who wanted an alternative to long plans that never changed. It rests on four values, each preferring one thing over another:
- Individuals and interactions over processes and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
The manifesto itself says the items on the right still have value, but the items on the left are valued more. Agile does not abolish plans or documents; it puts them in the service of the goal.
The twelve principles in brief
Twelve principles accompany the manifesto. The ones that matter most outside software: the highest priority is satisfying the customer through early and continuous delivery of something valuable; changing requirements are welcome, even late; delivery is frequent, from a couple of weeks to a couple of months, preferring the shorter timescale; business people and the team work together daily; and at regular intervals the team reflects on how it works and adjusts. These principles are why Agile fits marketing, digital transformation and service design projects, not just software.
What is Scrum?
The Scrum Guide describes Scrum as a lightweight framework that helps teams generate value through adaptive solutions for complex problems. It is written in one short, free guide and defines three things:
Three accountabilities within the Scrum Team:
- Product Owner: accountable for maximising the value of the product and for ordering the backlog.
- Scrum Master: accountable for establishing Scrum as the guide defines it and for the team's effectiveness.
- Developers: the people who create the usable increment each Sprint, whatever their speciality.
The team is small, typically 10 or fewer people, with no sub-teams or hierarchies inside it.
Five events: the Sprint itself, a fixed length of one month or less; Sprint Planning; the Daily Scrum, a 15-minute event; the Sprint Review with stakeholders; and the Sprint Retrospective, where the team inspects how it works.
Three artifacts: the Product Backlog, the Sprint Backlog and the Increment, which must meet the "Definition of Done".
Agile vs Scrum: the difference
The two are confused because Scrum is often spoken of as if it were a synonym for Agile. The difference in one line: Agile says why and by which values; Scrum says how, with specific rules.
- Agile is a philosophy: four values and twelve principles, with no prescribed roles or meetings.
- Scrum is a framework: roles, events and artifacts with defined names and timeboxes. Its guide says you can implement parts of it, but the result is not Scrum.
- Agile is wider: it includes approaches other than Scrum, among them Lean and Kanban, and the PMI-ACP page names them all.
So when you hear that a team "does Agile", the right question is: with which framework? When you hear it "does Scrum", it is doing Agile in one specific way.
What is the PMI-ACP certification?
The PMI Agile Certified Practitioner (PMI-ACP) is awarded by PMI, and its official page describes it as framework-agnostic: it covers Scrum, Lean, Kanban and more. The page lists who it serves: product owners, Scrum masters, Agile team leads, developers, project managers, Agile coaches and product managers.
The PMI-ACP exam at a glance
- 120 multiple-choice questions in 180 minutes, with one 10-minute break.
- Offered in ten languages, including Arabic.
- Taken at a Pearson VUE test centre, which PMI recommends, or online after a system test and ID check.
- Questions are spread across four domains: Mindset 28%, Leadership 25%, Product 19% and Delivery 28%.
- If you do not pass, you have three attempts within one year.
- To keep the certificate you earn 30 professional development units (PDUs) in each three-year cycle.
The page quotes no fixed fee: you pay the exam fee once your application is accepted, and the amount appears in your PMI account.
PMI-ACP eligibility requirements
The certification page sets three requirements:
- Education: a secondary school diploma or equivalent, or higher.
- Agile experience, by one of four routes: two years of Agile experience in the past five years; a degree from a GAC-accredited programme plus one year of experience; a third-party Agile certification plus one year of experience; or the PMP certification.
- Training: 21 hours of formal training in Agile practices and frameworks, from PMI's own prep course, a course with one of its training partners, or third-party training courses.
Note that a PMP holder meets the experience requirement outright. That is why many people make the PMI-ACP their second step after the PMP; if that is your plan, read our guide to the PMP exam.
PMI-ACP vs Scrum Master: which certificate first?
"Agile Scrum certification" is a common search, and the answer depends on your work:
- If your role is to lead one team that works in Scrum, a Scrum Master certification from the bodies that specialise in that framework focuses on what you will do every day.
- If you manage projects or products across different teams and frameworks, or work in a hybrid setting that mixes traditional planning with Agile, the PMI-ACP is broader because it does not test a single framework.
- If you already have two years of Agile experience or the PMP, you meet the experience requirement today.
The two paths do not compete: PMI's page accepts a third-party Agile certification plus one year of experience as a route to the experience requirement. For structured preparation for the PMI-ACP exam, see the Agile programme; if you are asking about funding, read our article on HRDF support for professional certificates.
Frequently asked questions
What is the Agile methodology, briefly?
A way of managing work built on small, frequent deliveries, continuous collaboration with the customer and changing the plan when reality changes. It rests on the four values and twelve principles of the 2001 Agile Manifesto.
What is the difference between Agile and Scrum?
Agile is a philosophy of values and principles; Scrum is a specific framework that applies it, with three accountabilities, five events and three artifacts. Everyone doing Scrum is doing Agile, but not the other way round.
What is the PMI-ACP certification?
PMI's Agile Certified Practitioner credential, which tests your understanding of Agile across its different frameworks rather than one. The exam is 120 questions in 180 minutes.
Is the PMI-ACP exam available in Arabic?
Yes. Arabic is one of the ten languages the exam is offered in, according to PMI's certification page.
What are the PMI-ACP requirements?
A secondary school diploma or higher; Agile experience (two years within five, or one year with a GAC-accredited degree or another Agile certification, or the PMP); and 21 hours of Agile training.
Do I need the PMP before the PMI-ACP?
No, the PMP is not a prerequisite. It is one of the routes to the experience requirement, so a PMP holder does not need to show two years of Agile experience.
