Definition
Agile is an approach to developing software and products in short, repeated cycles, delivering working increments frequently and adjusting priorities based on what is learned, rather than following a fixed plan set months in advance. It was defined in the 2001 Agile Manifesto, which values individuals and interactions, working software, customer collaboration and responding to change. Agile is a philosophy; frameworks such as Scrum and Kanban are specific ways to practise it.
In a company, agile means the product team ships something usable every 1 to 4 weeks, shows it to customers or stakeholders, and decides the next priorities from that feedback. Requirements are kept as a prioritised backlog rather than a frozen specification. Leaders set goals and constraints; teams decide how to reach them. The approach has spread from software to marketing, operations and even strategy, wherever uncertainty is high and learning fast pays.
Agile is now the default in software, and the debate has moved to how to keep it lean: many organisations found that heavy agile frameworks and ceremonies became their own bureaucracy. AI coding tools compress development cycles further, making fast feedback even more valuable. The misconception is that agile means no planning or no deadlines. It means planning continuously with real information, and committing to outcomes rather than to a fixed list of features.
In practice
Instead of a 12-month project to rebuild its customer portal, a company shipped a minimal version in 6 weeks to 50 pilot customers, then improved it every 2 weeks based on their usage. Half the originally planned features were never built because nobody needed them.
Why it matters
Agile is how you avoid spending a year building the wrong thing. For a CEO, it changes what you ask for: outcomes and regular demos, not a fixed feature list and a delivery date.
Frequently asked questions
- What is the difference between agile and waterfall?
- Waterfall plans the whole project up front and moves through fixed phases: requirements, design, build, test, release. Agile delivers small working pieces repeatedly and adjusts the plan as it learns. Waterfall suits work with stable, well-understood requirements; agile suits products where learning from users matters.
- What is the difference between agile and Scrum?
- Agile is the broad philosophy of iterative delivery and responding to change. Scrum is one specific framework for practising it, with defined roles, fixed-length sprints and set meetings. Kanban is another. A team can be agile without using Scrum.
