Agile Development – Definition, Use Cases and Best Practices at a Glance
Iterative approach to software development with short cycles, regular feedback and continuous improvement – instead of rigid planning and long waterfall phases.
What is Agile Development? Methods, Benefits & Practical Tips
Agile development has fundamentally changed the software industry. Instead of long planning phases and rigid specification structures, the agile approach uses short development cycles, close collaboration with the customer and willingness to adapt to change. Since the Agile Manifesto in 2001, this approach has become the de facto standard for professional software development.
This glossary entry for Agile Development gives you a clear Definition, practical Use Cases and Best Practices at a glance – with examples, pros and cons, and FAQs.
What is Agile Development?
- Agile Development – Iterative approach to software development with short cycles, regular feedback and continuous improvement – instead of rigid planning and long waterfall phases.
Agile development is an umbrella term for methods and frameworks (Scrum, Kanban, XP) that develop software iteratively in short cycles (sprints).
At its heart is the Agile Manifesto with four values: individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan.
Instead of specifying everything up front, working increments are delivered in iterations of 1–4 weeks, reviewed and commented on by the customer. The result is software that actually meets needs – not an outdated specification.
How does Agile Development work?
An agile project starts with a vision and a prioritised product backlog – a list of requirements (user stories) ordered by business value. In each sprint (typically 2 weeks) the team selects the most important stories and turns them into working software. At the end of the sprint the result is shown to the customer in the sprint review.
In the retrospective the team reflects on its process and identifies improvements. The product owner continuously reprioritises the backlog based on feedback, market changes and new insights. The project can change direction at any time without major replanning.
Practical Examples
A startup builds an MVP in 4 sprints, tests with early adopters and adjusts the roadmap based on real user feedback – instead of developing in isolation for 6 months.
A mid-size company modernises its ERP step by step: each sprint delivers a working module that can be used in production while the old system continues in parallel.
An e-commerce company improves its shop in weekly releases based on A/B tests and user data – agile and data-driven.
A healthcare company develops a patient app iteratively with doctors and patients as reviewers in every sprint review.
Typical Use Cases
Product development with unclear or changing requirements where flexibility is critical
MVP development for startups that need to test and learn in the market quickly
Continuous evolution of existing software based on user feedback
Digitalisation projects in mid-size companies where stakeholders are brought in step by step
Complex integration projects where technical risks are validated early with prototypes
Advantages and Disadvantages
Advantages
- Higher customer satisfaction through regular feedback and involvement in development
- Faster time-to-market: working software from the first sprint instead of after months
- Risk reduction through early validation and course correction in every iteration
- Higher team productivity and motivation through self-organisation and clear ownership
- Better software quality through continuous testing and refactoring
Disadvantages
- Requires active customer involvement – if unavailable, outcome quality suffers
- Scope control can be challenging when new requirements keep appearing
- Harder with fixed-price projects as total effort is less predictable up front
- Requires experienced, self-organising teams – less suitable for developers without agile experience
Frequently Asked Questions about Agile Development
What is the difference between Scrum and Kanban?
Scrum works in fixed sprints (typically 2 weeks) with defined roles (Product Owner, Scrum Master, Team) and events. Kanban is more fluid – work is visualised on a board and controlled by WIP limits. Scrum suits product development with planned releases; Kanban suits support, maintenance and continuous improvement.
Is agile development suitable for large projects too?
Yes. Frameworks like SAFe (Scaled Agile Framework), LeSS and Nexus scale agile for large organisations with many teams. The overall project is split into smaller, independent streams that work agile and sync regularly. A clear architecture vision and good communication between teams are important.
What does an agile software project cost?
Agile projects are typically billed by effort (time & materials) rather than fixed price. A sprint team (3–5 developers, Product Owner, Scrum Master) costs roughly €15,000–40,000 per sprint depending on seniority. The benefit: you can change direction, reprioritise or stop when the desired value is achieved.

Agile Development in the Context of Modern IT Projects
This page provides a concise definition of Agile Development, practical use cases and best practices at a glance — everything you need to evaluate the technology for your next project. Agile Development falls within the domain of Methods and plays a significant role across a wide range of IT projects. When evaluating whether Agile Development is the right fit, organizations should look beyond the technical merits and consider factors such as existing team expertise, current infrastructure, long-term maintainability, and total cost of ownership.
Drawing on our experience from over 250 software projects, we have found that correctly positioning a technology or methodology within the broader project context often matters more than its isolated strengths.
At Groenewold IT Solutions, we have worked with Agile Development across multiple client engagements and understand both its advantages and the typical challenges that arise during adoption. If you are unsure whether Agile Development suits your particular requirements, we are happy to provide an honest, no-obligation assessment. We analyze your specific situation and recommend the approach that delivers the most value — even if that means suggesting an alternative solution.
For more terms in the area of Methods and related topics, see our IT Glossary. For concrete applications, costs, and processes we recommend our service pages and topic pages — there you will find many of the concepts explained here put into practice.
