Agile methodologies have revolutionised the world of software development, offering a flexible and collaborative approach to project management. At the core, these methodologies all focus on delivering value to customers through iterative and incremental development, emphasising customer feedback, and adapting to changing requirements. Scrum is just one flavour of agile methodology, though arguably the most widely adopted framework. In this article we’ll explore the pros and cons of adopting Scrum as an agile framework, briefly contrast it with another popular framework, and provide tips for those considering its adoption.
What is Scrum?
Scrum is a well-established agile framework designed to tackle complex problems efficiently. It’s founded on key principles like transparency, inspection, and adaptation. Scrum involves specific roles, ceremonies, and artefacts that structure the development process:
- Roles: Scrum defines three essential roles – the Product Owner, responsible for defining product goals and prioritising the backlog; the Scrum Master, who ensures the team adheres to Scrum practices and removes impediments; and the Development Team, responsible for delivering the product.
- Ceremonies: Scrum organises the development process through ceremonies, including Sprint Planning (defining goals for the upcoming sprint), Daily Scrum (brief daily meetings to discuss progress), Sprint Review (showcasing the work done during the sprint to stakeholders), and Sprint Retrospective (reflecting on the sprint and identifying areas for improvement).
- Artefacts: Scrum employs various artefacts, such as the Product Backlog (a prioritised list of features and requirements), the Sprint Backlog (the subset of items the team commits to completing in a sprint), and the Increment (the product’s potentially shippable version).
Scrum vs Kanban
Kanban is an extensively used agile framework. It offers a primarily visual approach to managing work, consisting of Kanban boards ‘To do’, ‘In progress’ and ‘Done’ which visually allow for task prioritisation and identification of bottlenecks.
Kanban is a less structured framework than Scrum. For example, the intervals for sections of work are not pre-defined. In Scrum, teams work in sprints, which are short, iterative cycles of development. Each sprint typically lasts two to four weeks. In Kanban, teams do not have to work in sprints. They can work on tasks as they are ready to be worked on.
Another way that Kanban is less structured is that the prioritisation of work is not built into the framework, it’s rather more implicitly defined depending on the nature of the project.
The lack of structure in Kanban can be a benefit for teams that are working on complex or ill-defined projects. It allows teams to be flexible and adapt to change. However, the lack of structure can also be a challenge for teams that are not used to working in a self-directed way. For projects that have more definition, and aren’t expected to change frequently, Scrum is often the preferred choice.

Pros of Scrum
Let’s continue our foray into Scrum primarily. Here are some of the key advantages that we see Scrum providing software development teams:
Scrum Accelerates Software Delivery
Scrum’s iterative approach accelerates software delivery by breaking the project into smaller, manageable cycles. This allows for rapid development and frequent releases, ensuring that valuable features reach users sooner. It’s an intrinsic bedfellow of dev-ops.
Fostering Teamwork, Communication, and Transparency
Scrum emphasises collaboration among team members and stakeholders. Daily Scrum meetings encourage communication, while transparency through artefacts like the Product Backlog and Sprint Backlog ensures everyone is aligned and informed.
Reduced Documentation Overhead
Scrum prioritises working software over comprehensive documentation, reducing administrative overhead and saving costs.

Cons of Scrum
Every rose has it’s thorn, and Scrum is not without its challenges. Here’s an overview of what we consider to be the key ‘cons’ to adoption of Scrum.
Complexity in Implementation
Implementing Scrum effectively can be complex, often requiring skilled Scrum Masters who understand the framework’s intricacies.
Lack of Detailed Project Planning
Scrum prioritises working software over comprehensive documentation, potentially leading to a lack of detailed project planning. This can be challenging in projects with strict regulatory or compliance requirements.
Active Involvement Required
Scrum relies on active involvement from all team members and stakeholders. This can be challenging in organisations where team members have diverse responsibilities and commitments.
Difficulties in Larger Organisations
Scrum’s self-organising nature is more suitable for smaller teams, which can pose challenges when scaling up for larger projects or organisations.
Teething Issues in Agile Adoption
When organisations embark on the journey of adopting agile methodologies like Scrum, they often encounter a series of challenges that can act as initial hurdles. Successful Scrum adoption relies heavily on a few critical factors:
Proper Training and Team Commitment
Agile methodologies, including Scrum, require a deep understanding of their principles, practices, and nuances. Teams need appropriate training to grasp these concepts fully. Furthermore, a strong commitment to the agile mindset is essential. Team members must embrace collaboration, adaptability, and a focus on delivering value to customers.
Shifting Organisational Structure
Agile methodologies advocate a shift from traditional hierarchical structures to more collaborative and cross-functional teams. This can be a significant cultural shift for organisations accustomed to top-down decision-making. Teams need to adapt to self-organisation and embrace shared responsibilities.
Managing Scope and Budget
With short, iterative sprint cycles, it can become more challenging to manage project scope and budget. Properly defining and controlling scope becomes a critical aspect of agile project management.

Tips for Scrum adoption
Here are some tips for adopting Scrum, particularly in larger teams:
1) Start small
Don’t try to adopt agile all at once. Start with a small pilot project and learn from your experiences.
2) Get buy-in from stakeholders
Make sure that all stakeholders are on board with the new approach. This includes managers, customers, and other team members.
3) Invest in training
Make sure that everyone on the team is trained in the Scrum methodology. This will help to ensure that everyone is on the same page.

In conclusion, Scrum offers numerous advantages, including accelerated software delivery, improved teamwork, and reduced documentation overhead. However, it comes with challenges such as complexity in implementation, potential lack of detailed project planning, and the need for active involvement from all team members. Successful Scrum adoption requires careful consideration and proper training to harness its benefits effectively.
