In the realm of project management, Agile isn’t merely a singular method but rather a flexible, overarching philosophy that has influenced a wide array of approaches such as Scrum, Kanban, and Lean. These methods, collectively known as Agile methodologies, share a common foundation built on Agile’s core principles of adaptability, collaboration, and continuous improvement.
For businesses and teams aiming to implement Agile effectively, it’s crucial to grasp its core principles and balance its benefits and challenges. But what sets Agile apart as a critical framework in today’s project management landscape? Let’s dive deeper into why Agile has become a fundamental strategy for modern businesses.
Agile, short for Agile Software Development, is a flexible software development approach characterized by brief, iterative cycles lasting 1 to 4 weeks. The primary goal of Agile is to shorten product development time and deliver working products to customers as quickly as possible.
At its core, Agile is more of a methodology or philosophy based on iterative and incremental development principles, providing high flexibility. This approach contrasts with traditional project management methods, which often implement stages linearly and struggle to adapt to unexpected changes.
Today, Agile's philosophy has extended beyond software development to influence working methods, management, and production in other sectors such as manufacturing, services, sales, marketing, and education. It has become one of the most popular project management methods today, represented by various “Agile families.”
Before Agile emerged, the Waterfall model was considered the standard for software development. Typically, the process began with a business analyst drafting a lengthy, detailed requirement document outlining all specifications. After completing these documents, developers would start coding, finishing, and testing the software. This entire process could take years before the software was ready for use.
The development landscape began to shift with the rise of the Internet, which exposed the inefficiencies of the Waterfall method. It consumed too much time and effort and often lacked practicality, as it relied heavily on research without real-time user feedback.
In 2001, a group of 17 experienced software developers, including Kent Beck, Martin Fowler, Ron Jeffries, Ken Schwaber, and Jeff Sutherland, collaborated to create and publish the Agile Manifesto. This manifesto outlined four fundamental values and 12 guiding principles focusing on a people-centric, iterative approach to software development. The Agile Manifesto represents their belief in the ideal operational process for modern software development.
The Agile Manifesto emphasizes collaboration, adaptability, and continuous improvement, moving away from rigid methods and cumbersome documentation associated with traditional Waterfall models.
Iterative process
Projects are divided into repeating segments, usually lasting 1-4 weeks. Each segment involves all necessary tasks, such as planning, requirement analysis, design, implementation, and testing, to produce small parts of the final product.
Incremental and evolutionary development
At the end of each segment, a small part of the final product is delivered, fully functional, carefully tested, and ready for use. Over time, these segments build upon each other until the customer’s complete requirements are met.
Adaptability
Because each segment lasts a short time and plans are constantly adjusted, changes during development (e.g., changes in requirements, technology, or project goals) can be accommodated effectively.
Self-organizing and cross-functional teams
Agile teams organize their work without rigid job descriptions or clear hierarchies. These teams are empowered to make decisions, manage themselves, and organize their work for maximum effectiveness.
Empirical process control
Agile teams make decisions based on real-world data (data-driven) rather than theoretical calculations or assumptions. Agile shortens feedback loops, making adapting and increasing flexibility easier, thus improving process control and productivity.
Face-to-face communication
While Agile does not oppose documentation, it values direct communication over paperwork. It encourages development teams to engage in direct conversations to understand better what customers truly need. Agile promotes direct exchanges and consensus on system design within the team, working together to implement required functionalities.
Value-based development
A fundamental principle of Agile is that “working software is the primary measure of progress.” Agile teams frequently collaborate with customers to prioritize high-value requirements and deliver value as soon as possible.
In the past, product development teams often focused on the best tools and processes for building a product. While these are important, Agile asserts that the people behind the processes are the most crucial factor.
Having the right individuals on the team is the key to success. The best tools become useless in the hands of incapable people. Furthermore, interaction and connection among team members are vital to effective teamwork and problem-solving.
Previously, software engineers would spend a lot of time drafting detailed documents on product design and specifications before starting to code. While comprehensive documentation is a plus, focusing on delivering a working product is more important.
The Agile Manifesto prioritizes providing a practical product to the customers above all else.
In other methods, project owners draft contracts first, and then customers complete the detailed picture of the required product. This often leads to discrepancies between what the contract states, what the product can do, and what the customer truly needs.
Agile emphasizes continuous development, creating an iterative feedback loop with customers to ensure the product meets their needs.
We often aim to create a perfect project roadmap with no deviations, but that rarely happens. The implementation process will always bring up new issues not foreseen in the plan, and customer needs and requirements will continuously change.
The Agile Manifesto requires teams to be able to pivot and change direction at any time, with a flexible roadmap that adapts weekly, monthly, or quarterly.
Agile is increasingly popular among businesses for its advantages over traditional methods:
Despite its advantages, Agile also offers some challenges:
There are many variables from the original Agile methodology, with Scrum being the most popular. Project managers also create combined methods like Scrumban, which means Scrum + Kanban.
Let’s explore some of the most common Agile methodologies in more detail.
As the most popular Agile methodology, Scrum is often confused with Agile itself.
Scrum operates on iterative and incremental mechanisms, allowing project teams to focus on optimizing value within fixed timeframes. A standout feature of Scrum is the Sprint development cycles, which aim to maximize product development time to achieve Product Goals.
Scrum is built on three core principles: Transparency, Inspection, and Adaptation, making it a favored choice for managers looking to enhance team performance.
Kanban, originating from Japan and first used at Toyota, is a term that combines “kan” (visual) and “ban” (card), translating to “visual card.”
Kanban organizes tasks on a visual board divided into columns representing different stages in the project workflow. A simple Kanban board might start with three columns: To-do, Doing, and Done. As tasks progress, the information on the board changes continuously. New tasks are added as cards.
Kanban emphasizes absolute communication and transparency, ensuring all team members can identify the project's current stage and status.
Lean is a management model based on the philosophy of minimizing waste while maximizing productivity. It originated in manufacturing and is now widely applied across various industries.
Lean's five essential principles include:
Extreme Programming (XP) is an Agile framework that can be adjusted to suit different company sizes. XP operates on the idea of finding "the simplest thing that could possibly work" without investing too much effort in long-term visions for the product.
This method prioritizes customer satisfaction above all else and emphasizes trust by accepting changes in customer requirements, even late in the development cycle.
Teamwork is also crucial in XP, as issues are resolved by the entire management team, software engineers, and customers. They are all essential parts of the XP process.
Crystal is the most flexible Agile framework, offering teams freedom in development. It emphasizes individuals and their interactions over processes and tools.
Crystal focuses on principles such as People, Interaction, Community, Skills, Talent, and Communication, aiming to deliver the best possible development process.
According to its founder, "Crystal is a group of software development methods that leverage human power, are extremely lightweight, and can be stretched to fit."
Crystal has various versions, including:
Agile is a highly applicable product development model, suitable for projects requiring flexibility, high complexity, or uncertainty.
However, not all businesses are suited for Agile. Successful implementation requires certain prerequisites:
Notably, some businesses have adopted Agile for 5-7 years but remain stuck in an “old wine in a new bottle” situation. This isn’t surprising because while Agile might seem easy to understand, mastering it is difficult, especially in large organizations. Agile focuses heavily on human factors, including culture, communication, teamwork, and collaboration among stakeholders, and changing culture and human behavior is never easy.
Businesses might consider hiring a skilled Agile coach to address this. Depending on needs, coaching can take 3-12 months or longer.
A complete Agile process
Phase 1: Ideation and project roadmap
Every product development project begins with defining the vision, ideation, and roadmap, involving all stakeholders: software engineers, investors, and anyone else with product knowledge.
For example, in the Scrum model, the execution team carries out the following tasks during the initial phase:
This phase is crucial because it determines the project's initial scope. Since Agile follows an iterative process with continuous cycles, teams must keep initial requirements minimal and gradually add new features during later development stages.
Phase 2: Planning
After ideation, software engineers organize their tasks into iterations (Sprints), analyze customer requirements to refine the Product Backlog and build the product's first version.
The development phase varies depending on the type of product being developed. This is typically the longest stage in the Agile model, where most work is done. The core goal for the execution team during this phase is to build functional parts of the product at the end of each Sprint.
Phase 3: Project deployment
In Agile, the deployment phase depends heavily on what the team has created in previous phases. The team must understand where and how the product will be deployed.
Phase 4: Testing
Testing activities occur throughout Agile implementation. Before releasing the product, it must undergo all necessary tests and quality assurance processes to ensure it’s fully functional.
Phase 5: Product delivery and maintenance
In the final phase, after delivering the product to the customer at the end of a Sprint, the project team focuses on ongoing maintenance, resolving issues, and ensuring the product remains functional and efficient.
Many issues arise when users interact with the product, so the team may need to address some feature bugs or performance issues. However, this also allows the team to gather feedback and apply new improvements in subsequent Agile iterations.
The adoption of Agile in business operations and project management has allowed companies to save considerable time and resources as its approach makes identifying and addressing issues easier than ever before.
However, implementing Agile is not straightforward; it heavily relies on leadership's flexibility and adaptability. Introducing Agile into a company is not just a project but a significant transformation that impacts company culture and human resource strategies. Agile demands a shift in business operations, requiring leaders to embrace continuous change and foster an environment that supports collaboration, autonomy, and rapid feedback cycles.
