What is Agile?
Agile is a term in the IT industry that describes principles. Both software development and project management follow these principles.
Agile practices are a collection of methodologies that demonstrate a commitment to short feedback cycles and continuous improvement.
That said, agile software development is more of an approach to a project and a mindset. Agile methodologies deliver work in small, manageable increments, allowing them to provide value to their customers.
Continuous evaluation of requirements, plans, and results enables teams to respond to changes faster.

How do Agile Practices Work?
According to the Agile manifesto, Agile practices are guidelines for transforming your project management processes. Your situation determines how you use them. Embracing agility is a never-ending process as solutions evolve, so you should always experiment to see what works best for your company.
To finish tasks on time, software development teams need a game plan. This is where agile methodologies come in handy. These agile methods include making lists, prioritizing projects, and assigning specific tasks.
Team members and experts meet and provide estimates for each feature, including the time required to complete architecture, development, and activities.
Teams break down one big planning phase and deliver it in smaller parts at different intervals. Agile teams create plans focusing on outcomes that provide customer value rather than outputs.
What is the Purpose of Agile?
Agile is an iterative approach to project management that divides product development work into small increments, reducing the amount of upfront planning and design. Iterations, also known as sprints, are short periods lasting one to four weeks.
The waterfall model was one of the most popular software development models for delivering any software project. However, software developers encountered numerous issues using the waterfall method to develop new software. There were flaws in the waterfall model that caused difficulties, including the time and cost required for changes.
Proposing the Manifesto for Agile Software Development processes addressed these shortcomings. Agile assists software development projects in adapting to the client’s and market’s changing requirements and provides quick project completion.
What are Examples of the Agile Methodology?
- Extreme Programming – allows teams to create high-quality software that improves lives. It allows for software development and appropriate product management and engineering practices. It’s useful when dealing with changing software requirements, risks associated with new software, working with a small, extended development team, and technology that allows automated unit and functional tests.
- The Kanban system – is an agile process used for designing, managing, and improving the flow of software systems. Kanban allows businesses to visualize their workflow and limit the amount of work in progress.
- Lean – is a set of tools and principles aimed at identifying and eliminating waste that accelerates process development. Almost every industry that generates waste somehow tries to minimize waste and maximize value.
- Scrum – is a framework that a team uses to develop a hypothesis, test it, reflect on the experience, and make changes. It allows teams to incorporate practices from other frameworks based on their needs. Cross-functional product development teams use scrum and divide their work into 2-4 week iterations.
- Crystal – prioritizes people and their interactions over tools and processes. Crystal works on the principle that agile approaches are unique and dynamic to streamline processes and improve optimization. Used when the emphasis is on improving team communication, continuous integration, active user participation, and configurable processes.
What are the Benefits of an Agile Approach?
Teams from various functional areas must collaborate to deliver successful projects and satisfy clients in Agile frameworks. This simplifies managers’ jobs and puts them in a better position to manage budgets and schedules.
Clients are not required to wait for results. Instead, their involvement is from the beginning. Even better, they get a lite version of the product in weeks. That’s more appealing than a developed product after a few years.
That said, the most crucial reason for the agile method is project delivery. Traditional waterfall methods take a long time to see a glimpse of the finished product.
Essential Features of Agile
Agile development follows a required set of principles in the software industry. These principles are essential features for successful agile methodologies.
- Customer satisfaction and surpassing customer expectations.
- Welcoming change and adjusting the development process.
- Frequent delivery by focusing on shorter time frames.
- Working together with other agile development teams.
- Team motivation and follow-up on team’s progress.
- Face-to-face meetings to discuss project management.
- Developing working software to demonstrate progress.
- Ensuring a consistent pace and continuous delivery.
- Having a clear design of developing software processes.
- Self-organizing teams and adapting to changes.
- Reflecting and adjusting based on popular agile methodologies.
How to Measure the Effectiveness of Agile Software
The organization develops a project vision, product roadmap, and business case before beginning an agile project. This includes gathering and prioritizing business and technical requirements, forming teams, and estimating time. On-time delivery is one of the best ways to measure the effectiveness of an agile project.
Quality of the Product
Quality presents in different ways, including customer satisfaction, revenue growth, and the technical aspects of testing performed throughout the development life cycle. Product quality represents an effective production process.
Measured by looking at sales figures, the number of support calls, and the amount of returning customers, customer satisfaction is essential in expanding any business.
Clear objectives, clear business goals, and stakeholder support are crucial elements that aid in the effectiveness of agile values.
Scope of the Product
Setting goals and tracking project status is rewarding, and real-time feedback on the work status benefits everyone on the team, from engineers to program managers. Understanding the scope of the product is a result of effective agile methodologies.
Transparency is one of the most effective ways to increase trust. This entails making plans public and making progress visible to all. Sharing progress across multiple dimensions provides information that makes sense from the perspective of all business stakeholders.
In an agile world, productivity is a measure of outcomes rather than output. So considering burnup for a product or based on value has a significant impact. A simple burnup of the number of stories or features over time is an excellent way to understand how much the team delivers.
The velocity trend is a popular metric for assessing predictability. This shows the completion of work at a sustainable pace, which on average, is over a three- to-four-month period. A fluctuating velocity may indicate a changing team, unpredictable work, or a team still adjusting to defining work small enough to complete in an iteration.
Continuous improvement – getting better – is a core tenet of all lean and agile mindsets. All the metrics mentioned above are useful, but there’s also the cumulative flow chart, which shows how well work flows through the lifecycle.
Advantages of Agile Software Development:
- Agile allows for significant interaction and collaboration between the client and the project team members.
- Clients benefit from increased transparency, and as a result, they better understand the project’s phases.
- On-time product delivery, or even earlier in some cases.
- The project’s cost is predictable.
- Changes have the potential to refine and re-prioritize the product backlog.
- Allows the client to prioritize various features, allowing the team to maximize project value.
- Smaller units allow for high-quality development, testing, and collaboration.
Agile methodologies enable us to see additional and intangible ways to improve an organization’s performance.
There is no single best practice to put in place, and call your team or company “Agile.” Instead, start with an Agile mindset and experiment to see what works best for you and your company.
