What is Agile Methodology?

Agile Methodology meaning a practice that promotes continuous iteration of development and testing throughout the software development lifecycle of the project. In the Agile model in software testing, both development and testing activities are concurrent, unlike the Waterfall model.

What is Agile Software Development?

The Agile software development methodology is one of the simplest and effective processes to turn a vision for a business need into software solutions. Agile is a term used to describe software development approaches that employ continual planning, learning, improvement, team collaboration, evolutionary development, and early delivery. It encourages flexible responses to change.

The agile software development emphasizes on four core values.

  1. Individual and team interactions over processes and tools
  2. Working software over comprehensive documentation
  3. Customer collaboration over contract negotiation
  4. Responding to change over following a plan

The agile software development emphasizes on four core values.

In this Agile project management tutorial, you will learn-

Agile Model Vs Waterfall Model

Agile and Waterfall model are two different methods for software development process. Though they are different in their approach, both methods are useful at times, depending on the requirement and the type of the project.

Agile Model

Waterfall Model

  • Agile methodology definition: Agile methodologies propose incremental and iterative approach to software design
  • Waterfall Model: Development of the software flows sequentially from start point to end point.
  • The Agile process in software engineering is broken into individual models that designers work on
  • The design process is not broken into an individual models
  • The customer has early and frequent opportunities to look at the product and make decision and changes to the project
  • The customer can only see the product at the end of the project
  • Agile model is considered unstructured compared to the waterfall model
  • Waterfall model are more secure because they are so plan oriented
  • Small projects can be implemented very quickly. For large projects, it is difficult to estimate the development time.
  • All sorts of project can be estimated and completed.
  • Error can be fixed in the middle of the project.
  • Only at the end, the whole product is tested. If the requirement error is found or any changes have to be made, the project has to start from the beginning
  • Development process is iterative, and the project is executed in short (2-4) weeks iterations. Planning is very less.
  • The development process is phased, and the phase is much bigger than iteration. Every phase ends with the detailed description of the next phase.
  • Documentation attends less priority than software development
  • Documentation is a top priority and can even use for training staff and upgrade the software with another team
  • Every iteration has its own testing phase. It allows implementing regression testing every time new functions or logic are released.
  • Only after the development phase, the testing phase is executed because separate parts are not fully functional.
  • In agile testing when an iteration end, shippable features of the product is delivered to the customer. New features are usable right after shipment. It is useful when you have good contact with customers.
  • All features developed are delivered at once after the long implementation phase.
  • Testers and developers work together
  • Testers work separately from developers
  • At the end of every sprint, user acceptance is performed
  • User acceptance is performed at the end of the project.
  • It requires close communication with developers and together analyze requirements and planning
  • Developer does not involve in requirement and planning process. Usually, time delays between tests and coding

Agile Process

Check the below Agile methodology process to deliver successful systems quickly.

Agile Process Model

Agile Process Model

There are various Agile methods present in agile testing, and those are listed below:


SCRUM is an agile development method which concentrates specifically on how to manage tasks within a team-based development environment. Basically, Scrum is derived from activity that occurs during a rugby match. Scrum believes in empowering the development team and advocates working in small teams (say- 7 to 9 members). Agile and Scrum consist of three roles, and their responsibilities are explained as follows:

Scrum Method

Scrum Method

  • Scrum Master

    • Master is responsible for setting up the team, sprint meeting and removes obstacles to progress

  • Product owner

    • The Product Owner creates product backlog, prioritizes the backlog and is responsible for the delivery of the functionality at each iteration

  • Scrum Team

    • Team manages its own work and organizes the work to complete the sprint or cycle

Product Backlog

This is a repository where requirements are tracked with details on the no of requirements(user stories) to be completed for each release. It should be maintained and prioritized by Product Owner, and it should be distributed to the scrum team. Team can also request for a new requirement addition or modification or deletion

Scrum Practices

Practices are described in detailed:

Scrum Practices

Scrum Practices

Process flow of Scrum Methodologies:

Process flow of scrum testing is as follows:

  • Each iteration of a scrum is known as Sprint

  • Product backlog is a list where all details are entered to get the end-product

  • During each Sprint, top user stories of Product backlog are selected and turned into Sprint backlog

  • Team works on the defined sprint backlog

  • Team checks for the daily work

  • At the end of the sprint, team delivers product functionality

Extreme Programming (XP)

Extreme Programming technique is very helpful when there is constantly changing demands or requirements from the customers or when they are not sure about the functionality of the system. It advocates frequent “releases” of the product in short development cycles, which inherently improves the productivity of the system and also introduces a checkpoint where any customer requirements can be easily implemented. The XP develops software keeping customer in the target.

Extreme Programming

Extreme Programming

Business requirements are gathered in terms of stories. All those stories are stored in a place called the parking lot.

In this type of methodology, releases are based on the shorter cycles called Iterations with span of 14 days time period. Each iteration includes phases like coding, unit testing and system testing where at each phase some minor or major functionality will be built in the application.

Phases of eXtreme programming:

There are 6 phases available in Agile XP method, and those are explained as follows:


  • Identification of stakeholders and sponsors

  • Infrastructure Requirements

  • Security related information and gathering
  • Service Level Agreements and its conditions


  • Capturing of Stories in Parking lot

  • Prioritize stories in Parking lot

  • Scrubbing of stories for estimation

  • Define Iteration SPAN(Time)

  • Resource planning for both Development and QA teams


  • Break down of tasks

  • Test Scenario preparation for each task

  • Regression Automation Framework


  • Coding

  • Unit Testing

  • Execution of Manual test scenarios

  • Defect Report generation

  • Conversion of Manual to Automation regression test cases

  • Mid Iteration review

  • End of Iteration review


  • Small Releases

  • Regression Testing

  • Demos and reviews

  • Develop new stories based on the need

  • Process Improvements based on end of iteration review comments


  • Pilot Launch

  • Training

  • Production Launch

  • SLA Guarantee assurance

  • Review SOA strategy

  • Production Support

There are two storyboards available to track the work on a daily basis, and those are listed below for reference.

  • Story Cardboard

    • This is a traditional way of collecting all the stories in a board in the form of stick notes to track daily XP activities. As this manual activity involves more effort and time, it is better to switch to an online form.

  • Online Storyboard

    • Online tool Storyboard can be used to store the stories. Several teams can use it for different purposes.

Crystal Methodologies

Crystal Methodology is based on three concepts

  1. Chartering: Various activities involved in this phase are creating a development team, performing a preliminary feasibility analysis, developing an initial plan and fine-tuning the development methodology

  2. Cyclic delivery: The main development phase consists of two or more delivery cycles, during which the

    1. Team updates and refines the release plan
    2. Implements a subset of the requirements through one or more program test integrate iterations
    3. Integrated product is delivered to real users
    4. Review of the project plan and adopted development methodology
  3. Wrap Up: The activities performed in this phase are deployment into the user environment, post- deployment reviews and reflections are performed.

Dynamic Software Development Method (DSDM)

DSDM is a Rapid Application Development (RAD) approach to software development and provides an agile project delivery framework. The important aspect of DSDM is that the users are required to be involved actively, and the teams are given the power to make decisions. Frequent delivery of product becomes the active focus with DSDM. The techniques used in DSDM are

  1. Time Boxing
  2. MoSCoW Rules
  3. Prototyping

The DSDM project consists of 7 phases

  1. Pre-project
  2. Feasibility Study
  3. Business Study
  4. Functional Model Iteration
  5. Design and build Iteration
  6. Implementation
  7. Post-project

Feature Driven Development (FDD)

This method is focused around “designing & building” features. Unlike other Agile methods in software engineering, FDD describes very specific and short phases of work that has to be accomplished separately per feature. It includes domain walkthrough, design inspection, promote to build, code inspection and design. FDD develops product keeping following things in the target

  1. Domain object Modeling
  2. Development by feature
  3. Component/ Class Ownership
  4. Feature Teams
  5. Inspections
  6. Configuration Management
  7. Regular Builds
  8. Visibility of progress and results

Lean Software Development

Lean software development method is based on the principle “Just in time production”. It aims at increasing speed of software development and decreasing cost. Lean development can be summarized in seven steps.

  1. Eliminating Waste
  2. Amplifying learning
  3. Defer commitment (deciding as late as possible)
  4. Early delivery
  5. Empowering the team
  6. Building Integrity
  7. Optimize the whole


Kanban originally emerged from Japanese word that means, a card containing all the information needed to be done on the product at each stage along its path to completion. This framework or method is quite adopted in software testing method especially in Agile concepts.

Scrum Vs Kanban



  • In scrum technique, test must be broken down so that they can be completed within one sprint
  • No particular item size is prescribed
  • Prescribes a prioritized product backlog
  • Prioritization is optional
  • Scrum team commits to a particular amount of work for the iteration
  • Commitment is optional
  • Burndown chart is prescribed
  • No particular item size is prescribed
  • Between each sprint, a scrum board is reset
  • A Kanban board is persistent. It limits the number of items in workflow state
  • It cannot add items to ongoing iteration
  • It can add items whenever capacity is available
  • WIP limited indirectly
  • WIP limited directly
  • Timeboxed iterations prescribed
  • Timeboxed iterations optional

Agile metrics:

Metrics that can be collected for effective usage of Agile is:

  • Drag Factor

    • Effort in hours which do not contribute to sprint goal

    • Drag factor can be improved by reducing number of shared resources, reducing the amount of non-contributing work

    • New estimates can be increased by percentage of drag factor -New estimate = (Old estimate+drag factor)

  • Velocity

    • Amount of backlog(user stories) converted to shippable functionality of sprint

  • No of Unit Tests added

  • Time interval taken to complete daily build

  • Bugs detected in an iteration or in previous iterations

  • Production defect leakage

What are the Best Agile Project Management Tools?

Agile Project Management demands a flexible tool that enables you to track progress with Kanban boards and Burn charts but also offers a place to manage tasks and share documents. Based on that, we recommend the following popular Agile tools:

Know all about the 12 principles of Agile Manifesto in Agile Project Management.
Watch our video on “ 4 Values of Agile Manifesto Explained “ here: https://youtu.be/gf7pBZxOCtY
In this video, you’ll find answers to all the questions related to the 12 Agile Principles such as:
What are the 12 Agile Principles?
What are the principles in Agile Manifesto?
What are the 12 principles of Agile Methodology, etc.
Here are the 12 Principles of Agile Manifesto:
1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2.Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout the project.
5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
6. The most efficient and effective method of conveying information to and within a development team is a facetoface conversation.
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicitythe art of maximizing the amount of work not doneis essential.
11. The best architectures, requirements, and designs emerge from selforganizing teams.
12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly

Football This is St James Park: home of Newcastle United Football Club. I was born in Newcastle, and grew up a few miles out of town. In Newcastle, they say that football isn’t life and death: it’s more important than that. Alas, my football skills were sadly lacking. But there was this game we’d play in class when the teacher wasn’t looking. Football. Kind of. I’m sketchy on the rules; I guess we’d take turns to get across the pitch to score a goal. Agile Analogy It struck me recently that the game is a rather lovely demonstration of Agile: We have value delivered in small increments as the “ball” makes its way up the pitch. And we have the opportunity to “course correct”: it’s easy to recover from a wayward first \”kick\”. Special Pencil Hold on a second. I think I’ve just figured out how to play this game. Where did I put my special pencil Ah here it is, My turn: Ready. Aim. Aim some more. Fire! I mean: Shoot! As I’m sure you’ve guessed, this bigass pencil represents a Waterfall Approach. It’s an eggs in one basket approach: we design, build and test this leviathan. And launch it into the world. It’s either a big hit. Or it’s a big miss. No second chances. If our aim is true. If the playing field is flat. If the goalposts don’t move. We’re on to a winner. For me, that’s an awful lot of “ifs”. An awful lot of RISK. In an uncertain world, the big asspencil starts to look less like an unfair advantage, and more like an enormous liability. In an uncertain world, we need a pencil that’s more…what a good word here Agile. With this small but perfectly formed Agile pencil: our aim doesn’t have to be true. The playing field doesn’t need to be flat. The goal posts don’t need to stay put. All we have to do, is keep kicking. Can you do better So what did you make of the What is Agile pencil analogy Perhaps you hated it.You thought that it didn’t work at all. Perhaps you really liked it, and are wondering where you can your hands on an enormous pencil. Either way, I’d like your help with something I’m planning: I’m on a mission to collect the best “Agile Analogies”. So if you have a good one… or have heard of a good one… or can think of a good one Please let me know. If it helps to answer the question: “What is Agile ” I want to hear about it. Let me know in the comments below. I very much look forward to reading them. And I’ll feature the best ones in a future episode or episodes of Development That Pays.
