What is Agile Extreme Programming?

Extreme Programming is a software development technique that aims to increase software reliability and its flexibility to react to new customer or client requirements. During the mid-to-late-1990s, when working on the Chrysler Comprehensive Compensation System (C3), software developer Ken Beck pioneered the Agile Extreme Programming approach. He released Extreme Programming Explained in October 1999, explaining the whole technique to others, and soon afterward established the official website.

As with other Agile development methodologies, Agile Extreme Programming attempts to deliver iterative and frequent minor releases throughout the project, moreover enabling team members and customers to inspect and assess the project’s progress across the SDLC.

We’ll explore what Extreme Programming is and how it works throughout this article, from the values and concepts that underpin it to the rules and procedural best practices that guide implementing a new agile Extreme Programming project, so let’s get started!

Extreme Programming Value

XP is more than a collection of agile management procedures; it is a set of standards that will help your team operate more efficiently and successfully. The values of Agile Extreme Programming are:

Simplicity

Teams do the task which is at present. Each stage of a complex process is broken down into smaller, more manageable tasks for team members to perform accordingly.

Smooth communication

Teams collaborate on all aspects of the project, from requirement gathering to code implementation, and engage in daily standup meetings to keep all teams notified. Any complaints or issues are immediately handled.

Consistency in providing constructive feedback

In XP, teams adjust their processes to the task and client requirements, not vice versa. Therefore, the team should often present their program early to collect client feedback and make required adjustments.

Respect

Extreme programming fosters an attitude of “all for one and one for all.” Each team member, regardless of their position in the hierarchy, is valued for their efforts. The staff values the customers’ perspectives and vice versa.

Courage

Team members respond to different circumstances and take ownership of their job. They are honest about their achievements; there are no “half-truths” or justifications for their inability to help people feel better. There is no need to be worried since nobody works individually.

Extreme programming methodology’s rules

Don Wells released the first XP guidelines in 1999 to refute allegations that extreme programming does not support essential software development tasks such as planning, management, and design. Follow these fundamental processes for each iteration, from planning to testing the program.

Planning

Rather than comprehensive requirement specification, the client creates user stories that detail the functionality they want to see and the value creation and importance assigned to each feature. User stories do not have to be comprehensive or technical; they need to offer enough information to assist the team in estimating the time required to develop those features.

The team then develops a release plan and breaks the project down into iteration (one to three weeks long). To communicate the schedule with the team, project managers may wish to construct a timeline or a simplified Gantt chart.

Designing

This guideline relates to the importance of simplicity: Begin with the simplest design possible, since it will take less time to finish than the more complicated solution. Avoid early functionality additions. you should often refactor to maintain a clean and simple codebase. Create spike solutions to investigate possible issues before they become a burden to your team.

Additionally, Kent Beck and Ward Cunningham developed class-responsibility-collaboration (CRC) cards to be used in conjunction with the XP approach. These cards enable the whole project team to collaborate on system design and seeing how things interact.

Coding

Finally, the moment has come to implement code. XP adheres to the principle of collective code ownership: Every developer has the ability to examine code and add features, correct problems, or restructure accordingly. To ensure that collaborative code ownership is successful, the team should:

  • Select a system analogy
  • Experiment with pair programming. Team members collaborate in pairs at a single computer to develop and deploy code. At any one moment, only one pair integrates code.
  • Every several hours, integrate and commit code to the repository.

The client should be present throughout this process, ideally on-site, to answer questions and establish the requirements.

Testing

Before the code can be published, the team runs unit tests and resolves problems. Additionally, they do regular acceptance testing.

When to utilize Extreme Programming

Even after reading its rules and principles, are you still uncertain if XP will meet your team’s needs. Extreme programming may be beneficial for teams that:

  • Expect the functionality of their system to change every few months.
  • Work with clients whose needs are always changing or who are unsure of what they want the system to accomplish.
  • Desire to minimize project risk, particularly in the face of tight timelines.
  • Employ a limited amount of programmers (between 2 and 12 is preferable).
  • Possess the ability to collaborate closely with clients.
  • Possess the ability to develop automated unit and functional tests.

Conclusion

If your team places a priority on communication and ongoing growth, extreme programming may be worth a try. Because this highly flexible approach demands continuous customer input, anticipates mistakes along the way, and forces workers to collaborate, XP not only guarantees a healthy product delivery but also inadvertently boosts efficiency for development teams worldwide.

What is Agile Kanban Methodology?

Kanban is an agile approach that focuses on continuous improvement, management flexibility, and improved workflow. Project managers can easily evaluate the progress of the whole project at a glance by using the kanban methodology.

Moreover, the Kanban methodology is one of the easiest frameworks since it enables project managers to organize and monitor their projects effectively. Among the characteristics that set the Kanban framework apart from other agile methods is its compliance with any existing management structure.

In contrast to other popular frameworks, Kanban encourages simplicity but also making significant modifications to the current setup. Conventional companies prefer to use it as they value hierarchy and the responsibilities of functional managers.

History of Kanban Methodology

Kanban is an Agile framework. Taiichi Ohno, a Japanese engineer, invented it in the late 1940s. The Agile Kanban Model concentrates on visualizing the whole project on boards to improve project visibility and team communication.

In the past, industries utilized kanban in their organizational settings to manage inventories across the supply chain. For instance, businesses used it to maintain just-in-time (JIT) production and lean production.

In software development, the Kanban technique modifies this idea by guaranteeing that the quantity of work needed is proportional to the team’s work capabilities. Moreover, in software development, we have JIT compilation or just-in-time compilation. It is a method used by runtime interpreters for languages such as JavaScript, C#, and Java to bring execution rates near to those of precompiled binary languages such as C++.

How to implement kanban methodology?

The Kanban technique is based on the kanban board. It is a tool that visualizes the whole project to assist users in tracking the progress of their work. Through this pictorial representation of Kanban boards, a new member or an external entity may comprehend what is occurring now, what tasks we have finished, and what tasks will be in the future.

What Is A Kanban Board? - The Fundamentals
Kanban Board

The kanban board includes:

  1. Backlog
  2. To Do
  3. Ongoing
  4. Done

The columns are interconnected, and tasks are taken from the backlog to the right column. Kanban utilizes the Work in Progress concept to track the work lifecycle.

In addition, limiting work in progress to sustain best practices is one of the guiding principles of the Agile Kanban methodology. The team must accomplish the present tasks in the sequence specified.

Principles of Kanban

The Kanban method’s fundamental concepts are as follows:

Begin with the current workflow

Begin with the current workflow: The Kanban framework puts a focus on continuous improvements. As a result, the team must begin with the existing workflow and continually enhance it.

Limit current tasks 

The team must recognize its limitations and limit progress accordingly. Adding more than you can manage simply loses time and affects the project badly.

Maintain current roles and responsibilities 

A key reason for Kanban’s success is that it does not force companies to restructure their work cultures. Many companies reject contemporary methods because of a fear of change.

Kanban increases efficiency while remaining within the constraints of the current setup.

Promote leadership at all levels 

Traditional project management methods, such as the waterfall method, demand approval of even the simplest activities by the project manager. Kanban empowers the person working on the task with decision-making authority. This fosters leadership skills which are constantly improving their work and learning from their errors.

Difference b/w Scrum and Kanban

Scrum and Kanban are regarded as the pillars of an Agile approach. According to PMI, more than 57% of companies employ various Agile methods, with Scrum and Kanban accounting for the most significant share.

While both Kanban and Scrum emphasize delivering the product regularly and iterating until we reach perfection, their approaches are very different. Both Kanban and Scrum methodology adhere to the Agile approach ideals and principles, however, the method is very different.

In Scrum methodology, we divide the work into chunks called sprints. In comparison, Kanban concentrates on continual development and ensures that tasks are completed on time.

Similarly, since Kanban is task-based, modifications may be made at any moment, while Scrum methodology requires the fulfillment of a single sprint plan before any adjustments can be implemented. As a result, Kanban is a good fit for projects that need a high degree of adaptability, while Scrum methodology is a better fit for processes involving work in batches.

Additionally, Kanban has no defined responsibilities, and no person is accountable for the team or a task. On the other hand, Scrum methodology pre-defines the duties of the Scrum Master, the Product Owner, and the Team members.

Tools used for Kanban

Several project management solutions include kanban boards. One of these tools is SpiraTeam®. It offers dashboards for key project quality and performance metrics — criteria test coverage, task progress, project pace, as well as top risks and problems – in a consolidated view that is optimised for Kanban projects while still supporting legacy/hybrid waterfall projects.

Kanban Methodology in Conclusion

A Kanban system is more than a wall of sticky notes. The most straightforward approach to grasp Kanban is to adopt its concept and incorporate it into your everyday work. If you study, comprehend, and identify with its fundamental ideas, the practical shift will seem reasonable, if not inevitable.

By visualizing workflow, establishing work-in-progress boundaries, controlling flow, enforcing clear guidelines, and collaborating on process improvement, you can take your process to new heights. Maintain frequent feedback loops, and all of these components together will show Kanban’s true potential. There is no one-size-fits-all approach for managing software development projects. Agile kanban is not for everyone since some teams may find that alternative methods are more successful. As a project manager seeking to simplify your procedures, it is up to you to decide what works best for your team.
