Agile has had a huge impact on me both professionally and personally as I've learned the best experiences are agile, both in code and in life. You'll often find me at the intersection of technology, photography, and motorcycling. Collaborative design iterates on a product design by seeking the perspectives of your customers and developers at the outset of a project.

Transparency — sharing information openly using clear and straightforward language improves the flow of business value. Balance — different aspects, viewpoints, and capabilities must be balanced in order to achieve effectiveness. Collaboration — Kanban was created to improve the way people work together. Customer Focus — Kanban systems aim to optimize the flow of value to customers that are external from the system but may be internal or external to the organization in which the system exists.
Leadership — Leadership the ability to inspire others to act via example, words, and reflection is needed at all levels in order to realize continuous improvement and deliver value. Understanding — Individual and organizational self-knowledge of the starting point is necessary to move forward and improve. Agreement — Everyone involved with a system are committed to improvement and agree to jointly move toward goals while respecting and accommodating differences of opinion and approach.
These principles acknowledge that organizations are a collection of interdependent services, and to place the focus on the work, not the people doing the work. Kanban systems use mechanisms such as a kanban board to visualize work and the process it goes through.
In order for the visualization to be the most effective, it should show. When you establish limits to the amount of work you have in progress in a system and use those limits to guide when to start new items, you can smooth out the flow of work and reduce lead times, improve quality, and deliver more frequently.
The flow of work in a service should maximize value delivery, minimize lead times and be as predictable as possible. Teams use empirical control through transparency, inspection and adaption in order to balance these potentially conflicting goals. A key aspect of managing flow is identifying and addressing bottlenecks and blockers. Explicit policies help explain a process beyond just the listing of different stages in the workflow. Policies should be sparse, simple, well-defined, visible, always applied, and readily changeable by the people working on the service.
Examples of policies include: WIP Limits, capacity allocation, definition of done, and other rules for work items existing various stages in the process. Feedback loops are an essential element in any system looking to provide evolutionary change. The Feedback loops used in Kanban are described in the Lifecycle section.
Kanban starts with the process as it currently exists and applies continuous and incremental improvement instead of trying to reach a predefined finished goal. Use the roles you currently have on your team. There are two roles that have emerged in practice that serve particular purposes. Understands the needs and expectations of customers, and facilitates the selection and ordering of work items at the Replenishment Meeting. This function is often filled by a product manager, product owner , or service manager.
Responsible for the flow of work to deliver select items to customers. Facilitates the Kanban Meeting and Delivery Planning. Other names for this function include flow manager, delivery manager, or flow master. Because work items tend to flow through a kanban system in single piece flow, and each system is different with respect to stages in its workflow, the best way to describe the lifecycle of the Kanban method is via the feedback loops involved.
Understand the balance between and across services, including deploying people and resources to maximize value delivery. Examine and improve the effectiveness of a service. This is similar to a retrospective that is focused on improving the kanban system. Identify items that the team will work on and determine which work items may be selected next. This is analogous to a planning meeting for a sprint or iteration.
A team working on a service coordinates their activities for the day. This is analogous to a daily standup. The Kanban Method formalized the flow approach to knowledge work and offered a means for organizations to improve their software development processes and adopt agile values and principles without first having to undergo substantial cultural change.

Kanban aims at developing a service-oriented approach. Delivering value to the customer should be at the center of each organization. Understanding the needs and expectations of your customers brings the attention to the quality of the provided services and the value it creates. Once developed, a service-oriented approach requires continuous evaluation to foster a customer service culture. Through the use of regular reviews of the network of services and assessment of the applied work policies, Kanban encourages the improvement of the delivered results.
When aiming to implement the Kanban method, every organization must be careful with the practical steps. Six core practices need to be present for a successful implementation. A simple Kanban Board.
To visualize your process with a Kanban system, you will need a board with cards and columns. Each column on the board represents a step in your workflow. Each Kanban card represents a work item. The Kanban board itself represents the actual state of your workflow with all its risks and specifications.
The first and most important thing for you is understanding what it takes to get an item from a request to a deliverable product. Recognizing how work flows through your system will set you on the path to continuous improvement by making well-observed and necessary changes.
This way, you can easily track progress and spot bottlenecks. Naturally, your Kanban board might have a different outlook as it depends on your specific needs and processes. One of Kanban's primary functions is to ensure a manageable number of active items are in progress at any one time. If there are no work-in-progress limits , you are not doing Kanban. Limiting WIP means implementing a pull system on parts or the complete workflow. Such constraints will quickly illuminate problem areas in your flow so you can identify and resolve them.
Managing the flow is about managing the work but not the people. By flow, we mean the movement of work items through the production process at a predictable and sustainable pace.
One of the main goals when implementing a Kanban system is to create a smooth, healthy flow. Instead of micro-managing people and trying to keep them busy all the time, you should focus on managing the work processes and understanding how to get that work faster through the system. This would mean that your Kanban system is creating value more quickly. This is why your process should be clearly defined, published, and socialized. People would not associate and participate in something they do not believe would be useful.
When everyone is familiar with the common goal, they would be able to work and make decisions regarding a positive impact. For teams and companies that want to be more agile, implementing feedback loops is a mandatory step. They ensure that organizations are adequately responding to potential changes and enable knowledge transfer between stakeholders.
Kanban suggests the use of cadences feedback loops at a team level as well as service-oriented cadences. An example of a team-level cadence is the daily Team Kanban Meeting for tracking the status and the flow of work.
Creating a Kanban board is the first step towards visualizing your software development process. By creating a visual model of your work and workflow, you can observe the flow of work moving through your Kanban system. Visualizing work in Kanban means not only visualizing the process, but visualizing each piece of work represented by a Kanban card as it moves through that process.
Teams find that making the work visible, along with blockers, bottlenecks and queues, instantly leads to increased communication and collaboration. Visualizing all work across the team also helps establish accountability and transparency across the team. This is invaluable, especially for software development teams, which require coordinated efforts to get their work done efficiently.
Software development teams can easily get overwhelmed with their long list of to-dos; between new features, bug fixes, maintenance work, and other project work, teams often struggle to prioritize work in a disciplined, methodical way.
An important concept in the Kanban software development process, then, is limiting work in process, or WIP. By limiting how much-unfinished work is in process, you can reduce the time it takes an item to travel through the Kanban system. You can also avoid problems caused by task switching and reduce the need to constantly re-prioritize items.
Limiting WIP at both the personal and team levels can help software development teams move faster, reduce error, and collaborate more effectively. A deliberate emphasis on optimizing for flow is a critical element of any Kanban software development process. Flow describes the way work moves through your Kanban system. Good flow means that work moves in a fairly linear path, from one step to another with little delay between them.
