The Expedite swim lanes concept has become increasingly prominent within Kanban and workflow management. While intended to streamline processes, these lanes often lead to the opposite effect, disrupting what makes Kanban a powerful tool for workflow optimization.
This article, inspired by the principles of ProKanban.org and the insights of Daniel Vacanti, unpacks why Expedite swim lanes are counterproductive in creating predictable Kanban workflows and what alternatives might better serve the continuous improvement process.
Understanding Expedite Swim Lanes
Before we delve into the impact of Expedite swim lanes on Kanban workflows, it’s essential to understand what these lanes are and their intended purpose.
In a Kanban system, the board is a visual representation of work, often segmented into various sections to organize and prioritize tasks. These sections, known as swim lanes, run horizontally across the board, each representing a different category or type of work.
Definition and Purpose of Expedite Swim Lanes
An Expedite swim lane is a specific type dedicated to urgent tasks. These are tasks that, for various reasons, have been designated as high-priority and require immediate attention.
The rationale behind this concept is straightforward: teams can quickly identify and address these critical items by isolating urgent tasks in a separate lane, ensuring they are completed as soon as possible.
This approach seems logical, especially when unexpected critical tasks frequently arise. The Expedite swim lane is designed to provide a clear visual signal that a task needs to be fast-tracked, bypassing the usual workflow stages.
The Intention Behind Expedite Swim Lanes
The Expedite swim lane is rooted in a well-intentioned desire to adapt to changing priorities and unforeseen urgent demands.
In theory, this special lane acts as a pressure valve, allowing teams to handle critical issues without disrupting the standard flow of work. It’s seen as a tool for maintaining flexibility and responsiveness in a dynamic work environment.
Overlooked Implications on Workflow
However, despite these intentions, introducing Expedite swim lanes often leads to unintended consequences.
While they aim to solve urgent tasks, their existence can inadvertently create a dichotomy in the workflow process. The presence of an Expedite lane can send a message that tasks within this lane are the only ones requiring immediate attention, inadvertently downgrading the importance of work in other lanes.
Moreover, the very nature of an Expedite lane assumes that the team can accurately and consistently determine what qualifies as urgent. This determination is often subjective and can lead to frequent shifts in focus as different tasks vie for the ‘urgent’ label. The squeaky wheel principle conditions all stakeholders to lobby for the expedite lane at the whole system’s expense.
The result is a potential disruption in the regular workflow, as resources are diverted to the Expedite lane, leading to bottlenecks and delays in other areas of the board.
While Expedite swim lanes are designed to enhance efficiency and responsiveness, they can, in practice, create a counterproductive environment. The challenge lies in managing these lanes in a way that truly benefits the workflow without undermining the principles of Kanban, such as flow, visibility, and predictability.
The Paradox of Urgency: Disrupting Flow and Clarity
One core principle of Kanban is maintaining a steady and predictable workflow. Expedite swim lanes, however, introduce a disruptive element into this flow.
By prioritizing urgency over process, these lanes can lead to confusion and duplication of effort. Teams may find themselves constantly shifting focus to expedited tasks, leading to a breakdown in the regular workflow and causing delays in other areas.
This constant shifting hinders the team’s ability to predict workflow timelines and affects the quality of work.
Real-World Implications
Example #1: Software Development Team
Consider a software development team using a Kanban board. The Expedite swim lane is introduced to manage a critical bug fix that needs immediate attention. Initially, this approach seems justified as it addresses the urgent issue quickly.
However, this can result in other significant tasks being pushed aside, leading to a cascade of delays. Regular tasks get consistently deprioritized, and over time, this reactive approach becomes the norm. The team’s work environment turns chaotic, with the urgency of tasks consistently overshadowing their strategic importance or long-term value.
Example #2: Marketing Agency
Now, let’s look at a marketing agency scenario. The agency uses a Kanban board to manage its various client projects, including campaigns, content creation, and design work.
An Expedite swim lane is created for urgent client requests, such as last-minute changes to a campaign or rush design jobs. Initially, this seems like a proactive way to handle client demands swiftly.
However, the frequent use of the Expedite lane begins to disrupt the regular workflow. Projects that were planned and scheduled in advance get delayed as team members shift their focus to expedited tasks.
This leads to a backlog of work in the standard lanes, increasing stress among team members and potentially impacting output quality. Clients expecting routine tasks to be completed on time face unexpected delays, harming the agency’s reputation for reliability.
Alternative Strategies for Managing Urgent Tasks
Rather than relying on Expedite swim lanes, Kanban practitioners can use several alternative strategies to handle urgent tasks effectively without disrupting the overall workflow. These strategies are designed to integrate urgency into the workflow while maintaining the principles of Kanban, such as flow and predictability.
Create a Strict Definition/Policy Around Urgency
Establish clear criteria for what constitutes an ‘urgent’ work. This involves setting specific parameters or conditions that a task must meet to be considered urgent. By having strict definitions, teams can objectively assess the urgency of tasks, preventing the arbitrary or overuse of the urgent label.
Explanation. This approach ensures that only tasks that genuinely require immediate attention are treated as such, thereby maintaining the overall workflow’s structure and preventing unnecessary disruptions.
Set WIP (Work in Progress) Limits for Urgent Work
If you are certain that an expedite lane is necessary in your contest, implement WIP limits specifically for urgent tasks. This means setting a cap on the number of urgent tasks that can be in progress at any given time.
Explanation. WIP limits prevent the team from being overwhelmed by urgent tasks. It ensures that while urgent tasks are addressed, they only partially take over the team’s bandwidth, allowing regular tasks to progress simultaneously.
Schedule Reviews for Urgent Tasks
Conduct regular reviews to assess and prioritize urgent tasks. Focus on evaluating the urgency and importance of tasks in the queue.
Explanation. Regular reviews help reassess the urgency of tasks and make informed decisions about prioritizing them. This process ensures that urgency is addressed dynamically and keeps the team aligned on priorities such that the most urgent work is added to the board when capacity is available.
Emphasizing Predictability for Optimal Outcomes
The ultimate goal of any Kanban system is to achieve a predictable and efficient workflow. Expedite swim lanes, while well-intentioned, often undermine this objective. While possibly allowing for urgent work to be completed more quickly, Expedite lanes come at the expense of process predictability.
Teams and Kanban board designers must recognize the importance of maintaining a clear and focused workflow. Predictability enhances efficiency and improves planning, resource allocation, and team morale.
Learning from the Community
In the spirit of continuous improvement, it’s beneficial for Kanban practitioners to share their experiences and insights. Engaging in discussions about managing urgent tasks within Kanban systems, both online and in professional settings, can provide valuable perspectives and innovative solutions.
Platforms like ProKanban.org offer a wealth of resources and a community for those looking to deepen their understanding of Kanban workflow management.
Expedite Swim Lanes Are Not the Answer
While Expedite swim lanes might seem like a quick fix for managing urgent tasks, their long-term impact on workflow predictability and efficiency is often detrimental. By exploring alternative strategies and emphasizing the importance of a steady workflow, Kanban practitioners can avoid the pitfalls of these lanes. Continuous improvement and adaptability remain key in optimizing Kanban processes, ensuring that the system remains a powerful tool for workflow management.
