8 Wastes in the context of Kanban

8 Wastes in Kanban

In Kanban, the concept of 8 Wastes refers to the eight categories of waste identified in Lean manufacturing that can hinder the flow of value in a process. These wastes are crucial to identify and eliminate in order to optimize efficiency and improve overall productivity in software development projects following the Kanban methodology.

The 8 Wastes in Kanban are:

  1. Transportation waste: Unnecessary movement of items or information between different stages in a process.

  2. Inventory waste: Accumulation of excess work in progress, leading to delays and inefficiencies.

  3. Motion waste: Unnecessary physical or cognitive effort required to complete a task.

  4. Waiting waste: Delays caused by idle time or waiting for resources.

  5. Over-processing waste: Performing unnecessary tasks beyond what is required by the customer.

  6. Overproduction waste: Creating more output than necessary, leading to excess inventory or unused features.

  7. Defect waste: Errors or defects in the process that require rework, resulting in waste of time and resources.

  8. Skills waste: Underutilization of skills or knowledge within the team, leading to suboptimal performance.

By recognizing and addressing these 8 Wastes, teams practicing Kanban can streamline their workflows, reduce inefficiencies, and focus on delivering value to the customer more effectively.

8 Wastes in the context of Kaizen

8 Wastes in Kaizen

Kaizen is a Japanese philosophy that focuses on continuous improvement in all aspects of life, including business processes. In the context of Agile software development practices, Kaizen identifies "8 Wastes" that cause inefficiency and hinder progress. These wastes are derived from the Toyota Production System and are critical to understand and eliminate to improve overall productivity and quality.

The 8 Wastes in Kaizen are:

  1. Transportation: Unnecessary movement of products or materials.
  2. Inventory: Excess materials or work-in-progress that are not immediately needed.
  3. Motion: Unnecessary movement of people within the workspace.
  4. Waiting: Delays or idle time in the production process.
  5. Over-processing: Doing more work than necessary or adding unnecessary features.
  6. Over-production: Producing more than what is needed at the moment.
  7. Defects: Errors and rework that arise due to poor quality.
  8. Skills: Underutilization of the skills and knowledge of team members.

By identifying and addressing these wastes, teams can optimize their processes, reduce lead time, and deliver higher-quality products more efficiently.
