The document discusses the 7+1 types of muda, or waste, that can occur in software development projects: 1. Defects such as bugs, incomplete tests, and missing documentation. 2. Non-value processes like unnecessary approvals, regulatory tasks, and timesheet management. 3. Eschewed talents where underutilized human potential exists. 4. Overproduction of features that are not needed by customers. 5. Waiting for tools, equipment, materials, information or people. 6. Transportation of physical goods or unnecessary movement of people. 7. Inventory that includes unused features, excessive backlogs, or delays in releasing software. 8. Motion involving unnecessary human movement

DOWNTIME or the 7+1 mudas in software development DEFECTS NON VALUE PROCESSES ESCHEWED TALENTS OVERPRODUCTION WAITING TRANSPORTATION INVENTORY MOTION When you are talking about Lean manufacturing is no difficult to visualize mudas; while talking about software development is not so easy, so in this poster you can see examples of mudas specific for software development, so it can be easier for you to face and fix it. Muda: japanese word for 束waste損. Things not demanded by actual customers Things awaiting further processing or consumption Things not working as expected Any unnecessary movement of people/goods inside the same location. Underutilized human potential, Any unnecessary movement of people/goods in other locations Waiting for tools, equipment, materials, information, people, Any activities that do not add value from the customer perspective. Task switching, unnecessary human motion, change of ownership. Unneeded buffering, Delay of release, developed sw not released, excessive backlog refined and never developed. Approvals on hold, pauses in flow, missing skills, access to the office. Rework, Bugs, incomplete tests, incomplete AC, missing documentation, incomplete DoD. Unused feature, wrong prioritization. Regulatory, timesheet, stakeholders management. Manual approvals, too many levels of approval, Missing automation in CI/CD. unsafe or unergonomic work conditions , any uncertainty about the right thing to do, unmotivated people, hard to use tool, task switching, not relevant metrics, block creativity
