Scenario: Employees frequently have to walk long distances between departments to collect signatures for approvals, causing unnecessary physical strain and time wastage. What type of waste is illustrated here? a) Overproduction b) Motion c) Overprocessing d) Defects

Motion

Scenario: Employees spend excessive time searching through cluttered file cabinets for important documents, resulting in reduced productivity. What type of waste is evident in this scenario? a) Overproduction b) Inventory c) Motion d) Waiting

Defects

Scenario: In an office setting, outdated equipment leads to frequent breakdowns and repairs, causing delays in project completion. What type of waste does this scenario represent? a) Overproduction b) Defects c) Waiting d) Transportation

Overprocessing

Scenario: In an office, a significant amount of time is spent on redundant data entry tasks because of inconsistent software systems that do not communicate with each other. What type of waste is demonstrated in this scenario? a) Overprocessing b) Motion c) Defects d) Transportation

Defects

Scenario: In an office, documents are often lost or misplaced due to inefficient filing systems, resulting in rework and delays. What type of waste is highlighted in this scenario? a) Overproduction b) Inventory c) Defects d) Waiting
