Study Notes

Eight Areas of Waste

Waste is the loss of something valuable due to excessive usage, ineffective or unnecessary usage.
The Toyota Production System coined the term "Muda" to describe waste.

Types of Waste

Defects: Imperfections that decrease value or utility.
- Caused by machine wear, human error, unclear specifications, tampering, or neglected machinery.
- Impacts qualitative attributes like appearance, size, delivery timeliness, and price symmetry.
- Auditors should determine expectations and compare results against standards.
Overproduction: Producing more output than needed.
- Often driven by economies of scale, where fixed costs are shared over more goods.
- To address risks, organizations perform counts, use climate-controlled facilities, implement access controls, and build infrastructure.
- In service environments, consider: excessive printing/faxing, repetitive data entry, and unnecessary tests or services.
Waiting: Delays in action while waiting for another action to be completed.
- Often a result of non-value-added activities and lack of coordination.
- Examples include: waiting for primer to dry, concrete curing, or missing information.
- Auditors should identify waiting occurrences, reasons, and involved parties to recommend process improvements.
Non-utilized Talent (Underutilized Employees): Resources are underutilized, resulting in decreased productivity.
- Organizations waste talent by not providing opportunities for employees to fully use their skills.
- Internal auditors should audit employee engagement as it impacts productivity, retention, customer satisfaction, and internal control.
Transporting: Unnecessary movement of items from one location to another.
- Involves excessive handling of materials, shuffling of inventory, and time wasted on transportation.
- Impacts workplace settings through poor layout, batch sizes, and shared machines.
- Telematics can track idle time and route efficiency to optimize transportation.
- Ways to reduce transportation waste include reducing batch sizes and designing product-oriented work cells.
Inventory: Excess goods, parts, and materials on hand.
- Includes products, materials, parts, and documentation not being processed immediately.
- Inventory incurs carrying costs, ties up capital, and can be written off as excess or obsolete.
Motion: Operations in a poorly designed work environment.
- Results from poor workspace layout, insufficient ergonomics, and excess movement while searching for items.
- Impacts individual motion with financial and time waste, physical ailments like RMDs, and increased workers’ compensation premiums.
- Value stream mapping is a tool to visualize flows through systems and track routes through workplaces.
Extra Processing (Unnecessary Paperwork or Processing): Unnecessary paperwork or processing steps.
- Transitioning to paperless processes reduces costs, improves productivity, saves space, and simplifies documentation and information sharing.
- Technologies like e-forms, workflow applications, Web servers, and PDF adoption can be used.

Identifying, Assessing, and Preventing Waste

Internal auditors play a crucial role in identifying, assessing, and preventing waste.
Auditors perform audits at the beginning of cycles to detect anomalies and help management prevent them.
By addressing waste, organizations can improve efficiency and achieve financial and operational objectives.
Consider the financial, time utilization, ecological, health, and safety implications of waste.
