Latest WGU Operations-Management C215 Practice Questions By Newman

Weeks of supply measures how long inventory will last based on average usage. It is calculated using the formula:

Weeks of Supply = (Average Inventory / Annual Cost of Goods Sold) 52

Substituting the given values:

Weeks of Supply = (1,200,000 / 8,400,000) 52

Weeks of Supply = 0.142857 52

Weeks of Supply 7.43 weeks

When rounded to the nearest whole number, the answer is 7 weeks.

In Operations and Supply Chain Management, weeks of supply is a key inventory performance metric because it:

Indicates inventory efficiency

Helps balance service levels and holding costs

Supports cash flow management

Enables comparison across products or firms

Too many weeks of supply signal excess inventory and high holding costs, while too few weeks increase the risk of stockouts and service failures.

Managers use this metric alongside inventory turnover to evaluate how effectively inventory supports demand while minimizing waste.

The 14 Points for Quality Improvement, developed by W. Edwards Deming, explicitly stress management's responsibility for quality and form a foundational element of Total Quality Management (TQM).

Deming argued that quality problems are systemic, meaning they originate primarily from management-controlled processes rather than individual workers. His 14 Points call on leadership to create an environment where quality can thrive through long-term thinking, process improvement, and employee involvement.

Key management-focused principles include:

Creating constancy of purpose

Adopting a new philosophy of quality

Eliminating dependence on inspection

Driving out fear in the workplace

Breaking down departmental barriers

Instituting leadership instead of supervision

Unlike statistical quality control charts, which are technical tools, Deming's points define managerial behavior and organizational culture. ''Fitness for use'' is a definition of quality, not a management system, and product design quality focuses only on one stage of the product lifecycle.

In Operations Management, Deming's framework reshaped how organizations view quality---shifting responsibility upward to leadership, not downward to operators. This philosophy underpins continuous improvement, employee empowerment, and long-term competitiveness.

By emphasizing leadership accountability, the 14 Points integrate quality into strategy, operations, supplier relationships, and workforce management, making them one of the most influential contributions to modern quality management.
