What is Statistical Process Control? Statistical Process Control (SPC) uses statistical methods to monitor a manufacturing process and understand how it changes over time. It helps teams distinguish normal process variation from unusual changes that may require investigation. In simple terms Suppose a machine produces metal shafts with a target diameter of 10 mm. Even […]

What is a Spaghetti Diagram? A Spaghetti Diagram is a visual tool used in Industrial Engineering to map the actual movement of people, materials, or equipment through a workplace. The movement paths often look like tangled spaghetti, revealing unnecessary travel and inefficient layouts. In simple terms Instead of guessing why an operator spends too much

What is Performance Rating? Performance Rating is the assessment of an operator’s working pace compared with a defined normal performance level during a time study. It helps an Industrial Engineer adjust observed time when the operator is working faster or slower than the normal pace. In simple terms If an operator completes a task unusually

What is Standard Time? Standard Time is the time allowed to complete a specific task under defined working conditions, including appropriate allowances for fatigue, personal needs, and unavoidable delays. It helps establish a realistic expectation for how long a properly trained operator should take to complete the work. In simple terms If an operator’s observed

What is a Value-Added Activity? A value-added activity is an activity that changes the product in a way the customer requires and is willing to pay for. Examples: What is a Non-Value-Added Activity? A non-value-added activity consumes time, effort, space, or resources without increasing the value of the product. Examples: Simple Example Consider an assembly
