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

What is Ergonomics? Ergonomics is the science of designing workstations, tools, equipment, and tasks to fit the worker. The goal is to make work safer, more comfortable, and more efficient. In simple terms Instead of asking: “How can the operator adapt to the workstation?” Ergonomics asks: “How can we design the workstation so the operator

What is Waste in Manufacturing? In Lean Manufacturing, waste means any activity that consumes resources but does not add value from the customer’s perspective. A process can look busy and still contain significant waste The 8 Wastes Simple Example An operator produces a component in 30 seconds, but spends another 10 seconds walking to collect

What is a Manufacturing KPI? A Manufacturing KPI (Key Performance Indicator) is a measurable value used to understand how effectively a manufacturing process is performing. KPIs turn production performance into data that can be monitored and improved. In simple terms Instead of saying: “Production seems slow.” A KPI helps quantify it: Output = 8,500 units

What is Performance Rate? Performance Rate measures how fast a machine or production process operates compared with its ideal or planned production speed while it is running. It helps answer: “When the machine is running, is it producing as fast as it should?” In simple terms A machine may be available for production but still

What is Quality Rate? Quality Rate measures the proportion of produced units that meet the required quality standards compared with the total units produced. It helps answer: “How much of what we produced was good without being rejected?” In simple terms If a process produces 1,000 units and 30 units are defective: Good units =
