Motion Study is the systematic analysis of human motions used in performing a task. The goal is to eliminate unnecessary motions, simplify work, and increase efficiency.
Itβs closely related to Time Study, but while Time Study focuses on how long a task takes, Motion Study focuses on how the task is done.
π Why is Motion Study Important?
-
Reduces Fatigue: By eliminating awkward or excessive motions.
-
Improves Productivity: Helps design more efficient work methods.
-
Enhances Safety: Identifies risky or harmful movements.
-
Lowers Costs: More efficient motions lead to lower labor costs.
π§° How is Motion Study Done?
-
Select the Task: Choose a repetitive or critical task.
-
Observe the Movements: Watch how the task is performed (can use video recordings).
-
Break Into Basic Motions: Identify small body movements (e.g., reach, grasp, move, release).
-
Analyze Each Motion: Check if the motion is necessary, if it can be simplified, or eliminated.
-
Design Better Methods: Create a more efficient way of performing the task using fewer or better motions.
-
Implement & Train: Apply the new method and train employees.
π§ Example:
Imagine a worker in a packaging line:
-
Old method: Picks up a box, walks 2 steps, gets tape, then returns to seal it.
-
Motion Study reveals: The tape can be placed next to the box.
-
Result: Saves time, energy, and boosts speed.
π― Key Concept: Therbligs
Developed by Frank and Lillian Gilbreth, therbligs are 18 elemental motions (like reach, grasp, hold, position, release) used to analyze tasks scientifically.
β Applications in Business
