Behavioral Approaches to Job Design

• Job Enlargement– Giving a worker a larger portion of the total

task by horizontal loading

• Job Rotation– Workers periodically exchange jobs

• Job Enrichment– Increasing responsibility for planning and

coordination tasks, by vertical loading

Methods Analysis

• Changes in tools and equipment

• Changes in product designor new products

• Changes in materials or procedures

• Other factors (e.g. accidents, quality problems)

The need for methods analysis can come from a number of different sources:

Motion Study Techniques

• Motion study principles - guidelines for designing motion-efficient work procedures

• Analysis of therbligs - basic elemental motions into which a job can be broken down

• Micromotion study - use of motion pictures and slow motion to study motions that otherwise would be too rapid to analyze

• Charts
