• Improve procedures
• Improve layout
• Reduce human fatigue
• Improve use of materials, machines, labor
• Improve physical workplace

1 Select Project

• Human factors
• Technical factors
• Economic factors
• Exploratory tools
• Pareto analysis
• Gantt chart

PARETO ANALYSIS (80-20 Rule)

• Vilfredo Pareto economist
• 80 of money held by 20 of people
• 80 of costs, accidents, injuries, accounted for
  by 20 of jobs/individuals
• Concentrate on those 20
• Plot in descending order as a cumulative
  probability distribution (DesignTools)

8
GANTT CHART

• Horizontal bar chart of activities
• Shade in bar as completed
• Any given point in time, a snapshot of the status
  of all activities
• Some behind, some ahead of schedule
• Again focus efforts where needed

METHODS STUDY (NEXT?)

• Get and present data
• Analyze data
• Develop ideal method
• All of these overlap
• Use special charts or procedures
• Quicker, more efficient
• Designed specifically for IEs

14

• Charts using sequence only
• Operation (outline) process chart
• Flow process chart
• Two-hand process chart
• Charts using time
• Multiple activity chart
• Simo chart
• Charts indicating movement
• Flow diagram
• Travel chart
• Motion analysis

15
PROCESS CHARTS

• Record sequence of flow for worker,
• material, or tools/machines
• Outline (operation) vs flow
• Supply basic information date, job, worker
• ASME symbols for activities (shorthand)
• Vertical lines main flow
• Horizontal lines subcomponents to main
• Summary compare before and after
