Operation Analysis

Prcoess chart was the device developed by Gilbreths to record and study processes for productivity improvement.

The process chart was standardized by ASME to include 5 types of operations.

Production or material transformation operations
Inspection Operations
Transport Operations
Storage Operations
Delays in Process


Operation Analysis

Operation analysis may be defined as "A systematic procedure employed to study all of the factors which affect the method of performing an operation in order to achieve maximum over-all economy. Through this study the best available method of performing each necessary part of an operation is found, and new manufacturing and maintenance developments are incorporated as they become available, in the continuing effort to move every job one step closer to continuous automatic accomplishment." [Stegmerten and Demmler]

Operation-Analysis Approach

1. Observe or visualize operation.

2. Ask questions to yourself as well as to others

3. Investigate the Factors of the Operation -  10 Main Factors  to improvement of the operation

Part or Product Design Factors

    a. Design of part and/or assembly (for assembly operations)
    b. Material specification
    c. Tolerance specification
    d. Surface finish

Production Operations

    e. Purpose of operation
    f. Manufacturing technique employed
    g. Equipment analysis
   h. Tolerances and inspection requirements
    i. Tools and speed, feed, and depth of cut.
    j. Workplace layout
    k.  Motion analysis
     l.  Material flow

Inspection Operations

Purpose of operation
Inspection technique employed
Equipment analysis
Workplace layout
 Motion analysis


Transport Operations

Purpose of operation
Transport technique employed
Equipment analysis
Workplace layout
 Motion analysis


Storage Operations

Purpose of operation
Warehousng  technique employed
Equipment analysis
Workplace layout
Motion analysis


Delays

Inventory Analysis - Value Stream Mapping
Order quantity or batch quantity analysis
Ordering system analysis
Scheduling analysis




4. Compare old and new methods. Do Engineering Economic Analysis. [Stegmerten and Demmler]

The analysis can be written or mental.
The analysis can be for a class of work or for specific work.
Operators can be trained using audiovisual aids, in separate training sessions or by supervisors as on the job training.
