Study Notes

Method Study Definition and Objectives

Method study is a systematic investigation of the existing method of doing a job to develop and install an easy, rapid, efficient, effective, and less fatiguing procedure.
Objectives of method study include:
- Improving efficiency and productivity
- Enhancing quality
- Reducing waste and costs
- Optimizing resource utilization
- Standardization and consistency
- Ensuring safety and ergonomics
- Facilitating training and skill development
- Promoting employee engagement and satisfaction
- Supporting continuous improvement
- Meeting customer needs and expectations

Procedure of Method Study

Select the work worth studying and define the objective to be achieved
Record all relevant information pertaining to the existing method
Examine the recorded events critically and in sequence
Develop the best method as resulted from critical examination
Install the best developed method
Installation involves three phases: planning, arranging, and implementing

Process Charts

Process charts are used to record different types of events
Five basic symbols are used to record different types of events:
- Operation
- Storage
- Delay or temporary storage
- Transport
- Inspection

Operational Analysis

Operational analysis is a detailed study of different operations involved in doing a work
It examines the shortcomings of the existing method and develops an improved procedure
The analysis considers the movements of the limbs and aims to find a simpler and economical method

Analysis of Motion

Analysis of motion is a detailed study of individual motions of a worker
The purpose is to design an improved method that eliminates unnecessary motions and employs human effort more productively
Steps involved in motion analysis:
- Select the operation to be studied
- List and chart various motions performed by the operator
- Identify productive and idle motions
- Eliminate unnecessary motions
- Redesign the existing operation procedure
- Impart necessary instructions to the worker

Principles of Motion Economy

Principles of motion economy are a set of rules designed to develop better methods
The principles are classified into four categories:
- Rules concerning human body
- Rules concerning workplace layout and material handling
- Rules concerning tools and equipment design
- Rules concerning time conservation

Time Study

Time study is the aspect of work study that determines the standard time for various operations
Objectives of time study include:
- Determining the standard time for various operations
- Estimating the cost of product accurately
- Predicting the duration of a particular work
- Determining the number of machines an operator can run
- Determining the optimum number of men and machines
- Providing information for planning and scheduling
- Balancing the work of all workers working in a group

Simultaneous Motion Cycle (SIMO)

SIMO is an extremely detailed left- and right-hand operation chart
It shows the simultaneous minute movements performed by the two hands of an operator on a common time scale
Construction of SIMO involves:
- Filming a number of short and repetitive work cycles using a 16 mm movie camera
- Selecting the most efficient performed cycle for analysis
- Analyzing the film frame by frame and recording the data
- Drawing a SIMO chart for further study and analysis
- Developing a better and improved procedure for doing a job
