What is Work-Study?

Work-study examines organizational operations to optimize the use of industrial resources such as manpower, materials, machinery, and finances. Companies aim to produce high-quality products in the shortest time possible.

The production time for an item is influenced by the manufacturing process. Method study, a component of work-study, seeks to identify the most efficient manufacturing procedures that minimize time and prevent worker fatigue. This is achieved by eliminating unnecessary motions in a process or implementing the most suitable sequence of operations.

Definition of Work-Study

"Work Study is a broad term for techniques like Method Study and Work Measurement. These methods are used to analyze human work in various settings, systematically investigating all factors influencing efficiency to drive improvement.”

What is Method Study?

Method study is a systematic method of analyzing the manufacturing procedure of doing a job including human movements involved in it. In other words, it is the process of analyzing the methods and finding the best possible method which involves minimum time, not make fatigue to the workers and increase productivity. That’s why it is also termed as work simplification.

Method study is generally done by eliminating all unnecessary motions involve in a certain manufacturing procedure or by changing the sequence of operation or change the whole process.

Method Study procedure

1. Select the work which deserves to work-study and define the objective we need to achieve. Generally objective is to reduce the manufacturing cost, reduce bottlenecks or reduce fatigue of the worker with the aim of increase the efficiency.
2. Record all the relevant data which are essential for the method in chart form to obtain a more clear picture of the respective methods. Process of recording can be easily done with the help of the following aids-
   • Process and multiple activity charts (Outline process chart, Flow Process chart, Two-handed process chart)
   • Making Diagrams, (Flow diagram, string diagram, calligraphy and Cronocyclegraph diagram)
   • Motion and Memomotion studies, (Simo Chart)
   • Making Models.
3. Examine all the recorded data in sequence. During the Critical examination process number of question can be asked, like –
   • Purpose of the event,
   • Who does it? ,
   • The place where it is done? ,
   • How?
   • When the event is done?
   • How differently we can be done? etc.
4. Develop the best method of doing the event from the Critical Examination and record the method. But we have to keep in mind that Developed method should be practical, safe, economical and effective at the same time.
5. Install the finally developed method or improve the method. The installation process involves three phases, Planning, Arranging and Implementing. During the planning and arranging phase programme of installation, making time table, the necessary arrangement of resources, equipment, tools are made. In the implementation or actual installation phase, the developed method is introduced as the standard practice.
6. Maintain the new method, and ensure the proper functioning of the installed method by periodic inspection and verification. the aim of check and verification is to ensure if the method is being practised the same or it has deviated from the authorized one. Take the views of workers, supervisors it helps to explore further improvements.

What is Work Measurement in Work-Study?

Work measurement is one of the two foundational components of work study in industrial engineering. It focuses on establishing the standard time it should take a qualified worker to complete a specific task using the most efficient method identified through method study (the other half of work study).

Here’s a breakdown of work measurement in work-study:

• Focus: Determining the time a qualified worker needs to complete a task at a defined level of performance.
• Techniques: Common techniques include:
  • Time Studies: An analyst directly observes and records the time taken for specific tasks by a worker.
  • Predetermined Motion Time Systems (PTS): Assigns standard time values to basic human motions, allowing for quicker estimation of task times.
• Benefits:
  • Provides a benchmark for evaluating worker performance and identifying areas for improvement.
  • Sets realistic production targets based on achievable timeframes.
  • Enables effective scheduling and planning of production activities.
  • Forms the basis for establishing fair and reliable incentive pay schemes for workers.

In essence, work measurement helps quantify the efficiency gains achieved through method study. It provides a data-driven approach to ensure tasks are completed within a reasonable timeframe while considering worker capabilities.
