==**__Human Scale Ergonomics and Frank Gilbreth's 'Therbligs'__ ** ==


 * Question 1: **Write three paragraphs to define the term 'ergonomics'.

//According to the dictionary,// //ergonomics is the applied science of equipment design, as for the workplace, intended to maximize productivity by reducing operator fatigue and discomfort.//  //Ergonomics research helps the designer to create equipment that better suit people’s lifestyle and human form so that it puts less stress on the body. Ergonomics also controls external factors such as light, noise, temperature, etc, to allow workers to productively work longer hours.  //  //There are six ergonomic issues: comfort and simplicity, incorrect height and depth, task lighting, freedom of movement, prolonged laptop use, and usable desk space. Ergonomics focuses on the worker and looks at the worker’s needs, such as the video demonstrates.
 * Answer:**

 // //Ergonomics can be broken down into three categories: physical ergonomics, cognitive ergonomics, and organizational ergonomics. Physical ergonomics deals with the way the body interacts with the workers’ equipments and as well their effects on the body. Cognitive ergonomics relates to the mind. It is the way the mind processes information. Organization ergonomics deals with optimizing the workplace.//


 * Question 2: **What is the 'Gilbreth system of motion analysis'

//The Gilbreth system of motion analysis studies the movement of workers while they perform a task. Motion studies were first applied to brick laying. The traditional method consisted of stooping, walking and reaching. To eliminate waste motion, he designed a non-stooping, scaffolding platform. This device was patented in 1891. Workers had more energy and were less fatigued, improving productivity and performance.//
 * Answer:**


 * Question 3: ** Who was Frank Therblig, and how did he utilize 'motion study'?

//Frank Gilberth was an early advocate of scientific management.// //He began as a bricklayer, became a building contractor, an inventor, and evolved into management engineer.//    //‘Therblig’ is an anagram of Gilbreth, coined by//  //Frank and Lillian Gilbreth for their system of studying, timing and analysing the motions of workers//  //. //  //Frank looked at the movement of people and how they use their body when they were working. He examined the work process, timing the amount it took to complete the task. After recording the result, he would change the method to allow workers to be more productive.//
 * Answer:**

//Three categories Frank Gilbreth used in this Therblig Analysis Checklist are: Rest to Overcome Fatigue, Reach and Move, and Release.
 * Question 4: **Describe three categories Frank Gerblith used in the Therblig Analysis Checklist.

Rest to Overcome Fatigue: deals with allowing workers to take breaks so they are not overly exhausted and ensures work conditions are comfortable.// //Reach and Move: describes use of body parts.// //Search: describes the ability to locate and recognize the things around the worker//.
