INEN 3380 Test 2 Questions And Quality Answers

There are certain fundamental requirements before a time study is conducted. One such fundamental requirement is ____________. - Correct Answer the operator is thoroughly acquainted with the technique being studied An unusual or suspect element time is circled to indicate a wild value. - Correct Answer True The elements of work commonly included in setup standards involve all events that take place between completion of the previous job and the end of the present job. - Correct Answer False If a time study is performed in accurately and the resulting time standards are too tight , the company s profitability may decrease due to the morale of the operators. - Correct Answer True The number of cycles in a time study is determined by_____. (Choose all that apply) - Correct Answer 1) the type of activity of the job 2) the cycle time of the job 3) the variation in cycle times 4) the desired confidence in or accuracy of study Why is it necessary to rate the operator? (Select all that apply) Ch. 10 - Correct Answer 1) the operator should be rated in order to adjust the time of a good operator up to the standard 2) the operator should be rated in order to adjust the time of a poor operator down to the standard An analyst should sit if possible while conducting a time study. - Correct Answer False When considering an operator for a time study, the operator should be_____. (Choose all that apply) Ch. 10 - Correct Answer 1) experienced 2) cooperative 3) a person who has a record of performing at a pace or slightly above pace Constant elements should be separated from variable elements. - Correct Answer True An advantage of the snapback method is (select all that apply) Ch. 10 - Correct Answer 1) no clerical time is needed to make successive subtractions 2) elements performed out of order by the operator can be readily recorded without special notation 3) delays are not recorded 4) elemental values can be compared from one cycle to the next (leads to decisions being made as to number of cycles to study) 5) elapsed elemental values read directly When an operator encounters an unavoidable delay this is called a ___________________. - Correct Answer foreign element If a time study is done correctly, the results will be a combination of loose and tight time standards. - Correct Answer False Standard Time is the time required for an average operator, fully qualified and trained, and working at a standard pace, to perform the operation. - Correct Answer True When performing a time study, rating the operator is very important. What benchmark does the author use when describing a standard pace? - Correct Answer worker walking without load, on smooth, level ground at a rate of 3 mi/h The continuous method of stopwatch recording is better adapted to measuring and recording very short elements when compared to the snap back method. - Correct Answer True When conducting a time study if the operator takes an unplanned water break, the observer should document this unplanned event in the_____ of the time study observation form. (Choose all that apply) - Correct Answer 1) foreign elements section 2) in the element section where the unplanned water break took place 3) allowance summary If the ambient temperature is higher than normal conditions during a time study, the time standard may need to be modified. - Correct Answer True With regards to a time study the author discusses two types of elements, they are __________________. - Correct Answer constant and variable elements In general manual and machine elements should be separated. - Correct Answer True Prior to the time study, if the working conditions deviate considerably from the normal working conditions, the time study should always be postponed. - Correct Answer False When using the continuous method of time recording, the W column of each element will have a time recorded. - Correct Answer False The time study analyst should ensure (Select all correct answers) - Correct Answer 1) correct method is being used 2) accurately record the times taken 3) honestly evaluate the performance of the operator 4) refrain from any operator criticism. Time studies are conducted to ensure employees are not taking longer on an element than required. - Correct Answer False Time will vary little in an________ element. - Correct Answer constant Time studies are used to establish time standards. - Correct Answer True Constant elements should be kept separate from dependent variable elements so they can be used as a source of standard data. - Correct Answer False For ease of measurements the operation or process should be divided into groups of motions called _________. - Correct Answer elements In time studies, the use of electronic watches has increased the use of ______. - Correct Answer the snapback method Foreign elements are elements that are planned for in the allowance summary prior to the time study. - Correct Answer False With regards to allowances, the author describes three classes of interruptions that can take place, they are____. (Choose all that apply) - Correct Answer 1) personal needs 2) foreign elements 3) basic fatigue BELOW ARE WHAT IS IN BOOK 1) personal interruptions 2) fatigue 3) unavoidable delays When selecting an operator for an activity of study, the operator should be - Correct Answer completely trained in the method, should like the work, and should demonstrate an interest in doing a good job Performance rating should be done prior to the observation of elemental times. - Correct Answer False Which operator interruptions would be covered by the unavoidable delays allowance? (Select all that apply) Ch. 11 - Correct Answer 1) Interruptions from the dispatcher 2) Interruptions from the supervisor 3) Interruptions from the study analyst 4) Interruptions from the material irregularities **also material irregularities, difficulty in maintaining tolerances and specifications, and interference delays where multiple machine assignments are made **choose ALL answers (check and make sure) What are the methods used in developing allowance standard data? (Select all answers that apply) - Correct Answer 1) production study 2) work sampling ** also says Direct Observation Speed rating is a performance evaluation method that considers the rate of work per - Correct Answer unit time Fatigue allowances are applied only to the automated (non manual) part of the work cycle, because during the machine part the operator can be overcoming fatigue by sitting down, i.e. resting. - Correct Answer False Illumination, noise, temperature, humidity, ventilation, weight of loads, posture, monotony of the task, repetitiveness of the task, mental strain of the task, etc. all affect fatigue. - Correct Answer True To be successful, analysts must develop track records for setting accurate standards that are accepted by - Correct Answer labor and management The Westinghouse method requires four factors in evaluating the performance of the operator: skill, effort, conditions and consistency. - Correct Answer True A major factor that affects fatigue is illumination, noise, temperature, humidity, ventilation, weight of loads, posture, monotony of the task, repetitiveness of the task, mental strain of the task, etc. all affect fatigue. - Correct Answer All of the above Many companies have modified the Westinghouse system to include only - Correct Answer skill and effort Many proponents of the MTM fundamental motion data system advocate that no allowance be provided for fatigue - Correct Answer True Fatigue allowances can be formulated on two important physiological principles, they are muscle fatigue and pharmacological recovery after fatigue - Correct Answer False Which percentage allowance seems adequate for personal delays under typical shop conditions? (As suggested in text book) - Correct Answer 5% Which percentage allowance is usually provided for avoidable delays? - Correct Answer 0%
