[Audio] As explained in the Work Measurement module, the time for the best method is calculated using one of the following Work Measurement techniques : - Work Sampling Time Study MOST The outcome of a Work Measurement is the Normal Time..
[Audio] At Jabil we use 3 ways to calculate the Normal Time. Depending on the situation, we decide what technique is best to use: When the Work Measurement is for non-repetitive irregular activities, we could apply Work Sampling. When the Work Measurement is for repetitive work (mostly for Value Add Direct Labour), we better use Time Study or MOST. If the product is not in production yet or when the 'best method' is not defined yet, we can apply MOST. If the product is in production and the process follows the 'best method', we can apply Time Study. Each Work Measurement technique has it owns advantages and dis-advantages. At Jabil some typical areas where MOST can be applied are: Quoting High Volume Assembly Continuous Improvement.
[Audio] PMTS, or a Predetermined Motion Time System, is a work measurement technique whereby times established for basic human motions are used to build up the time for a job at a defined level of performance. It is A collection of basic motion times. Technique for obtaining a standard time by: analyzing and subdividing a task into elemental motions assigning pre-set standard times for motions and summing these to obtain a standard time for the whole task..
[Audio] Popular Predetermined Motion Time Systems are: Methods -Time Measurement (MTM) Work-Factor Predetermined Time Standards Systems – Meyers MOST When we look at the workcontent, we can split each job in different tasks. Each tasks consists out of different Work Elements (MOST Level) And each Work Element is a combination of different Basic Motions (MTM Level).
[Audio] MOST, or the Maynard Operation Sequencing Technique, is a predetermined motion time system that is used to set the standard time for a worker to perform a task; it is designed to simplify and speed up the process of setting engineered time standards, and is the primary work measurement tool used to establish standards here at Jabil. It is not only calculating the time, but also make the the engineer think to make sure this is done for the Best Method. To calculate these standard, MOST uses a catalog of standard times assigned to the fundamental motions that are often repeated that make up an activity, assigns time values – or time measurement units (TMUs) – associated with these motions to each step in the process, and then adds them together to derive a time standard for the task at hand. MOST times represent ranges of motion, and since these times are represented by a range of values, precise measurements are not required. However, incredibly accurate results are still produced with this technique, because the ranges in use are statistically derived..
[Audio] Without explaining all the details yet, here some examples of MOST calculations. While using MOST we should always follow a similar method: Identify the object Describe the method Construct the sequence model And finally calculate the corresponding TMU.
[Audio] How you benefit from MOST? • MOST is the fastest way to accurately measure work and to evaluate method improvements. MOST is simple to learn and easy to apply while retaining the accuracy of more detailed work measurement systems. • MOST eliminates the need for a stopwatch to time and subjectively performance rate the associate. MOST generates consistent results • MOST focuses the analyst's attention on analyzing the method instead of just the time. There is no need to time workers with a stopwatch because a MOST data card predetermines index values for each defined work method. Therefore also no Performance Rating is needed. By focusing on the working method, rather than on performance rating the worker, MOST can contribute to a more efficient workplace by identifying method improvement opportunities..
[Audio] There are several MOST methods with different levels of detail: Basic MOST Mini MOST Maxi MOST At Jabil Basic MOST (and sometimes mini MOST) is the one we used most often. Each of these have their own area of application and corresponding detail and speed of usage..
[Audio] MOST is based on the movement of objects, all of which move in one of two ways: 1. Freely through space when picked up. 2. While maintaining contact with another surface or along a controlled path. When developing MOST, extensive analysis of work measurement data indicated that certain sequences of movement consistently repeat. These sequences form the basis of MOST, and are organized into the following fixed sequence models: • General Move • Controlled Move • Tool Use • Equipment Use.
[Audio] General Move is the manual movement of an object from one location to another, freely through space. Examples include stocking a can on a grocery shelf, putting a washer onto a bolt, placing a label on a box and dropping a part into a bin. The General Move Sequence Model used to identify this movement consists of a fixed series of letters called parameters that represent various sub-activities. Each sequence model in MOST is further broken down into phases to help guide the applicator through analysis. The parameters and phases are as shown here. The order of the sequence model defines the events or actions that take place in the work method. Workplace conditions and the defined work method determine the variation of each parameter —A for Action Distance, for example—which is assigned an index value (0, 1, 3, 6, 10, etc.) taken from a MOST data card. To convert the formula to time, the index values are added together and multiplied by 10 to get the Time Measurement Units (TMU). For example: An associate bends to get a heavy case from the bottom bay of a racking system and then walks three steps to put the case on a pallet. This is shown in MOST as: A1 B6 G3 A6 B0 P1 A0 (1+6+3+6+1+0=17) 17 X 10 = 170 TMU or 6.12 seconds..
[Audio] Controlled Move describes the manual displacement of an object over a 'controlled' path. In other words, either movement of the object is restricted in at least one direction by contact with or attachment to another object, or the nature of the work demands that the object be deliberately moved along a specific or controlled path. Examples include pushing a grocery cart, flipping a switch, sliding a box on a conveyor, opening and closing a tool box or copier lid, and pulling a lever to actuate a machine. The Controlled Move Sequence Model is similar to General Move, but with three different parameters. For example: After placing a check in a register drawer, a clerk reaches to contact the drawer and pushes it back into the register by seating it in place. This is shown in MOST as: A1 B0 G1 M3 X0 I0 A0 (1+1+3=5) 5 X 10 = 50 TMU or 1.80 seconds..
[Audio] The Tool Use Sequence Model covers the use of hand tools for such activities as fastening or loosening, cutting, cleaning, measuring and writing, as well as certain additional activities requiring mental processes, such as reading and inspecting. Examples include cutting open a box with a knife, fastening a nut with a wrench, reading three words from a purchase order and wiping a surface with a cloth. The Tool Use Sequence Model uses all of the parameters from the General Move Sequence Model, as well as one of seven new parameters, used to identify the tool action. For example: An operator grasps a small ratchet six steps away, walks back to the work area and loosens a nut with eight wrist turns. The ratchet is laid aside within reach. This is shown in MOST as: A10 B0 G1 A10 B0 P3 L16 A1 B0 P1 A0 (10+1+10+3+16+1+1=42) 42 X 10 = 420 TMU or 15.12 seconds..
[Audio] The Equipment Use Sequence Model contains values for such administrative activities as using a keyboard and keypad, stapling, stamping and filing. Examples include stapling two receipts together, fi ling a report in a filing cabinet, clicking a computer mouse, stamping the date on a check and totaling numbers on a keypad or adding machine. Equipment Use follows the same sequence model format as Tool Use, but with three different parameters, and was developed for administrative work in any industry. For example: An associate walks five steps to a computer terminal and enters her four-digit personal identification number to access a software system. This is shown in MOST as: A0 B0 G0 A10 B0 P1 K3 A0 B0 P0 A0 (10+1+3=14) 14 X 10 =140 TMU or 5.04 seconds..
[Audio] MOST can be applied to any type of work for which a method can be defined and described, and may be used to determine labor requirements, Define and control labor costs set goals, plan and schedule work, establish a baseline for continuous improvement..
[Audio] The time required by a qualified worker, working at a pace that is ordinarily used by workers when capably supervised to complete a task by following a prescribed method and without interruptions. The result of a MOST analysis is a normal time. Adding allowances to the normal time constitutes a time standard. NORMAL TIME = MANUAL TIME + PROCESS TIME The normal time is the basic work content of a job or process which can be defined as the sum of Manual time (Hand) and Process Time (Machine) An Allowance, or PF&D, is given to take care of personal needs (P), fatigue or rest time (F), and minor delays (D) Normally this is mentioned as % of the basic work content or the Normal time. But in case of Man-Machine environment there is no Fatigue % applied for the automated process. (please check the Man-Machine Training module for more details) This Allowance is necessary to get the Standard Time which a normal operator can achieve on regular basis under normal operational conditions. So the standard time is the Normal Time + PF&D Allowances The way to define the correct PF&D % will be explained in a separate training module..
