في مجال تقدير التكلفة والتحكم فيها، فإن فهم الوقت اللازم لإنجاز مهام معينة أمر بالغ الأهمية. يعتبر قياس العمل، وهو نهج منهجي لتحليل وتحديد كمية متطلبات العمل، أداة حيوية في هذه العملية. ويشمل ذلك تطوير معايير وقت العمل، وهي معايير تُمثل الوقت الذي يحتاجه عامل ماهر لأداء مهمة معينة أو مجموعة من المهام تحت ظروف محددة.
جوهر قياس العمل
ينغمس قياس العمل في تعقيدات عمليات العمل، لتحديد أكثر الطرق كفاءة ووضع مخصصات زمنية دقيقة لكل خطوة. توفر هذه العملية العديد من الفوائد:
طرق قياس العمل
تُستخدم العديد من التقنيات المحددة عادة لقياس العمل:
التحديات والاعتبارات
بينما يوفر قياس العمل مزايا كبيرة، من الضروري معالجة التحديات المحتملة:
الاستنتاج
يُعد قياس العمل عنصرًا أساسيًا في تقدير التكلفة والتحكم الفعالين. من خلال تحديد كمية متطلبات العمل بدقة، يُمكن للشركات اتخاذ قرارات مستنيرة، وإدارة التكاليف بشكل فعال، وضمان تعويض عادل لموظفيها. من خلال اختيار تقنيات قياس العمل المناسبة ومعالجة التحديات المحتملة، يمكن للمؤسسات الاستفادة من هذه الأداة القوية لتعزيز الكفاءة والإنتاجية والربحية.
Instructions: Choose the best answer for each question.
1. Which of the following is NOT a benefit of work measurement?
a) Accurate cost estimation
This is a benefit of work measurement.
b) Effective labor control
This is a benefit of work measurement.
c) Increased employee morale
While work measurement can contribute to a fair work environment, it's not directly focused on increasing employee morale.
d) Enhanced planning and scheduling
This is a benefit of work measurement.
2. What is the primary objective of work measurement?
a) To identify the most skilled workers in a company.
This is not the primary objective of work measurement.
b) To establish labor-time standards for specific tasks.
This is the primary objective of work measurement.
c) To eliminate all inefficiencies from work processes.
While work measurement aims to improve efficiency, it doesn't aim to eliminate all inefficiencies.
d) To increase worker productivity by setting unrealistic targets.
This is not a valid objective of work measurement.
3. Which of the following methods involves observing a worker at random intervals throughout the day?
a) Time Study
Time study involves continuous observation.
b) Work Sampling
This is the correct method.
c) Predetermined Time Systems (PTS)
PTS uses pre-established time values, not random observation.
d) Historical Data Analysis
Historical data analysis relies on past records, not real-time observation.
4. What is a potential challenge associated with work measurement?
a) The ability to establish clear and concise time standards.
While establishing clear time standards can be challenging, this is not a potential challenge specifically associated with work measurement.
b) Resistance to change from workers.
This is a potential challenge of work measurement.
c) The lack of reliable historical data for analysis.
This is a potential challenge of work measurement, specifically for historical data analysis.
d) All of the above.
This is the correct answer.
5. Which of the following best describes the role of work measurement in cost control?
a) It helps identify the most expensive tasks.
While work measurement can help identify tasks that consume more time and resources, it's not its primary role in cost control.
b) It allows for accurate prediction of labor costs.
This is the correct answer.
c) It ensures all tasks are completed within the shortest possible time.
While work measurement aims for efficiency, it doesn't always focus on completing tasks in the shortest time.
d) It eliminates all unnecessary costs associated with labor.
While work measurement helps to optimize labor costs, it doesn't eliminate all unnecessary costs.
Scenario: A small manufacturing company produces custom-made wooden furniture. They are currently developing a new line of dining tables and want to estimate the time and cost required to produce each table.
Task: Using the information below, apply the concepts of work measurement to estimate the time required to build one dining table.
Information:
Exercise:
1. Average Time for Each Task: * Cutting wood: 32 minutes * Sanding: 17 minutes * Assembly: 48 minutes * Finishing: 22 minutes 2. Allowance Factor: * Total observed time: 32 + 17 + 48 + 22 = 119 minutes * Allowance factor: 119 minutes * 0.15 = 17.85 minutes 3. Standard Time: * Standard time: 119 minutes + 17.85 minutes = 136.85 minutes (approximately 2 hours and 17 minutes). 4. Potential Challenges: * **Variations in Wood Quality:** The time required for cutting and sanding might vary depending on the quality and hardness of the wood. * **Complexity of Designs:** If the table designs become more intricate, the assembly and finishing times may increase. * **Worker Skill Level:** Different workers may have varying levels of skill and efficiency, leading to inconsistencies in performance and time requirements. * **Subjectivity of Time Study:** The observer's judgment can influence the recorded times, potentially leading to biased results.
