Work Measurement Determines The It Should Take To A Job

Work Measurement: Determining the Time it Should Take to Do a Job

Work measurement is a systematic process used to determine the time it should take a qualified worker to perform a specific task or job under defined conditions. Consider this: it's a cornerstone of effective operational management, enabling organizations to optimize productivity, plan labor requirements, set realistic performance goals, and establish fair compensation systems. Understanding work measurement techniques is crucial for businesses aiming to improve efficiency and maintain a competitive edge. This article provides a comprehensive overview of work measurement, exploring its methods, applications, and the crucial considerations for successful implementation.

What is Work Measurement?

Work measurement, at its core, is about objectively analyzing the time required to complete a task. It goes beyond simple stopwatch timing; it looks at the detailed analysis of each element of a job, factoring in factors such as skill level, effort, working conditions, and allowances for unavoidable delays. The goal isn't to push workers to perform beyond their capabilities but to establish a standard time – a realistic and achievable benchmark for completing the task. This standard time isn't a rigid constraint but a valuable tool for planning, scheduling, and performance evaluation.

Why is Work Measurement Important?

The benefits of effective work measurement are multifaceted:

• Improved Productivity: By identifying inefficiencies and bottlenecks, work measurement helps streamline processes and boost overall output.
• Accurate Costing: Determining the labor cost associated with each task allows for more precise pricing and better budget management.
• Fair Compensation: Standard times provide a basis for equitable wage structures, ensuring that workers are compensated fairly for their efforts.
• Effective Planning and Scheduling: Accurate time estimates are critical for project planning, resource allocation, and efficient scheduling.
• Performance Monitoring and Improvement: Tracking actual performance against standard times facilitates identification of areas requiring improvement and training.
• Capacity Planning: Work measurement provides insights into the capacity of a workforce and helps in workforce planning and recruitment.
• Improved Methods and Processes: Analyzing task times often reveals opportunities for process improvement and simplification.

Methods of Work Measurement

Several methods are employed for conducting work measurement, each with its strengths and weaknesses:

1. Time Study: This is a classic method involving direct observation and measurement of the time taken by a worker to complete a task. A trained time study engineer uses a stopwatch to record the time taken for each element of the job, taking multiple readings to account for variations in performance. This method necessitates detailed job breakdown, careful observation, and the application of appropriate allowances for factors like fatigue, personal needs, and unavoidable delays.

Steps in Conducting a Time Study:

• Select the job to be studied: Choose a job that is representative and stable.
• Break the job into elements: Divide the job into smaller, distinct, measurable elements.
• Record the time for each element: Use a stopwatch to record the time for each element, taking multiple readings.
• Rate the performance: Assess the worker's performance relative to a standard.
• Calculate the normal time: Adjust the observed time to account for the worker's performance rating.
• Add allowances: Account for personal needs, fatigue, and unavoidable delays.
• Calculate the standard time: The sum of the normal time and allowances.

2. Work Sampling: This statistical technique involves randomly observing a worker's activity over a period of time to determine the proportion of time spent on different tasks. It's particularly useful for jobs with many short, varied elements or where continuous observation is impractical. Work sampling requires careful planning and a statistically significant number of observations to ensure the results are reliable.

3. Predetermined Motion Time Systems (PMTS): These systems, such as Methods-Time Measurement (MTM) and Work Factor (WF), use standardized data to estimate the time required for basic body movements. Analysts break down a job into these basic movements and use pre-established time values for each movement to calculate the overall task time. PMTS offer greater consistency and less reliance on direct observation than time studies, but they require expertise in using the specific system and accurately defining the movements.

4. Standard Data: This method relies on compiling historical data from previous time studies or PMTS analyses to create a database of standard times for common tasks or elements. New tasks can then be estimated by combining standard data for similar elements. This method is efficient once a substantial database has been developed but requires careful validation of the data's accuracy and relevance.

5. Motion and Time Study: This method combines aspects of time study and motion study. Motion study involves analyzing the movements involved in a job to identify inefficiencies and improve the work method, while time study then measures the time required for the improved method.

Allowances in Work Measurement

Allowances are crucial components of work measurement, accounting for factors that influence the actual time required to complete a task. Common allowances include:

• Personal Needs Allowance: Time for personal needs such as restroom breaks, getting drinks, etc. Typically around 5% of the total work time.
• Fatigue Allowance: Compensation for physical and mental fatigue, varying depending on the job's physical demands and duration.
• Delay Allowance: Accounts for unavoidable delays due to equipment malfunctions, material shortages, or other disruptions.
• Contingency Allowance: A buffer for unforeseen circumstances or variations in task performance.

The specific percentages for each allowance vary depending on the nature of the job, the working conditions, and the company's policies.

Implementing Work Measurement Effectively

Successful work measurement implementation requires careful planning and execution:

• Define clear objectives: Establish what you hope to achieve with work measurement.
• Select appropriate methods: Choose the methods that best suit the nature of the jobs and available resources.
• Ensure proper training: Train personnel involved in the process thoroughly.
• Maintain accurate records: Keep detailed records of all measurements and allowances.
• Regularly review and update: Standard times should be reviewed and updated periodically to reflect changes in technology, processes, or worker skills.
• Involve workers: Engaging workers in the process helps build buy-in and improves the accuracy of the data. Workers often have valuable insights into task efficiency and potential improvements.
• Use the data effectively: Standard times shouldn’t just sit on a shelf. They should be used for planning, scheduling, performance management, and compensation decisions.

Frequently Asked Questions (FAQ)

Q1: Isn't work measurement just about speeding up workers?

A: No. Work measurement aims to establish a realistic standard time for a task, not to push workers beyond their capabilities. The focus is on optimizing processes and ensuring fair compensation based on the actual time required for the job. It should lead to improved efficiency, not worker exploitation.

Q2: How can I deal with variability in task times?

A: Variability is inherent in most tasks. Work measurement methods like time studies address this by taking multiple observations and applying statistical techniques to derive a reliable standard time. Identifying and mitigating the sources of variability (e.g., inconsistent material supply, equipment malfunctions) is also crucial.

Q3: What if my workers resist work measurement?

A: Resistance can arise from concerns about increased workload or perceived unfairness. Addressing these concerns through open communication, clear explanations of the benefits, and worker involvement in the process are essential. Transparency and fair implementation are key to gaining acceptance.

Q4: How often should work measurement be updated?

A: The frequency of updating depends on the rate of change in processes, technology, and working methods. Regular reviews, ideally annually or whenever significant changes occur, are recommended to maintain the relevance and accuracy of standard times.

Conclusion

Work measurement is a powerful tool for enhancing organizational efficiency and productivity. Consider this: by objectively determining the time required for specific tasks, organizations can make informed decisions about resource allocation, compensation, and process improvement. Choosing the right method, incorporating allowances, and fostering collaboration with workers are crucial steps towards successful implementation and achieving its full potential. While the implementation requires careful planning and execution, the benefits of accurate and well-implemented work measurement far outweigh the costs. Through its application, businesses can move beyond guesswork and towards data-driven decision making, optimizing performance and ensuring a sustainable competitive advantage.
