Analyze a Method to Understand How the Assembly Job Is Being Executed
This Individual Project (IP) builds upon your work in Units 1, 2, and 3. For guidance with this project, use Chapter 7 of your textbook, which provides an overview of work design and measurement. The lean operations system strategy has been in operation for 3 months at Your Furniture Company. Recently, operations managers have received complaints from the company’s distribution division that customer orders for dining room tables are delayed due to a backup in the production assembly area. The assembly team consists of 30 members, each assembling a table from start to finish from the cut pieces provided through upstream production.
The operations management team decides to analyze a method to understand how the assembly job is being executed and apply work measurement to determine a standard for how long the assembly job should take. This standard time will help in assessing if changes are needed to current capacity planning for the assembly line. For this assignment, you should introduce methods analysis and work measurement as related to operations management. Then, examine how each step in the methods analysis procedure can be used to improve the efficiency of the dining table assembly operation.
The methods analysis procedure includes the following steps (Stevenson, 2020):
- Identify the operation to be studied, gathering pertinent facts about tools, equipment, materials, and involving discussions with the operator and supervisor for existing jobs.
- Study and document the current method using process charts.
- Analyze the job and propose new methods.
- Install the new methods and follow up to ensure improvements are achieved.
Based on the steps that a Dining Table Assembler (DTA) executes, formulate a stopwatch time study strategy to establish a standard time for assembly tasks. Update the operations management team and CEO on whether the assembly time meets the company's goal of 35 minutes. If not, make efficiency improvement recommendations. The DTA process involves constructing the table from cut pieces, including assembling parts, attaching casters, securing the MDF, joining supports, attaching the top, and checking for defects. Data provided includes average observed times for each process step from 30 DTAs, as well as performance rating and allowance factors.
Using this data, assess whether the current assembly process meets the standard time goal. Calculate total average observed time, normal time, and standard time based on the given parameters. If the assembly is not meeting the goal, recommend steps for management to improve efficiency. The conclusion should summarize the key points discussed regarding research methods, sampling analysis, and performance assessment.

Introduction to Methods Analysis and Work Measurement in Operations Management
Methods analysis and work measurement are fundamental components of operations management, pivotal for optimizing productivity and efficiency within manufacturing processes. Methods analysis involves systematically studying the procedure of a task to identify inefficiencies and opportunities for improvement (Stevenson, 2020). Work measurement, on the other hand, quantifies the time required to perform a task, establishing a standard time that guides scheduling, staffing, and process improvements. These techniques are integral in designing work systems that balance capacity with demand, eliminate waste, and enhance overall operational performance (Heizer, Render, & Munson, 2017).
In the context of lean operations, these analytical tools help identify non-value-added activities and streamline workflows, thus reducing cycle times and increasing throughput (Womack & Jones, 2003). They are especially relevant in assembly operations, where precise timing and efficient sequence of tasks directly influence production capacity and lead times (Khanna, 2019). Applying methods analysis and work measurement can lead to systematic improvements that meet customer demands without incurring unnecessary costs.
Application of Methods Analysis to the Dining Table Assembly Job
The DTA job, comprising steps such as building uprights, connecting supports and legs, attaching casters, securing MDF, joining supports, attaching the top, and inspecting for defects, can be effectively studied through methods analysis. Initially, the operation needs to be identified, with all tools, materials, and resources documented. Input from the operator and supervisor is critical to understanding the nuances of each task and potential bottlenecks (Stevenson, 2020).
Using process charts such as flow or process maps, the current method can be visually documented, revealing redundant or non-value-added steps. For example, if the attachment of casters involves unnecessary adjustments or repositioning, it can be streamlined. By analyzing each step, opportunities to simplify or combine tasks are identified, reducing overall time and fatigue.
Work Measurement Strategy Using Stopwatch Time Study
The stopwatch time study involves observing multiple repetitions of the assembly process, recording the time taken for each task across 30 DTAs. The average observed time offers a basis for calculating the normal time, accounting for the worker’s performance rating (PR). The formula is:
Normal Time = Average Observed Time × Performance Rating (PR)
Given the average observed times for tasks, the total observed time is calculated by summing individual task times: 30 + 5 + 2 + 4 + 2 + 1 + 1 = 46 minutes per table, per DTA. Adjusting for performance rating:
Normal Time = 46 minutes × 0.77 = 35.42 minutes
Adding a predetermined allowance factor (AF) of 15% for fatigue and delays, the standard time is computed as:
Standard Time = Normal Time × (1 + AF) = 35.42 × 1.15 ≈ 40.73 minutes
Since the company's goal is 35 minutes, this indicates the current process exceeds the target, signaling inefficiency that warrants improvement.
Performance Evaluation and Recommendations for Efficiency Improvements
The analysis suggests the current standard time of approximately 40.73 minutes surpasses the goal of 35 minutes. Management should explore methods to reduce assembly time through several targeted interventions.
- Process Reengineering: Simplify assembly steps by redesigning the workflow or tool ergonomics—such as using powered tools to speed up fastening procedures.
- Worker Training: Enhance operator skills through training programs to improve speed without compromising quality.
- Standardization of Tasks: Implement standardized work procedures to minimize variations and identify the most efficient methods.
- Concurrent Operations: explore the possibility of performing steps in parallel, if feasible, to reduce total cycle time.
- Equipment Upgrades: Invest in more advanced machinery or fixtures that facilitate quicker assembly.
- Motivational Incentives: Incorporate incentive schemes to motivate workers to meet time standards.
Monitoring the implementation of these improvements through subsequent time studies is essential to ensure the assembly time aligns with the 35-minute goal. Continuous feedback and adaptation can sustain efficiency gains over time.
Conclusion
Effective methods analysis and work measurement are key to enhancing assembly line productivity. The stopwatch time study provides a quantifiable basis for establishing standard times, highlighting areas for operational improvements. Although current practices exceed the desired time frame, strategic interventions focused on process redesign, skill enhancement, and equipment upgrades can bridge this gap. Ongoing evaluation ensures the assembly process remains aligned with lean principles and customer expectations, ultimately supporting the company's competitive positioning.
