Standard Minute Value (SMV) is a key factor in production planning. It helps measure the time needed to complete a task. Many industries use SMV to improve efficiency. SMV also supports cost control, time management, and worker performance tracking.
What is SMV?
SMV means Standard Minute Value. It is the time needed to produce one unit of work. Engineers calculate SMV based on work content, motion steps, and tool use. This value helps managers set goals for workers and machines.
For example, if a task takes 5 minutes to finish, then the SMV is 5. This gives a clear time target for operators. If a worker takes longer than the SMV, it shows a need for training or process review.
Why Is SMV Important?
SMV supports many production goals. It helps managers set fair targets. It also helps balance workloads on different lines. These benefits make SMV important in textile, automotive, electronics, and food processing sectors.
1. SMV Helps Set Production Targets
Managers use SMV to set output targets for each worker. This helps ensure each person works at a steady pace. Without SMV, workers may overwork or underwork. This creates issues in quality and time.
2. SMV Improves Line Balancing
SMV helps engineers assign equal workloads to each station. This avoids idle time. It also prevents work pile-up at one point. Line balancing improves flow and keeps machines busy.
3. SMV Supports Cost Control
SMV helps in cost planning. If you know how much time a task takes, you can plan labor costs. SMV also helps check if you need more staff or machines.
How to Calculate SMV
Production engineers follow a standard SMV calculator app or Excel sheet. This includes work breakdown, motion study, and applying allowances.
Step 1: Break the Task into Small Steps
Engineers divide the task into small actions. Each step has a start and an end. For example, โpick part,โ โplace part,โ and โpress button.โ
Step 2: Time Each Step
Then, they use a stopwatch or video to time each step. This is called a time study. It shows how long each action takes.
Step 3: Apply Allowances
Not all time is work time. You must add some time for rest, fatigue, and machine delays. This is called an allowance. Most industries add 10% to 20% as standard.
Final Formula:
SMV = Basic Time + Allowance Time
Example: If a task takes 4 minutes and the allowance is 15%, then:
SMV = 4 + (4 ร 0.15) = 4.6 minutes

SMV in Different Industries
Each industry uses SMV differently. But the goal is always to save time and cut costs.
Textile Industry
In garment production, SMV sets goals for sewing, cutting, and packing. A shirt may have an SMV of 30 minutes. This value helps set daily output targets.
Automotive Industry
In vehicle assembly, SMV helps balance the line and reduce idle time. Workers follow time-based steps. This keeps the process smooth and fast.
Electronics Industry
In mobile phone production, each part goes through a timed process. SMV helps in board mounting, testing, and packing.
Food Industry
In food packing, SMV helps speed up tasks like filling, sealing, and labeling. It also helps reduce labor waste.
How SMV Affects Worker Performance
SMV also helps in worker evaluation. If a worker finishes more units than the SMV target, they are more efficient. If they take longer, they need training or support.
1. Fair Performance Rating
Managers use SMV to rate workers. This creates a fair system for reward or bonus.
2. Training Needs
Low performance against SMV may show poor skills or lack of knowledge. Managers can give targeted training.
3. Daily Output Tracking
With SMV, supervisors can track daily output. This keeps the team on track and improves time use.

SMV and Productivity Improvement
Using SMV helps improve overall productivity. It supports faster delivery, better use of machines, and fewer delays.
1. Time Loss Detection
SMV helps find where time is lost. This may be due to waiting, walking, or poor machine setup.
2. Bottleneck Control
If one task has a high SMV, it may block the next task. Engineers can fix this by improving the process or adding help.
3. Continuous Improvement
SMV gives data. Data helps find ways to do work faster and better. This creates a habit of improvement.

Tools for SMV Calculation
Engineers use tools to calculate SMV and manage tasks.
1. Stopwatch
A simple tool for timing manual tasks.
2. Time Study Software
Digital tools give faster and more accurate SMV values.
3. Motion Study Apps
Video apps help record and break tasks into motions.
Final Thoughts
SMV is key to production control. It helps set targets, balance lines, and improve cost and time. Every industry can use SMV to make work faster, smarter, and more cost-effectively.
Production engineers must use SMV in all task planning. It is a simple way to measure time, improve flow, and raise output.
