What is Hourly Production Target
An hourly production target is the number of pieces a line should produce every hour. It is derived from line capacity, SMV, operator count, and efficiency. A wrong target causes either stress or complacency. A well-set target motivates the team and drives output.
How to Calculate Hourly Target
Target equals machines times 60 times efficiency divided by SMV. For example, 30 machines, 60 minutes, 65 percent efficiency, SMV 4 minutes. Target equals 30 times 60 times 0.65 divided by 4 equals 292.5 pieces per hour.
Practical Example 1 — Basic Calculation
A line has 25 machines, runs 60 minutes per hour, has 70 percent planned efficiency, and the style SMV is 5. Target is 25 times 60 times 0.70 divided by 5 equals 210 pieces per hour.
Practical Example 2 — Style Change
A new style has SMV of 6. The same line now has a target of 25 times 60 times 0.70 divided by 6 equals 175 pieces per hour. If the target is not updated, the team will miss it and lose morale.
Practical Example 3 — Daily Aggregation
If the line has 8 working hours and a 15-minute lunch plus 10-minute break, effective hours are 7.4. Daily target is 210 times 7.4 equals 1554 pieces.
Practical Example 4 — Buffer
During ramp-up of a new style, use 80 percent of the calculated target for the first 2 days, then rise to full target. This protects morale and reduces false alarms.
Factors That Affect Hourly Target
SMV, machine count, operator count, absenteeism, machine downtime, material flow, style complexity, and skill level. All must be included in the target setting.
How to Communicate the Target
Post the target on a visible board with hourly production tracking. Update the board every hour. Recognize lines that hit the target. Discuss misses in the hourly meeting. Use the board as a visual management tool, not a punishment tool.
Common Mistakes
Using theoretical efficiency instead of historical. Not adjusting after style change. Setting targets that are too high to motivate. Setting targets that are too low to be useful. Not tracking hourly output. Not explaining the target to operators.
When to Use It
Hourly targets are set at the start of every shift and reviewed hourly. They drive daily output, motivate teams, and expose bottlenecks. They are a core tool for line supervisors and IE teams.
