An Hour-by-Hour Board is a visual management tool that compares expected output with actual output in short operating intervals.
The interval may be one hour, 30 minutes, or another practical period.
The goal is to make production gaps visible while there is still time to respond.
Why short intervals matter
A daily output number can hide when the problem occurred.
Suppose a line produces 920 units against a target of 1,000.
The daily result shows an 80-unit gap.
An Hour-by-Hour Board may show that most of the loss occurred between 10:00 and 11:00 because of a material shortage and again between 14:00 and 15:00 because of a minor equipment fault.
That information is more actionable.
Define the expected output
The board needs a realistic interval target.
The target should connect to demand, planned operating time, and Takt Time where appropriate.
If the target is arbitrary, the visual signal will not help the team manage the process.
Record actual performance
At each interval, record:
- expected output;
- actual output;
- gap;
- reason for the gap;
- immediate action.
The board should be simple enough for the team to update without creating administrative burden.
Focus on abnormal conditions
A good board directs attention to gaps.
If actual output matches the expectation, little discussion is needed.
If the process misses the target, ask:
- What happened?
- Is the issue contained?
- Can the team recover?
- Does the problem require escalation?
- Is the problem recurring?
This makes the board part of the Daily Management System.
Use reason codes carefully
Reason codes can help identify recurring losses.
Examples include:
- material shortage;
- breakdown;
- quality;
- changeover;
- staffing;
- blocked downstream;
- planned stop.
Do not create so many codes that employees spend more time classifying losses than solving them.
Connect to tiered escalation
Tiered Daily Meetings can use Hour-by-Hour information to identify issues that need broader support.
Frontline teams should solve what they can.
Higher levels should remove barriers that cannot be resolved locally.
Avoid blaming the operator
The board should make process problems visible, not create pressure to hide gaps.
If teams believe every red interval will be treated as failure, the data will become unreliable.
The stronger culture asks what prevented the process from performing as expected.
Common mistakes
Setting unrealistic targets, recording gaps without reasons, using the board only at the end of the shift, allowing chronic problems to repeat without escalation, and treating red performance as an employee problem are common mistakes.
Practical sequence
- Define the operating interval.
- set expected output.
- record actual output.
- calculate the gap.
- capture the main reason for misses.
- take immediate containment action.
- escalate barriers when required.
- review recurring losses.
- connect chronic issues to problem solving.
- adjust standards when the process changes.
The practical lesson
An Hour-by-Hour Board shortens the time between a performance gap and a management response.
That makes daily management more proactive and less dependent on end-of-shift surprises.
