How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Required quantity | units | Quantity required by the deadline |
| Cycle time | min/unit | Cycle time per unit per resource |
| Parallel resources | resources | Parallel resources available |
| Hours / day | hr | Working hours per day |
| Working days | days | Working days until the deadline |
| Efficiency | % | Demonstrated efficiency |
What each input means
Open an input to see what it is, its units, the worked example and the common mistakes, with a small diagram.
What this means: Required quantity
- What it is
- The number of units that must be finished by the deadline.
- Units and format
- Enter a number in units: a count of units. The form accepts 0 units or more.
- Example
- The form opens with 5000 units as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Days needed rise in proportion; the buffer falls unit for unit.
- Get it right
- Add an allowance for expected scrap if the quantity is for good units.
What this means: Cycle time
- What it is
- The time one resource takes to complete one unit, measured at the constraint step of the process.
- Units and format
- Enter a number in min/unit: min/unit. The form accepts 0.01 min/unit or more.
- Example
- The form opens with 3 min/unit as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Output per day falls in proportion as cycle time grows.
- Get it right
- Enter minutes per unit on one resource, not the combined rate of all resources.
What this means: Parallel resources
- What it is
- The number of machines, cells or people who can each make the product at the same time, so their output adds together.
- Units and format
- Enter a number in resources: resources. The form accepts 1 resources or more.
- Example
- The form opens with 2 resources as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Output per day rises in proportion.
- Get it right
- Count only resources free for this job for the whole period.
What this means: Hours / day
- What it is
- The hours each resource is scheduled to work on a working day, including any planned overtime.
- Units and format
- Enter a number in hr: hours. The form accepts 0 hr to 24 hr.
- Example
- The form opens with 8 hr as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Output per day rises in proportion.
- Get it right
- Use scheduled hours; efficiency then takes off the time lost to stops and slow running.
What this means: Working days
- What it is
- The number of working days between now and the deadline, leaving out weekends, public holidays and shutdowns.
- Units and format
- Enter a number in days: days. The form accepts 0 days or more.
- Example
- The form opens with 15 days as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Deliverable quantity rises in proportion; days needed does not change.
- Get it right
- Allow for time after production, such as inspection, packing and dispatch, before the due date.
What this means: Efficiency
- What it is
- The share of scheduled hours that turns into good output after breakdowns, changeovers, slow running and scrap, from recent performance.
- Units and format
- Enter a number in %: percent: the number is read as a percentage, so type 8 for 8 %. The form accepts 1% to 100%.
- Example
- The form opens with 85% as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Output per day rises in proportion.
- Get it right
- Use demonstrated efficiency, not a target. Type the percentage (85 for 85 %).
Method and formulas
- Output per day = hours × 60 × resources × efficiency ÷ cycle
- Deliverable = output per day × days
- Days needed = quantity ÷ output per day
Limitations
- Machine time only; materials and people must be confirmed
Typical uses
- Confirming customer delivery dates
- Planning overtime or extra shifts
Who it is for
- Planners
- Customer service and sales
What you get
- ACHIEVABLE or NOT ACHIEVABLE
- Deliverable quantity, buffer and days needed
Interpreting the result
- Less than 10% spare is fragile; confirm materials before promising the date
