Workflow

Demand forecast alignment flow

1

Enter baseline forecast

Give sales and supply-chain teams one shared starting number.

2

Bring holidays and seasonal peaks into the forecast.

3

Compare actual sales

When actuals arrive, variance rate is calculated.

4

Review accuracy

Use the error trend to see whether forecasting is improving.

Adoption boundary

Where spreadsheets are enough and where systems help

Supply-chain workbooks are good for aligning decision logic. When data sources, permissions, and reminders grow, move the repeated parts into a system.

Spreadsheet fit

One team aligning quickly

When data volume is small and the rule is still being tested, a workbook is the fastest shared layer.

  • Single team
  • Manual review
  • Short pilot
Partial systemization

More alerts and approvals

When the same result needs routing or approval, systemize the key checkpoints first.

  • Automatic alerts
  • Approval flow
  • Owner tracking
Full systemization

Cross-warehouse coordination

When data sources, permissions, and update frequency grow, move data and workflow into a shared system.

  • Multiple sources
  • Access control
  • Process history

FAQ

Supply-chain template FAQ

Review the inputs and operating boundary before downloading.

How should the seasonal factor be set?

Use historical same-month demand divided by average demand, or start with a business estimate.

What if actual sales are zero?

The workbook avoids division by zero and leaves the error rate blank when actual sales are blank or zero.

Is higher forecast accuracy always enough?

Higher is usually better, but inventory cost and stockout risk still need to be considered.
