Act as a senior FP&A professional facilitating reconciliation between top-down targets and bottom-up forecasts.

Analyze and reconcile the two planning views provided below.

Organization:
{{organization_name}}

Planning period:
{{planning_period}}

Top-down targets:
{{top_down_targets}}

Bottom-up forecast:
{{bottom_up_forecast}}

Assumptions and drivers:
{{assumptions_drivers}}

Strategic and operational constraints:
{{constraints}}

Analysis requirements:

1. Confirm that both views use consistent:
   - periods;
   - currencies;
   - units;
   - accounting definitions;
   - scope;
   - organizational structure; and
   - treatment of eliminations.
2. Build a reconciliation bridge from the top-down target to the bottom-up forecast.
3. Quantify variances by:
   - revenue;
   - volume;
   - price;
   - mix;
   - margin;
   - headcount;
   - productivity;
   - OPEX;
   - capital expenditure;
   - working capital;
   - cash flow; and
   - other material drivers.
4. Separate variances caused by:
   - different assumptions;
   - timing;
   - scope;
   - methodology;
   - ownership;
   - strategic ambition;
   - operating constraints;
   - data quality; and
   - unidentified residuals.
5. Identify where top-down expectations are unsupported by current operational capacity or evidence.
6. Identify where bottom-up forecasts may contain conservatism, slack, duplicated cost, omitted opportunity, or inconsistent assumptions.
7. Create a challenge log showing:
   - issue;
   - owner;
   - evidence;
   - proposed adjustment;
   - decision required;
   - deadline; and
   - status.
8. Develop reconciliation options:
   - accept bottom-up forecast;
   - enforce top-down target;
   - phased convergence;
   - targeted initiatives;
   - scope change; or
   - revised assumptions.
9. For each option, assess feasibility, financial impact, timing, risk, and accountability.
10. Do not force an artificial reconciliation by using unsupported balancing items.
11. Do not invent savings, growth, capacity, or management commitments.
12. Clearly identify unresolved gaps and decisions requiring executive intervention.

Present the result as:
{{output_format}}

Include:
- comparability check;
- reconciliation bridge;
- variance table;
- assumption-gap analysis;
- operational feasibility assessment;
- challenge log;
- reconciliation options;
- recommended actions;
- ownership and deadlines;
- unresolved decisions; and
- executive summary.

Customization Variables

Replace each variable shown in double curly brackets with accurate information from your own professional context.

{{organization_name}}

Organization Name

Required

Example: Example: Atlas Regional Operations

Enter the organization, region, or business unit being reconciled.

{{planning_period}}

Planning Period

Required

Example: Example: FY2027 budget

Specify the budget or forecast period.

{{top_down_targets}}

Top-Down Targets

Required

Example: Paste leadership targets for revenue, margin, cost, cash flow, capex, and strategic outcomes.

Include target definitions, scope, and key assumptions.

{{bottom_up_forecast}}

Bottom-Up Forecast

Required

Example: Paste operational forecasts by business unit, product, department, or geography.

Provide detailed operational forecasts and supporting calculations.

{{assumptions_drivers}}

Assumptions and Drivers

Required

Example: List volume, price, headcount, productivity, cost, timing, and capacity assumptions for both views.

The reconciliation depends on understanding which assumptions differ.

{{constraints}}

Strategic and Operational Constraints

Optional

Example: Describe capacity, contracts, hiring, supply, systems, funding, and regulatory constraints.

Constraints help assess whether targets are operationally achievable.

{{output_format}}

Output Format

Required

Choose the format appropriate for analysis, workshops, or executive decisions.

📄

Context

Provides top-down targets, bottom-up forecasts, assumptions, drivers, constraints, and period.

🎯

Task

Requires a quantified reconciliation and decision-oriented challenge process.

🛡️

Constraints

Prevents forced balancing, invented savings, unsupported growth, and hidden unresolved gaps.

📚

Output Structure

Requires bridges, variance analysis, feasibility, challenge logs, options, ownership, and decisions.

🔑

Input Variables

Organization, planning period, top-down targets, bottom-up forecast, assumptions, constraints, and output format.

Improve the Result

Customization Tips

  1. Ensure both views use the same periods, scope, currency, and accounting definitions.
  2. Provide driver-level detail rather than only total variances.
  3. Document who owns each assumption and what evidence supports it.
  4. Avoid balancing items that conceal unresolved differences.
  5. Use the challenge log during budget workshops and update it after management decisions.
