S&OP Process Design & Implementation

## ROLE
You are an S&OP (Sales & Operations Planning) process architect who has implemented integrated business planning at companies ranging from $100M to $10B+ in revenue. You understand that S&OP is fundamentally a people and process challenge, not just a technology problem. You have driven cross-functional alignment between sales, marketing, operations, finance, and executive leadership.

## OBJECTIVE
Design an S&OP process for [COMPANY] with [REVENUE] annual revenue in the [INDUSTRY] industry. The company has [NUMBER] manufacturing plants, [NUMBER] distribution centers, and sells through [CHANNELS]. Current planning pain points include [ISSUES: demand/supply imbalance, excess inventory, poor forecast accuracy, lack of cross-functional alignment].

## TASK

### Current State Assessment
- Existing planning processes: what planning happens today, by whom, how often?
- Cross-functional alignment: how do sales, operations, and finance currently coordinate?
- Data infrastructure: ERP system, planning tools, spreadsheets, data quality
- Decision-making process: who decides on production, inventory, and allocation?
- Planning horizon: current look-ahead window and review cadence
- Performance gaps: where do planning failures show up (stockouts, excess, cost overruns)?
- Organizational readiness: executive sponsorship, change management needs

### S&OP Process Framework
Monthly cycle with five key meetings:

Step 1 — Data Gathering & Preparation (Week 1)
- Compile actual vs. plan performance for prior month
- Update statistical demand forecast
- Refresh supply chain data: capacity, inventory, supplier lead times
- Prepare variance analysis and exception reports
- Generate initial demand and supply dashboards

Step 2 — Demand Review (Week 2)
- Attendees: demand planning, sales, marketing, product management
- Review statistical forecast with market intelligence overlay
- Incorporate new product launches, promotions, pricing changes
- Capture sales pipeline changes and customer forecasts
- Identify demand risks and opportunities
- Output: unconstrained demand plan by product family and channel

Step 3 — Supply Review (Week 2-3)
- Attendees: supply planning, manufacturing, procurement, logistics
- Assess ability to meet demand plan: capacity, materials, labor
- Identify supply constraints and bottlenecks
- Develop supply scenarios: baseline, upside, downside
- Calculate inventory projections under each scenario
- Output: constrained supply plan with identified gaps and options

Step 4 — Pre-S&OP / Reconciliation (Week 3)
- Attendees: cross-functional managers from demand, supply, finance
- Reconcile demand and supply plans: identify gaps and trade-offs
- Develop decision options for executive review
- Financial translation: revenue, margin, inventory investment, cash flow
- Scenario analysis: what-if modeling for key decisions
- Output: recommended plan with decision items for executive review

Step 5 — Executive S&OP (Week 4)
- Attendees: CEO/GM, VP Sales, VP Operations, VP Finance, VP Supply Chain
- Review business performance vs. plan and prior year
- Make decisions on open issues from pre-S&OP
- Approve 18-month rolling plan
- Align on assumptions and risks
- Output: authorized operating plan, capital decisions, strategic alignment

### KPI Framework
- Demand plan accuracy: forecast accuracy at product family level
- Supply plan adherence: production plan vs. actual, supplier delivery performance
- Inventory health: days on hand, turns, slow/obsolete percentage
- Customer service: fill rate, on-time-in-full (OTIF), order cycle time
- Financial performance: revenue vs. plan, gross margin, working capital
- Process compliance: meeting attendance, action item completion, on-time publishing

### Implementation Roadmap
- Phase 1 (Months 1-3): Foundation — data cleanup, basic process, pilot with one product line
- Phase 2 (Months 4-6): Expansion — roll out to all product lines, establish cadence
- Phase 3 (Months 7-12): Maturity — integrate financial planning, scenario modeling
- Phase 4 (Year 2): Advanced — predictive analytics, what-if simulation, strategic planning integration
- Change management: training, communication, resistance management
- Quick wins: identify early victories to build momentum and credibility

### Common Pitfalls & Solutions
- Pitfall: S&OP becomes a data review instead of a decision-making forum
- Pitfall: executives skip meetings or delegate to junior staff
- Pitfall: plans are created but not executed
- Pitfall: too much detail drowns the conversation
- Pitfall: finance is not involved until too late
- For each pitfall: specific countermeasures and prevention strategies
