## Execution Steps

### Step 1: Cost Baseline and Waterfall Analysis

Build the cost waterfall from revenue to operating profit:

**Cost Waterfall Structure:**

```
Revenue                              $[X]    100.0%
  (-) COGS - Materials               $[X]     [X]%
  (-) COGS - Direct Labor            $[X]     [X]%
  (-) COGS - Manufacturing Overhead  $[X]     [X]%
  = Gross Profit                     $[X]     [X]%
  (-) Sales & Marketing              $[X]     [X]%
  (-) R&D / Product Development      $[X]     [X]%
  (-) G&A / Corporate Overhead       $[X]     [X]%
  (-) Distribution & Logistics       $[X]     [X]%
  (-) IT & Technology                $[X]     [X]%
  (-) Facilities & Real Estate       $[X]     [X]%
  (-) Other Operating Costs          $[X]     [X]%
  = EBITDA                           $[X]     [X]%
  (-) D&A                            $[X]     [X]%
  = EBIT                             $[X]     [X]%
```

Compare each line to:
- Prior year (trend)
- Budget (variance)
- Peer benchmark (gap)

Identify the top 5 cost lines with the largest benchmark gap — these are the priority targets.

### Step 2: Cost Driver Tree Decomposition

For each priority cost area, build a driver tree that breaks cost into controllable components:

**Example Driver Tree (Labor Cost):**
```
Total Labor Cost
  = Headcount x Average Cost per Head
    Headcount = Volume x (Labor Hours / Unit) / (Available Hours x Productivity)
    Avg Cost = Base Salary + Benefits + Overtime + Temp/Contract
      Base Salary = f(grade mix, location mix, tenure)
      Benefits = f(plan design, utilization, vendor costs)
```

**Example Driver Tree (Materials Cost):**
```
Total Materials Cost
  = Volume x Material Cost per Unit
    Volume = f(demand, yield loss, scrap)
    Cost/Unit = Price x (1 + Waste%) x (1 + Freight%)
      Price = f(commodity index, supplier negotiations, specs)
      Waste% = f(process capability, material quality, operator skill)
```

For each cost area, identify:
- Which drivers are **controllable** vs. **structural**
- Which drivers have the highest **sensitivity** (1% change in driver = $X impact)
- Which drivers are **trending unfavorably** and why

### Step 3: Zero-Based Budgeting (ZBB) Analysis

Apply ZBB thinking to overhead and SG&A costs:

**ZBB Categorization:**

| Category | Definition | Treatment |
|----------|-----------|-----------|
| **Lights-on** | Minimum cost to keep operations running at current level | Challenge but protect |
| **Growth** | Costs directly tied to revenue growth initiatives | Validate ROI; fund selectively |
| **Compliance** | Regulatory, legal, safety requirements | Validate necessity; optimize delivery |
| **Discretionary** | Nice-to-have; not tied to revenue or compliance | Eliminate unless ROI proven |
| **Legacy** | Costs from prior decisions no longer relevant | Eliminate; exit contracts |

**ZBB Deep-Dive Template (per cost center / function):**

| Cost Element | Current Spend ($) | Lights-On ($) | Growth ($) | Compliance ($) | Discretionary ($) | Savings ($) | Savings % |
|-------------|-------------------|--------------|-----------|---------------|-------------------|------------|-----------|
| Personnel | | | | | | | |
| Travel | | | | | | | |
| Professional services | | | | | | | |
| Software / subscriptions | | | | | | | |
| Facilities | | | | | | | |
| Other | | | | | | | |
| **Total** | **$[X]** | **$[X]** | **$[X]** | **$[X]** | **$[X]** | **$[X]** | **[X]%** |

### Step 4: Activity-Based Costing Analysis

For complex cost structures, apply ABC to understand true cost allocation:

1. **Identify activities** — list all significant activities performed by each function
2. **Assign costs to activities** — allocate personnel, technology, and overhead to each activity
3. **Identify cost drivers** — what drives the volume of each activity
4. **Calculate cost per activity unit** — cost / volume of driver
5. **Assign to cost objects** — allocate activity costs to products, customers, or channels

**Key ABC Insights to Extract:**
- Which products / customers are **truly profitable** vs. subsidized
- Which activities are **non-value-adding** (cost without customer benefit)
- Where **cross-subsidies** exist (one BU absorbing another's costs)
- Which activities have **scale economies** not yet captured (consolidation opportunity)

### Step 5: Benchmarking Analysis

Compare cost structure to relevant peers:

| Cost Metric | Company | Peer 25th %ile | Peer Median | Peer 75th %ile | Gap to Median |
|------------|---------|---------------|-------------|---------------|---------------|
| COGS % of revenue | | | | | |
| Gross margin % | | | | | |
| SG&A % of revenue | | | | | |
| R&D % of revenue | | | | | |
| EBITDA margin % | | | | | |
| Revenue per employee | | | | | |
| Overhead ratio | | | | | |
| IT spend % of revenue | | | | | |

**Benchmark sources:**
- Public company filings (10-K) for listed peers
- Industry associations and surveys
- Consulting firm benchmark databases
- Analyst reports

**Benchmark gap = Opportunity.** For each gap, determine whether it is:
- **Structural:** Different business model, scale, or geography (partially addressable)
- **Operational:** Execution gap that can be closed (fully addressable)
- **Strategic:** Intentional investment (not a gap — validate return)

### Step 6: Initiative Development — Three Horizons

#### Horizon 1: Quick Wins (0-90 Days)

Characteristics: No capital required, within management authority, low risk, immediate P&L impact.

| Lever | Typical Actions | Savings Range |
|-------|----------------|---------------|
| Discretionary spend freeze | Travel, events, hiring freeze, contractor review | 15-30% of discretionary |
| Contract renegotiation | Volume consolidation, competitive pressure, term extension | 3-10% per contract |
| Demand management | Reduce consumption of internal services, supplies, licenses | 5-15% |
| Payment term optimization | Extend payables, accelerate receivables | Cash flow, not P&L |
| Price increases | Selective price actions on low-elasticity products | 1-3% revenue lift |
| Organizational quick fixes | Eliminate vacant positions, consolidate duplicative roles | 100% of vacant loaded cost |

#### Horizon 2: Structural Changes (6-18 Months)

Characteristics: Requires planning, may need modest investment, involves organizational change.

| Lever | Typical Actions | Savings Range |
|-------|----------------|---------------|
| Organization redesign | Spans and layers, shared services, offshoring/nearshoring | 10-25% of affected labor |
| Process automation | RPA, workflow automation, self-service portals | 20-40% of process cost |
| Sourcing / procurement | Strategic sourcing, supplier consolidation, make/buy | 5-15% of category spend |
| Footprint rationalization | Consolidate offices, plants, warehouses | 15-30% of facility cost |
| Product rationalization | Eliminate low-margin SKUs, simplify portfolio | 3-8% margin improvement |
| Channel optimization | Shift volume to lower-cost channels | 10-20% of channel cost delta |

#### Horizon 3: Transformational Savings (18+ Months)

Characteristics: Significant investment, fundamental change, high impact but higher risk.

| Lever | Typical Actions | Savings Range |
|-------|----------------|---------------|
| Business model change | Platform shift, outsourcing core functions, vertical integration | 20-40% structural cost change |
| Technology transformation | ERP replacement, cloud migration, AI/ML deployment | 15-30% of technology + process cost |
| Supply chain restructuring | Network redesign, nearshoring, vertical integration | 10-25% of supply chain cost |
| M&A / divestiture | Acquire for scale economies, divest non-core | Deal-specific |

### Step 7: Business Case Development

For each initiative above the materiality threshold, build a structured business case:

**Business Case Template:**

| Element | Detail |
|---------|--------|
| Initiative name | |
| Problem statement | What costs too much and why |
| Proposed solution | What will change |
| Savings type | Cost reduction / Cost avoidance / Cost deferral |
| Gross annual savings | $ |
| Implementation costs (one-time) | $ |
| Ongoing costs (if any) | $ |
| Net annual savings | $ |
| Payback period | Months |
| 3-year NPV | $ |
| Risk level | Low / Medium / High |
| Key risks | |
| Dependencies | |
| Owner | |
| Timeline | Start — Benefit realization date |
| FTE impact | Reduction / Redeployment / None |
| Service level impact | None / Defined trade-off / Requires monitoring |

### Step 8: Risk Assessment — Cutting Too Deep

**Evaluate every initiative against these guardrails:**

| Risk Area | Warning Signs | Guardrail |
|-----------|--------------|-----------|
| **Service quality** | Customer NPS trending down, complaint volume rising | No cuts to customer-facing capacity below demand coverage |
| **Employee morale** | Voluntary turnover exceeding 15%, engagement scores declining | Maintain competitive compensation; communicate transparently |
| **Innovation capacity** | R&D pipeline thinning, time-to-market increasing | Protect minimum viable R&D spend (benchmark to peers) |
| **Compliance** | Audit findings increasing, regulatory risk rising | Never cut compliance-critical roles or processes |
| **Revenue enablement** | Sales pipeline declining, win rates dropping | Validate that cuts don't reduce revenue-generating capacity |
| **Organizational resilience** | Single points of failure, no succession depth | Maintain critical skills redundancy |

**Red flags that indicate over-cutting:**
- Savings exceed 25% of SG&A without structural change (unsustainable)
- More than 2 consecutive years of headcount reduction without process change
- Outsourcing core competencies for short-term savings
- Eliminating all investment / discretionary spend
- Cutting training and development to zero

- [ ] Quick wins are genuinely achievable in < 90 days without capital investment
- [ ] Benchmarks are industry-specific and sourced — not generic or fabricated
- [ ] ZBB categories are applied consistently and "discretionary" is not conflated with "unnecessary"
- [ ] Cost driver trees identify controllable vs. structural drivers
- [ ] Risk of over-cutting is explicitly assessed — service quality, morale, innovation guardrails stated
- [ ] FTE impact is stated for initiatives involving headcount changes
- [ ] Run-rate savings vs. in-year savings are distinguished (partial-year capture)
- [ ] Implementation costs include severance, change management, and technology if applicable
- [ ] Governance structure is defined with clear accountability and cadence
