Service Level Investment Framework (SLIF) — Complete Bundle

$89.00

Your service level targets are probably wrong. Not because your team isn't capable — because no one has ever given them a process to set them on purpose.

The SLIF Complete Bundle is the full system: the five-step methodology, the analytical workbook that runs the numbers, and the reference framework — everything you need to move from arbitrary targets to defensible, financially grounded service level decisions.

What's in the Bundle (4 Files)

1. DecisioTools Service Level Investment Analyzer — Excel Workbook

The analytical engine behind the framework. Eight purpose-built sheets that take you from raw inputs to a fully costed service level recommendation.

• Instructions & Methodology — A client-facing guide to the concepts behind every calculation. Share it with anyone who needs to trust the numbers
• Executive Dashboard — One-page summary of key figures: current vs. target service level, inventory investment required, and the financial impact of moving between levels
• Assumptions & Inputs — Every calculation traces back here. Demand inputs, lead time, cost of capital, holding cost rate — all in one place, all editable
• CSL – Fill Rate Calculator — Shows exactly where Cycle Service Level and Fill Rate diverge, and why the gap matters for how you set targets
• Safety Stock Calculator — Calculates required safety stock at any service level, with demand and lead time variability built in
• Scenario Comparison — Side-by-side comparison of up to four service level scenarios with full inventory cost and working capital impact
• Service Level Economics — The knee-of-the-curve analysis: where each additional point of service level costs disproportionately more inventory investment
• Lookup Data — Z-score and service factor reference tables that power the calculations

2. SLIF Complete Guide — PDF

The full five-step methodology with fillable worksheets for Steps 1 and 2, and exact tab-by-tab guidance for using the Analyzer workbook in Steps 3 and 4.

• All five steps in full: Segment → Align → Quantify → Evaluate → Govern
• Fillable segmentation worksheet — run it against your own top 15–20 products
• Target-setting worksheet for Step 2, with rationale and owner columns for every segment
• The full Quantify and Evaluate methodology — including why CSL and Fill Rate diverge and where the knee of the curve typically sits
• The Governance step most companies skip — and why they regret it eighteen months later
• A one-page summary you can put in front of a leadership team

3. SLIF Framework Reference — PDF

A concise one-page reference card covering the five-step framework, key definitions, and the decision logic behind each step. Keep it on your desk or share it with your team before an S&OP review.

4. SLIF Free Introduction — PDF (Bonus)

The standalone introduction included for completeness — useful for onboarding a new team member or sharing the framework overview with a stakeholder who doesn't need the full workbook.

The Five-Step Framework

Step	Question	Output
1 · Segment	Which products and customers actually matter?	SKU segments: Strategic, Core, Standard, Tail
2 · Align	What service level does each segment need?	Target CSL or Fill Rate by segment, with rationale
3 · Quantify	What does that service level cost?	Safety stock and inventory investment by scenario
4 · Evaluate	Is the cost worth the improvement?	Knee-of-the-curve analysis, go/no-go recommendation
5 · Govern	How do we keep this current?	Review cadence, owner, trigger conditions

Who This Is For

Supply chain directors and VPs who need to defend inventory investment decisions to finance and the board. Inventory and demand planners who are being held to service level KPIs they didn't set. S&OP and IBP leaders who want a structured, repeatable process for service level reviews. Anyone who has ever been told to "improve service" without being told what it would cost.
