Cybex The Quarterly
Retail Advisory · Volume 1 · Spring 2026

A retail advisory practice, built on delivery.

Cybex serves retail leadership teams — CEOs, CFOs, CIOs, and chief merchants — on the decisions that move enterprise value. Our work is diagnostic-led, evidence-grounded, and accountable to quantified outcomes. We bring the methodological rigour of a Big Four advisory practice, combined with the hands-on delivery depth of an operator.

Phase 01 Diagnose

Diagnostic & Value Sizing

A structured assessment of the retail P&L, operating model, and data estate. We build a MECE value map: where margin is lost, where working capital is trapped, and where AI can credibly close the gap. Output is a prioritised opportunity portfolio with an investment-grade business case.

Phase 02 Design

Target Operating Model & Solution Design

Business process blueprint, decision rights, data architecture, and model specification — authored to be adopted by the functions that will run them. Every design artefact is traceable to a line on the P&L.

Phase 03 Deliver

Build, Integrate & Validate

Delivery as operators, not onlookers: on your data, in your environment, alongside your team. Parallel-run validation against the current state, acceptance criteria agreed in writing, and go-live readiness reviews with executive sign-off.

Phase 04 Operate

Adoption, Measurement & Benefits Realisation

Change management, training, KPI instrumentation, and quarterly benefits tracking against the original business case. We hold ourselves accountable to the numbers we committed to at diagnostic.

Practice 01 AI Strategy

Enterprise AI Strategy & Value Map

Board-level framing of the retail AI investment thesis. A four-stage maturity model, a prioritised portfolio, and a phased capital plan that sequences efficiency wins to self-fund the revenue-generating programmes that follow.

Practice 02 Supply Chain

Allocation & Distribution Strategy

Demand-weighted allocation models replacing heuristic distribution rules. Store cluster architecture, constraint-aware assignment logic, and governance instrumented into the weekly allocator's routine.

Practice 03 Revenue Assurance

Sales Audit & Revenue Integrity

A transition from rule-based sales audit to ML-driven transaction intelligence. Anomaly detection, exception queues aligned to audit resources, and a measurable reduction in both leakage and false positives.

Practice 04 Customer Strategy

Customer Intelligence & Loyalty Economics

Moving the loyalty programme from cost centre to growth engine. Behavioural segmentation, customer-lifetime-value modelling, and an attribution framework finance will defend in the boardroom.

Practice 05 Store Operations

Store Operations Intelligence

Traffic forecasting, task sequencing, and labour deployment. Service-level targets held or improved at a lower labour cost, with governance that prevents drift in weeks two through fifty-two.

Practice 06 Merchandising

Assortment Architecture & Range Discipline

An assortment model that balances depth, breadth, and seasonality against working-capital constraints. Size-curve logic, cluster-based range selection, and merchant tooling aligned to the buying calendar.

Practice 07 Forecasting

Demand Forecasting & Planning

Multi-horizon forecasts engineered to the decisions they inform — short-horizon for replenishment, medium for allocation, long for buying. Explicit treatment of seasonality, promotional lift, and new-product uncertainty.

Practice 08 Analytics

Analytics Target Operating Model

The analytical function re-architected as an enterprise capability: reporting taxonomy, self-serve governance, and the migration path off the stranded spreadsheets that consume cycle time without creating insight.

Practice 09 Data Science

Data Science Capability Build-Out

Stand-up or maturation of the data science function — operating model, tooling, MLOps, and a use-case pipeline triaged on business value rather than model novelty. Run by people who have built both the team and the product.

Practice 10 Replenishment

Replenishment & Service-Level Engineering

Reorder logic that accounts for lead-time variance, lot-size economics, and supplier reliability. Service-level targets calibrated at SKU-location granularity, not averaged into meaninglessness.

Practice 11 Operations

Traffic Forecasting & Labour Productivity

Traffic models translated into staffing schedules. Weighted historicals, seasonal correction, and a closed loop from forecast to roster to actual — removing the friction between planning and execution.

Practice 12 Fulfilment

Distribution & Fulfilment Automation

Dynamic work sequencing in the DC. AI orchestrators replace static pick paths, flexing with order mix and labour availability. Throughput gains measured, not assumed.

Practice 13 Lifecycle

Style Lifecycle Economics

Predictive lifecycle modelling across launch, trajectory, markdown, and clearance. Built into the merchant's working screens so the analytical output shapes the decision in the moment it is made.

Practice 14 Portfolio

Product Portfolio Segmentation

Pareto-grounded segmentation of the assortment. Inventory capital, merchant attention, and promotional spend re-concentrated on the products that disproportionately drive profit.

Practice 15 Customer

Customer Segmentation & Targeting

Recency, frequency, and monetary value — still the most durable customer framework. Delivered against your loyalty database, instrumented into campaign tooling, measured in attributable incremental revenue.

Practice 16 Pricing

Pricing Science & Governance

Elasticity modelling, competitive indexing, and margin calibration — with the governance architecture finance will trust and legal will approve. Pricing as a managed discipline, not a monthly judgement call.

Practice 17 Fit

Size Curve & Fit Optimisation

Store-level size profiling that removes markdown drag and lost sales without inflating aggregate inventory. Rolled out cluster by cluster with measurable before-and-after economics.

Practice 18 Markdown

Markdown Strategy & Execution

Timing, depth, and cadence optimised for aggregate margin — not just sell-through. Delivered as a working merchant tool with the control logic a CFO can audit.

Practice 19 Margin

Gross Margin Diagnostic

A forensic decomposition of margin — by mix, price, COGS, channel, and geography — isolating the drivers that actually move the headline number and the interventions that reliably close the gap.

Practice 20 Working Capital

Working Capital & Inventory Productivity

Turn velocity, cash-conversion cycle, and the explicit service-level / capital-efficiency trade-off — quantified on your own data, then operationalised in the planning routine.

Practice 21 Omnichannel

Omnichannel Data Integration

Shopify, Magento, and native eCommerce data consolidated into a single analytical surface. Unified inventory visibility, omnichannel attribution, and a coherent customer record across digital and physical.

Practice 22 Platform Strategy

Platform Economics & Build-Versus-Buy

A structured, financial-grade evaluation of the enterprise platform portfolio. Total-cost-of-ownership modelling, architectural risk assessment, and a build-versus-buy framework written to withstand boardroom scrutiny.

Practice 23 Loss Prevention

Loss Prevention & Shrink Analytics

Predictive detection of theft, fraud, and operational leakage at the margin's weakest points. Analytical output wired directly into the loss-prevention investigator's workflow.

Practice 24 Data Platform

Enterprise Data Platform Deployment

On-premise, cloud, or hybrid deployment of the Cybex AI Data Hub. SQL Server 2025 foundations, AI services above, and a data-governance posture that will not embarrass the audit committee.

Outcome Margin

250–450 bps gross margin improvement

Realised from integrated pricing, markdown, and assortment programmes delivered over 12–18 months. Baseline and attribution methodology agreed with client finance before work commences.

Outcome Working Capital

15–25% inventory reduction at constant service levels

Delivered through allocation, replenishment, and size-curve programmes working in concert. Cash released reinvested per client capital policy — or returned to shareholders.

Outcome Revenue

3–8% incremental comparable sales

From CRM, assortment, and pricing interventions with holdout-group measurement. Reported against a pre-agreed baseline and independently auditable.

Outcome Operating Cost

8–15% reduction in controllable operating cost

Store labour, DC throughput, and sales-audit cycle time compressed with service-level targets held or improved. Validated quarterly against the original business case.

Practice Leadership

President, Cybex — Retail AI & Analytics Advisory

Lazar practices at the intersection of financial strategy and enterprise systems — a combination shaped by two years at Deloitte, one year at the top of the audit group at PricewaterhouseCoopers, and subsequent technology leadership at IBM. He is a Chartered Professional Accountant and a Microsoft Certified Systems Engineer — a credential set that bridges the CFO's balance sheet and the CIO's architecture with equal fluency.

He has spent the intervening two decades building retail AI and analytics systems for North American speciality retailers: allocation, merchandising, sales-audit, CRM, and the data platforms beneath them. Clients retain him when the economics of a strategic investment are material to the enterprise and the execution risk is not acceptable to delegate.

His published work includes The Cybex Quarterly, Volume 1 — twenty-four essays across AI strategy, merchandising, pricing, operations, and platform architecture, constituting the intellectual foundation of the Cybex advisory practice.
