The methodology is the layer beneath the Transformation. Every diagnostic, every plan, every recommendation an engagement produces is built on a small number of named concepts: operator-derived, math-checked, and carried through consistently across the five phases of the redevelopment.
This page introduces them at altitude. The math itself sits with the engagement. If you haven't yet, the Transformation page is the better starting point: it describes how this methodology walks a firm through the redevelopment, from current position to top-quartile. This page tells you what's under the hood.
Three layers, in sequence
L1. Operator Input Model
Two languages, one set of math. Enter your numbers in the operator-familiar P&L categories your accountant gave you; the engine reclassifies them automatically into SLI-comparable output. You see both views side-by-side, so the conversation can be had in whichever vocabulary the room speaks.
L2. Dual Accounting View
Loaded versus Unloaded. The same P&L can be read two ways depending on whether burden (employer-side payroll tax, benefits, training) is shown inside labor cost or absorbed into G&A. The dual view makes the cost of every billable hour visible, and identical net profit, under either lens, so pricing, dispatch, and utilization decisions are made against true labor cost rather than the partial picture most MSPs see by default.
L3. Prescriptive
Model forward. Adjust pricing, utilization, bucket sizes, or headcount and see the expected outcome before doing it. This is the layer that turns a benchmark report into a Monday-morning decision.
The diagnostic vocabulary
The named concepts that show up in every engagement. Each is a pointer to a specific kind of leak, leverage, or sequencing decision.
xWages (Multiple of Wages)
Service revenue per dollar of service wages. Three named variants depending on which wage population you're measuring against: delivery only, SLI's blended scope, or EO's full above-the-line scope. Each variant pairs as the exact inverse of a corresponding wage ratio (BWR, DWR, SGWR), and Best-in-Class anchors range from 2.5× to 3.2× depending on the variant. The single-number xWages most operators have been quoted hides which scope it was computed at; we name the scope explicitly.
The Wage Ratio Family
Five named ratios (BWR, SMWR, AMWR, DWR, SGWR) that decompose service-labor cost into a coherent three-tier structure. Three of the five (BWR, DWR, SGWR) pair as the exact inverse of a corresponding xWages variant. The remaining two, SMWR (Service Management) and AMWR (Account Management), are the component ratios that compose into DWR and SGWR respectively. The decomposition makes the cost of a hire visible before it lands on the P&L; the named tiers make it diagnosable after.
Real Rack Rate (RRR)
What each employee needs to generate per billable hour to cover their full economic cost: wages, burden, overhead, and pricing margin. RRR is the per-tech anchor against which every agreement, project, and hour of T&M work is measured. It replaces the partial-burden approximations the industry inherited and exposes the gap between what an agreement says it consumes and what it actually consumes.
Wage Ratio Bridge Formula
The math identity that connects EO's burdened pricing side (Real Rack Rate, EHRm) to the unburdened W-2 tracking side (the wage ratios operators see in their PSA). Lets an operator evaluate the cost of a management hire in wage-ratio terms before the offer goes out, instead of discovering it on the P&L ninety days after onboarding.
Rack Rate Performance (RRP $ and RRP %)
Every hour an employee spends on an agreement is valued at their Real Rack Rate (RRR), which is what those hours would have generated if billed hourly at full rate. The RRR-valued hours are then compared against what the agreement actually produced. The gap is the agreement's rack-rate-performance signal: independent of the firm's specific cost structure, comparable across employees and across firms. RRP comes in two paired forms: RRP $ (dollar form) for portfolio ranking and absolute analysis, RRP % (ratio form) for per-agreement leverage scoring.
Service Revenue Mix
The percentage decomposition of service revenue into recurring/managed, project services, and time-and-materials. Each stream carries its own EHRm leverage band (1.0–1.2× for T&M, 1.3–1.5× for projects, 1.0× and up for managed/ recurring). The blended-only view most operators inherit hides which stream is leaking; the per-stream view names it.
The Pressure Test
The diagnostic framework for evaluating an MSP's service department. Three phases applied uniformly: load and validate the actuals, diagnose where the math doesn't hold, and model scenarios for each lever. Every MSP walks through the same front door; only the prescriptions differ.
The EO Index
Expected Outcomes' operational-readiness diagnostic. The EO Index reads where the firm sits across four pillars: Service Operations (service delivery and account management), Sales & Marketing (the new-business engine: hunting plus marketing funnel), Instrumentation (the firm's measurement infrastructure: PSA, accounting, RMM, CRM, documentation, configured to produce data the firm can lead from), and Financials (where the firm's outcomes sit relative to the published benchmark network maintained by Service Leadership Inc.). Each of the three operational pillars is scored on a five-rung Implementation Rating scale (Established / Operating / Building / Considering / Not Yet); Financials is scored against SLI's published benchmarks directly. The composite is the equal-weighted average of the four pillar percentages. The EO Index is the instrument that tells the leadership team whether the firm is ready for the next phase of the redevelopment, where the gaps are if it's not, and whether structural risks (a low Sales & Marketing reading, for example) demand attention regardless of how strong the other pillars are reading. The EO Index drives operators toward higher OML through its four-pillar diagnostic; it is parallel to and complementary with SLI's SLIQ, not a replacement for it. (Distinct from but complementary to The Pressure Test, which is the engagement-grade methodology focused on the Service Operations pillar.)
Client Quality Index (CQI)
A composite score that ranks each client by the full economic value of the relationship, not just the profitability of their recurring agreement. CQI captures four dimensions: Agreement Productivity (AP), Project Pull-Through (PjPT), Hardware & Software Pull-Through (HSPT), and Account Management Engagement (AME). The score is size-neutral: a small client with a healthy, active relationship scores higher than a large client whose recurring agreement is profitable but who never buys projects, never refreshes hardware, and never takes a Business Review. The ranked output is what an operator wants on a Monday morning: the book of business sorted by relationship health, not by contract size or revenue.
The Honesty Gap
The distance between what the books are saying and what the operating reality actually is. Splits cleanly into three kinds of leak. Pricing leak: charging less than RRR justifies. Measurement leak: the books obscuring what's there. Structural leak: costs that arise from how the firm is organized rather than from its prices or its measurement discipline (account-management overhead absorbed silently into agreement margin; service-management coverage that scales sub-linearly with billable headcount; client portfolios with a long tail of low-CQI agreements that consume disproportionate management attention). All three are recoverable; you have to know which one you have.
Automation Capacity Gap (ACG)
The structural slack between what the firm should produce per billable hour at canonical pricing and what Best-in-Class firms actually produce in the field. ACG explains why an OML 4 MSP can run measurably below the 74% billable-utilization anchor and still hit Best-in-Class gross margin: automation has compressed the labor input per dollar of revenue, and the survey-era ratios haven't yet repriced.
Operational Maturity Level (OML)
Five stages of operational sophistication, drawn from SLI's extensively validated maturity framework. OML is the sequencer. It determines what to fix first, what to fix second, and what to leave alone until the firm has moved up. Every recommendation is OML-aware.
The framework is teachable. The math is checkable. The prescriptions are sequenced. The methodology is the layer beneath every diagnostic; the diagnostic is the deliverable.
