Supply Chain Consulting Engagement Process

The standard supply chain consulting engagement follows six phases regardless of firm size. The phases apply to both tactical projects (logistics tender management, inventory review) and strategic transformations.

Phase 1: Project Definition

Before any charges apply. Initial meetings to establish scope and objectives. The output is a formal consulting proposal covering:

• Terms of Reference
• Objectives (business-level and project-level)
• Execution strategy and technical/project approach
• Fixed-charge or day-rate pricing with assigned consulting days
• Scope in and scope out (explicitly stated)
• Deliverables list with acceptance criteria

Best practice: Fixed-fee engagements for defined-scope projects. Day-rate structures for open-ended advisory work. Always break down costs by work stream or phase.

See Supply Chain Consulting Scoping for the full scoping methodology.

Phase 2: Data Collection and Validation

Consultants gather and verify data through on-site work, client team collaboration, and system extracts. Data must accurately reflect actual operations — not how the client describes operations, but how they actually run.

Typical data collected:

• Order profiles: lines, units, weight/cube by customer and channel
• Inventory: SKU count, turns, ABC velocity distribution
• Throughput: volume by period (daily, weekly, seasonal)
• Cost data: labor rates, freight rates, warehouse costs
• Service data: OTIF, dock-to-stock, order cycle time
• System landscape: WMS, TMS, ERP, planning tools

Validation principle: Cross-reference three independent data sources for every key claim. If WMS data, finance data, and floor observation tell different stories, resolve the conflict before proceeding.

Phase 3: Framework Options

The consultant presents multiple potential solutions with respective strengths and weaknesses before committing to one direction. This is a structured decision point — not a reveal.

Why present multiple options:

• Avoids consultant anchoring on the first workable solution
• Gives the client visibility into the trade-off space
• Creates shared ownership of the direction chosen

Typical option structure: 2–4 scenarios ranging from conservative (low capital, incremental improvement) to transformative (high capital, step-change). Each scenario evaluated against cost, service, risk, and implementation complexity.

Phase 4: Detailed Assessment

The bulk of consulting time. In-depth analysis, modelling, and costing of the preferred option(s). Typical workstreams:

Workstream	What’s produced
Network analysis	Facility count/location optimization, flow optimization
Labor modeling	Staffing models, productivity targets, cost-per-unit
Technology assessment	System gap analysis, vendor shortlist, business case
Process design	Future-state process maps, standard work documentation
Financial modeling	NPV/IRR/payback for each scenario

Phase 5: Assessment Conclusion

A comprehensive report documenting:

• What data was collected and how it was validated
• What options were considered and how they were analyzed
• The recommended solution with supporting rationale
• Risk factors and mitigation strategies
• Expected benefits with confidence intervals

Report structure (typical): Executive summary → current state findings → options analysis → recommended future state → implementation roadmap → financial case → appendices (data, models, references).

Presentation format: For major engagements, a structured steering committee presentation precedes the written report. The steering committee session is the decision gate — the report confirms what was decided in the room.

Phase 6: Implementation

A detailed implementation plan covering:

• Tasks and task owners
• Timing and milestones
• Resourcing requirements (internal and external)
• Stakeholder engagement plan
• Risk management and contingency planning
• Change management approach

Client execution options:

1. Consultant-led implementation (highest cost, fastest)
2. Internal team with consultant advisory support (most common)
3. Interim professionals for specific functions
4. Fully internal (lowest cost, highest risk of delay)

Critical discipline: The consulting firm that did the assessment is not automatically the right choice to lead implementation. Assess separately.

Engagement Types by Scope

Type	Typical duration	Consultant count	Fee range
Tactical (logistics tender, inventory review)	4–8 weeks	1	$25k–$75k
Operational assessment	6–12 weeks	2–4	$75k–$300k
Strategic transformation	6–18 months	4–12+	$300k–$2M+
Network design study	8–16 weeks	3–6	$150k–$500k

[!gap] Fee ranges are directional only — vary significantly by firm tier, geography, and engagement complexity.

Client Responsibilities by Phase

Consultants deliver analysis; clients make decisions. Clarity on this boundary prevents scope creep and accountability gaps.

Phase	Client responsibility
Definition	Sponsor alignment; data access commitments; internal team assignment
Data collection	Timely data provision; system access; interview scheduling
Options	Decision on preferred direction (no deferring to the consultant)
Assessment	Review and challenge findings; internal validation
Conclusion	Executive acceptance and resource commitment
Implementation	Named internal owners for each workstream
