The method, in five phases
Every mandate at Costantini & Partners follows a recognisable structure, calibrated to the principal but built on five non-negotiable phases. The sequence is not cosmetic: each phase prepares the next, and skipping one compromises those downstream.
Diagnostic
Before proposing any intervention, two-to-four weeks of silent work on the company. Reading of existing data, conversations with the principal and key people, analysis of real operating flows (not declared ones), mapping of suppliers in place, active systems, the breaking points of the current commercial model.
The output is an eight-to-twelve page diagnostic memo delivered to the principal. It does not yet contain the operating proposal. It contains what we have understood of the company, where we believe the real tensions lie, and what questions we still need to address together before deciding how to intervene.
The internal rule: no work proposal is presented before completing the diagnostic. This is the sharpest distinction between serious consulting and execution agencies.
Positioning
Only after the diagnostic, work on the voice of the company. What truly distinguishes it, whom it speaks to, in what language. Not a marketing exercise — an exercise of internal clarity on who the principal wants to be when speaking to those who do not yet know him.
The output is a positioning brief (six-to-ten pages) that becomes the reference document for every subsequent decision: channel choice, content construction, price calibration, visual identity. All downstream choices are tested against this document.
In some mandates this phase ends here — the principal wants only the repositioning, execution then handled internally or with historical suppliers. That is fine: positioning is a complete asset in itself.
Architecture
When the mandate includes execution, phase three is the construction of the operating infrastructure that allows positioning to live beyond the document. Website, tracking system, CRM, conversational automations, integrations between tools.
The non-negotiable principle: the infrastructure built belongs to the principal, not to the consultant. No proprietary platforms from which the client cannot exit. No technical dependencies that bind him to the firm beyond mandate duration. The asset built remains the principal’s.
Technology choices are made by three criteria, in this order: durability over time, sustainable operating cost, possibility of replacing the original supplier without trauma.
Execution
The fourth phase is the most externally visible and the least significant in the value structure. Acquisition campaigns, nurture sequences, content, editorial calendars, commercial conversations with the company’s clients. All the work traditional agencies present as the work.
At Costantini & Partners it is real work, executed with care. But it is never divorced from the three preceding phases: execution is worth what precedes it. A campaign built on confused positioning produces useless traffic. An email sequence on shaky infrastructure produces lost orders.
Governance
The final phase, often absent in traditional consultancies, distinguishes a durable mandate from spot execution. Construction of review routines for data, definition of internal company responsibilities (who watches what, who decides what, who reports to whom), production of synthesis dashboards that allow the principal to understand the state of the digital infrastructure in five minutes per week.
The stated objective: to make the principal progressively less dependent on the consultant. Our usefulness is not measured by the indispensability we produce but by the autonomous capacity we leave behind. The longest continuous mandates (three years and beyond) are those where the principal knows he can dismiss us at any moment, and chooses not to.
