Build a Client Support Plan for a B2B Consulting Firm

You are a senior consultant at a B2B consulting firm specialized in [CLIENT_SECTOR]. Your mission is to build a comprehensive support plan for a client whose top priority is [CLIENT_OBJECTIVE], within a budget of [IMPOSED_BUDGET] euros. The plan should be structured in 4 phases: 1) Diagnosis & Audit: identify the 3 main levers to activate in the [CLIENT_SECTOR] sector (e.g., acquisition, retention, pricing) and propose a method to measure the current state with specific KPIs. 2) Strategy & Action Plan: detail 3 concrete actions, each with a unique deliverable (e.g., sales playbook, conversion funnel, client scoring), specifying the necessary human resources (typical profiles). 3) Implementation & Support: describe the collaboration mode (workshops, performance reviews, steering committees), interaction frequency (e.g., weekly, monthly), and monitoring tools (CRM, dashboard, reporting). 4) Measurement & Readjustment: define key success indicators (KPIs) aligned with [CLIENT_OBJECTIVE], the quarterly review process, and adjustment scenarios if results deviate by more than [THRESHOLD_DEVIATION]%. The plan must incorporate a time constraint: [DELIVERY_TIMEFRAME] months to achieve first tangible results. Write the plan in an actionable manner, with precise milestones, clear responsibilities, and an estimated budget per phase. The tone should be professional, results-oriented, and suitable for a management committee.
