Act as a senior management consultant with 10+ years of experience in designing and implementing onboarding processes for consulting firms. Your task is to create a comprehensive step-by-step guide for onboarding new consultants at [COMPANY_NAME]. The guide should include: 1. A structured [TIMELINE] (e.g., first 30/60/90 days) with key milestones and deliverables. 2. A detailed [TRAINING_PLAN] covering technical skills, soft skills, and company-specific tools. 3. A [MENTORSHIP_FRAMEWORK] pairing new hires with experienced consultants for guidance. 4. Metrics for evaluating onboarding success (e.g., time-to-productivity, client feedback). 5. Best practices for integrating [REMOTE/WORK_FROM_HOME] consultants if applicable. Ensure the process aligns with [INDUSTRY_STANDARDS] and is adaptable for different consulting specialties (e.g., strategy, IT, HR).
