Problem Statement

Organizations face persistent challenges due to fragmented communication, repeated queries, and siloed knowledge across platforms like Teams and Slack.

  • Repetitive employee queries
  • Scattered internal knowledge across platforms (e.g., SharePoint, Slack, Confluence)
  • Manual workflows like approvals, ticketing, and FAQs
  • Delayed support resolution and productivity loss
Project Objectives
  • Instant Query Resolution: Enable 24/7 conversational support using a natural language interface.
  • Automated Workflows: Handle approvals, meeting scheduling, FAQs, and ticket triage automatically.
  • Knowledge Access and Referencing: Connect to internal documentation and databases for contextual responses.
  • Insight Generation: Provide analytics on query trends, gaps in knowledge, and engagement patterns.
Scope of Work
  • Discovery & Requirements Gathering: Conducted stakeholder interviews and workshops to map critical workflows, user roles, and integration needs.
  • Design & Conversational Flow Modeling: Built robust fallback mechanisms, escalation paths, and adaptive dialogue structures to ensure accuracy and user trust.
  • Knowledge Integration: Connected enterprise content (e.g., Notion, Confluence, CRM) using advanced vector embeddings and retrieval-augmented generation (RAG) for context-aware responses.
  • Prototype & Feedback Loop: Deployed a functional chatbot in Teams and Slack, collected real-time user feedback, and iteratively refined performance.
Approach Followed
  • Requirement Analysis: Stakeholder workshops to identify key workflows, integrations, and user personas.
  • Bot Design: Defined fallback flows, escalation triggers, and interaction patterns.
  • Knowledge Integration: Indexed enterprise content using vector embeddings and retrieval-augmented generation (RAG).
  • Prototyping & Testing: Deployed chatbot in Slack/Teams for user feedback and iterative improvement.
  • Rollout & Training: Delivered onboarding support and helpdesk data, while using user interactions to enhance the chatbot’s knowledge over time.
