Introduction
In the dynamic landscape of modern business, effective customer engagement stands as a paramount priority. To meet the demand for innovation, organisations are increasingly turning to chatbots to streamline customer interactions and deliver personalised experiences. This case study outlines the process of constructing and implementing a module within the Botpress framework, facilitating smooth integration, and employing Human in the Loop (HITL) intervention to ensure personalised support.
Challenges
While chatbots hold the potential for immediate responses and personalised experiences, integrating them into established communication platforms like WhatsApp presents distinctive challenges. These include issues such as the loss of chat history when transitioning from automated to human interactions, limited control over conversation management and the addition of new features.
Exploration
Addressing the above challenges necessitates adopting a modular development approach. This strategy involves incorporating well-defined modules and encapsulating capabilities to adeptly handle intricate queries, with the added provision for human intervention when necessary.
Objectives
This case study focuses on achieving the following key objectives:
Development of a WhatsApp chatbot using the Botpress framework to enhance customer engagement.
Illustration of employing a modular architecture in the chatbot's development and deployment.
Demonstration of the effectiveness of HITL intervention in resolving complex queries and mitigating misunderstandings.
WhatsApp Chatbot with Botpress - Approach
The case study adheres to the following methodology to attain its objectives:
