In the ever changing world of IT, managing and upgrading Interactive Voice Response (IVR) systems that lack proper documentation can be a challenge. IVR systems, which often serve as the backbone of many call centres, present unique problems, especially when there is no accurate map of the IVR tree or the native tooling doesn’t support this.
Understanding the Legacy Codebase
One of the most immediate challenges is understanding the legacy codebase of the IVR system. Over the years, these systems might have been patched and modified multiple times, often by different engineers with varying coding styles. Without comprehensive documentation, deciphering the logic and flow of the IVR tree becomes a complex and time-consuming task. This lack of clarity can lead to prolonged troubleshooting periods and increases the risk of introducing errors during updates or modifications.
Mapping the IVR Tree
An IVR tree is essentially the flowchart that defines how calls are routed within the system based on user inputs. When the accurate map of the IVR tree is missing, a team must manually reconstruct it. This involves tracing through potentially thousands of lines of code and listening to call recordings to understand the user journey. This process is not only tedious but also prone to mistakes, leading to potential disruptions in service.
Identifying and Fixing Issues
Without proper documentation, identifying and fixing issues can become a needle-in-a-haystack scenario. Bugs or inefficiencies in the IVR system might be hidden deep within the code, and without a clear map and continuous test performance data, pinpointing the exact location of the problem can be time consuming. This often results in extended downtime and frustrated customers, which can significantly impact the reputation and operational efficiency of the call centre.
Integrating New Technologies
Integrating new technologies or features into an old IVR system is another significant challenge. Modern IVR systems can offer a range of advanced features, such as natural language processing (NLP) and voice recognition, which can greatly enhance customer experience. However, integrating these features into an existing system without a clear understanding of its current configuration is fraught with difficulties. Compatibility issues may arise, and without proper documentation, ensuring a seamless integration becomes a monumental task.
Training and Knowledge Transfer
Teams, especially those new to the organisation, often lack documentation which makes training and knowledge transfer difficult. New team members must spend time getting up to speed with the system, often relying on trial and error or the limited knowledge of more experienced colleagues. This inefficiency can lead to increased training costs and a slower onboarding process.
Risk of System Failures
Perhaps the most critical challenge is the increased risk of system failures. An undocumented IVR system is like a ticking time bomb; any change, no matter how minor, carries the risk of causing unforeseen issues. These failures can lead to significant downtime, loss of customer trust, and financial repercussions. Proactively managing and mitigating these risks becomes much harder without a solid understanding of the system's architecture and flow.
Mitigation
While the challenges can be significant, there are strategies to mitigate these issues:
Reverse Engineering: Dedicate time to reverse engineer the existing system and create a comprehensive map of the IVR tree. This should include all possible user paths and decision points.
Incremental Documentation: As you make changes or updates, document updates will keep a known trusted metadata schema. Over time, this will build a more complete picture of the system.
Knowledge Sharing: Foster a culture of knowledge sharing within the team. Regularly conduct meetings to discuss findings, issues, and solutions related to the IVR system. This is easier when you have accurate documentation.
There is a better way.
TotalPath, our automated mapping and test harness platform can give you confidence that your IVR is accurate and can pinpoint performance, data structure and flow problems quickly and effectively. We offer an automated solution for “one click” generation of maps (including machine consumable metadata), exhaustive journey testing and various performance data metrics to make for smooth operations, migrations and knowledge transfer.
