The condition under which a Business Partner/Avaya Tier 2 is not required to escalate to Avaya Tier 3 is when the Business Partner/Avaya Tier 2 has isolated the issue and found a resolution. This means the problem has already been identified and resolved, eliminating the need for further escalation.
Discipline 4, Determining Root Cause, of the 8D Troubleshooting Methodology is typically the responsibility of Avaya Tier 3. Tier 3 support is generally responsible for the most complex and in-depth issues, making them suited for root cause analysis.
In the 8D Troubleshooting Methodology, Discipline 3 focuses on isolating the problem and preventing it from escalating. Developing immediate controlled actions to isolate the problem ensures that the issue is contained while working on a permanent solution. Additionally, trying actions that bypass the issue, such as creating a temporary workaround, is also a part of containing interim actions to restore service temporarily. These two steps are aimed at managing and controlling the issue in the short term.
After receiving the trouble ticket, the next logical step for Avaya Tier 3 support in the ADM process is to implement a solution. This involves diagnosing the issue based on the stated problem and findings, and then taking actionable steps to resolve the issue. Installing a patch, praising individuals, or updating the Knowledge Management database are not primary actions that directly address the immediate need for problem resolution.
