"Increased quality and reliability for PPT application gained from test automation actionable insights."

The Challenge

  • Assessment of Push To Talk application performance.

  • Audio MOS score measurement of PPT application as the existing tool did not cover this use case.

The Solution

  • An agreement that viSer test automation solution with Audio MOS was implemented.

  • Consideration was given to the KPIs that consisted of the Audio MOS POLQA score. The focus was on KPIs including, connection time, call establishment time, and mouth-to-ear latency.

  • As well as viSer, Viser Web Services (VWS) Analytics Studio was deployed as the fastest way to analyse test results and view them. A tailor-made interactive dashboard was created for the reporting of test results for only the relevant KPIs.


The Results

  • Test efficiency improvements:

Significant increases in test efficiency on average by 75% as a result of the implementation of test automation used to streamline operations​.

  • Quicker identification of issues:

During the testing phases, more issues were identified and resolved much earlier in the project than in previous ones.

  • Quality and reliability increases:

Over time, the project showed achievements in both quality and reliability. These proven increases for the PPT application confirmed that it was fit for mission critical usage.
