What is the significance of Performance Engineering within an enterprise?


As companies increasingly embrace the digital platform to peddle their wares, the choices before customers increase by the day. In this context, online visibility of a company becomes important, as it a virtual window for customers to access products or services that are offered by the company.

No matter how user friendly the digital interface of a company may appear, any performance related issue with the website or application can bring unforeseen implications for the company ranging from loss of sales to loss of credibility and brand image.

To address such dire eventuality, Performance Engineering should be made part of the design and architecture of the digital interface. Performance testing (a part of Performance Engineering) can check and validate the performance and responsiveness of the application or website against the ‘load’ of increased user traffic.

Companies on digital platforms face a range of challenges that can get them vulnerable to risks or get them out of business at worst. One of the challenges can be a sudden spike in the volume of customer traffic, which can put tremendous pressure on the system. This sudden spike in workload on the system can either make it run agonisingly slow or result in downtime.

Such unexpected behaviour by the system can put off customers, resulting in reduced or no sales, and deter them from visiting the site or using the application in future. This can have a toxic impact on company’s brand image and credibility.

Performance Testing can go a long way in addressing such an eventuality. In this process, Performance Testing Experts test the system or parts of it to check whether all parameters function when the system is exposed to a sudden workload. The test also checks and validates if the system can be made scalable, should the need arise.

Importantly, instead of using Application Performance Testing as a stopgap measure to be applied once in a while in the entire end-to-end Software Development Life Cycle (SDLC,) it should be integrated as an important activity during the design and development phase a la the Agile model.

The integration can be a part of the Performance Engineering setup wherein the system (inclusive of technology, human resource and processes) is prepared to effectively respond to problems of latency and low throughput, besides meeting SLA’s before its actual deployment.

How to go about implementing Performance Engineering?

  • Conceptualization: Here, non-functional performance risks and high impact processes from a business point of view are identified. This is followed by selecting remedial activities, earmarking roles for individuals and setting up of deliverables.
