Redefining Quality Engineering in The Era of Cognitive Computing

Present day, organizations are continually innovating and reinventing their offerings and themselves with the sole aim to make the lives of their customers easier. Currently, at the peak of this drive to innovate lies Cognitive computing, also known as ‘Super-Intelligent Computers’. Personal Assistant Apps such as Apple’s Siri, intelligent machines like Google’s autonomous car, Amazon Go for Smart shopping and even Facebook’s face recognition feature mimics and behaves like humans.

These algorithms survive on data; the more the quantum of data you feed into them, the smarter they become and in turns, more precise the results. Cognitive computing today is bringing about a radical change in the Quality Assurance Lifecycle, and is impacting every phase; powered by automation. It is enabling organizations in better decision making, analyzing historic data and reports to predict or forecast future results.


Cognitive computing is a product of Artificial Intelligence (AI). AI is the theory and development of computer systems which are able to perform tasks that normally require human intelligence. Today, enterprises have to deal with large quantities of unstructured data across varied domains thus increasing the scope of applications of AI.


Machine Learning: A process of discovering varied patterns or similarities across data which can be used to make meaningful predictions.

Natural language processing: The ability for a system to understand or interpret ‘text’ or ‘parts of text’ much the same way humans do. This can be used to analyze customer feedback, creation of automation scripts etc.

Human interaction: Today wearable devices, loyalty programs, social networking etc. are transforming into critical sources of data, enabling systems to gauge human emotions, sentiments, purchase patterns which are proving to be vital.

Self-Troubleshooting: The ability to detect a problem or an anomaly in a system, even before it has occurred, and guide the system to take preventive and corrective measures.

Deep Learning: Defined by the use of face and voice recognition techniques leveraged at several places. For instance, Facebook uses deep learning to learn about a person’s identity, and provides suggestions for photo tagging. Another good example is Amazon leveraging AI coupled with deep learning to give their customers the ‘Just Walk out Shopping’ experience.


Cognitive algorithms, if infused into the different phases of the software life-cycle, has the ability to alter it completely and result in enormous benefits to QE from a cost, time and quality perspective. Let’s look into its use cases:

  • AI will replace the way developers build applications, and can lead to faster software development
  • The cost spent on QA, historic project data such as efforts, can feed AI based systems, resulting in better estimation of Cost of Quality across the Software Life-cycle.
  • AI can suggest better strategies, automate test design completely and increase test coverage
  • AI systems can use production data and analyze which procedures and functions are being used regularly
  • Chabot’s have become the ‘in- thing’ for interactions with consumers, and helps gauge feedback, and encourages communication within the Enterprise.


Well, the aim of AI is not to replace humans but only to augment them. For instance, in the QE&A world, when automation became easy to implement and in turn popular, it was rumored that a lot of people would lose their jobs. However, there are some tasks for which humans cannot be replaced such as designing the automation framework and associated automation scripts.

Hence, the role of testers evolved from being manual testers to automation experts. So, it is very crucial for humans to expand their skills in the direction where the industry is moving towards critical Defect Metrics. It is not always the case that AI systems work in the right direction. If not fed with the right data or tested thoroughly, they are bound to weaken as well.


A very fresh example is that of the catastrophe of Microsoft’s teen girl inspired chat-bot named ‘Tay’, which had to be removed from the site a day later due to malicious content and data sources. When it comes to the applicability of AI systems across industries, there are infinite scenarios, and each of these would require rigorous amounts of testing, coupled with use of tools and analytics. The integration of new code based AI systems with the traditional code could also face several integration issues. So, one can easily conclude that these systems can’t replace humans completely.

Hence in short, cognitive computing is very much in the need of hour, but they have to be tested very patiently with all possible scenarios. Else they can hamper the privacy of users- a troublesome issue that could have drastic consequences.
