IT Operations Automation
BT Group wanted to modernize product development by reducing tedious, repetitive, and time-consuming coding work for software engineers while keeping transparency, accountability, intellectual property compliance, and data privacy under responsible controls.
Reported impact
BT Group improved software engineering productivity, reduced repetitive coding effort, and enabled faster delivery while introducing responsible AI guardrails and controls around training-data transparency, intellectual property, and privacy.
BT Group’s Digital Unit deployed Amazon CodeWhisperer from AWS as a generative AI coding companion embedded in the integrated development environments used by its software engineers. In this implementation, engineers provide the working context through natural-language comments and existing code, and Amazon CodeWhisperer generates real-time suggestions ranging from short snippets to full functions across multiple programming languages. BT also uses the service’s security capabilities to flag hard-to-detect vulnerabilities and propose remediation code inside the development workflow. The rollout was governed by BT Group’s responsible tech guardrails for transparency, accountability, intellectual property compliance, and data privacy, and was supported by onboarding sessions plus a Digital Campus learning pathway. The source does not describe a separate storage tier; the service is delivered directly into developer tooling for engineers to accept or reject suggestions during coding.
Engineers write natural-language comments and existing code in their IDEs, and Amazon CodeWhisperer uses that context to generate real-time code suggestions, from snippets to full functions, back into the IDE. The same workflow can flag hard-to-detect vulnerabilities and suggest remediations, after which engineers accept or reject the generated output in their normal development process.
“Adopting BT Group’s responsible tech principles, a comprehensive set of guardrails have been put in place for the business’ software engineering community to ensure transparency, accountability, intellectual property compliance and data privacy are prioritised with Amazon CodeWhisperer in place.”
“BT Group’s Digital Unit today announces it has deployed generative artificial intelligence (AI) coding companion Amazon CodeWhisperer by Amazon Web Services (AWS), to provide coding assistance to its software engineers.”
“BT Group’s decision to implement Amazon CodeWhisperer has also been driven by the controls and openness it provides regarding training data, helping to manage risks around intellectual property claims.”
“Over 100,000 lines of code have been generated by Amazon CodeWhisperer in its first four months at BT Group—automating around 12% of the tedious, repetitive, and time-consuming work done by an initial group of volunteers.”
“The solution is already providing 15-20 suggestions of code per active user per day for BT Group, with an acceptance rate of 37% by its software engineers who are using the platform.”
“Using Amazon CodeWhisperer, BT Group is improving productivity by providing its software engineers with a sophisticated coding assistant, by automating time consuming and often repetitive tasks.”
