Accenture is scaling the deployment of Microsoft 365 Copilot across its global workforce of around 743,000 employees, marking one of the largest enterprise AI rollouts to date. The initiative began with a pilot involving a few hundred senior leaders and select teams, before expanding to 20,000 users and then scaling further across the organisation, allowing the company to refine data governance, access controls and adoption strategies at each stage.
The rollout is supported by a structured change management programme designed to drive adoption and usage. This includes targeted training, internal communications, peer learning and use case sharing across teams. The approach focuses on integrating Copilot into existing workflows across tools such as Outlook, Teams and Word, enabling employees to incorporate AI into routine tasks rather than relying on separate systems.
According to the company, usage data from the company indicates that 97% of employees reported completing routine tasks up to 15 times faster, while 53% reported improvements in productivity and efficiency. In one cohort of approximately 200,000 users, monthly active usage reached 89%, highlighting sustained engagement as the deployment expanded.
Within marketing and communications, Copilot is being used to draft, review and align content with existing brand guidelines, improving consistency across global teams. It is also enabling early stage creative development, allowing teams to generate concepts and structure ideas before involving specialised functions, contributing to faster collaboration and reduced duplication of work.
The deployment has also extended into customer facing functions through AI driven sales intelligence tools, such as solutions rolled out to around 25% of sales teams. Early results indicate that users are generating up to 43% more sales opportunities compared to non users, supported by faster access to contextual insights.
As per the company, a key aspect of the rollout has been embedding the technology within existing enterprise systems, allowing employees to access AI capabilities within their regular workflow environment. Combined with phased implementation and data security controls, this approach has supported adoption across more than 120 countries and multiple business functions..
Tony Leraris, Chief Information Officer, Accenture, said, “Copilot is a personal digital colleague. It changes the way our people work, the way they research, ideate, analyze and execute many daily activities. We were fine-tuning our adoption strategy and developing a blueprint for how it would be used in daily work. If Microsoft 365 Copilot weren’t delivering real value, our people simply wouldn’t be using it – our high adoption rate is what shows us that there is value.”
He further added, “You can’t take a one-size-fits-all message into adoption. We really had to demonstrate to certain people, especially leaders, how to use the tool and what the value would be specifically for them. Accenture people work on Microsoft platforms every day for a significant part of their day. What we want is the generative AI to meet the employee in the flow of their work, instead of creating separate destinations for people to go to.”
“Real value from AI investments like Copilot doesn’t come from simply turning it on. It comes from investing in your people, helping them understand how to use it, how to trust it and how it fits into the way they work.” he added.
Haley Rosowsky, Global Microsoft Ecosystem Partner Marketing Lead, said, “It fostered understanding and inspired people to go off and do their own experimentation and try new things. We showcased people who were getting value out of working in new ways with Copilot and gave them a bit of a pedestal moment that everyone could learn from.”
Jason Warnke, Global Marketing and Communications Experiences Lead, Accenture, said, “One of the things that’s massively important in a global organization like ours is consistency of message. It gives people a serious leg up on generating something in the flow of work that represents the brand. People are now confident enough to say, ‘Hey, I just asked Copilot, it gave me a great idea,’ and then speak up. I thought that would go away, but it’s sustained.”
Harry Holstrom, Vice President and U.S. Sales Lead, Avanade, said, “It’s about bringing content and context to the conversation that allows us to scale and move quickly and be much more effective in those client conversations. They come across in their emails like people with 20 years’ experience, thanks in no small part to the D3 tool and the framework we’ve set up around it.”
Gord Mawhinney, Americas President and U.S. General Manager, Avanade, said, “With D3 and with Copilot, we are able to scale even more rapidly and bring our clients valuable insights on day one.”
