“Silicon Reef’s work with Warner Bros. Discovery shows what’s possible when Microsoft Power Platform is deployed thoughtfully at enterprise scale. By pairing strong governance with a people‑centered approach, this Center of Excellence has accelerated adoption, empowered thousands of makers, and delivered measurable business value. This is exactly how sustainable innovation happens, through platforms that are well governed, inclusive by design, and brought to life by partners like Silicon Reef who truly understand the media and entertainment industry and their customers.”

Warner Bros. Discovery (WBD) began by defining what “good” should look like across their internal platforms. Particularly around leadership resources and SharePoint standards.

This early phase established shared goals across People & Culture, Learning teams and IT, creating a unified direction for the improvements that followed.

Attention turned to the leadership development site used by thousands of people managers. The focus was on clarity, structure and ease of use — modernising layouts, simplifying how information is accessed and ensuring the site better reflected the quality of the learning materials it houses.

Beacon templates helped create a more consistent and recognisable design, setting a new benchmark for internal sites.

As the foundations strengthened, Silicon Reef worked closely with WBD’s L&D and People & Culture teams to improve wider HR and development hubs. This included refining content structure, modernising site experiences and ensuring employees had consistent, dependable access to career development and people management resources across regions.

This work established design and content standards that continue to support WBD’s long term digital workplace strategy.

WBD explored how to bring Microsoft 365 guidance, updates and support into one place. A vision for a Viva Connections–powered Collaboration Hub was introduced.

The Hub serves as a single, trusted destination for Microsoft 365 learning, product updates, case studies and tool support. Helping employees choose the right tool for the task and smoothing transitions from legacy platforms into approved WBD applications. Integrated content from systems such as ServiceNow ensures employees can easily find help, log tickets and access updated guidance.

This Hub is designed to simplify the technology landscape and create a unified experience for all regions and business groups.

Work expanded to support the ‘MyCareer’ WBD site and wider Human Resources and Learning & Development resources.

This included helping internal teams shape content, improve site structure and plan future enhancements. Ensuring employees could access dependable career and development guidance in one place.

With more than 30,000 Power Platform licences in place, WBD began shaping a more guided approach to how apps are built and maintained. This created an opportunity to support innovation while ensuring teams had clear guardrails, helping them use the platform confidently and safely.

A formal kick‑off brought together technical leads, app makers and governance stakeholders to define how the Power Platform Centre of Excellence would guide and support WBD’s growing maker community.

Workshops introduced simple, practical practices for oversight, measurement and onboarding — giving teams a clear path for building solutions that fit the organisation’s standards, use data responsibly and align with wider business goals.

This work is detailed further in the full Power Platform case study.

The CoE began to take shape across regions, with environment strategy, DLP controls and connector policies introduced to support responsible app development.

A Champions community was launched. Giving makers a space to share ideas, learn from each other and surface early successes. This strengthened confidence and built momentum around the platform.

To bring visibility to the year’s work, WBD created a series of internal summaries and stories that highlighted key milestones across the SharePoint improvements and the Power Platform Centre of Excellence. These updates helped teams understand what had been achieved so far and reinforced the organisation’s direction as it moved into the next phase of employee innovation.

WBD begins shaping a Copilot CoE: clear use‑case patterns, data access boundaries, responsible‑AI guardrails, measurement and change plans. Maker guidance and “how‑to” content are readied for the Collaboration Hub so people can adopt Copilot in the flow of work.

Joining the Dots

The Power Platform CoE and Copilot CoE coordinate on shared standards (security, data, lifecycle), with site templates and guidance refreshed as Microsoft 365 evolves — keeping the experience simple, consistent and sustainable for teams across the organisation.
