Product writing playbook

Summary

AC Digital had no shared content standards across product squads. Teams wrote differently, copy reviews relied on opinion, and teams duplicated work. I built a Product Writing Playbook that teams actually adopted, giving squads the confidence and tools to write consistently.

My role

I created AC Digital's first Product Writing Playbook and led its adoption across 20+ autonomous product squads, working as Lead Product Designer.

This involved:

Approach

I focused on creating practical guidance that solved real problems, not documentation that would sit unused. Adoption had to come from teams seeing value, not from top-down mandates.

How I built the standards:

How I secured Legal and Compliance buy-in: I borrowed principles from Monzo's content guidance and created before/after examples showing how plain English could maintain legal meaning without formal language. This demonstrated that "formal doesn't equal professional" and gave Legal confidence that simplified copy wouldn't create compliance risk.

How I drove adoption:

The turning point: Teams adopted the playbook voluntarily once they realised it made their work easier. Uniformity meant squads could reference each other's previous work, accelerating content creation rather than slowing it down.

Deliverables

Together, these enabled squads to apply standards independently and maintain content quality without central gatekeeping.

Impact

The playbook was adopted across squads within 12 months, raising content standards across AC Digital. Copy-review cycles shortened, rework decreased, and designers gained the autonomy to justify content decisions using shared principles rather than opinion.

For customers, clearer content made journeys easier to complete. Microsoft Clarity recordings showed users moving smoothly through areas that had previously caused hesitation.

For the business, the playbook gave Legal, Compliance and Product shared standards for reviewing copy. Teams could explain their decisions using agreed principles, reducing reliance on personal preference.

The measure of success: I was able to step back from my consultancy role as the guidance became embedded and teams applied it naturally. The standards were adopted, not enforced

Real before/after examples showed stakeholders that we could reduce and simplify copy whilst improving clarity

What I learned

On adoption: Involving designers in the guidance and showing its value through real examples helped teams adopt it willingly. The playbook succeeded because teams saw it as theirs, not mine.

On stakeholder management: Showing Legal and Compliance concrete before/after examples was more effective than abstract arguments about "plain English." People need to see the solution working before they'll trust it.

The playbook’s value was in helping teams make better writing decisions independently.
