Internal communications platforms: A 5-layer model that works

A year ago we sketched out a four‑layer model of digital internal comms – Collaborate, Publish, Distribute, Discuss – to show that no matter how many new tools we try, communication needs stay the same. 

That post resonated well, but reader feedback and real projects showed one big thing was missing: planning. We realised every organisation also needs a top‑level Plan (or orchestration) layer to tie everything together. 

In short, five layers give a clearer picture of our comms ecosystem than four.

The new Plan (Orchestration) layer is all about consistency and strategy. It covers the scheduling, workflows and governance processes that stop teams from working in silos or chaos. Without it, comms can become ad‑hoc and reactive (think conflicting announcements or no owner for important news). 

In practice, Plan means deciding in advance who will say what, when, and how it gets published and pushed. 

Underpinning this are the ‘missing pieces’ we identified in our first model – things like service integration, analytics, governance and unified search. These ensure content flows across platforms without duplication, is tracked (who’s seen what), governed (clear ownership) and findable. 

In other words, Plan and these foundations keep the layers aligned.

The five layers explained

1. Plan (Orchestration)

The invisible top layer of strategy. It sets the calendar, scopes campaigns and manages workflows so communication is consistent and proactive. Without planning, teams compete for attention and important messages slip through the cracks.

2. Collaborate

Spaces where people actually make content. These are the collaborative work platforms (Microsoft 365 and Teams, Slack, Google Workspace, Miro and so on) where documents are co‑written, projects coordinated and ideas hatched. Collaborate is where the raw drafts and team discussions live.

3. Publish

The trusted source of truth. This is the intranet, knowledge base or employee app that holds final content: policies, company news and reference material. It must be clear, governed and searchable – the single source everyone can rely on. If Publish fails, the whole comms ecosystem wobbles.

4. Distribute

Getting the right content to the right people. Once something’s published, Distribute pushes it out via email newsletters, push alerts, targeted intranet feeds, digital signage and so on. This layer shapes how and when people see each message.

5. Discuss

The conversational layer for feedback and sense‑making. Think enterprise social (Viva Engage or Yammer), Slack channels, comments and Q&A sessions. This is where employees ask questions, voice concerns and help each other interpret information. Done well, Discuss closes the loop and builds trust; done poorly, it’s just noise.

What this looks like in practice

These five layers aren’t theoretical – every organisation builds a stack of tools to cover them. In fact, most companies mix and match platforms to stitch these layers together. For example, a classic stack might use Microsoft 365 for Collaborate, SharePoint for Publish, email or push alerts for Distribute, and Viva Engage for Discuss. An employee experience platform like Flip or Workvivo can combine Publish and Distribute for deskless teams. Or a startup stack could be Google Workspace (Collaborate and Publish), Slack (Discuss) and email alerts (Distribute). The key is that each layer is covered, and the tools play nicely together. That’s why integration (the Plan layer’s job) is so important – your newsletter needs to automatically surface new intranet posts, or your KPI data should flow into every dashboard so leadership can see the full impact.

Using the model to diagnose what’s not working

Crucially, the five‑layer model helps us diagnose where things break down. In our recent post Intranet audit vs discovery: why internal comms teams keep building the wrong thing, we argued that teams should start by understanding people’s needs before building tools. Discovery (asking “what do people need to do?”) informs everything in this model – which channels to prioritise, which content to create and how to measure success. Once you know the ‘why’, this five‑layer model becomes the ‘how’ for solving it.

We’ll be diving deeper into each layer in the coming weeks (and, of course, in our book). For example, we’ll show how small, agile discovery techniques can be used even with no budget  (such as rapid surveys or shadowing), and how the insights from that feed the Plan layer. In Chapter 2 of Digital Communications at Work we lay out this architecture in detail, and later chapters focus on building each layer effectively.

Digital Communications at Work is our practical guide for putting this model into action. It dives deep into discovery (building trust by listening), strategy (aligning channels to business goals) and the five‑layer ecosystem that drives effective internal comms. 

Our goal is to give you a strategic, joined‑up framework that connects technology to culture and outcomes. In other words, it’s about better channels for better organisations.
