The role of the intranet in effective internal communication
In this blog post, we take a closer look at what makes internal communication so important, the challenges many organisations are struggling with today, and how a modern intranet can make a real difference.
Why is internal communication important?
The answer is simple: communication is what connects strategy with action.
Even the best strategy won't land if the information doesn't reach the right people at the right time. And vice versa: organisations that communicate well internally have a significant advantage.
Research from Gallup shows that companies with high employee engagement experience up to 21% higher profitability. Studies of companies with strong communication strategies have documented 47% higher shareholder returns over a five-year period compared with those without.
It is not a matter of chance. Informed employees who feel heard and involved perform better; that is well documented. McKinsey Global Institute estimates that fully utilising digital communication and collaboration tools can boost the productivity of knowledge workers by 20–25%.
In other words, internal communication is not 'soft' stuff. It is a strategic investment with a direct impact on the bottom line.
The challenges most organisations know all too well
Although everyone knows that good communication is important, in practice it is something most organisations struggle with. Here are the three most common challenges:
1. Information silos and a lack of knowledge sharing
When information gets stuck in departments, systems or email inboxes, blind spots emerge. Employees make decisions based on incomplete information, duplicate work arises, and important knowledge disappears when people change jobs.
In fact, 74% of employees say they miss important company information – not because it does not exist, but because it never reaches them (source: tradepressservices.com).
This problem is amplified in hybrid organisations, where the informal knowledge sharing by the coffee machine can no longer do the job on its own.
2. Too many channels, too little clarity
Email. Teams. Slack. SharePoint. Newsletters. Notifications.
Many organisations do not have too little communication – they have too much, spread across too many channels without a clear structure for what belongs where. The result is information overload, and the important stuff gets drowned out by the noise.
86% of employees and leaders believe that a lack of collaboration or poor communication is the primary cause of mistakes and failures in the workplace (source: Gallup).
3. One-way communication without feedback
Traditionally, internal communication has been top-down. Management sends messages out – but rarely hears anything back. That creates distance.
Today, employees expect to be involved, not just informed. Only 43% of employees say they can easily give feedback on important messages internally (source: HBR). That is a problem, because organisations without dialogue lose valuable insight – and employees who do not feel heard lose engagement.
How a modern intranet helps
An intranet is the organisation's digital meeting point. It can address all three challenges above – but only if it is built and used correctly.
Here is what a good intranet concretely contributes:
One place for all information
Instead of employees having to search through email piles, separate systems and physical folders, the intranet brings everything together in one central place. Policies, news, contact lists, onboarding materials, organisational charts – everything is available to everyone, regardless of when and where they work.
It significantly reduces search time and ensures everyone works from the same, up-to-date information.
Communication in both directions
A modern intranet is not a digital noticeboard. It is a platform for dialogue.
With comment functions, polls, forums and reactions, employees can respond to leadership messages, ask questions and contribute perspectives. This gives management valuable insight and employees a genuine sense of having a voice.
Studies show that 80% of employees feel more connected to their organisation, when the company uses social platforms internally (source: Vevox).
Targeted communication, for the right people
Not all information is relevant to everyone. Modern intranets make it possible to segment content based on department, role, location or seniority.
The frontline employee on the production floor does not need the same updates as the HR team at headquarters. With targeted communication, information overload is reduced, and what reaches the individual is genuinely relevant.
Culture and community, digitally too
The intranet is not only for operations and news. It can reflect the company's identity and help build a shared culture – whether employees sit in the same office or in five different countries.
Celebrate successes. Highlight good stories. Make room for the social side. When the intranet integrates human elements, it becomes a place people actually want to visit – not just because they have to.
What the research says
Scientific studies support what many communication professionals already experience in practice:
Engagement increases with the right digital tools. A study by Ewing et al. (2019) showed that internal social platforms can strengthen employee involvement and create a greater sense of meaning in the work. Employees who have a digital voice are more dedicated.
Productivity and results go hand in hand. McKinsey estimates a productivity increase of 20–25% through full use of digital communication tools. The gain arises mainly through faster knowledge sharing and less friction in day-to-day work.
Communication affects retention. Companies with effective communication strategies have significantly lower employee turnover (source: Vevox). And since recruitment and onboarding are costly, it is an investment that pays off quickly.
Research by Wuersch et al. (2024) in International Journal of Strategic Communication also points to a structured digital communication strategy as being crucial for building digital capabilities in the organisation – not just for the communications team, but for the whole company.
How to make it work in practice
An intranet is a tool. It is the culture and strategy behind it that determine whether it actually improves communication. Here are six principles we see making the biggest difference:
Leadership must lead the way. When leaders actively use the intranet – sharing updates, responding to comments and showing transparency – it sends a clear signal that the platform is important. More than 80% of employees prefer a workplace with open communication from management over one with lots of perks but low transparency (source: Axios HQ/HBR).
Keep the content relevant and up to date. Outdated content is one of the fastest ways to lose users. Appoint editors for key sections and set a regular schedule for updates.
Make it easy to use. The intranet must work on mobile, have a good search function and be intuitive to navigate – for all employees, not just the tech-savvy.
Invite dialogue. Feedback mechanisms, idea boxes, comment fields and polls turn communication into a conversation tool rather than a one-way channel.
Be clear about what belongs where. The intranet needs a clear role in your overall channel strategy. Define what is communicated where – and communicate that to employees.
Measure and adapt continuously. Use data from the platform to understand what works – and listen to user feedback. Internal communication is not something you set and forget.
The intranet as the organisation's digital home
A well-functioning intranet is more than a technical system. It is the shared space where the organisation meets digitally – a place where knowledge is shared, decisions are communicated and culture is built, whether employees are in the office, at home or out in the field.
At Colibo, we see it again and again: when the intranet is relevant, accessible and invites dialogue, something happens in the organisation. Information gets through. Questions are answered. Employees feel more closely connected to the company's mission.
That is what good internal communication can do. And the intranet is one of the most powerful tools for making it happen.
