This bit of arithmetic is about the preconditions for cultivating an atmosphere of corporate trust that makes for successful internal communications. Much lip service is paid to the importance of internal communications—but that talk isn’t always matched by follow-through in the areas of authenticity and in-person contact.

To be credible and useful, messaging of an internal communications strategy must be authentic. Leaders need to speak in their own voice; be transparent even when the news is difficult; and most importantly, demonstrate that the organization encourages employees to speak truth to power. This ethos of authenticity, transparency and openness is the foundation of every successful internal communications campaign—because it’s indispensable in cultivating trust.

A second vital point to remember is that wherever practical, employee communications should take place through face-to-face exchanges. They’re the most effective and trusted form of internal communication. Accordingly, design communication strategies and tactics around opportunities for meaningful face-to-face interactions. If distance is a challenge, explore the use of web conferencing to bridge distance and maintain a personal level of contact.

Granted, turning these principles into practice isn’t as simple as mere arithmetic—but it’s an equation well worth remembering as part of your internal communications toolkit.
