Articles are ideal for delving into a topic and helping colleagues gain a greater understanding of them (for example, shining the spotlight on a particular achievement or announcement).
Choose a style that fits your topic. For example, if writing a story about a successful project implementation, you could take a more personal approach by interviewing those involved to discover how they achieved it. For a story detailing a set of changes to an IT system, you may want to be more factual and to-the-point - so that your audience gets the ‘need to know’ information easily and quickly.
Of course, you can include articles in existing DSM newsletters. But there’s also nothing to stop you from sharing an article via your external social media account: for example, a blogpost on LinkedIn.
