How to use your intranet to generate ideas?
Even the most elementary Intranet fulfils the most basic of Intranet functions – bringing users together to the one online area. However, what people see when they get there can vary widely. So if you’re struggling to find interesting things to keep your Intranet fresh, what about trying a ‘Share your Ideas’ feature. Companies like ideascale.com offer cheap but very effective software packages that you can incorporate into your Intranet that will drive take-up and help ensure your site remains interesting to your users.
