Intranet Portals Get Streamlined

Summary:
An analysis of intranet portals found slimmer information architectures and a renewed emphasis on fresh content and useful applications. Past findings, including those on role-based personalization, were confirmed.

It's been almost three years since our last project assessing the usability of intranet portals. This is a good time to take a fresh look at portal design, since three years is also the average time between intranet redesigns.

To find out what's working now, we analyzed a new series of portal projects and compared them with the conclusions from the previous round.

Findings: Unchanged

In the larger scheme of things, three years is not much time, so it's not surprising that all of the findings from our initial portal project still hold. In fact, none of the forty-five best practices documented in the report's first edition have changed. Yes, we've gained many new insights, but what was good three years ago continues to be good today.

In particular, the new project confirmed the following findings from the previous project:

New Findings

First, portals are becoming too popular for their own good. Some companies have multiple "portals" because many software vendors include portals with their products to make them seem more important and to get a shot at being on top. This obviously doesn't work, because an enterprise portal by definition must be the one entry point to the intranet and all of its content and applications. So, you can only have one portal. Everything else must be subservient to it for the concept to work.

Second, as time passes, the amount of stale portal content grows. Portal managers have therefore started explicit efforts to combat outdated information. The Defense Finance and Accounting Service's Project CleanSweep audits pages across its portal and tells owners of outdated content that it will be removed by a certain date if it's not refreshed. Other portals use their content management system (CMS) to track expected revision or expiration dates for all pages, and authors must estimate these dates whenever they create or update content.

Third, because much portal software continues to be overly complex, portal managers have recognized a need for training in the correct use of portal features. For example, one big company found that 26% of pages contained miscategorized metadata. You can't just assume that people will understand a complex concept like metadata without instruction.

Fourth, user acceptance requires explicit attention. A big company (that prefers to remain anonymous) had its portal project fail completely. Performance was miserably slow, usability was poor, and people simply refused to use the portal--to the extent that they used the old intranet pages more than eight times as much as the new portal. The portal project had been in vain; to save the intranet, the portal was removed after less than a year.

Portal projects are more likely to have a happier outcome if they emphasize user needs from the beginning, and also employ various tricks to enhance user acceptance. For example, we've begun to see good use of multimedia and video clips on portal homepages; even something seemingly frivolous like a user poll can help make the portal more fun and appealing.

Fifth, information architecture (IA) is becoming streamlined. For example, Sprint has reduced the number of tabs on its portal from eight to five due to a corresponding reduction in the number of major categories. As we discover more about how to build a good intranet user experience, portal teams can take advantage of accumulated usability findings across companies and emphasize the most useful areas.

Portlets on the portal homepage follow a similar trend: fewer, and more useful. In the past, portal projects typically offered users portlets simply because they could -- even though organizations generally didn't provide enough content or features to justify the portlets' prominent placement. In another design simplification, offering two layers of tabs seems to be a thing of the past. Good riddance.

Finally, we're seeing a shift in how organizations use portals. Where portals were once pure information aggregators, organizations are increasingly using them as application organizers. Many companies now offer a variety of killer apps and are moving more of them into the ports. This also helps with user acceptance, because a tools-oriented approach to the portal makes it more obviously useful.

All in all, intranet portals are definitely maturing. The user interfaces are simpler, and teams are getting better at managing both the portal itself and its relationship with other departments and content providers. We definitely see a continuing need for better ROI measures. Nonetheless, many portal projects achieve significant improvements -- which are almost as easy to gauge as the spectacular failures.
