Pitfall 6: Creating a portal that meets the needs of only a few constituencies. Without taking the full range of users into account, portal owners generally concentrate on the areas they know best and pick features that address that limited constituency.
How to avoid: Include representatives from all areas during requirements gathering. A best practice for portal design is to determine the constituencies of the portal (e.g., marketing manager's view, transportation supplier's view, gold-level customer view) and the processes those roles are involved in. From there, features needed to complete the processes can be established.
