The H-DAM model deals effectively with some of the biggest practical problems in data management.
It allows you to break up data entry, validation and update tasks across people, including assigning responsibility to the people who create it, gather and make most use of particular information and therefore have both the greatest incentive to maintain it and the best data. (For example, the most accurate contact details for the most current clients is usually found, not in the corporate database, but hidden and inaccessible to others, in individual staff email address books. H-DAM helps open up that resource.)
When people have a small data task that is directly relevant to them, they are most likely to keep good data – and H-DAM makes it easy for them with instant on-screen access from any computer or device.
This is especially effective for directory apps.
