The developer is in the best position to know or ascertain the source of material incorporated into the Web site. The client may wish to restrict the developer from creating competitors sites with a similar look and feel. The look and feel at issue should be described in the contract and can include, among other things, particular graphics styles, themes, organization, and layout. Schedules for completion and delivery of various components and payments should be established. Deciding what constitutes a tasteful graphic is a subjective process.
Effective bandwidth is notoriously difficult to measure.
One approach for purposes of contracting is to specify a minimum response time for user requests, based on a specified number of users contacting the site simultaneously. To promote their business, developers will often seek a credit line and hypertext link back to their business site. Whether to allow such credits and, if so, where and with what level of prominence is a judgment call that should be specified in the contract. Especially in developing intranets and extranets, the developer may be given access to confidential information. The contract should define what information the parties consider confidential and should require that the site designer use reasonable measures to prevent disclosure of such information.
