To help ensure failure, encourage the client to avoid explaining their internal chain of command. Your time is too precious to waste identifying key decision makers on the client side. In a best-case scenario, your junior employee will take their junior employee's pointless suggestions as absolute gospel, while ignoring what their Internet coordinator, marketing director or CEO have to say. Let an uninvolved associate sales director dictate the design direction, and be sure that the CEO remains uninformed. In this way, early comps can be turned into finished projects, at an expense of hundreds of thousands of dollars, without ever having been approved.
Deadlines are the bane of Web development.
Content is always three months late and often unusable when it finally arrives. Structural changes are always demanded just prior to the launch of the completed project. Web agencies that wish to retain clients and ensure success ask key decision makers to sign off on ironclad schedules and include significant financial penalties if clients fail to keep up their end. So avoid doing that. Act like the project isn't happening at all.
