The Standish Group suggests that putting together a successful project plan requires negotiation. Every project must have a business objective such as: increasing revenue, improving customer satisfaction, reducing errors, cutting costs, or improving control. The scope, which defines the boundaries of the project, such as the business functions and organizations impacted, as well as the constraints, such as deadlines, budget ceilings, and other assumptions, must be defined in business terms. Once this is done then a plan can be presented to the executive sponsor to start the negotiations. The four elements that make up the negotiate skills are power, leverage, empathy. and information.
