Symptom: Project requirements change during the course of the project, adding to time and cost.
Things change. When they do, the scope or direction of a project may have to change. Accommodating such changes is necessary and expected.
But when things change, the cost and time of the project must be revised.
If projects are not based on clear agreements (contracts) that specify the deliverables (requirements) and costs, the organization may neglect the critical step of renegotiating the deal. Contracts avoid "scope creep" where resources are consumed without the necessary agreement to a higher price.
