Multiply the length and width of the tile to determine its area. For example, a 4-inch by 4-inch tile is 16 square inches. Divide the area of one tile -- in square inches -- into the total you just calculated to determine the number of tiles you need.
Requirements management. Requirements management is the process of documenting, analyzing, tracing, prioritizing and agreeing on requirements and then controlling change and communicating to relevant stakeholders. It is a continuous process throughout a project. A requirement is a capability to which a project outcome should conform.
A requirement management plan generally has three to four sections. The requirements management plan will begin with an Introduction. The Introduction section of the plan defines why the plan is being used and why the requirements are important to manage. The second section will give an overview of the requirement management.
