ABSTRACT
One thing that can be guaranteed for any project lasting more than a few weeks is that the end result will be changed in some way from the original concept. As experience accrues through the design and fulfilment stages it is inevitable that minor corrections and changes will be needed to correct errors or to adapt to conditions and circumstances that were not foreseen when the project was authorized. One important aspect of changes and their control is that changes made later in a project lifecycle will cost more than changes made near the project beginning. Changes made to correct errors in drawings and specifications during the initial project design phase might delay progress but should not be expensive. Even the simplest change can sometimes affect the costs and progress of a project far more than the change originator envisaged.
