"Some key questions need to be asked continually throughout a project"

Many times we ask questions early in the project concerning both business and technical issues. If an application is being updated we might ask; "Do we need to load test the application?". If the answer is no the first time can we really assume that it will be no 3 months later? Questions like these need to be asked again because things may change on the project. A change request might occur that will increase the size of a transaction. A new server may be added to balance the load. Not asking the question again may lead to a surprise the night before implementation when you find out that the network team has concerns. Keep asking those questions!
