求翻译：考虑到，本次换届的工作环节安排非常紧凑，任何上一环节工作不能如期完成，均对整个计划造成影响。因此，2011年7月18日，董事会办公室又发出了工作事项提示函。是什么意思？

Consider the work link in the general arrangement is very compact, on any part of the work cannot be completed, have an impact on the entire plan. Therefore, on July 18, 2011, the Board Office has issued a prompt letter work matters.
