Whilst it is considered a good practice to focus Requirements Engineering on current stakeholder needs, the high costs implied by requirements changes and the emergence of the Autonomic Computing paradigm raised the need for dealing with issues that are not currently requirements but that may come to be in the future. This work shows how foresight techniques can be used for requirements elicitation,...
As the existence of objective and subjective factors in developing software, changes in requirements is inevitable, often lead to changes in program modules also. Because of correlation among program modules, to modify a module may lead errors to related modules. Put forward to establish association diagrams of modules, and use methods of traversal of graphs, to fast track, positioning error or affected...
The rework cost of a requirement change is high. Requirements changes, which relate to hidden catastrophic failures, can cost many thousands of dollars to fix. An exploratory study on software maintenance records demonstrates that specific change characteristics in corrective change and functional change are shown to have an effect on rework. In pursuing a deep understanding of the effects, we found...
Requests for changes to software systems have a potential damaging effect on software projects and the life span of software. Changes can not be avoided since it seems impossible to produce complete, correct and stable requirements. Late requests for deep, structural software changes are particularly harmful. We present an approach for early detection of evolutionary changes of software requirements,...
