HSPACE="0" VSPACE="0"></div> <bR> <div> If technology can not guarantee that defects will not be created, then defects should be found quickly before the cost-to-fix becomes expensive.  For purposes of this model, a defect has been discovered when the defect has been formally brought to the attention of the developers, <I><B>and</B></I><I><B> </B></I>the developers acknowledge that the defect is valid.  A defect has not necessarily been discovered when the user simply finds a problem with the software.  The user must also report the defect and the developers must acknowledge that the defect is valid.  Levinson and Turner provide an example where users reported problems for years before the developers of the software admitted there was a defect <A HREF="references_lev93.htm" TARGET="_top" TITLE="References"><U>[</U></A><A HREF="references_lev93.htm" TARGET="_top" TITLE="References"><U>LEV93</U></A><A HREF="references_lev93.htm" TARGET="_top" TITLE="References"><U>]</U></A>.  Since it is important to minimize the time between defect origination and defect discovery, strategies need to be implemented that uncover the defect, and facilitate the reporting and acknowledge of the defect.</div> <bR> <div> To make it easier to recognize defects, organizations should predefine defects by category.  This is a one-time event, or an event that could be performed annually.  It would involve the knowledgeable, respected individuals from all major areas of the IS organization.  The group should be run by a facilitator.  The objective is to identify the errors/problems that occur most frequently in the IS organization and then get agreement that they are, in fact, defects.  A name should be attached to each category of defect.  The objective of this activity is to minimize conflicts over the validity of defects.  For example, developers may not want to acknowledge that a missing requirement is a defect, but if it has been previously defined as a defect category then that conflict can be avoided. </div> <bR> <div> The steps involved in defect discovery are as follows:</div> <bR> <DIV ALIGN="LEFT"></DIV> <div> <B>Defect Discovery</B><B> Process</B></div> <div> <IMG
