I only have limited experience at one company, and that was 10+ years ago. In that time frame, the assembly/disassembly procedures were being generated as the hardware was prototyped. Many government contracts required pretty thorough estimates of the time, cost and manpower needed to maintain various LRUs prior to the aircraft flying. (they seemed paranoid about surprises for some reasons)<br /><br />We had a software program (and boy oh boy was it clunky!) that organized the procedures with manpower, part, and tooling requirements.<br /><br />Distributed integrated logistics support analysis (DILSA).<br /><br />At the time I left, we had just received a color upgrade to the software. It allowed any of 8 colors of type on any of 8 colors of backgound. Red type on green background was my favorite as it was <i><b>totally</b></i> illegible.<br /><br />I assume since then, the entire support documentation effort is even more thoroughly integrated with design, and perhaps the software has been upgraded a few more times.<br /><br />By the way, I found the folks at Boeing Military in Wichita, Kansas to be total rectums.<br /><br /><br />{in fairness, though, I admit to having a personality profile totally incompatible with the military mindset, thank God}<br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>
