The planning based process is limited by the interdependence of components and communication between design teams. Thus, the construction of many highly complex systems should be pursued by strategies modeled after biological evolution, or market economies, where extensive planning is forsaken and multiple parallel design efforts compete for adoption through testing in actual use.<o:p></o:p></span></p><p class=MsoNormal>+++++<o:p></o:p></p><p class=MsoNormal>You may be interesting to think about how this approach applies to stove programmes.<o:p></o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Crispin in Ulaanbaatar doing exactly that<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
