Abstract
DEMO is a methodology for designing and engineering organizations which is
mostlyusedforInformationSystemDevelopment(ISD)andredesigningthebusiness
processes. DEMOhastheabilitytoreducethecomplexityofanorganizationbypro-
vidingaconceptualmodelofthatorganization[10].
AlthoughDEMOhaspromisingadvantagesandhasprovidedsuccessfuloutcome
in practice, it hasn’t received the deserved attention from The individuals in practi-
cal fields. While many of the competitor methodologies are more successful and ac-
ceptedamongthepractitioners,DEMOisattheriskofbeingforgottenamongallother

ItseemstrivialtouseeffectivetacticstoincreasetheacceptanceofDEMOamong
individuals in practice. These tactics can only be effective if they take the reasons
behind this specific point of view about DEMO into account. Various factors from a
