flexibility of method construction approaches

it found while process models prescriptive, in actual practice departures prescription can occur. thus, frameworks adopting methods evolved systems development methods match specific organizational situations , thereby improve usefulness. development of such frameworks called situational method engineering.

method construction approaches can organized in flexibility spectrum ranging low high .

lying @ low end of spectrum rigid methods, whereas @ high end there modular method construction. rigid methods pre-defined , leave little scope adapting them situation @ hand. on other hand, modular methods can modified , augmented fit given situation. selecting rigid methods allows each project choose method panel of rigid, pre-defined methods, whereas selecting path within method consists of choosing appropriate path situation @ hand. finally, selecting , tuning method allows each project select methods different approaches , tune them project s needs.
