  1. SEJARAH SPIRAL MODEL Proses model yang lain, yang cukuppopuleradalah Spiral Model. Model inijugacukupbaruditemukan, yaitupadasekitartahun 1988 oleh Barry Boehm padaartikelA Spiral Model of Software Development and Enhancement. Spiral model adalahsalahsatubentukevolusi yang menggunakanmetodeiterasi natural yang dimilikioleh model prototyping dandigabungkandenganaspeksistimatis yang dikembangkandengan model waterfall. Tahapdesainumumnyadigunakanpada model Waterfall, sedangkantahap prototyping adalahsuatu model dimana software dibuat prototype (incomplete model), “blue-print”-nya, ataucontohnyadanditunjukkanke user / customer untukmendapatkanfeedback-nya

  2. FEED BACK SPIRAL MODEL Jika prototype-nyasudahsesuaidengankeinginan user / customer, makaproses SE dilanjutkandenganmembuatproduksesungguhnyadenganmenambahdanmemperbaikikekurangan Model inijugamengkombinasikan top-down design dengan bottom-up design, dimana top-down design menetapkansistem global terlebihdahulu, baruditeruskandengan detail sistemnya, sedangkan bottom-up design berlakusebaliknya. Top-down design biasanyadiaplikasikanpada model waterfall dengan sequential-nya, sedangkan bottom-up design biasanyadiaplikasikanpada model prototyping dengan feedback yang diperoleh.
