Rapid Application Development in Telecommunications with Time Boxing

Rad razmatra postupke programskog inženjerstva koji omogućuju brzi razvoj programske opreme, uz različite uvjete koje određuju potpunost zahtjeva, veličina i funkcionalnost programskog proizvoda, vrsta posla i sastav razvojnog tima. S obzirom na navedene kriterije usporedbe, prvo se razmatraju prednosti i nedostaci najpoznatijih razvojnih modela, te uloga inženjerstva programskih zahtjeva u skraćenju vremena razvoja programske opreme. Tržište i korisnici programske opreme utječu na kvalitetu i cijenu programske opreme, sposobnost razvojnog tima i vrijeme do isporuke programskog proizvoda i time nameću primjenu metoda brzog razvoja uz znatna vremenska ograničenja. Za vođenje malih projekata i projekata srednje veličine, predložen je Fast Track model kojim se vrijeme razvoja programske opreme skraćuje izvođenjem paralelnih aktivnosti i inkrementalnom isporukom programske opreme. Brzi razvoj programske opreme, u slučajevima nepotpuno specificiranih zahtjeva, omogućen je primjenom Dinamičkog postupka razvoja sustava. Ovaj model skraćuje vrijeme do isporuke gotove programske opreme iterativnim aktivnostima i inkrementalnom isporukom programskog proizvoda. Za razliku od velike većine standarnih modela, uključivanje korisnika u cjelokupni razvojni proces jedan je od osnovnih principa Dinamičkog postupka razvoja sustava. Praktička verifikacija karakteristika vodopadnog modela, Fast Track modela i Dinamičkog postupka razvoja sustava, provedena je primjenom generaliziranih stohastičkih Petrijevih mreža. Simuliranje modela provedeno je primjenom DNAnet alata.This thesis considers software engineering techniques which enable rapid application development with several conditions defining requirements, software size and functionality, work type and development team structure. According to comparison criteria listed above, there are discussed advantages and disadvantages of most known development models, and also role of requirements software engineering in development time reduction is specified. Market and software customers have large influence on software quality and price, development team structure and development time. They dictate rapid application development with certain time bounds. For small and medium sized projects monitoring, there is Fast Track model suggested. Fast Track is based on technologies that attempt to reduce development time performing activities concurrently and software delivering incrementally. Rapid application development, in non-specified requirements conditions, can be monitored by Dynamic System Development Model. This model is reducing development time performing iterative activities and by incremental software delivery. The large difference from standard software development models is Dynamic System Development Model involves software customers in whole development process, from the beginning to the end. Practical performance verification of the Waterfall model, Fast Track model and Dynamic System Development Model is performed by Generalised Stochastic Petri Nets usage. For simulation purposes, there is DNAnet tool used
