Software specification (los yog xav tau engineering ): Txhais lub ntsiab functionality ntawm lub software thiab tej kev txwv nyob ib ncig ntawm lawv.

Ntxiv rau qhov no, txhais li cas los ntawm software txheej txheem?

Lub sij hawm software qhia meej rau cov txheej txheem khoos phis tawj, cov txheej txheem thiab cov ntaub ntawv cuam tshuam (Flowcharts, phau ntawv qhia, thiab lwm yam) uas piav qhia txog qhov program thiab lawv yuav siv li cas. A txheej txheem software yog cov txheej txheem ntawm kev ua ub ua no thiab cov txiaj ntsig sib koom ua ke uas tsim tau ib qho software khoom.
