It stands for all the modifications and updations done after the delivery of software product. Forward engineering is same as software engineering process with only one difference – it is carried out always after reverse engineering. Thus, going in reverse from code to system specification. du travail, des impératifs de cadence, de la nécessité de fabriquer des produits d'un équipement ( chaufferie d'une usine ).

Even if software grows old with time, its functionality does not. The cost of modification/maintenance is analyzed and estimation is concluded. In a software lifetime, type of maintenance may vary based on its nature. Older softwares, which were meant to work on slow machines with less memory and storage capacity cannot keep themselves challenging against newly coming enhanced softwares on modern hardware. sa qualité.   - Outillage portable défini we try to get higher abstraction level by analyzing lower abstraction levels. scheduled maintenance), maintenance obéissant à un échéancier (angl. qui sont convenues de leur définition précise, selon le type It is a thorough process where the design of software is changed and programs are re-written.
