system development life cycle 2.0 / 5 based on 1 rating ? ComputingASOCR Created by: cristina lumbrerasCreated on: 23-02-13 15:20 system life cycle is a process to create a system that involves the following steps 1 of 20 feasability is the solution possible? economical to produce? 2 of 20 analysis this defines the problem that needs to be solved 3 of 20 design working out the best method to solve the problem 4 of 20 implementation is the process of creating the system and putting it in to the working place. there are a couple of types:direct, parallel and pilot conversion 5 of 20 maintenance this is the process of keeping the system running smoothly, ironing out glitches and adapting it if the problem changes 6 of 20 deliverable this is the final system that is produced given to the client 7 of 20 waterfall method one step followed by the next step, followed by the next following into the next 8 of 20 spiral method rapid prototyping followed by extensive maintenance to make it suit the problem 9 of 20 requirement specificaion what is needed to do 10 of 20 DFD data flow diagrams 11 of 20 system flowcharts a way of representing data flow around the system 12 of 20 data dictionary a list of every pice of data that is stored in the system 13 of 20 dry run testing walking through the process ignorign existing flows 14 of 20 unit testing testing small sections of the program to make sure it function properly 15 of 20 integration testing the process of bringing all the modules together and testing them together 16 of 20 system testing testing everything on the complete product 17 of 20 acceptance testing these are automated test written by the customer to check that the system has been implemented properly 18 of 20 blackbox testing algorithms 19 of 20 phased implementation parallel new and old system run at the same time 20 of 20
