9. Questions so far? (c) De Montfort University 2011-12 All Rights Reserved9

10. What is system development (c) De Montfort University 2011-12 All Rights Reserved10  More than just developing an application system  Four stages  Inception = understanding business need and getting started  Elaboration = finding out and analysing user requirements, and designing logic of a system to meet the requirements  Construction = building and testing that system  Transition = implementing the developed system  In other words...  Work out what problem to solve  Work out what goes into solving the problem  Develop the system  Make it happen including training the users

11. Case Study (c) De Montfort University 2011-12 All Rights Reserved11  Module uses a case study including pre-written system  Scenario: second-hand bookshop  Partly on-line, partly in shop  Online: managing lists of books for sale, making reservations  Shop: paying for purchases  Users are buyers and/or sellers  Cashier does administration  System has been developed but there are holes in it  Some design documents exist and some are flawed  Some design documents do not yet exist  Not all functions work as you would expect

12. Case study, contd (c) De Montfort University 2011-12 All Rights Reserved12  During the year, you will evaluate system....  Work out what you expect it to do  Test it to see if it does those things  Work out what design documents are missing  Work out what design documents need fixing  Write evaluation report ...and complete the design documentation...  Create missing documents  Fix flawed documents  Write requirements specification

13. Case study, contd (c) De Montfort University 2011-12 All Rights Reserved13 ...and consider users...  Different types of user and what their needs might be  Check that different needs are met in designed system  Write user guide ....and test system...  Write test strategy and plans  Carry out planned tests  Write report of faults and suggested improvements  Think about extensions to system ...and present your findings  Summary of faults and improvements and proposed extensions

14. Study Skills (c) De Montfort University 2011-12 All Rights Reserved14  Note taking  Get in the habit of taking notes, using lecture handouts to start  Look up things you don’t understand  In module text books, in library, on Google Scholar  Use the library  Online through MyDMU, or in person  Study guides, report-writing sessions and so on  Blackboard  Get in the habit of checking for recent announcements  Module material loaded and released when appropriate  Keep on top of the work  Get in the habit of planning your time and sticking to the plan

15. Study Skills, contd (c) De Montfort University 2011-12 All Rights Reserved15  Ask your tutors  If you don’t understand something....  If you feel you are falling behind....  If you need to tell us something.... ....just talk to us, we are here to help!

16. Question Time (c) De Montfort University 2011-12 All Rights Reserved16  Are there any questions about any of this?

17. ...and finally.... (c) De Montfort University 2011-12 All Rights Reserved17  Enjoy learning about system development!
