5 © Devon M.Simmonds, 2007 What is Software Engineering (SE)? Software Engineering is concerned with development of complex systems that are built by teams of developers. SE techniques are not intended for small problems (e.g., writing a program for sorting a list of numbers). On the other hand, SE builds upon programming techniques; a good software engineer must also be a good programmer. SE research focuses on developing mechanisms and methods that help developers manage system complexity.

6 © Devon M.Simmonds, 2007 A Definition of SE The establishment and use of sound engineering principles in order to obtain economically software that is reliable and works efficiently on real machines. Bauer/Pressman

7 © Devon M.Simmonds, 2007 The Software Lifecycle The process/activities of developing and evolving software Systems Engineering Requirements Analysis Software Design Implementation Testing Deployment Evolution

8 © Devon M.Simmonds, 2007 The Software Lifecycle Systems Engineering Identify needs/problems Allocation of roles Hardware Procedures Software Feasibility studies Systems Engineering Requirements Analysis Software Design Implementation Testing Deployment Evolution

9 © Devon M.Simmonds, 2007 The Software Lifecycle Requirements Analysis Define goals, objectives, features of target software Requirements Analysis Software Design Implementation Testing Deployment Evolution Systems Engineering Identify needs, problems and allocate roles

10 © Devon M.Simmonds, 2007 The Software Lifecycle Software design Creating a blueprint for building the software Architectural design Subsystem design Detailed design Procedural Design User Interface Design Database Design Data Structures Design Test case design Requirements Analysis Software Design Implementation Testing Deployment Evolution Systems Engineering Identify needs, problems and allocate roles Define software features “Up to 70% of all faults detected in large-scale software projects are introduced in requirements and design. Detecting the causes of those faults early may reduce their resulting costs by a factor of 100 or more.”

12 © Devon M.Simmonds, 2007 The Software Lifecycle Testing Determining if the software has errors/fulfils its requirements Test planning Unit testing Subsystem testing Integration testing Regression testing Test case design Requirements Analysis Software Design Implementation Testing Deployment Evolution Systems Engineering Identify needs, problems and allocate roles Define software features Create blueprint Create code

13 © Devon M.Simmonds, 2007 The Software Lifecycle Deployment Making the software available for use Deployment/installation planning Develop documentation Hardware configuration Installation Software distribution Training Requirements Analysis Software Design Implementation Testing Deployment Evolution Systems Engineering Identify needs, problems and allocate roles Define software features Create blueprint Create code Uncovering errors

14 © Devon M.Simmonds, 2007 The Software Lifecycle Evolution Managing the software Configuration management Controlling change as software evolves Technical support Software lifecycle activities Requirements Analysis Software Design Implementation Testing Deployment Evolution Systems Engineering Identify needs, problems and allocate roles Define software features Create blueprint Create code Uncover errors Make software available for use

15 The Software Lifecycle: The Unified Process 15

16 © Devon M.Simmonds, 2007 Important Topics In SE Lifecycle phases Analysis, design, etc Research methods in SE Literature review and analysis Model driven software development (MDD) Aspect-oriented design & analysis Component-based software engineering Design patterns in SE Measurement Software processes Software testing Etc.

24 Research Excellence: Rules to Guide the Supervision Process Always seek feedback from your supervisor before any important decision. Asking persons to serve on your committee. Requesting feedback about your project from the committee (informal feedback is of course allowed). Requesting feedback on your project … a survey instrument, software to be evaluated, etc. © Devon M.Simmonds, 2007
