Chapter 11 - Systems design. In this chapter you will learn more about the design phase of systems development. You will know that you understand the process of systems design when you can: Describe the design phase in terms of your information building blocks, identify and differentiate between several systems design strategies, describe the design phase tasks in terms of a computer-based solution for an in-house development project,. | Chapter 11 Systems Design This repository of slides is intended to support the named chapter. The slide repository should be used as follows: Copy the file to a unique name for your course and unit. Edit the file by deleting those slides you don’t want to cover, editing other slides as appropriate to your course, and adding slides as desired. Print the slides to produce transparency masters or print directly to film or present the slides using a computer image projector. Each slide includes instructor notes. To view those notes in PowerPoint, click-left on the View Menu; then click left on Notes View sub-menu. You may need to scroll down to see the instructor notes. Objectives Describe the design phase in terms of your information building blocks. Identify and differentiate between several systems design strategies. Describe the design phase tasks in terms of a computer-based solution for an in-house development project. Describe the design phase in terms of a computer-based solution involving procurement of a commercial systems software solution. No additional notes Systems Design Systems design – the specification of a detailed computer-based solution. Also called physical design. Systems analysis emphasizes the business problem Systems design emphasizes the technical or implementation concerns of the system. No additional notes Systems Design Approaches Model-Driven Modern structured design Information engineering Prototyping Object-oriented RAD JAD Teaching Notes These will be expanded upon in the next slides. Model-Driven Approaches Model-driven strategy – a system design approach that emphasizes drawing system models to document technical and implementation aspects of a system. Teaching Notes Note that modern structured design is the first of three model-drive approaches that will be discussed. Model-Driven Approaches – Modern Structured Design Modern structured design – a system design technique that decomposes the system’s processes into manageable . | Chapter 11 Systems Design This repository of slides is intended to support the named chapter.
