Systems Analysis and Design: Chapter 6 - Agile Modeling and Prototyping's Objectives is Understand the roots of agile modeling in prototyping and the four main types of prototyping; Be able to use prototyping for human information requirements gathering. | Agile Modeling and Prototyping Systems Analysis and Design, 7e Kendall & Kendall 6 © 2008 Pearson Prentice Hall Learning Objectives Understand the roots of agile modeling in prototyping and the four main types of prototyping Be able to use prototyping for human information requirements gathering Understand the concept of RAD for use in human information requirements gathering and interface design Understand agile modeling and the core practices that differentiate it from other development methodologies Learn the importance of values critical to agile modeling Understand how to improve efficiency for users who are knowledge workers using either structured methods or agile modeling 6- Kendall & Kendall Agile Modeling, but First Prototyping Agile modeling is a collection of innovative, user-centered approaches to systems development Prototyping is an information-gathering technique useful in seeking user reactions, suggestions, innovations, and revision plans 6- Kendall & Kendall | Agile Modeling and Prototyping Systems Analysis and Design, 7e Kendall & Kendall 6 © 2008 Pearson Prentice Hall Learning Objectives Understand the roots of agile modeling in prototyping and the four main types of prototyping Be able to use prototyping for human information requirements gathering Understand the concept of RAD for use in human information requirements gathering and interface design Understand agile modeling and the core practices that differentiate it from other development methodologies Learn the importance of values critical to agile modeling Understand how to improve efficiency for users who are knowledge workers using either structured methods or agile modeling 6- Kendall & Kendall Agile Modeling, but First Prototyping Agile modeling is a collection of innovative, user-centered approaches to systems development Prototyping is an information-gathering technique useful in seeking user reactions, suggestions, innovations, and revision plans 6- Kendall & Kendall Prototyping and RAD (rapid application development) can also be used as an alternative method to SDLC. Major Topics Prototyping Rapid application development (RAD) Agile Modeling 6- Kendall & Kendall Prototyping Patched-up Nonoperational First-of-a-series Selected features 6- Kendall & Kendall Information gathered in the prototyping phase allows the analyst to set priorities and redirect plans inexpensively, with a minimum of disruption. Patched-Up Prototype A system that works but is patched up or patched together A working model that has all the features but is inefficient Users can interact with the system Retrieval and storage of information may be inefficient 6- Kendall & Kendall In engineering this approach is referred to as breadboarding. Users can interact with the system – getting accustomed to the interface and types of output available. Retrieval and Storage of information may be inefficient – programs were written rapidly with the objective of being workable .
