Module 7 Case Study/Review

1. “Planning and budgeting processes are notorious for their rigidity and irrelevance to management action.” How can planning be made relevant to the challenges facing a business?

You can discover innovative approaches to satisfying a company’s customer value and business value goals. This planning process leads to the development of strategies and business models.

2. Why has prototyping become a popular way to develop business applications? What are prototyping’s advantages and disadvantages?

* Prototyping makes the development process faster and easier for IS specialists and business professionals.

* Prototyping makes the development process faster and easier, especially for projects where end user requirements are hard to define. Thus, prototyping is sometimes called rapid application design (RAD).

* Prototyping has also opened up the application development process to end-users because it simplifies and accelerates systems design. These developments are changing the roles of end users and information systems specialists in systems development.

Advantages:

* Prototyping is most useful when there is some uncertainty about requirements or design solutions.

* Prototyping is especially useful in designing an information system’s end user interface (the part of the system that end users interact with, such as online display and data entry screens, reports, or Web pages).

* Since prototyping encourages intense end user involvement throughout systems development, it is more likely to produce systems that fulfil user requirements.

Disadvantage:

* Rapid prototyping can gloss over essential steps in systems development. If the completed prototype works reasonably well, management may not see the need for reprogramming, redesign, or full documentation and testing to build a polished production system.

* Hastily constructed systems may not easily accommodate large quantities of data or a large number of users in a...
