5. Systems development process

Developing an information system from concept and requirements, through development, implementation and eventual retirement is a process – a series of steps and tasks with limitations on time, resources and cost.

There are lots of tools and techniques that improve the systems development process and the systems that are built. Some systems can take thousands of man-hours and millions of dollars to develop, then that much effort again to install the system and train all the users and support staff. For example, when one bank acquires another, it takes years to combine all their customer records, train branch personal and inform all the customers. We will look at some of the thinking and planning that goes into a big project like this.

Learning more than you already know about each topic will be very different for everyone in the class. The course topics, selected media. keywords and assignments are intended to guide you discovery and learning. It is up to you to find a good starting place. The I know.. assignments should be a brief statement of what you think you know before you start work on the topic. If you don’t know much, that is ok. There are should be selected that provide the basics so that you can get an understanding of the topic. If not, let me know. We will try to find something that provides a better starting point for you. As this is a new version of the course, there may be some areas that need better resources and more explanations.

Let me know if you have questions. This is especially important in an online class – I can’t walk around the class and see a puzzled look on your face. If you don’t ask, I don’t know you need help.
