Q

Why do organizations continue to change their information system?

A

There are many reasons why organizations continue to change their information systems whether it’s a full systems replacement or an upgrade to an existing system. This can be due to technology changes, to become more effective and efficient in the organization (productivity gains), or for competitive advantage reasons.

Dempster’s Triangle (Triple Constraints)
Scope
Time
Cost
Scope Creep – broadening of project scope after the project has started. The larger the scope expands, the further the project will move away from the original purpose, timeline, and budget.

PERT chart – works to identify all tasks of a project.

  • Notes task sequencing and task dependence.
  • Notes critical path – the path that represents the minimum amount of time needed for the completion of the project when sufficient resources are allocated.
63
Q

Bar chart that organizes activities on the left hand side and project time scheduled with a bar drawn to show the progress to date for that particular activity.
The Gantt chart is a good way to visualize how the activities break down and are scheduled for the entire IS project.

66
Q

Why people resist change?

A

Change is hard, think about a time when you had to change your habits, how successful were you the first time?
Did it take practice and setting your mind to it?

Disruption
-Additional requests for information and additional burdens of time is distracting and prompts negative feelings
Manner change is introduced
-Approaches are different for top level and lower level employees
Biases and emotions
Personal characteristics and background
