Chapter 10, Problem 18RQ
Explanation of Solution
Basic conversion strategies:
There are four basic conversion strategies which is used at what time of converting into new system. They are,
- Direct changeover
- Phased implementation
- Pilot implementation
- Parallel operations
Direct changeover:
The direct changeover is also referred as cold turkey which helps to ending the old method and staring the new method.
- This is simple strategy that employees follow the existing procedure for one week, and then later use a new procedure.
- Some direct changeover is simple, such as a modification that includes requiring workers to use a new password starting on an announced date.
- Some may be complex, such as requiring the complete company to modify procedures at time of network team restricts an old firewall and starts a new one.
- The major problem of direct changeover approach is that when new system fails or required for changes, then the system’s bugs are worked out without help of user services.
- The new system testing in advance helps to decrease the possibility of these problems.
Phased implementation:
The phased implementation is the common conversion strategy and includes rolling out a system part over the whole organization.
- This mean that the security group implements a small part of the new security outline, then giving chance to users to get used to it and solving the small problems as they rise...

Level-0 Diagram for this: A customer sends in an order form containing details of their order and their membership number. A check is made to verify that they are a member. When their order is verified, a check is made to validate that the items ordered are produced by the company. Next, the valid order is used to update the daily order file, and then used to create a shipping list and invoice, which are sent on to the Order Fulfilment System.
In this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like.
The program must include a minimum of:
5 circles
5 polygons
5 line commands
2 for loops
1 global variable
You may wish to use the standard code for simplegui graphics below:
import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start()
Submit Your Code
After you write your code here in the programming environment, you will check it and submit it as usual. However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.
1. What is the difference between a relative cell reference and an absolute cell reference and give an example of when you would use each.
