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...
