First of all, most of the times the purchasing of a product means access to free online updates, released by the company. ]]> 2021-12-10 14:12:39 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940406477 1.

Change management involves various parameters and the process of shifting individuals, teams, departments and organizations from the present state to a desired state. ]]> 2021-12-10 14:26:48 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940437693 Compatibility issues mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940502914 1. Keep both information systems, and develop them to have the same functionality (high maintenance cost) 
  1. Replace both information systems with a new one (increased initial cost). 
  2. Select the best information systems from each company and combine them (it is very difficult for the employees to work with information systems from another 
company).
4. Select one company's information systems and drop the other companies’ (policy problems).

For this reason, the last step to this concept is user training, where users understand completely how they need to use it by:
Self-Instruction or self-study 
Formal classes 
Remote/distance learning/online training]]> 2021-12-10 15:30:56 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940575646 Importance of user documentation mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940607850 Programs and systems may become increasingly complex as their aim gets more and more and convoluted. ]]> 2021-12-10 15:46:51 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940607850 Consequences of data loss in a specified situation mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940666443 For example, if the medical records of a patient in a hospital are lost, then the patient’s life can be in danger if the data cannot be retrieved, and some painful examinations might have to be repeated. ]]> 2021-12-10 16:16:28 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940666443 Prevent data loss mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940668509 Regular backup of files using hard disks or magnetic tapes

It is considered as a failsafe method. ]]> 2021-12-10 16:19:24 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940672408 mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940672961 A failover system is a computer system which is on standby capable of switching to a spare computer system upon hardware failure, network failure, or any other type of error, such as software malfunction. The main difference between a failover and a switchover is the degree of needed human intervention. ]]> 2021-12-10 16:19:42 UTC https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940672961 mfernandez348 https://padlet.com/mfernandez348/eahiw5e32bu49hus/wish/1940683408 Patches are used by software companies to update applications by fixing known bugs and vulnerabilities.
